[TRNSYS-users] TESS library - GHP library - Vertical BHE, U-tube - Fluid-to-ground resistance

[Damien Casetta <damien.casetta@gmail.com>]

Hi,

When using a vertical borehole heat exchanger (with known resistance), how the so-called "fluid-to-ground" resistance is defined? Practically, in the particular case of a U-tube heat exchanger, is it an "effective" thermal resistance (if there was only one tube) or the thermal resistance for a single tube?
One more thing, the unit is not that clear ("any"). Is it [W/(m.K)]?

Thanks in advance, 

Have a nice day, 

Regards,
