Most of us have air conditioners either at the work place or at home. We enjoy sitting in a fully air conditioned room, but do you know how it works? Are you fully aware about the cooling mechanism of an air conditioner?

•    The process of cooling done by a refrigerator and an air conditioner is almost the same, both use Freon to cool the air. This Freon is mixed with a small amount of oil to lubricate the compressor.
•    To turn the cool Freon air to hot gas, the compressor compresses it then the hot gas passes through a coil system and lets the heat to cool down.
•    Later, the cooled air gets converted into liquid as it gives out heat through the coils. This liquid begins to evaporate so as to become a cool, low pressure Freon gas.
•    The cold Freon gas passes through the coil and the cold is released into the air so that the air gets cooled while the heat is absorbed and removed through the coils as hot gas.
•    This procedure is repeated so as to circulate cool air.
