【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。更多还原

【Abstract】 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.更多还原
