Résumé

The authors developed a new dynamic type ice making system for thermal storage. A phase change material for the system was emulsion consisted of aqueous solution and silicon-oil. The solution was a mixture of gamma-aminopropyl-triethoxy-silane and tap water. The emulsion reduces the risk of adhesions of ice on a cooling wall in an ice making process, even though there is a lot of ice near the wall. An ice making chamber of the system consisted of vertical stainless-steel pipe. Agitated by rotor blades equipped in the tube, the emulsion in the tube was cooled by brine flowing outside the tube. Mass of ice increased with cooling of the emulsion. Condition was examined with a change of cooling rate when ice adhesion occurred. By cycling the operation of making and discharging of ice, the authors confirmed that the system was able to make ice continuously. Shapes of the ice particles made by the system were roughly spherical and sizes of those depended on cooling rate. They investigated the relationship between the ice particle size and cooling rate.
