Glass fiber evaporative cooler media, method of forming same, use thereof in an evaporative cooling method, and an evaporative cooler apparatus utilizing glass fiber cooling media

摘要

Hydrophilic glass fibers are formed by coating glass fibers with a blend of an amine-aldehyde with an acrylic. Evaporative cooler pads are produced by coating glass fibers with a blend of an acrylic and an amine-aldehyde during hot melt spinning of the glass fibers into a web, followed by drawing the web to expand the web or mat into a porous pad, and curing the pad to produce a dimensionally stable, hydrophilic, porous, glass fiber pad. Preferably, the glass fibers are coated with a binding/hydrophilic coating formed of a blend of a urea-formaldehyde with an acrylic. A method for cooling air using the hydrophilic, porous, glass fiber pads, and an improved evaporative cooler utilizing hydrophilic, porous, glass fiber pads is disclosed.
