COVID-19 감염 위험률 산출 시 환기량 예측 방법 검토

다국어 초록 (Multilingual Abstract)

The Wells-Riley equation, which calculates ventilation rate, has been widely used to estimate the risk of COVID-19 infection. Sufficient ventilation that supplies outdoor air into indoor spaces has been proven effective in preventing the spread of the virus indoors by diluting its concentration. This paper aims to present a methodology for estimating ventilation rates during occupancy periods for calculating infection risk. Ventilation rates were estimated using occupant-generated carbon dioxide (CO2) based on the mass equilibrium equation. The analyzed spaces were university classrooms, where real-time occupancy and ventilation conditions (mechanical ventilation, window ventilation, mechanical and window ventilation, non-ventilated) were determined via video camera.
