DEHUMIDIFICATION DEVICE AND DEVICE

摘要

A dehumidification and ventilation unit 10 attached to a housing 2 has an electrolytic dehumidification element 30 for decomposing moisture in the internal space S1 of the housing 2, and an air hole 30a for allowing air to pass between the internal space S1 of the housing 2 and the external space S2 of the housing 2. Thus, in a dehumidification device provided with the dehumidification element, problems accompanying pressure changes within the housing are prevented and an efficiency of dehumidification by the dehumidification element is improved over cases where no means for passing air between the inside of the housing and the outside of the housing is provided.
