Patent number: 10744356Abstract: 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.Type: GrantFiled: September 17, 2019Date of Patent: August 18, 2020Assignee: Oy Halton Group Ltd.Inventors: Andrey V.

Patent number: 10634365Abstract: A services supply device for a commercial kitchen includes multiple wall modules that are interconnectable to form a continuous wall. The continuous wall is defined by a pair of common substantially planar surfaces, one at the front side of the wall and one at the back side of the wall, spaced apart by some distance. The interior of the wall between the front and back sides forms a cavity. A portion of the cavity may be configured as an exhaust duct that conveys exhaust fumes away from a cooking appliance serviced by the services supply device, while another portion may be configured as a filter. The exhaust duct may have an inlet positioned on one of the sides of the continuous wall. The individual wall modules may be formed from functional units stacked on top of each other.Type: GrantFiled: December 19, 2014Date of Patent: April 28, 2020Assignee: OY HALTON GROUP LTD.Inventors: Andrey V.

Patent number: 10480797Abstract: A flow control device has a duct section with a plurality of damper blocking elements, each having a major plane. The damper blocking elements are pivotably connected to the duct section and movable in a range that is limited to ensure that, when the duct section is mounted in a preferred orientation, the damper blocking element major planes always form an angle of at least 45 degrees from the horizontal throughout the range. The range is such that the plurality of damper blocking elements can selectively close and open the duct. The blocking elements can completely close the duct, for example, to block natural convection.Type: GrantFiled: July 31, 2017Date of Patent: November 19, 2019Assignee: OY HALTON GROUP LTD.Inventors: Andrey V.

Patent number: 10365003Abstract: A ventilation system includes a supply register with a displacement-type diffuser providing a flow of ventilation air at a non-mixing rate that maintains stratification of air in the occupied space. An first exclusive return register is positioned near the ceiling and a second exclusive return register is positioned near the floor. A control system controls the flow of heated or cooled air to the supply register and selectively controls the flow of air into the first or second return registers. During the cooling mode, cooled air flows through the supply register and air is withdrawn only through the first exclusive return register, while in the heating mode warm air flows through the supply register and air is withdrawn only through the second return register.Type: GrantFiled: May 3, 2017Date of Patent: July 30, 2019Assignee: Oy Halton Group Ltd.Inventors: Andrey V.
