Abstract: A vehicle air conditioner has an actuator for driving an air mixing door and various mode switching doors. An automatic range and a manual range are set in different operating angle ranges of the actuator. In the automatic range, an air outlet mode is automatically switched in accordance with an opening degree of the air mixing door. On the other hand, in the manual range, a multi-mode or a defroster mode is manually set, regardless of the opening degree of the air mixing door. In the manual range, air is simultaneously blown from all openings such as a face opening, a foot opening and a defroster opening in the multi-mode, and air is blown from the defroster opening in the defroster mode.

Abstract: In an air conditioning apparatus for a vehicle, a double layer flow mode is set when the maximum heating state is set during an air outlet mode where both a foot opening portion and a defroster opening portion are opened. During the double layer flow mode, an air passage of an air conditioning case is partitioned into a first air passage through which inside air flows and a second air passage through which outside air flows, in such a manner that the first air passage communicates with the foot opening portion and the second air passage communicates with the defroster opening portion. When the double layer flow mode is set, the maximum rotation speed of a blower for blowing air is reduced by a predetermined level as compared with an entire outside air mode or an entire inside air mode. Thus, heating capacity for a passenger compartment of the vehicle can be improved.

Abstract: A toothed belt has a plurality of teeth, which are arranged in the longitudinal direction thereof, and cords embedded in a back portion of the toothed belt.

Abstract: An air conditioning apparatus for a vehicle includes an air conditioning case for forming an air passage through which air is blown into a passenger compartment. In the air conditioning apparatus, during a cooling mode for cooling a passenger compartment, an inside/outside air introduction mode is switched from an inside/outside air-mixing mode where both inside air and outside air are introduced into the air conditioning case to an entire outside air mode where only outside air is introduced into the air conditioning case, when an engine of the vehicle is stopped and the cooling load is smaller than a predetermined cooling load. Therefore, air-suction noise from an inside air introduction port is not caused, and the air-suction noise is not noted by a passenger in the passenger compartment even when the engine is stopped. Thus, noise of the air conditioning apparatus in the passenger compartment can be reduced.
