摘　　要：以桂林某高校学生宿舍为例,运用PKPM-CFD软件将风速、风流场与空气龄按照《绿色建筑评价标准》对夏热冬冷地区内廊式和内院式两种不同学生宿舍布局的室内风环境进行模拟对比分析。结果表明:在两种方案的朝向窗墙比均为0.10、外窗开启面积比例均为50%左右的情况下,内院式学生宿舍的自然通风环境明显好于内廊式,各房间的风速、风流场和空气龄不但得到明显改善,并且比较均匀,从而确定内院式学生宿舍的自然通风环境优于内廊式学生宿舍。As the main buildings in campus,the resource and energy consumption of student dormitory become the focus of attention in the energy-saving effort and providing a good indoor ventilation environment for dormitory buildings.A college dormitory in Guilin is taken as an example.According to“Green Building Evaluation Standardand”by PKPM-CFD software,the wind speed,wind field and air age are all measurement standards to simulate and compare the indoor wind environment of the inner corridor and inner courtyard student dormitories in cold winter and hot summer.The results show that both schemes have a window-to-wall ratio of 0.10.The ratio of the open area of the external windows is about 50%.However,the natural ventilation environment of the inner courtyard dormitory is significantly better than that of the inner corridor dormitory.The wind speed,air flow field and air age of each room can not only be significantly improved,but also relatively remain constant.So the natural ventilation environment of the inner courtyard dormitory is better than that of the inner corridor dormitory.
