What Causes Compressor Noise?

[ValeriaMarie]

There are mainly two situations that cause compressor noise, which are: 1. If the compressor makes abnormal noises after turning on the air conditioning, it is caused by internal piston wear or damaged valve plates. 2. If the compressor makes abnormal noises without turning on the air conditioning, it is due to damaged compressor bearings. Extended content: 1. The car air conditioning compressor is the heart of the car air conditioning refrigeration system, responsible for compressing and delivering refrigerant vapor. Compressors are divided into fixed displacement and variable displacement types. 2. According to different working principles, air conditioning compressors can be categorized into fixed displacement compressors and variable displacement compressors. 3. Based on different working methods, compressors can generally be divided into reciprocating and rotary types. Common reciprocating compressors include crankshaft connecting rod type and axial piston type, while common rotary compressors include rotary vane type and scroll type. 4. According to different working principles, air conditioning compressors can be categorized into fixed displacement compressors and variable displacement compressors.
