DPM 모델을 이용한 환기시스템의 미세먼지 농도저감 성능 분석

Recently, as the concerns in the risk for PM(Particulate Matter) has increased, to solve the problem of PM, Research and development of ventilation system with filter system are actively being carried out. However, PM is less influenced by concentration diffusion. Thus, this study analyzed indoor PM concentration change by Air change rate using Computational Fluid Dynamics(CFD) analysis. The results showed that the concentration reduction of indoor PM was affected by Air change rate. Accordingly, in order to remove PM, the Air change rate of ventilation system applied to the residential space must be increased above the minimum standard. However, the problem of increased energy consumption and noise should also be considered.
