- Description
- Opportunity: Lawrence Livermore National Laboratory (LLNL), operated by the Lawrence Livermore National Security (LLNS), LLC under contract no. DE-AC52-07NA27344 (Contract 44) with the U.S. Department of Energy (DOE), is offering the opportunity to enter into a collaboration to further develop and commercialize its passive cooling technology using infrared transparent composite foams. Background: Surfaces that face towards the sky experience thermal radiative heat loss. The radiation can then escape to space because the atmosphere is transparent to wavelengths between 8 and 13 um which encompasses the peak of thermal radiation at room temperature. By using passive cooling materials, the underlying sky-facing surface can be cooled to sub-ambient temperatures. One promising material is aerogel made of polyethylene (PE).� However, the polymeric material easily degrades in sunlight and is expensive. When PE aerogels are used, the IR transmission is subsequently reduced within just a few days and the PE films only last weeks to months before falling apart.� LLNL researchers have developed an approach to efficient cool surfaces by designing an inexpensive material/device combination which allows for heat loss into space and prevents heating from sunlight and ambient surroundings. Description: LLNL researchers have developed a passive cooling system which is (1) infrared transparent in the 8-13 um wavelength range, (2) optically reflective to reduce surface heating from sunlight, and (3) thermally insulating to avoid heating from surrounding air. The device uses a material composite that provides cooling via maintaining a temperature difference between a surface and ambient air. The LLNL technology consists of: A foam or aerogel made from an inexpensive IR transparent material, such as common table salt (NaCl) contains a certain size distribution and porosity to add optical reflectance and maintain strength, while continuing to provide high thermal resistance for insulating power. that can be coated with a hydrophobic coating to stop moisture absorption and other deleterious effects of outdoor weather An optomechanical frame that serves to concentrate emitted radiation to the most transparent part sky (near vertical) and improve the net cooling power as a mechanical support to the foam. A UV-stabilized, IR transparent plastic film can encapsulate the whole device as a moisture and water barrier. Advantages/Benefits:� Can be used to cool virtually any surface. Uses low cost, earth abundant materials, such as NaCl. Flexible design architecture for the optomechanical frame, which can be customized; modules can be tailored for targeted use cases. Potential Applications:� Can be used for: Cooling buildings or vehicles directly Recycle evaporated process water (cooling towers) and condense potable water from the air in arid areas Electricity-free air conditioning, remote refrigeration, potable water Development Status:� Current stage of technology development:� TRL 4 LLNL has patent protection and copyrights on this invention. U.S. Patent Application No. 2023/0106815 Infrared Transparent Foam Composite For Deep Subambient Cooling Of Virtually Any Surface published 4/6/2023 LLNL is seeking industry partners with a demonstrated ability to bring such inventions to the market. Moving critical technology beyond the Laboratory to the commercial world helps our licensees gain a competitive edge in the marketplace. All licensing activities are conducted under policies relating to the strict nondisclosure of company proprietary information.� Please visit the IPO website at https://ipo.llnl.gov/resources for more information on working with LLNL and the industrial partnering and technology transfer process. Note:� THIS IS NOT A PROCUREMENT.� Companies interested in commercializing LLNL's Infrared transparent composite foams as passive cooling technology should provide an electronic OR written statement of interest, which includes the following: Company Name and address. The name, address, and telephone number of a point of contact. A description of corporate expertise and/or facilities relevant to commercializing this technology. Please provide a complete electronic OR written statement to ensure consideration of your interest in LLNL's Infrared transparent composite foams as passive cooling technology.
