The Earth air heat exchanger is a better passive technology to the use of geothermal energy. The findings from the study brings us that technology of varying temperature with the soil temperature found many benefits like energy saving and environment preservation. These benefits may help us lot in future in the field of renewable energy resources which is peak demand of the society. The loss of energy can be minimized with the help such type of systems. In this research paper efforts are made to analyze the accomplishment of a low cost cooling system of outdoor air for hot-dry climate. The effect of velocity, length and drop in temperature of the air is studied at the inlet and outlet of the pipe. The results show that maximum temperature drop available at low velocities because air gets larger time to get heat transfer in the underground pipe in soil and also the greater length of the pipe of earth air heat exchanger has more effect on performance of earth air heat exchanger.
