Car Air Conditioning Systems
The air conditioners found in the car works similarly as like as the air conditioners present in the houses and offices. In simple words, the air conditioning system of a car is the small unit of window air conditioning system. With the passage of time, the air conditions found in the car have got changes, and now the latest models are available, which provide more and comfortable cooling.
In order to understand, how the car air conditioning system operates, it is required to know various parts of this unit. First of all, the most important component which is present in this system is the compressor. The compressor is the central component which emits hoses of both high and low pressures. When these hoses come out, they go inside the condenser and finally to the evaporator. In this system, there are two types of valves like expansion and dryer valves, which are required for the proper functioning of this system.
The function of expansion valves is to regulate the internal temperature of air, and it controls the refrigerant flow inside the system. There are certain anti-freezing agents as well like coolant or condensed gases, which pass through these valves.
The mechanism of a car air conditioning system is quite different from the conventional air conditioners. The car system instead of making the air cool, take out the heat, which is already found in the air. The Freon gas is used in the car air conditioning system which possesses a high temperature. When this gas passes through the compressor, the pressure channels mix it with the fresh air. The total gas mixture due to compression becomes liquid, and then it comes to the dryer. This chamber purifies the gas and sends to the evaporator through an expansion valve. The liquid gas absorbs the heat of the car which is then evaporated from here by the help of a blower or fan. This phenomenon repeats several times in order to make the environment cooler.
If you got certain problems in the car air conditioning system then you need to call a mechanic, since the fixing of this system is not a simple job. However; you can avoid the development of various problems in this system and hence can escape from big hassles. It is better to check the leakage of the car air conditioning system on a regular basis. Leakage takes out all the gas present inside the air conditioner and hence with the passage of time, the system becomes useless. It is also good to check the compressor regularly. It could be done by turning on the car followed by switching on the air conditioner. After that, lift up the bonnet and identify the compressor. If there is no movement in the compressor, it means there is some problem in the switching system. Sometimes refrigerant creates problems like the cooling does not happen in the opened system. If such types of problems are identified, call immediately to an electrician or a mechanic.
