Patent application number | Description | Published |
20080207109 | Ventilation Register and Ventilation Systems - 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. | 08-28-2008 |
20090032011 | CONTROL OF EXHAUST SYSTEMS - Exhaust capture and containment are enhanced by means of automatic or manual side skirts, a sensitive breach detector based on interference effects, a combination of vertical and horizontal edge jets, and/or corner jets that are directed to the center diagonally from corners. Associated control functions are described. | 02-05-2009 |
20090199844 | EXHAUST HOOD WITH AIR CURTAIN - An exhaust hood captures and contains a thermal plume with a minimum of exhaust air by defining a short-throw planar jet around a protected perimeter. Corner interference is mitigated by various mechanisms including having at least one of adjacent planar jets run only partly along a respective edge such that said first and second curtain jets do not meet at said corner; having a direction of the planar jets proximate corners where they meet being intermediate between respective directions of the jets along respective main portions of the perimeter; or having a direction of the jets of one of the adjacent edges be horizontal while the other is vertical. | 08-13-2009 |
20100005765 | HIGH EFFICIENCY GREASE FILTER CARTRIDGE - 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. The frame permits the flow to exit to a side opposite the face even when the frame is surrounded, edgewise, by a solid structure of the hood opening | 01-14-2010 |
20100294259 | CONTROL OF EXHAUST SYSTEMS - Exhaust capture and containment are enhanced by means of automatic or manual side skirts, a sensitive breach detector based on interference effects, a combination of vertical and horizontal edge jets, and/or corner jets that are directed to the center diagonally from corners. Associated control functions are described. | 11-25-2010 |
20110005507 | REAL-TIME CONTROL OF EXHAUST FLOW - An interferometric detector detects fluctuations in fluid properties in the vicinity of an exhaust hood to control protective skirts that reduce the exhaust air requirement. | 01-13-2011 |
20110021128 | CONTROL OF EXHAUST SYSTEMS - Exhaust capture and containment are enhanced by means of automatic or manual side skirts, a sensitive breach detector based on interference effects, a combination of vertical and horizontal edge jets, and/or corner jets that are directed to the center diagonally from corners. Associated control functions are described. | 01-27-2011 |
20110174384 | REAL-TIME CONTROL OF EXHAUST FLOW - 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. | 07-21-2011 |
20130149949 | CONTROL OF EXHAUST SYSTEMS - Exhaust capture and containment are enhanced by means of automatic or manual side skirts, a sensitive breach detector based on interference effects, a combination of vertical and horizontal edge jets, and/or corner jets that are directed to the center diagonally from corners. Associated control functions are described. | 06-13-2013 |
20130213483 | REAL-TIME CONTROL OF EXHAUST FLOW - 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. | 08-22-2013 |
