Claim:
1. A refrigeration cycle device comprising: a compressor compressing and discharging a refrigerant; a heating heat exchanger that exchanges heat between a high-pressure refrigerant discharged from the compressor and a fluid to be heat-exchanged, to heat the fluid to be heat-exchanged; a first decompression device and a second decompression device that decompress a refrigerant on a downstream side of the heating heat exchanger; a cooling heat exchanger that exchanges heat between the refrigerant flowing out of the second decompression device and the fluid to be heat-exchanged, to cool the fluid to be heat-exchanged, while allowing the refrigerant to flow into a suction side of the compressor; a gas-liquid separator disposed in an external space exposed to an outside air, and separating the refrigerant into gas and liquid phases; an exterior heat exchanger exchanging heat between the refrigerant on the downstream side of the heating heat exchanger and the outside air; and a refrigerant circuit switch switching between refrigerant circuits for circulation of the refrigerant through a cycle, wherein in a cooling mode of cooling the fluid to be heat-exchanged, in a heating mode of heating the fluid to be heat-exchanged,
