Enhanced lithium bromide absorption cycle water vapor recompression absorber

摘要

A Vapor Recompression Absorber (VRA) for reprocessing a concentrated solution of water refrigerant and Lithium-Bromide salt from at least one solution concentrator in a closed chiller system, the VRA being comprised of an upper heat-in absorption chamber and a lower heat- out evaporation chamber and sump separated by a thin polymer heat transfer wall, strong solution from the system applied as a falling film to the heat-in side is recirculated, while strong solution applied as a falling film to the heat- out side and evaporation therefrom transported by a vapor compressor to the absorption chamber and condensed for recirculation, the sump solution being being strengthened and delivered to and evaporated in the absorber of the chiller system for maximized chilling of a water distribution system.
