refrigerant condenses into a liquid state in the condenser
as it loses heat energy.
The pressure of the refrigerant remains high as the liquid
refrigerant is transferred to the expansion valve (6). The
pressure of the refrigerant decreases in the expansion
valve, and the temperature drops to approximately -10°C.

The expansion valve injects the correct amount of
refrigerant into the evaporator, where the heat energy
transferred from the brine causes the refrigerant to
evaporate.
