20110005717 | VEHICULAR AIR CONDITIONING APPARATUS AND TEMPERATURE CONTROL METHOD PERFORMED THEREBY - Air is supplied to the interior of a casing from first and second blower units, such that cool air that has been cooled by an evaporator and warm air that has been heated by a heater core are mixed together and blown out toward a front seat side and a rear seat side of the vehicle, respectively. At this time, a temperature control damper, which adjusts the temperature of air that is blown into the vehicle compartment, causes a flow of warm air having undergone heat exchange in the heater core to be deflected toward a direction where the evaporator is installed. Mixing of the warm air and the cool air can thus be carried out suitably by causing the flow of cool air, which has undergone heat exchange in the evaporator, and the flow of warm air to be oriented in mutually opposite directions. | 01-13-2011 |
