Discussion on HVAC system design for healthy office buildings in post-epidemic period

Through the research on the relevant contents of HVAC systems in healthy building systems at home and abroad, this paper sorts out key design points of HVAC system for healthy office buildings in the post-epidemic period. This paper focuses on the methods of dealing with the epidemic situation of the air conditioning and ventilation system in office buildings from three aspects:influence of HVAC system on virus propagation, HVAC system design standards for normal and epidemic conditions, and epidemic prevention strategies. At the same time, the effects of increasing outdoor air volume and changing air conditioning operation temperature on the energy consumption and cooling and heating load of the system during the epidemic are analysed.
