Working principle
In a closed AC system, the cooling process of freon in the evaporator is a result of a significant pressure change. The high-pressure liquid freon moves through a narrow opening, which causes it to atomize and cool rapidly. The compressor's role is to pump the refrigerant (freon) from the low-pressure circuit (condenser radiator) to the high-pressure circuit (evaporator radiator), simultaneously compressing it and increasing its temperature. The freon is then cooled and converted to a liquid state in the condenser before reentering the system. The AC compressor is commonly referred to as the "heart" of the system, underscoring its vital role in the proper functioning of the air conditioner. Consequently, the compressor experiences a significant load as it operates.
 
 
 
 
Occurrence Of Problems

Many car owners who have not experienced air conditioner repairs might not realize how costly the procedure can be. This is why it is important to highlight the primary mistakes that can lead to numerous issues with the car's AC compressor.

 
1.Neglecting regular maintenance of the AC system: One common mistake that car owners make is ignoring the annual maintenance procedure for their AC system. This can lead to issues with freon leakage, as rubber hoses in the system have a tolerance of up to 10% for leakage due to their porosity. By not refilling the AC system regularly, the refrigerant levels can drop significantly over time, affecting the cooling efficiency and putting extra strain on the compressor.

 
2.Not using the air conditioner in winter: Another mistake is not turning on the air conditioner for preventive purposes during winter. Running the AC system periodically during the winter helps to lubricate the internal components and maintain the tightness of the system, preventing refrigerant leakage and corrosion. While the AC may not work at subzero temperatures outside, it can be turned on in a warm room such as a service station, car wash, or covered parking. This simple operation takes around 15 minutes and can have a positive impact on the longevity of the AC system.
 
3.Installing a fine-grained mesh in front of the radiator-condenser can hinder the radiator's cooling capacity. Consequently, the efficiency of the AC system decreases, causing the car compressor to operate under a heavier load. As a result, the compressor and several components of the AC system endure more strain, leading to a reduction in their lifespan. Similar issues can arise when debris accumulates in the radiator-condenser, particularly after spring when it becomes congested with fluff. It is common for individuals to overlook proper maintenance of the AC system and opt for inexpensive alternatives instead of seeking professional help at reputable repair stations. However, professional repair stations possess the necessary equipment, such as charging stations and gas analyzers, to ensure the correct refrigerant is used. Neglecting proper maintenance procedures can result in various problems that prevent the AC system from functioning properly. For instance, using subpar refrigerants that may contain different types of refrigerants can cause compatibility issues with the system's lubricating oil. Consequently, the lubrication effectiveness of the system decreases, and the car compressor's lifespan may be prematurely reduced.
 
4.Inadequate maintenance of air conditioners, based on the principle of cost-cutting rather than professional servicing at recommended specialized service stations, can lead to various violations that may ultimately disable the air conditioner. One such violation is the use of low-quality freon during maintenance, which may contain different types of freon that are not compatible with the oil used in the system. While this mixture might still meet temperature requirements, such as the boiling or condensation point, of the standard R134a freon, it can significantly deteriorate the lubrication system and quickly lead to the failure of the car AC compressor.

By avoiding these mistakes and being proactive in maintaining the AC system, car owners can prevent costly repairs and ensure that their air conditioner continues to function efficiently.
