毕托管与自动调节风阀相对位置的设计

摘要

对于总风量控制的变风量系统而言，变风量末端设备测得风量的偏差大小直接关系到整个系统风量控制的精确度。本文通过计算机仿真分析及试验分析，确定了变风量末端设备中的毕托管与自动调节阀的相对位置。%For vav system of total volume air control, the deviation size of air quantity measured by vav terminal equipment will directly affect the accuracy of the whole air volume control system. Through computer simulation analysis and test analysis, the relative position of Pitot tube and automatic adjustment of air valve in the vav terminal equipment is determined.
