Development of a Full-Scale Soil-Borehole Thermal Heat Exchanger System
Publication: Geo-Congress 2024
ABSTRACT
Ground source heat pump (GSHP) system has been introduced as an alternative to conventional snow/ice removal systems. The system exchanges heat with the ground through soil-borehole or energy pile heat exchangers with vertical U-tubes. The performance of the heat exchangers depends on the thermal properties of the ground formation and borehole arrays. This study evaluates the design and construction process of a soil-borehole thermal heat exchanger system (SBTHES) installed in a clayey deposit at Arlington, Texas. Parameters, such as total demand heat flux, soil thermal conductivity, and borehole arrays, are involved in the design of SBTHES. In addition, a thermal response test is performed to determine the in situ thermal conductivity of the ground formation in the vicinity of a borehole heat exchanger, as well as the thermal resistance.
