The Effect of Cooling Water Temperature on Cooling Rate and Study of Increasing the Efficiency of Water Coolers in Poultry Housing

Evaporative cooling has been known for centuries, from which various types of cooling devices have been made. But during hot summer days, when the temperature rises above some average value, the designed system may not work properly and users may seek for methods to increase its performance. In this paper the effect of cooling water temperature, entering into the pads, on the evaporative cooling is investigated. Also, the cooler efficiency is calculated and its water consumption per hour is determined. It is shown that decreasing the cooling temperature does not affect the cooling rate significantly, but using compound systems may reduce the water consumption considerably.
