The car's air conditioning system's cooling compressor is located within the engine舱, either on the right side at the bottom or in front. It serves as a core component, responsible for compressing and delivering refrigerant vapor. The compressor can be of two types: fixed-universe compression (fixed power) and variable-universe compression (adjustable power). Fixed-universe compressors deliver a constant output power, while variable-universe compressors adjust their performance based on the system's needs.
When the AC switch is pressed, the compressor begins operation to provide cool air. If the cooling isn't effective, check for noise during operation and inspect the compressor's belts for wear or松动。
