Publication number: 20210310792Abstract: The present disclosure includes systems and methods for determining dimensions, shapes, and locations of rooms of a building using a mobile device for controlling heating, ventilation, and air conditioning (HVAC) provided to the rooms and building. A measuring device receives a shape of a room in the building and determines a dimension set of the room based on the shape of the room. The measuring device transmits the shape of the room and the dimension set to a mobile device that determines a layout of the building based on the shapes and the dimension sets corresponding to the rooms of the building. In this manner, the systems and methods provide the layout of the building more efficiently, resulting in an improved HVAC system installation and operation process.Type: ApplicationFiled: June 21, 2021Publication date: October 7, 2021Inventors: Shaun B. Atchison, Jedidiah O. Bentz, John W. Uerkvitz, Aneek M. Noor, Drew H. Carlton, Andrew M. Boyd, Brian D. Rigg, Shawn A. Hern, Noel A. Grajeda-Trevizo, Cody J. Kaiser, Tom R. Tasker

Patent number: 11022140Abstract: The present disclosure relates to a flow generating device for a heating, ventilation, and/or air conditioning system. The flow generating device includes a housing having a channel defining a flow path of a fluid and a fan blade having a rotational axis extending through the channel, where the fan blade is configured to rotate to force the fluid along the flow path. A portion of the fan blade axially protrudes beyond the channel in a direction generally aligned with the flow path and a winglet extends from the portion of the fan blade.Type: GrantFiled: September 12, 2018Date of Patent: June 1, 2021Assignee: Johnson Controls Technology CompanyInventors: Jordan R. Jensen, Tyler P. McCune, Drew H. Carlton, Bennie D. Hoyt

Patent number: 10837685Abstract: A heating, ventilation, and air conditioning system may include a refrigerant loop to circulate refrigerant, a first valve, a second valve, a sensor to measure parameters of the refrigerant, a refrigerant tank fluidly coupled to the refrigerant loop via the valves, and control circuitry communicatively coupled to the sensor, the first valve, and the second valve. The control circuitry may determine environmental conditions and detect whether an undercharge or overcharge condition is present in the refrigerant loop based at least in part on the environmental conditions and the measured parameters. The control circuitry may also instruct the first valve to open when the undercharge condition is detected to facilitate flowing refrigerant from the refrigerant tank into the refrigerant loop and instruct the second valve to open when the overcharge condition is detected to facilitate flowing refrigerant from the refrigerant loop into the refrigerant tank.Type: GrantFiled: July 24, 2018Date of Patent: November 17, 2020Assignee: Johnson Controls Technology CompanyInventors: Aneek M.

Patent number: 10830472Abstract: Systems and methods are disclosed that calibrate a defrost threshold used to determine when a heating, ventilating, and air conditioning (HVAC) system enters a defrost mode, and, more particularly, determine frost temperature differences used to determine the defrost threshold when the HVAC system is in a stable condition. A frost temperature difference is a difference between an outdoor ambient temperature and a refrigerant temperature. The HVAC system determines that it is in the stable condition by determining that a standard deviation of a current frost temperature difference from a previous frost temperature difference is below a standard deviation threshold. When the HVAC system is in the stable condition, the frost temperature differences are determined, and the defrost threshold is determined from the frost temperature differences.Type: GrantFiled: January 7, 2019Date of Patent: November 10, 2020Assignee: Johnson Controls Technology CompanyInventors: Shawn A.
