<P>PROBLEM TO BE SOLVED: To provide a heat pump water heater capable of efficiently heating water by thermally insulating peripheral spaces of a compressor and a refrigerant pipe without increasing manufacturing cost and the size of the heater. <P>SOLUTION: The heat pump water heater includes: a compressor housing unit 111 which is formed of a partition plate 27 and a housing external plate 32 forming an air blow circuit for blowing air to an evaporator 24 and in which a compressor 21 is disposed; an electrical component housing unit 28 which is disposed above the compressor housing unit 111; a refrigerating cycle component insulating part 113 in which insulator contacting the partition plate 27 and an inner side of housing external plate 32 surrounds at least the compressor 21 except the electrical component housing unit 28.The insulating component constituting the refrigerating cycle component insulating part 113 is disposed so as not to cover a connecting pipe portion 112 of the compressor 21 and the evaporator 24. Accordingly, whole space inside the refrigerating cycle component insulating part 113 can be insulated except the connecting pipe portion 112 with a complex configuration and thereby efficiency can be improved by insulation without increasing the cost. <P>COPYRIGHT: (C)2013,JPO&INPIT |
