Fluid-to-ground thermal response factors of single-line bore fields with isothermal fluid: Dataset

This dataset reports very accurate tables of dimensionless fluid-to-ground thermal response factors that yield directly the time evolution of the mean fluid temperature for any single-line bore field with up to four borehole heat exchangers (BHEs) subjected to a time constant heat flux. The working condition considered, namely isothermal fluid, is very similar to the real one, where the BHEs are fed in parallel with the same inlet temperature. The dimensionless-time interval considered ranges from 10^-4 to 10^6. For a ground with thermal diffusivity equal to 7.5 × 10^-7 m2/s and a BHE radius of 7.5 cm, it corresponds to a time interval from 0.75 s to 237.8 years.
