AIR MIXER WITH WATER SEPARATOR

摘要

An air mixer (10), with a water collector (46), is disclosed for supplying recirculated cabin air in aircraft. In the preferred embodiment: used cabin air flows over pipes of colder fresh air to cool the used air and condense out most of the moisture contained in it; the fresh air and used air are passed over opposite faces of a ring of stator vanes (36), thereby imparting swirls to both types of airstreams; and the streams meet at the trailing tips of the stator vanes, where they corkscrew together to throw remaining coalesced moisture against a collection trough (40), from where it is discharged. The airstreams can now be injected into the cabin without droplets raining down on the passengers, nor ice clogging any pipes for the fresh air, which is typically supplied at below-freezing temperature.
