【摘要】 根据屋面构造做法和材料的不同 ,本文对自由水表面被动蒸发屋面、多孔材料蓄水屋面以及吸湿被动蒸发屋面等 3类屋面被动蒸发隔热技术进行了分析探讨 ,论证了各类被动蒸发隔热屋面的隔热机理、隔热效果以及适用气候条件或地区。研究结果表明 :由于水的比热大且水分蒸发时能吸收大量的汽化潜热 ,各类被动蒸发屋顶都具有较好的保温隔热性能 ,工程实践中可根据当地的气候条件、资源环境状况以及经济发展水平进行合理选用。更多还原

【Abstract】 According to different construction ways and materials, three kinds of roof, that is ,passive evaporated roof with freedom water surface , water stored roof by means of pore material and hygroscopic roof,are introduced in this paper . Meanwhile the theory of heat insulation and energy efficiency on passive evaporation roofs and suitable weather and places to be used are also discussed .The results show that all kinds of passive evaporated roofs have high efficiency in heat insulation because of water’s high specific heat and large quantity of absorbed latent heat,and that they can be adopted according to the practical local weather ,natural resource and economical development.更多还原
