Abstract
A hollow fiber membrane dehumidification device with a housing chamber open to atmosphere via a through hole. Hollow fiber membranes are disposed in the housing chamber and cause compressed air entering from one end to flow through and be discharged at the other end as dehumidified air by discharging moisture to the outside housing chamber. A reflux route is provided to permit a portion of the dehumidified air to flow back to the housing chamber as purged air. First and second orifices are provided on the reflux route wherein the second orifice has an opening diameter larger than that of the first orifice.
