• Abstract:

  This paper presents a numerical study based on Computational Fluid Dynamics (CFD) to
  evaluate the thermal potential of a Ground-Air Heat Exchanger (GAHE) as a sustainable
  ecotechnology, to contribute to the thermal comfort of buildings. The numerical modeling was
  carried out considering two geographical locations in Mexico, the rural community "Jicarero"
  in Jojutla Morelos and "La Rosilla" Durango, for the meteorological conditions corresponding
  to the warmest and coldest day of the year 2020. The results show the potential of the GAHE
  as heating and cooling passive system of buildings, respectively, because for the coldest day
  in "La Rosilla" Durango there was an average temperature increase of 4.76 °C at the GAHE
  outlet and for the warmest day in Jojutla Morelos there was an average temperature decrease
  of 5.83 °C.
