Influence of ventilation and air cleaning on the concentration of endogenous aerosols during sports activities

V notranjem okolju je koncentracija aerosolov povezana z aktivnostjo ljudi, prezračevanjem in filtriranjem delcev. Okužba z boleznijo je lahko posledica aerogenega prenosa patogenih aerosolov. Z eksperimentom ocenimo razmerje med koncentracijo endogenih in eksogenih delcev ob izvedbi fizične aktivnosti. Izvedemo različne scenarije meritev, kjer spremenljivke predstavljajo prisotnost in odsotnost prezračevanja, čiščenja zraka ter aktivnosti ljudi. Dokažemo rast koncentracije endogenih aerosolov ob izvedbi fizične aktivnosti in učinkovitost naravnega prezračevanja in čiščenja zraka.In indoor environments, aerosol concentration is associated with human activity, ventilation, and air cleaning. An infection with a disease can be a consequence of aerogenic transmission of pathogenic aerosols. We evaluated the ratio between the concentration of endogenous and exogenous particles during physical activity. We analyzed various measurement scenarios where the variables represent the presence and absence of ventilation, air cleaning, and human activity. We demonstrate the increase in the concentration of endogenous aerosols during physical activity and the effectiveness of natural ventilation and air purification
