What Does HVAC Need for the New COVID-19 Challenges?
People usually spend 90% of their time in buildings. And air transmission is a typical way of transmission of the COVID-19 virus. Thus, people may be infected by the virus transmitted through the HVAC system of the buildings. There are many types of building HVAC systems. It is a big challenge to prevent the spread of the virus in the context of the pandemic. This report will analyze the possible virus transmission pathways in different building HVAC systems, as well as the removal ability of the existing air purification technologies. We will discuss the combination of HVAC systems and air purification technologies to prevent COVID-19 viruses from spreading in the building environment.
