Title:
REFRIGERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/182585
Kind Code:
A1
Abstract:
To the liquid side of a top-side first heat-source-side heat exchanger (24) is connected a first heat-source-side flow adjustment valve (26) having an adjustable aperture, and to the liquid side of a bottom-side second heat-source-side heat exchanger (25) is connected a second heat-source-side flow adjustment valve (27) having an adjustable aperture. Here, during defrost operation for defrosting the first and second heat-source-side heat exchangers (24, 25), the apertures of the first and second heat-source-side flow adjustment valves (26, 27) are controlled to achieve a defrost flow ratio at which more refrigerant flows to the second heat-source-side heat exchanger (25) than during refrigeration operation.
