Abstract
The dynamic-type ice storage system by using super cooling water has been introduced as a large-scale cold heat source for load leveling of building air conditioning. We recognized the potential of this system for process cooling in food industry, that uses only tap water for thermal storage media and stored ice slurry has good characteristics to supply low-temperature water (chilled water). Therefore, this dynamic-type ice storage system was adopted for the chilled water feeder in an actual dairy product plant. This paper describes the calculation results for determining the capacity of refrigerator, the volume of ice storage tank, and the max/min ice packing factor (IPF) in the tank to keep the required temperature of chilled water. Moreover, time histories of IPF and chilled water temperature with heat loads for cooling food process are described, as actual operation results based additional control technologies about full storage detection and supplying tap water into ice storage tank.
