This study is focused on an emulsion as a new thermal storage material for ice storage. Two types of emulsions are made of oil-water mixture with a little additive. Oils used are silicone, light and lump oils. Water contents of emulsions are 70,80 and 90 %. The additive is amino group modified silicone oil, and there is no depression of freezing point for the emulsions because of its hydrophobic property. In order to know structures of emulsions, those electric resistances were measured. And components of liquids separating from emulsions were investigated. From above results, it was found that one was W/O type and the other was O/W type. And then, adaptability of two emulsions to the ice storage was discussed, and then, it was found that a high performance ice slurry could be formed by the W/O type emulsion.
