摘　　要：屋面隔热效果直接影响室内冷负荷大小,也是导致顶层房间制冷量增大的直接原因。选取无水的蓄水砖屋面与蓄水的蓄水砖屋面、不同盖板盖(开孔与不开孔)蓄水砖屋面两种工况的屋面进行测试,根据测试结果分析蓄水砖屋面的隔热效果,并探讨蓄水砖屋面一天24h的温度分布。研究结果表明:屋面蓄水利于隔热,蓄水的蓄水砖屋面隔热效果优于无水的蓄水砖屋面;不开孔盖板的蓄水砖比开孔盖板的蓄水砖隔热效果更优。既有建筑屋面节能改造可以铺设屋面蓄水砖改善屋面的隔热性能。Roof insulation has an impact on the indoor heat load and causes an increase in the heat on the top floor. This paper selects two conditions for testing：（1） comparing roof temperature using brick storage water, brick not storage water and an ordinary roof,（2） comparing different cover of water-retaining roof. Meanwhile, analyzing the distribution of bricks temperature in a whole day（24hous） from the test results. According to the test results, it shows that roof with water-retaining brick storage water is more insulated than the brick not storage water and cover with no hole insulation effect is better. For energy saving in existing buildings using a water-retaining roof will improve the performance of the roof insulation.
