Air conditioning compressor: The car air conditioning compressor is the heart of the car air conditioning refrigeration system, responsible for compressing and transporting refrigerant vapor. Compressors are divided into two types: fixed displacement and variable displacement. According to different working principles, air conditioning compressors can be classified into fixed displacement compressors and variable displacement compressors. Compressor classification: 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.
