DYNAMIC TYPE ICE STORAGE SYSTEM AND ITS DOUBLE PIPE TYPE HEAT-EXCHANGER AND SUPERCOOLING RELEASE PIPE

摘要

PROBLEM TO BE SOLVED: To prevent suspension of ice making operation due to freezing and to perform operation at the proper degree of supercooling in a continuous and high ice making capacity state. SOLUTION: The temperature of cold water at the outlet of a heat-exchanger 2 of a supercooler 1 is detected and a flow rate of a water pump 4 to return cold water 3a to a supercooler 1 to an ice storage tank 3 is controlled according to the temperature of cold water. Further, the heat-exchanger 2 is a double pipe type heat-exchanger, and a supercooling release pipe 10 in which a floating body 11 is floated is situated below an outlet for supercooling cold water.
