Optimal geometric configurations for simulating thermal comfort in enclosed spaces using an air-ground heat exchanger

This study focuses on the cooling and the realization of the thermal comfort of a room by a geothermal technique of an air/ground exchanger specifically in a region characterized by a dry climate. By leveraging the bioclimatic features of such a region, the research aims to identify the most suitable configuration for the cavity to achieve optimal thermal comfort. This investigation was carried out using numerical simulations in mixed convection, with a focus on determining how certain parameters affect the thermal comfort. The findings reveal that setting the inlet height (Hinlet) to 0, the outlet height (Houtlet) to 0.45, the depth of the room to 0.6 and Reynold number (Re) to 2000 significantly enhances heat transfer, resulting in improved comfort within the room. The study's conclusions are supported by a series of numerical simulations that confirm the effectiveness and reliability of the model in assessing and optimizing thermal comfort in various enclosed spaces.
