The authors conducted 20 computer simulations of how particles could spread based on a classroom including nine students and an instructor and desks with and without glass screens on the front. “Aerosol distribution in the room is not uniform and is strongly influenced by air conditioning layout,” said the authors, from the University of New Mexico.
The authors said opening windows while the air conditioning was on increased the particles exiting the room and decreased particles deposited on those in the room.Ventilation from air conditioning systems reduces the number of particles in the air. However, since air flow is often recycled, the authors said particles exiting the classroom “may pose greater risk to individuals in other rooms.”
