摘　　要：2020年上半年新型冠状病毒疫情爆发,上海图书馆东馆的施工建设受到了一定的影响。随着时间的推移,疫情在全球多地蔓延,国内疫情虽然得到了有效的控制,但是如此重大的公共卫生事件,也给社会各界的常态防控敲响了警钟。国内各部委陆续出台了针对疫情防控的空调系统使用指南、措施和规范。对标这些新出台的规范和标准,上海图书馆东馆空调系统原设计满足现行规范对于人均新风量和过滤等级的要求,可以开启运行。为进一步提高安全等级,结合分析上海图书馆东馆已经处于建设施工尾声的实际情况,研究给出具体针对过滤装置的改进措施并探讨防疫期间的空调系统使用指导原则。研究提出的5条改进及运行措施:①加强自然通风,②控制在室人流量,③增配净化过滤装置,④依据疫情风险等级加大空调新风量,⑤加强对空调设备的清洗、消毒、检查。对于同类型的公共建筑有一定的借鉴意义。In the first half of 2020, the construction of Shanghai Library(East Zone) was delayed by the COVID-19’s outbreak. As time goes on, the epidemic is spreading in many parts of the world. Although the epidemic in China has been effectively controlled, such grave public health emergencies ring the alarm bell for social public. Relative authorities have issued guidelines, measures and specifications for how to use HVAC system under these circumstances. By analyzing these new codes and standards, the HVAC system in Shanghai Library(East Zone) can operate as design. Because the design outdoor air rates and filter’s performance meet the standard requirements. At the end of Shanghai Library East’s construction, some operation methods and adaptable improvements in filters are given to increase the security level. Five methods, including:①enhancement of natural ventilation,②control of the occupant density,③installation of filters,④increase of the outdoor air rates for ventilation according to the risk level of epidemic situation,⑤cleaning, disinfection and inspection of the HVAC equipment. Given by this research can also be applied to similar public buildings.
