Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a refrigeration cycle device capable of reducing pressure loss caused in a gas connection pipe and eliminating insufficiency of capacity even if using refrigerant having large specific volume. SOLUTION: This refrigeration cycle device is constituted by connecting a compressor 100, a heat source side heat exchanger 130, a pressure reducing device, and a use side heat exchanger 220 with the refrigeration cycle device sequentially with pipes and switching between cooling operation and heating operation by a selector valve. This refrigeration cycle device is provided with a refrigerator using the refrigerant having specific volume being 1.5 times vapor specific volume or more at the same evaporating temperature for R410A as operation refrigerant and undercooling the refrigerant coming out of the heat source side heat exchanger when performing cooling operation.
