ABSTRACT:
A spray pad humidifier including a housing having two side wall portions extending perpendicular to each other along one edge, and being interconnected along the opposite edge by an arcuate wall. One of the side wall portions is provided with an opening communicating with the return cool air plenum of a furnace, and the other side wall portion is provided with an opening communicating with the hot air supply plenum of the furnace. A one-piece evaporator pad is configured to extend over both openings, and a water spray nozzle is mounted on the housing for spraying water into the housing and onto the portion of the pad extending over one of the openings. Reinforcing ribs are formed on the housing to not only provide channels within the housing for holding the evaporator pad in the operative position, but also to provide troughs for collecting drain water within the housing.
