Experimental performance of a direct evaporative cooler operating during summer in a Brazilian city

Review on Evaporative Cooling Systems

“…The latent heat follows the water vapour and diffuses into the air. The minimum temperature that can be obtained is the wet bulb temperature of the entering air (Camargo et al, 2005;Heidarinejad and Bozorgmehr, 2008;Abbouda and Almuhanna, 2012).…”

“…In direct evaporative cooling, Heidarinejad and Bozorgmehr (2008) cited lots of works on modelling of direct evaporative cooling, which includes Camargo et al (2005) presentations on the principles of operation for the direct evaporative cooling system for human thermal comfort, and the mathematical development of the equations of thermal exchanges, allowing the determination of the effectiveness of saturation; Dai and Sumathy (2002) investigated a cross-flow direct evaporative cooler, in which the wet honeycomb paper constitutes the packing material and the results indicated that there exists an optimum length of the air channel and the performance can be improved by optimizing some operation parameters. Liao and Chiu (2 0 0 2 ) developed a compact wind tunnel to www.gjournals.org 14 simulate evaporative cooling pad-fan systems and tested two alternative materials.…”

Experimental study of air evaporative cooling process using microporous membranes

“…Numerous studies analyzed the possibilities of using the evaporative cooling in various options, to maintain comfort conditions in living quarters and to lower air temperature in industrial facilities [1]. This type of air cooling can be characterized by less energy consumption compared to conventional solutions used in air conditioning [2][3][4][5][6][7][8][9][10]. The disadvantages of evaporative cooling include dependence on the outside air parameters and the lack of possibility of air drying.…”
