  • Patent number: 7036576
    Abstract: An air conditioning unit and an air blowing unit are connected via an intermediate duct. The air blowing unit is provided on the left side of the air conditioning unit in the forward direction of a car. The air conditioning unit includes an air mix damper and a discharge direction switching damper for switching the discharge direction of conditioned air, each driven by a corresponding actuator via a link mechanism associated therewith. The link mechanism and the actuator are provided on a wall part of the air conditioning unit. From the perspective of the forward direction of a car, the link mechanism and actuator are mounted on a left wall part of the casing of the air conditioning unit. On the other hand, the air blowing unit is provided with an actuator for driving an indoor air/outside air switching damper, and the actuator is mounted to a side of a casing of the air blowing unit facing the air conditioning unit. Thus, the resulting air conditioner is reduced in size to reduce its installation space.
