6SEU14C Car Air Compressor 4F0260805D 4F0260805F For Audi A5 A6L C6 2006-2011 WXAD004

Parameter :

Considered to be the heart of your truck’s air conditioning system, the AC compressor is a pump that moves the refrigerant across the AC system. Since the AC compressor is part of the air conditioning system, many people think that it compresses cold air, but it actually puts the refrigerant under high pressure and the cooling is done by other components in the air conditioning system before cold air reaches the passenger cabin.

Product Description

• Rapid Refrigeration: Thanks to its powerful and robust compressor, the cooling function operates quickly and steadily. It also excels in dissipating heat.
• Stable & Strong Pressure: The air-conditioning compressor is driven by a powerful motor, generating high pressure that is compressed and transmitted to achieve effective cooling.
• Energy Saving & Noise Reduction: The air conditioning compression system helps save fuel consumption, reducing overall fuel costs. Noise and vibration reduction greatly enhance the driving experience.
• Well Tested & Easy To Install: Comprehensive functional testing is conducted prior to delivery. The presence of sufficient frozen oil facilitates easy replacement. No welding, adjustments, or modifications are required.

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.

Compressor Clutch Issues

Compressor clutch issues can cause problems with the functioning of the AC compressor. The compressor clutch is connected to the engine by a belt and pulley and allows the compressor to cycle on and off as needed. This helps to reduce wear on the compressor and improve fuel economy by allowing the engine to disengage the compressor when cool air is not required.

However, there are issues that can arise with the compressor clutch. One potential problem is the failure of the clutch to disengage, causing the compressor to constantly run while driving. Conversely, the clutch may also fail to engage at all, resulting in no operation of the compressor. Both of these scenarios are undesirable.

While it is sometimes possible to repair the clutch, it is generally recommended to replace the entire compressor and clutch unit as a solution. This ensures optimal functioning and performance of the AC system.
