An HVAC system includes a desiccant wheel, wherein the wheel's
speed varies with airflow, the wheel is energized for at least a
set period at startup, and/or a heat recovery system (e.g., an air-to-air
heat exchanger) upstream of the wheel enhances the system's ability
to dehumidify air.
A desiccant dehumification system uses an air heater incorporating
air feedback from the exhaust and/or the return air fans. The air
and gas are mixed in a single step, two step, or continuous modulation
mixing valve. An outdoor cooking grill style burner allows a small
unit to be made with tight air heating system. One system cools
the return air making it cool and humid. A portion of this air is
then dried by a desiccant dehumidification system which makes hot
and dry output air. The remaining return air is then dried by desiccant
dehumidification system output air to deliver processed air in a
controlled comfort range. A second system mixes return air with
fresh air making mixed return air which is dried in a desiccant
dehumidification system and then cooled to a desired comfort range
without condensation.
A top-emitting OLED device includes a substrate, a first electrode
disposed over the substrate, and an organic EL media disposed over
the first electrode. The device also includes a transparent or semitransparent
second electrode disposed over the organic EL media, and a light
transmissive desiccating film having a host and molecularly dispersed
desiccant material in such host provided on or over the second electrode.
A polymeric substrate for a moisture-sensitive electronic device
includes a polymeric support having a top and bottom surface, and
a desiccant layer disposed over at least a portion of the top or
bottom surface of the polymeric support, or both.
