Patent number: 10845130Abstract: A heat exchange system for commercial kitchen installations, having a dedicated plenum to receive combustion emissions separate from cooking emissions, where the plenum has a heat exchange structure that efficiently and directly draws heat from the combustion emissions. The plenum heat exchange structure reduces the air volume that a ventilation hood covering the kitchen appliances needs to process and filter, while concurrently obtaining heat from combustion emissions without interference from cooking emission effluents such as grease, smoke, or particulate matter. Heat drawn out of the combustion emissions can be stored in a thermal reservoir for powering other parts of the commercial kitchen or other uses. The diverted airstream from combustion emissions, once passed through the heat exchange structure, can further ventilate through an additional heat exchanger, to provide tempered air to an interior location, such as the commercial kitchen via an air supply duct in the cooking emission ventilation hood.Type: GrantFiled: January 8, 2018Date of Patent: November 24, 2020Assignee: STREIVOR, INC.Inventor: Jeffrey S.

Publication number: 20200047102Abstract: A filtration system for a ventilation hood includes a first filter and a second filter, operatively disposed in series. The first filter is configured to be mounted within the ventilation hood, and has an air inlet, an air outlet, and a grease outlet. The second filter includes a filter material with an upstream surface and a downstream surface, an upstream housing element abutting the upstream surface of the filter material, and a downstream housing element abutting the downstream surface of the filter material. The housing elements include openings, and hold the filter material in compression.Type: ApplicationFiled: October 18, 2019Publication date: February 13, 2020Applicant: STREIVOR, INC.Inventor: Jeffrey S. Lambertson

Publication number: 20190390859Abstract: An exhaust hood cleaning system for commercial kitchen installations, having a wash control cabinet connected to one or more exhaust hoods over cooking appliance ranges, where each exhaust hood includes a spraying array subsystem within the exhaust hood and a fogging subsystem within the connected flue for the exhaust hood. The exhaust hood cleaning system is electronically controlled, receiving input instructions from any one or combination of an operator interface, fire suppression systems of the building in which the system is installed, and environmental control systems of the building in which the system is installed.Type: ApplicationFiled: April 19, 2019Publication date: December 26, 2019Applicant: Streivor, Inc.Inventor: Jeffrey S.

Patent number: 8857424Abstract: An exhaust hood and related methods for exhausting fumes are disclosed. The exhaust hood comprises a housing forming a collection region having an entry portion and an upper portion disposed above the entry portion, an exhaust inlet coupled with the housing and configured to draw air from the entry and upper portions, and a supply assembly coupled with the housing and configured to output a flow of supply air. The supply assembly is configured to direct a first portion of the supply air across the collection region generally towards the exhaust inlet and direct a second portion of the supply air generally downward away from the collection area. The directed first portion of the supply air divides the collection region into the entry and upper portions. The portion of the supply air directed into at least the first portion or the second portion can be adjustable.Type: GrantFiled: October 6, 2009Date of Patent: October 14, 2014Assignee: Streivor, Inc.Inventor: Jeffrey S.
