通风网路的动坐标解法,是作者新提出的一个方法,其基本原理,是把通风网路的一部分特性曲线画在定坐标纸上,其余曲线全部画在透明的动坐标纸上,虽后把动坐标放在定坐标上,使定、动两类坐标曲线相交,并按一定的规律移动动坐标,最后,当各交点所对应的风量、风压符合风量与风压两平衡定律时,图示风量即为所求风量. 本方法的优点是:1)设备简单,解算迅速;2)对于某些用现用图解法或数学解析法所不能解算或不易解算的通风问题,它可以解算;3)用这种方法来研究风量调节问题,研究个别风机的调换,以及研究网路个别风阻的改变对整个通风的影响也很方便.因此,本方法的提出,有一定的理论与实用价值,可供现场与有关人员参考.本方法也同样适用于解非线性复杂电路.
Ventilation network moving coordinate solution is a new method proposed by the author. The basic principle is to draw a part of the characteristic curves of the ventilation network on the fixed coordinate paper, and all the remaining curves are drawn on the transparent movable coordinate paper. The moving coordinates on the fixed coordinates, so that the fixed and dynamic two types of coordinate curves intersect, and move according to a certain law moving coordinates, and finally, when the intersection of the corresponding air volume, air pressure in line with wind and wind pressure balance of the two laws, Figure shows the amount of wind is the amount of wind requested. The advantages of this method are: 1) the device is simple, rapid solution; 2) for some of the current graphical method or mathematical analysis can not solve or not easy to calculate the ventilation problem, It can be solved; 3) It is also very convenient to study the regulation of the air volume by this method, to study the exchange of individual fans and to study the influence of the change of individual air resistance of the network on the entire ventilation. Therefore, Theoretical and practical value, for reference with the field and the relevant personnel.This method is also suitable for solving nonlinear complex circuits.
