Research Abstract

This study is focuses on an emulsion as a new thermal storage material for ice storage. Two types of emulsions were formed using an oil-water mixture with a small amount of additive. A silicone, light and lump oils were used. The water contents of the emulsions were 70, 80 and 90%. The additive was an amino group modified silicone oil. No depression of freezing point was observed for the emulsions because of their hydrophobic properties. In order to determine the structure of the emulsions, their electrical resistances were measured. Moreover, components of the liquids separating from the emulsions were analyzed. The results indicated that one emulsion was a W/O type emulsion, while the other was the O/W type. Finally, adaptability of the two emulsions to ice storage was discussed, it was concluded that a high performance ice slurry could be formed by the W/O type emulsion and the W/O emulsions silicone oil(7:3), light oil(7:3) and lump oil(9:1) exhibited the best ice formation.
However, for the W/O emulsion with over 70% water content the dissolution process of supercooling was very unique. Therefore, the process was investigated from the view of temperature history and dissolution rate of supercooling, and it was found that dissolution rate of supercooling of the emulsion was much slower. Moreover, the time required to dissolve supercooling was measured, varying the composition ratio water to silicone oil. From the experimental results, it was found that longer time to dissolve supercooling in the case of (8:2) with higher viscosity was required compared with the case of (7:3) with lower viscosity. In the case of (9:1) with the highest viscosity ice adhesion to the cooling wall occurred.
