PURPOSE:To simplify the system of this device by storing a specific water- insoluble Fluorinert solution in a storage section, keeping this Fluorinert solution at a temperature of 0 deg.C or below, and spraying water in an ice heat storage tank over the Fluorinert solution in the storage section. CONSTITUTION:A water-insoluble Fluorinert solution 12 whose specific gravity is 1.5 times water and whose freezing point is minus 50 deg.C or lower, is stored in a storage section 4 installed to the bottom 2 of an ice heat storage tank 1. This Fluorinert solution 12 is arranged to keep the temperature of minus 0 deg.C or below by a refrigerating cycle. At the same time, the ice heat storage tank 1 and the storage section 4 are connected with each other by way of a pipeline 16 where water 21 in the ice heat storage tank 1 is sprayed over the Fluorinert solution in the storage section 4 so as to separate ice 20. Therefore, the Fluorinert solution 12 and the ice block 20 come into direct contact, and heat-exchanges, thereby improving the efficiency of heat exchange with a heat exchanger 9 by the circulating flow of the Fluorinert solution 12. This construction makes it possible to enhance ice melting performance and simplify the system. |
