摘要
模拟研究含半透明相变材料层玻璃屋顶的动态传热特性,分析相变材料半透明特性和天顶角对含相变材料层玻璃屋顶动态传热特性的影响。结果表明,相变材料半透明特性和天顶角对玻璃屋顶的温度延迟、内表面温度、热流、透射太阳能等影响显著;双层玻璃厚度为18mm,相变材料层厚度为20mm的玻璃屋顶结构适合中国北方严寒地区。
The simulation study of dynamic heat transfer characteristics of glass roof containing translucent phase change material layers is conducted to analyze the effect of translucency performance of phase change materials and zenith angle on the dynamic heat transfer characteristics of glass roof with phase change material layers.The results show that the effect of translucency performance of phase change materials and zenith angle on temperature delay,internal surface temperature,heat flow and transmitted solar energy is significant;the glass roof structure with 18 mm thickness of double glass and 20 mm thickness of phase change material layer is suitable for the severe cold regions in northern China.
