Publication number: 20180363923Abstract: A system and method for controlling the exhaust flow rate in an exhaust ventilation system including an exhaust hood positioned above a cooking appliance. The method can include measuring a temperature of the exhaust air in the vicinity of the cooking appliance, and measuring a radiant temperature of a surface of the cooking appliance, and determining an appliance status based on the measured exhaust air temperature and radiant temperature, and controlling the exhaust flow rate in response to the determined appliance status.Type: ApplicationFiled: August 28, 2018Publication date: December 20, 2018Inventors: Andrey V. LIVCHAK, Chester RACZEWSKI, Derek W. SCHROCK

Patent number: 9645009Abstract: In embodiments, a control system for a UV air treatment system, especially one used for cleaning a fume stream such as in a kitchen exhaust system, detects a need for cleaning maintenance on the UV light source based on changes in light intensity. The system further detects the light intensity each time the UV light source is cleaned to determine if the drop in intensity after cleaning indicates that the UV light source should be replaced. The cleaning and replacement requirements are indicated automatically by a user interface.Type: GrantFiled: July 9, 2015Date of Patent: May 9, 2017Assignee: OY HALTON GROUP LTD.Inventors: Andrey V. Livchak, Chester Raczewski

Publication number: 20110120314Abstract: An air ventilation system, comprising an air inlet for admitting contaminated air into the ventilation system, an air outlet for discharging decontaminated air from the ventilation, and an ultra-violet light source disposed therebetween. The ventilation system has a filter disposed upstream of the ultra-violet light source. The filter has a grease particle separator with at least two layers of expanded metal associated therewith. Each has a predetermined number of apertures forming a reticulum. A cartridge filter may be provided for each grease particle separator and disposed upstream thereof. Each cartridge filter and associated grease particle separator preferably forms an integral filtering unit and may be placed at any location of the system.Type: ApplicationFiled: February 3, 2011Publication date: May 26, 2011Inventors: Erik MAGNER, Chester Raczewski, Joe Profenna
