Patent ID: 7077187

Claim:
A regenerative energy and/or mass exchange assembly, comprising: a) an exchange media; b) a first chamber having a first fluid channel adjacent the exchange media to pass a first fluid stream through the exchange media; c) at least a second chamber having a second fluid channel adjacent the exchange media to pass a second fluid stream through the exchange media, the first and at least second chambers separated by a divider; d) at least one fluid stream diverter adjacent the exchange media, the at least one diverter having an adjustable orientation relative to the chambers and providing separate flow communications to the chambers through the respective fluid channels, the at least one fluid stream diverter having a radial extent that is less than the functional radial extent of the exchange media, this functional radial extent of the exchange media being defined by the fluid conducting area of the exchange media adjacent the fluid channels; and e) at least one housing connected to one end of the exchange media and the fluid channels being provided in the housing, wherein the at least one housing has interior walls defining an inner enclosure and a connection portion and a dispersion portion which are in fluid communication with each other, and the at least one fluid stream diverter is provided in the inner enclosure; and wherein, at any given diverter orientation, the separate flow communications are not in fluid communication with the same chamber; wherein the dispersion portion comprises the first and at least second chambers; wherein the exchange media is housed in a plurality of media cavities that are separated from one another in cross section and extend in parallel along the exchange media, and wherein the plurality of cavities that house the exchange media are disposed within a central housing, the assembly has a first end housing and a second end housing disposed on either end of the exchange media, and a first fluid stream diverter is disposed in the first end housing and a second fluid stream diverter is disposed within the second end housing.
