The broader impact/commercial potential of this Small Business Innovation Research (SBIR) project addresses the immediate need to develop advanced air conditioning technology that increases energy efficiency and will have a significant and positive impact on reducing Greenhouse Gas (GHG) Emissions. As Room Air Conditioning (RAC) demand increases by an estimated 5x over the next 30 years, it is crucial that newly established scientific and technological approaches be developed which lessen the requirement of 'peaker' power plants to supply electricity for their operation. Nativus is engineering an energy-efficient 12,000 BTU Room Air Conditioner (RAC) for residential and light-commercial consumers, capable of cooling 500 ft2. Through a complete architectural redesign, our proprietary technology offers customers a solution to their air conditioning needs which is cheaper to operate, quieter, filters the air, and is easier to install than currently available commercial offerings.This SBIR Phase I project proposes to develop a novel, rotating air conditioning design which combines the main components of an air conditioner into a single, packaged device to drastically increase air conditioner performance. The roughly one billion air conditioners in operation globally operate at 5-10% of their theoretical ultimate Carnot efficiency, as industry focuses on "first-cost" and has not demonstrated meaningful, radical improvements since the inception of the air conditioner. The current state-of-the-art technology in the HVAC industry is based upon the 'fan plus finned-tube' (FPFT) Heat Exchanger in which a fan blows air across either hot or cold heat exchanger fins. This architecture results in the formation of an insulative 'boundary layer', severely degrading heat exchanger performance. Through the use of one high-efficiency motor, instead of two or three motors commonly found on state-of-the-art technology, our proprietary design rotationally-shears the boundary layer from the surface of the heat exchanger, thereby increasing efficiency while decreasing power consumption. Our research objectives include air conditioner component and system-level validation, supported by three milestones which include Nationally Recognized Testing Laboratory (NRTL) performance validation, system reliability through prototype testing, and economic analysis. The tasks involved in our project include design, manufacture, assemble, and testing of a complete system.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.

这项小型企业创新研究（SBIR）项目的广泛影响/商业潜力解决了开发先进空调技术的迫切需求，该技术可以提高能源效率，并对减少温室气体（GHG）排放产生重大而积极的影响。由于室内空调（RAC）的需求在未来30年预计将增加5倍，因此开发新的科学和技术方法以减少“峰值”发电厂为其运行提供电力的需求至关重要。natvus正在为住宅和轻型商业用户设计一款节能的12,000 BTU房间空调（RAC），能够冷却500平方英尺。通过完整的架构重新设计，我们的专有技术为客户提供了一个解决方案，以满足他们的空调需求，更便宜的操作，更安静，过滤空气，比目前可用的商业产品更容易安装。这个SBIR一期项目建议开发一种新颖的旋转空调设计，将空调的主要部件组合成一个单一的包装设备，以大幅提高空调的性能。全球大约有10亿台空调在运行，其理论最终卡诺效率只有5-10%，因为行业关注的是“首次成本”，自空调问世以来，还没有表现出有意义的、根本性的改进。目前暖通空调行业最先进的技术是基于“风扇加翅片管”（FPFT）热交换器，其中风扇将空气吹过热或冷热交换器的翅片。这种结构导致隔热“边界层”的形成，严重降低了热交换器的性能。通过使用一个高效电机，而不是在最先进的技术中常见的两个或三个电机，我们的专有设计旋转剪切热交换器表面的附面层，从而提高效率，同时降低功耗。我们的研究目标包括空调部件和系统级验证，并由三个里程碑支持，包括国家认可的测试实验室（NRTL）性能验证，通过原型测试的系统可靠性和经济分析。我们项目涉及的任务包括设计、制造、组装和测试一个完整的系统。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。
