Title:
Refrigerating device
Document Type and Number:
Japanese Patent JP5949831
Kind Code:
B2
Abstract:
A first heat-source-side flow rate adjusting valve (26), an opening degree of which is adjustable, is connected to a liquid side of an upper-side first heat-source-side heat exchanger (24), and a second heat-source-side flow rate adjusting valve (27), an opening degree of which is adjustable, is connected to a liquid side of a lower-side second heat-source-side heat exchanger (25). In a defrost operation for defrosting the first and second heat-source-side heat exchangers (24, 25), the opening degrees of the first and second heat-source-side flow rate adjusting valves (26, 27) are controlled so as to achieve a defrost flow rate ratio, which is a flow rate ratio at which more refrigerant flows to the second heat-source-side heat exchanger (25) than during an air-cooling operation.
