Abstract (en)

[origin: EP2336675A1] In order to adjust a volume ratio of a compressor (1) in which a plurality of compression mechanisms (20, 30) are mechanically connected together through a single drive shaft (53), in a refrigerating apparatus in which a two-stage compression refrigeration cycle is performed, the compression mechanisms (20, 30) include four cylinder chambers (C1, C2, C3, C4), and switching valves (7a, 7b) are provided, which are configured to change a ratio of a suction volume of the low-pressure compression mechanism to a suction volume of the high-pressure compression mechanism.
