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: A humidification apparatus which makes possible individual humidification of the air in a cabin of a passenger or cargo aircraft makes available a conditioning fluid to be ejected into the cabin from an outlet nozzle (10). The conditioning fluid contains as a component water which is sprayed at a spraying point in very close spatial association with the outlet nozzle (10). To avoid undesired local cooling of the cabin air caused by vaporization of the sprayed water, the conditioning fluid contains an air flow conducted to the outlet nozzle, into which the water is sprayed. The air flow is supplied to the spraying point at a temperature which is higher by a defined amount than a desired effective temperature of the air flow after emerging from the outlet nozzle. In another embodiment the conditioning fluid contains water as its only component, the water being sprayed at a temperature above the cabin temperature.

Abstract: The present invention relates to an evaporator arrangement for an air conditioning system of an aircraft, wherein a bypass conduit is provided which can be connected such that if required at least part of the airflow bypasses an evaporator. Advantageously this makes it possible in the case of malfunction of the evaporator to maintain the functionality of the air conditioning system.

Abstract: An insulation arrangement includes an insulation packet that is made up of insulation material completely encased by a film, and that is arranged in an interspace between an inner trim component and an outer skin of an aircraft. The insulation packet does not completely fill the interspace, but rather leaves an air space. The film consists of a differentially gas permeable film material that provides a differentiated diffusion resistance with respect to water vapor diffusing therethrough, dependent on the direction of the diffusion through the film. Preferably the resistance to diffusion of water vapor into the insulation packet through the film is higher than the resistance to diffusion of water vapor out of the insulation packet through the film. The accumulation of moisture in the packet is avoided.

Abstract: In a method for the separation of supercritical gas from substances dissolved in the gas with a membrane through which the gas passes while the substances dissolved in the gas is retained, a pore-free membrane of a polymer perfluoro-2,2-diemthyl-1,3-dioxole is used as a membrane in the separation process.
