How to solve the high thermal noise of the air conditioner

The reasons and solutions for the high thermal noise of the external mechanism of the air conditioner are as follows:

1. The reason for the high noise of the air conditioner:

1. The installation of the outdoor unit bracket is not level, or the fixing screws of the combined bracket are not fastened in place and deformed, which will cause the bottom foot of the outdoor unit to be uneven, at this time, the outdoor unit bracket should be rearranged, and the level should be adjusted or the fixing screws of the bracket should be tightened.

2. The force on the screws at the bottom of the outdoor unit is uneven, and the fastening screws of the bottom plate are loose, and the vibration should drive the beating of the chassis to cause noise when the compressor is running. With a wrench.

Tighten the foot screws, and at the same time tighten them evenly and forcefully, it is strictly forbidden to tighten one of the screws in place first, which will produce uneven fixing force.

3. If the installation position of the outdoor unit is improper, first find out the wall structure, such as precast concrete, and the indoor side is mostly an office space, or a bedroom, study, etc., which is relatively hollow, and the indoor will produce a roundabout surround sound, which is a building structure.

and the effect of decoration in the house, this phenomenon is an objective factor condition.

Second, the solution to the noise of the outdoor unit of the air conditioner:

1. If you buy a new air conditioner, you can directly return or exchange it for a new one, which is the right of the consumer.

2. If the air conditioner is used for a long time and the noise is generated, you can check whether the bracket of the external unit is loose, the compressor will vibrate when the air conditioner is running, and the noise will be generated if it is loose.

3. If the external unit of the air conditioner is used for a long time, you can check whether the external unit has entered a foreign object, causing the fan blades to scratch the foreign body and produce noise. Removing the foreign object will solve the problem.

4. The fan of the air conditioner used for a long time causes friction and noise when rotating due to the lack of lubricating oil, and only needs to add lubricating oil again to solve the problem.

5. If the noise of the air conditioner comes from the sound of the compressor working, you need to pay attention to whether the sound is normal, if it is abnormal noise or the sound is very loud, stop working immediately, and ask a professional maintenance master for maintenance.

What's going on with the loud external heating unit of the air conditioner? Hear what the repairman has to say.

1. The reason for the noise of the air conditioning heating outside unit is too large - the wind speed 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. However, if it is a ** air conditioner, the indoor unit is hidden in the ceiling, and there is only a small air outlet in the visible part, which is both beautiful and comfortable, and generally does not cause indoor noise problems.

2. The reason for the noise of the air conditioning heating external unit - the air conditioning panel is loose

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 reason for the noise of the outdoor unit of the air conditioner heating - the installation of the indoor unit of the air conditioner is unstable

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. The reason for the noise of the air conditioning heating outside unit - compressor

Air conditioning compressor This is also one of the most important air conditioning noise, the noise value of the compressor is too large, which will also affect the use and rest of our normal users.

Workaround:

When the air conditioner is noisy, you can ask the maintenance personnel to check the overall condition of the air conditioner, strengthen the vibration damping foundation of the fan, replace the failed shock absorber, check the impeller, bearing, and balance of the fan, and repair or replace it in time if there is damage. Reduce the air supply speed and avoid excessive wind speed adjustment when in use, which will effectively solve the noise problem of the air conditioner.

The reason why the air conditioner heating outside the unit is loud:

1. Aging of compressor.

When the air conditioner is aging, the compressor will produce vibration sound when working, and some of the sound may be loud and even affect people's rest.

2.The air conditioner panel is loose.

When the air conditioner is used for a long time, due to various reasons, the panel of the air conditioner is easy to loosen, so the vibration generated during the operation of the air conditioner will make the panels rub against each other and produce noise.

3.Instability of the indoor unit of the air conditioner.

The installation of the indoor unit and the connection of the outdoor unit will also have an impact. If the installation of the indoor unit is not stable enough, when the outdoor unit is running, the copper pipe is connected with the indoor unit; If it is not stable enough, the indoor machine will be affected by the compressor, which will cause the indoor unit to resonate.

Maintenance of air conditioning heating unit

1. Cleaning of the outdoor unit of the air conditioner: Check whether the machine is running normally, open the shell, put the water absorption device at the bottom of the air conditioner, dilute the agent and rinse with the special cleaning machine for air conditioning, and at the same time comb the fins with aluminum fin comb, sterilize and disinfect with the air conditioner steam machine, and finally install and restore.

2. Maintenance of the outdoor unit of the air conditioner: When using the air conditioner, please do not place any shields outside the outdoor unit, which will affect the heat dissipation effect of the air conditioner and lead to poor use of the air conditioner.

1. The installation of the outdoor unit bracket is not horizontal.

Solution: The installation of the outdoor unit bracket is not horizontal, or the fixing screws of the combination bracket are not fastened in place and deformed, which will cause the bottom foot of the outdoor unit to be uneven, at this time, the outdoor unit bracket should be rearranged, and the level should be adjusted or the fixing screws of the bracket should be tightened.

2. The force on the screws at the bottom of the outdoor unit is uneven.

Solution: Loosen the foot fixing screw of the outdoor unit again, tighten the foot screw with a wrench, and tighten it evenly at the same time, it is strictly forbidden to tighten one of the screws in place first, which will produce uneven fixing force.

3. The installation position of the outdoor unit is improper.

Solution: First of all, find out that the wall structure, such as precast concrete, and the indoor side is mostly office or bedroom, study, etc., is relatively hollow, and the indoor whirlwind surround sound will be generated, which belongs to the architectural structure and the interior decoration effect of the house, and the phenomenon is an objective factor condition.

It is necessary to determine the appropriate method for specific noisy situations.

Generally speaking, the noise of the outdoor unit during the operation of the split air conditioner is caused by the abnormality of key components such as the fan and motor, or the abnormality of the system.

Multiple key state parameters should be measured at the same time during the normal operation of the air conditioning system, and the possible fault causes should be judged and corresponding solutions should be found according to the changes of these key state parameters.
