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.
