Title:
ICE STORAGE DEVICE
Document Type and Number:
Japanese Patent JP3854675
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent freezing in a cold water flow passage in an ice storage device making use of the heat source of an existing ice storage device by providing a preheater to heat the cold water flowing from an ice storage tank to a supercooler wt the sensible heat of the liquid refrigerant in a refrigerating machine.
SOLUTION: The cold water of 0°C stored in an ice thermal storage tank 9 is supplied to a preheater 19 through a cold water circulation pump 17. The cold water heater to 0.5°C by the preheater 19 is supplied to a supercooler 5. In the supercooler 5, the cold water of 0.5°C is cooled in the supercooled condition of -2°C by the brine of -6°C. After the temperature rises to -3°C, the brine is carried to an evaporator 21 by a brine circulation pump 30, and cooled to -6°C by the evaporator 21, and again, supplied to the supercooler 5. The supercooled water generated in the supercooler 5 is released from its supercooled condition in a supercooling relieving tank 7 to generate the sherbet- like ice water. The sherbet-like ice water is stored in the ice storage tank 9 through an ice water flow passage 64.
