Abstract
A refrigeration circuit is disclosed circulating a refrigerant and comprising in the direction of flow of the refrigerant a compressor (2); at least one condenser (14, 16) for rejecting heat to ambient air; an expansion device (8); and an evaporator (10). The refrigeration circuit further comprises a collecting container (12), the output of which being connected to the expansion device (8); a heat rejecting heat exchanger (4) for heat exchange of the refrigerant to a heat pump system, the output of the heat rejecting heat exchanger (4) being connected to the collecting container (12); and means (V1, V2) for connecting the heat rejecting heat exchanger (4) or at least one of the condenser(s) (14, 16) to the output of the compressor (2) depending on the availability of cooling power at the heat rejecting heat exchanger (4).
