Vertical ground heat exchanger pressure loss – Experimental comparisons and calculation procedures
Vertical ground heat exchangers (GHEs) used with ground source heat pump systems have been constructed in a variety of configurations including single U-tubes, double U-tubes, quadruple U-tubes, and coaxial-type. Selections of vertical GHE other than single U-tubes are often motivated by a desire to decrease the borehole thermal resistance and therefore reduce the required amount of drilling and/o
