【英文篇名】 Statistical model of energy consumption by air conditioning buildings 【作者中文名】 武建勋; 【作者英文名】 Wu Jianxun; 【作者单位】 同济大学热能系; 【文献出处】 暖通空调, HV 能耗; 空调; 主元分析法; 【英文关键词】 statistical model; energy consumption; air conditioning; principal component analysis; 【摘要】 阐明了空调建筑能耗模型的三大特点:建筑整体性、过程动态性和因素综合性,分析了影响空调建筑能耗模型的诸多变量与影响因素,并在工程实践、现场实测以及研究模拟的基础上,提出了简单实用的空调建筑能耗模型的框架实例,用主元分析法判定了模型影响因素的主次关系。 【英文摘要】 States that three points must be considered in the modelling, i. e. the building in its entirety, dynamics of the process of interest, and the interaction and synersism between the influencing factors. Frames a functional model based on a great deal of ensineering practice, field measurement, analysis and modelling. Ranges the influencing factors, with the principal component analysis, in order of their contribution to the model.
