METHOD FOR OPERATING A REFRIGERANT CIRCUIT OF A MOTOR VEHICLE, AND MOTOR VEHICLE

A method for operating a refrigerant circuit of a motor vehicle, with a compressor which, in a heating mode of the refrigerant circuit, conveys a refrigerant through a first condenser, by which an air flow is heated. The compressor conveys the refrigerant through a second condenser for further cooling. At least a partial flow of the refrigerant coming from the second condenser is expanded by a first expansion member and supplied to a first evaporator, by which a humidity of the air flow can be reduced. To increase the heating power available at the first condenser, a further partial flow of the refrigerant is expanded by a second expansion member and supplied to a second evaporator. The refrigerant coming from the evaporators is supplied to a suction side of the compressor.
