Title:
DEVICE FOR CALCULATING PRODUCTION VOLUME OF SALINE WATER/ICE AND/OR WATER/ICE, METHOD OF CALCULATING PRODUCTION VOLUME OF SALINE WATER/ICE AND/OR WATER/ICE, AND DEVICE FOR PRODUCING SALINE WATER/ICE AND/OR WATER/ICE PROVIDED WITH DEVICE FOR CALCULATING PRODUCTION VOLUME OF SALINE WATER/ICE AND/OR WATER/ICE
Document Type and Number:
WIPO Patent Application WO/2023/026539
Kind Code:
A1
Abstract:
The present invention is a device for calculating the production volume of immersion storage-use saline water/ice and/or water/ice, the foregoing comprising saline water and saline ice or water and ice which are to be used for refrigeration storage of food products. The device is provided with: a total exothermic quantity calculation unit for calculating a total exothermic quantity of the food products, which is the total exothermic quantity of the food products as found from the specific heat in the food products, the quantity of the food products, the initial temperature of the food products, and the temperature required for storage; a water/ice total endothermic quantity calculation unit for calculating a total endothermic quantity of ice, which is the total endothermic quantity of ice as found from the amount of the saline water/ice or water/ice and the ice packing factor (IPF) of the saline water/ice or water/ice; a water/ice quantity calculation unit for calculating the quantity of ice of the saline water/ice or water/ice at the start of storage as found from the total exothermic quantity and the total endothermic quantity; and a storage temperature/storage duration calculation unit for calculating the change over time in the ice quantity for the saline water/ice or water/ice from the ice quantity as well as from a gradual heat dissipation quantity calculation model using a storage container heat dissipation quantity parameter as an overall heat transfer coefficient. This configuration enables proper calculation of production volumes for saline water/ice and/or water/ice in a short duration of time.
