What Causes the Compressor to Fail?

[KathrynLee]

The causes of compressor failure are: 1. Poor internal lubrication of the compressor; 2. Unclean air conditioning system; 3. Excessive refrigerant or lubricant in the system; 4. Slippage of the compressor's electromagnetic clutch leading to excessive friction temperature; 5. Insufficient power configuration of the compressor. The function of the compressor is to compress and transport refrigerant vapor. Its working principle is: it sucks in low-temperature and low-pressure refrigerant gas from the suction pipe, compresses it through the operation of the motor driving the piston, and then discharges high-temperature and high-pressure refrigerant gas to the discharge pipe, providing power for the refrigeration cycle. Types of compressors include: 1. Fixed displacement compressor: The exhaust volume increases proportionally with the increase of engine speed; 2. Variable displacement compressor: Automatically adjusts power output according to the set temperature.
