A/C UNIT CONSTRUCTION/OPERATION

BHE071161130T01

## Construction

• An A/C unit with integrated cooling and heater units has been adopted.

1 | Evaporator
2 | Heater core
3 | Expansion valve
4 | Air mix door
5 | Airflow mode door
6 | Evaporator temperature sensor
7 | Power transistor (full-auto air conditioner), resistor (manual air conditioner)
8 | Air mix actuator
9 | Air flow mode actuator
10 | Airflow mode main link
11 | A/C amplifier

## Air Mix Door Operation

• The air mix actuator, installed in the A/C unit, controls HOT or COLD positions, depending on the position of the temperature control dial. As a result, the airflow distribution changes, and the airflow temperature is controlled.

1 | Airflow from blower unit
2 | Heater core
3 | Evaporator
4 | Air mix door
5 | COLD
6 | HOT

## Airflow Mode Door Operation

• The airflow mode actuator move to the VENT, BI-LEVEL, HEAT, HEAT/DEF, or DEFROSTER position, depending on the position of the airflow mode selector switch. As a result, the airflow mode changes.

1 | Airflow from blower unit
2 | Air mix door
3 | Airflow mode door
4 | Evaporator
5 | Heater core
6 | To center vent and side vent
7 | To front heat
8 | To rear heat
9 | To defroster and side demister
10 | VENT
11 | BI-LEVEL
12 | HEAT
13 | HEAT/DEF
14 | DEFROSTER
