Integrated simulation of buildings and evaporative cooling systems

Characterizing the performance of alternative evaporative cooling pad media in thermal environmental control applications

“…Therefore, the present study aims to assess the techniques feasibility of thermal environmental control systems which could be inexpensive and visually attractive cooling systems. One such solution is a system which includes evaporation of an exposed water film in that water is allowed to fall vertically over the elements such as palm-coir fiber material, nonwoven fabric or other filaments, thus exposing the maximum surface area of the water to the passing airflow with the help of forced or natural ventilation (Giabaklou and Ballinger, 1996;Mathews et al, 1994;Abdalla et al, 1990). The arrangement of the fabric lines such as coir fiber or nonwoven fabric forms easily a water curtain through which the air flows horizontally.…”

Evaluating the potential use of direct evaporative cooling in Australia

“…-A humidity ratio limit of 0.012 kg/kg is assumed, in compliance with the ASHRAE comfort zone [19]. -It is assumed that the evaporative cooler will operate with a conservative effectiveness of 0.85 [15,21].…”

Speculation in the feasibility of evaporative cooling

“…Different configurations of evaporative-cooling systems are briefly surveyed [3,4,12]. The common practice with evaporative systems is to use total outdoor air.…”

“…Due to its simplicity, evaporative cooling of air was the oldest method adopted by man to realize, or improve, human comfort through reducing the temperature [1][2][3]. However, it has been relatively renounced, for a long period since the commercial onset of the air-conditioning trade, in favor of mechanically-refrigerated systems.…”
