  • Patent number: 10955151
    Abstract: A system and method for estimating the state of charge, i.e., the amount of cooling remaining, in a latent heat thermal storage module of a local environmental control system. The local environmental control system stores cooling energy at night by freezing a latent heat phase change material (PCM), and then releasing the stored cooling energy by removing heat from room air flowing through the PCM during the day. Differential temperature sensors are used measure the air temperature drop across the latent thermals storage unit and the fan voltage, which is directly related to fan air flow rate, is sampled. A controller is programmed to determine the charging state from these measurements.

  • Patent number: 9580310
    Abstract: A method and apparatus for producing hydrogen and a passivating oxide using water splitting techniques is disclosed. The apparatus comprises a container filled with a passivating-oxide preventing agent that is substantially inert to water in an effective amount to prevent passivation of a solid-state material during oxidation and a conduit for inserting a solid-state material into the passivating-oxide preventing agent in which the solid-state material is submerged in the passivating-oxide preventing agent without being in direct contact with water. The solid-state material is capable of dissolving in the passivating-oxide preventing agent and reacting with the water. Thus, the method provides continuous dissolution of the solid-state material into the passivating-oxide preventing agent and its alloys in the presence of excess water at or near room temperature to enable continuous generation of hydrogen, passivating oxide and heat.

  • Patent number: 9493695
    Abstract: Storage systems based on latent heat storage have high-energy storage density, which reduces the footprint of the system and the cost. However, phase change materials (PCMs), such as NaNO3, NaCl, KNO3, have very low thermal conductivities. To enhave the storage of PCMs, macroencapsulation of PCMs was performed using a metal oxide, such as SiO2 or a graphene-SiO2, over polyimide-coated or nickel-embedded, polyimide-coated pellets The macro encapsulation provides a self-supporting structure, enhances the heat transfer rate, and provides a cost effective and reliable solution for thermal energy storage for use in solar thermal power plants. NaNO3 was selected for thermal storage in a temperature range of 300° C. to 500° C. The PCM was encapsulated in a metal oxide cell using self-assembly reactions, hydrolysis, and simultaneous chemical oxidation at various temperatures.

  • Patent number: 9487690
    Abstract: The present invention relates to an anisotropic heat conductive composition including flake graphite particles and a resin composition for the particles to be dispersed therein. When the particles have a basal plane, a maximum diameter a in a direction of the basal plane, and a thickness c perpendicular to the basal plane, a/c is 30 or more on average, and a content of the particles is more than 40 mass % and 90 mass % or less. Since the composition includes the particles having a particular shape, when it is formed into a sheet, an anisotropic heat conductive path can be efficiently created therein. Thus, the present invention can provide a molded product in sheet form, suited to have therein a heat conductive path capable of dispersing heat from a high temperature region to a low temperature region.

  • Patent number: 9482461
    Abstract: The heat exchanger is adapted for cooling a coolant (e.g., water), used to cool a device or an area (e.g., building interior), such as during periods of peak energy cost and usage, to save energy and energy costs. The heat exchanger includes a coolant storage tank with one or more refrigerant circulators in contact with the floor of the tank. The circulators use a refrigerant having a freezing temperature colder than the coolant, with coolant on the floor of the tank forming a layer of ice thereon. A rotary scraper extends up through the tank floor from each circulator, with the scrapers operating to remove the thin layer of ice from the floor as the ice forms. The resulting ice chips are relatively small and thin, thus having a relatively large surface area for their volume in order to maximize melting and rapid cooling of the coolant.
