Type of article: Article


Based on the energy conservation equation for the unsteady state flow, obtains the variation of the fluid temperature in U-tube with the axial direction, and establishes three-dimensional numerical model of coupled heat transfer between U-tube ground heat exchangers and soil. Comparing with the analytic solution and DST model in TRNSYS, the numerical model can improve the accuracy of transient heat transfer simulation. With a constant external load, analyses the relations among the inlet/outlet fluid temperature, the heat transfer capacity and the external load.
