Can the oil in an automotive air conditioning compressor be changed?
1 Answers
Automotive air conditioning compressors can have their oil changed. Types: Compressors are divided into fixed displacement and variable displacement types. Based on their working principles, air conditioning compressors can be categorized into fixed displacement compressors and variable displacement compressors. Compressor noise levels: The noise generated during air conditioning operation mainly comes from the internal evaporator and the external condenser. National regulations stipulate that for air conditioners with a cooling capacity below 2000W, the indoor unit noise should not exceed 45 decibels, and the outdoor unit should not exceed 55 decibels; for split air conditioners with a capacity between 2500W and 4500W, the indoor unit noise should not exceed 48 decibels, and the outdoor unit should not exceed 58 decibels.
