Title:
REFRIGERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/025614
Kind Code:
A1
Abstract:
A refrigeration device (10) wherein a usage-side unit (12) is connected to a heat-source-side unit (11) via a pair of connecting pipes (14, 15). When the usage-side unit (12) switches from a cooling state to a resting state a controller (90) stops compressors (31a - 31c) and closes a usage-side electromagnetic valve (62) after a heat-source side expansion valve (38) is closed. Consequently, a liquid hammer phenomenon caused by opening the usage-side electromagnetic valve (62) of the usage-side unit (12) is suppressed.
