Patent ID: 10907847

Abstract:
Disclosed is an intelligent heating, ventilation, and air conditioning (“HVAC”) system. Located within an architectural structure, the HVAC system incorporates an airborne contaminant-flow calculator. When sensors (or a human operator) detect an “incident” (e.g., a contaminant is detected or an unexpected breach occurs in the structure that may be associated with the introduction of a contaminant), the HVAC system recalculates airflows for the structure. If the newly recalculated airflow so warrants, the HVAC system protects the structure's occupants from the airborne contaminant by changing the airflow through the structure (e.g., the HVAC system closes a shutter in the air ducts, turns up a fan, or redirects airflow to a standby filtration system). The HVAC system's calculator uses a closed-form solution for calculating the airflow in order to present its results in a timely fashion.
