Abstract: A simulation model was built for the thermodynamic system of the ground source heat pump (GSHP) based on the G-function theory of the underground heat exchanger (UGHE), and an analysis method for the long-term operation of the GSHP system was proposed. Taking the severe cold region as example, the system winter heating operation conditions in the last 3 years were studied. The fluid temperature variations at the inlet and the outlet of the UGHE, the coefficient of performance and the energy consumption of the heat pump and the system were analyzed simulationally and the results were compared with the measured data. The results show that the model and method are feasible, providing an effective approach for further forecast and analysis.

Key words: thermal engineering, ground source heat pump (GSHP), underground heat exchanger (UGHE), operation station
