In this study, a two-vessel circulating-fluidized-bed in which particulate sorbents are circulated by air was created to confirm that moisture could be transferred between two air flows continuously, and to investigate its basic behavior. The amount of humidification and dehumidification, which means the amount of moisture transferred between two air flows, was evaluated when changing the air flow velocity and humidity conditions of the air flow. As a result of the experiments, it was found that the amount of humidification and dehumidification influences by the circulating amount of particulate sorbents, and there is an optimum condition for the circulating amount. As the air flow velocity increases, the moisture transfer amount increases because the amount of circulating sorbents also increases. On the other hand, if the amount of circulation sorbents is too large, the moisture transfer amount decreases. Moreover, even if the air flow humidity is changed, no significant difference is found in the circulation amount, but it was found the amount of humidification and dehumidification increases as the relative humidity difference between the two air flows increases.
