Abstract

An air conditioning system of a motor vehicle with a refrigerant circuit for operation in a refrigerator mode and a heat pump mode. The refrigerant circuit includes a primary circuit with a compressor, a heat exchanger for heat transfer between the refrigerant and the surroundings, an expansion element and a heat exchanger for heat transfer from the intake air being conditioned for the passenger compartment to the refrigerant, and a first flow path. The flow path extends from a branching point between the compressor and the heat exchanger to an opening and includes a heat exchanger for heat transfer from the refrigerant to the intake air being conditioned for the passenger compartment. The heat exchanger is situated in a flow direction of intake air of the passenger compartment after the heat exchanger.
