PROBLEM TO BE SOLVED: To provide a refrigeration cycle device capable of improving pressure loss by allowing only a liquid refrigerant to flow to a supercooling circuit of a small pipe diameter and allowing a gas refrigerant to flow to a part of a large pipe diameter in heating, improving the heating performance and reducing the frost formation on an outdoor heat exchanger. SOLUTION: In this refrigeration cycle device constituted by connecting an outdoor machine 1 composed of a compressor 3, a four-way valve 4 and the outdoor heat exchanger 10, and an indoor machine 2 composed of an indoor flow rate control valve 7 and an indoor heat exchanger 6, by means of a gas-side extension pipe 5 and a liquid-side extension pipe 8, and comprising a supercooling circuit 12 between the outdoor heat exchanger 10 and the indoor flow rate control valve 7, a gas-liquid separator 9 connected with a liquid pipe 14 for allowing only the liquid refrigerant after gas-liquid separation to flow to the supercooling circuit of small pipe diameter, and a gas pipe 13 for allowing only the gas refrigerant after gas-liquid separation to flow to the part of large pipe diameter in heating, is mounted just before the supercooling circuit 12.
