Claim 10:
11. The refrigeration cycle device according to claim 2, wherein, when the outside air temperature is less than or equal to a third temperature, when the temperature of the main refrigerant at the main heat-source-side heat exchanger is less than or equal to a fourth temperature, when the subcooling degree of the main refrigerant at the outlet of the subcooling heat exchanger is greater than or equal to a third subcooling degree, or when the subcooling degree of the main refrigerant at the outlet of the sub-use-side heat exchanger is greater than or equal to a fourth subcooling degree, the controller determines that the second switching condition is satisfied and switches to perform the cooling action of the subcooling heat-exchanger.
