PURPOSE:To permit to utilize effectively the calorific value of heat source water supplied to the absorption heat pump by a method wherein the supplying amount of hot-water supplied to the absorption heat pump is controlled based on the detecting signal of a temperature sensor, detecting the temperature of hot-water supplied from the absorption heat pump to a hot-water supplying tank. CONSTITUTION:When the temperature of hot-water, supplied from the outlet pipe 32 of heat pump to the hot-water supplying tank 10, is lower than a set hot-water supplying temperature, a control unit operates a circulating pump 46 in a condition that the pump is operated with large number of poles to reduce the amount of hot-water, supplied from the hot-water supplying tank 10 to the absorption heat pump 26, than a rated flow amount. The temperature of hot-water supplied to the hot-water supplying tank 10 is increased suddenly and it arrives at a set hot-water supplying temperature range. When the temperature has arrived at said range, the operation of the circulating pump 46 is switched to the operation with small number of poles and the hot-water of the rated flow amount is supplied to the heat pump 26. When the temperature has become higher than the set range, the control unit reduces the number of poles of the circulating pump 46 to increase the circulating amount of hot-water than the rated flow amount and control the temperature of hot-water supplied to the upper part of the tank 10 to a temperature within the set hot-water supplying temperature range. |
