Abstract

The granular-ice making method for cool-heat storage has been experimentally investiguted. Granular-ices were formed through injecting water droplets into a low temperature immiscible coolant whose specific gravity is smaller than water. As a low temperature immiscible coolant, kerosine or mixture of kerosine and engine oil has been utilized, where oil concentration was ranged from 0 to 40% in volume. It was found that the granular-ice can be successively produced even at -5°C. Above at -5°C, the ice-bridging phenomenon occurred for any concentration measured. Optimum conditions for succesive production of granular-ice were obtained as follows. 1) circulation of the mixture of kerosine and engine oil, and 2) no circulation of kerosine only. The effect of coolant temperature and viscosity on the successive production of granular-ices were discussed.
