Auto air conditioning
Auto air conditioning refers to a method of altering the temperature as well as the quality of air. The auto air conditioning is carried out by an auto air conditioner situated I the front part of your car and includes the small vents on either side of the passenger and driver. It is controlled with the knob near the dashboard labeled AC. Using this knob you can decide the type of conditions you want in your car. It could be hot or cool or even a moderation of both. You can also feel the effects of the air conditioner on your feet.
The auto air conditioning AC is made up of five major parts. These parts include the:
The AC system is also comprised of the refrigerant which is the liquid used to transport heat between the various components. The refrigerant is also known as Freon and is specially made for the AC system. Its main role is to absorb and release heat leaving behind cold air. There are two major types of Freon R-12 and R-134a.The R-12 is the old type of refrigerant and has recently been found to cause the depletion of the ozone layer and it has been recommended to replace the R-12 with the less efficient though environmentally friendly R-134a.The AC system is also made up of pipes and refrigerant charging ports and o-rings. Refrigerant is a specially formulated mixture that’s sole purpose for transforming hot air into cold air. It does this by absorbing and releasing heat, ultimately leaving cool air behind.
When you turn on your AC using the knob in your car, the compressor pressurizes the refrigerant thereby raising its temperature. The refrigerant will change state when it absorbs heat from liquid to gas. When the refrigerant passes through the condenser it loses heat. The receiver or accumulator absorbs moisture as well as other contaminants. It absorbs moisture using dessicant. This is an important process because when refrigerant comes into contact with moisture it becomes corrosive and could start eating away at the major components which would be quite costly to replace. This problem is usually encountered when there are undetected leaks in the system. This can be avoided by scheduling regular maintenance by auto service repair companies. The evaporator is responsible for cooling the refrigerant even more and removes moisture as well. Then the blower motor blows cool air out of the ventilation system. Cooling your car’s interior.
You should take your AC for repairs if you notice any changes in its performance and any other issues that you notice affecting your AC. Issues like it not cooling as well as it did before or turning your AC on and noticing that there are no changes taking place in the temperature of the air.
Your technician will do an initial diagnosis of your car before coming up with solutions to whatever problems that your AC may be having. He may recommend recharging your AC if its performance is lower than it should be.
