To understand the components of air conditioning system.
Objectives
To understand the control function and operation condition.
To understand the troubleshooting method.
The A/C-Heater system combines heating, cooling, ventilation, dehumidifying. The heating system can be made
simply as is utilized the heat generated by the engine. In the other hand the cooling system requires more
complicated equipment to create cool air. When air is cooled, the moisture in the air condenses and forms water
droplets that separate from the air. The airflow is controlled by manual type and automatic type.
Full Automatic Temperature Control (FATC) features completely automatic control of discharge air temperature.
FATC also controls the circulation and humidity of the air inside the vehicle.
With FATC, the driver selects the temperature and the FATC functions to maintain that temperature, regardless
of outside temperature changes. A FATC control module controls air conditioning, ventilating, heating, and
defrosting systems. These electronic control systems automatically adjust doors, blower speeds, and
compressor cycling.
