PCM혼입 시멘트 모르타르 마감재의 열 성능 평가에 관한 실험적 연구

Abstract

PCM is activity tested in passive architecture field but there is any study about finishing materials mixed with PCM28. And, Thermal conductivity measurement needs measuring equipment so it is hard to find the heat conductivity. The purpose of this study is to analyze heating estimation of resin mortar with different proportions of PCM28. At this study, estimated and analyzed Thermal conductivity through heating estimation of finishing materials mixed with PCM28 , and a constant of heating of PCM28 substitute to Fourier's heating law. Then, thermal conductivity of temperature change is interpreted in reverse. Therefore, the more PCM28 is contained, the more temperature gradient is high and estimate the PCM28's heating ability. Through the test, calculated temperature gradient of each model and drew a conclusion thermal conductivity and heating constant using Fourier's heating law and thermal conductivity equation. Then, inverse analysis result, thermal conductivity appeared to similar numerical value and assured the more PCM28 is contained, the less thermal conductivity appeared.
