A will after that pump the cooling agent gas up to a high pressure and temperature. Throughout the following phase of the process the gas gets in a type of heat exchanger, usually called the or condenser.


As it cools it will condense right into its liquid state. Some sort of or blood vessel will manage the cooling agent liquid circulation to make certain the appropriate rate. The fluid cooling agent is returned to another warm exchanger where to evaporate, for this reason the heat exchanger on this side of the system is often called the or evaporator.
