Application of ultra-quiet cooling tower technology in Shenzhen Modern Performing Arts Center
Author：Trlon Views: Time:2020-10-14
Shenzhen Modern Performing Arts Center is located at 5001 Hongli West Road, Futian District, Shenzhen. It is a multi-functional cultural entertainment and leisure venue owned by the Municipal Federation of Trade Unions. It has a 14-meter super wide screen, a standard performance stage, international advanced digital six-channel surround sound and video projection equipment. Not only can the audience enjoy the unique audiovisual effects of movies in this province, but also provide high-quality rental services for the majority of enterprises and institutions.UTMCooling tower noise reduction treatment manufacturerUTMCooling tower noise reduction treatment manufacturer
But while bringing joy to people, the cooling tower equipment of its central air-conditioning system has caused trouble to nearby residents and seriously affected the normal life of residents (the cooling tower is only 6 meters away from the residential building). How to achieve such a close distance without disturbing the residents? However, it has always been a thorny issue that does not affect the heat dissipation of the existing mainframe. The construction unit and the design proposed a plan: not restrict the brand, online public bidding, and do not accept enclosure noise reduction as the premise, requiring the cooling tower to achieve a linear distance of 6 meters in the daytime.

With such a challenging technical problem, the cooling tower solution with noise reduction technology recommended by trlon cooling tower has become a highlight of this bid. The editor will take you to understand the ins and outs of the rectification project.
The original cooling tower is tightly wrapped with a noise barrier, without ventilation, and it is still low-frequency nuisance. In the picture above, it can be seen that the cooling tower is close to the residents' windows, and the straight line distance is strictly 6 meters.
In order to reduce the fan noise of the cooling tower body as much as possible, the coaxial multilayer fan blade ultra-quiet fan (21 pieces) is adopted, and the aluminum alloy blades with passivation treatment have the characteristics of chemical corrosion resistance. The principle of the fan is to reduce the speed (120 rpm) to increase the air volume. Compared with the ordinary fan, it can achieve the effect of noise reduction close to 20dB (A), which creates a new standard for meeting more stringent noise reduction conditions.
When cooling tower production or noise control, fully consider the causes and characteristics of cooling tower noise, and prescribe the right medicine. Under the premise of ensuring the technical parameters required by the equipment, the equipment is optimized and upgraded, and the noise source is suppressed and rectified in a targeted manner. Its biggest advantage is that it will not affect the heat dissipation effect of the cooling tower and increase the floor load. The noise of different frequencies can be effectively suppressed, the appearance is beautiful, and the use space of the urban environment is expanded.
The technical highlight of this noise reduction technology is that it does not pass enclosures, does not reduce the air volume in and out (the air volume is measurable), does not affect the heat dissipation efficiency, does not increase the floor load, and achieves noise reduction. It is a way to subvert the traditional noise reduction. This technology has been used in landmarks such as Guangzhou Metro, Hongrongyuan One City Center, Beijing Vanke, Xi'an Greenland Center, Changsha Zhonghai Universal City, Wuhan Poly Times, Hilton Hotel, Luohu Branch of Traditional Chinese Medicine Hospital, etc. The project is widely used. Welcome to experience the quietness and efficiency brought by the cooling tower.UTMCooling tower noise reduction treatment manufacturer

The bidding requires that after the installation of the new cooling tower is completed, the acceptance condition is a noise inspection report issued by a third-party qualified unit. The value of the report needs to meet the requirements of 6 meters to achieve 60 decibels during the day and 50 decibels at night. In the end, the cooling tower with its own noise reduction technology provided by trlon passed the acceptance at one time!
