Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/143343
Kind Code:
A1
Abstract:
Disclosed is a refrigeration cycle device (100A) comprised of a first compressor (1) containing a first compression mechanism (11), an expansion mechanism (13), and a first motor (12); a second compressor (2) containing a second compression mechanism (21) and a second motor (22); and a control device (6). The control device (6) reduces the number of rotations of the second motor (22) by a reduction speed higher than the reduction speed at which the number of rotations of the first motor (12) is reduced, in a stop operation wherein the number of rotations of the first motor (12) and the second motor (22) is reduced to stop the first motor (12) and the second motor (22).
