Patent ID: 7028502

Claim:
A refrigerating apparatus in which expansion mechanisms ( 46 , 52 ) and application-side heat exchangers ( 45 , 51 ) in a first channel and an expansion mechanism ( 42 ) and an application-side heat exchanger ( 41 ) in a second channel are connected in parallel to a compression mechanism ( 2 ) and a heat-source side heat exchanger ( 4 ), the compression mechanism ( 2 ) is configured by a first compressor ( 2 A) and a second compressor ( 2 B) and a plurality of operation modes can be set, wherein the compression mechanism ( 2 ) is configured so as to be capable of being switched between at least two operation patterns, in a predetermined operation mode, among a first pattern of driving the first compressor ( 2 A) and the second compressor ( 2 B), a second pattern of driving only the first compressor ( 2 A) and a third pattern of driving only the second compressor ( 2 B).
