【摘要】 为了解夯土民居春夏潮湿季节室内热环境特点,对重庆地区典型夯土民居进行了春夏两季的热环境测试。结果显示:在温度舒适的天气,室内外温度接近,但是室内潮湿状况严重;在温度较高的天气,夯土围护结构隔热效果明显,室内热环境较舒适。夯土围护结构在阴雨天气,吸收空气中的湿度,能降低室内潮湿程度;在晴朗天气,室内温度升高时,释放湿气。但是由于夯土民居开窗面积的制约,室内空气流通性差,使湿气在室内积累,难以散发至室外。通过合理控制窗户开闭与利用排风措施控制室内湿度,增强屋顶隔热性是提高夯土民居室内热环境的重要措施。更多还原

【Abstract】 In this paper,the indoor thermal environment of a rammed earth dwelling in Chongqing was measured for a long period in spring and summer,aiming at the characteristics of indoor thermal environment of rammed earth dwelling in damp season. Results showed that,in mild weather,the indoor temperature was close to the outdoor temperature,but it was highly humid indoor; while in hot weather,the heat insulation effect of rammed earth envelope was remarkable,which made indoor thermal environment comfortable. Rammed earth envelope absorbed the moisture from the air in rainy weather,which could reduce indoor humidity; in fine weather,moistures were released due to temperature rising. For the restriction of the small window of rammed earth dwelling,which gave rise to poor indoor air liquidity,the air moisture accumulated indoors and was hard to be sent out to the outside. To control the moisture in or out through reasonable operation of the window or by exhaust equipment,and to strengthen the insulating roof stays are feasible measures to improve the indoor thermal environment of the rammed earth dwelling.更多还原
