Three different design options for closed-circuit evaporative cooler cores are compared by way of numerical examples obtained with the use of computer programs written for the three cases. It is concluded that bare-tube cooler performance can be considerably enhanced by the judicious use of fill material without resorting to the use of fins to increase the mass transfer area.read more

Experimental Investigation of the Performance of Two-Stage Evaporative Coolers
TL;DR: In this paper, the authors investigated the thermal effectiveness and the air-side pressure drop of single-and two-stage evaporative coolers, and found that the thermal performance of the single-stage, direct-contact evaporative cooler with a cooling tower is higher than that of the system without one.
