Application of Mobile Air Cleaning Devices in daily school routines

Abstract

The spread of the SARS Cov2 virus in Europe clearly reveals the need of new ventilation concepts. Schools are considered to be one of the main origins of the spread. Therefore, ways to reduce the possibility of indirect infection in everyday school life are investigated. In this paper, the results of field studies are presented. In the course of these studies, different modes of action (filtration, UV-C, photo-catalysis) and room flow concepts (mixed ventilation, displacement ventilation) were considered. The evaluations of the measurements show how the devices influence the sensations of the students (sound pressure level, draught risk, etc.). Furthermore, it shows how the exhaust air capture works and how the room flow is affected. Therefore, ways to reduce the possibility of indirect infection in everyday school life are sought here.
