SBIR Phase I: Hybrid Solar Panel for Radiative Thermal Exchange

这项小企业创新研究（SBIR）项目的更广泛影响/商业潜力是促进可再生太阳能供暖和制冷的国内市场。世界上超过50%的能源为住宅、商业和工业应用提供供暖和制冷，其中大部分来自化石燃料的燃烧。这项工作的基础是一种低成本的面板解决方案，用于可再生太阳能热收集，包括夜间冷却组件。对于多户住宅来说，这种独特的方法将有可能满足60%以上的热水、空间供暖和空间制冷需求。该解决方案可以解决高达4,400 TBtu的需求，创造340亿美元的机会，同时减少电力消耗和制冷剂需求。这个小企业创新研究（SBIR）第一阶段项目将建立在成熟的太阳能热架构上。目前的太阳能热解决方案将被修改，以增强其固有的辐射冷却能力。这项工作将侧重于确定和指定新型聚合物和含氟聚合物薄膜，其发射率和透射性能可以得到提高。光学表征后，感兴趣的样品膜将按比例制作，以包含在全尺寸测试板中，使用内部太阳能模拟器进行评估，并最终通过现场测试。这项工作还需要修改面板结构，以减少从环境中吸收的热量。其结果将是太阳能热产品家族的延伸。理论上可以达到100 W/m2的冷却速率。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

The broader impact/commercial potential of this Small Business Innovation Research (SBIR) project is to catalyze the domestic market for renewable solar heating and cooling. Over 50% of the world's energy provides heating and cooling for residential, commercial and industrial applications, most of which is generated from the combustion of fossil fuels. The basis for this work is a low-cost panelized solution for renewable solar heat collection incorporating a cooling component at night. For multi-family homes, this singular approach will make it possible to satisfy more than 60% of the hot water, space heating, and space cooling demands. This solution could address up to 4,400 TBtu of this demand, a $34 B opportunity, while reducing electricity consumption and demand for refrigerants. This Small Business Innovation Research (SBIR) Phase I project will build on the proven solar heat architecture. The current solar heat only solution will be modified to enhance its inherent radiative cooling capability. The effort will focus on identifying and specifying novel polymer and fluoropolymer films whose emittance and transmission properties can be enhanced. After optical characterization, sample films of interest will be fabricated at scale for inclusion into a full-sized test panel to be evaluated using an in-house solar simulator and ultimately via field testing. The work will also require modifications to the panel architecture to decrease the heat absorbed from the environment. The result will be an extension of the solar heat product family. Cooling rates as high as 100 W/m2 are theoretically possible.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
