Abstract: An air conditioner includes a heat medium circuit, a refrigerant cycle device, a discharge capacity controlling section, a heat generation amount controlling section, a target temperature determining section, and an upper limit determining section. The heat medium circuit includes a heating heat exchanger and an electric heater. The refrigerant cycle device exchanges heat between a heat medium in the heat medium circuit and a refrigerant discharged from an electric compressor. During a heater priority mode, the rotational speed of the compressor is increased to reach an upper limit and a heating amount of the heater is increased as a temperature difference increases. During a compressor priority mode, the heating amount of the heater is decreased and the rotational speed is increased to compensate for a decreasing amount.
