Abstract
A rotary disk humidifier of the type that has multiple parallel spaced disks rotatably mounted in a water reservoir in a housing with controls for maintaining the water level in the housing to obtain an optimum wetted disk area above the water level exposed to air flow to achieve optimum humidification. At one theoretical extreme, the water level is at or above the center of rotation of disks decreasing the area of the disks exposed to free air flow through the housing. At the other theoretical extreme with the water level just at or slightly above the outer diameter of the disks, there is a grossly insufficient wetted area of the disk to approach the optimum area. Between those extremes there is a mathematical optimal range of the ratio inner wetted diameter of the disk Ri to the outside wetted diameter of the disk Ro (or the average outer diameter of the disk—the disk may not be circular) of about 0.30.
