A silica-base monolithic adsorbent was prepared by sol-gel synthesis with a corrugated ceramic fiber sheet as a matrix and assembled in an adsorptive dehumidifier of rotary type, which operates with a thermal regeneration cycle. High efficiency of dehumidification was confirmed at a regeneration temperature as low as 80°C when the rotation speed or cycle time was adjusted to the optimal value. A prototype air conditioning unit equipped with the balanced flow dehumidifier was examined in a direct pass ventilation mode. A satisfactory decrease in enthalpy of product air relative to room air was observed. Changes in the state of air during processing are discussed rather rigorously in terms of a humidity chart.
