<P>PROBLEM TO BE SOLVED: To provide a heat pump hot water system of high heat exchange efficiency. <P>SOLUTION: This heat pump hot water system has an outdoor unit 1, a heating/cooling panel 4, an indoor unit 2 having a refrigerant water heat exchanger 21, a hot water storage tank 32, a refrigerant water heat exchanger 31 for the tank, and a water pump 22, and the refrigerant water heat exchanger 31 for the tank is disposed in parallel with the refrigerant water heat exchanger 21. Further this heat pump hot water system includes an indoor-side refrigerant temperature detecting means 24 for detecting a temperature of the refrigerant from the refrigerant water heat exchanger 21, a tank side refrigerant temperature detecting means 26 for detecting a temperature of the refrigerant from the refrigerant water heat exchanger 31 for the tank, a water discharge temperature detecting means 23 for detecting a temperature of the water discharged from the refrigerant water heat exchanger 21, and a tank water temperature detecting means 33 for detecting a temperature in the hot water storage tank 32, and a rising speed in restarting a compressor is slower than a rising speed in starting at a normal time. <P>COPYRIGHT: (C)2010,JPO&INPIT |
