Title: Earth Air Heat Exchangers for Passive Air Conditioning: Case Study Burkina Faso
Author: Traoré E. S.; Coulibaly Y.; Woodson T.
Abstract: An Earth Air Heat Exchanger is a novel way to cool and heat buildings using the ground temperature. Earth Air Heat Exchangers are cheaper and they use less energy than traditional air conditioning. These factors make it a perfect technology to cool houses and buildings in Burkina Faso, a developing country with a major indoor cooling demand. This study shows that in Burkina Faso it is possible to build a simple EAHX to cool down ambient air by 10°C which in turn can cool down a room by 1°C-5°C. The EAHX will be 30 meters long, buried 1.5 meters in the ground and use a ventilator with a flow rate of 90 m3/h. In total the EAHX will cost CFA 300,000 ($US 600).
