This PFI: AIR Technology Translation project focuses on translating previous NSF discoveries of superwicking surfaces to the production of heat exchangers, the most critical component in evaporative coolers, and subsequently creating Super-Wicking Efficient Evaporative Technology based Air Conditioners (SWEET-ACs). The SWEET-AC concept is important because it will deliver an energy efficient and environmentally friendly cooling technology. Continuous increases in median global temperatures, hikes in energy prices, widespread water shortages, and climate change issues all will lead to a demand for higher energy efficiency products. Compared to conventional vapor compressor-based air conditioners, the SWEET-ACs will have an enhanced cooling efficiency while producing a minimal carbon footprint in order to meet market demands and societal needs. This project addresses the following technology gaps as it translates from research discovery toward commercial application. Conventional vapor compression air-conditioning systems consume a large amount of electrical energy and have a detrimental impact on the environment. Direct and indirect evaporative cooling technologies can significantly reduce energy consumption compared to the conventional ACs. However, current evaporative coolers are far from reaching their potential in energy efficiency and the hurdle is the lack of optimized heat exchangers. This project will directly address this key issue by developing a scalable and high performance heat exchanger material for evaporative coolers. In contrast to conventional evaporation materials, the proposed superwicking surfaces do not require water pump to constantly wet the heat exchangers. They will have a water contact angle of 5 degrees, a surface saturation of 90%, a minimum wicking speed of 1 cm/sec, and a minimum unit area cooling power of 0.2 W/cm2 for an air velocity of 4 m/sec at 40 C. In addition, this AIR: TT project will train graduate and undergraduate students, and postdoctoral researchers with commercialization and entrepreneurship skills in additional to their research. The project will engage air conditioner companies to guide the team in industrial requirements and commercialization aspects in this technology translation effort from research discovery toward commercial reality.

该PFI：空气技术翻译项目着重于将超级挥杆表面的先前发现转化为热交换器的生产，这是蒸发冷却器中最关键的组成部分，然后创建了超级挑选的高效蒸发蒸发技术基于技术的空调（Sweet-Acs）。 Sweet-AC概念很重要，因为它将提供节能且环保的冷却技术。全球温度中位数的持续提高，能源价格上涨，广泛的水短缺以及气候变化问题都将导致对更高能源效率产品的需求。与常规的蒸气压缩机空调相比，Sweet-ACS的冷却效率将提高，同时产生最少的碳足迹，以满足市场需求和社会需求。该项目解决了以下技术差距，因为它从研究发现转化为商业应用程序。常规的蒸气压缩空调系统消耗大量电能，并对环境产生不利影响。与常规AC相比，直接和间接的蒸发冷却技术可以显着降低能耗。但是，当前的蒸发冷却器远未达到能源效率的潜力，障碍是缺乏优化的热交换器。该项目将通过为蒸发冷却器开发可扩展和高性能热交换器材料来直接解决这一关键问题。与传统的蒸发材料相反，提议的超级焊接表面不需要水泵不断弄湿热交换器。 They will have a water contact angle of 5 degrees, a surface saturation of 90%, a minimum wicking speed of 1 cm/sec, and a minimum unit area cooling power of 0.2 W/cm2 for an air velocity of 4 m/sec at 40 C. In addition, this AIR: TT project will tr​​ain graduate and undergraduate students, and postdoctoral researchers with commercialization and entrepreneurship skills in additional to their research.该项目将吸引空调公司，以指导团队从研究发现到商业现实的技术翻译工作中的工业需求和商业化方面。
