Abstract
A method of operating a refrigerant circuit as a heat pump is provided. By way of a compressor, refrigerant is compressed and is pumped through a refrigerant/heating heat exchanger. The refrigerant coming from the refrigerant/heating heat exchanger is expanded in at least a first expansion element. The refrigerant expanded by way of the first expansion element flows to a suction input of the compressor through at least one evaporator. At a branch-off point of the refrigerant/heating heat exchanger situated between a refrigerant input and a refrigerant output of the refrigerant/heating heat exchanger, refrigerant is branched off and is guided by way of a second expansion element in the direction of the suction input of the refrigerant compressor.
