We built a mathematics model to analyze the incomplete-frozen conductive plastic ice coil, which can simulate both the processes of ice building and melting.

Among all the ice storage systems, internal-melt ice-on-coil has been widely used because of its high reliability and relatively high charging and discharging rate.

Ice-on-coil storage tank, which consists chiefly of horizontal or spiral coils, is one of important components of direct ice storage system.
