AIR CONDITIONING DEVICE FOR VEHICLE

PROBLEM TO BE SOLVED: To provide an air conditioning device for a vehicle for miniaturizing size of the whole device, easily providing an air-conditioning state of keeping head cool and feet warm, and capable of restraining cost increase by using a heat exchanger of an ordinary shape.SOLUTION: In an air conditioning device 1 for a vehicle, an evaporator 9 and a heater core 11 are arranged in series along an air flow passage 3, and the air conditioning device includes a foot damper 31 for distributing vertically air-conditioning air air-conditioned by passing through the evaporator 9 and the heater core 11. The heater core 11 is constituted so that a heating medium capable of adjusting flow rate and temperature is supplied from a lower side and discharged from an upper side, and the foot damper 31 is controlled so as to reduce the flow rate of the heating medium supplied to the heater core 11 and to raise the temperature when the foot damper 31 is put in an intermediate position for supplying the air-conditioning air in both upper and lower sides. 【課題】装置全体を小型化するとともに容易に頭寒足熱の空調状態が得られ、かつ、通常形状の熱交換器を用いてコスト増を抑制し得る車両用空調装置を提供する。【解決手段】空気流通路３に沿ってエバポレータ９とヒータコア１１とが直列に配置され、エバポレータ９およびヒータコア１１を通って空調された空調空気を上下に振り分けるフットダンパ３１が備えられている車両用空調装置１であって、ヒータコア１１は、流量および温度が調節可能な熱媒体が下側から供給され、上側から排出される構成とされ、フットダンパ３１が空調空気を上下両方に供給する中間位置とされた際、ヒータコア１１に供給される熱媒体の流量を低減させるとともに温度を上昇させるように制御される。【選択図】図１
