Causes and solutions of air conditioning noise

After the noise appears, it is generally very simple for maintenance personnel to bring instruments, and only one average value can be measured, that is, normal wind. Generally speaking, there will be no problem, and many of the noises mentioned are abnormal noises, which are usually very high in decibel at a certain frequency and need special instruments in the laboratory to detect them.

Sports problem

What is easy to go wrong is that the electrical components of the internal machine, mostly motors, will produce some electromagnetic noise, which sounds uncomfortable and squeaky.

* * * Vibration problem

If some parts of the internal machine do not cooperate well, it may produce * * * vibration.

Refrigerant flow problem

It may be the noise caused by the flow of refrigerant in the pipeline. Because the indoor unit may intercept, that is, control the flow rate of refrigerant, so that noise may be generated when the flow rate is fast.

solution

In view of the above problems, it is necessary to measure the frequency and decibel height of abnormal sound under special instruments in the laboratory, and then repair or replace parts according to the specific situation.
