Abstract
Evaporative cooling systems is widely used in poultry barn . In this experiment the cellulose evaporative cooling pads with 10 cm thickness is most commonly used in Iraq were tested in the workshop of the College of Agriculture during summer / 2011 .Using a new methodology in a wind tunnel to determine the water flow on the pad and air flow through it, as well as the water consumption and saturation efficiency of the pad three water disturbed represent main plot 6,8 and 10 l/min and subplot the air speed 1.4,1.6,1.8 and 2 m/s .The result showed that when water flow increased from 6 to 8 to 10 l/min the temperature among the pads was increased too . When the air speed increased from 1.4, 1.6, 1.8 and 2 m/s, the temperature among the pads was decreased. The result showed when water flow increased from 6 to 8 to 10 l/min, the saturation efficiency increased too. When the air speed increased from 1.4, 1.6, 1.8 and 2 m/sec, saturation efficiency decreased. When water flow increased from 6 to 8 to 10 l/min the water consumption increased too. When the air speed increased from 1.4,1.6,1.8 and 2 m/sec evaporative water increased from 19.0 , 22.6, 24.1 and 24.9 l/h too .We concluded that the best speed gives the best indicators of air through the pad was 1.4 m / s and the best discharge of 10 l/min which gave the highest cooling efficiency and the highest reduction in temperature in front of cushions and less amount of water steamed.
