浅淡被动式门窗中空玻璃U值

Analysis on the U Value of Passive Door and Window Insulating Glass

简要介绍了国内外被动式建筑节能标准要求,并对中空玻璃传热系数U值几个容易混淆的相关概念加以理解,同时给出传热系数测试方法、测试标准及其运用计算软件的点评,通过运用中空玻璃稳定状态下传热系数U值的计算公式及取值,计算出各种配置中空玻璃的U值,重点论述中空玻璃配置、中空腔气体组成、气体层厚度和玻璃厚度对中空玻璃稳态U值的影响,并分别给出了满足欧洲标准和河北标准对被动式门窗用中空玻璃U_g值的要求的各种配置下的中空玻璃气体层厚度和玻璃厚度范围和较为经济的范围。

This paper briefly introduces the requirements of domestic and foreign passive building energy efficiency standards, and make a clear understanding of some easily confused concepts of the insulating glass heat transfer coefficient U value, at the same time, listing test method of heat transfer coefficient, test standard, calculated various insulating glass U value, mainly discussed the influence of the steady insulating glass U value by insulating glass configuration, gas composition, gas layer and thickness through computer software＇ reviews, and separately satisfied the U_g requirements of passive insulating glass under various glass layers, gas thickness and ranging thickness of glass in a economic way under EU Standard and Hebei Criteria.
