| 요약2 | The objective of this study is to investigate the correlation of particle infiltration and building airtightness according to the deterioration of apartment housing units. For this purpose, the blower door test and particle infiltration experiments were conducted in 6 apartment housing units. The blower door test was conducted to measure the airtightness and the leakage area of suspected particle penetration pathways. The infiltration test method was performed to estimate the size-resolved particle penetration coefficient (P), infiltration factors (Finf), and outdoor particle infiltration rate (P×λ). During the infiltration test, the indoor and outdoor pressure difference was maintained at 10Pa using the blower-door depressurization procedure. The blower door test results showed that the difference in the airtightness level of leaky and average airtight housing units was about 2.5 times. The particle infiltration test results showed that the penetration coefficient (P), infiltration factor (Finf), and outdoor particle infiltration rate (P×λ) tended to decrease as the particle diameter increases. This result means that small particle size can easily pass through the crack in the envelope of the building. According to the results of the relationship between infiltration and airtightness, it was analyzed that the indoor particle concentration of leaky housing units could be 4.34 times higher than average airtight housing units under the same outdoor particle concentration condition. The results suggest that the required amount of particle removal may differ depending on the airtightness of the building. |
