Document Type and Number:
WIPO Patent Application WO/2007/102496
Kind Code:
A1
Abstract:
A compressor (20) includes compressing mechanisms (61, 62) having four compression
chambers (61, 62, 63, 64). In the compressor (20), the first compression chamber
(61) and the second compression chamber (62) have volume fluctuation cycle phases
different by 180 degrees and the third compression chamber (63) and the fourth
compression chamber (64) have volume fluctuation cycle phases different by
180 degrees. An air cylinder halt operation compresses a coolant by a single
stage in the first compression chamber (61) and the second compression chamber
(62) and stops the compression operation in the third compression chamber (63)
and the fourth compression chamber (64). In a two-stage compression operation,
the coolant compressed by a single stage in the first chamber (61) and the second
chamber (62) is further compressed in the third compression chamber (63) and
the fourth compression chamber (64).
