Claim 2:
3. The refrigeration cycle device according to claim 1, wherein, when the detection signal for outside air temperature is less than or equal to a first temperature, when the detection signal for temperature of the main refrigerant at the main heat-source-side heat exchanger is less than or equal to a second temperature, when the detection signal for subcooling degree of the main refrigerant at the outlet of the subcooling heat exchanger is greater than or equal to a first subcooling degree, or when the detection signal for subcooling degree of the main refrigerant at the outlet of the sub-use-side heat exchanger is greater than or equal to a second subcooling degree, the controller determines that the second switching condition has been satisfied and switches to perform the cooling action of the subcooling heat-exchanger.
