【摘要】：适应性热舒适研究表明,受地域气候、文化、居民生活习惯等方面的影响,我国不同气候区人体适应性热舒适存在差异。吐鲁番属于我国寒冷气候区,气候特征为干冷干热,与该气候区其他地域存在显著差异。那么,吐鲁番地区人体热适应性及热舒适区范围是否与寒冷气候区其他地域相同?针对此问题,本文在吐鲁番农村地区开展了大量热舒适现场调研工作,分析了该地区人体热适应性,热环境评价标准在吐鲁番农村地区的适用情况,建立了适用于评价吐鲁番农宅室内热环境模型。主要包括以下内容:首先,于春季、夏季、冬季分别进行了热舒适现场调查,分析了该地区人体热适应规律,并与寒冷气候区其他地域进行比较。结果显示,吐鲁番地区实测热中性温度分别为26.17℃(春季)、26.58℃(夏季)、18.99℃(冬季),夏季热中性温度明显高于寒冷气候区其他地域;全年80%可接受温度范围为12.28℃~25.99℃,较其他地域可接受温度范围宽泛;当夏季操作温度高于30℃时,当地居民服装不再发生明显变化,服装热阻约为0.4clo,也与其他地域存在较大差异。由此表明,吐鲁番农村居民热适应规律与寒冷气候区其他地域不同。其次,分析了ASHRAE 55、EN 15251及GB/T 50785标准在吐鲁番农村民居室内热环境评价的适用性。吐鲁番地区室外温度皆超出上述三个标准规定的适用温度范围,且GB/T 50785标准中的计算法评价方式未考虑吐鲁番地区与寒冷气候区适应水平的差异。表明,需单独制定适用于该地区的评价模型。再次,根据ASHRAE 55确定室内热环境等级的方法,得到80%人群满意的适应性热舒适区范围,上限方程为y=0.2964x+25.901,下限方程为y=0.3194x+14.879;根据GB/T 50785计算自适应系数λ的计算方法,得到λ=-1.46(春)、λ=0.77(夏)、λ=-0.49(冬);最后,对吐鲁番农村不同建造时期、不同建筑材料的农宅分别于春季、夏季、冬季进行室内热环境测试,结果表明,本文建立的适应性热舒适评价模型,在评价吐鲁番地区农宅室内热环境时与热舒适现场调研得出的结果基本一致。本文对吐鲁番地区热舒适现场调查数据及形成的各项结论,对研究同一气候区不同气候特征条件下,人体热适应规律及室内热环境评价具有参考意义,为我国室内热环境评价标准后期修订与完善提供数据支持。
[Abstract]:The study of adaptive thermal comfort shows that there are differences in adaptive thermal comfort of human body in different climatic regions in China under the influence of regional climate, culture and residents' living habits and so on. Turpan belongs to the cold climate region of China, and its climatic characteristics are dry, cold, dry and hot, which are obviously different from other regions in this climate area. So, is the thermal adaptability and thermal comfort zone of the Turpan area the same as other regions of the cold climate zone? In order to solve this problem, this paper has carried out a large number of field investigations on thermal comfort in the rural areas of Turpan, and analyzed the applicability of the thermal adaptability and thermal environment evaluation criteria in the rural areas of Turpan. A model for evaluating the indoor thermal environment of agricultural houses in Turpan was established. The main contents are as follows: firstly, the thermal comfort field investigation was carried out in spring, summer and winter, and the rules of human body thermal adaptation in this area were analyzed, and compared with other regions in cold climate area. The results show that the measured thermal neutral temperatures in Turpan are 26.17 鈩，
