1. An air duct comprising an apparatus for humidifying air in the air duct, the apparatus comprising:
at least one outlet opening or outlet slot in the air duct for generating a liquid mist, and
at least one pair of wings located upstream of the at least one outlet opening or outlet slot in a flow direction of air wherein a flow passage for the air is formed between the two wings forming each pair of wings, with the at least one outlet opening or outlet slot positioned, viewed transversely to the flow direction of air, between the two wings forming each pair of wings, and the two wings of each pair of wings each have a surface that is essentially curved from a front edge of the wing to a rear edge of the wing, creating an airfoil profile which is pitched against the direction of flow of the air and produces an acceleration of a flow velocity of the air flow,
wherein a pitching of the two wings of each pair of wings at a rear edge of the airfoil profile produces air vortexes for gripping liquid mist introduced into the air flow.
