办公建筑大型变风量空调系统噪声计算及实测分析
Calculation and analysis on noise control of large-scale VAV system in an office building
摘要:
介绍了某超高层建筑采用的大型变风量空调系统配置,讨论了噪声控制的计算方法,分析了典型系统的送风路径与回风路径对室内声环境的影响,并结合竣工验收后的系统实测对噪声控制措施与计算方法进行了研究。理论计算及实测结果表明,设计工况下室内声学满足NC40①要求,可为其他类似项目的声学设计提供参考。

Abstract:
Presents the system configuration and operation strategy of large-scale VAV system in a super high-rise building. Discusses noise control consideration and calculation, and analyses the effect of supply and return air routes on indoor acoustic environment. Studies the control measures and calculations combined with acoustic site test after final acceptance of the project. Both theoretical calculation and site test show that the indoor acoustic environment can be controlled under NC40, which can be a reference for other similar projects.
