Summary:This paper highlights the findings of a case study of one of the American Recovery and Reinvestment Act (ARRA) ground source heat pump (GSHP) demonstration projects, which is a typical distributed GSHP system installed in a high school at Cedarville, AR. Since the distributed GSHP system provides simultaneous heating and cooling to individual zones in a building, the performance of each individual GSHP unit needs to be monitored and analyzed in order to determine the total heating and cooling outputs of the distributed GSHP system. Challenges and suggested solutions for collecting data and analyzing individual heat pump performance are addressed in this paper. In addition to analysis of utility bills, computer simulations of typical baseline HVAC systems were also performed to determine the energy savings achieved by the GSHP system. The computer model used in the simulations was calibrated with the measured data. Further analysis of the measured data also identified some issues in the design and operation/control of the GSHP system.
