Abstract
A method and system for cooling an internal space are provided. A laminate of a hydrophobic membrane and a hydrophilic membrane includes a superabsorbent polymer disposed on or encompassing the hydrophilic membrane. The superabsorbent polymer increases the wicking capacity of the hydrophilic membrane so that water from a source is distributed more rapidly across the hydrophilic membrane. The distributed water is evaporated from the hydrophilic membrane, causing evaporative cooling of the laminate and surrounding air stream(s). The cooled air stream(s) are used to cool the internal space.
