How an Air Conditioner works:

An air conditioner is basically a ‘refrigerator’ without the ‘insulated box’. It employs the evaporation of a refrigerant, such as Freon, to ensure cooling. The mechanics of the Freon evaporation cycle are largely the same in an air conditioner as in a refrigerator.

This is how the evaporation cycle in an air conditioner usually works:

1. The compressor causes the cool Freon gas to compress, converting it into a hot, high-pressure Freon gas.

2. This hot Freon gas then runs through a set of coils so that it can dissipate its heat. It condenses into a liquid.

3. The air blown across this hot coil gets discharged outside into the open air.

4. The Freon liquid goes through an expansion valve. In the process, the Freon liquid evaporates to then be converted into cold, low-pressure Freon gas.

5. This cold Freon gas runs through a set of coils, which let the gas absorb heat by the passage of room air across the coil.

6. A small amount of light-weight oil is mixed in with the Freon. This lubricates the compressor.
