PROBLEM TO BE SOLVED: To provide ice thermal storage equipment capable of forming a proper ice accumulation layer in a thermal storage tank. SOLUTION: In constituting an ice thermal storage equipment for storing cold heat in the thermal storage tank 1 by forming the ice accumulation layer A floating in the stored water C in the thermal storage tank 1, by supplying ice particles (a) made by ice making devices X, 3 from an ice supply opening 3c into the stored cold water C in the thermal storage tank 1 in accompany with supply of the stored cold water C in the thermal storage tank 1 as ice making raw water, from a lower portion of the tank to the ice making devices X, 3, the ice supply opening 3c is positioned at an upper portion in the stored cold water C in the thermal storage tank 1 and the ice accumulation layer A is formed at its upper portion in an initial period of the formation of the ice accumulation layer A, and then the ice supply opening 3c is gradually moved downward in accompany with the growing of the ice accumulation layer A to keep a position of the ice supply opening 3c near the lower portion of the ice accumulation layer A.
