Single and double U-tube ground heat exchangers in multiple-layer substrates

Florides, Georgios A.; Christodoulides, Paul; … - In: Applied Energy 102 (2013) C, pp. 364-373

The efficiency of ground-source heat pumps depends on the correct sizing of the associated ground heat exchangers (GHEs). Multiple ground layers with regard to GHE and the presence of more than one loops in each borehole (multiple U-tubes) are sparsely raised in the literature. Therefore the...
