Dehumidifiers honeycomb core component of a wheel, wheel carriers and by the special ceramic fiber composites made of silica gel; runner by a special seal on both sides of divided into two areas: dealing with regional and regional regeneration; when needs moist air through the dehumidification wheel handling areas, wet air rotor water vapor is absorbed by the activity of silica gel, dry air handling fans were sent to deal with the space; constant slow rotation of the wheel carrying the trend in saturated water vapor into the regeneration area; regeneration in the region of high temperature air blown into the reverse of adsorption of water makes the runner was desorption was fan exhausted to the outside, so that wheel to restore the moisture absorption capacity and the completion of the regeneration process, continuously rotating wheel, the dehumidification and the regeneration cycle carried out in order to ensure sustained and stable desiccant dehumidifier state.
