Abstract
A five hour regenerate, nonventing Humidity and CO2 Control Subsystem (HCCS) technology demonstration unit is being developed for potential use in an Advanced Extravehicular Mobility Unit (AEMU) for Space Station application. The HCCS incorporates a weak base anion exchange resin packed in a metal foam matrix heat exchanger. This system simultaneously removes CO2 and water vapor with the resulting exothermic heat of reaction rejected to the heat exchanger. The system has no moving parts resulting in a highly reliable, simple configuration. Regeneration may be accomplished via internal heating and vacuum.
