A heat exchange system includes a core of cross flow passages having a reheater, and a condenser that is downstream of and directly interfaces the reheater. A first water extractor is downstream of the condenser, wherein the first water extractor turns a first fluid from the first pass of the condenser back towards the condenser and produces a second fluid that flows into the second pass of the condenser. A second water extractor is downstream the condenser, wherein the second water extractor turns a third fluid from the second pass of the condenser towards the reheater; and produces a fourth fluid that flows into the reheater.

Water extractor device using scuppers

A rigid or semi-rigid demister pad is positioned between an air turbine and an inertial water removal device such as extractor in an air conditioning system for an aircraft. The demister pad comprises packed fibers or strands whose diameter typically ranges from approximately 10 or fewer microns to approximately 280 microns. The demister is capable of catching very small droplets discharged from the air turbine that coalesce into larger droplets that exit the demister pad and enter an adjacent water removal device downstream from the pad to separate the larger water droplets from the stream of air. This avoids using a water separator containing a coalescer bag that requires frequent maintenance and is sensitive to dirt and freezing. The demister can operate at freezing temperature, is not dirt-sensitive and requires no maintenance.

Water removal downstream of a turbine

A recirculating water extractor includes a swirl vane, a converging nozzle, and two sumps. The recirculating water extractor may be designed to reintroduce uncollected water droplets back into the air stream upstream of both sumps, which may provide additional opportunities for separation. The Coanda effect may be exploited to increase the discharge of water along a surface. Utilizing a converging nozzle may intensify the centrifugal force applied to the air stream rich with entrained water and may move more of entrained water into contact with the wall of the nozzle, which, in turn, may enhance the liquid/vapor separation compared to prior art water extractors. The recirculating water extractor utilizing the Coanda effect and the method for removing entrained water from an air stream may be suitable for, but not limited to, applications in the aircraft and aerospace industries, for example, by being included in environmental control systems of aircraft.

Recirculating Coanda water extractor

An environmental control system (ECS) for an aircraft may be employed to regulate temperature of air entering a cabin of the aircraft. During conditioning of the air, condensate may form in the air. A multiple-stage condensate extraction unit may be incorporated into the ECS to remove the condensate. The extraction unit may be provided with two fluid collection stages built into a cylindrical duct. The duct may have a bend therein. One of the collection stages may be positioned on an upstream side of the bend while the second one of the stages may be positioned on a downstream side thereof. The combination of the two stages and their positioning on either side of the bend may provide a particularly compact and efficient condensate extraction unit.

Apparatus and method for extracting condensate

A liquid extractor may comprise a slot in a duct wall and one or more ridges positioned on the interior duct wall surface. A bend in the duct, a swirl device and/or gravity may throw the liquid portion of the flow onto the wall surface. The slot may be oriented longitudinally along the duct. The ridge(s) may intersect the duct and be positioned to direct the liquid on the wall surface to the slot where the water is extracted. An enclosing sump may be positioned on the outside of the duct and over the slot.

Duct wall water extractor

A method and apparatus for extracting water droplets from a water-laden airstream includes introducing the airstream into an extractor duct, imparting a swirling motion to the airstream at a first axial location in the duct, removing water droplets from the airstream that have been thrown to the inner surface of the duct at a second axial location downstream of the first location, and at a third axial location downstream of the second location removing water droplets not removed at the second location. The water removal mechanism at the second location includes a first collection chamber and a first array of apertures circumferentially positioned about the duct and communicating the interior of the duct with the first collection chamber. The water removal mechanism at the third location includes a second collection chamber and an upstream-facing annular ring of smaller diameter than the diameter of the duct for capturing water droplets that have not been collected by the water removal mechanism at the second location.
