PERATION
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.
