摘要

In the present work the ground temperature has been validated for climatic condition of Sriperumbudur nearChennai, India to evaluate thermal conductivity and diffusivity of the soil. For the evaluated thermal conductivity of thesoil, an EAHE has been designed for a given dimension of room with optimized values of number of air changes, lengthof pipe, radius of pipe and depth at which heat exchanger to be installed below the surface of the earth. It has beenobserved that there is a decrease of 5 – 6 °C in the outlet air temperature in summer for a number of 5 air changes with0.10 m and 21 m optimized diameter and length of pipe respectively.
