Research on the Thermal Storage Performance of Solid-Solid Phase-Change Material Used in the Wall

Solid-solid phase change material can increase the thermal storage capacity of the wall, decrease the indoor temperature fluctuation and building energy consumption when it was used in the phase change material (PCM) wall. This paper investigated experimentally the phase change temperature and latent heat of polyalcohols binary system with different component, and analyzed the feasibility of phase change wall. The results show that binary systems have suitable phase change temperature and bigger phase change latent. They are ideal phase change materials used in the wall.
