Hybrid Heat Pump

Project Purpose: This project monitored a ground source heat pump with solar recharge.
Project Abstract: Weller Elementary School in Fairbanks, Alaska has a novel hybrid ground source heat pump (GSHP) that uses a solar collector array with an in-ground loop system to seasonally charge the ground with heat. Thermal energy stored in the ground is extracted over the winter to supplement the school’s heating. The hybrid system was installed as a proof-of-concept experiment for potential hybrid systems in Interior Alaska. Solar recharge is effective at raising the ground temperature and thus improves the performance of the heat pump. The heat pump had an average COP of 3.73 during its first year of operation; however, a longer study would provide a better understanding of the extent of solar recharge that is required to maintain the heat pump COP. Further analysis of the costs of the heat pump system as part of the overall assessment of school energy costs is also recommended.
