Abstract
The effective borehole thermal resistance of a vertical, single U-tube ground heat exchanger is numerically studied. The nonuniform temperature distributions along the perimeter of both borehole and outside diameter of two pipes are taken into account to evaluate effective borehole thermal resistance. A best-fit correlation for effective borehole thermal resistance is proposed, and the dimensionless borehole thermal resistances are compared between the present correlation and other available equations in the literature. It is found that the present correlation of effective borehole thermal resistance is more accurate than those of available formulas.
