    摘要： The invention relates to a vapour compression refrigeration system (1), comprising a main refrigerant circuit (2) which in turn comprises: - a main gas cooler or condenser (10) arranged in a high pressure branch (BHP); - at least a first main evaporator (20') arranged in a first low pressure branch (BLP1); - at least one main compressor (30') which fluidically connects the first low pressure branch (BLP1) to the high pressure branch; - an expansion device (40) connecting the high pressure branch (BHP) to the intermediate pressure branch (BMP) downstream of said gas cooler or condenser (10). The system (1) comprises a by-pass branch (BB) connecting the high-pressure branch (BHP) to the intermediate pressure branch (BMP) and provided with a by-pass valve (60). The system comprises an auxiliary/secondary vapour compression refrigerant circuit (100) in turn comprising: - a secondary gas cooler or condenser (111) arranged in a secondary high pressure branch (BHPs); - at least one secondary evaporator (112) arranged in a secondary low pressure branch (BLPs); - a secondary expansion device (113) connecting the secondary high pressure branch (HPs) to the secondary low pressure branch (BLPs). The system comprises a rotary pressure exchanger (50) fluidically connected to the by-pass branch downstream of the by-pass valve (60) and the secondary refrigerant circuit (100).
