む。 First, a case will be described in which two occupants are seated in the front seats of this vehicle during a high temperature state in the vehicle interior, where the vehicle interior temperature is 5° C. or more higher than the set temperature. At this time, since the vehicle interior is in a high temperature state, when the air conditioner switch is turned on at the same time as the start of operation, the microcomputer 12 to which a stabilized voltage is supplied from the stabilized power supply circuit becomes operational. Then, the calculation process starts from the start step 100 in FIG.
After proceeding to the initial setting routine 200 and performing various initial settings, the process proceeds to the blower speed control calculation routine 300.

従つて、ブロワモータ1aは高速回転される。 In this blower speed control calculation routine 300, the room temperature Tr and set temperature Ts are input in a temperature input step 301, and the process proceeds to a deviation calculation step 302 to calculate the deviation ΔT. At this time, since the interior of the vehicle is in a high temperature state, the deviation ΔT becomes a value of 5° C. or more. Therefore,
The air volume W determined in the next air volume setting step 303 becomes the maximum of approximately 370 m 3 /h. Then, the process proceeds to the next rear cooler determination step 304, but if the rear cooler switch 8 is turned on at this time, the determination becomes YES, and the process proceeds to the output step 306, where the air volume W determined above, that is, approximately 370 m 3 /h is reached. A corresponding command signal is issued to the motor drive circuits 14 and 15, and one calculation process of the blower speed control calculation routine 300 is completed.
Therefore, the blower motor 1a is rotated at high speed.

The opening/closing angle of the air mix damper 1d is controlled in accordance with the deviation ΔT at that time, and calculation processing for turning on the compressor and blowing out cold air is executed, and the flow advances to the next blowing direction control calculation routine 500. In this blowing direction control calculation routine 500, first, the operating amount found in the wind direction changing plate group position setting step 501 is the maximum since the deviation △T is a value of 5°C or more.

手席に集中的に吹出させる。 Then, the next step 502 is to determine air flow toward the passenger seat.
However, since a passenger is seated in the front passenger seat, the determination becomes YES, and the flow advances to step 503 for blowing out the air from the driver's seat and front passenger seat, where the actuators 16 and 1 are
A command signal is issued to 7 to drive the actuator so that each has a stroke of 20 mm, and blows air intensively to the driver's and passenger's seats.

ルーチン300にもどる。 Next, the process proceeds to step 505 for determining airflow in the left rear seat direction, but since there are two occupants in the front seat, the determination is NO.
The process proceeds to the next step 508 for determining airflow in the right rear seat direction, but the judgment is also NO, and the process proceeds to steps 506 and 509 for commanding a constant airflow in the left and right rear seat directions, respectively, and sends a command signal for the minimum actuation amount So to the actuators 18 and 19. Air-flow direction control calculation routine 500 drives the actuator so that air from the rear cooler is directed away from the rear seats regardless of whether the rear cooler is in operation or not.
After completing one calculation process, the process returns to the blower speed control calculation routine 300.

The change plate group 2a is directed toward the passenger seat, and the maximum amount of cold air generated by the maximum rotation of the blower motor 1a is blown toward the driver's seat and the passenger seat, thereby performing cooling by concentrated blowing. Note that the amount of air blown out from the rear cooler is zero.

なう。 Thereafter, when the temperature inside the vehicle gradually decreases and the deviation from the set temperature becomes less than 5° C., the air volume W determined in the air volume setting step 303 in the blower speed control calculation routine 300 gradually decreases. Therefore, the amount of cold air blown into the vehicle interior gradually decreases. At the same time, the actuation amount S of the wind direction changing plate group position is also gradually decreased from the maximum value, so that the direction of the airflow is gradually changed from concentrated airflow to avoid the occupant. Then, when the deviation △T between the vehicle interior temperature Ts and the set temperature Tr becomes within 2°C, the air volume W becomes the minimum Wo,
The airflow is approximately 180m 3 /h, and the operating amount of the wind direction changing plate group position is also the minimum value So (approximately 4mm), allowing air conditioning of the entire cabin without providing direct wind to the occupants.
