An analysis of thermal performance of a vertical Borehole Heat Exchanger (BHE) from a close loop Ground Source Heat Pump (GSHP) located in Guayaquil-Ecuador is presented. The project aims to assess the influence of using novels heat transfer fluids such as nanofluids, slurries with microencapsulated phase change materials and a mixture of both. The BHEs sensitive evaluation is performed by a mathematical model in a finite element analysis by using computational tools; where, the piping array is studied in one dimension scenario meanwhile its surroundings grout and ground volumes are presented as a three dimensional scheme. Therefore, an optimized model design can be achieved which would allow to study the feasibility of GSHP in buildings and industries in Guayaquil-Ecuador.

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.
