Patent number: 11951514Abstract: The present disclosure relates generally to fume hoods, and more particularly to systems and methods for controlling a fume hood airflow using an image (e.g., an optical image, an acoustic image, etc.) of a fume hood opening. A system for controlling a fume hood may include an image capture sensor, a configurator and a controller. The image capture sensor may be positioned to have a field of view that includes at least a portion of a fume hood opening, and may be configured to capture an image that includes at least part of the fume hood opening and/or a person working at the hood. The controller may then provide a control signal to a ventilation device for providing a desired airflow in the fume hood. The control signal may depending on the current size of the fume hood opening as captured by the image capture sensor.Type: GrantFiled: April 8, 2020Date of Patent: April 9, 2024Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Richard E.

Patent number: 11686496Abstract: An HVAC system and method for characterizing a chosen VAV valve involves measuring the valve's volumetric flow rate versus valve position at just one or at some other limited number of data points and comparing that to the average characteristics a rather large group of similar valves. A custom characterization of airflow versus valve position for the chosen VAV valve is then created based on a difference between the characteristics of the chosen valve and that of the group of valves. In some examples, the VAV valve is of a venturi style such that a generic characterization of the group of valves is substantially linear when their flow rates are expressed logarithmically.Type: GrantFiled: March 31, 2020Date of Patent: June 27, 2023Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Wei Hua, Lloyd Nghi Trong Le, David Boisvert
