摘　　要：在同一屋面区域分别建立了7个蓄水层高度相同、构造模式不同的蓄水隔热模块,并对其在自然气候控制条件下的隔热性及动态蒸发冷却特性进行了测试,通过与敞开式蓄水模块的对比,获得了不同构造模式下浅层遮挡式蓄水屋面隔热模块的隔热性能参数及其定量评价指标,找到了其动态蒸发冷却变化规律及特征,摸清了不同构造模式下浅层蓄水屋面隔热模块存在的问题及优点,为优化蓄水屋面隔热模块的构造和指导其工程实际应用提供了基本的实验依据。Seven different water-retaining roof modules that have the same water-retmnmg height hut chtlerent structure are built on the same roof, and the thermal insulation and evaporative cooling performance of the water-retaining roof that mentioned above are experimented in detail under the real weather controlling conditions. The thermal insulation characteristics and evaluation laws for water-retaining module of different structure modes are analyzed and derived from the experimental data, and the variation laws of dynamic evaporative cooling characteristics, and disadvantages and advantages of the modules are investigated and found on the basis of test. All these conclusions will be benefit for optimizing the structure of water-retaining roof and conducting the ap- plication of water-retaining roof in actual projects.
