  • Patent number: 10746419
    Abstract: When mineral components such as calcium carbonate and magnesium are contained in humidifying water and a humidification plate has holes and high humidifying efficiency, scales may be locally generated at an end or vicinities of the holes on a windward side. When minute voids in the humidification plate are clogged due to the scales, water absorption capability at a scale generation region is significantly reduced. A problem can arise requiring to replace the humidification plate even when a region other than the end and the vicinities of the holes is satisfactory, whereby replacement cycles are shortened. To address the problem, plural openings in a plate thickness direction are distributed on a flat plate surface of a water absorbing humidifying material. Thus, in an airflow direction of air sent from end sides of the water absorbing humidifying material, opening areas of the plural openings on one end side are increased.
