摘要
实现体育场馆智慧健康环境控制,对改善体育场馆室内环境品质、保障公众健康具有重要意义。现有研究对于体育场馆的室内环境承载力研究较少,对于体育场馆最大安全容纳人员数量尚不清楚。因此,本文对我国华北地区某体育场馆的环境承载力开展了案例研究,并分析了体育场馆不同房间的人员安全风险。结果表明:对于观众包厢,当室内人员都佩戴口罩时,可使流感感染风险从29%降低至1%以下;对于运动员休息室和记者工作室,仅供应新风系统新风,可使室内人员的流感感染风险均在10%以下。在现有新风量下,房间的CO_(2)承载力都达到设计人数要求,其中记者工作室的承载力远高于其设计人数要求。并通过设置室内净化器,可显著降低体育场馆室内人员的PM2.5浓度风险。本文研究结果预期为体育场馆的室内环境控制提供经验参考与数据支撑。
Achieving intelligent and healthy environmental control in sports venues is of great significance to improving the indoor environmental quality of sports venues and ensuring public health.Few of existing research has delved into the indoor environmental carrying capacity of sports venues,with the maximum safe capacity of sports venues still unclear.Therefore,this paper conducted a case study of the environmental carrying capacity of a sports venue in North China,and analyzed the personnel safety risks in different rooms of the sports venue.The results showed that the risk of influenza infection can be reduced from 29%to less than 1%when people all wear masks in boxes for the audience;in athletes’lounges and reporters’work rooms,only supplying fresh air from the fresh air system can keep the influenza infection risk for indoor personnel below 10%.Under the existing fresh air volume,the CO_(2)carrying capacity of all the rooms meets the design capacity requirements,among which the carrying capacity of the reporters’work rooms is far higher than their design capacity.By setting up indoor purifiers,the PM2.5 concentration risk for indoor personnel in sports venues can be significantly reduced.The research results are expected to provide experience reference and data support for the indoor environmental control of sports venues.
