Working Principle of Air Conditioner

When the liquid refrigerant turns into gas in the evaporator coil, the heat from the room air is absorbed by the refrigerant and cools the air as it passes through the coil. Fans in indoor units send cooled air back through the ducts of your home to the various living areas.  R22, with the molecular formula CHCLF2, is the most commonly used refrigerant in air conditioning systems. Different temperatures constantly change their state (solid, liquid, gas).
