Evaporative air conditioner

Abstract

Abstract An evaporative air conditioner is provided with a continuously extending water-absorbent air filter pad which is enclosed within a housing so that air entering through openings in the housing will surround the filter pad and flow through the pad substantially uniformly throughout the entire area of the pad. A baffle plate is mounted between the openings in the housing and the pad for deflecting air flowing through the openings into the space between the pad and the housing. A water distribution channel is positioned above the pad for supplying water to the pad, the channel having openings above the pad spaced along the length of the pad. The water distribution channel is supplied with water by a plurality of supply channels which communicate with the distribution channel at spaced locations along the length of the channel so that the pressure of the water is substantially uniform throughout the distribution channel. The filter pad is supported by the top wall of an enclosed water tank, and openings are provided through the top wall of the tank below the filter pad to permit excess water to drain into the tank. An air exhaust tube extends between the top and bottom walls of the tank, and an exhaust grille having an upwardly extending plenum tube which is adapted to extend upwardly through the ceiling of the room to be cooled is telescopingly received in the exhaust tube. A fan may be adjustably mounted in the exhaust tube for drawing air through the filter pad and forcing it into the room.
