How Air Conditioners Work
by Guest Post on Oct 23, 2010
An air conditioner works in the same way as a refrigerator. The portable evaporative air conditioners that we see in homes make use of water to cool the air. They are not good in an area with high humidity as the air they blow out is very humid. That is, a special refrigerant gas such as Freon is heated and then cooled through coils to give the cold air. With a fridge, the cold air is contained in an insulated box; air conditioners blow the cool air out into your room.
A compressor is used to compress the gas, making it become hot and high-pressured. As it runs through coils, the heat dissipates and the gas turns to liquid. The next step involves the liquid Freon running through an expansion valve so that it turns back into a cold gas. The Freon is mixed with a little oil that helps to lubricate the inside of the air-conditioner.
Many air-conditioners also use cooling towers to help save on the cost of air-conditioning. These cooling towers are generally found on the roof or at the back of buildings. Basically, they are of mesh with water running through it to help cool off the gas.
