Abstract
A furnace humidifier uses radial air flow through a spaced stack of annular disks rotated through a water bath to provide humidification with reduced encrustation of the water carrying surfaces from minerals in the evaporating water. The disk array is followed by a damper volume providing more uniform air flow through the disk spaces better utilizing the water on their surfaces.
Claims7
An air humidifier comprising:
- a plurality of annular disks spaced along a substantially horizontal common axis, the disks having radially inner and outer edges, the inner edges defining an inner volume;
- a portion of a lower housing positioned beneath the disks to hold water at a water level;
- a motor assembly connected to the disks to rotate the disks about their common axis so as to change the portion of the disks that is beneath the water level as the disks rotate;
- an air conduit communicating with the inner volume;
- whereby air conducted through the conduit into the inner volume may pass outward between the disks to be humidified;
- further including a tubular chamber having an open end abutting the inner volume and substantially preventing axial air flow from an opening of the inner volume of the disks opposite the air conduit, the tubular chamber further having an opposite closed end removed from the disks, the chamber sized to even the flow of air from the air conduit through the spaces between the disks.
