当前对通风网络的解算方法主要是采用渐近计算法,可以徒手计算,也可以编制程序输入电子计算机进行计算。但其实质都是对多元二次方程组的求解问题。对于比较复杂的通风网络,进行风量自然分配计算的工作量是相当繁重的,所以有必要研究简化计算方法,达到比较简便地解算某些通风计算问题之目的。近些年来,国内外都进行某些网络变换方法的研究,如星形和三角形网络的等效变换以及多极等参量变换等。本文以文献〔3〕、〔4〕为基础,并在一些方面加以发挥,试图以等参量变换法解算某些通风计算问题。
At present, the method of solving the ventilation network mainly adopts the asymptotic calculation method, which can be calculated by hand or by inputting a computer program into the calculation. But its essence is to solve the multivariate quadratic equations. For more complex ventilation networks, the workload of natural distribution calculation of wind volume is quite heavy, so it is necessary to study the simplified calculation method and achieve the purpose of solving some ventilation calculation problems relatively easily. In recent years, some methods of network transformation have been studied both at home and abroad, such as equivalent transformation of star and triangle networks and parametric transformation of multipole. Based on the literature [3] and [4], this paper gives some examples and tries to solve the problem of some ventilation calculation by the equivalent parameter transformation method.
