2. Functionings & principles

A low-pressure liquid refrigerant is vaporized in the heat pump's evaporator and passed into the

compressor. As the pressure of the refrigerant increases, so does its temperature. The heated

refrigerant runs through a condenser coil within the storage tank, transferring heat to the water

stored there. As the refrigerant delivers its heat to the water, it cools and condenses, and then

passes through an expansion valve where the pressure is reduced and the cycle starts over.
