【摘要】：利用通风系统回路阻力平衡定律,提出了通风系统存在自然风压时各分支的风量对自然风压产生某种反应的模型,从风量和风压角度给出了计算这种反应强度的方法;根据需要保留自然风压对通风系统所带来的正面作用,抑制其所带来的负面作用,基于尽可能使参与调节的分支数量最少化以及其风阻增、减值最小化的原则提出了优选分支调阻调节法,并建立了相关最优调节模型。为了快速求解该模型,结合回路阻力平衡定律和通风系统按需分风要求,通过对优化模型约束条件的线性化处理以及对按需分风要求的特别处理,简化了最优调节模型。研究结果表明:该模型可以计算自然风压作用下通风系统各分支的风流分布情况,相应的调控策略;可以确定调节设施的安装位置、数量及相关参数。
[Abstract]:The use of loop resistance balance law of ventilation system, puts forward the existing natural wind pressure ventilation system of the branch of the air have a reaction to the natural wind pressure model, a method is given for calculating the reaction intensity from the air volume and pressure angle; according to the positive effect of preservation of natural wind pressure on the ventilation system caused by the inhibition of the negative effect brought the number of branches, as far as possible to participate in the regulation of the minimum and the drag increase based on the principle of minimizing the impairment of preferred branch trimming adjustment method, and establish a optimal regulation model. In order to solve the model, the loop resistance balance law and the required air ventilation system, through the linearization of the constraint conditions of the optimization model and according to the special treatment for air requirements, simplify the optimal regulation model. The results show that the model can calculate the natural The wind flow distribution of each branch of the ventilation system and the corresponding control strategy under the action of wind pressure, the installation position, quantity and related parameters of the regulation facilities can be determined.
