Cooling tower noise control technology, cooling tower noise reduction scheme, reducing cold water tower noise

Cooling tower noise control technology and cooling tower noise reduction scheme, Shenzhen Quelte Sound and Noise Reduction Engineering Technology Co., Ltd. specializes in cooling tower noise control and cooling tower noise reduction . Cooling towers are usually installed on the roof, refrigeration equipment installed in the ground floor or basement, the noise of the building and the surroundings have had an impact, and because many more complex noise sources, noise control to bring a certain degree of difficulty. The management of such noise requires comprehensive consideration and comprehensive control of noise in a multi-system manner.

Noise control design requirements : The equivalent sound level radiated from the engine room to the outside world meets the noise limit of Category 6 in the “Code for Noise Control Design of Industrial Enterprises” GBJ87-1985, ie ≤60dB(A) at night; equivalent sound in the room The level meets the noise limit of Class 1 in the Acoustic Environmental Quality Standard GB3096-2008, that is, ≤55dB(A) between daytime and ≤45dB(A) at night.

Noise source analysis : Generally , the noise pollution problem has been considered in the design process. When designing and selecting equipment, some sound and noise elimination treatments have been considered. Such noise sources are mainly concentrated in chillers, chilled water circulation pumps, cooling water circulation pump cooling towers, and the like. Through the octave spectrum analysis of the above devices, the peak noise of these devices is mainly concentrated below 500HZ (inclusive), showing obvious low-frequency characteristics. Because the medium and low frequency noise has strong diffractive properties and long propagation distance, it will bring difficulty to the management.

Estimation of the main noise source Unit: dB ( A )

Serial number	Main sound source	Leq
1	High-efficiency variable frequency centrifugal chiller vibration	Have a noticeable vibration
2	Cooling water circulation pump	85.0
3	Chilled water circulation pump	87.5
4	Cooling Tower	75.0
5	High-efficiency variable frequency centrifugal chiller integrated noise	86

 

The noise control scheme is mainly designed from the following aspects:

First, the machine room is soundproof  

Second , the chiller and cooling water circulating water pump shock absorption

Third, the pipeline system shock absorption

Fourth , the cooling tower cooling fan sound insulation and cooling tower water disinfection

Design of the cooling tower noise management scheme according to the actual needs and requirements for conditions such as: installation location, the type of the sound source, the noise level and frequency of environmental / environmental requirements, ventilation requirements, noise reduction goals, targeted to the art design.
