The outbreak of pneumonia caused by 2019 Novel Coronavirus arises significant concern for virus transmission and control. The control of the indoor environment or public-enclosed environment is crucial to reduce the risk of infection. Heating, ventilation, air-conditioning (HVAC) systems are used to create a healthy, thermal-comfort indoor environments. Thus, the rational use of HVAC systems is of great importance for the environmental control to reduce infection risk and to improve human wellbeing in the pandemic. In order to satisfy the requirement of better healthy environment and more thermal comfort performance of indoor ventilation system, prevention of indoor pollution is essential, especially considering the purpose of disease transmission resistance. This paper investigated the collective contagion events in enclosed spaces as well as engineering control against virus spread with ventilation systems for health-care facilities and public vehicles. Future challenges of HVAC design and control were discussed.

用于环境控制的暖通空调系统，以最大限度地减少 COVID-19 感染

2019 年新型冠状病毒引起的肺炎疫情引起了人们对病毒传播和控制的高度关注。控制室内环境或公共封闭环境对于降低感染风险至关重要。采暖、通风、空调 (HVAC) 系统用于营造健康、热舒适的室内环境。因此，合理使用暖通空调系统对于环境控制以降低感染风险和改善大流行中的人类福祉具有重要意义。为了满足室内通风系统更好的健康环境和更好的热舒适性能的要求，预防室内污染至关重要，特别是考虑到抗病传播的目的。本文调查了封闭空间中的集体传染事件，以及通过卫生保健设施和公共车辆的通风系统对病毒传播的工程控制。讨论了 HVAC 设计和控制的未来挑战。
