A/C System Description - Overview

The air conditioning system regulates temperature air outlet by mixing cold and warm air in an appropriate ratio. The heater core and evaporator core are installed in the heater unit and has the air mix damper and the mode control damper. The blower unit is composed of a blower motor, the recirculation control damper and the air conditioner filter. The blower unit is connected to a heater unit by the duct integral with the blower unit.

Refrigerant Cycle

Heater Control (Without Climate Control)

The temperature control, air outlet position, and inlet are mechanically switched by connecting between each damper of the heater control, heater unit, and blower unit with the wire cable.

The fan volume can be changed stepwise by changing the fan motor voltage with the fan switch rotation.
