Calculation and analysis on noise control of large-scale VAV system in an office building

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.
