This paper reports 1) thermal analysis of sugar alcohol as candidates of low-temperature (80〜200 ℃) phase change material (PCM), and 2) investigation of phase diagrams of new eutectic sugar alcohol PCMs by calculation and measurement. From the thermal analysis, Threitol, Erythritol, Mannitol and Dulcitol were classified as good PCM candidates. As results of the investigation of phase diagrams, we found eutectic sugar alcohols such as Threitol-Erythritol, Erythritol-Mannitol and Mannitol-Dulcitol. The three eutectic mixtures had new operation temperature compared to single component sugar alcohol PCMs. The calculation values corresponded to those of measurement. The developed PCMs are promising for recovery of low-temperature unused heat such as solar heat.
