REFRIGERATION DEVICE

Document Type and Number:

WIPO Patent Application WO/2015/115546

Kind Code:

A1

Abstract:

Provided is a heat source unit capable of exhibiting adequate performance by stably adjusting the degree of opening of electrically operated valves provided in correspondence with each of multiple heat exchangers which are connected to each other in parallel. A first heat exchanger (24) and a second heat exchanger (25) are connected to each other in parallel, and are provided respectively with a first heat-source-side flow volume adjustment valve (26) and a second heat-source-side flow volume adjustment valve (27), which adjust the flow volume on the upstream side when the heat exchanger functions as an evaporator. A heat-source side control unit (20) identifies the total degree of opening of the first heat-source-side flow volume adjustment valve (26) and the second heat-source-side flow volume adjustment valve (27) on the basis of the temperature of a refrigerant discharged from a compressor (21), and adjusts the relationship between the degree of opening of the first heat-source-side flow volume adjustment valve (26) and the second heat-source-side flow volume adjustment valve (27) on the basis of the temperature of the refrigerant flowing from the first heat-source-side flow volume adjustment valve (26) to the first heat exchanger (24) and the temperature of the refrigerant flowing from the second heat-source-side flow volume adjustment valve (27) to the second heat exchanger (25).
