PURPOSE:To adjust temperature of blown air at each blowing port independently in the air conditioner for automobile which is able to adjust the temperature in a passanger room by a method wherein heated main air and unheated auxiliary air are led respectively to a plurality of air blowing means so that the mixing ratio of the both airs can be changed desirably. CONSTITUTION:The air taken in through a ventilation unit 10 is led through a passage running through a vent blowing port 17 and a passage running through a temperature control auxiliary duct 27 to air conditioning zones Z1-Z4. At this time, the air flowing into the vent blowing port 17 is controlled to have an air conditioning temperature through a temperature regulation damper 15, an air mixing chamber 16 and an air blowing port change-over damper 19, and then sent to the respective air conditioning zones Z1-Z4. On the other hand, the air within the duct 27 does not flow through a heater 14, and therefore, has a low temperature. Accordingly, if respective distribution valves 32-35 for the respective zones Z1-Z4 are adjusted selectively, cool air flows into the zones Z1-Z4 to lower the temperature therein. This construction is effective for a selective adjustment of temperature in the respective zones. |
