低温送风诱导式缩放风管具有结构简单、造价低廉、节省能耗、噪声低、维修工作量小和能利用普通风口等优点，但不易达到较高的诱导比。运用CFD软件对风管内部流体特性进行模拟，通过云图进行压力分析，并在云图静压较低处对应地设置二次风口。计算各种情况下诱导风管的诱导比，通过诱导比计算值的对比，确定出二次风口的最佳位置，设计出诱导式缩放风管的吸收段。
低溫送風誘導式縮放風管具有結構簡單、造價低廉、節省能耗、譟聲低、維脩工作量小和能利用普通風口等優點，但不易達到較高的誘導比。運用CFD軟件對風管內部流體特性進行模擬，通過雲圖進行壓力分析，併在雲圖靜壓較低處對應地設置二次風口。計算各種情況下誘導風管的誘導比，通過誘導比計算值的對比，確定齣二次風口的最佳位置，設計齣誘導式縮放風管的吸收段。

Considering its simple structure , low cost, energy savings , little noise, small amount of maintenance and adaptability to normal vent , cold air distribution induction scaling duct is spoken highly of .But it is not easy to reach a high induction ratio .In this paper , CFD software was adopted to simulate internal fluid properties in the in-duction ducts .Then secondary air inlets were located in the position with the lowest static pressure after the analy -sis of the contours .Finally, the induction ratios for different ducts were calculated .After comparing induction rati-os, the optimal location of secondary air inlet is determined and the absorption section is designed .
