Abstract
A hollow fiber membrane dehumidification device that possess hollow fiber membranes that cause the compressed air supplied from one end to the interior to flow through and at the same time discharge moisture in the compressed air to the outside, and by so doing exhausts the compressed air to the other end as dehumidified air. There is a reflux route that causes a portion of the dehumidified air exhausted from the hollow fiber membranes to flow back to the outside of the hollow fiber membranes as purged air and a variable restrictor that is provided on the reflux route that increases or decreases the opening-closing volume in accordance with the increase or the decrease of the pressure of the compressed air that flows through the interior of the hollow membranes.
