What Causes the Air Volume of Car Air Conditioning to Fluctuate?
1 Answers
Car air conditioning air volume fluctuations are caused by the cooling fan constantly starting and stopping. Here are the relevant explanations: 1. Electromagnetic switch: An electromagnetic switch is at work, causing the air conditioning compressor to operate after being energized. The adsorption force generated during this process creates certain noises and slight vibrations. 2. Compressor: The car air conditioning compressor is different from household air conditioning compressors. Household compressors operate directly when powered, while car compressors are driven by a belt after being energized and adsorbed. Therefore, when the cooling switch is turned on, electromagnetic adsorption consumes electrical energy, and the belt-driven pump head (car air conditioning compressor) also consumes engine power.
