A system with a water-embedded-type ice storage vessel is widely used because of its simple structure and compactness. However, the water-embedded-type ice storage vessel has a disadvantage, that is, the splidification rate is very small. The use of falling water film seems to be one of promising ways for solving this disadvantage. We have found in a previous study that the use of the falling water film is very effective, especially for high initial water temperatures. In the present study, we examined the performance of a falling-water-film-type ice thermal energy storage vessel with practical size, having vertical heat exchanger plates.
