%X When there exist the branches whose ventilating volumes are supplied on demand in a ventilating network,the Scott-Hensley method cannot make reasonably adjustment to all branches contained in the circuits with fixed volume branches so that balance error of total ventilation pressure is concentrated wholly on these branches.Thus ventilating volume adjustment becomes very difficult.To solve this problem,a new optimization method based on improvement of the Scott-Hensley method is represented in which minimization of squared sum of algebraic sum of the ventilation pressure of all branches in a independent circuit about all independent circuits is taken as objective function,based on which balance error of circuits can be allocated into all or some of circuits on demand so as to realize all circuits adjustment and minimize balance error simultaneously.The method theoretically gives consideration of existence of branches with fixed volume in a ventilation network,and has no theoretical shortcomings for computer to solve.When solving,independent circuits are selected only one time and adjustment is made on all these circuits,correct results can be obtained.Because any ventilation system can be transformed into a system contained of fixed volume branches,the algorithm is actually no limits for application.
