Abstract :
Based on the principle of superposition, the Infinite - length Linear Heat-source Model is applied to the analysis of the long-term performance of Ground Heat Exchanger for Ground Source Heat Pump. It is shown that the inlet and outlet temperatures of the Ground Heat Exchanger vary with the start time of the operation even if under the same annual dynamic load. The result suggests that the load distribution affects the performance of GSHP even if just the time sequences varying. Therefore the start time of the operation must be considered in the feasibility analysis of a GSHP system.
