Patent number: 10782033Abstract: A heating control system that includes a heating unit with a constant burner and a pulsed burner. The constant burner is configured to remain active during operation. The pulsed burner is configured to toggle between an active mode and an inactive mode. The heating control system further includes a memory operable to store a temperature map that maps temperatures to percentages of a period that the pulsed burner is active and a microprocessor operably coupled to the heating unit and the memory. The microprocessor is configured to transmit a first electrical signal to activate the constant burner, obtain a temperature set point, determine the percentage of the period that the pulsed burner is active using the temperature set point and the temperature map, and transmit a second electrical signal to toggle the pulsed burner based on the determination of the percentage of the period that the pulsed burner is active.Type: GrantFiled: January 26, 2016Date of Patent: September 22, 2020Assignee: Lennox Industries Inc.Inventors: Eric M. Perez, Mark G. Beste, Steven Schneider

Patent number: 10775053Abstract: A heating control method includes determining a first speed for an air circulation fan that corresponds with a temperature set point using a temperature map that maps temperatures to speeds of the air circulation fan and operating the air circulation fan at the first speed and a heating unit in a first configuration with at least one active burner from a plurality of burners where less than all of the burners are active when the heating unit is in the first configuration. The method further includes measuring a first temperature while operating the air circulation fan at the first speed, determining a temperature difference between the first temperature and the temperature set point, comparing the temperature difference to a temperature difference threshold, and updating the temperature map to map the first speed to the first temperature when the temperature difference is greater than the temperature difference threshold.Type: GrantFiled: January 26, 2016Date of Patent: September 15, 2020Assignee: Lennox Industries Inc.Inventors: Eric M.

Patent number: 6945320Abstract: A tubular heat exchanger has at least one pair of dimples which are extruded into at least one tube of the heat exchanger by deforming the tube wall inwardly. The dimples of each pair are in generally facing relationship, but are offset with respect to each other along a longitudinal axis of the tube, which slows down the flow of flue gas in the tube when the heat exchanger is in operation and increases the turbulence of the gas, thereby enhancing the transfer of heat from the flue gas to air flowing across the outer surfaces of the heat exchanger. The offset design allows each dimple to protrude beyond the centerline of the tube, which alters the direction of the flue gas flowing in the tube.Type: GrantFiled: January 26, 2004Date of Patent: September 20, 2005Assignee: Lennox Manufacturing Inc.Inventors: Harold Gene Harvard, Jr., Steven Schneider, Eric M.
