| 요약2 | Indoor particle concentration is partly affected by penetration of outdoor particle through building envelopes. Therefore, understanding particle penetration phenomenon in buildings is crucial for evaluation of indoor air pollution caused by fine particle. The objective of the present work is to investigate the impact of outdoor dust on indoor dust level in residential buildings. Field measurements to examine concentration ratio between indoor and outdoor particles (I/O ratio) were carried out in a residential housing unit located in Daegu, Korea. The I/O ratio of size-resolved particle, ranging from 0.3μm to 10.0μm, was compared to examine the impact of outdoor particle on indoors. The results showed that the I/O ratio of small particle (less than 1.0μm) is higher than that of large particle(larger than 3.0μm). The study also showed that the I/O ratio in the day with higher infiltration was higher in the day with lower infiltration, indicating that the building infiltration rate is related to particle penetration. |
