A/C System Basic Climate Control
•
In the A/C system the refrigerant is found in two different states, and two different
temperatures. As the refrigerant leaves the compressor it is a warm and high-pressure
gas. It then travels through the condenser where the outside air coming in contact with
the fins of the condenser absorbs the heat from the refrigerant, cooling it and liquifying it.
The liquid then travels to the expansion valve, or the fixed orifice where it is reduced in
pressure.
