| Abstract: | Base on several common U-tube heat transfer models of ground source heat pump,this paper proposes a transient heat transfer model for single U-tube vertical heat exchanger.Simulates the winter operation condition by adopting explicit finite difference method.The change rules of the exit water temperature of the U-tube and the distribution of ground temperature are obtained. |
