What is the reason for the abnormal noise of the car air conditioner, and what is the cause of the a

The causes of abnormal noise of automobile air conditioners are as follows.

1. Because the electromagnetic clutch is installed close to the ground, the long-term driving of the car will inevitably cause the electromagnetic clutch to be stained with sewage or mud, resulting in damage to the inner bearing, resulting in abnormal noise.

2. The loosening of the transmission belt of the compressor is also one of the reasons for the abnormal noise, the requirements for the electromagnetic clutch in the operation of the automobile air conditioning compressor are relatively high, and the loose transmission belt will cause the load of the electromagnetic clutch to increase, which is easy to cause damage to the electromagnetic clutch, and more serious will burn the compressor.

3. The repeated engagement of the electromagnetic clutch makes the generator insufficient power generation, resulting in insufficient working voltage of the compressor and causing abnormal noise.

4. Maintain a certain clearance, the clearance here mainly refers to the gap between the electromagnetic clutch and the compressor, when the gap between the electromagnetic clutch and the compressor is too large, the impact they produce will increase, and too small will make them interfere with each other, which is the cause of abnormal noise. Summary: The gap distance should be checked every once in a while.

5. There is a lack of lubricating oil inside the compressor, and the lubricating oil should be added appropriately after long-term use of the compressor to avoid abnormal noise or scrap caused by friction.

Hello, according to the abnormal sound can be divided into two situations: one is the metal friction sound emitted when the compressor electromagnetic clutch is engaged, and the other is the squeak sound made by the excessive force of the air conditioning belt, both of which will only appear when the air conditioner is turned on and refueledThere is also a case where the electromagnetic clutch itself is faulty.

Hope mine can help you.

The compressor of the car air conditioner is damaged, due to lack of lubrication, wear of the rotating shaft, failure to compress air normally, or air leakage. When there is a problem with the air conditioning compressor, the air conditioning system in the car will have symptoms of abnormal noise or no cooling.

The air outlet of the air conditioner is blocked.

Fan blades are worn.

Hello, the current number of people consulted may not reply in a timely manner, if it is a vehicle failure problem, it is recommended to use the computer to detect the specific cause of the failure, search for "car master" can consult the car problem at any time, 24 hours ** answer.

The abnormal noise of the air conditioner fan is mainly in the following situations:

1. There is an abnormal sound in the air duct of the air conditioner. The air conditioner filter has not been replaced for a long time, and there are foreign objects such as leaves in the air duct.

2. Abnormal noise of air conditioning compressor. Poor heat dissipation of the air conditioner, or blockage of the pipeline, can cause abnormal compressor noise. The internal pressure of the compressor is too high, which reduces the service life of the compressor and should be treated immediately.

3. The tensioner bearing of the generator or air conditioning belt is faulty, or the function of the tensioner to automatically adjust the belt is lost, resulting in abnormal noise.

Extended content: 1. The blower is a "fan" of the air conditioning system. The blower rotates through the impeller to suck the air inside or outside the car into the blower, and under the action of centrifugal force, it enters the air conditioning box.

By changing the way the input voltage of the blower is used, the speed of the blower is changed, and the amount of air volume is changed.

2. The blower is an important electrical appliance in the air-conditioning system, and the blower control circuit is to meet the needs of passengers for wind speed control.

The abnormal noise of the car air conditioner is due to a problem with the electromagnetic clutch of the compressor

The factors that cause the abnormal noise of the car air conditioner are: the problem of the compressor electromagnetic clutch is a common factor that causes the abnormal noise of the compressor, because the compressor often runs from low speed to high speed under high load, so the requirements for the electromagnetic clutch are very high, and the installation position of the electromagnetic clutch is generally close to the ground, and it is often in contact with rain and soil, and when the bearing in the electromagnetic clutch is damaged, it will produce abnormal noise.

In addition to the compressor electromagnetic clutch, the tightness of the compressor transmission belt may also cause abnormal noise of the automobile air conditioning compressor, and the compressor transmission belt is too tight and too loose will affect the life of the electromagnetic clutch. If the transmission tape is too tight, the load on the electromagnetic clutch will increase.

Improper tightness of the transmission belt will cause the compressor to not work, and it will cause damage to the compressor. In addition, the lack of lubricating oil in the compressor will also cause abnormal noise inside the compressor, and if the lubricating oil is used improperly, it may even cause the compressor to wear and die.

The reasons for the abnormal noise generated by automobile air conditioners are:1Damage to the belt winding wheel of the automobile air conditioning compressor; 2.

compressor failure; 3.The air conditioner filter is not replaced for a long time. Foreign objects in the wheel cavity of the air conditioner may produce abnormal sounds; 4.

When the fan blades are worn out, the fan bearings lose lubrication, and the fan blades are stuck on foreign objects, the car air conditioner will make abnormal noise. How to solve the problem that the car air conditioner has a peculiar smell: The car air conditioner has a peculiar smell because it is not in the habit of using the air conditioner well.

When we parked the car, we did not turn off the air conditioner in advance, but directly turned off the engine, resulting in the evaporation box is very cold, and a large amount of water vapor condenses on the surface, which will be very humid, very cold, a little impurities, bacteria, etc. into the evaporation box, after a period of accumulation, it will become moldy and produce a sour smell. If there is a peculiar smell in the air conditioner in the car, you can go to a 4S shop or repair shop to clean and sterilize the air conditioning system, and thoroughly treat it to remove the odor. Car owners can also clean it themselves, the method is relatively simple:

First, clean the air conditioner lines and air conditioner filters. - Buy your own aircon foam cleaner, aircon filter. -After finding the location of the air conditioning filter, check the location under the windshield in the engine compartment or in the footsteps of the co-pilot, and consult your own brand repair shop for the specific model.

Remove the air conditioner filter and spray the air conditioner foam cleaner into the suction port. - Turn on the air conditioning system to make it circulate, it usually only takes 6 minutes. - Turn off the air conditioner over time, and you can see a lot of sewage flowing out of the air conditioning duct.

At this point, the cleaning process is basically over, and then a natural breeze is blown for a while. - Finally, the installation of a new cabin air filter is complete. After cleaning, you should develop the habit of using the air conditioner frequently, turn off the AC key of the air conditioner before parking, and blow a little natural wind before stopping.

The common factors that cause the abnormal sound of the automobile air conditioner are: 1. The electromagnetic clutch of the compressor has problems: because the compressor often runs from low speed to high speed under high load, the requirements for the electromagnetic clutch are very high, and the installation position of the electromagnetic clutch is generally close to the ground, and it is often in contact with rain and soil, and abnormal noise will be produced when the bearing in the electromagnetic clutch is damaged.

2. Improper tightness of the compressor transmission belt: If the compressor transmission belt is too tight or too loose, it will affect the life of the crack-resistant electromagnetic clutch, and if the transmission belt is too loose, the electromagnetic clutch will be prone to slippage. If the transmission belt is too tight, the load on the electromagnetic clutch will increase.

3. Improper tightness of the transmission belt: it will cause the compressor to not work, and it will cause damage to the compressor. 4. The compressor lacks code and less lubricating oil

If the lubricating oil is not used properly, it may even cause the compressor to wear and die.

The following are the reasons for the abnormal noise of the automobile air conditioner: abnormal sound of the empty compressor: There are many reasons for the abnormal sound of the compressor, such as the electromagnetic clutch of the compressor, the air adjustable compressor is the working part that regulates the rotation, and the compressor is faulty, and the internal wear and tear will produce abnormal noise.

Abnormal sound of electromagnetic clutch: Compressors often run from low speed to high speed under high load, so the requirements for electromagnetic clutches are very high. When the bearings in the electromagnetic clutch are damaged, an abnormal noise is generated.

Excessive wear: Loose compressor drive belts, excessive wear, skewed pulleys, damaged drive belt tensioner bearings. If the transmission belt is too loose, the electromagnetic clutch is easy to slip; If the transmission belt is too tight, the load on the electromagnetic clutch will increase.

The reasons for the abnormal sound of the automobile air conditioner are as follows: according to the different abnormal sounds, it can be divided into two kinds of emotional hall dispersal conditions: 1. The metal friction sound emitted when the compressor electromagnetic clutch is engaged.

2. The air conditioner belt is stressed too much and squeaks. The solution to the abnormal sound of the automobile air conditioner is as follows: 1. The metal friction sound is emitted when the compressor electromagnetic clutch is occluded, and the fault is the lack of refrigeration oil for lubrication inside the compressor.

In this case, it is necessary to first vacuum the refrigerant in the air-conditioning system, add enough refrigerant oil, and then add the refrigerant to make socks, and turn on the air conditioner for a while to fully circulate the refrigerant in the pipeline. 2. The electromagnetic clutch itself is faulty, and the internal bearing is damaged and makes abnormal noises, in which case the compressor needs to be replaced
