Before constructing ice thermal storage systems for air conditioning in buildings and works, the ice-melting characteristics in the storage tank must be better understood. Accordingly, the present study evaluated the ice-melting characteristics of harvested ice from an ice thermal storage system. That is, the effects of the inlet-water release position in the tanks, the inlet-water spraying method, and the water-replacement time (in the case of three tank sizes) on the temperature of the outlet water from the system were determined. It was consequently found that the average modified Stanton number can be used to evaluate the ice-melting characteristics effectively in an actual-size tank.
