摘要
对北京某大型商业建筑的中庭区域进行CFD模拟分析,分别验证了中庭及回廊区域在冬季空调工况、夏季非空调工况、夏季未设遮阳帘以及夏季设置遮阳帘空调工况下的室内的温度场,模拟结果现实,冬季工况下,中庭区域空气温度与平均辐射表面温度均符合舒适性要求;夏季空调工况下,未设遮阳帘时,室内空气温度符合设计工况,而地面和吊顶局部表面温度较高,会造成人体不舒适性增加;当设置遮阳帘后,室内空气温度及内表面平均辐射温度均符合舒适性要求。
This report carries out CFD simulation analysis on the atrium area of a large commercial building in Beijing,and verifies the indoor temperature field of atrium and cloister area under air conditioning condition in winter,non air conditioning condition in summer,no sunshade curtain in summer and sunshade curtain air conditioning condition in summer.The simulation results show that the air temperature of atrium area is consistent with the average radiation surface temperature in winter Comfort requirements:under the air conditioning condition in summer,when there is no sunshade,the indoor air temperature meets the design condition,while the local surface temperature of the ground and ceiling is higher,which will increase the human discomfort;when the sunshade is set,the indoor air temperature and the average radiation temperature of the inner surface meet the comfort requirements.
