FREEZING DEVICE
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).
