Alternate approach to the calculation of thermal response factors for vertical borehole ground heat exchanger arrays using an incomplete bessel function
(International Ground Source Heat Pump Association, 2017)
This article presents yet another methodology for the calculation of dimensionless thermal response factors for vertical borehole ground heat exchanger (GHX) arrays, which is a concept introduced by Eskilson (1987). The ...
Transient thermal resistance of borehole heat exchangers for hourly simulations of geothermal heat pumps systems
(International Ground Source Heat Pump Association, 2017)
The correct design of borehole fields requires the correct evaluation of the transient ground thermal response in time, but also the accurate estimation of the borehole (BHE) thermal resistance, expecially the grout ...
Investigation on the effects of different time resolutions in the design and simulation of BHE fields
(International Ground Source Heat Pump Association, 2017)
The correct design of a field of Borehole Heat Exch angers (BHE) requires the knowledge of ground thermal properties, heat pump performance and building heating and cooling demand. The sequence o f heat pulses from (to) ...
Numerical simulation of pile geothermal heat exchanger with spiral tube considering its thermo-mechanical behavior
(International Ground Source Heat Pump Association, 2017)
Pile geothermal heat exchanger (PGHE), which utilizes the building foundation piles as part of the geothermal heat exchangers (GHEs) for a ground-coupled heat pump (GCHP) system, has been attracting the interests of ...
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 ...
