Patent ID: 8066263

Claim:
A rotary disk humidifier that optimizes the wetted area of the disks to improve humidification of the air by selecting a range of disk average outer radius R o to disk wetted inner radius R i ratios, namely R i /R o comprising: a humidifier housing having a reservoir for holding liquid, said housing having an air inlet and an air outlet, a plurality of generally parallel disks mounted for rotation in the housing adapted to be partly submerged in the liquid in order to provide a wetted radius , said disks having a center of rotation providing an inner and an outer radius R i and R o , the ratio of an inner wetted radius of the disks R i to the outer wetted radius of the disks R o being in the range of 0.06 to 0.54 in order to provide humidification within 10% of an optimum point on a normalized area vs. normalized radius performance curve as generally depicted in FIG. 6 of the present drawings.
