摘要
商业综合体周边通常紧邻住宅及高档办公建筑,综合体附属的室外建筑服务设备所产生的噪声污染问题越来越普遍。本文针对某商业综合体屋面设备噪声影响周边办公楼的问题进行隔声降噪改造,提出排油烟风机和冷却塔的隔声、消声方案。改造后办公楼区域背景噪声均达到国家规范标准,室内声环境良好,原有的噪声问题得到解决。该项目噪声治理结果表明:排油烟风机采用隔声罩进行隔声降噪有明显的效果;冷却塔顶部风扇对高层建筑产生影响时,可考虑采用消声导流筒。本工程实践为排油烟风机和冷却塔等屋面设备的隔声降噪提供了一种可靠适用的方案。
The surrounding areas of commercial complexes are often in close proximity to residential and upscale office buildings,leading to an increasing prevalence of noise pollution from outdoor service equipment affiliated with these complexes.This article focuses on the issue of noise pollution caused by rooftop equipment in a specific commercial complex,which affects neighboring office buildings.It proposes sound insulation and noise reduction solutions for the exhaust fans and cooling towers.After the renovation,the background noise in the office building area meets national regulatory standards,ensuring a good indoor sound environment and effectively resolving the existing noise issues.The noise control results of this project indicate that using acoustic enclosure for exhaust fans significantly reduces noise.When the top fans of the cooling towers affect high-rise buildings,considering the use of muffler air duct may be a viable option.This engineering practice offers a reliable and applicable solution for sound insulation and noise reduction of rooftop equipment such as exhaust fans and cooling towers.
