실내환경변화에 따른 박물관 전시케이스의 동적 특성

This study was undertaken to examine the effect of the airtightness and amount of the adsorption material on the variation of the relative humidity inside the exhibition case. An infiltration model, with and without the adsorption material, of the exhibition case was developed and calculated the relative humidity inside the exhibition case using the explicit numerical method. We know that the air-tightened ability of the exhibition case can be evaluated by the mass change rates of gases which are an important factor responsible for the deterioration of artifacts. The results show that the amount of the adsorption material play an important role in the variation and the position of the convergence of the relative humidity inside case when the airtightness of an exhibition case is lower. And when the kind of the artifact and the airtightness of an exhibition case are known, we can calculated the amount of the adsorption material using our numerical simulation program.
