摘　　要：在解析现有自然通风性能优化方法特征的基础上,提出适用于方案阶段基于响应面的自然通风优化流程,核心环节依次为:参数敏感性分析、试验设计、响应面模型建构、多目标优化,并采用ANSYS Workbench搭建协同优化平台。以全民健身中心典型空间模型为例展开实践探讨,提取11个几何形态参数作为输入变量,选取空气龄、温度和风速作为优化目标。应用参数化建模技术、流体动力学计算数值模拟技术获得200组数据,采用Kriging算法构建响应面模型;利用遗传算法调用响应面模型数据进行快速寻优,最终获得优化候选方案,以及各几何参数的优化区间。Based on the analysis of the characteristics of existing natural ventilation performance optimization methods,the optimization process based on response surface suitable for design stage was proposed. The core steps were: parameter sensitivity analysis,experimental design,response surface model construction,multi-objective optimization,and collaborative optimization platform was established by using ANSYS Workbench. Taking the typical space model of the National Fitness Center as an example,11 geometric parameters were explored as input variables,and the air age,temperature and wind speed were selected as the optimization targets. By using the parametric modeling technology and CFD numerical simulation technology,200 sets of data were obtained,and the response surface model was constructed by Kriging algorithm. The genetic algorithm was used to call the response surface model data for fast optimization,and finally the optimization candidates and the optimization interval of each geometric parameter were obtained.
