The purpose of the study is to discuss the appropriate HVAC operations in civil buildings from a perspective of engineering experience, to provide a safe and healthy indoor environment for working and living, responding to the prevention of COVID-19 transmission in buildings. The study reviewed the previous theoretical studies of relations between increased ventilation and the transmission of the virus, and based on a premise of value orientation, addressed that increasing the ventilation was still one of the most effective ways to promote the anti-epidemic property in the buildings. The study thus summarized the current characteristics of different HVAC systems in buildings, and put forward the target operation strategies respectively, which effectively increased the fresh air flow rate and meantime ensure the normal operation of the buildings. Suggestions as to the anti-epidemic designs for the newly constructed buildings were further presented. The outcomes of HVAC operation strategies are beneficial for instructing the normal operation of the building HVAC systems in the epidemic.
本研究的目的是从工程经验的角度探讨民用建筑中适当的暖通空调运行方式，为工作和生活提供安全健康的室内环境，以应对建筑物内新型冠状病毒肺炎的传播防控。该研究回顾了以往关于增加通风与病毒传播之间关系的理论研究，并基于价值取向的前提指出，增加通风仍然是提升建筑物抗疫性能的最有效方法之一。该研究总结了建筑物中不同暖通空调系统的当前特点，并分别提出了目标运行策略，有效提高了新风流量，同时确保了建筑物的正常运行。进一步提出了新建建筑的抗疫设计建议。暖通空调运行策略的成果有利于指导疫情期间建筑暖通空调系统的正常运行。
