Abstract

1. Refrigeration plant with points of use at different evaporation temperatures (-38 degrees C, -10 degrees C, -6 degrees C, -1 degrees C) comprising a plurality of refrigerating centrals or stages each having a plurality of motor-driven compressors and its own points of use at a single evaporation temperature, characterized in that it comprises a motor-driven compressor (20, 44) forming a refrigerating stage of the plant and interconnected with the other refrigerating centrals or stages thereof by means of conduits provided with valves, this motor-driven compressor being usually separated from the refrigerating circuits of these refrigerating stages to provide refrigeration to its own points of use (29, 60) and occasionally separated from its own points of use (29, 60) and connected to one of these refrigerating circuits whereof one of the motor-driven compressors has failed to be used as an auxiliary motor-driven compressor.
