Document Type and Number:
Japanese Patent JP2008267694
Kind Code:
A
Abstract:
To solve the problem wherein, in the case of a heating and cooling refrigerating cycle, a means for switching the flow of a refrigerant such as a four-way valve is required on upstream of an expander, and in the case of structure indicated in patent document 1, the cost becomes high.
In this refrigerating cycle device, efficiency of the entire refrigerating cycle device can be enhanced by appropriately controlling valve opening of a first flow rate control valve 109 and a second flow rate control valve 113, switching of the four-way valve 104, and ON/OFF of a first compressor 101 and a second compressor 107.
