针对自然通风对住宅室内热环境的影响,选取室内热环境状况较为恶劣、风资源贫乏的重庆市住宅为例,通过i-d图分析了自然通风在改善住宅建筑热环境,提高人体热舒适的可行性;并通过对典型居民住宅的现场实测数据,进行了室内平均预测投票-预测不满意百分比热舒适评价。研究结果表明:即使在风资源贫乏的城市,住宅建筑良好的自然通风既能大量地节约建筑能耗,也能够极大地改善室内热环境,尤其是过渡季节及夏季阴雨天气。
A typical residential housing in Chongqing is taken as an example, which is with worse natural climate conditions and absent of wind resource. A feasibility study on improving the thermal environment by natural ventilation is analyzed based on the i-d chart. By the on-site tests,the indoor thermal comfort is evaluated based on the PMV-PPD methodology. Better natural ventilation can not only save the building energy consumption, but also improve indoor thermal environment, especially in the rain and transition seasons, even in the urban area with poor wind resource.
