Schematic Of A Direct Evaporative Cooling System 8 Download A typical direct evaporative cooler is shown in fig. 2 where a fan is used to draw in outside air through a pad wetting media and circulates the cool air through the building [8]. the energy. Direct evaporative cooling systems. in a direct evaporative cooling system outside air is pulled through a water saturated medium (typical cellulose) or air is sprayed with water and cooled by evaporation. the cooled air is circulated by a blower. moisture can be added to the air stream until saturation. dry bulb temperature is reduced.
Schematic Of A Direct Evaporative Cooling System 8 Across the cooling media is 27ºf (as in the above example), the cooling efficiency is 90%. (27 30 = .90). 4) evaporative cooling performance factors: the evaporative cooler performance is directly related to its ability to evaporate water (cool) at a given relative humidity. the dryer the air, the greater shall be the performance. O 1 minute on the sump pump(s).12. verify the low water level float switch located in sump is working p. ope. y and will turn the pump(s) on.13. start up the. fan per manufacturer's instructions. after both the fan and sump are running and operating properly, check that water is not being carried over into the a. Fig. 2.1 working principle of direct evaporative cooling: a schematic diagram; b psychrometric chart. black “dot dash lines” represent constant relative humidity (rh) lines and red “dash lines” represent isenthalpic lines. fig. 2.2 direct evaporative cooler: a cooling pads; b typical cooler unit. For evaporative cooling, this heat is taken from the air, cooling it as it evaporates. this simple, yet most efficient, law of nature has been used by humans for comfort cooling systems sincethe daysof ancientegypt and the persianem pire.

Direct evaporative cooling is the process of evaporating liquid water to the surrounding air and causing its temperature to decease. a typical direct evaporative cooler, as shown in fig. 1, uses a. The results showed that the output temperature of the air varies between 24.9°c and 26.7°c, while the cooling capacity is between 1.06 kw and 2.08 kw and saturation efficiency between 67.23% to 77.27% is achievable. the results showed that evaporative cooling is achievable with feasibility index 11.86 ≤ f*≤ 17.84.
