Study of thermal performance enhancement in geothermal energy pile
Geothermal energy pile is a proven source of renewable energy for space heating and cooling. It harnesses the constant ground temperature for human comfort due to its thermal inertia.Geothermal energy pile is defined as a dual-purpose structural element and an innovative way of reducing the carbon footprint of any new building constructed on pile foundations.
Geothermal energy piles are a direct adoption of vertical borehole closed loop ground source heat pump (GSHP) technology into pile foundations where closed heat exchanging loops are installed within the pile. Despite many studies in the past on geothermal energy pile, there are still unanswered questions regarding how to increase its thermal performance.
To increase the thermal performance of geothermal energy pile, there is a need to improve its thermal energy storage capacity. In this study, different types of heat exchanger piles will be designed with the aim of investigating their thermal performance, and thermo-mechanical behaviour under heating-cooling cycles.
