Abstract

PURPOSE: To provide a refrigerating plant, in which unbalance will never be generated in the amount of refrigerant in compressors arranged in parallel.
CONSTITUTION: A plurality of compressors 111, 112 are provided with oil separaters 121, 122 respectively and returning pipes 211, 212, returning separated oil to respective compressors 111, 112 through suction pipes 231, 232, are connected to the oil separaters 121, 122 while at least one set of the compressors is stopped when refrigerating load is reduced. The returning pipes 211, 212 are connected mutually through a connecting pipe 24 while the connecting pipe 24 is provided with control valves 25, 271, 272 for introducing refrigerant from the suction pipe 231 of the stopped compressor 111 into the suction pipe 232 of the compressor 112 under operation.
