Abstract: Khartoum State facing the problem of low productivity of milk cows for milking and due to the high temperatures inside the barns where milk imported from abroad Sudan $ 250 million annually. Was proposed solution to the problem warm environment cools the barns through evaporative cooling was the heat and humidity maximum temperature is calculated after cooling and humidity ratio associated with it and found that it ranged between 14-20 and is suitable for milk cows high productivity and minimum temperature after cooling and relative humidity accompanying ranged between 14-26 can ignore this period because they get in a few days a year. In this project has been tunneling barn design specimen refrigerated dairy cows using evaporative cooling system that contains an automatic gain control to keep the heat index and optimum moisture under the climatic conditions of the mandate of the Khartoum regime and that of need and consumption of milk
