Continuous Process for Automotive Cabin Air Dehumidification

In this paper, we demonstrate the feasibility of a novel continuous regeneration process for cabin air humidity control. The technique does not require the use of moving wheels or beds, and may be powered using waste heat. The operation is based on the use of trilobal (wicking) fiber technology. The trilobal fibers are arranged in a continuous parallel array, which is formed into a flat panel water transfer element. The fibers are impregnated with desiccant salt solutions (calcium chloride, lithium chloride, etc.) which are capable of reversible capture of gas phase water molecules. Steady state water transfer was achieved using a number of dessicant salt solutions. The effects of critical variables such as residence time and the quantity of fiber on the level of water transfer were also determined.
