moreThe earths inside temperature is commonly higher than the outside air temperature in winter and lower in summer so it can makes the use of the earth convenient as warm source or cold sink respectively. Earth air heat exchanger can contributes to reduce in energy consumption. Numbers of research have been carried out on Computational Fluid Dynamics analysis of EATHE systems and still it requires optimum redevelopment. In the present work a 3D CAD model was developed for CFD analysis of earth air tube heat exchanger (EATHE) system. The obtained simulated results were compared with experimental results obtained from experimental setup installed at Bhopal situated in Central India. The temperature of earth at a certain depth about 2 m to 3 m of ground remains nearly constant throughout the year this constant temperature is called the undisturbed temperature of earth. The performance evolution was carried out to check the effect of pipe length, air flow velocity, depth of buried pipe and pipe diameter of EATHE system for summer cooling. The result shows that this system is more convenient only for summer cooling and not suitable for winter heating.
