According to a ground coupled heat pump (GCHP) system for a commercial building in Jiangyin city, Jiangsu province, a model was built based on TRNSYS software to simulate and analysis its coefficient of performance (COP) under different working conditions. The results showed that the heating season performance factor (HSPF) of heat pump system was 3.31 in summer and the seasonal energy-efficiency ratio (SEER) was 3.37 in winter when the pipe buried depth was 100 meters. Analytic hierarchy process (AHP) was used to evaluation the suitability of GCHP system, and compared with the conventional system in terms of economic and environmental performance. It was found that the operating cost of GCHP system was 75.6% of the conventional system, the primary energy ratio was 13% higher, save coal amount was 1.71 tons, greenhouse gas reductions was 4.47 tons, and the all-yearly energy-efficiency ratio was 2.74. The GCHP system presents high suitability regarding its advantages in energy-saving, economic, and environment protection.
