Rotary disk humidifier

A rotary disk humidifier assembly comprising:

• a housing;
• a plurality of generally parallel disks rotatably mounted in the housing, each disk having an outer diameter edge Ro and an inner diameter edge Ri;
• a reservoir of liquid in the housing;
• an air inlet formed in the housing to provide for airflow within the housing;
• and
• a control for maintaining a liquid level to optimize the humidification function of the assembly by maintaining the liquid level in the housing to provide an optimum wetted disk area above the liquid level and exposed to the airflow, the control being positioned on the housing according to an optimization formula for calculating an optimal Ri/Ro ratio.

A rotary disk humidifier assembly comprising:

• a housing;
• a plurality of generally parallel disks rotatably mounted in the housing, each disk having an outer diameter edge and an inner diameter edge;
• a reservoir of liquid in the housing;
• an air inlet formed in the housing to provide for airflow within the housing, the disks oriented within the housing adjacent the air inlet so that the airflow is directed diametrically across the outer diameter edge Ro toward the inner diameter edge Ri of the disks, wherein the inner diameter edge is adjacent a center point of the disk;
• and
• a sensor unit for optimizing the humidification function of the assembly by maintaining a liquid level in the housing to provide an optimum wetted disk area above the liquid level and exposed to the airflow said sensor for raising liquid level from the outer diameter of the disks toward the center of the disks so the distance from the center to the liquid level is about 25% to 35% of the distance from the center of the disks to the average outer diameter of the disks.
