What is the reason for the high noise of the indoor unit of the air conditioner?

1. The air speed of the air outlet of the air conditioner is too large. The main noise of the air conditioner is the air outlet of the air conditioner, when the air conditioner is turned on, the greater the wind speed, the noise value of the air conditioner will gradually increase, which is one of the main noise values of the air conditioner.

2. Loosening of the air conditioning panel Loosening of the air conditioning panel. When the air conditioner is used for a long time, the panel of the air conditioner is easy to loosen due to various reasons, so that the vibration generated by the air conditioner during operation will make the panels rub against each other, resulting in noise.

3. Air conditioner internal unit through the fan. When friction occurs or lubrication is poor in the internal machine cross-flow fan, a large friction sound will be generated. The installation of the indoor unit of the air conditioner is not stable.

<> the noise of the air conditioner is high, if the wall-mounted indoor fan motor is not assembled in place with the cross-flow wind wheel and fan bearing, and the friction sound is generated, the assembly position of the three parts is readjusted; If it is caused by poor assembly of the indoor fan motor and the cross-flow wind wheel, the cross-flow wind wheel will be removed, and if the noise is eliminated, the cross-flow wind wheel will be replaced, otherwise the internal fan motor will be faulty, and the internal fan motor will be replaced.

If it is just a few minutes after turning on the machine, the airflow sound is very loud, and gradually decreases to return to normal, this phenomenon should be normal, and the phenomenon is that when the high and low pressure difference of the refrigeration system is not established normally, there will be a more obvious airflow sound, and then it will gradually become normal. Otherwise, it may be that the connection pipe is bent and flattened due to improper installation, and the secondary throttling is generated, or the indoor unit, evaporator, and interface welding slag are blocked, and the evaporator needs to be replaced.

If the air conditioner is in the refrigeration condition, the indoor unit is noisy and the wind speed is adjusted to the minimum, and the refrigerant boiling sound is listened to. If it is determined that it is not caused by the electric control board, then it is necessary to check whether the refrigerant flows into the evaporator, which will lead to severe heat exchange and large boiling. The solution is to fill it with a sufficient amount of refrigerant, so that the fan will run normally and no noise will be generated.

If the air duct system is blocked, or the wall-mounted fixed wallboard is not firm or the wall surface is uneven, there will also be a loud problem, at this time, you only need to clean the air duct system, re-fix the wall-hanging board, or treat the wall-mounted wall to keep the wall-hanging board flat.

Answer: The solution to the high noise of the air conditioner.

1. Fix the air conditioning panel.

The noise of the air conditioner is most likely caused by the loosening of the air conditioner panel, in which case the air conditioner panel needs to be reinstalled.

2. Adjust the position of the air conditioner.

The installation level of the air conditioner unit is unstable, or the fixing screws of the combination bracket are not tightened and cause deformation, which may lead to uneven placement of the air conditioner and high noise of the air conditioner unit, so it is necessary to readjust the position of the air conditioner and place it on the horizontal line.

3. Adjust the indoor fan.

Due to the lack of the motor of the wall-mounted indoor fan, the cross-flow fan impeller and the fan bearing components, the air conditioner will be noisy, and it must be readjusted and assembled to the corresponding position.

There may be several reasons for the high noise in the air conditioner:

1.Fan noise: The fan inside the air conditioner may increase the noise due to long-term use or dust.

2.Compressor noise: The compressor in the air conditioner may increase due to aging or improper use.

3.Pump noise: The water pump in the air conditioner may increase due to improper use or aging.

4.Improper installation: If the air conditioner is not installed properly, such as unstable installation or friction with the wall, it will also lead to increased noise.

5.Loose pipes: The pipes in the air conditioner may increase due to loose or old suspicions, resulting in increased noise.

If the air conditioner is too noisy, it is recommended to contact professional maintenance personnel for inspection and maintenance in time.

1. Reason: The air conditioner has a silent mode or a silent type that does not turn on the air conditioner, so it will make some relatively loud noise. There is also a situation that the air conditioner at home may be used for a long time, and at this time, there are some cards in the position where the blades of the air conditioner are connected, so there is noise.

The solution is as follows: Second, the solution: If there is noise because the air volume is large, you can try to use the air conditioner remote control to turn the air volume smaller, so that the noise is smaller.

However, if the noise is still relatively loud, you can turn on the silent mode of the air conditioner so that there will not be too much noise. If the blades are stuck because the air conditioner has been used for a long time, you can apply some lubricating oil to the air conditioner blades at this time, so that the air conditioner can make less noise.
