A method to making ice slurry is one of key technology for cold-energy storage system. This study has been performed to study the use of ultrasonic vibration to remove the crystal-ice layer formed on the cooled plate continuously. In the experiments, ethylene glycol solution was used. It is found that the ice layer is removed at the region that amplitude of displacement caused by ultrasonic wave is large, but it accumulates at the region that amplitude is small. The ice making process is calssified into four characteristic patterns; stable ice making, remove-deposition type ice making, no-remove type ice making, and no ice making. The characteristics of ice making were discussed with the temperature of cooled plate and the solute concentration.
