초록

최근 만들어지고 있는 거주공간은 단열성능 향상을 통한 냉난방 에너지 절약을 위하여 더욱 기밀해지고 있다. 이로 인해 일상생활 중에 발생하는 수분의 인위적인 배출과 외부공기의 인위적인 유입이 줄어듦에 따라 건축내장재의 자연조습기능에 대한 관심이 증대하고 있다. 본 연구에서는 열처리된 잣나무의 흡 방습성능을 평가하고 이에 영향을 미치는 인자들을 분석하였다. 상대습도 변화에 따른 평형함수율과 흡 방습률을 측정하였고, 조도(거칠기)와 미시적 표면형상, 그리고 FT-IR spectrum과 흡방습성과의 관계를 고찰하였다. 본 연구결과는 거주공간의 조습성능 정량화 평가시스템 구축을 위한 기초자료로 활용될 수 있을 것이라 기대된다.

A high airtightness is required for the residential spaces constructed recently to save cooling and heating energy through improving insulation performance. Because the chances to release steam formed by human activity in building and inflow of water vapor in outdoor air to residential space are reduced, the natural humidity control performance of interior materials has become more important. In this study, hygroscopic performance of thermo-physically treated wood (Pinus koraiensis) was estimated. At various relative humidity condition, the water vapor adsorption and desorption rates of wooden materials were measured as well as equilibrium moisture content. Effects of roughness and surface microstructure as physical factors and functional groups as chemical factors on the hygroscopicity were analyzed. It is expected that the results from this study and further study of measuring moisture generation in residential spaces could contribute to install a system for evaluating the hygrothermal performance of wooden building.
