Is it normal for an air conditioner duct to have a ring? What is the cause of the ringing of the air

It's not that inverter air conditioners are like this, and the two Midea inverter air conditioners in my room at home don't have this problem!! The air conditioner in my hometown was damaged a few days ago, and then someone replaced the pipe and added cold silence, and there was a sound when it was turned on, and the noise was quite loud! It's like a lonely and flowing voice in the tube!

I guess there should be air in the tube, or there is a bit of refrigerant, and there is an ice plug in it! Because the high pressure of the normal refrigerant heavy compressor is liquid, and the low pressure becomes gas after passing through the expansion valve! Therefore, if there is air inside, the pipe from the compressor to the internal unit will mix with gas and liquid, and a sound will be formed!

In addition, if there is a lot of refrigerant, the refrigerant cannot be completely changed from liquid to gaseous after the expansion valve, and then the pipe from the internal engine to the compressor will mix with gas and liquid to produce a sound! According to my analysis, it should be nothing more than these two cases! You can ask the repair master to deflate for you, and then measure the pressure of the refrigerant inside, if the pressure is too high, put some refrigerant off, and see if the situation can be improved!!

When the air conditioner is running or after the shutdown, due to the sudden change in temperature, it may lead to the thermal expansion and contraction of the plastic shell and the internal plastic parts, and therefore make a "click" sound, which is a normal situation, generally speaking, when the machine is just running, the temperature difference is too large, resulting in the phenomenon of thermal expansion and cold contraction, but when a certain expansion coefficient is reached, there will be no more clicker sound.

When the machine stops running, it will make a rattle sound due to the temperature difference, which is likely to happen to all air conditioners.

During the operation of the air conditioner, it will emit sounds similar to running water, gas (the sound of the reversing valve reversing instantaneously when the machine defrosts in winter), and boiling the pot (the sound of freon entering the indoor evaporator), which can be interpreted as the sound of refrigerant flowing in the machine and the sound of freon reflux in the machine.

Extended Materials. Causes and solutions to the loud noise of the indoor unit of the air conditioner.

1) Cause of failure: wall-mounted installation and fixing wall-mounted panels are not firm and loose or the wall surface is uneven.

Repair method: Re-fix the wall-hung panels, or treat the wall surface to keep the wall-mounted panels flat.

2) Cause of failure: The wall-mounted indoor fan motor is not in place to assemble the cross-flow wind wheel and fan bearing, resulting in a friction sound resulting in a loud sound of the indoor unit of the air conditioner.

Maintenance method: readjust the assembly position of indoor fan motor, cross-flow wind wheel and fan bearing.

3) Cause of failure: Poor assembly of indoor fan motor and cross-flow wind wheel.

Maintenance method: Separate inspection and judgment. First of all, remove the cross-flow wind wheel to eliminate noise. That is, to replace the cross-flow wind wheel (the reason is mostly that the cross-flow wind wheel is unbalanced or deformed); Otherwise, the internal fan motor is faulty, and the internal fan motor is replaced.

There are several root causes of the noise generated by the operation of the air conditioner and the noise generated by the pipes. The first is because the copper tubes are too close to the compression distance, secondly, the distance between the copper tubes and the sheet metal parts is too close, and finally it may be because the vibration of the compressor causes the copper tubes and copper tubes to collide with each other and produce noise. Air conditioner pipe ringing solution:

1. If the copper pipe is too close, which causes the compressor to vibrate the pipeline, you can try to add the pipe to the pipeline. 2. If it is the vibration of the compressor, which makes the pipe collide with the metal plate and produce noise, this is the reason why the distance between the copper pipe and the sheet metal parts is too close, which can be solved by increasing the damping rubber block. 3. The vibration of the compressor causes the noise of the copper pipe and the copper pipe to collide with each other, which can be improved by adding the insulation of the insulation pipe.

4. When the windshield is opened after the main engine is started, the noise of the indoor unit is normal. When the outdoor unit is started after 3 minutes, the noise of the indoor unit increases significantly. This phenomenon is caused by secondary throttling in the refrigeration system.

After the air conditioner is turned off, if it is found that the copper pipe of the evaporator of the indoor unit is crushed, it is necessary to check along the refrigerant pipe, replace the copper pipe at the problem point, re-vacuum it, and refill the fluorine, which can be solved.

Hello dear, glad to answer for you. The reasons for the sound of the air conditioning duct are as follows: 1. The internal air of the air conditioner will condense into small water droplets during the refrigeration process, and the sound of water flowing and dismantling inside the air conditioner.

This is normal and nothing to worry about. 2. The air conditioner is equipped with refrigerant, and the sound of the refrigerant flowing in the air conditioning pipe is a normal phenomenon. 3. The sound of the compressor, that is, the compression of the travel car to send a fault, should contact the maintenance personnel for maintenance and first grinding.

4. If the sound in the air conditioning pipe is loud and continuous, it may be that the pipe is deflated during installation, and it is necessary to ask maintenance personnel to repair or reinstall.

There are several reasons why there is a sound in the air conditioning pipes:

1.Pipeline vibration: The connecting pipes between the inside and outside of the air conditioner will vibrate during the operation of the air conditioner, and if these pipes are not fixed or unstable, it will cause noise in the pipeline.

2.Refrigerant leakage: If there is a leak in the air conditioning line, the refrigerant will spill out of the line, resulting in noise.

3.Abnormal noise of radiator fins: Abnormal noise will be emitted when the radiator fins between the inner and outer units of the air conditioner are aged, deformed, or damaged.

4.Incomplete cleaning: When dust or dirt appears inside the air conditioner, the air circulation is blocked, and noise is emitted.

To solve the problem of sound in the air pulse type adjustment tube, corresponding measures can be taken according to the different causes of the above problems:

1.Check whether the air conditioning lines are stable and repair or replace faulty parts.

3.Clean the air conditioning water circulation system and air circulation system, and replace the radiator fins in time.

4.Clean your air conditioner filter regularly to avoid the accumulation of dust and dirt.

If you are unable to resolve these issues on your own, it is recommended to contact a professional aircon repairer for inspection and maintenance to ensure that your aircon system can function properly.

1. There is a flowing sound in the air conditioning pipe, and the sound of the refrigerator flowing when the air conditioner defrosts and refrigeration is switched, if it is normal heating, there is no problem, if this problem often occurs, it may be that there is a problem with the air conditioner. 2. The sound of the air conditioning pipe may be the friction between the internal machine dispersed blade shaft and the rubber seat, the internal machine generally does not make a sound, the fault phenomenon of the air supply operation mode is the same, the noise is particularly obvious when the machine is shut down, and the side bearing is generated because the cross-flow blade is installed too far on the left side, and the distance between the blade and the bearing rubber seat is close to the sound when the touch occurs during operation. Suggested workaround:

1. If there is a problem with the air conditioner, then you can turn off the air conditioner first, and then restart it, if it is still useless, then you can only find someone to repair the air conditioner. 2. If the distance between the blade and the rubber seat is too close, you can move the distance between the two, so as to avoid the sound situation, but try not to move yourself when moving, or find professional personnel to move. 3. If the air noise is loud and continuous, which is unacceptable, you can adjust it yourself, if you can't solve it yourself, it is recommended to report to the air conditioning manufacturer for after-sales repair.

If the pipeline has"Sizzle"When installing, the pipe is deflated (especially the part out of the wall is easy to be deflated) will produce secondary evaporation, which will produce a very loud sound. If it is really an installation problem, replacing the external machine will not solve the problem.

Hello, there is a sound of water flowing in the pipe, this is a normal phenomenon, this is the sound of freon, don't mind too much, of course, you do think it's too big, you can let the after-sales help you take a look.

If you just bought it, it must be a quality problem. The old machine is normal,

It's a problem with installation, and it's estimated that the pipeline has a dead bend

I don't know, who do you ask me???

<> the air conditioning pipe is flowing in the refrigerant medium, and the sound is mostly due to the flow rate is too fast or there is air in the medium, which can be emptied by exhaust method. When the air conditioner compressor is not running, loosen the connecting nut connecting the thicker copper pipe to the outdoor unit of the air conditioner slightly. Then, plug in the power plug to turn on the refrigeration mode, and tighten it immediately after the compressor is started and the pressure comes out at the thick copper pipe joint of the outdoor unit.

Tips, this method is only suitable for air conditioners that do not use R410A refrigerant, and it is to rely on high-pressure freon to drive away the air in the pipeline, so we must pay attention to the fastest speed to complete the operation of tightening the nut to ensure that the loss of freon is reduced to a minimum. Air conditioners that currently use R410A's new refrigerant should not be used for this method. Be sure to use a dedicated vacuum pump.
