Why Is the Car Air Conditioning Compressor So Noisy?

[Gutierrez]

Reasons for a noisy car air conditioning compressor: 1. Damaged compressor electromagnetic clutch; 2. Severe internal wear of the compressor. The compressor frequently operates under high load, shifting from low to high speeds, which places high demands on the electromagnetic clutch. Additionally, the electromagnetic clutch is usually installed close to the ground and often exposed to rain and dirt. When the bearings inside the electromagnetic clutch are damaged, abnormal noises can occur. The car air conditioning compressor is the heart of the car's air conditioning refrigeration system, responsible for compressing and transporting refrigerant vapor. Compressors are divided into two types: fixed displacement and variable displacement. Based on different working principles, air conditioning compressors can be categorized into fixed displacement compressors and variable displacement compressors.
