摘　　要：利用建筑中的次要空间腔体对主要空间形成热缓冲效应,是一种既经济又有效的微气候调节和节能基础手段,在我国值得推广。笔者通过对南京冬夏气候条件下建筑缓冲腔体的DeST温度模拟,验证了缓冲腔体在相应季节的缓冲效果。在水平层级上,中心区是理想的夏季预冷腔体,其次是北面腔体;南区是最好的冬季预热腔体,其次是中心区。在垂直层级上,除地下室兼顾预热预冷功能外,顶层是较佳的冬季预热腔体,底层有些许夏季预冷作用。最后,总结了腔体缓冲的原型模式。The chamber of auxiliary space can work as thermal buffer of main space in buildings.It is an economical and effective basic-way for adjusting micro-climate and saving energy,which is worth to be widely applied domestically.With the aid of DeST,the temperature performance of architectural buffering chambers in Nanjing climate condition was simulated,proving its effectiveness in relevant seasons.In horizontal level,mid zone is the best summer precooling chamber and north zone ranks the second,and south zone is the best winter preheating chamber,followed by mid zone.In vertical level,underground room has both precooling and preheating function.Besides that,top floor is a good winter preheating chamber and ground floor has a little summer precooling effect.In the end,the prototype mode of chamber buffering was summarized.
