Air conditioning is refrigeration: the removal of heat from the air. Almost all forms use evaporation, the process by which a liquid turns to a gas and in the process absorbs heat energy.
Two of the major forms of cooling are:
Evaporative Cooling
Water is allowed to evaporate on a surface, absorbing heat. This is used in "swamp coolers" and in commercial "chillers" that work with mechanical refrigeration.
Mechanical Refrigeration
A liquid refrigerant (generically called freon) is circulated through a chamber where it is allowed to expand. This expansion causes liquid to evaporate into gas as the molecules absorb heat. The gas is then mechanically compressed to a liquid again, where it loses its heat outside the system. (Household refrigerators transfer this heat through coils to the kitchen air, while window and central air conditioners release their heat outdoors.)

Thermoelectric Cooling
Small portable coolers can also use electrically-driven coolers that create a heat flux to withdraw energy as electric current, albeit inefficiently.
What else can I help you with?
What energy transformation is use for air-conditioning?
Air conditioning involves the transformation of electrical energy into thermal energy. The electrical energy is used to power the air conditioning unit, which then removes heat from the indoor air, cooling it down.
What year did WH Carrier invent air conditioning?
Willis Haviland Carrier invented air conditioning in 1902.
Why air con was invented?
Air conditioning was invented to control the humidity and temperature in indoor spaces, making them more comfortable for occupants. It was initially developed for a printing press in 1902 to improve the quality of printed materials by controlling the temperature and humidity. Since then, air conditioning has become essential for maintaining comfortable living and working environments in a wide range of climates.
Does the air conditioning blow colder when the temperature is set lower?
Yes, the air conditioning blows colder when the temperature is set lower.
How are air compressors different from air conditioning compressors?
Air Conditioning compressors always use in the home, it is small and cheap price, In generally, we think that air compressor is industrial air compressor, which this kind of air compressor use in factory and mining machinery, to compressed air.
How does air conditioning relate to physics?
The motors inside an air conditioning module have to rotate and create gust, or wind, which is part of pascal's principle.
Rear air conditioning not working 2004 ford e-150?
If the rear air conditioning is not working, this could be due to one of severalÊproblems. It could be due to a blown fuse.
What is the working principle of pneumatic?
air pressure
Does a landlord have to fix air conditioning in Arizona?
I don't know Arizona laws specifically but ... I expect the law will say if the property had working air conditioning when you signed the lease and moved in, then it is the obligation of the landlord to maintain it in working condition.
How do i troubleshoot the central air conditioning unit?
Determine what is not working properly, then determine why.
What is the function of an air handling unit?
The operating principle of air handling unit is by circulating and then conditioning air flow. This is achieved by cooling, heating and ventilating the units.
What is wrong with your air conditioning on Kia Sedona?
Several things can cause your Kia air conditioning to stop working. The most common cause is a need for the Freon to be recharged.
Explain the working principle of turbo generator?
The working principle of a turbo generator is that of forcing extremely hot condensed air into the piston chamber. The hot condensed air reduces the need for fuel.
What is the working principle of compressor air?
To deliver air at a high pressure than originally taken in.
Can you suffocate in a car if the windows are closed and the air conditioning is not working?
Yes, it is possible to suffocate in a car if the windows are closed and the air conditioning is not working, as the lack of fresh air circulation can lead to a buildup of carbon dioxide and a decrease in oxygen levels inside the car. This can result in suffocation or asphyxiation.
Can you bypass the air conditioning pulley on a 1995 infiniti g20?
The air conditioning pump can be bypassed on a 1995 Infiniti G20 if the pump is not working properly. The vehicle will need a new fan belt that will fit properly. A fan belt for this type of vehicle that does not have air conditioning will be best.
When air con is working start to drive it starts bowing hot air?
There is a refrigerator in there to condense out and collect moisture in the air (that's what air conditioning is). This refigerator takes a little while to cool down when you switch on, so for a period it isn't air-conditioning at all.
