This paper presents an innovative Borehole Heat Exchanger (BHE) configuration in which the vertical probes are immersed in an artificial fluid, contained in a case separated from the ground by the usual filling material. This system leads to an increased heat transfer within the borehole due to the onset of induced natural convection in the annulus between the protection system and the vertical probes. The related TRCM schemes are presented for grouting filled conditions.

Abstract

This paper presents an innovative Borehole Heat Exchanger (BHE) configuration in which the vertical probes are immersed in an artificial fluid, contained in a case separated from the ground by the usual filling material. This system leads to an increased heat transfer within the borehole due to the onset of induced natural convection in the annulus between the protection system and the vertical probes. The related TRCM schemes are presented for grouting filled conditions.
