伴随我国全民健身中心大量兴建,空调系统能耗巨大、运营成本过高的问题正逐步凸显,而适宜季节内合理利用自然通风可有效减轻空调系统的运行压力。针对方案设计阶段空间形态因子对自然通风性能的重要影响,本课题结合响应面方法,拟从自然通风系统建构、空间形态因子的敏感性分析、响应面模型建构及自然通风性能的多目标优化四个层面展开研究:通过调研归纳提取全民健身中心典型空间模式,利用形态学分析方法建构自然通风系统;结合局部和全局敏感性分析方法,探索空间形态因子对自然通风性能的作用机理,筛选关键参数;结合参数化建模技术、CFD数值模拟技术、试验设计和响应面方法构造高精度预测模型,代替流程复杂、计算耗时的流体仿真;利用多目标优化算法调用响应面模型展开快速优化,并开发操作友好、方便易用的人机交互界面。课题提出基于响应面的自然通风性能优化方法,有效支持方案阶段设计决策,有助于全民健身中心在生命周期内的低成本可持续运营。
英文摘要
With the construction of a large number of National Fitness Centers in China, the problems of huge energy consumption and high operating costs of air conditioning systems are gradually becoming more prominent. The proper use of natural ventilation during appropriate season can effectively reduce the operating pressure of air conditioning systems. In view of the important influence of spatial morphological factors on the natural ventilation performance during the design stage, the research combines the response surface method and intends to conduct research from four levels: construction of natural ventilation system, sensitivity analysis of spatial morphological factors, construction of response surface model and multi-objective optimization of natural ventilation performance. Through investigation, the typical spatial patterns of the National Fitness Center are extracted, and the natural ventilation system is constructed using morphological analysis methods. Based on local and global sensitivity analysis methods, the mechanism of spatial morphological parameters on natural ventilation performance is explored and key morphological parameters are selected. Combining parametric modeling technology, CFD numerical simulation technology, experimental design and response surface method, a high-precision prediction model is constructed to replace fluid simulation with complex process and time-consuming calculation. Finally, the multi-objective optimization algorithm is used to call the response surface model to carry out rapid optimization, and a friendly, easy-to-use human-computer interaction interface is developed. The subject proposes a method of optimizing natural ventilation performance based on response surfaces, which could effectively support the design decisions of the spatial morphology at the design stage, and help the low-cost sustainable operation of the National Fitness Center during the life cycle.
