针对当通风网络存在按需供风的分支时,Scott-Hensley方法无法对存在具有此特点的分支的回路的风量进行有效调节,回路风压归零误差全部集中在那些按需供风分支上,这给风量调节带来一定困难,提出了一种新的通风网络解算方法.该方法通过使所有独立回路分支风压代数和的平方和最小化的方法,将回路风压归零误差按需分散到所有回路或某些回路上,从而实现所有回路的调节,同时使不平衡误差最小化.该方法理论上考虑到了通风网络中存在按需供风分支的情况,用计算机进行求解不存在理论上的缺陷.风网解算时,只需选一次独立回路且同时对所有独立回路进行风量调节,即可获得正确的结果.由于任何通风网络均可转换成含按需供风分支的网络,因此该方法事实上不存在局限性.
In the case of the on-demand air-supply branch in the ventilation network, the Scott-Hensley method can not effectively regulate the air flow of the loop in the branch with this characteristic. The return air pressure zero-error is mainly concentrated on those on- This brings a certain difficulty to the air volume adjustment and proposes a new method to solve the ventilation network.This method minimizes the sum of the square sums of the sum of the air pressure algebraic sum of all the independent loop branches, Distributed to all the loops or some loops, so as to realize the adjustment of all the loops, at the same time minimize the unbalance error.This method theoretically takes into account the fact that the demand-for-supply branch exists in the ventilation network and the computer does not exist to solve the theory On the wind network solution, just select a separate circuit and at the same time for all independent loop air volume adjustment, you can get the correct result.Because any ventilation network can be converted into a network with on-demand wind branch, There is virtually no limitation to this method.
