Earth-to-air heat exchangers (EAHE) can reduce the energy consumption required for heating and cooling of buildings. The composition thermal characteristics soil influence exchange capacity, moisture furthermore affect performance EAHE. aim this study was to compare EAHE in dry artificially wetted soil. Tests were carried out Basra Province (Iraq), a semi-desert area. Two experimental built poultry barn tested from June 2013 September 2013. pipe buried at 2 m deep. One exchanger operated (DE), while other one (WE). In WE system, drip tubing placed 10 cm above air around exchanger. Air temperatures inlet outlet both as well temperature deep continuously monitored. results confirmed that wetting improves general efficiency. coefficient (COP) earth-to-air system evaluated on basis ratio between removed or added input. During day, with an average COP 6.41, cooled more than DE which reported value 5.07. On average, hottest hours 37.35°C it 38.91°C. Moreover, during nighttime, warmed system.
