A refrigeration circuit comprises in the direction of flow of a refrigerant at least one compressor; at least one heat rejecting heat exchanger; at least one expansion device; and at least one evaporator. The refrigeration circuit further comprises at least one heat recovery heat exchanger having a refrigeration circuit side and heat recovery system side and being configured for transferring heat between the refrigeration circuit side and the heat recovery system side, wherein the refrigeration circuit side is fluidly connected in parallel to the at least one heat rejecting heat exchanger; and at least one regulation valve, configured for regulating the flow of refrigerant flowing through the refrigeration circuit side of the at least one heat recovery heat exchanger. The at least one regulation valve is switchable between an open position, a closed position, and at least one intermediate position.

Refrigeration system and refrigeration method providing heat recovery

A refrigeration circuit is disclosed 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 comprises 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 means (V, V) for connecting the heat rejecting heat exchanger () or at least one of the condenser(s) () to the output of the compressor () depending on the availability of cooling power at the heat rejecting heat exchanger ().
