Popis: The implementation of passive technology in buildings for space heating and cooling to reduce the energy consumption is relatively new in Indian climatic conditions. This technology is known as Earth Air Heat Exchanger (EAHE) system. Although, various studies have been conducted in India of EAHE but minimum studies have been conducted considering the cross-sectional geometry of the pipe having different diameter. Studies of the researchers in India were limited to the investigation of the potential and variable affecting the performance of EAHE. This study aims in investigating the appropriate pipe geometry that will anticipate the optimum temperature reduction through Computational Fluid Dynamics (CFD) for achieving thermal comfort. For the investigation of four different pipe geometries, different diameter and arrangement of pipe this paper utilizes Ansys FLUENT v15.0. software. Through thorough investigation of the study it was found that the triangular-corrugated pipe showed best temperature reduction during summers as well as winter season. Further enumeration also results that EAHE system is beneficial to use during both the seasons in Indian climatic conditions.
