The Principle of Air conditioning is to absorbenergy in one place and release it in another place.
The process requires an indoor unit, an outdoor unit and copper piping to connect both. Through the piping the refrigerant gases flow from the indoor unit to the outdoor unit. The refrigerant gas absorbs the energy in one unit and releases it in the other.
A simple explanation of the Air Conditioning Process:
In the Indoor unit a fan blows the warm air over a heat exchanging coil where the cold refrigerant gas flows. The cold refrigerant absorbs the heat from the warm air and cool air is blown into the room. The refrigerant gas circulates through the indoor unit; copper piping then takes the heat from the indoor unit to the outdoor unit. Through compression, the refrigerant gas is heated and its boiling point increases. In the outdoor unit the heat created through compression is released to the outdoor air by means of a fan which blows the outdoor air over a heat exchanging coil. The liquid refrigerant flows back to the indoor unit where the refrigerant is decompressed which enables it to extract heat form the indoor air.
