Earth-air- tunnel heat exchanger (EATHE) systems are inadequate to meet the requirements of thermal comfort in summer and winter in a country like Iraq. The presence inlet air to enter at the top of minaret and different column of air pressure increases the natural air movement in the lining of the minaret built of bricks drill (wet) equipped with water spraying system, and minaret continues within the earth deeply 4m. Air moves to spend pottery pipes that are wetted in view of ground water into the earth. The heat exchangers are air-cooled and moistened and access to the prayer hall through four outlets, the removal of the accumulation of warm air to the outside through the windows at the base of the dome. The heat exchanger model based on the development of computational fluid dynamics (CFD) and validation of the simulation results and experimental data obtained. The results showed that the use of natural ventilation through the minaret can reduce the temperature of the air temperature 19 °C when she was abroad 47.3 °C and improvement in the relative humidity to 22%. Summer high temperature 9 °C when I was abroad 10 °C winters. To increase the air column and section Wind-catcher (minaret) makes the heat exchanger system (MEAHE) a means of self-sustainable cooling to reduce energy consumption.

Keywords: Wind catchers, Heat exchanger, Dome, Minarets, Environmental design, Ventilation, Hot day.
