PROBLEM TO BE SOLVED: To perform heat management corresponding to a request when heat radiation request amount is lowered relatively to heat absorption request amount while a heat absorption section absorbs heat and a heat radiation section radiates heat.SOLUTION: A compressor 30 is provided in a first circulation passage 12. When heating request amount is lowered relatively to dehumidification request amount from a dehumidification heating operation state where heat is exchanged between the primary side and the secondary side, heat is absorbed in an outdoor heat exchanger 38 and an evaporator 48 in the first circulation passage 12, heat is transferred from a heat exchange medium in the first circulation passage 12 to a coolant in a second circulation passage 56 by using a first heat exchanger 32 and heat is radiated in a heater core of the second circulation passage 56, a flow rate of the heat exchange medium in the outdoor heat exchanger 38 is lowered and then, a flow rate of the coolant in a radiator 74 in the second circulation passage 56 is increased.SELECTED DRAWING: Figure 1
【課題】吸熱部が吸熱を、放熱部が放熱を各々行っている状態で、吸熱要求量に対して放熱要求量が相対的に低下した場合に、要求に応じた熱管理を実現する。【解決手段】第1循環路12は、コンプレッサ30が設けられ一次側と二次側との間で熱第1循環路12の室外熱交換器38及びエバポレータ48で吸熱、第1熱交換器32で第1循環路12の熱交換媒体から第2循環路56の冷却水への熱移動、及び、第2循環路56のヒータコアで放熱を行っている除湿暖房運転状態から、除湿要求量に対して暖房要求量が相対的に低下した場合に、室外熱交換器38における熱交換媒体の流量を減少させた後に、第2循環路56のラジエタ74における冷却水の流量を増加させる。【選択図】図1
