In the evolving landscape of sustainable energy solutions, Earth-Air Heat Exchangers (EAHEs) have emerged as vital contributors. This study focuses on the performance and design of EAHEs, using soil samples from Wardha district, Maharashtra, India, analyzed through Computational Fluid Dynamics (CFD). The results reveal exciting insights, particularly regarding material-specific performance. Copper demonstrates an impressive 24 °C temperature drop in just 5 minutes at velocities of 3.5 and 5 m/s, while High-Density Polyethylene (HDPE) performs well with a 22 °C drop in 10 m for smaller diameter pipe. These findings emphasize the potential of EAHEs for rapid and efficient heating and cooling applications. Beyond traditional HVAC practices, this research contributes to optimized configurations and enhanced thermal performance, making EAHEs integral in sustainable technology for various applications, from buildings to agriculture. This study provides valuable insights for advanced design strategies and operational guidelines, positioning EAHEs as pioneers in sustainable HVAC technology and paving the way for a more environmentally conscious future.

摘要

In the evolving landscape of sustainable energy solutions, Earth-Air Heat Exchangers (EAHEs) have emerged as vital contributors. This study focuses on the performance and design of EAHEs, using soil samples from Wardha district, Maharashtra, India, analyzed through Computational Fluid Dynamics (CFD). The results reveal exciting insights, particularly regarding material-specific performance. Copper demonstrates an impressive 24 °C temperature drop in just 5 minutes at velocities of 3.5 and 5 m/s, while High-Density Polyethylene (HDPE) performs well with a 22 °C drop in 10 m for smaller diameter pipe. These findings emphasize the potential of EAHEs for rapid and efficient heating and cooling applications. Beyond traditional HVAC practices, this research contributes to optimized configurations and enhanced thermal performance, making EAHEs integral in sustainable technology for various applications, from buildings to agriculture. This study provides valuable insights for advanced design strategies and operational guidelines, positioning EAHEs as pioneers in sustainable HVAC technology and paving the way for a more environmentally conscious future.
