A/C Compressors for Cars

The A/C compressor is the driving element of the cold A/C loop and is also the most technically complex component.

There are Three main car compressor technologies:

1.Piston-Type Compressors
The piston type is the most common. This type contains swash plate technology and wobble plate technology.

2.Rotary-Type Compressors
Rotary-type compressors main axis of the rotor coincides with the center.

3.Scroll-Type Compressors
Scroll-Type Compressors dislocation creates pressure to achieve high-speed rotation.

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.
