Abstract: PURPOSE: To store hot water and control the temperature of the stored hot water at a fixed temperature, by using a compressor whose pole number can be changed depended on the fluctuation in the cooling load and by utilizing the waste heat produced by cooling.  
     CONSTITUTION: The compressor 4 changeable in the number of its poles, a heat source side water heat exchanger 5, a restricting mechanism 6 and a load side air heat exchanger 7 are connected to one another through coolant pipes. The heat source side water heat exchanger 5 is connected through water pipes 13, 14 to a hot  water supply circuit containing a heat accumulation tank (electric water heater) 1, a circulating pump 12 of controllable flow rate and a hot water supply pipe 10. When the compressor 4 and the circulating pump 12 are driven, cooling is performed and hot water can be stored in the tank 1 by the waste heat due to the cooling. When the number of poles of the compressors 4 is changed from 2 to 4 according as the cooling load decreases, the condensation temperature of the heat exchanger 5 varies stepwise. Therefore, if the flow rate of the pump 12 is reduced in response to the variatin in the con densation temperature, the temperature of the hot water can be kept constant.
