| Outline of Final Research Achievements |
Latent heat storage technology, which utilizes latent heat during solid-liquid phase transition of a phase change material (PCM), can realize a high heat storage capacity and supply heat at a constant temperature. Therefore, this method is suitable for waste heat recovery and solar energy utilization. However a conventional latent heat storage technology cannot realize a long-term heat storage. In addition, an encapsulation technology is needed to avoid a leakage of liquid PCM during heat storage. Therefore, this study proposed third-generation latent heat storage technology utilizing the glass transition to achieve for super long term heat storage and capsule free heat transportation. As results, we investigated a noble glass-transition sugar-alcohol PCM which can be applied the proposed concept. In addition, we designed new heat transportation processes which can achieve the proposed concept.
