[StBrynlee]

The reasons for smoke coming from a car's air conditioning are excessive power of the air conditioning or damage to the air intake. Here are the relevant explanations: 1. Excessive power of the air conditioning: The cooling effect is noticeable, and the white smoke is the crystallization of water, which is normal. 2. Damage to the air intake: The car's air conditioning compressor is the heart of the car's air conditioning refrigeration system, responsible for compressing and delivering refrigerant vapor. Compressors are divided into two types: fixed displacement and variable displacement. According to different working principles, air conditioning compressors can be categorized into fixed displacement compressors and variable displacement compressors. 3. Additional information: The car's air conditioning system is a device designed to cool, heat, ventilate, and purify the air inside the vehicle compartment. It provides a comfortable environment for passengers, reduces driver fatigue, and enhances driving safety. The air conditioning system has become one of the indicators of whether a car is fully equipped with necessary functions.
