Air Conditioner Evaporator and Condenser:

All air conditioning systems holds at least two heat exchangers, commonly known as the evaporator and the condenser. In case, condenser or evaporator, the refrigerant flows within the heat exchanger and transfers heat, either releasing or gaining it to the cooling medium. Generally, the cooling medium is air or water. In that case of the condenser, the hot, high pressure refrigerant gas has to be condensed to a subcooled liquid.

The condenser accomplishes this through cooling the gas, transferring its heat to either water or air. The cooled gas then condenses within a liquid. In the evaporator, the subcooled refrigerant flows into the heat exchanger, other than the heat flow is reversed, along with the associatively cool refrigerant absorbing heat from the hotter air flowing on the outside of the tubes. That cools the air and boils the refrigerant.
