Abstract

Researches have been carried out on the application of phase change materials(PCMs) to reduce building energy. In this study, Mixed Shape-stabilized PCMs(Mixed SSPCMs) were prepared using fatty acid ester PCM and paraffin PCM, which have higher economic and thermal performance than other PCMs respectively, and thermal performance was evaluated. Through chemical binding analysis by FT-IR, it was confirmed that there was no chemical bond between n-hexadecane and coconut oil, which are the PCMs used in the experiment. Also, DSC analysis showed that the Mixed SSPCMs showed higher storage performance than the SSPCMs single PCM was impregnated in the previous study. In order to improve the low thermal conductivity of PCM, xGnP, which is one type of modified carbon, was used and the improvement of thermal conductivity of Mixed SSPCMs was confirmed through the TCi.
