Abstract:
This paper describes testing of four-bed molecular sieve (4BMS) development hardware in support of future operations of the International Space Station (ISS) Carbon Dioxide Removal Assembly (CDRA). During 1998, testing of a MSFC 4BMS included operations with the 4BMS inlet air drawn directly from the cabin atmosphere instead of the baseline air source downstream of a Condensing Heat Exchanger (CHX), operating with high carbon dioxide (CO2) loading, and long duration operation in a power save mode. Additionally, testing with increased coolant water temperature was performed to determine effects on the systems CO2 removal performance.
