Enhancing thermal comfort in buildings innovations in sustainable cooling and heating systems utilizing geothermal energy

This research paper explores the potential of passive heating and cooling strategies in buildings utilizing geothermal resources. The focus is on renewable energy solutions, including geothermal energy, solar systems, and Earth-to-air heat exchangers, with the aim of reducing energy consumption for cooling and heating loads. The investigation primarily centers on the performance and optimization of the Trombe wall system, a well-known passive solar system. Numerical studies are conducted to analyze the thermal and fluid-dynamical behavior of the Trombe wall system. The findings provide valuable insights into its operational characteristics and efficiency, aiding in the refinement of design approaches and optimization of system performance. The analysis of temperature distributions within the building and underlying soil reveals the stability of soil temperatures throughout the day, indicating its potential as a reliable heat sink and source for heating and cooling. The dynamic variations in room temperatures, influenced by solar flux fluctuations, convection processes, and the functioning of the air-to-earth heat exchanger, highlight the importance of effective system design and control for achieving optimal thermal performance.
