存在固定风量分支的通风网络解算新方法

A New Optimization Algorithm for Ventilation Network With Fixed Volume Branches

当通风网络存在固定风量分支时 ,Scott-Hinsley风网解算方法将风压归零误差全部集中在固定风量分支上 ,从而增加了风量调节的难度。通过修正Scott-Hinsley方法的缺陷 ,提出了一种新的全回路调节方法 ,该方法理论上考虑到了通风网络中存在固定风量分支的情况 。

When there exist the fixed volume branches in a ventilation network, the Scott-Hinsley method will concentrate the balance error of total ventilation presure in a circuit on the branches with fixed volume, thus increasing the difficulty in air volume adjustment. A new method for all circuit adjustment is proposed based on the improvement of scott-hinsley method. It considers theoretically the existence of fixed volume branches in a ventilation network and can realize an adjustment of all imdependent circuits and an on-demand allconcation of the balance error.
