The function of cooling tower noise processing is to eliminate fan noise, motor noise, reducer noise, water spray noise and noise radiated by other accessories and equipment when the cooling tower is running. The trlon air conditioner analyzes the overall noise of the cooling tower. The noise of the fan, the motor and the water splashing noise are relatively large, and the noise of the fan exhaust is 5-10 decibels higher than the intake noise. The frequency spectrum shows that the fan noise is a continuous low-frequency oscillation, and the noise generated by the falling water hitting the water pan will be concentrated on the high-frequency scale. In summary, the overall noise of the cooling tower is mainly low-frequency noise, with a noise value of 55-85 decibels.

Cooling tower noise management method
1. The high-efficiency equipment for reducing the noise of the cooling tower fan is a muffler. The main point of Hanks's sound insulation and noise reduction is to calculate the noise frequency spectrum of the fan and plan the muffler equipment that fits the on-site environment to achieve the purpose of high-efficiency noise reduction.
2. Regarding the vibration noise of cooling tower equipment, you can choose to install vibration damping equipment with appropriate frequency and load-bearing structure at the bottom of the equipment.
3. To reduce the overall noise of the cooling tower, the Hanks sound insulation plan has a sound-absorbing and sound-proof barrier combined with a sound-absorbing louver at the bottom to achieve the triple effect of noise reduction, corrosion resistance and heat insulation. The sound insulation barrier for large-scale cooling tower equipment planning Another plan for strong wind pressure resistance.
The role of cooling tower noise management
To reduce the environmental noise around the cooling tower equipment, the project can refer to the national environmental protection category 1 area social and living environment noise emission limit of 45 decibels at night.
