ABSTRACT:
A membrane humidifying device is disclosed that can operate with normal potable quality water without a demineralizer and which prevents the transport of microbes, particulates, dissolved salts and liquid water to the airstream. It is positioned in the flow path of air to be humidified and comprises at least one membrane cell and a means for introducing water into each cell. The membrane cell is comprised of at least one sheet of a hydrophilic membrane and at least one screen. Ambient or low pressure water is introduced into the membrane cell(s); at least a portion of which contacts or passes through the screen(s); contacts the hydrophilic membrane(s); and is osmotically transported across the membrane(s) where it evaporates into the airstream.
