産業廃熱の回収を目的とした糖アルコール内包蓄熱マイクロカプセルの開発

抄録

From the viewpoint of effective utilization of unused energy, heat storage technology that can recover, store, and arbitrarily dissipate industrial waste heat generated from factories and power plants has been attracting attention. In this study, we developed thermal storage microcapsules with a core of erythritol, which has a high latent heat capacity among sugar alcohols and undergoes a phase change in the range from 100℃ to 200℃, which accounts for about 70% of industrial waste heat as a heat storage slurry was prepared by dispersing the developed capsules in oil to make them fluid, and thermal characteristics were evaluated by conducting experiments that simulate actual heat storage and heat dissipation. The effects of the decrease in size of the capsules were also investigated.
