西安咸阳国际机场T3航站楼空调系统新冠病毒传播风险分析
Transmission risk analysis of SARS-CoV-2 in air conditioning systems of Terminal 3 of Xi’an Xianyang International Airport
摘要：
机场航站楼作为出入境的重点场所，承担着我国新型冠状病毒肺炎疫情防控的重要责任。本文对西安咸阳国际机场T3航站楼国际指廊空调系统进行简介，分析了病毒传播特性与空调系统之间的关系，使用Wells-Riley模型对国际指廊病毒感染风险进行了计算。结果显示，国际到达区域感染风险不足1%，国际等待区域感染风险不足2%，西安咸阳国际机场空调系统造成病毒传播的概率极其微小。
Abstract：
The airport terminal is the top priority of the SARS-CoV-2 prevention and control. This paper presents the air conditioning system of Terminal 3 of Xi’an Xianyang International Airport briefly. The relationship between SARS-CoV-2 transmission characteristics and air conditioning system is analysed and the infection risk is calculated by the Wells-Riley model. The results show that the infection risk in the international arrival area is less than 1%, and the infection risk in the international waiting area is less than 2%. It is concluded that the probability of SARS-CoV-2 transmission caused by the air conditioning system of Xi’an Xianyang International Airport is extremely small.
