透过玻璃窗的太阳散射辐射得热量测试与模拟研究

RESEARCH ON MEASUREMENT AND SIMULATIONG FOR DIFFUSE SOLAR HEAT GAIN THROUGH GLASS WINDOWS

通过搭建室外太阳散射辐射得热量的测量装置,对室内太阳散射辐射得热量进行了试验研究,并通过建立理论模型对测试结果进行了验证分析。结果表明:室内太阳散射辐射得热量和室外太阳散射辐射强度随时间规律变化,两者变化趋势一致。多组实验数据验证得出该实验装置对太阳散射辐射得热量的测试是可行的。

One outdoor test facility which was used to measure the diffuse solar heat gain through glass windows was pre- sented in the paper. The research on the diffuse solar heat gain was carried on. The numerical model was built and the experimental result was validated. The experimental data shows that the diffuse solar heat gain and exterior diffuse solar radiation were changed regularly with the time, both trends were in accordance with each other. Many experimental datas proved the test facility could be used to measure the diffuse solar heat gain.
