Here’s a concise 6-point explanation of automotive A/C compressor operation :

1.Refrigerant Intake

Draws in low-pressure gaseous refrigerant (35-50 psi) from the evaporator

Contains suction reed valves that prevent backflow

Refrigerant enters at about 0-10°C (32-50°F)

2.Compression Process

Mechanically pressurizes refrigerant to 150-300 psi

Raises temperature to 70-100°C (160-212°F)

Different methods: pistons (reciprocating), scrolls (orbital), or vanes (rotary)

3.Refrigerant Discharge

Expels high-pressure hot gas through discharge valves

Flows to condenser for liquefaction

Typical discharge temperature: 80-120°C (176-248°F)

4.Clutch Operation (Belt-Driven Types)

Electromagnetic clutch engages when cooling needed

Cycling clutch models turn on/off to maintain pressure

Modern variable displacement models run continuously

5.Lubrication System

Uses PAG or ester oil (typically 150-200ml)

Oil circulates with refrigerant throughout system

Critical for preventing metal-on-metal wear

6.Protection Mechanisms

Low-pressure cutoff (below 20 psi disengages)

High-pressure switch (over 400 psi protection)

Thermal overload safeguards against seizure
