摘要
开展了含石蜡玻璃屋顶大庆地区动态传热实验,研究了熔点、石蜡厚度对玻璃屋顶传热的影响情况。实验结果表明:石蜡材料熔点对含石蜡玻璃屋顶室内温度和延迟时间均有较大影响,且熔点越高,效果越明显;石蜡材料厚度对含石蜡玻璃屋顶室内温度有一定影响,对延迟时间影响不大,且不考虑光学特性时,厚度越大,蓄热效果越好。
The dynamic heat transfer experiment with paraffin-filled glass roof was carried out in Daqing city. The influences of melting point and filling thickness on the heat transfer of paraffin-filled glass roof were studied. The results show that the melting point of paraffin has a great influence on the temperature and delay time of paraffin-filled glass roof. The higher the melting point, the more obvious the effect. The thickness of paraffin has a certain influence on the temperature of paraffin-filled glass roof, has little influence on the delay time. The greater the thickness, the better the thermal storage effect without considering the effect of optical performance.
