本文概述了在通风网路中确定分支中风流方向的意义、目前进展情况以及现有的各种方法。本文作者通过具有代表性的通风网路,应用数学分析方法对现有的各种方法的实质、应用范围及其存在问题进行了研究,提出了确定角联分支中风流方向的新方法——井巷风阻比的复合判别法和线性方程的复合判别法。对分支中均有风流的任何复杂网路,建议采用通用法——线性方程法——确定角联分支中风流方向。最后,本文作者认为,在个别分支中无风流的任何复杂网路中如何一次性判别分支中风流方向尚需进一步研究。
This article provides an overview of the significance of the direction of airflow in branches to determine the branch flow, current status of progress, and various existing approaches. In this paper, the authors studied the essence, application scope and existing problems of various existing methods by means of the representative ventilation network and applied the mathematical analysis method, and proposed a new method to determine the direction of the airflow in the diagonal branch Composite discriminant method of lane wind resistance ratio and composite discriminant method of linear equation. For any complex network where there is wind in the branch, it is recommended to use the general method - the linear equation method - to determine the direction of the wind flow in the branch. Finally, the author of this paper thinks that it is necessary to study how to determine the direction of branch flow in one complex at any time in any complex network with no branch flow in individual branches.
