Abstract
Description
冷却用熱交換器12は、空気流路9内において導入される全ての空気が通過するように立設されており、この冷却用熱交換器12は例えばコルゲート状のフィンとチューブとを交互に複数段積層して形成されチューブの長手方向端にタンクを有するもので、膨張弁14等の他の空調機器と配管15a、15b等を介して接合されて冷凍サイクルを構成している。送風機11と冷却用熱交換器12とは相対的に近接して、送風機11が冷却用熱交換器12の直近上方に配置されている。
加熱用熱交換器13は、例えばコルゲート状のフィンとチューブとを交互に複数段積層して形成されチューブの長手方向端にタンクを有するものであり、かかる加熱用熱交換器13は配管17a、17bを介して例えば走行エンジンの冷却水等の温水が循環している。
一方で、バイレベルモードからベントモードに移行する場合には、図5(b)から図4(b)となる配置変化に示されるように、メインカム42がワイヤーケーブル53により車両後方に引っ張られて、複合機能ドア30を反時計回りに回転させると共に、ピン45が中継カム48のピン摺動部49の内縁面を車両前方に押しつつピン摺動部49内を摺動するので、中継カム48と連結されたインテークドア7を時計回りに回転させる。このような駆動機構40による複合機能ドア30及びインテークドア7への回転動力の伝達は、フットモードからバイレベルモード、デフフットモードからフットモード、デフモードからデフフットモードに移行する場合でも略同様である。
