PURPOSE:To increase the amount of accumulated heat in a hot water storing tank, by restarting a compressor and a water circulating pump after temporarily suspending them in accordance with a signal from an inlet water temperature detector of a water heater. CONSTITUTION:The compressor 8, a radiator 9a, a decompressor 10 and a heat absorbing apparatus 11 constitute a refrigerating cycle, and a water heater 9b connected to the radiator 9a is in communication with a hot water storing tank 12 with a pump 13 between the water heater 9b and the hot water storing tank 12. When a switch 15 is closed, the operation of the compressor 8 and the pump 13 is started, and when an inlet water temperature detector 14 for detecting the temperature of water to the water heater 9b detects a water temperature equal to a set water temperature or above, a high voltage is energized to the base of a transistor 20 so that a timer circuit 21 is charged to open a switch 16 for a certain period of time, and after the compressor 8 and the pump 13 are stopped, the switch 16 is closed again to start the operation of the compressor 8 and the pump 13. After the operation is carried out for a certain period, the switch 16 is opened. |
