Abstract    Water cooling by ambient takes place with two mechanisms of heat and mass transfer. Using packings at Wet Cooling Towers has disadvantages such as obstruction, reduction of life expectancy and production of algae and fungi. In Shower Cooling Towers types of towers packings are completely removed and water intake is in direct contact and heat transfer takes place in two ways of latent and sensible. In this article mathematical modeling and simulation towers the ruling is using differential equations. Differential equations derived using the laws of conservation of mass and energy and numerical solution is solved with a computer program and the operation of shower cooling towers in different environmental conditions has been observed. These towers in the area of cold and dry and warm and dry has a high efficiency. In very hot areas by reducing the drops diameter, the tower outlet temperature can be improved.
