Humidity Control System with Adsorption Materials

Abstract

The present study introduces a humidity control apparatus which can hygienically and automatically maintain an appropriate humidity level of indoor air without either a water supply or a drainage system. In humidification using this apparatus, the desiccant takes up water vapor from the outdoor air in the adsorption process, and releases it indoors by desorption. Therefore, no water supply is required. An apparatus having no water supply is hygienic, because it does not propagate bacteria and does not scatter the calcium and magnesium salts found in water. In dehumidification using this apparatus, water vapor is removed from the indoor air by the desiccant and is released outdoors by desorption, eliminating the need for a drainage system. The absence of a drainage system also eliminates such problems as water leakage and installation.
