Abstract
This work is oriented to fulfil the cooling or heating demand of building space using ground renewable energy to get the independency on conventional energy. In this paper, EATHE (Earth Air Tunnel Heat Exchanger) simulated model has been developed using ANSYS Fluent. The grid independency study has been done for CFD model at different mash size has and model has been validated by experimental data. Further analysis has been done for EATHE model consists of 50 m length of helical PVC pipe. The diameter of pipe, thickness are 0.15 m and 0.002 m respectively. Velocity of air through the channel is set to 7 m/s. The EATHE is used to cool a building room having cooling load of 0.8 TR and floor area of 156 square feet situated in the dry climate of Bikaner city in Rajasthan, India.
