Abstract: In order to increase the air humidity in a cabin region of an aircraft equipped with a plurality of seats, a device includes a plurality of humidifying units each arranged in spatial association with a partial number of the seats and a plurality of outlet openings. The humidifying units are each designed to enrich a supplied air stream with gaseous water. The outlet openings are designed to emit the air streams enriched by the humidifying units into the cabin region, such that a partial number of the outlet openings each receive one of the enriched air streams. The air temperature of the enriched air streams is controlled so that the local temperature in a target region served by the humidifying unit does not fall below a dew point.

Abstract: In order to increase the air humidity in a cabin region (10) of an aircraft equipped with a plurality of seats (16; 28), a device (12; 14) is provided, comprising a plurality of humidifying units (26) arranged in each case in spatial association with in each case a partial number of the seats (16; 28) and a plurality of outlet openings (120). The humidifying units (26) are in each case designed to enrich a supplied air stream with gaseous water. The outlet openings (120) are designed to emit the air streams enriched by the humidifying units (26) into the cabin region (10), in each case a partial number of the outlet openings (120) each receiving one of the enriched air streams.

Abstract: The invention relates to a method for separating out substances dissolved and/or undissolved in fluid media. The method is characterized by it being a suitable combination of a membrane filtration technique and an adsorption technique. This enhances the flow and purification capacity by a multiple factor in making a compact, lightweight system possible.
