If a waste heat of a factory, solar heat etc. can be used effectively, it can contribute to great energy saving and construction of a low carbon society. In this research, we propose the “latent heat thermal energy storage type direct-contact heat exchanger” which combined a latent heat thermal energy storage technology and a direct contact type heat exchange system. We adopted the Mannitol-water mixture as a phase change material. In this heat exchanger, the air is heated by a generation of the air bubble sent in the Mannitol-water mixture. At the same time, the crystal of the Mannitol generated at the air-liquid interface is destroyed by an air bubble and precipitated. Therefore, the heat exchange is performed continuously. This heat exchanger is excellent in cost performance, and can store the energy with high density. In this report, we estimate the possibility of a practical application synthetically.
