The invention relates to a vehicle heating and air-conditioning facility, which is used for heating in hot pump operation, is used for cooling in air conditioner operation and is provided with a refrigerant loop. The refrigerant loop comprises at least one electrically operable compressor, an external air heat exchanger, an expansion mechanism, and an internal air heat exchanger. The rotation speed of the compressor can be adjusted by a frequency converter/a converter. The frequency converter/converter is configured that during the operation of the air conditioner, in the course of at least one refrigerant line, more than 70% of the heat dissipation can be cooled via the heat exchange connection by means of a refrigerant flowing from downstream of the internal air heat exchanger to the compressor in the refrigerant circuit as a suction gas flow. During the operation of the heat pump, more than 70% of the heat dissipation of the frequency converter/converter can be cooled by means of air in the course of at least one refrigerant line. The invention relates to a cooling plate for the device, and a method for adjusting the cooling of the frequency converter/the converter.
