SBIR Phase II: Compact Torus-Shaped Organic Ranking Cycle for Distributed Solar Thermal Power Generation

这个小型企业创新研究(SBIR)第二阶段项目的更广泛的影响/商业潜力是为微型分布式太阳能发电提供有机朗肯循环，并将提供一种比太阳能光伏(PV)更便宜的替代方案，在没有政府激励的情况下，回收期仅为4.5年。利用太阳能热能在住宅层面发电将为太阳能热能行业提供新的鼓励。凭借提供供暖、热水和电力的能力，太阳能热力产品将单手满足家庭的能源需求。大多数人都熟悉传统的观点，即像契约ORC这样的系统的社会影响--降低能源需求和减少温室气体排放。此外，CORC通过改善室内空气质量和提供负担得起的通道，积极影响健康和福祉。许多临床研究将高效系统带来的室内空气质量改善与呼吸和心血管疾病的减少联系起来。结合清洁的室内空气和改善的生活条件对健康的好处，下游对医疗成本的影响将是巨大的。该项目试图解决在没有政府激励的情况下，在住宅和轻型商业层面使用太阳能(光伏和太阳能热能)的可再生能源成本高昂的问题。太阳能可以提供热量和热水，但不能提供电力。光伏发电可以提供电力，但不能提供供暖和热水。紧凑型ORC概念可以同时使用热电联产(CHP)。目前的ORC系统体积庞大，效率低下，最重要的是成本很高。这项研究的目标是将ORC的所有组件结合到一个紧凑、集成、低成本的包中。膨胀机、泵和发电机都将安装在一个公共轴上。蒸发器和冷凝器热交换器将与ORC整体安装，减少效率低下和包装成本。将不会有外部管道将组件连接在一起。其结果将是一个紧凑的装置，在成本和性能上与电网能源具有竞争力。

The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase II project is in Organic Rankine Cycles for distributed solar power generation at micro scale and will offer a cheaper alternative to solar photovoltaic (PV), with a payback period of just 4.5 year without government incentives. The use of solar thermal to generate power at residential level would offer a renewed encouragement to the solar thermal industry. With the ability to provide heat and hot water plus electricity, the solar thermal powered product would fulfill the energy requirements of a home single handedly. Most are familiar with the traditional perspective on the societal impact of a system like the Compact ORC - lower energy demand and reduced greenhouse gas. In addition the CORC positively impacts health and wellbeing by improving indoor air quality and providing affordable access. A number of clinical studies connect improved indoor air quality from efficient systems with a reduction in respiratory and cardiovascular conditions. Combining the health benefits of clean indoor air and improved living conditions, the downstream impact on healthcare cost would be enormous.This project attempts to solve the problem of high cost for renewable energy from solar energy, both PV and solar thermal, at the residential and light commercial level without government incentives. Solar thermal can provide heat and hot water but not electricity. PV can provide electricity but not heat and hot water. The Compact ORC concept can do both with Combined Heat and Power (CHP). Current ORC systems are bulky and inefficient and most importantly high cost. The objective of this research is to combine all of the components of the ORC in one compact, integrated, low cost package. The expander, pump, and generator will all be mounting on a common shaft. The evaporator and condenser heat exchangers will be mounted integral with the ORC reducing inefficiencies and packaging cost. There will be no external piping of components together. The result will be a compact unit that is cost and performance competitive with grid energy.
