How a Car A/C Compressor Works
1. Basic Function
The compressor pressurizes low-pressure refrigerant gas from the evaporator, turning it into a high-pressure, high-temperature gas before sending it to the condenser for cooling.
2. Key Components
Compressor Clutch: Engages/disengages the compressor pulley based on A/C demand.
Swash Plate/Pistons (in piston-type compressors): Compresses refrigerant.
Refrigerant Inlet & Outlet: Low-pressure gas enters, high-pressure gas exits.
Solenoid (in variable displacement compressors): Adjusts cooling capacity.
3. Step-by-Step Working Process
(1) Refrigerant Intake
The low-pressure, cool refrigerant gas (from the evaporator) enters the compressor.
(2) Compression
The compressor’s pistons or rotors compress the gas, increasing its pressure and temperature.
Common compressor types:
Piston-Type (Reciprocating)
Scroll-Type (Spiral design, smoother operation)
Rotary Vane (Uses rotating blades)
Variable Displacement (Adjusts output based on cooling needs)
(3) Discharge
The high-pressure, hot gas flows to the condenser, where it releases heat and becomes a liquid.
(4) Clutch Engagement
The electromagnetic clutch connects/disconnects the compressor from the engine belt:
Engaged (A/C ON): Pulley drives the compressor.
Disengaged (A/C OFF): Pulley spins freely, saving engine power.
4. Common Issues Affecting Performance
Low Refrigerant: Prevents proper compression.
Clutch Failure: Compressor won’t engage.
Internal Leaks/Wear: Reduces cooling efficiency.
Blocked Orifices: Restricts refrigerant flow.
5. Importance of the Compressor
Without it, refrigerant cannot circulate, and the A/C system cannot cool the cabin.
A failing compressor can lead to warm air, strange noises, or complete A/C failure.
