jsc2023e010169 (1/30/2023) --- CapiSorb Visible System flight unit capillary condensing heat exchanger (CCHX) in N240 room 133B. The CapiSorb Visible System will be launched on SpaceX CRS-27 in March 2023 to the International Space Station to demonstrate a liquid sorbent-based system that leverages the advantages of liquid control through capillary action to remove carbon dioxide from crewed atmospheres...The CapiSorb Visible System Capillary Condensing Heat Exchanger, shown here pre-flight, uses capillary surfaces and active cooling to condense water vapor from heated, humid air during microgravity experimentation. The capillary surfaces enable control and passive transport of fluids. The CapiSorb Visible System investigation demonstrates a liquid control using capillary forces, over a range of liquid properties that are characteristic of liquid carbon dioxide sorbents.
