ABSTRACT:
In a heat pump system for domestic hot water, a compressor section 18 provides working fluid at a multiplicity of pressures. Multiple condensers 12, 14 are arranged so that higher pressure working fluid is in heat exchange relationship with higher temperature water. Upon leaving the condensers 12, 14, working fluid is independently expanded and then combined, and it runs through a single evaporator 31 before returning to the compressor 18. The water may be circulated past an external condenser 12, 14 or the condensers 46, 48 may be immersed in a hot water storage tank 38.
