A STUDY ON THE THERMAL AND OPTICAL BEHAVIOR OF THE WINDOW APPLYING THE GELLED PHASE CHANGE MATERIAL

Abstract

The purpose of this study is to clarify the effect of energy saving and environmental improvement of the window applying the gelled PCM with elastomer. The gelled PCM is possible to solve a technical problem because of that characteristic properties. According to the experimental results, the light transmittance in the solid and the liquid phase shows 0.1 and 0.6[-]. The heat transmission coefficient of this window is about 6[W/m²/K] at the minimum. When the PCM window installed experimental housing, temperature fluctuation was reduced about 5[K] and the average reduction rate of energy consumption is 13.4[%], and 28.7[%] in maximum.
