WIPO Patent Application WO/2003/062718

Kind Code:

A1

Abstract:

A refrigerating device comprising three compressors (2A, 2B, 2C) and two systems of utilization-side heat exchangers (41), (45, 51) is arranged so that the first compressor (2A) is used exclusively for the utilization-side heat exchangers (45, 51) of the first-system-side circuit while the third compressor (2C) is used exclusively for the utilization-side heat exchanger (41) of the second-system-side circuit and so that second compressor (2B) is used by switching between the utilization-side heat exchangers (45, 51) of the first-system-side circuit and the utilization-side heat exchanger (41) of the second-system-side circuit, whereby the arrangement of the suction-side piping is simplified and so is the operation control.
