Abstract

Airborne contaminant detection and localization systems include an HVAC system having a duct, a first vent connected to a first indoor space, and a second vent fluidly connected to a second indoor space, with the second vent being downstream from the first vent in a flow direction along the duct. A monitoring system includes a first and second sensor elements arranged proximate the first and second vents, respectively, the sensor elements configured to detect one or more airborne contaminants. A central unit receives sensor data from the sensor elements. The central unit includes information regarding a location of each of the sensor elements within the duct. The central unit determines the presence and intensity of an airborne contaminant in the duct from the sensor data and establishes a detection zone that includes a portion of the vent having a highest detected intensity of the airborne contaminant.
