There are two ways to generate noise when the evaporative air cooler is running. One is from the equipment itself and it does not meet the national standard requirements. The other reason of the loudly noise generated is that the air supply duct did not do well. So how to distinguish and solve it?

1. The noise of the air supply pipe project is large, which is called the abnormal sound of the air duct in the industry. If There is a strong wind blowing sound in the air supply pipe. It should due to The thickness of the galvanized sheet material is not enough, or it may be that the distance between the flanges is too far and the ribs have not been treated. Of course, there are different solutions for different problems. If there is a “crack” noise, it is mostly galvanized iron is too thin, the distance between the flanges is too far and there is no reinforcement rib. If it is a “whooping” sound, it is mostly caused by a large air volume, or the air duct is too small. If you want not to change the current air supply system, there is only one solution, that is to adjust the wind speed, and make corresponding noise data adjustments according to the site conditions.

2. The air cooler itself is very noisy. Generally, this situation must be caused by the fact that you bought poor quality air cooler and the supplier did not give professional scheme . If this situation has already occurred, the first solution is to change the air cooler machine, but it is big project. Then there is another solution that is to install a professional frequency conversion adjustment system for your air cooler. It is realized by operating parameters, so the frequency conversion adjustment system is used to improve the noise of the air cooler and at the same time reduce the air supply volume. The impact for the overall cooling project is a little obvious. While it is little for position cooling project.

But no matter which solution is adopted to solve the problem of high operating noise, there will be certain disadvantages. Therefore, when we have high noise requirements, we must communicate with the supplier before purchase. Otherwise, when the installation of the project is completed, The cost and time of rectification will be much more.
