Title:
FREEZING UNIT
Document Type and Number:
WIPO Patent Application WO/2015/115542
Kind Code:
A1
Abstract:
Provided is a freezing unit capable of minimizing bias of surplus refrigerant in high-pressure receivers, even when a plurality of heat-generating units having high-pressure receivers are connected. A first heat source unit (2a) and a second heat source unit (2b) have compressors (21a, 21b), heat-source-side heat exchangers (24a, 25a, 24b, 25b), receivers (80a, 80b), receiver liquid surface detection tubes (43a, 43b) for detecting approaching fullness, receiver gas release tubes (41a, 41b), and motorized valves (42a, 42b) disposed in the receiver gas release tubes (41a, 41b), respectively. Heat-source-side control units (20a, 20b) control the degree of opening so that the degree of opening of one motorized valve is greater than the degree of opening of the other motorized valve corresponding to the receiver (80a, 80b) that has been detected to be approaching full to control surplus refrigerant distribution.
