摘要
本文针对哈尔滨某生鲜超市,利用COMSOL仿真软件,模拟分析了五种自然通风方式下病毒扩散规律,得出了开门通风和门窗同开通风排污效果最好,并分析了其排污特性。在降低一定热舒适性的前提下,提出了每小时门窗同开通风1-2分钟,或者开门通风2-3分钟,能够快速降低超市内部空气的病毒浓度,明显降低室内人员交叉感染风险。
In this paper,the law of virus diffusion under five kinds of natural ventilation in the commodity supermarket is simulated and analyzed using COMSOL simulation software.It is concluded that the effect of opening door ventilation and opening the doors and windows ventilation is the best,and the characteristics of pollution discharge are analyzed.On the premise of reducing certain thermal comfort,it is proposed that opening the doors and windows for 1-2 minutes or opening the door for ventilation for 2-3 minutes per hour can quickly reduce the virus concentration in indoor air and significantly reduce the risk of cross infection of indoor personnel.
