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.

该研究的目的是从工程经验的角度讨论民用建筑中适当的暖通空调操作，为工作和生活提供安全健康的室内环境，以应对建筑中 COVID-19 传播的预防。该研究回顾了以往关于增加通风与病毒传播关系的理论研究，并基于价值取向的前提，提出增加通风仍然是促进疫情防控的最有效途径之一。建筑物。研究总结了当前建筑不同暖通空调系统的特点，并分别提出了目标运行策略，有效提高了新风流量，同时保证了建筑的正常运行。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结果有利于指导建筑暖通空调系统在疫情中的正常运行。
