The noise of water chiller is a kind of noise pollution. Too much noise makes people tired, and causes irritability, which seriously affects people's working conditions! 

So how to solve the noise of water chiller? We provide you with the following solutions!

1、 Causes of noise in water chillers

1. When the blade rotates, it will rub or impact with the air.

2. Because of the vortex generated by the blade, it will also produce noise.

3. The air duct resonates with the shell to produce noise.

4. The abnormal noise will be caused by insufficient accuracy, improper assembly or poor maintenance of bearings.

5. The motor also makes noise.

2、 Noise solution of water chiller

1. It is suggested that if the axial-flow fan has the configuration of moving wing and stationary wing, the number of blades of the two is not equal, so as to avoid greater noise resonance.

2. The installation angle of the blade shall not be too large, and the blade bending shall be smooth, and the sudden change shall not be too large.

3. The joint between the air duct and the inner surface of the fan shell shall be smooth to avoid rough and uneven, which may cause tearing sound. In addition, in the design, sometimes the air duct can be covered with anti sound material to reduce noise.

4. In the selection of equipment, the selection of regular products should be strictly carried out, and the humanized design of equipment should be considered.
