Claim Text:
1. A refrigeration circuit for circulating a refrigerant and comprising in the direction of flow of the refrigerant: a compressor; at least one condenser for rejecting heat to ambient air; an expansion device; and an evaporator; the refrigeration circuit further comprising a collecting container, the output of which being connected to the expansion device; a heat rejecting heat exchanger for heat exchange of the refrigerant to a heat pump system, the output of the heat rejecting heat exchanger being connected to the collecting container and at least one valve connecting the heat rejecting heat exchanger or the at least one condenser to the output of the compressor depending on the availability of cooling power at the heat rejecting heat exchanger; and a gas-liquid-separator arranged in a line connecting an output of the heat rejecting heat exchanger to the collecting container, the gas-liquid-separator separating the refrigerant coming from the heat rejecting heat exchanger into a gaseous phase refrigerant portion and liquid phase refrigerant portion and having a gaseous phase output and a liquid phase output.
