abstract

This work presents a virtual coaxial Borehole Heat Exchanger (BHE) energy balance simulation in Chachimbiro, Ecuador. The purpose of this study was to estimate the power generation and optimize the engineering parameters from a virtual coaxial BHE of 1500 meters depth on the mentioned site. The methodology used was the modeling simulation based on mass and energy balance through AMEsim software, and the parameters employed in the model considered the previous location surveys besides a sensitivity analysis of geometry, pipe materials, and BHE insulation depth. The results showed that a single coaxial BHE on Chachimbiro would have a thermal power potential between 3–4 MW, and its efficiency would mainly depend on the thermal conductivity of the pipes plus the insulation casing depth.
