What is an AC Compressor?

The compressor is the heart of the air-conditioning system, responsible for circulating refrigerant and oil through the system. It performs two key functions:

Raising the pressure of the refrigerant so it can absorb and transfer heat efficiently.
Creating low pressure in the evaporator, allowing the refrigerant to vaporize and absorb heat from the cabin.

Types of Auto AC Compressors

There are several types of compressors used in vehicle AC systems:

Two-Piston-Type Compressor – Uses a two-stroke process to compress and circulate refrigerant.
Swash Plate Compressor – Utilizes a rotating plate to drive multiple pistons.
Rotary Vane Compressor – Uses rotating vanes to compress refrigerant.
Variable Displacement Compressor – Adjusts output based on cooling demand.
Scotch Yoke Compressor – Uses a sliding yoke mechanism for compression.
Scroll Compressor – Operates with two interlocking scrolls for efficient compression.

Compressor Repair & Maintenance

Regular maintenance helps extend the life of your AC compressor. Key maintenance tasks include:

Checking the compressor oil level when the system is discharged.
Inspecting and replacing compressor seals to prevent leaks.
