Air humidifying method and device for aircraft cabins

摘要

The air humidifier draws air from the cabin (4) and after processing returns it to the cabin. A secondary hot air flow is derived from a hot air stream from the aircraft engine, and this secondary hot air stream is introduced into a boiler (6) enclosing an air-water heat exchanger (17). The boiler is partly filled with water, and generates water vapour in proportion to the flow of hot air. This vapour is mixed at the at the boiler outlet with the hot air stream, and the hot air and vapour mix is injected into the air conditioning circuits of the aircraft.
