ABSTRACT:
An in-duct humidifier has a permeable rectangular pad to be placed in a heated air stream. Water dripping onto the top of the pad is evaporated by the air stream which is passing through the pad to thereby increase its humidity. The pad is held in a frame and the frame is mounted in the humidifier's housing. The frame holds the pad by an arrangement of sloped surfaces and narrow projections to minimize the area of the frame in direct contact with the pad. By minimizing the contact area between the pad and the frame, the amount of water flowing onto the frame and evaporating from the frame is minimized, thereby reducing the rate and amount of minerals dissolved in the water which are deposited on the frame surfaces.
