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 |
20080308088 | Low Profile Exhaust Hood - A low profile exhaust hood has a high inlet and a high aspect ratio of horizontal to vertical. A sloping wall of the recess guides hot plumes upwardly to the inlet. The inlet is sized to provide an exhaust face velocity that is at least as high as a highest possible plume velocity for a 400 F oven. The inlet is located high and forwardly to cause a suction zone to be generated near the forward edge of the hood to aid in capturing plumes tending to escape which are remote from the sloping wall. | 12-18-2008 |
20090264060 | RECIRCULATING EXHAUST SYSTEM - Systems, devices and methods provide energy recover, modular systems to build and revise commercial kitchen services, closed circuit exhaust, and high efficiency capture and containment of fumes from cooking processes. | 10-22-2009 |
20110143648 | AUTOMATIC DISPLACEMENT VENTILATION SYSTEM WITH HEATING MODE - 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. | 06-16-2011 |
20110250099 | FUME TREATMENT METHOD AND APPARATUS USING ULTRAVIOLET LIGHT TO DEGRADE CONTAMINANTS - 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. | 10-13-2011 |
20120295532 | CHILLED BEAM DEVICES, SYSTEMS, AND METHODS - A chilled beam system may incorporate a terminal unit to provide additional heating and cooling capacity including latent cooling. In a system, terminal units may be distributed and connected to cooperate with a primary air stream from a central air handling unit. The chilled beam and/or terminal units may employ features for enhancing heating mode operation. Control embodiments take advantage of the additional capabilities described. | 11-22-2012 |
20130037017 | LOW PROFILE EXHAUST HOOD - A low profile exhaust hood has a high inlet and a high aspect ratio of horizontal to vertical. A sloping wall of the recess guides hot plumes upwardly to the inlet. The inlet is sized to provide an exhaust face velocity that is at least as high as a highest possible plume velocity for a 400 F oven. The inlet is located high and forwardly to cause a suction zone to be generated near the forward edge of the hood to aid in capturing plumes tending to escape which are remote from the sloping wall. | 02-14-2013 |
20130149947 | OVEN EXHAUST HOOD METHODS, DEVICES, AND SYSTEMS - An exhaust device for convection or combi ovens captures exhaust from opening side-opening oven doors with minimal energy waste. | 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 |
20130291735 | AIR PURIFICATION DEVICES METHODS AND SYSTEMS - A device and method for air purification used in cooling, heating and air ventilation systems. The device has at least one UV light source positioned on an inside portion of a movable access panel so that it moves with the access panel from a first position where the UV source directs UV light towards the inside of the system to purify the air stream inside and to remove contaminants from the surfaces inside the system, to a second position where the UV source directs UV light towards the space surrounding the system so that it purifies the air in the room where the system is mounted. | 11-07-2013 |
20140238380 | OVEN EXHAUST HOOD METHODS, DEVICES, AND SYSTEMS - An exhaust device for convection or combi ovens captures exhaust from opening side-opening oven doors with minimal energy waste. | 08-28-2014 |
20140318733 | CHILLED BEAM DEVICES, SYSTEMS, AND METHODS - A chilled beam system may incorporate a terminal unit to provide additional heating and cooling capacity including latent cooling. In a system, terminal units may be distributed and connected to cooperate with a primary air stream from a central air handling unit. The chilled beam and/or terminal units may employ features for enhancing heating mode operation. Control embodiments take advantage of the additional capabilities described. | 10-30-2014 |
