Abstract

A dehumidifying apparatus is provided. The dehumidifying apparatus includes a desiccant dehumidifying unit, a recovery channel (20) disposed to pass air through a first section (32) of the desiccant dehumidifying unit, for evaporating and condensing moisture of the desiccant dehumidifying unit. A first inlet channel (8) is disposed to pass through a second section (31) of the desiccant dehumidifying unit, for allowing air to flow therethrough and eliminating moisture from the air. A second inlet channel (9) is disposed to directly introduce external air to pass through a third section (33) of the desiccant dehumidifying unit, for recovering heat of the desiccant dehumidifying unit.
