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 (Figure 5, Item 1).
The refrigerant must be converted into a liquid that has high temperature and high pressure. The refrigerant must
be converted into a liquid in order to increase the efficiency of the air conditioning system. The condenser
(Figure 5, Item 1) 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 location 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 (Figure 5, Item 1), the
condenser absorbs heat from the refrigerant vapor. The condenser transfers the heat to the outside air. The
temperature of the refrigerant and the pressure 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, high pressure liquid. When the refrigerant is converted into a liquid, the refrigerant
leaves the condenser (Figure 5, Item 1).
