Measurement of internal and effective borehole resistances during thermal response tests
(International Ground Source Heat Pump Association, 2017)
In a conventional thermal response test (TRT), the main parameter evaluated is the bulk subsurface thermal conductivity surrounding the borehole. It is also possible to evaluate the borehole thermal resistance. Several ...
Second-order multipole formulas for thermal resistance of single U-tube borehole heat exchangers
(International Ground Source Heat Pump Association, 2017)
The borehole thermal resistance is both an important design parameter and a key performance characteristic of a borehole heat exchanger. Another quantity that is particularly important for deep borehole heat exchangers is ...
