Car AC Compressor working principle

The AC compressor is an essential component of the vehicle's air conditioning system. When you turn on the AC, the compressor begins the process of circulating refrigerant and cooling the air. The compressor works by compressing gaseous refrigerant, which increases its pressure and temperature. This high-pressure gas is then sent to the condenser, where it is cooled and condensed into a high-pressure liquid. The liquid refrigerant then flows through the dryer, which removes any impurities and moisture. Next, the refrigerant passes through the expansion valve, which reduces its pressure and temperature. This low-pressure, low-temperature refrigerant then enters the evaporator, where it absorbs heat from the surrounding air. The now-cooled air is then blown into the vehicle's cabin by the air conditioning system. Without a functioning AC compressor, the entire process of cooling the air cannot happen. If the compressor is damaged or faulty, the AC system will not be able to provide cool air to the cabin. This can result in discomfort during hot weather and decrease the effectiveness of defrosting the windshield. If you suspect an issue with your AC compressor, it is important to have it inspected and repaired by a qualified technician to ensure optimal performance of your vehicle's air conditioning system.

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.
