Such result it will follow in circulation degree of classroom and there is circulation degree of classroom possibility the CO₂ consistency changing. According to the result of TVOC, the result showed 7 times higher rate than the compared regulated standard of government. also as in the ventilation situation the rate showed twice times higher rate showing the seriousness of the matter.
