摘要
对外呼吸式双层皮玻璃幕墙在太阳辐射下的自然通风的实验测试方法进行研究,并应用该方法对某双层皮幕墙在多种太阳高度角下的通风量和温度分布进行测量。根据实验结果,总结不同太阳高度角下双层皮热压自然通风的通风量和温度分布规律,分析双层皮空腔内热压自然通风的气流形态。应用实验结果,分析透过外层玻璃进入幕墙的太阳辐射能量中,通过通风排热带走的热量、透射进入室内的短波辐射量以及通过内玻向室内的传热量分别所占的比例,进而全面分析外呼吸式双层皮幕墙系统遮阳、通风、隔热的特征和性能。
Experimental methods for testing the natural ventilation performance in double skin facade (DSF) were promoted. The temperature distributions and airflow rates in an external respiration DSF under different solar alti- tude angles were measured and summarized. Airflow configuration in the DSF cavity was analyzed according to the experimental results. Energy flow in the DSF system was calculated and the performance of shading, ventilating and insulating of the DSF system was discussed.
