(57) [Summary] In a method for treating cold storage water for ice storage, which can store cold heat by cooling to 0 ° C. or lower in a supercooling device, fine crystals of a dissolved solid content due to cooling are precipitated. , Thereby increasing the cold storage efficiency. SOLUTION: Prior to cooling in a subcooling device, aluminum and zinc cations dissolved in cold storage water are substantially removed in a temperature range exceeding 0 ° C. |
