<P>PROBLEM TO BE SOLVED: To provide a heat pump type hot water supply device improving safety of the device by preventing refrigerant pipes of high pressure from being exposed to the outside, and improving energy efficiency of the heat pump type hot water supply device. <P>SOLUTION: The heat pump type hot water supply device is composed of a heat pump unit 11 integrating a refrigerant circuit including a compressor 16, a heat pump heat exchanger 18 and a refrigerant-water heat exchanger 27, and using natural refrigerant, a hot water supply tank 26 for storing hot water heated by the refrigerant-water heat exchanger 27, and a hot water supply unit 12 including a water-water heat exchanger 28 for reheating hot water in a bathtub by heat exchanging between hot water from an upper part in the hot water storage tank 26 and hot water from the bathtub 14. A hot water supply pipe 36 connected from the hot water supply tank 26 to the refrigerant-water heat exchanger 27 in the heat pump unit 11, a bathtub pipe 51 connected from the water-water heat exchanger 28 to the bathtub 14, and a water line pipe 38 connected to the hot water supply tank 26 are extended from the hot water supply unit 12. <P>COPYRIGHT: (C)2011,JPO&INPIT |
