  • Real-time control of exhaust flow
    Patent number: 9909766
    Abstract: A flow control system for controlling exhaust flow can measure effluent escaping from the exhaust hood at a given flow rate. An interferometric detector can measure fluctuations in fluid properties external to and/or in the vicinity of the exhaust hood. The flow control system may vary a flow rate of the exhaust hood and/or control exhaust hood structures responsive to the measurements to contain the effluent while minimizing the exhaust of air from the occupied space.

  • Automatic displacement ventilation system with heating mode
    Patent number: 9644851
    Abstract: Displacement ventilation systems are generally poor performers when it comes to heating. The instant patent application discusses devices and systems for improving heating performance while retaining the benefits of displacement ventilation without wholesale co-location of independent space conditioning systems.

  • Fume treatment method and apparatus using ultraviolet light to degrade contaminants
    Patent number: 8002881
    Abstract: An ultraviolet treatment chamber for treating exhaust streams, particularly those containing organic particulates, utilizes ultraviolet light energy very efficiently. This is done by setting up a circulating flow in a treatment plenum so that all of the effluent experiences a substantially uniform residence time without the need for baffles or other flow controllers that would block the ultraviolet light.

  • HIGH EFFICIENCY GREASE FILTER CARTRIDGE
    Publication number: 20100005765
    Abstract: A grease filter has a filtering portion configured such that fumes enter a major face thereof and flow through a grease extraction filter therewithin in a direction parallel to the major face. A frame that fits into an opening of a hood defines a box structure that is configured to allow flow from the end (or ends) of the filtering portion where flow exits.
