摘要
不同的窗型设计其外窗构造不同,外窗的传热系数差异较大。通过对典型窗型的设计和理论计算,结合实验室实测数据,分析玻璃传热系数、型材传热系数、线传热系数对外窗保温性能的贡献率,提出窗型设计要点,合理降低外窗传热系数,满足不同气候区对外窗保温性能的需求。
The heat transfer coefficient of the outer window varies greatly with the different window design and the structure of the outer window.In this paper,through the design and theoretical calculation of typical window type,combined with the measured data in the laboratory,the contribution rate of glass heat transfer coefficient,profile heat transfer coefficient and line heat transfer coefficient to external window insulation performance is analyzed,and the key points of window type design are proposed to reasonably reduce the external window heat transfer coefficient and meet the requirements of external window insulation performance in different climate areas.
