Abstract

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.

Claims6

Dependent claims

A method for controlling contaminants in air in an environment, comprising:

creating a reference database of the contaminants in the air;
calculating a contaminant concentration of a contaminant in the sample database;
calculating a predicted sensory detection threshold of the contaminant;
wherein the predicted sensory detection threshold is based on a plurality of contaminant sample population percentiles;
comparing the predicted sensory detection threshold to one of a contaminant concentration and contaminant mass in the air;
adjusting the air based on the comparison.
