How does the noise of the blower come about
The air blower rotates through the impeller, sucks the air inside and outside the car into the blower, and enters the air conditioning box under the action of centrifugal force. The fan speed and air volume can be changed by changing the input voltage of the fan.
Some knowledge about blowers: < br / >
1. The air noise of the air conditioner fan is related to the air volume of the air conditioner. The greater the air volume, the greater the wind sound. This kind of sound is a normal phenomenon, just like the electric fan, the larger the air volume is, the louder the sound of the wind blade is.
2. If the air conditioning fan makes a "harsh" and "buzzing" sound, you can check whether the air conditioning filter has not been replaced for a long time. If the air conditioning filter element is not replaced for a long time, the working environment of the fan will deteriorate, and a large amount of dust will accumulate on the fan impeller, which will affect the dynamic balance of the fan, and the operation should be careful!
3. Switch the internal and external circulation mode of the air conditioner in time. When the car encounters poor air quality on the road during driving, the air conditioner will switch to internal circulation mode to prevent foreign matters such as blades from entering the blower, thus causing friction between the impeller and foreign matters and generating noise during the operation of the impeller.
4. When cleaning the air conditioner, please find a professional to clean it. In the process of cleaning the air conditioner, using cleaning fluid to clean the lubricating oil inside the fan will cause the fan to dry grind and produce noise during operation!
