PROBLEM TO BE SOLVED: To boil up high temperature hot water while enhancing the reliability of apparatus by collecting solar heat and atmospheric heat. SOLUTION: The heat pump type solar hot water supply system comprises a coolant circuit including a compressor 1, a condenser 2, a pressure reducing means 3 and an evaporator 4, a hot water supply circuit 9 including a hot water supply heat exchanger 6 exchanging heat with the condenser 2 and a hot water storage tank 7, and a solar heat collecting circuit 15 coupled with a solar heat radiator 10 exchanging heat with the evaporator 4 and a solar heat collecting plate 11. Coolant flowing through the evaporator 4 is evaporated and gasified by a medium collected solar heat through the solar heat collecting plate 11 and then compressed by the compressor 1 to produce high temperature high pressure gas. Water in the hot water supply heat exchanger 6 coupled with the hot water storage tank 7 is then heated by condensation heat through the condenser 2. |
