ABSTRACT:
In a method and apparatus for adding controlled quantities of moisture to a body of air, a spray nozzle produces an atomized spray of finely divided water particles and a substantially closed through chamber around the spray nozzle has an air inlet and outlet, a chimney portion extending upwardly from the spray nozzle and a sump portion below the spray nozzle. A pressure is produced at the outlet that is less than at the inlet to produce an updraft through the chimney portion utilizing the updraft in one direction and the forces of gravity in the other for selecting usable water particles in a smaller size range that are capable of being airborne in the updraft and be carried through the outlet and be readily evaporated into a body of air externally of the through chamber and rejecting unusable water particles in larger size ranges incapable of being airborne in the updraft and carried through the outlet by the updraft, the unusable water particles flowing by the forces of gravity countercurrent to the updraft into the sump portion and drain away through a drain hole. The method and apparatus is readily adapted to be used in combination with a forced air furnace and air duct distribution system or as a self contained air humidifying unit not associated with the furnace or its air duct distribution system. For a chimney portion of a given height a variation in the size of the inlet for passing air to the through chamber varies the amount of updraft and thereby the quantity and to a limited extent the size of the water particles passing the outlet for controlling the amount of moisture added to the body of air and balancing the device to the needs of a given installation.
