A dynamic-type of ice-making cold thermal energy storage system was investigated. Slurry ice was formed continuously by cooling water-silicone oil emulsion with silane-coupler agent in a heat exchanger. Experiments were carried out in order to clarify the conditions for continuous ice formation without choking in the heat exchanger. It was found that the choking occurred when the ice content of the emulsion flowing into the heat exchanger became lager than a critical value or when the oil content of the emulsion became less than a critical value. It was found that the freezing point of the emulsion rose gradually by aeration. Additionally, as the freezing point rose, the range of condition for the continuous ice formation became narrower. The ice formation system was improved as much as possible to avoid the exposure of the emulsion to air. It was confirmed that the improved system could hold a low freezing point.
