Résumé

Ice making method using evaporation of ethanol solution is useful to ice thermal storage system. In this method, ethanol solution is cooled and ice is produced in it due to the latent heat of evaporation of the ethanol solution under low pressure condition. From our previous experiment, it was found that ethanol concentration of vapour is varied by the condition of ice particles floating on the surface of the solution. It was expected that the sublimation of the ice affects the evaporation phenomenon of ethanol solution. In this study, the effect of sublimation of ice on the evaporation phenomenon of ethanol solution was investigated. In the experiment, the concentration of vapour in ice producing chamber was measured under the various conditions. As a result, it was clarified that the concentration of vapour significantly decreases due to forming of ice layer covering the surface of the solution.
