What is the reason for the loud sound of the air conditioner?

1.It may be a collision of the copper pipe inside the external machine. 2.

Compressor collides with copper pipe3The bracket used to secure the compressor underneath is loose. You can see this place from underneath the external machine.

4.Damage to the inside of the compressor 5The shaft of the fan is broken.

The noise of the outdoor unit mainly comes from the loose fan blades of the outdoor unit, the loose compressor, and the dust falling of the fan blades (eccentric fan blades). Generally, the noise** is identified before making a decision. Tighten the loose ones and clean up the fallen ash.

If there is noise inside the compressor, the compressor can only be replaced, otherwise it will be used.

First, the sound of the air conditioner is relatively loud, what's going on.

1. After turning on the air conditioner, the outside unit of the air conditioner will always be running, if the noise is relatively large, generally speaking, because the wind speed of the air conditioner is relatively large, so the sound of its external unit will slowly become louder, which is also the most important noise**, that is to say, its air outlet.

2. The noise of the air conditioner is also very related to the loosening of its panel. Due to various reasons, such as the action of external forces, the panel of the air conditioner is loose, and there will be a large vibration when it is running, which will lead to friction between the panels and noise.

3. If the indoor unit of the air conditioner is not installed reasonably, because the external unit and the internal unit of the air conditioner are connected, there will be a lot of noise when using it. The installation of the indoor unit is not stable enough, when the outdoor unit is running, there is a copper pipe connected to the indoor chassis, because it is not fixed, it will affect the operation of the outdoor unit, which will produce resonance.

4. The compressor of the air conditioner is also noisy, if the noise value of the compressor is relatively large during operation, it will also affect the external unit of the air conditioner and make a lot of noise.

Second, how to solve the loud sound of the air conditioner.

1. If the sound of the outdoor unit of the air conditioner is relatively loud due to the non-standard installation, such as the bracket is not firm, or the installation of the external unit is unstable, it is necessary to fix the external unit again, and the indoor unit should also be installed reasonably.

2. If it is because of the vibration of the compressor when it is working, resulting in a collision and friction, it may be necessary to replace the relevant parts of the compressor, or directly put a shock-absorbing rubber pad directly under the external machine, which can also effectively solve the noise problem.

The reason why the outdoor unit of the air conditioner is noisyReason 1: The air conditioner panel is loose.

After a long period of use, the air conditioner panel will loosen due to a variety of reasons, and the loose panel will rub against each other with the vibration generated by the operation of the air conditioner, resulting in noise, the greater the degree of loosening of the panel, the greater the volume of noise.

Reason 2: The installation of the air conditioner is unstable.

The indoor unit and the outdoor unit of the air conditioner are connected to each other, if the installation of the internal unit is unstable, the vibration generated by the operation of the external unit will be transmitted to the internal unit through the copper pipe, resulting in the resonance between the internal unit and the external unit, resulting in strong noise.

1. The wind speed of the air conditioner is relatively large, so the sound of its external unit will gradually become louder, which is normal.

2. The panel of the air conditioner is loose, and there will be a lot of vibration when it is running.

3. The copper tube is connected to the indoor chassis, because it is not fixed, which will produce resonance.

In this case, the fan is broken, the rotation is eccentric, and the sound of the fan blade is blowing, so it is good to find a professional maintenance air conditioner master to check and replace a new fan blade.

It is normal for the external unit of the air conditioner to be louder when heating than when cooling.

Because when the air conditioner is heating, the outside will have a defrosting state. During the defrosting process, both the internal and external fans will stop running. Only the compressor of the external unit is rented in operation and. However, if the compressor and fan of the external unit are not running, it will be difficult to stare, resulting in the uneven operation of the external unit.

And there are rubber pads underneath the compressor. There is shock absorption during operation. However, if the ruler flutters unevenly, it will increase the noise. Therefore, the air conditioner is more noisy when heating than when cooling.

And the noise of the air conditioner when heating is not always noisy. He is intermittently loud. This phase lengthens as the outside temperature increases. That is, the higher the outside temperature, the longer the interval between his defrosting states.

Kiss Glad to answer for you: What is the reason why the air conditioner is very loud Answer: "Kiss 1, the main noise of the air conditioner outlet is the air outlet of the air conditioner, when the air conditioner turns on the wind speed, the noise value of the air conditioner will of course 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. The installation of the indoor unit of the air conditioner: The installation of the indoor unit of the air conditioner and the connection of the outdoor unit also affect the timing, use and noise of the air conditioner. If the installation of the indoor unit is not stable enough, when the outdoor unit is running, the copper pipe is connected to the indoor unit, and the indoor unit is not stable enough, it will be affected by the compressor, resulting in the resonance of the indoor unit.

4. Air conditioning compressor Air conditioning compressor This is also one of the best air conditioning noise, the noise value of the compressor is too large, which will also affect the use and rest of our normal users. 1. The noise caused by non-standard installation is common such as loose feet, unstable fixing parts of the bracket and uneven installation of the external machine. The noise caused by such factors is generally tightened to the external unit, and the noise can be discharged by leveling.

2. The outer casing is loose and causes the joint to collide with each other and vibrate during work to produce noise, and the fault part is judged first and then fastened. 3. The vibration of the press during work causes the collision noise between the external machine pipelines, and the fault can be eliminated by adjusting the mutual protection distance between the external machine pipelines or installing shock-absorbing cement. Noise when the press is working:

One is because of the components. It is common to see a press jam or a damaged starting capacitor of the press. Damaged spare parts can be replaced.

The other is that the performance of the press is poor, and it produces a low-frequency vibration hum when working. It can be eliminated by adjusting and replacing the shock-absorbing rubber pad of the press foot, wrapping soundproof cotton, etc.

The reason may be that the external unit is not properly installed, which can be solved by tightening the bracket and adjusting the angle of the fuselage; It may be that the vibration of the air conditioner outdoor unit is caused by long-term use, resulting in the loosening of the anchor bolts, which can be solved by tightening the bolts; The reason may be that the outer panel of the air conditioner is vibrating, which can be solved by tightening the screws; The possible reason is that there is dirt and dirt in the external unit of the air conditioner, and there are foreign objects in the fan blade card, and cleaning the external unit on schedule can effectively solve this problem; This may be due to noise generated by compressor operation, which can be prevented by adjusting the pipe spacing appropriately or by using shock-absorbing and sound-insulating materials.

The air conditioner is loud outside, and it may be an indirect effect caused by the internal unit:

Neglecting the firmness of the indoor unit installation will cause the copper pipe connecting the internal and external units to be affected and cause vibration and noise.

When the air conditioner is used in the internal unit, the air volume is too large, which will also cause the noise of the air outlet and affect the sound of the external unit. Therefore, setting the temperature and air volume that is suitable for the space is also a feasible way to reduce the loud noise produced by the air conditioning machine.

In addition, the voltage of the air conditioner is unstable, which causes the compressor to work overload, which will also lead to the increase of sound and affect the user's rest. When installing the air conditioner, it is also necessary to pay attention to the selection of the location, it is more appropriate to fix it on the wall, not to install it on the window frame, and to avoid unnecessary noise caused by this association.

The loud sound of the air conditioner can be caused by the following reasons:

1.Compressor noise: The compressor in the air conditioner is one of the core components of the air conditioning system, which is responsible for compressing the refrigeration agent and feeding it into the indoor unit. If the compressor is aged or damaged, noise will be generated.

2.Fan noise: The fan in the outdoor unit of the air conditioner is used to dissipate heat and transmit the amount of hot air from the indoor unit to the outdoor unit. If the fan is dirty or the propeller blades are damaged, it will cause increased noise.

3.Vibration and noise: The installation of the air conditioner is unstable or the parts are loose, which will lead to vibration and noise. This can be caused by improper installation or after long-term use.

4.Pipe noise: The air conditioner is connected to the indoor unit through a pipe, and if the pipe is loose or rubbed, noise will be generated.

In order to solve the problem of high noise of the air conditioner outside unit, the following measures can be taken:

1.Regular maintenance: Regularly clean and maintain the air conditioner's outdoor unit, including cleaning the fan, replacing damaged parts, etc., to ensure its normal operation.

2.Stable installation: Ensure that the installation of the air conditioner is firm and stable, and reduce the generation of vibration and noise.

3.Sound insulation measures: Sound insulation materials, such as acoustic panels or acoustic cotton, can be installed around the outdoor unit of the air conditioner to reduce noise transmission.

4.Seek professional help: If the above methods do not work, it is recommended to consult a professional aircon repairer, who can check and fix the possible problem.

There are many reasons for the noise of the air conditioner outside unit, such as non-standard installation, loose feet, unstable bracket fixing parts, and uneven installation of the outdoor unit.
