The broader impact/commercial potential of this Small Business Innovation Research (SBIR) project is that it will significantly lower the initial cost of residential and commercial ground-source heat pump (GSHP) systems, while expanding the existing market through broadening GSHP applicability. This project will demonstrate the feasibility and performance under real-world conditions of a novel in-ground heat exchanger that is both inexpensive and easy to install, even on space-constrained lots, with little landscape disruption. The technology will lead to increased adoption of energy-efficient heating/ventilation/air conditioning (HVAC) technology, increasing the “electrification” of the energy economy and reducing air polluting emissions. These GSHP systems will impact the national market of heating and cooling systems, with potential annual energy savings of over 6.4 quadrillion BTUs, end-user savings of $77. B in annual energy costs, and reduced peak electricity demand by 144 GW.This SBIR Phase I project proposes to further develop a technology addressing the applicability, desirability and cost-competitiveness of GSHP systems. The chief technical objective of the project is to optimize system components and architectures by increasing fundamental understanding of in-ground heat exchanger performance and installation methods through digital and physical prototyping across a range of real-world conditions. A second technical objective is to improve fundamental understanding of the energy storage capability of the technology and how it can be leveraged through operational cycling to further increase the performance-cost ratio. Studies of physical prototyping, installation and thermal properties will be conducted, in addition to computational fluid dynamic (CFD) simulations. The primary goals are to demonstrate significant benefits in installed performance-to-cost and an installation time of under 8 hours for a typical residential 3-ton system, compared to the current state-of-the-art of 16 hours.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.

小型企业创新研究(SBIR)项目更广泛的影响/商业潜力是，它将显著降低住宅和商业地源热泵系统的初始成本，同时通过扩大地源热泵的适用性来扩大现有市场。该项目将展示一种新型地埋式热交换器的可行性和在真实世界条件下的性能，这种热交换器既便宜又易于安装，即使在空间有限的地块上也是如此，几乎不会对景观造成破坏。该技术将导致更多地采用节能供暖/通风/空调(HVAC)技术，增加能源经济的电气化，并减少空气污染排放。这些地源热泵系统将影响全国供暖和制冷系统市场，每年可能节省超过6.4万亿BTU的能源，最终用户节省77美元。该SBIR第一阶段项目建议进一步开发一种技术，解决地源热泵系统的适用性、可取性和成本竞争力问题。该项目的主要技术目标是通过在一系列真实世界条件下进行数字和物理原型制作，增加对地埋式热交换器性能和安装方法的基本了解，从而优化系统组件和架构。第二个技术目标是提高对该技术的储能能力的基本了解，以及如何通过操作循环来利用该技术，以进一步提高性价比。除了计算流体力学(CFD)模拟外，还将进行物理原型、安装和热性能研究。主要目标是展示在安装性价比方面的显著优势，以及典型住宅3吨系统的安装时间不到8小时，而目前最先进的安装时间为16小时。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
