Abstract

An air-conditioning system for an electrically driveable motor vehicle includes a coolant-conducting HVA circuit to which a traction battery and an evaporator for cooling the traction battery are connected, a coolant-conducting heating circuit for controlling the temperature of an interior compartment of the motor vehicle, to which heating circuit a condenser for releasing thermal power is connected, a coolant-conducting refrigeration circuit, to which the evaporator, the condenser and a compressor are connected, a heat exchanger, which is connected to the HVA circuit and which is controllably connectable to the heating circuit and which is configured for coolant-based transfer of thermal power from the heating circuit into the HVA circuit, and a control device.
