Abstract
A heat pump system includes a heat pump cycle, a heating unit, a low-temperature side heat medium circuit, and a control unit. The heat pump cycle includes a compressor, a condenser, and an evaporator. The heating unit heats ventilation air with heat released form refrigerant in the condenser. The low-temperature side heat medium circuit circulates a low-temperature side heat medium such that the refrigerant in the evaporator absorbs heat of the low-temperature side heat medium, and includes a heat source device and a heat amount adjustment unit. The control unit causes an amount of heat transfer in the heating unit for heating the ventilation air to approach a predetermined target value via adjustment in temperature of the low-temperature side heat medium by controlling a rotation speed of the compressor and an operation of at least one of the heat source device and the heat amount adjustment unit.
