Abstract: An aircraft humidification system includes a first duct configured to guide a first air stream, and a second duct configured to guide a second air stream, the second duct including a humidifier for humidifying the air stream in the second duct. The humidification system further includes a first conduit for directing part of the second air stream to the first duct. The first conduit includes a first conduit inlet leading into the first duct and a first conduit outlet extending from the second duct. A second conduit directs part of the first air stream to the second duct, the second conduit including a second conduit inlet leading into the second duct and a second conduit outlet extending from the first duct. The first conduit outlet is arranged downstream of the humidifier, the second conduit inlet is arranged downstream of the first conduit outlet, and the first conduit inlet is arranged downstream of the second conduit outlet.

Abstract: A humidifier, preferably for aircrafts, includes a humidifier device, an outlet fan as well as a heat exchanger and a heat exchanger fan. The humidifier device is provided with an intake for a mixture of non-humidified air and recirculated air as well as an outlet for the air mixture. A recirculation fan is placed in a recirculation loop between the outlet and the intake so that a portion of the air mixture should be recirculated back to the humidifier device. An aircraft can be equipped with such a humidifier and a humidifier method used in an aircraft.

Abstract: A sorption drying system for dehumidification of a moist gas stream, includes a mass of absorbing material, a moist gas stream arranged to flow through at least a part of the absorbent mass, and a heated stream of regeneration gas arranged to flow through at least a part of the absorbent mass. The sorption drying system further includes structure for deflecting a part of the dehumidified gas stream after flowing through the absorbent mass, a cooler for cooling the deflected dehumidified gas stream, and structure for returning the cooled deflected dehumidified gas stream to the moist gas stream at the inlet into the absorbent mass. At least a part of the cooled deflected dehumidified gas stream is arranged to flow through the absorbent mass in a channel separated from the moist gas stream.
