Abstract: A refrigeration cycle device has a cooling heat exchanger, an evaporation-pressure control valve, an inside-air ratio adjuster, and a controller. The evaporation-pressure control valve controls an evaporation pressure of a refrigerant in the cooling heat exchanger. The inside-air ratio adjuster changes a ratio of an inside air to an entire volume of the air exchanging heat with the refrigerant in the cooling heat exchanger. The controller controls the inside-air ratio adjuster. The evaporation-pressure control valve increases the evaporation pressure of the refrigerant as a flow rate of the refrigerant flowing through the evaporation-pressure control valve increases. The controller, in a first mode, increases the ratio of the inside air as an evaporation temperature of the refrigerant in the cooling heat exchanger falls.
