An innovative ice energy storage system is being developed leveraging a unique supercooling-based ice production process. During off-peak hours, the proposed system stores the low-cost electric energy in the form of ice; during on-peak hours, the system releases the stored energy to meet extensive home cooling needs.
Ice Bear 20 combines Ice Energy''s patented thermal storage technology with integrated cooling to shift your electricity usage away from high Time of Use (TOU) rate periods. When dispatched to provide cooling, it turns its compressor off and uses the stored ice, frozen during off-hour electricity rates, to cool your home for up to 8 hours
The latent energy storage in the ice serves as a nearly uniform temperature reservoir for heat rejection from a refrigerant that is used to both charge and discharge the ice tank. During ice charging mode, the refrigerant is circulated between the UTSS-internal compressor and the storage tank in a vapor compression cycle using the ice as the
