摘要
为应对新型冠状病毒肺炎疫情的暴发,武汉市建造了火神山和雷神山这两座应急医院以缓解现有医疗系统的压力。为了避免应急医院医患的交叉感染,雷神山医院病房的通风系统需要针对性地设计病房的通风系统。该文借助CFD技术对雷神山医院的负压病房通风系统进行了有害气体扩散分析,从而定量把握病房内含病毒的有害空气浓度,从而为通风系统的设计优化提供建议。另外,基于病房内有害气体的浓度分布情况,也可为传染病医院的防疫工作提供参考。
Huoshenshan Hospital and Leishenshan Hospital have been built in Wuhan to tackle with the COVID-19 outbreaks,which relieves the pressure of medical system.In Leishenshan Hospital,the ventilation system should be designed to anti-epidemic according to the high infectivity of COVID-19.In this paper,the CFD technique was applied to the design of ventilation system of negative pressure ward in Leishenshan Hospital.The concentration of the harmful air with virus in the ward could be obtain,which would provide suggestions for design optimization.In addition,the distribution of the harmful air in ward would be useful for epidemic prevention.
