被动式建筑外窗节能技术的研究现状

Research status of passive building external window energy saving technology

从被动式建筑外窗的传热系数计算公式出发,分别从外窗的玻璃、外窗的窗框、外窗的暖边间隔条、外窗的安装方式等方面总结分析了现在国内外的外窗研究现状。通过对比分析,得出适用于现行被动式建筑外窗的结论。研究旨在为被动式房屋外窗选择上提供具有实际意义的想法,提高被动式建筑的节能效率。

Based on the calculation formula of heat transfer coefficient of passive building exterior windows,this paper summarizes and analyzes the current research status of exterior windows at home and abroad from the aspects of the glass of exterior windows,the window frame of exterior windows,the warm edge spacer of exterior windows and the installation mode of exterior windows,and makes a comparative analysis,and draws a conclusion that is suitable for the current passive building exterior windows.The purpose of this paper is to provide practical ideas for the selection of passive building windows and improve the energy efficiency of passive buildings.
