新型冠状病毒肺炎疫情与集中空调系统
COVID-19 epidemic and central air conditioning systems
摘要：
新型冠状病毒可以通过空气传播，但是否会通过集中空调通风系统传播尚无定论。认为空调气流在有新型冠状病毒感染者的房间内是导致聚集性感染的重要原因。疫情期间集中空调系统关闭回风，采用全新风运行模式的合理性值得商榷，而采取有效防范措施的集中空调系统可大幅度降低室内病毒浓度，应可以使用；研究和开发行之有效的空气净化技术和设备是防范流行性疾病传播的重要举措。
Abstract：
2019-nCoV can be transmitted through the air, but whether it will be transmitted through central air conditioning and ventilation system is still uncertain. Thinks that air conditioning airflow in rooms with COVID-19 infection is an important cause of cluster infection. During the epidemic period, the rationality of the operation mode using full fresh air without return air for central air conditioning system is questionable. The central air conditioning system with effective preventive measures can greatly reduce the indoor virus concentration, which should be used. Research and development of effective air purification technology and equipment is an important measure to prevent the spread of epidemic diseases.
