Air currents created by the HVAC system affect the movement of infectious aerosols (that can carry viruses like COVID-19) in the indoor environment. This affects the infection risk and the safety of the occupants in your space. CFD is a tool that can be used to predict the movement and concentration of infectious aerosols in your space. Retrofits to the HVAC system can therefore be evaluated on how well they reduce the spread of infectious aerosols.
We are not doctors or infectious disease transmission experts and we recognize that the airborne route is not the only mode of transmission. We are a team of engineers with over a decade of experience in designing air distribution systems for indoor environments. We use CFD simulations to predict the impact of the air distribution system on where potentially infectious aerosols will travel within an indoor environment. Recommendations that can lower the airborne concentrations of those aerosols are made based on simulation results. Adjusting the air distribution system to lower aerosol concentrations in the occupants breathing zone can reduce the risk of infection from the airborne infection route.
