126400000 | HEAT ACCUMULATOR STRUCTURES | 9 |
20080210218 | Dynamic heat accumulator and method for storing heat - A heat accumulator has a heat accumulator structure with at least two accumulator elements through which a medium flows for charging and that thus each forms a hot end and a cold end by temperature layering and having a medium rinse device. In a rinse operation the heat accumulator produces at least one cold medium rinse flow and introduces it into the cold end of at least one of the accumulator elements. The hot medium rinse flow exiting from the hot end of the accumulator element enters the hot end that is in the charged state via at least one rinse path. | 09-04-2008 |
20090007900 | METHOD FOR OPERATING AN ACTIVE THERMAL ENERGY STORAGE SYSTEM - An active thermal energy storage system is disclosed which uses an energy storage material that is stable at atmospheric pressure and temperature and has a melting point higher than 32 degrees F. This energy storage material is held within a storage tank and used as an energy storage source, from which a heat transfer system (e.g., a heat pump) can draw to provide heating of residential or commercial buildings and associated hot water. The energy storage material may also accept waste heat from a conventional air conditioning loop, and may store such heat until needed. The system may be supplemented by a solar panel system that can be used to collect energy during daylight hours, storing the collected energy in the energy storage material. The stored energy may then be used during the evening hours to heat recirculation air for a building in which the system is installed. | 01-08-2009 |
20110017196 | THERMAL ENERGY STORAGE VESSEL, SYSTEMS, AND METHODS - A containment vessel for a thermal energy storage system comprising a bottom wall joined to a surrounding containment side wall, and a liner comprising a liner bottom disposed upon the bottom wall of the vessel, the liner bottom having an outer perimeter and comprising an array of plates, each of the plates joined at a portion of its perimeter to a portion of the perimeter of an adjacent plate by a flexible joint; and a liner side wall joined to the outer perimeter of the liner bottom and disposed within the containment side wall. A thermal energy storage system comprising the containment vessel and an array of heat exchangers is also disclosed. The heat exchangers are disposed in the vessel, and are each supported by a support frame joined to one of the plates of the array of plates of the liner. | 01-27-2011 |
20110168159 | DUAL THERMAL ENERGY STORAGE TANK - A thermocline storage tank is presented, which includes a barrier member that floats between the two fluids stored at different temperatures, physically separating and insulating them. The floating barrier includes a number of design features that broaden its application scope, enabling it for use in fields like thermal storage systems of solar power plants. | 07-14-2011 |
20120037148 | ARTICLES AND DEVICES FOR THERMAL ENERGY STORAGE AND METHODS THEREOF - The present invention relates to articles and heat storage devices for storage of thermal energy. The articles include a metal base sheet and a metal cover sheet, wherein the metal base sheet and the metal cover sheet are sealingly joined to form one or more sealed spaces. The articles include a thermal energy storage material that is contained within the sealed spaces. The sealed spaces preferably are substantially free of water or includes liquid water at a concentration of about 1 percent by volume or less at a temperature of about 25° C., based on the total volume of the sealed spaces. The articles include one or more of the following features: a) the pressure in a sealed space is about 700 Torr or less, when the temperature of the thermal energy storage material is about 25° C.; b) the metal cover sheet includes one or more stiffening features, wherein the stiffening features include indents into the sealed space, protrusions out of the sealed space, or both, that are sufficient in size and number to reduce the maximum von Mises stress in the cover sheet during thermal cycling; c) the metal cover sheet and/or the metal base sheet includes one or more volume expansion features; or d) the metal cover sheet has a thickness, t | 02-16-2012 |
20120167870 | SYSTEM FOR STORAGE AND TRANSFER OF HEAT ENERGY - The present invention relates to a system of transfer and storage of thermal energy to and from the surrounding environment. In particular, this invention relates to a thermo-well ( | 07-05-2012 |
20120240919 | LATENT HEAT STORAGE MATERIAL WITH PHASE CHANGE MATERIAL IMPREGNATED IN A GRAPHITE MATRIX, AND PRODUCTION METHOD - A latent heat storage material is formed of at least two plies of a compressible graphitic material in which graphite wafers are arranged substantially in layer planes lying one on the other and which is infiltrated with at least one phase change material. The surface of each ply is provided with a structuring reaching the outsides of the graphite material bundle. The evacuation and infiltration travel lengths in the layer planes, due to the structuring, amounts to a maximum of 200 mm. | 09-27-2012 |
20120312292 | DEVICE AND SYSTEM FOR THE INTERMEDIATE STORAGE OF THERMAL ENERGY - A device for the intermediate storage of thermal energy and to a system comprising a plurality of such devices is provided. The device has a solids store and a pipe system, which is formed of individual pipes and runs through the solids store and through which an energy carrier medium flows. In order to be able to quickly and uniformly charge the solids store with thermal energy or discharge thermal energy therefrom, heat conducting elements are provided, each forming heat transmission regions with the individual pipes and each extending into the regions of the solids store that are free of individual pipes. The heat conducting elements also have a higher heat conductivity than the solids store. | 12-13-2012 |
