摘要： A method of responding to a condition in an exhaust ventilation system that has an exhaust hood includes receiving, at a control module, an exhaust air temperature signal representing a temperature of the exhaust air in a vicinity of the exhaust hood, the exhaust air temperature signal being generated by a temperature sensor. The method also includes receiving a radiant temperature signal representing a temperature of a surface of a cooking appliance that generates the exhaust air, the radiant temperature signal being generated by a radiant temperature sensor. Further, the method includes receiving a pressure signal representing the pressure in the hood and determining a state of the cooking appliance based on the received exhaust air temperature signal, the received radiant temperature signal, and the received pressure signal. Finally, the method responds to the determined appliance state by outputting a control signal from the control module.

摘要： An exhaust hood may have an exhaust inlet; a shroud having a lower edge and being movable, the shroud being configured to define an enclosed space over and adjacent a cooking surface, the enclosed space being in communication with the exhaust inlet. The shroud is movable to a first position providing clearance between the cooking surface and the shroud lower edge and a second position providing substantially less than the clearance provided by the first position. A vertical jet at the lower edge is aimed upwardly and along an inside of the shroud when the shroud is in the second position and the vertical jet is in the enclosed space. A horizontal jet is provided at a top of the shroud and aimed along an inside of the shroud when the shroud is in the second position and the vertical jet being in the enclosed space.

摘要： A cooking fume mitigation system may have an exhaust hood configured to capture fumes from a cooking appliance, the exhaust hood conveying fumes to a particulate removal stage which conveys fumes to an odor removal stage. The system may also have an inlet volatile organic compound (VOC) sensor upstream of the odor removal stage and an outlet VOC sensor downstream of the odor removal stage. The odor removal stage may include a carbon filter or an ultraviolet light source. The particulate removal stage may include a pocket filter or an electrostatic precipitator filter. The system may also have a controller that receives signals from the inlet and outlet VOC sensors and uses the signals to generate data indicative of a remaining life of the carbon filter.

摘要： A fire safety system particularly adapted for commercial kitchen applications provides control of exhaust levels for energy efficiency and intelligently responds to fires or fire risks. In embodiments, systems may provide early warning of fire hazards or impending fires. Embodiments employ probabilistic estimates with alarms that can be canceled. Embodiments employ classifiers that can make use of alarm cancellations as a mechanism for supervised learning.

摘要： An exhaust apparatus for a conveyor oven includes a first hood linked to a duct at a first end of the duct and connected to a frame configured for mounting on the conveyor oven such that the first hood is positioned directly over a conveyor tray of the conveyor oven. The first hood has at least one grease filter and a recess defined at least in part by an interior wall, the hood interior wall having a first side, a second side opposite to the first side, a bottom edge, a top edge, and opposing side edges. The hood interior wall bottom edge is aligned with a top of the conveyor oven and is aligned directly over an access located in the bounding external surface of the conveyor oven when the first hood is mounted on the conveyor oven.

摘要： Automatic devices that determine when pollutant deposits have accumulated in ductwork may be employed to notify maintenance personnel or automated cleaning equipment of the need for ducts to cleaned or replaced. Various detection devices may be employed to detect a property of accumulated grease and generate an indication of an accumulation. The detection device may present a surface to the fume stream inside a duct. The surface may be cooled to a temperature that represents a worst case temperature so that the accumulation due to condensation on the detector surface is at least as high as the coolest surface in the ductwork which is being monitored. Alternatively, the detection device may be located external to the duct. The detection device may interrogate the surface of the duct through contact or noncontact measurements to determine the thickness of an accumulated grease layer on the interior of the duct.
