PROBLEM TO BE SOLVED: To provide a heat pump heat source system for calculating supply heat quantity of a heat pump heat source without providing a heating circulation path with a flow rate detector.SOLUTION: A heat medium temperature sensor 63 detects temperature TH2 of a heat medium in a heat pump circulation path 52 between a compressor 54 and a heat pump heat exchanger 55. A heat medium temperature sensor 64 detects temperature TH3 of the heat medium in the heat pump circulation path 52 between the heat pump heat exchanger 55 and an expansion valve 56. A heat pump heat medium temperature sensor 57 detects temperature TH5 of a heat medium in the heat pump heat exchanger 55. Supply heat quantity of a heat pump 51 is calculated from the temperature TH2, TH3, TH5 on the basis of a Mollier chart of the heat medium of the heat pump circulation path. |
