A Sustainable Solution for Improved Indoor Air Quality in a COVID Era
A key component of sustainability is healthy indoor air quality. This topic has gained more attention during the COVID-19 pandemic. Several studies point out that the recommended 6 feet distance is not very effective in an indoor environment. A credible solution to the problem of indoor viral dissemination has been proposed here. Using the principles of computational fluid dynamics and modeling two different indoor office areas, the way in which viral sneeze droplets and aerosols from infected people spread in an indoor setting (with HVAC) has been revealed. A thorough validation of the methods has been conducted using measured temperature and velocity profiles in an experimental chamber under a controlled environment. The study also details the design of a novel air sterilization unit, named RM3, that is capable of drastically reducing the viral spread through aerosol as well as fomite transmission.
