We will discuss the basic working principles of a vehicle air conditioning system.

The motor-vehicle air conditioning system works on the reverse Brayton or Rankine cycle. Like all air conditioning systems, the aim of the motor vehicle air conditioning system is to control the temperature and humidity of the atmospheric air and circulate this through the interior. The motor vehicle air conditioning system consists of a refrigeration system, air circulation and distribution system and a control system. The refrigeration system cools down the air which include many other parts like compressor, condenser etc. The air circulating system circulate this cooled air into the vehicle which include blower, air duct etc. The controlling system used to control the temperature of the car by sensing it and control the refrigerating system.

In this module you will learn:

• Air conditioning system principles.
• Air conditioning system components.
• Correct application of lubricant and refrigerant for the different components.
• Accident related air conditioning issues.
