AI Technical Summary
Existing aircraft environmental control systems have difficulty effectively removing fog and vapor from cabin air during ground operations, causing free water to wet the adsorption elements, affecting the efficiency of volatile organic compound filters and potentially introducing unpleasant odors or increasing pressure loss.
The system employs a two-stage hollow fiber filter system, consisting of a first-stage and a second-stage hollow fiber filter. Each stage contains activated carbon and hydrophobic pleated hollow porous media. Free water is collected and discharged through the hydrophobic media. Combined with a bypass valve design, the airflow path is controlled to ensure air quality and system efficiency.
It effectively removes mist and vapor, prevents the adsorption element from getting wet, maintains the efficiency of the volatile organic compound filter, reduces pressure loss, and maintains evaporative cooling function by re-evaporating free water, thereby improving cabin air quality and system performance.
