Abstract
An Environmental Control Systems (ECS) for an aerospace vehicle comprises an air supply airflow path inputting, monitoring, and conditioning air from external to the vehicle, and a recirculation airflow path inputting, monitoring, filtering, and moving air from one portion of the interior of the vehicle to another portion. The air supply airflow can include a dynamically controlled VOC/ozone converter, which can be operated when the aerospace vehicle is on the ground. The recirculation airflow path can include a dynamically controlled regenerative gas contaminant filter and/or VOC/CO2 removal device. The filter/adsorption media of the controlled regenerative gas contaminant filter and/or VOC/CO2 removal device can be regenerated by suppling hot air or a vacuum, and gaseous contaminants can be broken down for removal from the regenerative gas contaminant filter by controlling UV irradiation. The controller can alert a flight crew if air quality falls outside predetermined or programmable parameters.
