This study compared and analyzed the indoor pollutant equation and CFD simulation to verify and validate the indoor pollutant prediction method based on complete diffusion in school classrooms. To solve indoor air quality (IAQ) problems, air cleaning and ventilation systems are mainly used for school classrooms. In classrooms with a large amount of air with ventilation and air cleaning devices, it is believed that the indoor pollutant prediction method considering complete diffusion can be applied. In this paper, to remove CO₂and PM2.5, the pollutant balance equation for improving indoor air quality is reviewed. The concentration of PM2.5 is more affected by the air volume of the ventilation device than the air cleaning device. As a result of applying the CFD simulation, the change in the concentration of CO2 is affected by the air volume of the air cleaning device. The CFD analysis results are almost similar to the analysis results based on complete diffusion, although errors of 3.57 to 7.69% for the PM2.5 concentration and 8.31 to 13.95% for the CO2 concentration are shown. In the case of interlocked control of ventilation and air cleaning devices, reliability is higher.
