A comparison of measured and predicted performance of a ground-source heat pump system in a large building.

Author(s) : CANE R. L. D., CLEMES S. B.

Summary

A building energy analysis model, and a ground heat exchanger model have been used together to simulate the performance of a closed-loop ground-source heat pump system. Predicted electrical energy use and demand and entering water temperatures to the heat pump system are compared to measured data from the same building. Predictions in both areas compare favorably to the measured data. Additional runs were undertaken to assess the sensitivity of the entering water temperature to reductions in installed heat exchanger length from the original design. Under favorable conditions, considerable reductions in the installed heat exchanger length would be possible.
