Abstract
Heat exchange performance of vertical U-tube heat exchanger was studied with two different borehole fill materials and CFD software. Borehole surface temperature and water temperature distribution were simulated on the condition of continuous operation for 8 h in winter with inlet water temperature being 10 °C. The results show that there is no obvious difference on heat exchanger performance between the two different borehole fill materials.
