Experimental Measurement of Effectiveness for desert air cooler and comparing with comfort Condition for people

Abstract

evaporative cooler and then calculate the supply air temperature from the cooler and comparing with comfort condition for space users . The experemental effectivness of desert air cooler is equal to ( 76 % )
This paper is studying variation of temperature for 24 hours from each month in summer season and apply this reading for all month day ( i.e 24 *30*5 =3600 hours) where selecting design day from each month.
The experimental measurement proofed that is less than the comfort condition requirement about ( 38 ) % from summer season which is leading to thinking by a replacement although the cheap and poor of power consumption by the desert air cooler comparing with air conditioner working by refrigeran
