Abstract
The purpose of this study is to examine the dehumidification behavior of a block type desiccant unit of organic sorbent. This unit has simple rectangular parallelepiped shape, and initial cost can be lower than the desiccant rotor. This unit will be used in batch system that one unit is used for sorption and another is used for desorption at the same time. Experimental conditions are as follows, sorption air temperature is 18 °C, sorption air relative humidity is 90%, desorption air temperature is 40°C, and desorption air relative humidity is 36%. It was found that completed time of desorption is earlier than that of sorption. As a result, sorption and desorption characteristics of the block type sorbent unit and their overall-mass-transfer coefficients are clarified.
