变风量系统送风散流器设计选型要点

Outlines of supply air diffuser design and selection of VAV systems

变风量空调系统运行时,通过散流器的送风量总是在最大送风量与最小送风量之间变化。如送风散流器设计选型不合理,空调区域内会出现空气温度分布不均匀、ADPI低于80%、舒适性下降的现象。分析了变风量系统气流分布可能出现的几种不利情况,给出了变风量系统设计时选择送风散流器的设计要点与选型方法。

The supply air volume of diffusers are always variant between maximum volume and minimum volume when a VAV system is operating. If a diffuser is not selected properly, it will lead to non-uniformity of room temperature, ADPI less than 80 percent and comfort sensation decreasing in air conditioned zones. Analyses the air distribution of VAV systems in some unfavorable conditions. Gives some design points and selecting methods for supply air diffusers of VAV systems.
