Summary

A system with ice storage tank is widely used because of its simple structure and compactness. However, this ice storage tank has a disadvantage, that is, the melting rate is very small. The use of falling water film seems to be one of promising ways for solving this disadvantage. The authors 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, they examined the melting performance of a falling-water-film ice storage tank with practical size, having vertical heat exchange plates. The results obtained are as follows: the quantity of melting ice increases with increase of the water film flow rate, the melting rate decreases with time because ice surface area decreases with time gradually, the heat transfer coefficient of melting increases with increase of the water film flow rate, and the melting rate increases with increase of the water-spray temperature.
