IPC: F25C5/06
Filed: 1989-12-14
Abstract: PURPOSE:To utilize the almost whole volume of a liquid reservoir to store ice by a method wherein ice formed on the surface of a heat exchanger is removed from the surface of the heat exchanger in turn and let the ice float up. CONSTITUTION:When ice adequately grows, a cooling plate 3 is swung and deformed by a mechanical driving device. By this action, the ice 5 formed on the cooling plate 3 is broken into pieces of ice 6 and float up toward the top layer of heat storage liquid 2. As a result, the surface of the cooling plate 3 comes in contact with the fresh heat storage liquid and the ice making process efficiently continues. Thereby, the whole volume of a heat storage tank can be filled full with the ice pieces 6 finally, and a larger amount of ice can be stored compared with a method wherein coils are arranged throughout a heat storage tank.
