Abstract
In this study, in order to use waste heat in middle temperature region (100℃〜250℃) from factories, it is investigated about fundamental melting characteristic of erythritol, mannitol, and their mixtures as phase change materials (PCMs), which are applicable for latent heat thermal energy system. The melting point of erythritol and mannitol, melting peak temperature of their mixtures, and latent heat were measured by differential scanning calorimetry (DSC). The melting behavior of these PCMs put in the test tube was observed by the digital camera. The acquired conclusions are; 1) In the DSC measurement, it was found that at mannitol content from 10 to 40mass% and from 70 to 90mass%, these mixtures have one and two melting peak temperature, respectively, and at mannitol content from 50 to 65mass%, it have three melting peak temperature. 2) In fundamental melting behavior of mixtures, it was confirmed that the melting behavior with repeated solidification and melting process does not change, and the density difference of solid phase and liquid phase affects the melting behavior.
