Abstract
Tests of an integrated 4-Bed Molecular Sieve Carbon Dioxide Removal System (CDRA), a Mechanical Compressor Engineering Development Unit (EDU), and a Sabatier Engineering Development Unit were conducted at NASA Marshall Flight Center in 2005 to evaluate the performance of a closed loop Air Revitalization System (ARS). A previously developed model for the integrated ARS was validated and correlated using the test data. Test data, including profiles of molecular sieve 5A bed pressure, CO2 accumulator pressure, CO2 delivery rate from the compressor, on/off operations of the compressor and relieving operation of the pressure relief valve were analyzed and compared with predictions using the integrated model. Findings from analyzing the test data, such as air leak rate to desorption beds, CO2 co-adsorption on 13X of desiccant beds, improvement in thermal modeling, etc. were reported.
