Abstract in brief

  • This study used computational fluid dynamics (CFD) simulations to evaluate how effective upper-room UVGI systems are when combined with ceiling fans at disinfecting indoor air, considering different fan speeds and air exchange rates.
  • The findings showed that the air exchange rate was the most important factor affecting disinfection performance, but using ceiling fans could also enhance the effectiveness of UVGI systems by improving air circulation.
  • The research also explored how the ceiling fans influence UV disinfection efficiency and assessed outcomes like microorganism reduction and infection risk using various metrics, including the Wells-Riley equation.]

@ExtroSpecteur @Don_Milton @ON_LIGHT_fr @Lightdis_ @BarryHunt008 @sirhillarys CFD modeling has also predicted significant performance improvements when ceiling fans are used (but found that overall air change rate was more important). 3/3 https://t.co/9O82W9Q8oj
