Abstract

Experimental investigations for sorption and desorption behaviors in a circular-tube fluidized bed were carried out using organic sorbent particles for the development of a desiccant air conditioning system. Mixing of the fluidized bed intensified with increasing velocity of the air flow passing through sorbent particles. The effective mass transfer coefficient increased with increasing air flow velocity. Additionally, a dehumidifying system of circulating fluidized beds with sorbent particles circulated by air flow was created to perform continuous dehumidification. Experiments were conducted to grasp the continuous dehumidification characteristics of the sorbent particles, and the dehumidification behavior was evaluated according to the sorption and desorption amount.
