Abstract

Recently, the concerns in the risk for PM (Particulate Matter) has increased. To reduce PM in residential space, Air cleaning ventilation system that is equipped with filtering technologies are being suggested. Particle matters, unlike other gas pollutants or CO₂, have little influence on concentration diffusion. So, the consideration of the Air Change Rate and location of SA·RA is needed. Thus, this study analyzed indoor PM concentration change by Air change rate of Air cleaning ventilation system and locations of SA (Supply Air)·RA (Return Air). The result showed the increase in Air change Rate and location of SA have a significant effect on indoor ∅ 2.5 ㎛ Particle concentration changes.
