Title:
REFRIGERATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2016/174874
Kind Code:
A1
Abstract:
In this refrigeration apparatus (10), a plurality of use-side units (12) is connected to a heat-source-side unit (11) through a pair of connecting pipes (14, 15). When one of the use-side units (12) is in a resting state, a controller (90) performs a pressure control operation. The pressure control operation is an operation for controlling the opening of the heat-source-side expansion valve (38) so that the refrigerant pressure of the liquid-side connecting pipe (14) does not exceed a predetermined upper limit. The pressure control operation of the controller (90) suppresses a liquid hammer phenomenon caused by opening the solenoid valve of the use-side unit (12).
