摘要
伴随着全球气候变暖,夏季高温高热天气增多。由于学生宿舍普遍通风不良,宿舍内热环境质量越来越差,严重影响了学生的学习效率与睡眠质量。为了改善西北地区学生宿舍的热环境及通风问题,同时考虑到能耗因素,笔者所在单位根据西北地区的特点,充分利用西北地区丰富的可再生能源——干空气能,联合澳蓝(福建)实业有限公司共同研发了应用于西北干燥地区宿舍用的窗式蒸发冷却空调器,并在笔者所在单位的学生宿舍安装测试。通过调查该宿舍楼的建筑围护结构,室内热湿调控等情况,并结合安装该空调器后的实际测试效果,进行了分析研究,并对经济、环境效益进行分析。同时,对该空调器进一步推广应用提出了改进意见。测试及调查表明:目前该建筑围护结构隔热保温性能较差,室内现有的热湿调控措施缺乏,学生对夏季宿舍的热环境满意度较低,使用该窗式空调器后室内热环境得到很大改善,同时室内的空气品质也得到了较大程度的改善。
The summer days of high temperature and heat weather increased with glob- al warming. Due to the poor ventilation in the dormitory, the quality of the thermal envi- ronment in the dormitory is getting worse, which seriously affects the students＇ learning efficiency and sleep quality. In order to improve the thermal environment and ventilation of the dormitories in northwest China, the author of this paper makes full use of the rich renewable energy-dry air energy in northwest China, taking into account the energy con- sumption, developed the window-type evaporative cooling air conditioner apply to dry area in northwest China combined with the Aolan industry company, and made installation test in the dormitory of author＇s school. Analysed the economic and environmental benefits through the survey of the building envelope, indoor heat and humidity control and com- bined with the actual test results after installed the air conditioner. Also put forward the improvement suggestions to the further application of the air conditioner. Test and inves- tigation shows that the thermal insulation performance of the building envelope is poor, the existing indoor heat and humidity control measures are lacking, the students＇ satisfac- tion with the thermal environment of the summer dormitory is low, the indoor thermal en- vironment and air quality has been greatly improved after using the window-type evapora- tive air conditioner.
