New York, Aug 13 (TIWN) With schools set to open in many places, researchers at the Massachusetts Institute of Technology (MIT) suggest that open windows and good heating, ventilation, and air conditioning (HVAC) systems can help keep the classrooms safe during the Covid-19 pandemic.
The study also shows how specific classroom configurations may affect air quality and necessitate additional measures, beyond HVAC use or open windows, to reduce the spread of aerosols -- those tiny, potentially Covid-carrying particles that can stay suspended in the air for hours.
