VENTILATION SYSTEM
id071100001000
Outline
• The ventilation system adjusts the temperature or vent mode of the airflow sent from the blower unit.
Function
• The ventilation system adjusts the airflow temperature by changing the position of the air mix door.
• The ventilation system adjusts the air vent mode by changing the position of the airflow mode door.
Head-cold feet-warm function
-
• When the airflow mode is set to BI-LEVEL and the airflow temperature setting is near medium temperature, the airflow is divided into airflow passing through the heater core and airflow not passing through the heater core.
-
― Airflow passing through the heater core: Air flows to front heat, rear heat
― Airflow not passing through heater core: Air flows to center vent, side vents
• Warm air flows from the front heat air vents and comparatively lower temperature air flows from the side air vents.
• When the airflow temperature setting is near MAX COLD, MAX HOT, the airflow is not divided at the airflow mode door and there is no difference in airflow temperature from each air vent.
Construction
• The ventilation system consists of the following parts.
Operation
Air mix door
-
Full-auto Air Conditioner
-
1. The air mix actuator operates according to the temperature setting dial operation or the automatic control of the climate control unit.
2. The air mix door opens and closes in the COLD and HOT directions in conjunction with the air mix actuator operation.
3. The airflow volume transferred from the evaporator to the heater core changes by the opening and closing of the air mix door, and the temperature of the air which passes the heater core is adjusted.
-
Manual air conditioner
-
1. The air mix wire operates by operating the temperature setting dial of the climate control unit.
2. The air mix door opens and closes in the COLD and HOT directions in conjunction with the air mix wire operation.
3. The airflow volume transferred from the evaporator to the heater core changes by the opening and closing of the air mix door, and the temperature of the air which passes the heater core is adjusted.
Airflow mode door
-
Full-auto air conditioner
-
1. The air mix actuator operates according to the MODE dial operation or automatic control of the climate control unit.
2. The airflow mode main link operates in conjunction with the airflow mode actuator operation.
3. The airflow mode door opens and closes in the VENT, BI-LEVEL, HEAT, DEF/HEAT, or DEFROSTER directions according to the airflow mode main link. The air vent changes by the opening and closing of the airflow mode door.

1. The airflow mode wire operates by operating the MODE dial of the climate control unit.
2. The airflow mode main link operates in conjunction with the airflow mode wire operation.
3. The airflow mode door opens and closes in the VENT, BI-LEVEL, HEAT, DEF/HEAT, or DEFROSTER direction in conjunction with the airflow mode main link. The air vent changes by the opening and closing of the airflow mode door.
-
• The airflow distributed by the airflow mode door passes through the ducts and flows from each air vent shown in the figure to the cabin.
