Description

<p>A desiccant rotor divided into four sectors realizes a double-stage dehumidification or regeneration in one adsorbent rotor. In this study, the amount of dehumidification and efficiency of two typical configurations of the four-divided silica gel rotor, one is called “adjacent type” whose adsorption or regeneration zones are adjacent to each other and the other is called “diagonal type” in which adsorption or regeneration zones located diagonally opposite to each other, were experimentally investigated and compared with a conventional configuration. It was found that the dehumidifying performance of the “adjacent type” was the highest among these three configurations and the inlet air temperature of 2nd regeneration zone significantly influenced on the amount of dehumidification. Also, measurement of air temperature profiles along with the rotating and axial directions of the rotor helps to understand a simultaneous heat and water vapor transfer occurred in the four-divided silica gel rotor.</p>
