Last week, the people of guangdong had a feeling of living in a fairyland, and the air was wet and covered with a fog everywhere, and it was not known how many car owners had experienced such a situation: there is always a layer of water on the front windshield, which affects sight and the safety of the vehicle. Because the temperature outside the car is lower than inside it, the water vapour in the car forms the vapour on the glass, at which point the brother will turn on the air conditioner to lower the temperature in the car and remove the vapour。
No, a honda odyssey owner also removed the steam in the same way, but when he turned on the air conditioner, he heard the sound of a “single” on the head. At this point, most would consider the air conditioner to be malfunctioning, but the owner sent the car to the maintenance plant for inspection and the master told the owner that the air conditioner was okay and normal. Automobile air conditioners are normal. Why do you always hear the sound of a tungsten when you drive them
So where's this noise coming from
We can divide open air conditioners into two types, internal and external。
Much of the internal noise is caused by severe wear and tear from air-conditioning compressors, such as linings, axles, etc., and we can hear an acoustics coming from inside compressors, and for this failure we can only replace new compressors。
External noises may have been caused by malfunctions in certain components, such as compressors, belts, stubs, system pipelines, etc. I've had cases of acoustic noise due to compressor clutch failure, as detailed in my previous article, maintenance of archives — ac compressor failure replacement clutch。
The incident, when the master turned on the air conditioner, found that the noise was not from the air conditioner compressor, followed the position of the compressor and examined the spare parts within the range and finally found the problem, which was caused by damage to the high-wheeler。
What does this have to do with air conditioning
High-heavy wheels are able to automatically adjust the increase in the intensity of the belts according to their varying degrees of flaccidness, and when the air conditioners are activated, the load of the motors increases, the intensity of the driving belts changes in response, and when they do not normally regulate the tightness of the belts, the effect of the high-heavy wheel is “single”。
The lifting of the wheel is a loss element of the vehicle spare parts, and this time the master will replace the new surge will solve the problem of the acoustic noise。
Once the replacement is completed, the failure is resolved perfectly. It is believed that the temperature will increase in the near future and the frequency with which air conditioners will be used will increase, and if you also experience an acoustic noise from the operating air conditioners, it may be useful to note whether parts such as heavy wheels, belts and stubbles have broken down。
