严寒地区超低能耗建筑用窗安装节点优化的研究探讨

RESEARCH ON THE OPTIMIZATION OF INSTALLATION JOINTS FOR SUPER-LOW ENERGY WINDOWS IN COLD REGIONS

文中以我国北方严寒地区城市哈尔滨为例,基于超低能耗建筑综合体示范项目的实际情况,采用市场上普遍应用的塑料窗和铝木复合型窗,对它进行内部型材改造。且考虑不同的安装做法,利用WINDOW和THERM软件进行模拟计算,对比窗框系统在安装节点处的温度和安装节点处的线性传热系数值,横纵向定量分析,找到超低能耗窗在严寒地区安装中的优化方案,进而提出改善设计,研究对超低能耗建筑用窗在严寒地区的应用推广具有积极意义。

This paper takes Harbin,a city in northern China known for its harsh winters,as a case study.Based on the actual conditions of a super-low energy consumption building demonstration project,it explores the internal pro-file modifications of commonly used plastic and aluminum-wood composite windows.By considering different instal-lation methods and utilizing WINDOW and THERM software for simulation calculations,the study compares the temperature and linear thermal transmittance coefficients at the installation joints of the window frame systems.Through quantitative analysis in both horizontal and vertical directions,the research aims to identify optimization strategies for installing super-low energy windows in cold regions.The findings propose design improvements,which are significant for promoting the application of energy-efficient windows in extremely cold climates.
