PROBLEM TO BE SOLVED: To provide a refrigerating cycle device which can be operated efficiently, fixing eyes upon the problem of a conventional refrigerating cycle device such as that it can not be operated in the most efficient condition if it controls the pressure on high pressure side, with the pressure on high pressure side being selected based on either the temperature on outlet side of a radiator or the temperature on inlet side of a pressure reducer as the target value, in a refrigerating cycle device which is charged with a refrigerant capable of getting in supercritical condition in a radiator and has an auxiliary heat exchanger. SOLUTION: This is a refrigerating cycle device which is equipped with a high-pressure-side pressure detector, a radiator-outlet-side temperature detector, and a pressure-reducer-inlet-side temperature detector, and this is equipped with a controller which controls the pressure on high pressure side so that it may be the target value of the pressure on high pressure side being selected based on both the temperature on outlet side of the radiator and the temperature on inlet side of the pressure reducer.
