HEAT PUMP SYSTEM

Japanese Patent JP3968653

B2

PROBLEM TO BE SOLVED: To provide a heat pump system of high efficiency, keeping the temperature of the water low, which is flowing into a refrigerant-water heat exchanger by a means of simple constitution.
SOLUTION: This heat pump system comprises a heating circulating circuit 62 to which a hot water storage tank 60 and a heat pump 50 for heating the water in the hot water storage tank 60 are connected, a radiated heat circulating circuit 63 where a radiated heat circulating circuit taking-out port 64 at an upper part of the hot water storage tank 60, a radiated heat heat exchanger 67 connected to a load terminal 72, a heat radiating pump 65, a flow rate adjusting valve 66 and a returning part 68 at a predetermined position of the hot water storage tank 60 are successively connected by a pipe 69, a temperature detecting means for detecting the water temperature in the pipe 69 in adjacent to the returning part 68 of the hot water storage tank 60 of the radiated heat circulating circuit 63 and the water temperature at the predetermined position in the hot water storage tank 60, and a control means 101 for controlling the flow rate adjusting valve 66 to adjust the water temperature detected by the temperature detecting means to the predetermined temperature.
