| Abstract |
Techniques using thermal storage materials, one of the new techniques of energy conservation, have been used variously and have contributed to save the energy. The latent heat storage techniques are widely used to utilize thermal energy in various fields because there is much more heat saving compared to the sensible heat. Phase Change Material(PCM), one of the materials used in latent heat storage techniques, is very efficient ways to store heat energy using thermal storage by latent heat. PCM is a material whose phase changes at a certain temperature with heat storage and release in the form of latent heat, and many studies have conducted by utilizing this to reduce energy consumption. In this study, the thermal analysis of the gypsum board improved thermal performance, that was impregnated with noctadecane which is a paraffinic PCM was produced, and thermal performance and strength of that were analyzed. As a result of the analysis, the larger the mixing ratio of porous materials impregnated with PCM, the higher the thermal conductivity was high. This can be applied to save the building energy and enhance the comfort of occupants when the heat storage gypsum board is used as a functional building material. |
