Experimental studies for freezing phenomena of ethylene glycol solution on a cooled horizontal plate have been performed. As the cooled plate, a glass, an acrylic resin, a polyvinyl chloride, a silicone and a copper plates are used. It is found that the crystal ice formed at some of the cooled plates is removed from the plate surface due to buoyancy force acting the crystal ice. It means that ice formation on a cooled plate without deposit ice layer is possible by the present method. It is shown that the cooled plate surface is undercooled about -2.0 degree below the freezing temperature of the solution during the crystal ice formation and its removal phenomena. The onset conditions for the ice removal phenomena are given by cooling heat flux and by thermal properties of the cooled plate and the solution.
