The noise of cooling tower is mainly dominated by fan noise and falling water noise. Fan noise is the noise generated by the fan when it is running, mainly aerodynamic noise, including rotation noise and eddy current noise. It also has reducer noise and motor noise that drives the fan. The falling water noise is the sound of falling water that collides with the tower chassis and the water accumulated in the tray when the cooling tower falls from the water spray device. Its value is related to the falling water height and the water flow per unit time. In addition to the noise mentioned above, there are noise from circulating water pumps, matched motors, and radiated noise from pipes.

Because the noise of the cooling tower affects the prediction mode and the size of the cooling tower, and the distance between the prediction point and the cooling tower, the delimitation of the range of different prediction modes is not clear at present. You can consult the manufacturer on the selection and range of the cooling tower mode.

的 The noise of the cooling tower affects work and life and brings inconvenience to people. There are four main ways to reduce the noise pollution of cooling towers: reasonable layout, reasonable selection of cooling towers, control of propagation channels, and protection of sound receiving bodies.
