Method for Operating a Refrigerant Circuit as a Heat Pump and Heat Pump Operable as a Refrigerant Circuit

摘要

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.

1. A method of operating a refrigerant circuit as a heat pump, the method comprising the acts of:
compressing a refrigerant, via a compressor, and pumping the compressed refrigerant through a refrigerant/heating heat exchanger; expanding refrigerant coming from an output of the refrigerant/heating heat exchanger in at least a first expansion element; flowing the expanded refrigerant from the first expansion element through at least one evaporator to an input of the compressor; and branching-off the refrigerant at a branch-off point of the refrigerant/heating heat exchanger located between an input of the refrigerant/heating heat exchanger and the output; and conducting the branched-off refrigerant, via a second expansion element, toward the suction input of the compressor.
