How to Deal with Abnormal Noises from Car Air Conditioning?
1 Answers
When there is abnormal noise from the car air conditioning, it is necessary to determine whether the noise is coming from inside or outside the air conditioning system. Abnormal noises inside the air conditioning system are often caused by moisture or air in the refrigerant. When the refrigerant expands, it can produce noise, and the refrigerant can be directly replaced. If too much refrigerant is added, it can also cause abnormal noise, and a small amount can be released appropriately. Below is information about abnormal noises from car air conditioning: 1. Common factors causing abnormal noises from car air conditioning include: Issues with the compressor electromagnetic clutch are a common cause of compressor noise. Since the compressor often operates under high load conditions, shifting from low to high speeds, the demands on the electromagnetic clutch are high. Additionally, the electromagnetic clutch is usually installed close to the ground and frequently exposed to rain and dirt. When the bearings inside the electromagnetic clutch are damaged, abnormal noise occurs. 2. The tension of the compressor drive belt can also cause abnormal noise from the car air conditioning compressor. If the compressor drive belt is too tight or too loose, it can affect the lifespan of the electromagnetic clutch. If the drive belt is too loose, the electromagnetic clutch is prone to slipping. If the drive belt is too tight, the load on the electromagnetic clutch increases. Improper tension of the drive belt can, at best, cause the compressor to stop working, and at worst, lead to compressor damage.
