Abstract

Although the importance of good conservation of historic sites including ancient royal tombs is well aware, still not much attention has been paid for the facilities and systems to preserve those historic sites, which includes precious artifacts as wall paints and carved works, etc. Even the general understanding about the environment of the underground space or tombs is not satisfactory. In the present study, vibration levels due to the operation of an HVAC system to maintain the desired indoor temperature and humidity are investigated experimentally. According to the measured data, the level of vibration inside the present model tomb with the indoor unit inside, showed order of magnitude less values than the Swiss Standards, but still higher than the value suggested by German standards, which is, zero. Further study will be pursued for cases including different ways of installation, because the vibration level depends not only on the system design, but also on the installation methods.

문화재적 가치를 지닌 고분의 장기보존을 위하여 고분보존용 공조시스템을 개발할 목적으로 공조시스템을 적용한 고분내부의 실내환경 자료를 확보하고자 공조시스템을 적용한 실물고분을 제작하고, 온 습도 및 공조기의 실내기에 의한 진동수준을 측정하고 검토하였다. 외기의 상대습도가 그다지 높지않은 4월중의 온 습도 측정결과 고분 내부의 온 습도변화는 희망제어조건(온도 $22{\pm}1^{\circ}C$와 상대습도 $55{\pm}3%$)을 다소 초과하는 것으로 나타났다. 운전중 실내기에 의한 진동측정 결과 교통 혹은 기계진동에 의한 문화재 및 기타 진동예민구조물에 대한 스위스 규정보다는 크게 낮은 결과를 얻었으나, 취약건물/문화재 등 주요구조물에 관한 독일규격(DIN4150)에 정하는 무진동 상태를 만족시키지는 못하는 것으로 나타났다.
