    • PROBLEM TO BE SOLVED: To obtain a high temperature water medium in a heat pump system capable of heating the water medium by using a heat pump cycle. SOLUTION: The heat pump system 1 includes a heat source side coolant circuit 20 having a heat source side compressor 21, a first utilization side heat exchanger 41a functioning as a radiator for a heat source side coolant, and a heat source side heat exchanger 24 functioning as a radiator for the heat source side coolant. Furthermore, it includes a utilization side coolant circuit 40a having a utilization side compressor 62a, a coolant-water heat exchanger 65a functioning as a radiator for a utilization side coolant to heat the water medium, and the first utilization side heat exchanger 41a functioning as an evaporator for the utilization side coolant by heat radiation of the heat source side coolant. In such a case, capacity control of the heat source side compressor 21 is carried out such that a saturation temperature equivalent to a pressure of the heat source side coolant in discharge of the heat source side compressor 21 becomes a target temperature, and capacity control of the utilization side compressor 62a is carried out such that a saturation temperature equivalent to a pressure of the utilization side coolant in discharge of the utilization side compressor 62a becomes a target temperature.
