12V For Truck Air Condition Compressor SD7H154373 For WXTK089

The AC compressor plays a crucial role in the air conditioning system of a vehicle. It is responsible for compressing the refrigerant vapor, which helps convert it from a low-pressure state to a high-pressure gas. This compression process increases the temperature of the gas.When the high-pressure gas circulates through the system, it loses heat and releases cold air. This cold air is then pushed through the dashboard vents, creating a comfortable and cool environment inside the vehicle.

Working Principle

The basic working principle of the automobile air conditioning compressor is to suck low-pressure cold gas (usually refrigerant) into the compressor cavity through the driving device, and then compress it into high-pressure and high-temperature gas. Compressors usually use piston or screw compressors. In a piston compressor, the piston moves up and down in the cavity, and the cold gas is compressed by the movement of the piston. In a screw compressor, the screw compresses the cold gas. The compression process of the compressor increases the pressure and temperature of the cold gas. The high-pressure and high-temperature gas will then enter the condenser and be converted into high-pressure hot gas through heat dissipation, then cool and expand through the expansion valve, and finally enter the evaporator to prepare for circulation again. Throughout the process, the compressor provides compression and conversion capabilities and is one of the key components to realize the automotive air conditioning refrigeration cycle.

Reasons why compressors are prone to failure in summer

Air conditioning compressors can fail in the summer due to a variety of reasons. One of the main factors is increased usage during hot weather. The compressor has to work harder to cool the air, putting more strain on its components and potentially leading to failure. Additionally, the increased heat can cause the refrigerant to expand and put extra pressure on the compressor, leading to potential damage.

Another reason for compressor failure in the summer is lack of maintenance. If the compressor is not regularly serviced and maintained, it can become dirty or clogged, affecting its efficiency and eventually causing it to fail. It is important to clean or replace filters, check refrigerant levels, and ensure proper lubrication to keep the compressor running smoothly.

Furthermore, running the air conditioning system improperly can also contribute to compressor failure. For example, if the system is not used regularly or only used at low settings, it can lead to the refrigerant not circulating properly, causing damage to the compressor.

To prevent compressor failure in the summer, it is recommended to have regular air conditioning maintenance performed, including cleaning or replacing filters, checking refrigerant levels, and ensuring proper lubrication. It is also advisable to use the air conditioning system regularly and at the recommended settings to maintain its efficiency and prevent potential damage.
