摘　　要：屋面的保温隔热性能对顶层房间的能耗及室内热舒适性有着非常重要的影响。屋面蓄水砖是利用空气间层隔热和蒸发降温的原理而制作的产品。从蓄水屋面砖蓄水深度方面来研究屋面蓄水砖的隔热保温性能,并对其隔热保温性能进行系统的实验测试分析,对比分析蓄水砖下屋面温度与裸露屋面温度及室外空气温度的变化规律及特征。通过实验发现水深为8cm时效果最佳。为优化蓄水屋面的构造提供依据。Roof insulation performance has an important influence on the energy consumption and comfort of the top room. Water-retaining roof brick has the insulation effect by air layer and water evaporating. This paper mainly researches the insulation performance of the water-retaining roof brick with different water depth. Through the on-the-spot experiments. Comparative analyze that the roof temperature under water-retaining roof brick and the temperature without water-retaining roof brick change with the variation outdoor air temperature by on-the-spot testing. It was found that the water-retaining roof brick works best when the water depth is 8 cm through the series experiments. Provide the basis for optimizing the structure of the water storage roof.
