Abstract

A refrigeration plant comprising a refrigerant circuit (10) including a first pump (12), a first heat consumer (11, 14), at least two secondary heat exchangers (31-33) which are connected in parallel across conducting parts (10a, 10b) of the circuit (10) said parts (10a, 10b) being connecting to the heat consumer (11) and functioning to cool a respective heat emitting unit (51-53, 51'-53') which is through-passed by refrigerant and which belongs to at least one refrigeration plant (41';41-43), such as a refrigerator or freezer. The pumps (12 21) are adapted to drive the refrigerant in mutually opposite directions such that the circuit will obtain a low pressure side (10a) and a high pressure side (10b). The plant also includes a pressure difference sensor (22) which detects the pressure difference between the low pressure side (10a) and the high pressure side (10b). The second pump (21) is adapted to deliver a generally constant flow of refrigerant. A shunt line (60) is established between the high pressure side (10b) and the low pressure side (10a) and contains a device (61) for controlling the flow of refrigerant through the shunt line (60), wherein the flow controlling device (61) is controlled by the pressure difference sensor so as to maintain a generally constant pressure difference between the high pressure side (10b) and the low pressure side (10a).
