초록
Purpose : When natural disaster occurs, the victims are evacuated to temporary shelters such asindoor gymnasiums or large space buildings until their homes are recovered. If someone in thistemporary shelter is infected with an airborne infectious disease, it becomes easier for the diseaseto spread to the other people in the shelter than it would be under normal conditions. Therefore,temporary shelters need to provide not only water and food but also hygienic indoor conditions. Methods : In this study, the use of mechanical systems such as ultraviolet germicidal irradiation(UVGI) systems and air cleaners were simulated using numerical analysis to find out how thesesystems can control airborne infection in temporary shelters. An indoor gymnasium was selected asa temporary shelter for the numerical simulation model considering Korea's post-disaster responsesystem. Influenza A virus was assumed as an airborne infectious disease and the diffusion of thevirus was made by one person in the shelter. Results : The result of this study showed that the UVGIsystems disinfected the virus more effectively than the air cleaners by creating a more stable airflowafter the disinfection process. The air cleaners could remove the virus but since it created anunstable airflow in the temporary shelter, the virus was condensed to a certain area to show ahigher virus concentration level than the source location. Implications : In the temporary shelter, itis necessary to use UVGI systems or air cleaners for hygienic indoor conditions.
