The conventional cooling systems in hot and dry climate regions are insufficient and could not meet the requirements of the summer season severe conditions. The low cooling efficiency of such systems can be promoted by combining the systems with an earth and water heat exchanger systems. The present study aims to achieve a proper environment for cooling the living buildings. This target could be achieved by using a geothermal system. The environment conditions are tested. The tests are applied on carefully, for a single room, which is well-isolated using wood. This room is connected to two pipes, which is pass underground and underwater heat exchanger pipes. Solar intensity, ambient temperature, humidity, and temperatures in underground pipe, underwater pipe and the test chamber, all are recorded. All tests are carried out in April, may, June and July, respectively. The obtained results indicated that the air temperature inside the test room has been decreased by 40% compared with the case of unused of a heat exchanger. A comparison between the theoretical and experimental results is done. In addition, the results showed that the air-cooling temperature in the case of using an underground pipe is less with 3 0C degrees compared with that of the underwater pipe. The reduction in the air-cooling temperature compared with the ambient temperature is (12-18) degrees
