Abstract

Objectives: To predict the performance and experimental investigations of the Earth Air Heat Exchanger (EAHE) in hot-dry climate. Methods/Statistical Analysis: In this study the advantage of geothermal energy of soil is used to cool the room effectively. This technique used for transferring the cool air to the room by moderating the temperature of the air. The concrete pipes almost first time employed for the current study instead of using PVC and Mild steel pipes. The temperature difference between the inlet and outlet can be calculated from Resistance temperature detectors. Findings: The adequate cooling of the buildings in summer season as well as heating in winter is two basic demands of human bodies in the present society. Both two societal needs fulfil with the help of an Earth air heat exchanger technique. The existing reports for the study makes the use of PVC pipes and some reports use of GI and Mild steel pipes. The more valid results obtained from the current study by use of concrete pipes for investigations of the performance of this system. The temperature drop from inlet to outlet in concrete pipes more at same length of pipes. These pipes are helpful in more cooling in summer seasons. The savage of electricity is increases with the use of concrete pipes and it becomes popular in rural and urban areas day by day. Application/Improvements: In current study the old Earth Air Heat Exchanger system is improved with use of concrete pipes and efficiency of the is system improved by making system free from dust and other contaminated particles. It can be effectively used in rural and urban areas to cool the houses in summer seasons.
