A goal of the Tribal Colleges and Universities Program (TCUP) is to increase the science, technology, engineering and mathematics (STEM) instructional and research capacities of specific institutions of higher education that serve the Nation's indigenous students. Expanding the STEM curricular offerings at these institutions expands the opportunities of their students to pursue challenging, rewarding careers in STEM fields, provides for research studies in areas that may be culturally significant, and encourages a community and generational appreciation for science and mathematics education. This project aligns directly with that goal, and moreover will increase the data available to industry and the general public on the feasibility of the use of air-source heat pumps (ASHPs) in cold climates.University of Alaska Fairbanks, Bristol Bay Campus will conduct laboratory tests of at least three models of ASHPs to characterize efficiency at different outdoor temperatures and heat loads. The resulting data will be used to create an ASHP performance model that will be used to identify boundary conditions for which savings in fuel are no longer achieved, considering the additional fuel that needs to be burned in a power plant to produce the electricity for the ASHP. A control strategy for turning the ASHP on and off will be created to save fuel. A long-term model will be developed that estimates the annual savings in fuel achieved by using an ASHP as a supplemental heating system controlled with the developed control strategy. The long-term model may be applied to twelve rural Alaska communities to determine the potential benefit in a variety of real-world conditions.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.

部落学院和大学方案的一个目标是提高为全国土著学生服务的特定高等教育机构的科学、技术、工程和数学教学和研究能力。扩大这些机构的STEM课程设置，扩大了学生在STEM领域追求具有挑战性和回报的职业的机会，为可能具有文化意义的领域提供了研究，并鼓励社区和一代人对科学和数学教育的欣赏。该项目直接与这一目标相一致，而且将增加工业和公众在寒冷气候中使用空气源热泵（ASHP）的可行性的数据。阿拉斯加大学费尔班克斯，布里斯托湾校区将进行至少三个模型的ASHP的实验室测试，以表征在不同的室外温度和热负荷下的效率。由此产生的数据将用于创建一个ASHP性能模型，该模型将用于确定不再实现燃料节省的边界条件，同时考虑到需要在发电厂燃烧的额外燃料，以产生用于ASHP的电力。 将创建用于打开和关闭ASHP的控制策略以节省燃料。将开发一个长期模型，估计每年节省的燃料实现使用ASHP作为补充加热系统控制与发达国家的控制策略。该长期模型可应用于阿拉斯加州的12个农村社区，以确定在各种现实条件下的潜在效益。该奖项反映了NSF的法定使命，并已被认为是值得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的支持。
