An air conditioner is both an annealing equipment as well as a cooling equipment, that has been designed to regulate the temperature of a closed room or an area like an automobile. That's why, a conditioning system is also called an HVAC system, heat ventilation and cooling system. You often think "how does automobile air conditioning work?" It is very simple and you can understand the mechanism very well. Basically, refrigerators and air conditioners work on the same principle.

Presently, with increasing technological advancement, air conditioners are being operated with various modus operandi. The air conditioners may use oil, chemicals and gas for the mechanism. Its main function is to regulate the temperature commanded in its thermostat. Besides that, it also helps in cleaning and maintaining the humidification of the room or the car at the comfort level. In vehicles, generally three different kinds of air conditioning systems are used. Each of the them may differ in types but basically the design and the concept are similar. They possess the following mechanical units for the function of the automobile air conditioners.

1. Compressor
Commonly called the heart of AC, it is attached to a belt driven by pump that is affixed to the engine. Its main function is to compress and transfer the refrigerant gas.

2. Condenser
The heat dissipation takes place in this area. It radiates the heat and regulates the temperature for cooling the interior of the car.

3. Evaporator
The heat radiated by the condenser is absorbed by the evaporator. It is the primary unit meant to remove heat from your vehicle. The secondary function is that of de-humidification. Maintaining a proper humid area is very important for apt functioning of the air conditioner and it's regulated by theses humidifiers.

4. Thermostat
The thermostat is the controlling unit of your automobile AC. This is where you regulate the temperature as per your requirement.
