阳光板的光学和热学性质的实验和理论研究

EXPERIMENTAL AND THEORETICAL STUDY ON THE OPTICAL AND THERMAL CHARACTERISTICS OF SUNLIGHT PANEL

测试了一种双层阳光板的光学总透射比和热损系数 ,并与窗玻璃的实验值进行对比。结果表明 ,阳光板槽道东西走向与南北走向相比 ,其光学透射比较大 ,热损系数几乎相等。同时对其进行了理论计算。

This paper presents an approximate calculation method on the transmissivities and heat loss coefficients of polycarbonate panel and window glass,and compares them with the experimental data.The results show that the transmitivity of west east channel panel is larger than that of north south channel panel,and their heat loss coefficients are approximately equal and nearly one half of that of window glass.
