Air conditioners give you the much needed thermal comfort during scorching summer. More specifically, air conditioners help to maintain the room temperature at optimum level. They also help in removing airborne particles and humidity from the room. Let’s find out how how these devices work.

Every air conditioner has a compressor inside it. It works to compress and pump the refrigerant gas. Compression of refrigerant produces heat. To dissipate this heat, compressed refrigerant is pumped to the condenser coils where a fan blows the heat out to outer atmosphere.
During the process, refrigerant takes the liquid form. This liquid refrigerant is pumped towards expansion valve. Expansion valve has a temperature sensor connected to it which works in correlation with thermostat settings. Expansion valve releases the appropriate amount of refrigerant to evaporator (cooling coils) where liquefied refrigerant takes gaseous form.
Conversion from liquid to gaseous state due to expansion produces chillness because energy is absorbed from the surrounding. Air when passes through fins (attached to coils) gets cooled and blown to the room. The refrigerant in cooling coils then enters the compressor and gets compressed once again. The cycle continues unless the compressor is shut down./via: quora/Anonymous
