System for targeted local air humidification

摘要

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.

1. A device for increasing the air humidity in a cabin region of an aircraft equipped with a plurality of seats, comprising:
a plurality of humidifying units, each of which is arranged in spatial association with a partial number of the plurality of seats defining corresponding target regions for local air humidification in the cabin region and each of which selectively enriches a supplied air steam with gaseous water, a plurality of outlet openings which are designed to emit the air streams enriched with gaseous water by the humidifying units into the corresponding target regions of the cabin region, wherein a partial number of the outlet openings each receives one of the enriched air streams such that each of the plurality of humidifying units is associated with a partial number of the outlet openings, a plurality of temperature sensors, each of which is arranged in associated ones of the target regions and each of which detects a local temperature in the associated target region, and a plurality of first control units, each of which is electrically connected to one of the plurality of temperature sensors and each of which controls an air temperature of the enriched air stream so that the detected local temperature in the target region does not fall below a dew point in the target region.
