An apparatus for humidifying air in an air duct

The invention relates to an apparatus for humidifying air in an air duct (1), comprising a feeding device for a liquid mist (10) and an air conducting device located upstream of the feeding device in the direction of flow (2). In order to provide advantageous humidifying conditions it is proposed that the air conducting device comprises at least one wing (7) which extends transversely to the direction of flow (2) and has an airfoil profile which is pitched against the direction of flow (2).

A humidifier that suppresses formation of a slime, a scale, and a dew bridge in a lower portion of a humidifying member thereby preventing degradation in humidifying performance. The humidifier includes one or more porous metal bodies serving as the humidifying member and including therein a plurality of voids, a fan that blows air to the porous metal body, a water-supplying device (a supply pipe, a reservoir, and a nozzle) that supplies water to the porous metal body, and the porous metal body includes a tip portion formed in a lower end portion, in a protruding shape or a pointed shape.

A call for humidity signal may activate a water valve of a humidifier to cause water to flow onto a humidifier pad within the humidifier. In some examples, a controller may activate the water valve in a pattern such that most of the water evaporates, rather than flowing to a drain system, yet still provides the requested humidity level. In some examples, the controller is configured to cause the water valve to deliver water to the humidifier pad in a water delivery pattern having a controlled period and a controlled duty cycle.
