Abstract
Borehole heat exchangers utilize the relatively high temperature of the soil as a heat source for a heat pump systems. By harnessing shallow geothermal energy, they contribute to the reduction of greenhouse gas emissions and the advancement of sustainable, environmentally friendly energy solutions. In this study, a pipe-in-pipe borehole heat exchanger was analyzed using computational fluid dynamics. The investigation focuses on the thermal and hydraulic performance of the heat exchanger, with particular attention given to the impact of non-concentric pipe configurations on essential thermal parameters such as effective thermal conductivity and borehole thermal resistance. A thermal response test was simulated to assess performance characteristic. The developed model replicates different practical scenarios that can occur in real applications and allows for the assessment of the impact of configuration variation on the system’s efficiency over time. The analysis considered both the influence of test duration and the temperature-dependent variation of the fluid’s thermophysical properties over time. The results indicate that concentric configurations have higher thermal efficiency, especially during initial operation, whereas non- concentric configurations exhibit increased thermal resistance and reduced performance. However, these differences diminish over time, showing that moderate eccentricity can be tolerated in long-term operation without significant efficiency loss.
