This project encompasses the fabrication and Computational Fluid Dynamics (CFD) analysis of an Earth Tube Heat Exchanger (ETHE) designed to enhance energy efficiency in HVAC systems for sustainable buildings. The ETHE system leverages the stable underground temperature to precondition incoming air, thereby reducing the load on conventional heating, ventilation, and air conditioning (HVAC) systems. The fabrication process involves constructing a prototype ETHE system using environmentally friendly materials such as high-density polyethylene (HDPE) tubing and a heat exchanger core. This project contributes to the knowledge base on sustainable HVAC technologies, specifically focusing on Earth Tube Heat Exchangers. The combination of fabrication and CFD analysis offers a comprehensive understanding of the system's thermal performance, presenting a promising solution for reducing energy consumption in buildings while ensuring occupant comfort and indoor air quality. The study sets the stage for integrating Earth Tube Heat Exchangers into mainstream HVAC systems, promoting sustainable and energy-efficient building designs.
