HUMAN FACTORS APPROACH TO CONTROL CONTAMINANT CONCENTRATIONS IN AIRCRAFT SUPPLY AIR FROM ENGINE AND APU BLEED AIR AND GROUND AIR SOURCES, AND IN RECIRCULATED AIR BEING DELIVERED TO AIRCRAFT CABINS FOR THE OPTIMIZATION OF USER EXPERIENCE AND ENERGY CONSUMPTION

摘要

An Environmental Control System includes a sensor, an air purification subsystem, and a controller in communication with the sensor and air purification subsystem. The sensor detects a contaminant in the air and generates a contaminant signal. The controller compares the contaminant signal to a predicted sensory response threshold. When the contaminant signal reaches the predicted sensory response threshold, the controller commands the air purification subsystem to alter a condition in the air.
