What's wrong with the loud noise of the car air conditioner

1. Car transportation The reason why the air conditioner is particularly loud is that the throttle valve is polluted or blocked. When the air conditioner is working, the compressor will also work, but the compressor relies on the engine, and turning on the air conditioner will increase the load of the engine. That is to say, the engine increases the opening of the throttle valve and increases the air intake.

2. The following are the specific reasons for the loud noise of the car air conditioner: the throttle valve is dirty or stuck. After the air conditioner works, the compressor will also work, and the compressor is driven by the engine. Therefore, when the air conditioner is turned on, the load of the engine will increase.The engine should increase the opening of the throttle valve to increase the air intake.

3. Failure: Caused by the failure of the blower. The following is an extended information about the solution to the loud noise of the car air conditioner: Replacing the air conditioning pump: The abnormal wear of the air conditioning pump causes a "dede" abnormal sound to repair and go to the 4S store to replace the air conditioning pump.

Is there a noise in the car when the air conditioner is turned on?

The reasons for the noise of the car air conditioner are as follows: the compressor of the car air conditioner is damaged: There are many reasons for the failure of the car air conditioner compressor, including lack of lubrication, hinge wear, inability to compress air normally or air leakage, etc.

There are several reasons for the abnormal sound of the car when the air conditioner is turned on: there is an abnormal sound in the console. It is usually due to the expansion of the refrigerant, and the refrigerant contains water or air. In this case, just replace the refrigerant directly. Another reason is that if too much refrigerant is added, there will also be a strange sound. Appropriate release of some can also solve the problem.

The abnormal sound in the air conditioner is often due to the fact that the refrigerant of the system contains moisture or air. When the refrigerant expands, there will be a sound, which can be replaced directly.

Car air conditioner abnormal sound buzzing

1. There are many reasons for the abnormal noise buzzing sound of car air conditioner, including air conditioner compressor failure, air conditioner belt slippage or wear, air conditioner pipe blockage, electromagnetic clutch failure, air conditioner outlet There are foreign objects, etc. Air conditioner compressor failure: If the air conditioner compressor fails, it will cause abnormal noise or non-refrigeration and heating of the car air conditioner.

2. The car air conditioner is buzzing: there is something wrong with the compressor. When the compressor has the problem of insufficient lubrication of the parts, abnormal noise may occur during the movement. Lubricating oil can be replenished in time.

3. There is a strange sound in the air conditioning channel. The air conditioner filter has not been replaced for a long time, and there are leaves and other foreign objects in the air duct.The air conditioner compressor makes abnormal noise. Poor heat dissipation of the air conditioner, or blockage of the pipeline can cause abnormal noise in the compressor. If the internal pressure of the compressor is too high and the service life of the compressor is reduced, it should be dealt with immediately.

4. The air conditioner filter is dirty: the blockage of the air conditioner filter will lead to insufficient air volume, causing the compressor to overheat and produce noise. Damaged or detached fan: If the fan or wind turbine blade inside the car air conditioner is damaged or deformed, it may cause excessive noise. Similarly, if the fan falls off, it will also cause abnormal noise.

5. The reasons and solutions for the loud noise of the automobile air conditioner compressor. There is a lack of lubricating oil on the compressor, and the parts need to be lubricated. When there is no lubricating oil, the friction between the parts will become louder, so there will be abnormal noises.
