剧院空调大尺度静压箱风量平衡及优化设计研究

Study and design of air balance of large-scale static pressure box air conditioner in theaters

以剧院等大空间建筑较常采用的座椅下送风系统的风量平衡为目标,对具有复杂内部结构的大尺度静压箱进行研究,在对风平衡调节措施进行分析的基础上,采用计算流体动力学(Computational Fluid Dynamics,CFD)方法对静压箱内的空气流动进行模拟,利用风口调节方式实现了系统的风量平衡,并进一步通过对静压箱内部结构及送风参数的调整,实现了内部压力分布的均衡,提出了大尺度静压箱的风量平衡措施及优化设计方法.

As the goal of air balance of static pressure box in the under-seat air supply system used in theaters and other large buildings, this paper studies of complex internal structure of the large-scale static pressure box, using CFD （Computational Fluid Dynamics） to simulate the air flow in the static pressure box, outlet adjustment to achieve a balance of air volume system for further adjustment of the internal structure and parameter of the static pressure box. The balance of internal pressure distribution is realized and a method for air balance of large-scale static pressure box air conditioner used in theaters and optimal design are provided.
