Summary

PARALLEL PASSAGE ROTARY WHEEL REGENERATORS WITH SILICA GEL ON THE PASSAGE WALLS ARE USED AS DEHUMIDIFIERS FOR AIR-CONDITIONING APPLICATIONS. THESTUDY PRESENTS AN INVESTIGATION OF TRANSIENT MASS TRANSFER IN A PARALLEL PASSAGE DEHUMIDIFIER WITH A THIN LAYER OF SILICA GEL ON THE PASSAGE WALLS. A TWO-FILM RESISTANCE MODEL WAS USED TO APPROXIMATE THE OVERALL TRANSFER RESISTANCE BETWEEN THE PROCESS AIR AND THE SOLID DESICCANT. ISOTHERMAL TRANSIENT MASS TRANSFER EXPERIMENTS USING PARALLEL PASSAGES WITH SILICA GEL COATED WALLS WERE CONDUCTED AND ANALYZED. THE TWO-FILM MODEL AGREES WITH THE EXPERIMENTAL RESULTS WHICH MAYBE EXTENDED TO OTHER SOLID DESICCANTS.
