The air humidity is controlled using the
water moistened surface of the bladed
rotor and the water level in the tank. As
the water level rises, the rotor blades
are submerged more deeply into the
water, increasing the surface area of the
blades that becomes wet.
The passing air flow absorbs moisture
from the wet blades, in accordance with
a specific reference value that is set as a
constant. However, as a rule the set rela-
tive humidity is converted to the relevant
absolute humidity at 21 °C (factory
setting) and then controlled.
