- W3201412139 abstract "The purpose of this study is to analyze the increase of PM2.5 concentration generated during cooking in a daycare center and the effect of removing countermeasures was analyzed by simulation method. The concentration of PM2.5 exceeded the upper limit of the relevant guidelines when cooking in the kitchen. The PM2.5 was moved from the cooking room to the staircase through the corridor. When the hood was operated under this condition, about 64.3% of PM2.5 was removed. However, when the hood was operated in the kitchen, negative pressure was generated and air flew into the child-care room, and the concentration of PM2.5 in the child-care room increased due to the influx of high PM2.5 concentration. The PM2.5 concentrations in the child-care rooms at the third floor and rooftop were also reduced by about 50%. In this situation, even if the children were active in the child-care rooms, the PM2.5 concentration in the cooking room was not significantly different. However, since the increased PM2.5 concentration, resulting from children’s activities, exceeded the standard value countermeasures to remove it were necessary. When the ventilation system was operated as a countermeasure to eliminate this, the average removal effect was 76% and all child-care rooms, except the one on the first floor, met the standard value. In addition, when the air cleaner was operated, it showed an average of 56% removal performance and the results were higher than the standard value in all child-care rooms where children were active. Lastly, when the ventilation system and the air cleaner were operated at the same time, the average removal effect was 80% and PM2.5 concentration in the child-care room on the first floor could not be solved by the ventilation system alone, it was maintained below the standard value using an air cleaner." @default.
