To properly heat air which is blown into a cabin, in a refrigeration cycle device for heating the air blown into the cabin by a thermal medium heated by a refrigerant, and radiating the heat of the thermal medium heated by the refrigerant to an atmosphere.SOLUTION: A refrigeration cycle device comprises: high-temperature thermal medium adjusting parts 25, 26 and 28 for adjusting a high-temperature thermal medium flow rate ratio being a flow rate ratio between a high-temperature thermal medium flowing in an air heater 22, and a high-temperature thermal medium flowing in a heat radiator 23; and a control part 60 for controlling the high-temperature thermal medium adjusting parts 25, 26 and 28 so as to reach a high-temperature thermal medium flow rate ratio at which surplus heat out of heat radiated from a refrigerant to the high-temperature thermal medium by a high-pressure side heat exchanger 12 is radiated to air at the outside of a cabin by the heater 23 with respect to heat necessary for heating air blown into the cabin to a target blowout temperature TAO by the air heater 22.SELECTED DRAWING: Figure 1

    【課題】冷媒で加熱された熱媒体で車室内へ送風される空気を加熱すると同時に冷媒で加熱された熱媒体を外気に放熱させる冷凍サイクル装置において、車室内へ送風される空気を適切に加熱できるようにする。【解決手段】空気加熱器22を流れる高温熱媒体と放熱器23を流れる高温熱媒体との流量比である高温熱媒体流量比を調整する高温熱媒体調整部25、26、28と、高圧側熱交換器12で冷媒から高温熱媒体に放熱された熱のうち、空気加熱器22にて車室内へ送風される空気を目標吹出温度TAOに加熱するために必要な熱に対して余剰な熱が放熱器23にて車室外の空気に放熱される高温熱媒体流量比となるように、高温熱媒体調整部25、26、28を制御する制御部60とを備える。【選択図】図1
