About Your Aircon
The majority of vehciles manufactruered today are fitted with air conditioning and climate control systems as standard. Most people will be familiar with using air-con in our car. You should also be aware that like other parts of your car, the air-conditioning system also needs regular checking and maintenance. it is working correctly. How does it work?
Your air conditioning system works in a very similar way to a refridgerator. In summary by pressurising refridgerant then allowing it expand it will absorb heat from the air around it. If it is then re-pressurised so it gives off the heat. So by using the heat absorption elements inside the car and the heat disipation outside the car, cooling results. It's all physcis, apparently
While the above explanation is very simp;le, the systems are are slightly more complex. Your Aircon system will have the following parts
- Compresor. This compresses and circulates the refrigerant in the system
- Condensor. As the refridgerant circulates this unit changes the refrigerant from gas to liquid and expels heat removed from the car.
- Evaporator. Transfers heat to the refrigerant from the air blown across it, cooling your car.
- Filter. Removes any mositure or minor impurities that may enter the system.
- Circulating pump. Drives the refridgerant around the system to make the whole process work.
- Refrigerant. The liquid used has changed as the traditional content, Freon, is becoming increasingly more expensive and hard to find. The refrigerant carries the heat.
- Interconnecting pipes
- Cabing, switches and controls
While the most common reason for Aircon not working is loss of refridgerant the cause can be a failure or damage to any of the above elements.
