针对现代航站楼大面积玻璃幕墙具有建筑能耗高的缺陷，借助水的高显热蓄热优势，构建了航站楼水幕墙构造的节能构造模型，该构造模型将水介质良好的蓄热性与建筑围护结构有机结合，使其在机场航站楼等大型高能耗建筑中具有良好的开发前景。根据航站楼等高窗墙比建筑的传热能耗特点，重点从建筑节能的角度探讨了这类建筑的构造改进途径，通过分析夏季水幕墙结构在太阳辐射和对流换热双重作用下的热交换规律，初步得出了水幕墙结构的节能效果。以南京禄口机场T2航站楼南立面玻璃幕墙为例，分析了利用所构建模型对该建筑节能的改进效果，为类似高窗墙比大型公共建筑的节能改进提出了可行途径。

With the high sensible heat storage advantage of water, an energy-saving structure model called water curtain wall structure is built for the large area glass curtain wall in modern terminal with de-fects of high energy consumption. The structure model combines the thermal storage superiority of water and the building structure, which has good development prospects in the airport terminal and other large energy architecture. According to the heat transfer characteristics of terminal such as large window-wall ratio building, focus on improving ways of building construction from building energy efficiency, and obtain energy saving effect of the structure initially through the analysis of heat exchange law under the effect of solar radiation and convection heat transfer for water curtain wall structure in the summer. The glass cur-tain wall for the Nanjing Lukou International Airport T2 terminal south fa ade as example, the building en-ergy efficiency is analyzed by the proposed model. Meanwhile, the feasible improving methods of building energy efficiency are proposed for public building with large window-wall ratio.
