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.

Find Problem

Inspect air flow problems: If you're experiencing insufficient air flow from your vents, ensure that there are no blockages. Your cabin air filter might be dirty or completely obstructed. While the engine air filter is well-known, the cabin air filter can also impede air flow. Another potential cause is a malfunctioning blower motor. Before jumping to replace the AC compressors, always check the fuse box for air flow issues.

Conduct a comprehensive check: If you're unsure about the problem with your AC system, perform a thorough inspection. This is a cost-effective method that could save you money in the long term. Start by turning on your car's AC and eliminate any other distracting noises. Listen for any abnormal sounds from behind the console panel or within the engine. Additionally, assess the cooling efficiency of the AC. Look out for unusual odors as well, as they could indicate faulty components or blown fuses. Therefore, it's important to inspect the fuses too.

Monitor your AC's temperature: Similar to measuring internal body temperature with a thermometer during a fever, diagnosing potential issues with your car's AC compressor requires checking its temperature. Specifically, pay attention to the AC compressor clutch. While the AC is running, locate the compressor and identify the clutch, which appears as a small circular gear responsible for engaging the compressor belt. If the AC compressor clutch remains still despite the AC running, it indicates a problem with the compressor. You can try adjusting the belt tension or opt for a complete replacement of the AC compressor.

Detect refrigerant leaks: Just like a closed brake system in your car, any leaks in the AC system can have a detrimental impact. This can result in temperature fluctuations or even complete failure of the system. Although refrigerant leaks can sometimes be caused by a faulty AC compressor, it is not always the case. AC compressors, like any other car part, can eventually fail. While some are manufactured with the highest quality standards and rarely require replacement, most AC compressors will eventually fail.
