摘要： In order to create a refrigeration system comprising a refrigerant circuit (10), in which a main mass flow (56) of a refrigerant is guided, which may be adapted to different operating conditions in an optimum manner it is suggested that at least two refrigerant compressors (12a, 12b, 12c), which can be switched on individually for the purpose of compressing the main mass flow, be arranged in the refrigerant circuit, that at least two of the refrigerant compressors each have at least one additional compressor stage (70), that each of the additional compressor stages be able to be used optionally for the compression of refrigerant from the main mass flow or for the compression of refrigerant from the additional mass flow (86) and that a control (90) be provided, with which such a number of additional compressor stages for the compression of refrigerant from the additional mass flow can be switched on in a first operating mode as a function of the operation conditions that the expansion cooling device (24, 28) liquefies the main mass flow and reduces its enthalpy.

摘要： In order to improve a refrigerating plant comprising a refrigerant circuit, which has a main stream of refrigerant flowing through an evaporator, a compressor, a condenser and a collector one after the other, and an oil circuit for the compressor with an oil cooler such that the oil cooler can be operated as simply and reliably as possible, it is suggested that the oil cooler be adapted to be cooled by a branch stream of liquid refrigerant from the refrigerant circuit, that the branch stream circulate in a branch circuit on the pressure side, that the branch circuit branch off from a collector arranged downstream of the condenser in the main stream of the refrigerant circuit, convey liquid refrigerant to the oil cooler and then supply the refrigerant evaporated at least partially in the oil cooler to the main stream of refrigerant on the pressure side upstream of the condenser and that a pumping device driven by the main stream of refrigerant flowing from the compressor to the condenser pump the branch stream of refrigerant through the branch circuit.
