Publication number: 20230383981Abstract: A heating, ventilating, and air conditioning (HVAC) system includes at least one indoor air quality monitor. The indoor air quality monitor is formed with an arrangement of chambers—intake chamber, low-flow chamber, and outlet chamber—such that a particulate sensor on an interior and another air quality sensor are neither overwhelmed nor underwhelmed by air flow to the sensors. The indoor air quality monitor may be arranged for attaching to a surface in a conditioned space for sampling air therein or may include a bypass chamber that fluidly couples to an HVAC duct. Other systems and methods are presented.Type: ApplicationFiled: May 31, 2022Publication date: November 30, 2023Inventors: Rajesh Alayil, Henry Todd Greist, Sanjeev Hingorani, Thomas John Wolowicz

Publication number: 20230383974Abstract: An indoor air quality monitor for an HVAC system includes a monitor body formed with a plurality of chambers defined at least in part by chamber walls. A bypass chamber allows for a majority of airflow entering the monitor to pass through. An intake chamber coupled to the bypass chamber allows for a portion of air to be removed for sampling by a particulate sensor. Air from the particulate sensor is discharged to an outlet chamber that is fluidly coupled to a downstream portion of the bypass chamber. The fluid requirements of the particulate sensor are maintained without overwhelming or underwhelming the particulate sensor. Other systems and monitors are presented; some include separate TVOC sensors.Type: ApplicationFiled: May 31, 2022Publication date: November 30, 2023Inventors: Rajesh Alayil, Henry Todd Greist, Sanjeev Hingorani, Thomas John Wolowicz

Publication number: 20230366581Abstract: An HVAC system includes one or more air quality sensors, each configured to measure an air quality and a thermostat communicatively coupled to the one or more air quality sensors. The thermostat receives indoor air quality measurements from the one or more air quality sensors. An indoor air quality score is determined based at least in part on the received indoor air quality measurements. The thermostat determines, based at least in part on the indoor air quality score, a mitigation action, wherein the mitigation action comprises one or more actions selected from the group of: (i) a filtering action comprising filtering air provided to the space using an air purification subsystem, and (ii) a ventilation action comprising ventilating the space using a ventilation subsystem. The mitigation action is executed, or implemented, by adjusting one or more components of the HVAC system.Type: ApplicationFiled: May 11, 2022Publication date: November 16, 2023Inventors: Sanjeev Hingorani, Henry Greist, Elena Smirnova, Pete Hrejsa, Emile Abi-Habib, Dhishan Kande

Patent number: 10518206Abstract: A method includes initiating, by a controller of a heating, ventilation, and air conditioning (“HVAC”) system, a filter calibration procedure, curve fitting a first line based on a plurality of static pressure measurements and corresponding flowrates of air, and generating a second line based on the first line. The method further includes determining a first static pressure measurement sensed by at least one sensor in response to determining that a first flowrate of air has been moved by the at least one blower and comparing the first static pressure value to a predicted static pressure value of the second line, the predicted static pressure value corresponding to the first flowrate of air. The method further includes determining that an air filter of the HVAC system has no more usable life in response to determining that the first static pressure value is greater than the predicted static pressure value.Type: GrantFiled: June 8, 2018Date of Patent: December 31, 2019Assignee: Lennox Industries Inc.Inventors: Sanjeev Hingorani, Henry Greist, Peter Hrejsa
