<P>PROBLEM TO BE SOLVED: To attain reduction in cost and compact a heat pump unit. <P>SOLUTION: The water heater comprising a heat pump circuit 19 formed by a compressor 13, a refrigerant-water heat exchanger 14, an air heat exchanger 17 constituting an evaporator, and a blowing fan; an inflow pipe for supplying water to the refrigerant-water heat exchanger 14; and an outflow pipe supplying water heated by the refrigerant-water heat exchanger as hot water is provided with a heat absorption means 18 for guiding a refrigerant pipe between the evaporator 17 and the compressor 13 to a position adjacent to the refrigerant-water heat exchanger 14 in no contact and absorbing radiant heat generated from the refrigerant-water heat exchanger 14. According to this, the cost can be effectively reduced without degradation of energy efficiency, and the heat pump unit can be miniaturized without specially needing a setting space therefor. <P>COPYRIGHT: (C)2007,JPO&INPIT |
