The broader impact/commercial potential of this Small Business Innovative Research (SBIR) Phase II project focuses on the high costs and greenhouse gas (GHG) emissions associated with conventional heating, ventilation, and cooling (HVAC) methods. HVAC constitutes approximately 48% of building energy consumption representing a significant cost to society. Much of this energy is generated by fossil fuels, resulting in substantial environmental impacts: carbon emissions associated with residential and commercial use are 35.6% of total US emissions. Geothermal or ground source heat pumps (GSHPs) represent the most energy-efficient and environmentally-friendly HVAC solution currently available, however, their high upfront capital costs have significantly slowed their deployment. The innovation in the present project takes a fundamentally different approach to GSHP heat transfer, resulting in reductions of 50% in installation costs and 20% in operating costs compared to conventional GSHP systems, enabling an expansion of the geothermal market. The present project seeks to thoroughly field test and analyze the performance of the GSHP innovation, optimizing the fabrication and installation parameters, and readying it for commercial deployment.This SBIR Phase II project proposes to address the high installation cost and large, disruptive footprint of conventional GSHP systems. The project objective is to demonstrate a compact, cost-effective, easily-deployable, renewable solution for HVAC. The advection-driven GSHP (AGHP) takes advantage of the 4-5 times greater heat capacity of water than rock. Under the present project, AGHP will advance beyond numerical and laboratory analyses to manufacturing and field testing performance under real-world conditions. The research objectives include: 1) finalization of field site, 2) preliminary design and numerical modeling of the AGHP system for a chosen field site; 3) engineering retrofit design; 4) fabrication of the custom designed submersible pump and heat exchanger; 5) installation and testing of the AGHP system; 6) operation, monitoring, and analysis of the performance of AGHP system, including the development of a comprehensive cost, energy use, and emissions model for the AGHP system; and 7) use of the compiled data to estimate the potential for the economic viability of AGHP in various regions of the United States. The anticipated result of this project is a commercially-ready GSHP product with design and installation guidelines for determining the potential for deploying the innovative AGHP system at any given location.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）II期项目的更广泛的影响/商业潜力集中于与常规供暖，通风和冷却（HVAC）方法相关的高成本和温室气体（GHG）排放。 HVAC约占建筑能源消耗的48％，代表了社会的巨大成本。这种能量的大部分是由化石燃料产生的，从而产生了重大的环境影响：与住宅和商业用途相关的碳排放量占美国总排放量的35.6％。 地热或地面源热泵（GSHP）代表了目前可用的最节能和环保的HVAC解决方案，但是，它们的高前期资本成本大大减慢了部署的速度。与传统的GSHP系统相比，本项目的创新对GSHP传热采取了根本不同的方法，从而降低了50％的安装成本和20％的运营成本，从而降低了地热市场。本项目旨在彻底进行现场测试和分析GSHP创新的性能，优化制造和安装参数，并为商业部署做好准备。该SBIR II阶段项目建议解决常规GSHP系统的高安装成本和大型颠覆性的足迹。该项目的目标是证明HVAC的紧凑，具有成本效益，易于使用的可再生解决方案。对流驱动的GSHP（AGHP）利用了水的4-5倍，比岩石高4-5倍。在本项目下，AGHP将超越数值和实验室分析，以在实际条件下进行制造和现场测试性能。研究目标包括：1）最终确定现场站点，2）所选场地的AGHP系统的初步设计和数值建模； 3）工程改造设计； 4）制造定制的潜水泵和热交换器； 5）AGHP系统的安装和测试； 6）对AGHP系统性能的操作，监视和分析，包括开发AGHP系统的全面成本，能源使用和排放模型； 7）使用编译数据来估计美国各个地区AGHP经济可行性的潜力。该项目的预期结果是一款具有设计和安装指南的商业准备GSHP产品，可确定在任何给定位置部署创新的AGHP系统的潜力。该奖项反映了NSF的法定任务，并被认为值得通过基金会的知识分子和更广泛的影响来通过评估来获得支持。
