PROBLEM TO BE SOLVED: To heat pump system that can heat an object fluid while continuing the operation of a refrigerant circuit, without suppressing the heating amount of a heat medium by an auxiliary heating part.SOLUTION: A heat pump system 10 includes: a Peltier element 2b that absorbs heat from a heat medium heading from a heating heat exchanger 22 of a heat medium circuit 20 to a radiator 12, and discharges heat to a heat medium heading from the radiator 12 of the heat medium circuit 20 to the heating heat exchanger 22; and a controller 40 that performs a first operation controlling the operation of the Peltier element 2b so that the inlet temperature of a heat medium of the radiator 12 is lower than the outlet temperature of a refrigerant of the radiator 12 and the water temperature of a thermostat bath 23 approaches a target temperature. |
