Summary

A dynamic-type of ice-making cold thermal energy storage system using water-oil emulsion with a silane-coupler agent was investigated. In order to establish a suitable method by which slurry ice can be formed continuously in a tube without ice adhesion to the cooling wall, the effects of the tube materials of the heat exchanger, heat exchanger types and phase change materials on the ice formation process were investigated. Experiments of ice formation were operated under various cooling conditions of flow rate of the mixture and temperature of cooling brine. It was found that using a fluoroplastic tube prevented ice from adhering to the tube under a wide range of the cooling conditions. By making the thickness of the tube thinner and increasing the heat transfer coefficient on the outside of the tube, the performance of the heat exchanger in ice-making was improved. The range of suitable cooling conditions obtained using the water-oil emulsion as a phase-change material was wider than that obtained using ethylene glycol aqueous solution.
