Abstract: Wet-surface heat exchangers are analyzed in order to determine the configuration that optimizes the performance. The objective is to cool a stream of air to a temperature lower than the inlet wet-bulb temperature by the evaporation of water. Three laboratory models and a commercial prototype were analyzed. They are a unidirectional, a counter-flow, a counter-flow closed-loop configuration and a cross-flow closed-loop commercial unit, respectively. It was found that dry-bulb temperatures considerably lower than the inlet wet-bulb temperature can be easily achieved. In fact, the inlet dew-point temperature can be approached with moderate flow rates and simple geometries.
