ICE MAKING SYSTEM USING SUBCOOLED WATER AND METHOD FOR MAKING ICE USING SUBCOOLED WATER

摘要

PROBLEM TO BE SOLVED: To improve efficiency in operation while restricting cost in an ice making system using subcooled water.;SOLUTION: An ice making system 100 using subcooling water comprises an ice heat storage tank 10 (heat storage tank) where cold water of water intake and flowing ices are stored, ice nucleation melting heat exchanger 40 (ice nucleation melting device) for heating cold water to melt ice nucleation mixed in cold water, a subcooler 20 (subcooler device) for producing subcooled water from heated cold water and an ice making unit 30 (ice making device) for generating ices from the subcooled water. The ice nucleation melting heat exchanger 40 is controlled to stop heating of cold water before a pre-set time elapses from starting operation of the subcooler 20 and the ice making unit 30 in respect to cold water of which temperature is lower than a temperature that should be reached through heating by the ice nucleation melting heat exchanger 40.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
