  • Direct-contact heat exchange thermal energy storage system
    Patent number: 12313346
    Abstract: A thermal energy storage system having a thermal storage tank configured to hold a thermal storage media and a working fluid, an inlet in fluid communication with a liquid distributor disposed at the bottom of the thermal storage tank configured to introduce the working fluid into the thermal storage tank, a skimmer configured to direct the working fluid accumulated at the top of the thermal storage tank toward an outlet, a charging/discharging section fluidly connected to the thermal storage tank via the inlet and the outlet.

  • Heat exchange system for freezing a phase change material and methods thereof
    Patent number: 12000659
    Abstract: A heat exchange system including a tank, a phase change material (PCM) held in the tank, an immiscible liquid layer held in the tank, a heat exchanger located within the immiscible liquid layer, and a distributor located above the heat exchanger. The immiscible liquid layer has a density lower than a density of the PCM and is located above the PCM. The distributor is configured to introduce a plurality of PCM droplets into the immiscible liquid layer and above the heat exchanger.

  • HEAT EXCHANGE SYSTEM FOR FREEZING, TRANSFERRING, STORING, AND UTILIZING PHASE CHANGE MATERIAL AND APPLICATION OF THAT SYSTEM TO A THERMAL ENERGY STORAGE SYSTEM
    Publication number: 20230266079
    Abstract: A heat exchange system including an icephobic heat exchanger (IHEX) tank, a phase change material (PCM) held in the IHEX tank, an immiscible liquid layer held in the IHEX tank, a heat exchanger located within the immiscible liquid layer, and a distributor located above the heat exchanger configured to introduce a plurality of liquid PCM droplets into the immiscible liquid layer. The system further includes a transfer mechanism configured to remove PCM from the IHEX tank, and an external storage tank configured to receive the removed PCM. The immiscible liquid layer has a density lower than a density of both the solid and liquid PCM, and the PCM and the immiscible liquid layer meeting at a PCM-immiscible liquid interface.
