A fume hood monitor includes a fume hood monitor controller that is configured to display one or more of the fume hood parameters on a display of the fume hood monitor and to communicate with the mobile device. The mobile device includes a mobile device controller that is configured to pair the mobile device with the fume hood monitor. Once paired, the mobile device controller is configured to receive two or more of the fume hood parameters from the fume hood monitor controller, display two or more of the received fume hood parameters on a display of a user interface of the mobile device, and receive a user interaction via the user input device of the mobile device. The user interaction may allow a user to manipulate information that is displayed on the display of the mobile device regarding the fume hood.

Methods and systems for remotely interacting with a fume hood using a mobile device

A fume hood monitor includes a user interface including a display, a wireless interface and a memory that stores a plurality of fume hood parameters and one or more default display settings. A controller is configured to display one or more of the plurality of fume hood parameters on the display formatted in accordance with the default display settings. The controller is configured to detect a presence of a mobile device, and in response, receive personalized display settings from the mobile device via the wireless interface and to display one or more of the plurality of fume hood parameters on the display formatted in accordance with the personalized display settings. When the mobile device is no longer detected, the controller is configured to display one or more of the plurality of fume hood parameters on the display formatted in accordance with the default display settings.

A building management system (BMS) for a medical facility that includes a plurality of rooms with at least one of the rooms having a plurality of sensors. An elevated infection risk determination system is operatively coupled to the plurality of sensors for determining when an elevated infection risk occurs in one or more of the rooms. The BMS may include a memory for storing one or more programmable infection risk compliance parameters, an input port for receiving an elevated infection risk alert for the particular room in the medical facility, a control port for providing control commands to one or more building components of the building management system, and a controller. The controller may be configured to provide control commands via the control port in response to receiving the elevated infection risk alert for the particular room based at least in part on one or more programmable infection risk compliance parameters to help mitigate the elevated infection risk in the particular room.

A venturi valve having a valve housing that includes a narrowing section extending between a broader upstream end and a narrower valve throat followed by a broadening section downstream of the valve throat, and a valve member configured to be situated in the valve housing and movable along a valve axis in an axial direction of the valve housing. The venturi valve includes a plurality of flow influencing features positioned in a reattachment region of the valve member and/or extending inward from an inner wall of the valve housing. The plurality of flow influencing features are configured to reduce perturbations in an air flow passing through the venturi valve thereby reducing rattle from the venturi valve.

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.

Controlling a fume hood airflow using an image of a fume hood opening

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.

Devices and systems which control the flow of fluid through a conduit are described herein. One flow control device that controls the flow of fluid through a conduit, includes a body having an axis and defining a passage that allows fluid to flow from an upstream position to a downstream position, the valve body having a converging portion in the upstream position with an inner surface that curves gradually inward, but having an annular rim formed by a portion that extends outward from the inward curving shape, and a throat between the converging and diverging portions; and, a flow regulator supported within the body for controlling the flow of fluid through the conduit, the flow regulator having an annular seating surface configured to contact the annular rim of the body.
