Résumé

In this study, an original method for production of ice slurry from ethanol solution without using a refrigerator is proposed. As was introduced in the first report, this system has advantages compared with similar existing systems using materials other than ethanol solution. In this paper, the process of producing ice slurry using this method was observed, and the relationship between ethanol concentration of the solution and that of the vapour, which evaporated from the ice-solution mixture, was measured. It was found that the ethanol concentration of vapour was lower than that in the condition that did not produce ice. The composition of vapour was found to be affected by the sublimation of the ice produced. Finally, the COP of this system was estimated and the effect of sublimation of ice was investigated.
