How an Air Conditioner Works?

We've observed the history of AC and the newest trends in what contemporary ACs provide. However, some might not be certain how air is warmed or chilled. Let us walk you through fast how an air conditioner works.

Basic Mechanism and Principle

The underlying principle of the evaporative cooling system is that water should have heat, called the"heat of vaporization," applied for it to switch from a liquid into a vapor.

By way of instance, touching rubbing alcohol hydrates your finger since it absorbs heat from your skin as the alcohol evaporates. This signifies the principle of an evaporative cooling system.

Conversely, when the gas liquefies, it releases a great deal of warmth, and that's the way that evaporative heating occurs. A MarQ AC review indicated that the air conditioners work with these principles.

A liquid known as a"refrigerant" circulates through a closed piping system, occasionally liquefying and evaporating to cool air, and reversing this refrigerant flow (reverse cycle) heats the air.

Refrigeration Cycle

Compounds alter the condition, i.e., liquid, solid, gas, normally when they are heated or chilled. That's known as"altering conditions of matter."

Air conditioners influence the changes in conditions of refrigerant to heat or cool room atmosphere. The refrigeration cycle constantly changes the conditions of a refrigerant circulating in a closed piping system.

1. Compressing

After the cooling procedure begins, the refrigerant in reduced temperatures and pressure will be compressed by the compressor.

The warmth of the gas increases, whereby making the refrigerant gaseous in elevated temperature and pressure.

2. Condensing

The gaseous refrigerant is moved into the condenser (heat changer), in which heat is exchanged between the refrigerant and outside air.

This releases the refrigerant‘s heat into the outside air. Releasing the warmth, the refrigerant changes its state to some medium-temperature and high-temperature liquid.

3. Expansion

The liquefied refrigerant goes to the growth valve, which reduces the stress of the refrigerant. Depressurized refrigerant expands, decreasing the temperature and shifting its own state to some liquid of low temperatures and pressure.

4. Vaporization

The refrigerant becomes a low-temperature and low-pressure liquid in the expansion valve and is moved into the evaporator (heat exchanger), in which heat is exchanged between the refrigerant and indoor atmosphere.

The warmth of the indoor atmosphere moves into the refrigerant, and the atmosphere is chilled. The refrigerant picks up the warmth from the atmosphere, shifting its state to some low-temperature and low-pressure petrol, and also goes straight back to the breaker.

5. Reverse Cycle

A heat pump air conditioner utilizes a four-way valve that reverses refrigerant flow, offering you both heating and cooling for air comfort relaxation throughout the year.

This function is also known as a"reverse cycle." The expression"reverse cycle air conditioner," yet another title for a heat pump air conditioner, comes in the mechanics of this cycle.

6. Compressor

An air conditioner compressor can be described as a part of the system which increases the pressure of the vapor to create changes from the refrigerant temperature. Most home-use air conditioners have compressors within their outside units.

7. Heat Pump

Heat flows from hot to cold. A heat pump reverses flow by extracting heat from a place and transfers it into another.

Based on if the heating or cooling system is chosen, it pushes heat out and in with the heating cycle of compression, then condensation, then expansion, and finally, evaporation.

8. Inverter

A power inverter, or just inverter, is a digital apparatus or circuitry that changes direct current (DC) to alternating current (AC). Most commercial and domestic buildings are often powered by AC.

Standard voltages and frequencies vary by state. Changing voltage or frequency demands an inverter that converts AC into DC and, following desired changes in voltage and frequency, converts DC back to AC.

Air conditioners with inverters operate at controllable motor speeds—a cool method for electricity conserving.

9. Water-Cooled Chiller System

A water-cooled chiller system includes a chiller that uses water as the refrigerant and may be seen in several industrial and commercial uses.

The water picks up heat within the building, returns into the chiller, in which it's cooled, then returns to circulating throughout the building.

10. Cooling Tower

A cooling tower, sometimes located on rooftops, is a heat rejection device that aids refrigerated ac work efficiently. Heat exchange happening at the refrigeration unit raises the temperature of the heating water.

The cooling tower keeps and exposes the water to airflow to the tower to permit air, which lowers the water flow. Afterward, the water has been passed back into the refrigerant unit and used again.

11. Free Cooling

Free heating is an economical way of utilizing low outside air temperatures to help in chilling water. The heated water could be stored until used and summer from the cooling system to discharge heat.

If the ambient air temperature drops into a set temperature, then a modulating valve permits the heated water to jump-start a present chiller and operate via the free cooling procedure, which requires much less power to cool the water from the system.

What Is Humidity Control?

Reduced humidity contributes to a dry atmosphere, which causes mucous membranes in your throat to become less resistant to influenza pathogens and other ailments.

Too much humidity, flipping the coin, causes distress. After the humidity of the atmosphere rises, it permits the development of biological contaminants like mites and mold.

The American Society of Heating, Refrigerating & Air-Conditioning Engineers (ASHRAE) urges that indoor relative humidity be maintained between 40-60 percent.

The Difference Between AC and Dehumidifiers

A whole lot of air heaters function as dehumidifiers. Air conditioning (cooling) is a process that prioritizes the lowering of space temperatures.

Therefore, once the cooling system is chosen on an AC, then it proceeds to cool the air until it drops to a perfect temperature.

Dehumidifiers are made to decrease the humidity level of a certain distance and operate a feeble cooling manner until the preset humidity is attained.

A few dehumidifiers can dehumidify and reheat to generate a room environment using a drier atmosphere without reducing temperatures.

Applications

Air conditioning is all about producing desirable air environments for objects or occupants indoors. Air-conditioning programs are widely divided into relaxation and process applications.

Comfort application

With relaxation air conditioning, the focus is on individuals residing, working, etc., at office buildings, health centers, schools, shops, or even vehicles.

Low-Rise Apartment Buildings and Single-Family Homes

Packaged window unit (in-window) ACs or split system ACs would be the favorite options for homes and low-rise flat buildings. Split-system air conditioners come in 2 kinds: single-split and multi-split systems.

A single-split system is generally composed of a single indoor unit and a single outdoor unit, even though a multi-split system includes two or more indoor units.

The kind of system, space dimensions, and functions required are typical elements to be thought about in choosing an air compressor.

High-Rise Housing, like Condos

The bigger the building, the higher complications there will be in the AC system. Ac methods for high-rise homes are broadly categorized into two types from the way the heat source is dispersed: distributed heating and central heating.

A central heating system offers heat to the total inside of a building from 1 stage (e.g., a machine room, in which heat sources such as a boiler and heating unit are placed) to multiple chambers.

In a dispersed heating system, heating sources can be found at multiple factors where air conditioning for chambers of ground or zone is supplied.

Public Institutions, e.g., Schools, Hospitals

An educational institution or Medical center buildings have spaces with various purposes, so they require particular designs suitable for the function of how they're used.

By way of instance, waiting rooms or workplaces need typical relaxation air conditioning, even while managing rooms or kitchens need to be made to satisfy function-specific requirements.

Office Buildings

Office buildings provide spaces for businesspersons, which could be hot weather individuals or who favor temperatures somewhat lower.

Airflow instructions ought to be made select-able for comfy air conditioning. In designing a system, uninterrupted exposure to drafts from an AC should likewise be avoided.

Commercial Buildings that Accommodate Restaurants, Shopping Malls

Commercial buildings home varying companies that need various abilities of air conditioning when all tenants have the exact same place.

When there's a restaurant at the construction, ease of upkeep and also an oil-trapping filter system ought to be contemplated in the air conditioning layout because of its own kitchen space.

For industrial buildings, tenant-centric air conditioning together with desired indoor unit layouts and outside unit designs offering comfort for clients is an extra requirement.

Industrial Buildings

Along with relaxation, industrial air-conditioning design may demand cooling equipment for tooling and machines. Cooling the huge area of an industrial center requires significantly big power output.

That's the reason it's often suggested to utilize the ease of fans or spot coolers to decrease the total electricity consumption.

Road, Marine, and Air Vehicles for Carrying fresh food items or Passengers

Buses, railways, aircraft, refrigerated vehicles, and boats --they need air conditioning programs appropriate to the requirements of what they carry.

Public vehicles tend to get packed with lots of men and women, which makes it crucial to be well ventilated along with controlling the humidity and Temperature.

For aircraft, the cabin pressure has to be kept at a constant degree so as to make a secure and comfortable environment for crew and passengers flying at high altitudes.

Process Applications

Process applications aim to offer a suitable environment, e.g., inner heating and humidity heaps, for a procedure being completed, in addition to for machines or material used for this.

Process applications include industrial surroundings; farm and plant growing areas; meal consumption, processing, and storage areas; and ecological management of information centers.

Biological Clean rooms

Facilities for breeding lab animals have to be air-conditioned to particular requirements so as to present an environment for getting highly dependable information.

Humidity and Temperature need to be ideally controlled to levels suitable to animals being bred. Interior air has to meet cleanliness requirements and also be correctly deodorized.

Data Centers

Air conditioning for information centers must curb heat generation from servers and computers, also, at precisely the exact same period, distribute the conditioned air to match the thermal relaxation needs of people.

Capabilities for maintaining moderate humidity amount and conserving energy have to also be factored into the atmosphere condition planning.

Operating Theaters

Fundamental demands for air conditioning systems in working theaters include the regulation of humidity and Temperature and the atmosphere relaxation for patients and healthcare professionals.

Operating rooms have to get a positive pressure connection to adjoining places, i.e., a pressure inside has to be retained higher than the environment which surrounds the space.

Types of Air Conditioning Systems

The classification of home-use AC contains:

In a window AC, each of the elements, namely the compressor, condenser, expansion valve or coil, evaporator, and heating coil, are included in one box package. This device is fitted in, generally, a windowsill, eliminating the need for ducting.

Split: The split AC consists of two components -- the outside unit and the indoor unit -- also comes in only divide or multi-split settings.

Single Split System: In one split air conditioner, one exterior unit runs the machine to supply conditioned air from an indoor unit.

Multi-Split System: The outside unit of a multi-split air purifier operates more than one unit. A favorite alternative for owners of recently constructed homes. As it requires just 1 unit outside, a multi-split system leads to a slick house look.

Requirements for Multi-Split System Installation

These needs should be taken into account.

Piping Routes: A multi-split platform requires piping to connect with the outside unit and several indoor units. Dimensional constraints ought to be assessed beforehand to be sure of the installation of piping.

Outdoor Unit Capacity: The entire power of the indoor components needs to be kept under the capability of the outside unit.

Air-to-Water (AtoW) Heat Pump

An AtoW heating pump pushes heat from the atmosphere to heat the refrigerant. Just like a split system air conditioner, the AtoW process is comprised of an indoor unit and an outdoor unit.

Heated water is kept in a tank within the indoor system and used for drinking, cleaning, indoor air heating, or ground heating.

The technology uses heat from the atmosphere and has been drawing attention from Europe, where environmental issues are prompting individuals to move from traditional combustion boilers into systems that are not as impactful on the environment.

Types of AC Systems -Commercial Air Conditioning

Different types of Air Conditioning Systems -Commercial Air Conditioning

Cooling/heating ability is where commercial/industry air conditioning systems appreciably differ from home ACs.

Commercial/industry air conditioning systems are approximately categorized, by their capability, into people for medium-size offices or shops and people for buildings and massive facilities.

Indoor units arrive in many different forms to meet varying demands, which are characterized by applications and space volume.

Office/Store Air Conditioning Systems

Single-Split Packaged Air Conditioners: In one split air conditioner, one exterior unit runs on the system, which offers conditioned air from an indoor unit.

Multi-Split Packaged Air Conditioners: At a multi-split air conditioner, a single exterior unit operates greater than an indoor unit, which makes it a favorite alternative for owners of shops and standalone offices.

Packaged Terminal Air Conditioners: A PTAC or packaged terminal air conditioner is a ductless, self-contained heating and cooling system (through the wall) commonly found in resorts, home centers, and apartment buildings.

With indoor air units and outside heating units connected through partitions, PTACs are installable in a more compact region and supply individual ac.

Building/Factory Air Conditioning System

VRF/Mini VRF

At a variable refrigerant flow (VRF) system, one exterior unit operates greater than one unit. VRFs are generally installed in moderate to large buildings larger than shops or standalone offices, for which multi-split packed air conditioners will be the favorite option.

Being controlled at varying speeds, VRF units adapt to the desired speed allowing for considerable energy savings. The ones that arrive with streamlined outdoor units made for small to midsize buildings are known as mini VRFs.

Gas Heat Pump (GHP) AC System

A GHP air conditioning system includes a gasoline engine-powered compressor within the outside unit and a heat pump to cool or heat air in living areas.

Chiller: A chiller is a machine that removes heat from a liquid by means of a vapor-compression or absorption cooling cycle. This liquid, known as a refrigerant, is circulated through a heat exchanger to cool gear.

Chillers are in use for industrial computers and lab instruments to always maintain optimal temperatures. Commercial factories and buildings use chillers for air conditioning.

Air Handling Unit (AHU): The AHU or air handling unit is a device utilized to modulate and circulate air being part of the heating, ventilating, and conditioning system.

It utilizes cold/hot steam or water to regulate the humidity and temperatures of the atmosphere that flows into living spaces.

Central Air Conditioning: In a central ac system, a heating device apparatus installed at the construction heats the water flow in the system.

The water flows into and out of an AHU to supply conditioned air. That's compared to individual ac systems, which have heating resources for each ground and area.

Kinds of Indoor Units

Indoor components of commercial/industrial air conditioners are available in a variety of forms, based on space geometries and software.

Ducted: Indoor components of a ducted air conditioner are set up in the ceiling area. The air inlet/outlet grilles are the only components visible on the ceiling.

Wall-Mounted: The indoor system is wall-mounted and completely exposed.

Ceiling Cassette: The indoor unit of an inbuilt cassette AC is installed in the ceiling area. The ceiling panel is the only component visible and exposed on the ceiling. The valves and unit, being at the ceiling, are less observable and from the way.

Ceiling-Mounted: The indoor unit has been mounted onto the ceiling and exposed.

Floor: Being put on the ground reduces the time needed for setup.

Additional Gear for Air Conditioning

Below are apparatuses that assist air heaters to provide greater room air

Air Purifier: An air conditioner or air cleaner is a device that eliminates contaminants, e.g.dust, pollens, house dust, in the atmosphere in an area to enhance the quality of indoor air.

Ventilation Fan: An air conditioner offers cool/hot airflow but doesn't ventilate. Employing fan venting, together with an air purifier, guarantees new air consumption all the time.

Fan: Utilizing a fan with air conditioning boosts the heating impact without lowering the temperature. Fans can also be helpful to efficiently produce cool air in spaces that are stuffy.

Heater: It takes some time to heat the whole room with an air conditioner in wintertime. Fan heaters boost the heating efficiency of air conditioning systems being used.

Selecting an Air Conditioner Which Best Fits Your Space

Choosing an Air Conditioner Which Best Fits Your Space

The AC's capacity is the very first component to be factored in if picking the right business AC system for your company.

To ascertain the capability required, you might also take into consideration other variables; for instance, is your area facing south, or does this have big windows.

Select one that best matches the dimensions and demands of the rooms, supplies relaxation, and conserves electricity.

Controls

Advances in communication technologies permit more air conditioning systems to become community-linked. Let's walk you through a few examples of exactly what recent air heaters offer.

Wireless LAN (WLAN) and Application Controls

The most recent air conditioners have wireless LAN (WLAN) connection capacity that provides users smartphone controllers across the net.

You are able to turn in your air conditioner when you're away, which allows you to come home to a comfy temperature.

Remote Controls

Most ACs have remote controls. They provide features like big-screen LED, ease of use, fast press buttons, and much more.

Virtual Personal Assistant (VPA)

A digital private assistant (also known as a smart digital helper ) is a software agent that provides answers and executes services or tasks for a person based on orders or queries—dialogues with the short-range leverage natural language processing technology.

Artificial intelligence and voice recognition technology embedded inside the unit allows voice control over ACs and other electronics.

Building Management System (BMS)

A building management system (BMS) is a pest management control system installed in buildings that electronically and mechanically controls and tracks the construction systems like access control, security systems, fire systems, lighting, elevators, and ac.

Smart Cloud

Cloud computing is a type of computing usage, generally, the on-demand access to computer system resources, notably data storage and computing power, without immediate active direction by the consumer.

It provides services via network-connected computers (servers) to customers' personal computers or smartphones. Nowadays, smart cloud solutions are quickly being developed after another to deliver transformation in contemporary ac.

1 illustration is Panasonic's AC Smart Cloud. It monitors the energy consumption levels, capabilities, performance performances of numerous AC devices in various locations through cloud computing methods.

Users have fast and effortless access to this information from their tablet computers or private computers to ensure sound operations of their devices, and they're ready 24/7 to respond in case of an error.

Bluetooth

Bluetooth can be described as the short-range wireless communication technology that enables apparatuses and devices to transmit voice or data wirelessly within a brief distance.

The tech is the exact same one that lets you listen to music being streamed onto your smartphone via wireless earphones.

Some recent light goods and air conditioners equipped with Bluetooth technology, capable of connecting with smartphone programs, are getting much attention in the marketplace.

Zigbee

Zigbee is a wireless community specification for high-level communication protocols for closeness (i.e., private area) wireless ad hoc networks.

The tech characterized from the Zigbee specification provides restricted transfer speed and distance in exchange for less costly as well as working on lower electricity.

Devices supporting Zigbee supply remote-controlled home automation for air conditioners, lightings, TVs, displays, drapes, and other things.

BACnet

BACnet can e described as a communications protocol for building BAC (automation and control) networks.

The BACnet protocol provides mechanisms for automatic building automation devices to swap and track data, irrespective of the construction service that they function according to manufacturer specifications for air conditioning, power, or fire extinguishing systems.

Modbus

Modbus is a serial communications protocol that's published by Modicon (currently Schneider Electric) to be used with its own programmable logic controls (PLCs).

It is now a de facto standard communication protocol and is currently a commonly available way of linking building management systems (BMS), fabricating machines, boilers, and other industrial digital devices.

The Latest Air Conditioning Characteristics That Increase the Quality of Life

ACs are active in bringing relaxation around the calendar year, specifically during winter and summer. Thus, be a knowledgeable consumer and understand what they provide. Let us have a peek at the most recent features on Panasonic air conditioners.

Fan Speed/Coverage

An air conditioner fan circulates the heated or cooled air inside the room. The coverage and speed of this enthusiast impact the cooling/heating efficiency. Air conditioners with variable fan speeds and broad coverage lower/raise the room temperature fast.

Operating Modes

Normal working modes include:

Cool: Discharges indoor warmth to decrease the room temperature.

Auto: Automatically changes and selects ways to maintain the room temperature at the designated level.

Dry: Dehumidifies the room atmosphere. Additionally frees the room atmosphere, but much less efficiently in a cool manner.

Heat: Squeeze outside warmth to inside to heat the room atmosphere.

Eco: Runs the air conditioner when restricting energy consumption.

Fan Only: Flows air to the space to provide a cool breeze with no cooling or heating system.

Human Sensor

Detects the presence of a body in a room and directs warm or cool breeze in this way. Increases air conditioning efficiency and helps reduce energy intake.

ECONAVI, a complete range of Panasonic's latest technology, comprises sensor analysis on the way the space occupant feels exactly the temperature (i.e., cold or hot ), sunlight shifts, furniture/room design to deliver customized ac.

Air Filtering & Autonomous Cleaning

Modern-day ACs have advanced air filtering capacity to eliminate dust, mold, and bacteria that can be detrimental to human health.

Many air conditioners wash out the interior of components and curb dust pile-up or mold growth. These functions maintain air purifier filters clean around the clock, reducing energy reduction, consequently efficiently lowering your energy bills.

Night Mode

Night mode in an AC has often identified a very low power mode where auto-temperature control and end flow conserving are triggered for relaxation once the consumer is sleeping.

Once turned on, you can sleep peacefully without any worries about your area getting too warm or chilly.

Angle-Adjustable Louver Slats

Due to convection where cold air moves down, and hot air rises, air dissipates efficiently when louver slats in front of AC are turned up through down and cooling when heating.

Most versions have angle adjustment controls for louver slats in their remote controls. Sideways angle adjustment aids send a cool/warm atmosphere to a specific place within the room.

Delayed Restart

Delayed restart averts restart right after an AC is switched off to protect the compressor.

Demand Response Enabling Device (DRED)

Since the consciousness of global warming develops, demand response, a cap on the energy consumption of an electric utility client to prevent peaks in demand for electricity and maintain equilibrium with the source, is becoming a popular selection for electricity consumption control throughout the planet.

Australia has national criteria for Demand Response (AS/NZS 4755 chain ) on DREDs. This system was implemented nationally by power providers. Voluntary rationing for ACs and other electrical appliances is supported by means of price incentives.

Auto-Defrost

When an air purifier is run beneath low outside temperatures and higher humidity, frost may form on its exterior unit. As time passes, an accumulation of ice may form on the evaporator coil (cooling element).

Finally, this may block the flow of the chilly atmosphere. That is the reason why defrosting is needed. Auto-defrost frequently defrosts the evaporator by melting the freeze and sparks the consequent water from the unit.

Types of Heating Systems

Central Heat

Furnaces

The majority of North American households depend on a central furnace to provide heat. A furnace works by blowing heated air through ducts that deliver the warm air to rooms throughout the house via air registers or grills. This type of heating system is called a ducted warm-air or forced warm-air distribution system. It can be powered by electricity, natural gas, or fuel oil.

Inside a gas- or oil-fired furnace, the fuel is mixed with air and burned. The flames heat a metal heat exchanger where the heat is transferred to air. Air is pushed through the heat exchanger by the “air handler’s” furnace fan and then forced through the ductwork downstream of the heat exchanger. At the furnace, combustion products are vented out of the building through a flue pipe. Older “atmospheric” furnaces vented directly to the atmosphere, and wasted about 30% of the fuel energy just to keep the exhaust hot enough to safely rise through the chimney. Current minimum-efficiency furnaces reduce this waste substantially by using an “inducer” fan to pull the exhaust gases through the heat exchanger and induce draft in the chimney. “Condensing” furnaces are designed to reclaim much of this escaping heat by cooling exhaust gases well below 140°F, where water vapor in the exhaust condenses into water. This is the primary feature of a high-efficiency furnace (or boiler). These typically vent through a sidewall with a plastic pipe.

New furnace standards are currently under development by the U.S. Department of Energy, and are due to be finalized in the spring of 2016. The current furnace standards have not been updated since 1987.

Heating system controls regulate when the various components of the heating system turn on and off. The most important control from your standpoint is the thermostat, which turns the system — or at least the distribution system — on and off to keep you comfortable. A typical forced air system will have a single thermostat. But, there are other internal controls in a heating system, such as “high limit” switches that are part of an invisible but critical set of safety controls.

The best gas furnaces and boilers today have efficiencies over 90%

The efficiency of a fossil-fuel furnace or boiler is a measure of the amount of useful heat produced per unit of input energy (fuel). Combustion efficiency is the simplest measure; it is just the system’s efficiency while it is running. Combustion efficiency is like the miles per gallon your car gets cruising along at 55 miles per hour on the highway.

In the U.S., furnace efficiency is regulated by minimum AFUE (Annual Fuel Utilization Efficiency). AFUE estimates seasonal efficiency, averaging peak and part-load situations. AFUE accounts for start-up, cool-down, and other operating losses that occur in real operating conditions, and includes an estimate of electricity used by the air handler, inducer fan, and controls. AFUE is like your car mileage between fill-ups, including both highway driving and stop-and-go traffic. The higher the AFUE, the more efficient the furnace or boiler.

Boilers

Boilers are special-purpose water heaters. While furnaces carry heat in warm air, boiler systems distribute the heat in hot water, which gives up heat as it passes through radiators or other devices in rooms throughout the house. The cooler water then returns to the boiler to be reheated. Hot water systems are often called hydronic systems. Residential boilers generally use natural gas or heating oil for fuel.

In steam boilers, which are much less common in homes today, the water is boiled and steam carries heat through the house, condensing to water in the radiators as it cools. Oil and natural gas are commonly used.

Instead of a fan and duct system, a boiler uses a pump to circulate hot water through pipes to radiators. Some hot water systems circulate water through plastic tubing in the floor, a system called radiant floor heating (see “State of the Art Heating”). Important boiler controls include thermostats, aquastats, and valves that regulate circulation and water temperature. Although the cost is not trivial, it is generally much easier to install “zone” thermostats and controls for individual rooms with a hydronic system than with forced air. Some controls are standard features in new boilers, while others can be added on to save energy (see the “Modifications by Heating System Technicians” section on the heating maintenance page).

As with furnaces, condensing gas-fired boilers are relatively common, and significantly more efficient than non-condensing boilers (unless very sophisticated controls are employed). Oil-fired condensing boilers are uncommon in the U.S. for several reasons related to lower latent heat potential, and potential for greater fouling with conventional fuel oil.

Heat Pumps

Heat pumps are just two-way air conditioners (see detailed description in the cooling systems section). During the summer, an air conditioner works by moving heat from the relatively cool indoors to the relatively warm outside. In winter, the heat pump reverses this trick, scavenging heat from the cold outdoors with the help of an electrical system, and discharging that heat inside the house. Almost all heat pumps use forced warm-air delivery systems to move heated air throughout the house.

A ground-source heat pump heats and cools in any climate by exchanging heat with the ground, which has a more constant temperature.

There are two relatively common types of heat pumps. Air-source heat pumps use the outside air as the heat source in winter and heat sink in summer. Ground-source (also called geothermal, GeoExchange, or GX) heat pumps get their heat from underground, where temperatures are more constant year-round. Air-source heat pumps are far more common than ground-source heat pumps because they are cheaper and easier to install. Ground-source heat pumps, however, are much more efficient, and are frequently chosen by consumers who plan to remain in the same house for a long time, or have a strong desire to live more sustainably. How to determine whether a heat pump makes sense in your climate is discussed further under “Fuel Options.”

Whereas an air-source heat pump is installed much like a central air conditioner, ground-source heat pumps require that a “loop” be buried in the ground, usually in long, shallow (3–6' deep) trenches or in one or more vertical boreholes. The particular method used will depend on the experience of the installer, the size of your lot, the subsoil, and the landscape. Alternatively, some systems draw in groundwater and pass it through the heat exchanger instead of using a refrigerant. The groundwater is then returned to the aquifer.

Because electricity in a heat pump is used to move heat rather than to generate it, the heat pump can deliver more energy than it consumes. The ratio of delivered heating energy to consumed energy is called the coefficient of performance, or COP, with typical values ranging from 1.5 to 3.5. This is a “steady-state” measure and not directly comparable to the heating season performance factor (HSPF), a seasonal measure mandated for rating the heating efficiency of air-source heat pumps. Converting between the measures is not straightforward, but ground-source units are generally more efficient than air-source heat pumps.

Direct Heat

Gas-Fired Space Heaters

In some areas, gas-fired direct heating equipment is popular. This includes wall-mounted, free-standing, and floor furnaces, all characterized by their lack of ductwork and relatively small heat output. Because they lack ducts, they are most useful for warming a single room. If heating several rooms is required, either the doors between rooms must be left open or another heating method is necessary. Better models use “sealed combustion air” systems, with pipes installed through the wall to both provide combustion air and carry off the combustion products. These units can provide acceptable performance, particularly for cabins and other buildings where large temperature differences between bedrooms and main rooms are acceptable. The models can be fired with natural gas or propane, and some burn kerosene.

Unvented Gas-Fired Heaters: A Bad Idea

Gas or kerosene space heaters that do not have an exhaust vent have been sold for decades, but we strongly discourage their use for health and safety reasons. Known as “vent-free” gas heating appliances by manufacturers, they include wall-mounted and free-standing heaters as well as open-flame gas fireplaces with ceramic logs that are not actually connected to a chimney. Manufacturers claim that because the products’ combustion efficiency is very high, they are safe for building occupants. However, this claim is only valid if you keep a nearby window open for adequate fresh air— which defeats the purpose of supplemental heat. Dangers include exposure to combustion by-products, as discussed in Ventilation, and oxygen depletion (these heaters must be equipped with oxygen depletion sensors). Because of these hazards, at least five states (California, Minnesota, Massachusetts, Montana, and Alaska) prohibit their use in homes, and many cities in the United States and Canada have banned them as well.

Electric Space Heaters

Portable (plug-in) electric heaters are inexpensive to buy, but costly to use. These resistive heaters include “oil-filled” and “quartz-infrared” heaters. They convert electric current from the wall socket directly into heat, like a toaster or clothes iron. As explained further under “Selecting a New System,” it takes a lot of electricity to deliver the same amount of useful heat that natural gas or oil can provide onsite. A 1,500- watt plug-in heater will use almost the entire capacity of a 15-amp branch circuit; thus, adding much additional load will trip the circuit breaker or blow the fuse. The cost to operate a 1,500-watt unit for an hour is simple to compute: it is 1.5 times your electricity cost in cents per kilowatt-hour. At national average rates—12¢ kWh for electricity— that heater would cost 18¢ per hour to run—and quickly cost more than its purchase price. On the other hand, for intermittent use, it is the “least-bad” solution when alternatives would require major investments to improve ductwork for a specific area, for example. Just remember, electric resistance heat is usually the most expensive form of heat, and it is, therefore, seldom recommended.

“Electric baseboard heat” is yet another kind of resistive heating, similar to a plug-in space heater except that it is hard-wired. It has two principal virtues: the installation cost is low, and it is easy to install individual room thermostats so you can turn down the heat in rooms that aren’t being used. Operating costs, as for all resistive systems, are generally very high, unless the house is “super-insulated.”

Wood-Burning and Pellet Stoves

Wood heating can make a great deal of sense in rural areas if you enjoy stacking wood and stoking the stove or furnace. Wood prices are generally lower than gas, oil, or electricity. If you cut your own wood, the savings can be large. Pollutants from wood burning have been a problem in some parts of the country, causing the U.S. Environmental Protection Agency (EPA) to implement regulations that govern pollution emissions from wood stoves. As a result, new models are quite clean-burning. Pellet stoves offer a number of advantages over wood stoves. They are less polluting than wood stoves and offer users greater convenience, temperature control, and indoor air quality.

Fireplaces

Gas (and most wood) fireplaces are basically part of a room’s décor, providing a warm glow (and a way to dispose of secret documents), but typically not an effective heat source. With customary installations that rely on air drawn from the room into the fireplace for combustion and dilution, the fireplace will generally lose more heat than it provides, because so much warm air is drawn through the unit and must be replaced by cold outside air. On the other hand, if the fireplace is provided with a tight-sealing glass door, a source of outside air, and a good chimney damper, it can provide useful heat.

State of the Art Heating

Radiant floor heat generally refers to systems that circulate warm water in tubes under the floor. This warms the floor, which in turn warms people using the room. It is highly controllable, considered efficient by its advocates, and is expensive to install. It also requires a very experienced system designer and installer, and limits carpet choices and other floor finishes: you don’t want to “blanket” your heat source.

Ductless, Mini-Split, Multi-Split. Residential ductwork is relatively rare outside North America. “Ductless” heat pumps, which distribute energy through refrigerant lines instead of water or air, are widely used. Large field trials in the Pacific Northwest suggest that they can have good cold weather performance, and be very cost-effective where replacing electric resistance heating. Like ground-source systems, relative immaturity of the market helps assure that whole-house multi-split systems carry premium prices.

Combined heat and power (CHP) or cogeneration for houses is being seriously studied in some countries. The basic premise is to use a small generator to meet some of the electric demand of the house, and recover the waste heat (typically more than 70% of the heating value of the fuel) to heat the house (hydronic or water-to-air systems) and make domestic hot water. These systems are not yet widely available. They are likely to have the best economics in houses with high heating bills because the house cannot be feasibly insulated, such as solid stone or brick homes.

How To Avoid High Heating Repair Expenses

There are a few ways to maintain your furnace system. Odds are, during wintertime months your furnace runs all day trying to keep the home warm. In fact, it is probably on more than it needs to be because it is unable to maintain an efficient atmosphere. When troubleshooting and optimizing the heating portion of your furnace system, there are several things to consider.

Change The Air Filter

This is the part you typically hear people speaking about most often, but so few individuals take the recommendation and do anything about it. When there is a blockage, you either run the risk of not distributing heat appropriately or possibly igniting a fire.When the air filter gets dirty air will not flow through as well which suggests the furnace must work overtime and could also mean a likelihood of fire. If the system is not circulating heat properly, it will be working overtime. The fire issue is obviously self-explanatory. In each case it is not suitable for peace of mind or your budget.

Assess The Blower

Have a look at the blower blades to make sure they are free of crap. Should there be any build-up of dirt and dust, your fan will work overtime to blow the air around, and the heating will be overexerting itself. This means the system is overworking and costing more money to run.

Check To See That The Fire Damper Works

Next, look at the fire damper to make sure it is running properly. The fire damper explains itself so pay attention to this aspect.

Look For Holes In The Flex Duct

It is feasible that your ducts have become damaged throughout the years for different reasons. If a duct has collapsed or become blocked, your system will think that the right temperature has been achieved, which will not be true. Ultimately your equipment will be working harder to keep your home cool while you continue lowering the thermostat to get to comfortable settings.

Band Insulation

Insulation is usually missed but is perhaps the most regular reasons why an furnace system fails. Take the time to look at the insulation in between the duct work and the outside to make sure it has not worked itself loose. When this has happened furnace works more than wanted while trying to reach the best temperature.

Air Ducts Need To Be Sealed

See that the ductwork has not become separated from the next section. Disconnected ductwork will permit hot air to escape and of course add to the running costs.

Check For Leaks In The Return Air Inlets And Zone Dampers

Be certain to check that return air intakes are clean and in good shape or your system will be out of kilter. Examine the zone dampers to see if they are in the correct place. Through the year we could change the positioning of the damper for many reasons (i.e. getting into a tight space or arranging for storage). Check to see that the dampers are actually in the right position too.

If that is a little too much to handle by yourself, we propose you hire a local plumbing business certified for furnace and heating repair. You should manage to find a reputable heating company who can take care of this for you. For optimum results you could arrange annual upkeep for furnace and the heating people will call every year to take care of it.

How One Can Avoid High Heating Repair Expenses

There are a few ways to maintain your furnace system. Odds are, during wintertime months your heater is on all day trying to keep the house warm. furnace systems commonly run more than needed, because of incorrect settings. When trouble shooting and optimizing your heating segment of your furnace system, there are several things to examine.

The Air Filter

This subject is what gets referred to probably the most in talks about furnace maintenance, but is sometimes neglected. When there is a obstruction, you either run the chance of not circulating heat effectively or perhaps igniting a fire.When the filter becomes dirty air cannot flow through as well which suggests the unit must work overtime and will also mean a risk of fire. If the system is not circulating heat properly, it will be working harder. You want eliminate any likelihood of fire. In both cases it is not suitable for reassurance or your funds.

Test The Blower

Look at the blower blades to ensure they are clean. A messy fan will work overtime to blow air around and of course use higher energy to maintain the temperature level you choose it at. This means the system is overworking and costing extra money to run.

Fire Damper Function

Be sure to look at your fire damper for proper functioning. The fire damper is self-explanatory so take note of this factor.

The Flex Duct

It is feasible that your ducts became impaired throughout the years for a variety of reasons. If a duct has flattened or become blocked, the system will believe that the proper temperature has been achieved, which will not be true. When this happens the system works harder to do its job but will be unable to attain the right tempurature.

Make Sure The Insulation Is Secure

Insulation is usually ignored but is perhaps the most regular explanations why an furnace system malfunctions. Take the time to focus on the insulation between the duct work and the outside to ensure it has not come loose. When this happens furnace will work more than needed while trying to reach optimal temperature.

Air Ducts Need To Be Sealed

Make sure the ductwork is connected in all places to all sections. Disconnected ductwork will permit hot air leak out and of course add to the running costs.

Check For Leaks In The Return Air Inlets And The Zone Dampers

Check to see that return air intakes are free of debris and dust so air can easily flow. Look at your dampers to verify that they are in the best spot. Throughout the year we could change the position of the damper for a lot of reasons (i.e. getting in a tight space or arranging for storage). For a properly working system, look to see that the dampers are in the best place.

Why Heating Repair is Inescapable When Maintenance Is Forgotten

You can maintain an furnace system numerous different ways. Odds are, during winter months your furnace is on all day trying to keep the house warm. In fact, it is probably on more than it needs to be because it is incapable of maintaining an efficient climate. When trouble shooting and optimizing your heating segment of your furnace system, there are various things to check out.

The Air Filter

This subject is what gets talked about probably the most in chats about furnace maintenance, but is sometimes overlooked. When there is a obstruction, you either run the risk of not disbursing heat effectively or possibly starting a fire.When the air conditioner filter gets dirty air cannot flow through as well which means the unit must work overtime and will also mean a risk of fire. If the system is not circulating heat properly, it will be working overtime. You want eliminate any likelihood of fire. Neither scenario is good for your wallet or your well-being..

Test The Blower

Look at the blower blades and clean them up. A grimy fan will work overtime to blow the air around and of course use more energy to maintain the thermostat level you choose it at. This implies strain on your furnace system and your wallet since more fuel is required to continually run the blower.

Fire Damper Function

Next, look at the fire damper to ensure it is running correctly. The fire damper is self-explanatory so take note of this aspect.

Look For Holes In The Flex Duct

It is feasible that your ducts became impaired over the years for various reasons. If a duct has flattened or become stopped up, your system will believe that the proper temperature has been achieved, which will not be true. Finally your equipment will be working harder to keep your home cool as you continue lowering the temperature to reach comfy settings.

Make Sure The Insulation Is Secure

It is easy to overlook the insulation, but is one of the most typical reason behind a system malfunctioning. Take the time to focus on the insulation between the duct work and the exterior to make sure it has not come loose. If this has happened, your equipment will not reach ideal temperatures and will work too hard to attempt to accommodate.

Air Ducts Need To Be Sealed

Make sure the ductwork is hooked up in all places to all sections. These detachments may cause gaps in the air movement and cause a loss of hot air in your house, since it is going to be leaking out through the holes.

Return Air Inlets And Zone Dampers

Be certain to check that return air intakes are clean and in working order or your system will be out of balance. Check your dampers verifying they are in the right spot. Throughout the year we may change the positioning of the damper for a lot of reasons (i.e. getting in a tight space or arranging for storage). For a properly working system, check to see that your dampers are in the best place.

If this is a little too much to handle alone, we propose you hire an area plumbing business licensed for furnace and heating repair. You should be able to locate a good heating company who can manage this for you. The best advice we can provide is to set up annual maintenance for this appliance.

You can maintain an furnace system a number of different ways.

When a furnace works too much, it costs more to run. The fire issue is self-explanatory. In both cases it is not suitable for reassurance or your finances.

This means strain in your furnace system and your wallet since more gas is required to continually run the blower.

Fire Damper Function

Next, look at the fire damper to make sure it is running acceptably. This will ensure that the risk of fire is reduced and the system works more efficiently.

Heating Repair And Seasonal Maintenance Tips

You can maintain an furnace system a number of different ways. Chances are good the system will be running full-time in winter. In fact, it is usually on more than it needs to be because it is incapable of maintaining an operable environment. There there are various areas in the heating section to take a look at when troubleshooting for proficiency.

The Air Filter

This subject is what gets brought up the most in discussions about heating maintenance, but is usually neglected. When there is a obstruction, you either run the chance of not circulating heat properly or perhaps igniting a fire.When the air filter becomes dirty air will not flow through as well which means the furnace must work overtime and could also mean a likelihood of fire.

Check To See That The Fire Damper Works

Be sure to look at your fire damper for proper functioning. This will ensure that the fir risk is minimal and the system works more efficiently.

Look For Holes In The Flex Duct

Air ducts get bumped into over the years. If a duct has flattened or become stopped up, the system will think that the proper temperature has been achieved, which will not be true. Inevitably your system will be straining to maintain your house cool while you continue lowering the temperature to get to cozy conditions.

Be sure to check the insulation and validate it has not become unfastened and caused gaps between the ductwork and the exterior. If this happens, your system will not reach optimal temperatures and work overtime to attempt to accommodate.

Ductwork Needs To Be Connected

See that the ductwork has not become separated from other sections. These detachments may cause spaces in the airflow and result in a loss of hot air in your house, since it will be getting out through the spaces.

Be sure to check that return air intakes are dirt free and in good condition or your system will be out of kilter. Check your dampers verifying they are in the best position. Throughout the year we may change the position of the damper for a lot of reasons (i.e. getting into a tight space or making room for storage).

How To Repair Fan Coil Breakdown: What You Need to Know?

With the onset of the cold season, the correct operation of the fan coil in your home becomes important. This is especially important if you have small children or someone in your family is in poor health. However, any technique has the ability to break and this can happen at any time, regardless of how much you need it at the moment. Repair fan coil breakdown is urgent if you want your health to be safe. If you do not deal with technology in your professional activity, then it may seem to you that this is a very complex system, but probably every adult can understand the concept of its work. If you know the principles of fan coil operation, then perhaps in some cases you will be able to avoid the expensive repair fan coil breakdown or even its complete replacement.

Why fan coils are so popular

There are various models and versions of fan coil units from different companies, but the concept of their functioning is quite simple and similar in different versions. The reason this type of air conditioning is so common in homes throughout US is its lower cost compared to other types of air conditioners. Fan coil is universal due to its simplicity. It is used in heating, air conditioning and home ventilation systems. The principle of its operation is based on heat transfer between liquids. Depending on whether you want to heat or cool the room, the fan coil passes cold or hot water through its coil, and the fan creates an air stream. Due to this, heat transfer occurs in the coil tubes, then fan coil is a simple heating or cooling device. Similar processes take place in your refrigerator or in your car motor with coolant, but fan coils have the ability to work in both directions, so they are universal in their application. Units with two pipes at the same time can work only in one direction - either heat or cool the room. If you need to maintain a different microclimate in some room, then you will need a fan coil with four pipes, which can work both for cooling and heating. Some models have manual control, others will adjust the temperature you set automatically. Also, fan coils will differ in power and installation location. According to the installation method, fan coils are divided into three main types: Horizontal ceiling devices. Often they are installed under the ceiling in a return grill. Vertical fan coils. They are mounted against a wall and are usually designed to control temperature in only one room. Vertical cabinet. Designed for installation in a separate utility room with access to the outdoor. The price will depend on all these parameters when buying a new fan coil, as well as when repairing an old one. Repair fan coil breakdown in some cases can be expensive, but when it's cold outside it needs to be done quickly. In cases where the repair fan coil breakdown came at a late fall, and you don’t have any savings or you don’t have them enough, you may need to seek financial support and take a quick online loan welcome so as not to expose your health and the health of your family members in danger.

Common Problems with Fan Coil Units

Let’s now find out what are the main problems leading to the need for a repair fan coil breakdown. Knowing the main reasons for the failure of fan coils, you will be able to timely notice emerging problems and take measures that will not allow more serious breakdowns to occur.

Air flow

Fans in fan coils are designed for a specific air resistance. If this indicator increases, then the fan will not work efficiently, and also being under increased load will wear out faster. Without giving the required amount of air, the fan coil will not be able to properly heat or cool the air in the room. Why can air resistance increase? The reasons may be different, but most often these are dirty filters and air ducts and coils. Also, an inappropriate duct configuration for a fan of a certain power can create additional resistance.

Cooling problems

To cool the rooms, fan coils must distribute water of a given temperature from the chiller over long distances. Often water is supplied at a different temperature or in an inappropriate design volume. This may result in reduced room cooling performance. There is a big risk that the central unit will not be able to overcome water shortages or exceed the required temperature. In the worst case, the fan coil will need to be replaced. A more powerful fan, more cooling rows, different coil schemes - each of these parameters can be amplified, which will bring a positive result.

Increased noise

One of the tangible disadvantages of this method of adjusting the air temperature is the noise level. In general, they are not so loud, but for a person who is not used to them, some fan coil units are noticeably noisy. This does not apply to all devices, since it often depends on the specific components. Replacing such components eliminates this drawback. The required air volume will be achieved at lower speeds when replacing the old fan. Most fan coils are designed for high speed. In order to help the performance, the fan must be designed for a lower speed, but with a large number of cooling rows, which will eliminate the noise problem. It is possible to install silencers in the air ducts, but they in turn add air resistance, so you will also need to replace the fan with a more powerful one.

Other breakdowns

There is a possibility of leakage of water or other liquids, as it is used in the system. In addition, these liquids, as well as water, can lead to increased corrosion of the metal parts of the coil. A fan coil will never be able to function properly without the connection between pipes and fins providing heat transfer. The connection between the rib and the pipe is a key feature in the coil. With constant expansion and contraction, the connection of the ribs with the pipe becomes less effective over time. Also, the device is a mechanical and electrical system, so various mechanical or electrical problems are possible that will require a repair fan coil breakdown. Sometimes fan coils can just freeze. It is worth monitoring the cleanliness of the air ducts and the condition of the filters, changing them in a timely manner so as to prevent clogging of the coil. In general, component replacement may require financial assistance when you need to apply for a loan to solve problems with fan coil breakdown. If the coils are chosen correctly, then most of them can serve for decades, provided that they are properly maintained. The service life is affected by the conditions in which fan coils operate, such as air quality and water quality, routine maintenance. Timely cleaning of finned surfaces allows you to delay the repair fan coil breakdown for the longest possible time and increase the efficiency of the entire device. As a result, having paid for a qualified fan coil service now, you save your money in the future. Always use special cleaning products, as many of them corrode aluminum fins, which adversely affects the fan coil performance. Corrosion of a rib reduces its thermal conductivity, while degrading the fan coil's performance. Corrosive liquids, high temperature and pressure do their job, gradually destroying the coil from the inside, reducing the heat transfer that underlies the fan coil.

The Most Common Types of Repair Fan Coil Breakdown

Depending on the initial quality of the fan coil from the manufacturer, on the conditions in which it operates and on maintenance during the entire service life, this period will also depend. In some cases, the fan coil can last up to 30 years. However, during this period you will still have to repair it several times. In some cases, it may be better to immediately replace with a new fan coil, which in the end will cost you less. These types of repair fan coil breakdowns are most often encountered by homeowners or tenants, and often make mistakes trying to solve the problem on their own. High pressure cleaning seems like a great way to quickly remove dirt from the fins of a coil, but remember that high pressure can bend thin aluminum fins and increase air resistance. This will reduce the performance of the coil, and can also clog the core of the coil, which is very difficult to clean. A coil failure indicates that your fan coil is leaking. High pressure in the system found its way out there, the tube is weakened and the system is no longer sealed. Re-soldering in the same place. If you find the place where the system lost its tightness and sealed it, then soon you will have to solder the coil again. The system has ceased to be sealed due to the fact that erosion inside the tube has already significantly weakened it and soon there will be a gap again. Removing the leaking tube from the circuit. It would seem that you solved the leakage problem by removing the tube damaged by erosion or corrosion, but by doing so you greatly reduced the area for heat transfer, thereby reducing the heating or cooling efficiency. Such a repair fan coil breakdown solution is temporary and only makes sense for the coil to work until it is replaced as soon as possible. For effective operation, the fan coil will have to spend more energy, which will create a gap in your budget through which your money will flow out.

Save your money

Repair fan coil breakdown of course you need to do to stay in a warm house in the winter and in a cool house in the summer, in case you do not have available funds now to replace your old fan coil with a new one. So that after the repair fan coil breakdown it does its work at the required level, you will need to configure it differently so that you can pull your home temperature back to normal. You can add the temperature in the boiler, increase the fan speed or adjust the temp in the cooler to achieve the desired effect. In general, this will somehow work, but it is better to reduce the work of the fan coil in this mode to a minimum. Such work will constantly increase energy costs and, accordingly, you will need more electricity to maintain the previous level. Your electricity bills will grow until you have a major repair fan coil breakdown or replace it with a new one. Repair will not solve the problem at all, but will only have a temporary effect. You will pay for it, then additionally for electricity, all the same, everything will end with the replacement of the fan coil. Of course, it can be difficult for your monthly budget to find money quickly for such unplanned expenses, but you can apply for financial support from lenders by applying for a quick loan online. This one might be a good solution for repair fan coil breakdown so you don’t overpay anymore. Read the full article

Rotary Vacuum Evaporator - The Most Versatile Borosilicate Glass Process Equipment

A Rotary Evaporator, also popularly known as a Rotavapor or Rotovap, is a specialized and extremely Versatile Equipment for chemical processes.

In this Article, we would touch upon the following broad topics:

Rotary Evaporator Principle

Rotary Evaporator Construction

Rotary Evaporator Design Variations

Rotary Evaporator Applications

Other Evaporation Alternatives to Rotovap

1) Rotary Evaporator Principle

The Evaporator is essentially working on the same principles as a distillation unit i.e. separation of components having different boiling points. However, few special design features make the functioning of the Rotovap unique and versatile.

Operation under high vacuum of 1 torr, thereby reducing the solvent boiling points under vacuum considerably as compared to the boiling point under atmospheric conditions.

Constant rotation of Rotary flask results in a thin layer of process media on the inner wall, thereby ensuring uniform heating across the entire mass, and less possibility of bumping.

The rotation of flask immersed in the bath increases the surface area of evaporation greatly, thereby increasing the speed of distillation.

The rotation mechanism also makes it suitable for volatile and heat-sensitive process media, wherein the properties can alter if direct high heat is applied for longer time. This is because due to rotation, the process feed is evenly mixed.

Plug and Play type of construction making it easy to switch the configuration for different applications.

The Rotary Evaporator is normally always operated under high vacuum. The Feed is charged inside the rotary flask from the feed tube made of PTFE.

Ideally, feed up to a maximum of 70–80% capacity of the rotary flask is desired for optimum results. Once the feed is charged, the rotation is started.

Also, the utility circulation in the condenser is started. This rotation action creates a thin film of process feed on the wall of the rotating flask.

Next the heating is started. The rotary evaporator procedure is very crucial for efficient performance. Once the oil in the bath starts heating, and this heat is indirectly passed to the process feed inside the flask.

As the process feed gets heated, the low boiler converts into vapours, and goes up the vapour tube and into the condenser, where the condensate is formed.

This condensate can either be refluxed back into the rotary flask for higher purity applications, or collected in the receiver.

Depending on the design features, a lot of different process possibilities are there, but the basic operating principle essentially remains as indicated above.

2. Rotary Evaporator Construction

The Main Components of a Standard Rotary Evaporator are enlisted below:

The water/oil bath is a heated bath which encloses the main rotary flask and is used to indirectly heat the contents of the process.

The bath is usually equipped with electric heaters which can be ATEX-compliant or weather-proof, depending on the application area’s Hazardous Zone Classification.

As a safety feature, the bath is appropriately insulated so that the outside surface is not too hot to touch.

The Rotary Flask is the main component where the process fluid is initially charged, and is made of Borosilicate Glass 3.3 raw material.

The Flask’s construction is of prime importance for the smooth rotation along the central axis.

Our advanced manufacturing techniques ensure that the evaporating flask is rotating perfectly along the central axis, thereby ensuring that the entire surface area comes in contact for the same time with the heating media in a bath.

The Mechanical Seal, along with the motor unit connected to the flask is responsible for the smooth and leak-proof rotation of the flask at a constant speed.

An RTD is placed just above the vapour tube to measure the vapour temperature before it goes into the condenser.

The RTD is inserted inside the vapour tube in a glass thermowell. This ensures that the contact parts are strictly Borosilicate Glass 3.3 and PTFE only and the metal tip of PT-100 sensor does not come in direct contact with the process vapour.

A Shell & Coil type condenser of suitable heat transfer area is chosen so that there is no pressure build-up due to excessive un-condensed vapours.

The condenser is preferably placed in vertical orientation for efficient condensation.

Different configurations with single and double condensers are available depending on the application. As a standard, a single condenser is provided.

A vent is provided at the top of the condenser. This can be used for venting in the case of excessive pressure build-up.

We can also connect the vacuum pump here. Alternatively, the vacuum pump connection can be made at the receiver vent nozzle.

All such vent outlets are equipped with suitable valves with leak-proof PTFE bellow to glass connections.

The vent valve is provided with GL18 thread at the end, where BOLA connectors can be placed and hose pipe connected.

This arrangement provides seamless connection without any leakages.

The Liquid feed is used to feed the process feed into the rotary flask without breaking the process vacuum.

Since the system is already under vacuum, the process feed easily flows into the system.

This valve too is provided with GL thread and BOLA connector. This valve is connected with a PTFE tube which travels throughout the vapor tube, directly into the rotary Flask.

This ensures that the feed does not get carried to the receiver directly along with the vapour or condensate flowing in the vapour tube.

A Product Cooler is essential to cool down the condensate, before moving it to the receiver.

The product cooler is essentially a Shell & Coil type heat exchanger with the process fluid in the coil side and utility in the shell side.

This arrangement ensures rapid cooling in a short time.

The receivers are spherical vessels with multiple nozzles of a suitable size. The units usually have either one or two receivers, connected in parallel.

The receiving vessel has a short drip tube to ensure that the solvent drops down directly into the vessel and not flow along the walls.

A Control Panel is an integral part of the Rotary Evaporator. This is a highly customized part and Ablaze can offer partial to full automation of the process through the control panel, depending on the client’s process requirement.

As a standard, the basic model has provision for digital display of Bath temperature, Vapour Temperature and RPM of the Rotary Flask. It also has controls to set the desired RPM and the desired Oil Bath Temperature.

In a little advanced models, Vacuum control and monitoring is also provided, wherein the vacuum pump is connected via the panel and the required process vacuum can be set, monitored and controlled directly through the panel.

Further customization and control can be provided, since we have a highly advanced in-house automation team.

The Panel and all the electric components are housed in an ATEX-Compliant Enclosure for operation in hazardous areas.

The Entire Rotary Evaporator System is mounted on a Compact Skid of Stainless Steel where all the components rest and all provided appropriate support to ensure vibration free operation.

This skid itself is mounted on heavy duty Castor Wheels, which can be locked, to provide easy movement of the unit in the plant or lab.

A Safety Lid is placed on the rotary flask as a precaution in case of spillage risk. It is transparent and hence it provides safety without compromising on the reaction visibility.

3. Rotary Evaporator Design Variations

Multiple Design Variations are available in Our Standard Rotary Film Evaporator to suit different process needs. Some of the standard design variations are:

Dual Receivers

This configuration allows continuous drain without breaking the process vacuum. The two receivers are connected in parallel so that at any given point of time, the condensate is being collected in one of them.

Once this receiver is full and needs to be drained out, the valve above it is closed, and the condensate is taken in the second receiver.

This way, the system vacuum is not disturbed during draining.

Dual Condensers

This design is used when immediate condensation of the vapours is required. Two condensers are placed in parallel, and the condensate is directly collected in the receivers.

This ensures 100% solvent recovery. This design can also be modified for continuous operation.

ATEX-Compliant

The Rotavap contains a lot of electric components — two sets of drive (one for rotation and other for bath lifting) and a control panel.

We do understand that a lot of applications require the Rotovap to be used in Zone 0 / 1 / 2 hazardous classified area and hence we have a model with all electrical components and connection which comply to these stringent requirements.

Multiple MOCs

The contact parts with process media are strictly Borosilicate Glass 3.3 and PTFE. However, the couplings, skid etc do not come in contact with the process media and can be offered in various MOCs (Material of Construction) such as Stainless Steel grade 316 or 304, Mild Steel, etc.

The couplings can also be made of Bakelite to provide good resistance to corrosion in case the environment has exposure to corrosive gases. The fasteners can be PTFE coated to improve their life.

4. Rotary Evaporator Applications

The wide array of applications where a rotovap can be used shows how versatile the equipment is. It finds application in the following processes:

Distillation (Continuous and Discontinuous)

Concentration

Solvent Recycling

Solvent Evaporation and Recycling

Reflux Process Reactions

Component Drying

Component Purification

Fine Chemical Synthesis

Crystallization

Molecular Cooking

5. Other Evaporation Alternatives to Rotovap

There are few other Process Equipments which have similar functionality as Rotary Evaporator and are used specially for Evaporation.

1)Falling Film Evaporator

A Falling Film Evaporator is essentially similar to a Vertical Shell & Tube Heat Exchanger in construction. The process fluid enters the evaporator from top and flows in a thin film along the walls of tubes. The same is instantly converted into vapour by the hot utility flowing in the shell. This Evaporator is completely custom designed as per the process requirement.

2)Wiped Film Evaporator

A wiped Film Evaporator is essentially a thin film Evaporator (TFE) just like a rotovap. It works on the principle of the thermal separation of products in a mechanically generated, thin and highly turbulent liquid film along the outer surface of the evaporator.

Having worked on Rotary Evaporators for over 20 years, we have various case studies of their application in non-traditional applications as well. So if you require a rotary evaporator or have any process with which you need assistance, do reach out at [email protected]

Systems For Accommodation Area Of A Ship You Must Know About

Accommodation of a ship is the living space where cabins for ship’s crew are located, along with galley, provision stores & refrigeration, messrooms, recreational rooms, gymnasium, meeting rooms, lockers, etc.

The accommodation area is supported by water supply, sewage system, air condition system, fire safeties, etc. These systems are very different as compared to the conventional ones found in residential buildings on the land.

In this article, we will take a look at all important systems for the accommodation areas of a ship:

Domestic Fresh Water System

Freshwater in the domestic freshwater system onboard may be taken from shore or produced onboard. The freshwater generator produces water for use in the domestic freshwater system on the ship.

This distilled water produced by freshwater generator passes through a mineraliser (hardening filter) to reduce acidity and increase the mineral content of the water before directed to one of the freshwater storage tanks.

If distilled water is required directly is for boilers, the mineraliser is bypassed.

A silver ion steriliser is supplied to destroy bacteria and leave silver ions in the stored water, providing effective sterilisation whilst the water is stored.

Normally one domestic freshwater FW tank is in use, with the second being filled or ready for use, as standby.

youtube

Steriliser

Steriliser onboard can mainly be of two types – silver ion steriliser or ultraviolet steriliser.

The silver ion steriliser is operated to treat water already in the freshwater storage tank. The hydrophore unit draws water from one of the freshwater storage tanks and passes it through the steriliser unit.

The water then passes between the electrodes and silver ions are introduced, producing a concentrated sterilising solution. This solution is then introduced into the selected freshwater storage tank as required.

The concentration is such that when diluted, the residual level of the silver ions in the tank remains toxic to the bacteria. If the water remains in the tank for an extended time, it may become necessary to retreat and restore the required ion balance.

Note: Samples of the water in the storage tanks, the supply system and the steriliser should be taken and analysed at regular intervals, as recommended by the manufacturer.

The ultraviolet sterilizer is a device that carries out the sterilization of water instantaneously by using ultraviolet rays. Accordingly, it does not have a remaining effect like that of chlorine sterilization. It consists of a quartz tube, a germicidal lamp and a water filter.

The germicidal lamp emits ultraviolet rays to kill the germs in the water. Never see the germicidal lamp with naked eyes, since the powerful ultraviolet rays can be harmful.

Mineraliser

Mineraliser or rehardening filter is designed to treat distilled water from the freshwater generator, producing water that is more suitable for human consumption.

Mineraliser consists of dolomite stones. As the water passes through the mineraliser, acidic components are neutralised by reaction with calcium and magnesium salts in the dolomite, resulting in an improved pH, this should be between 7.5 and 10 (This can be adjusted by increasing or reducing the quantity of dolomite in the filter).

A part of the dolomite is dissolved in the water, supplying necessary mineral salts and hardness. Domestic freshwater for general use is stored in two freshwater tanks, ports and starboard.

There are generally two freshwater hydrophore pumps (one running and other standby), which draw from the freshwater tanks and delivers to the hydrophore pressure tank, which is provided with an air cushion, topped-up from the working air system.

The pressure in the hydrophore tank controls the starting and stopping of the hydrophore pumps. As the water is consumed, the tank pressure drops, which automatically starts the selected pump and refills the tank.

When the pressure increases to a predetermined value, the pump will automatically stop. One pump is normally in use, with the second pump shutdown or ready for use.

From the hydrophore tank the water flows into three systems:

Domestic cold-water system and accommodation services

This system covers the water supply to drinking water fountains and the accommodation for use in cabins, pantries and the galley.

Domestic hot water system

This system supplies continuous hot water to the accommodation for domestic purposes. Water is circulated continuously by the hot water circulating pump, passing through a calorifier, where it is heated by either steam or electrically to the correct temperature.

Topping-up of the system is from the hydrophore tank. This arrangement of constant water circulation ensures that hot water is available at an outlet immediately as a tap is opened and reducing waste due to cold water flowing until hot water is available.

Engine room and deck service system

This system supplies to deck freshwater hose connections, engine room freshwater hose connections, and many other places in the engine room where freshwater is required, for e.g. filling connection for expansion tank, filling connection for chemical dosing tanks, generator turbocharger water washing connection, stern tube seal unit, bilge oily water separator and so on.

Domestic Refrigeration System

There are three refrigerated chambers where all the provision food is stored, namely vegetable room, meat room and fish room.

The refrigeration plant is automatic in operation and consists of two reciprocating type compressors, two condensers with an evaporator coil/fan unit in each of the three refrigerated chambers (meat, fish and vegetable rooms).

Cooling for the meat, fish and vegetable rooms is provided by a direct expansion R134a system. Liquid R134a refrigerant is passed to the evaporator coil for the room and the expansion valve regulates the amount of liquid flowing to the evaporator in accordance with the gas outlet temperature; if the temperature has risen, more refrigerant passes to the evaporator.

The liquid expands to the gas stage in the evaporator coil by extracting heat from the air in the refrigerated chamber. The air in the cold chamber is circulated over the evaporator coils by an electrically-driven fan.

The supply of refrigerant to the expansion valve is regulated by means of a temperature-controlled solenoid valve in the supply line.

The refrigerated room evaporator is equipped with a timer-controlled electric defrosting element. The frequency of defrosting is chosen by means of a timed defrosting relay built into the starter panel.

Under normal conditions, one compressor/condenser unit is in operation, with the other ready for manual start-up, with all valves shut until required.

The system is not designed for parallel operation of the compressor units and the valve on the compressor unit, which is out of service, must be fully closed.

The compressor draws R134a vapour from the cold chamber evaporators and pumps it under pressure to the condenser where it is cooled by water circulating from the central cooling FW system.

The gas is condensed under pressure into a liquid. The compressors are protected by high pressure, low pressure, low lubricating oil pressure, and condenser cooling water failure cut-out switches.

The liquid refrigerant passes through a filter/dryer to the cold room evaporators.

Thermostats in each chamber enable temperature controllers to operate the solenoid valves independently so as to reduce the frequency of compressor starts and running time.

The evaporators accept the refrigerant as a super-cooled vapour from the expansion valves. The opening of the expansion valve is regulated by the refrigerant gas temperature at the outlet from the evaporator.

This vapour extracts heat as it passes through the evaporator but is still colder than the liquid stage. The cold vapour then returns to the compressor, passing through the heat exchanger where it cools the liquid refrigerant further.

The solenoid valves at the air coolers (evaporator units) are opened and closed by the room thermostats, allowing refrigerant gas to flow to the evaporator when open. With the solenoid valves closed, no gas flows to the evaporators and so no gas flows back to the compressor suction. The low-pressure switch will stop the operating compressor.

Any leaks of refrigerant gas from the system will result in the system becoming under-charged. The symptoms of the system under-charged will be low suction and discharge pressures with the system eventually becoming ineffective. Bubbles will appear in the liquid-gas flow sight glass.

When required, the additional refrigerant can be added through the charging line, after first venting the connection between the refrigerant bottle and the charging connection in order to prevent any air or moisture in the connection pipe from entering the system.

The added refrigerant is dried before entering the system. Any trace of moisture in the refrigerant system will lead to problems with the thermostatic expansion valve icing-up and subsequent blockage.

The meat and fish room operating temperatures are -20°C and the vegetable room operating temperature is +4°C. The temperatures in the chambers are regulated by means of the room thermostats which activate the associated solenoid valve supplying gas to the air cooler/evaporator.

Accommodation Air Conditioning System

The air is supplied to the accommodation by an Air Handling Unit (AHU) located in the air conditioning unit room. The AHU consists of an electrically-driven fan drawing air through the following sections from the inlet to the outlet:

• One air filter • One steam preheating unit • One enthalpy exchanger • One reheat section • Two air cooler evaporator coils • A humidifier section • A water eliminator section • A fan section • A discharge section

Humidification of the air is arranged with automatic control and this is fitted at the outlet section of the AHU. The air is supplied through the distribution trunking to the accommodation. Cooling is provided by a direct expansion R134a system.

The plant is automatic and consists of two compressor/condenser units supplying the evaporators contained in the accommodation air handling unit. The expansion valves for the coils are fed with liquid refrigerant from the air conditioning compressor, the refrigerant having been compressed in the compressor, then cooled in the condenser where it is condensed to a liquid.

The liquid R134a is then fed, via the filter dryer, to the evaporator coils where it expands under the control of the expansion valves, before being returned to the compressor as a gas. The phase change (liquid to gas) takes place in the evaporator coils where it extracts heat from the air passing over the outside of the coils.

The compressors are fitted with an internal oil pressure activated unloading mechanism which affords automatic starting and variable capacity control of 100%, 75%, 50% and 25% of full capacity by unloading groups of cylinders.

This variable capacity control allows the compressor to remain running even when the load is relatively light and thus avoids the need for frequent stopping and starting.

The compressor is protected by high and low-pressure cut-out switches, a low lubricating oil pressure trip, a cooling water pressure trip, and high pressure and oil supply pressure differential trip.

A crankcase heater is provided for use when the compressor is not running.

Any leakage of refrigerant gas from the system will result in the system becoming under-charged. The symptoms of the system being under-charged will be low suction and discharge pressure and the system will eventually become ineffective.

A side effect of the low refrigerant gas charge is apparent low oil level in the sump. A low charge level will result in excess oil being entrapped in the circulating refrigerant gas, causing the level in the sump to drop.

When the system is charged to full capacity, this excess oil will be separated out and returned to the sump. During operation, the level as shown in the condenser level gauge will drop.

If the system does become under-charged, the whole system pipework should be checked for leakage. The only reason for an under-charge condition after operating previously with a full charge is that refrigerant is leaking from the system.

When required, additional gas can be added through the charging line, after first venting the connection between the gas bottle and the charging connection. The added refrigerant is dried before entering the system.

Any trace of moisture in the refrigerant will lead to problems with the thermostatic expansion valve icing-up and subsequent blockage. Cooling water for the condenser is supplied from the low-temperature central freshwater cooling system.

Air is circulated through ducting to outlets in the cabins and public rooms. The airflow through the outlets can be controlled at the individual outlets.

Sewage Treatment Plant

Sewage (black water) from the accommodation spaces is drawn by gravity or by vacuum through the pipe system to the ejector on the sewage collection tank.

The vacuum in the system is maintained by circulating fluid from the collection tank through the ejector. The sewage in the collection tank is discharged to the sewage treatment plant located in the engine room.

A sewage treatment plant is a biological unit which works on the aerobic activated sludge principle. The plant will treat black and grey water and is fully automatic in operation.

Air is supplied to the sewage treatment unit by an independent aeration blower. This sewage treatment plant consists of a tank with four main compartments:

Bioreactor with matrix (aeration compartment)

The sewage in this compartment is from the lavatory pans, urinals and hospital in the accommodation spaces. The incoming effluent material passes through a screen to prevent the passage of inorganic solids into the bioreactor compartment, where it mixes with the activated sludge already present.

The passage through the vacuum system breaks down the raw sewage into small particles which mix easily and encourage bacterial action.

The matrix unit in the compartment ensures movement of the effluent and rapid biological breakdown of the raw sewage by the bacteria present. Air is supplied by means of a blower and distributed evenly through the tank by aerators.

The gas produced during the bacterial action which takes place is vented to atmosphere at the funnel top. Oxygen from the air is essential for the aerobic activity of the bacteria.

These organisms require oxygen for digesting the raw sewage and it also assists by agitation and mixing the incoming sewage with the water, sewage sludge and bacteria already present in the compartment.

Settling or clarification compartment

Effluent from the bioreactor compartment flows to the sedimentation tank compartment where sludge is separated by gravity.

The sludge is then returned to the bioreactor compartment screen section by means of an airlift supplied with compressed air from the aeration blower.

The effluent then passes into the bottom of the filter tank.

Filter compartment

The activated carbon filter in this chamber breaks down any remaining micro-organisms and filters out any solid material.

Air is supplied by means of the blower and distributed evenly through the tank by the aerators at the bottom.

The filter requires backflushing with steam every month. The clean effluent flows from the filter compartment into the sterilisation compartment.

Clean water sterilisation or discharge compartment

This compartment is provided with float operated switches which activate the discharge pump when the high level is reached and stop the pump when the compartment is nearly empty.

Sterilisation of the treated effluent is chlorination with sodium hypochlorite by means of a chemical injection pump or by manually adding chlorine tablets.

The sewage treatment plant works automatically once it is set, but periodic attention is required, and the unit must be monitored for correct operation.

The treatment plant discharge pump may be set to discharge overboard, into the double bottom sewage collecting tank or to the port and starboard deck connections for discharge to shore. The sewage collecting tank is either pumped in the same manner.

Garbage Disposal System

Annex V of MARPOL 73/78, the Regulations for the Prevention of Pollution by Garbage from Ships, controls the way in which waste material is treated onboard ships.

The regulations require the vessel to have a Garbage Management Plan in place. The plan should outline the procedures for handling, segregation, storage and subsequent disposal of the vessel’s generated garbage.

The plan is to be clearly displayed in locations used for the handling of waste and name the person on board responsible for the plan management.

Although it is permissible to discharge a wide variety of garbage at sea, preference should be given to disposal utilising shore facilities where available. A summary of the garbage disposal regulations is given next.

The special areas are as follows:

• The Mediterranean Sea. • The Baltic Sea. • The Black Sea. • The Red Sea. • The Persian Gulf. • North-West European Waters. • The Gulf of Aden. • The Antarctic. • The Wider Caribbean Area.

Food waste ONLY is permitted to be disposed of inside a special area, but not less than 12 miles offshore.

Every ship has to have a standard Garbage Management Plan which outlines the responsibilities of crew members and the location of all the garbage bins and collection area.

Fire Fighting In Accommodation

At various places including inside each cabin, smoke detectors are present to detect smoke from the fire. Each deck consists of portable fire extinguishers DCP type usually two in number, one port side, and one starboard side.

Fire hydrants and fire hose are present outside on the deck wings on each deck. Galley has a separate fire extinguishing system of its own.

Galley CO2 Fire Extinguishing System

The galley exhaust duct has a local CO2 system consisting of a single CO2 cylinder which is located in a small compartment adjacent inside the galley.

It provides an extinguishing capability in the event of a fire in the galley and galley exhaust duct. In the case of fire, switch off the galley fans and close the uptake fire damper in the galley deckhead.

The emergency stop switch for the galley fans should be located outside the galley, and also on the bridge and in the fire control station.

Evacuate all personnel from the galley, then release the CO2 cylinder by opening the cylinder storage door and opening the cylinder outlet valve fully. Exit from the galley and close the galley entrance door.

Some of the galleys are also equipped with deep fat fryer wet chemical extinguishing medium for a deep fat fryer. Fat fryers are particularly difficult to protect due to the amount of stored heat that is contained in a large quantity of cooking oil.

The deep fat fryer appliance in the galley is protected by a fixed fire suppressant system. The protection system is comprised of a single stainless-steel storage cylinder containing an extinguishing agent.

The cabinet is located in the galley and is activated by pulling a release handle located close by the system cabinet.

When activated, the chemical extinguishing agent is discharged into the fire extinguishing pipework. The discharge from the cylinder is led via piping to fixed spray nozzles. The extinguishing chemical has an expected storage life of twelve years.

The extinguishing wet chemical used is R-102 Ansulex Low pH Liquid Chemical.

Other Safeties In Accommodation

All the lockers and cabins in the accommodation are provided with door locks. These door locks have their individual keys and can also be opened by a master key which will be in custody of the Master.

The stairways have anti-skid stripes to prevent tripping and falling and also handrails for support. Handrails are also provided along alleyways each deck for support during rolling and pitching.
