双层塑料窗传热系数的研究

Double Plastic Window Heat Transfer Coefficient of Research

依据外窗保温性能检测方法,将2种不同配置的塑料窗复合到一起构成双层塑料窗进行传热系数的研究,通过调整双层窗间距、参考窗的热室侧表面温度最终将外窗的传热系数K值做到1.0W/(m2·K),可以应用于超低能耗建筑,并与目前达到同等保温性能的节能窗进行成本造价分析。

According to outside window insulation detection methods, the two kinds of different configuration of plastic composite together constitute a doublelayer plastic window heat transfer coefficient of the study, by adjusting the distance between double window,refer to the hot chamber side of the window surface temperature will eventually outside the window heat transfer coefficient K value do 1.0 W/（m^2·K）,can be used in the ultra low energy consumption building,and has reached with the same heat preservation performance of energy-saving window cost analysis.
