AEEAC501-Repairing vehicle air conditioning system
Introduction
Air conditioning system facilitates the removal of heat from inside the vehicle. Driver and passenger comfort is the primary purpose of the heating, ventilation, and air-conditioning system, often abbreviated HVAC.
The heater is also needed in cold climates to prevent freezing or death. The principle applied is that heat is removed by conduction and convection. An evaporator which is cold absorbs the heat from the air that is passed through it and then cold air is forced out through the vents inside the car by the blower motor.
