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
