notes
The compressor draws in the superheated refrigerant vapor (B) and
compresses it to a pressure and temperature (C) high enough that it can reject
heat to another fluid. This hot, high-pressure refrigerant vapor then travels to
the condenser.
Within the condenser, heat is transferred from the hot refrigerant vapor to
relatively cool ambient air or cooling water. This reduction in the heat content
of the refrigerant vapor causes it to desuperheat, condense into liquid, and
further subcool before leaving the condenser (D) for the expansion device.
