International Space Station Carbon Dioxide Removal Assembly (ISS CDRA) Troubleshooting and Evaluation

摘要

An important aspect of air revitalization for life support in spacecraft is the removal of carbon dioxide from cabin air.Several types of carbon dioxide removal systems are in use in spacecraft life support.These systems rely on various removal techniques that employ different architectures and media for scrubbing CO,,,such as permeable membranes,liquid amine,adsorbents,and absorbents.Sorbent systems have been used since the first manned missions.The current state of key technology is the existing International Space Station (ISS) Carbon Dioxide Removal Assembly (CDRA),a system that selectively removes carbon dioxide from the cabin atmosphere.The CDRA system was launched aboard UF-2 in February 2001 and resides in the U.S.Destiny Laboratory module.
