Air Revitalization System Integration

This paper will present a status review of Spacecraft Air Revitalization System (ARS) integration using regenerable techniques. The paper will address concepts of integration of individual subsystems into an Air Revitalization System, as well as integration of components within subsystems. An ARS design is presented based on the Electrochemical Depolarized Carbon Dioxide Concentrator Subsystem, the Sabatier Carbon Dioxide Reduction Subsystem, the Static Feed Water Electrolysis Subsystem, a condensing Humidity Control Subsystem, and a Water Handling Subsystem to perform the functions of CO₂ removal, CO₂ reduction, O₂ generation, humidity control and by-product water distribution, respectively. The paper will also highlight the numerous advantages of this integration. Trace contaminant control and the nitrogen supply are not included in the ARS described in this paper.
