Abstract

This paper presents an experimental and theoretical study of using the ground and water geothermal affects to the cool the buildings. This done by helical heat exchanger submerged under the well water. Where the tests were conducted in the city of Tikrit / Iraq in hot and dry climate for the period from May to June. The results showed that the use of the water heat exchanger reduces the temperature of the air inside the test room 10 - 15 oC less than the ambient temperature. In addition, the results showed an improvement in relative humidity of 15-20% and a decrease in cooling loads by 50%. The temperature of the well water has great effects on the temperature of the supply air from the heat exchanger. Also, the temperature at the depth of 3 m under the ground will be constant and reached to 21 - 22 oC. The solar radiation has more effect on the ground's temperature at depth 0.25 m. Results showed a significant agreement between theoretical and experimental results.
