When the refrigerant leaves the compressor, the refrigerant is a vapor. The temperature of the refrigerant is high and the
pressure of the refrigerant is high when the refrigerant leaves the compressor. The increase in pressure of the refrigerant
causes an increase in temperature of the refrigerant. The refrigerant vapor leaves the compressor and the refrigerant
enters the condenser.
The refrigerant must be converted into a liquid that has high temperature and high pressure. The refrigerant must be con-
verted into a liquid in order to increase the efficiency of the AC system. The condenser converts the refrigerant vapor
into a liquid that has high temperature and high pressure.
When the refrigerant vapor leaves the compressor, the refrigerant vapor enters the condenser. The condenser is in a loca-
tion that is exposed to outside air. In order to convert the refrigerant into a liquid, the refrigerant must lose heat. The
refrigerant must reach the temperature of saturation. At the temperature of saturation, the refrigerant vapor will become
a liquid. The temperature of saturation of the refrigerant depends on the pressure of the refrigerant.
As the high temperature, high pressure refrigerant vapor passes through the condenser, the condenser absorbs heat from
the refrigerant vapor. The condenser transfers the heat to the outside air. The temperature of the refrigerant and the pres-
sure of the refrigerant decrease until the temperature of saturation is reached. When the temperature of the refrigerant
vapor is equal to the temperature of saturation, the refrigerant becomes a high temperature and high pressure liquid.
When the refrigerant is converted into a liquid, the refrigerant leaves the condenser.
