Title:
REFRIGERATING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2010/038360
Kind Code:
A1
Abstract:
In a refrigerating apparatus which performs a refrigerating cycle of two-stage compression, a plurality of compression mechanisms (20, 30) comprise four cylinder chambers (C1, C2, C3, C4) so that the volume ratio of a compressor (1) formed by mechanically connecting the compression mechanisms (20, 30) through one drive shaft (53) can be adjusted.  The refrigerating apparatus comprises selector valves (7a, 7b) for changing the ratio of the suction volume of the low-stage compression mechanism to the suction volume of the high-stage compression mechanism.
