Sistema de climatização com energia geotérmica: estudo teórico de sistema de resfriamento e aquecimento

Abstract

This study presents a comprehensive methodology for designing geothermal systems based on the Canadian well, focusing on Brazilian climatic and geological conditions. The theoretical framework integrates earth-air heat transfer concepts and thermodynamic parameters, establishing relationships between soil thermal conductivity, system geometry, and energy efficiency. The proposed method includes thermal load calculation according to ASHRA,2015 models, careful selection of piping materials, determination of optimal air velocity, and experimental validation through temperature, humidity, and static pressure measurements. The results demonstrate the system’s technical and economic feasibility, particularly when combined with photovoltaic solar energy, potentially reducing the investment payback period to 4-6 years in the national context. Beyond energy benefits, the study highlights CO2 emission reductions and potential integration with other renewable sources. As future perspectives, further experimental studies in different climatic regions of the country and the development of specific technical standards are recommended to expand the adoption of this sustainable technology.
