Patent number: 11739983Abstract: A method is provided for controlling combustion in a modulating gas furnace. The method includes receiving an indication of a firing rate setpoint for a burner assembly, and applying the firing rate setpoint to first and second continuous functions that map the firing rate setpoint to air-to-fuel ratio and combustion system pressure setpoints. A variable-speed draft inducer blower is set to drive to a combustion system pressure setpoint, and the modulating gas valve is controlled during combustion in the combustion system. In this regard, a combustion system pressure measurement is obtained and applied to an inverse of the first continuous function that outputs an adjusted firing rate for the combustion system pressure measurement. The adjusted firing rate is applied to a third continuous function that maps the firing rate to gas valve position, and outputs a gas valve position to which the modulating gas valve is set.Type: GrantFiled: September 17, 2020Date of Patent: August 29, 2023Assignee: Trane International Inc.Inventors: Youssef A Jaber, Wayne N Kraft

Patent number: 11536483Abstract: A method is provided for controlling an HVAC system. The method includes receiving zone airflow target values for zones of a conditioned space. The method includes accessing a duct model including a first term that describes a flow factor for a zone damper as a nonlinear function of damper position, and a second term that describes zone airflow as a function of the flow factor and a branch pressure across zone-specific branches of an air circulation path. The method includes applying the zone airflow target values to the duct model to determine a damper position set, and actuating zone dampers to respective damper positions of the damper position set. The method may also include determining a value of total airflow to achieve the zone airflow target values with a total pressure target, and causing a fan to provide conditioned air with the value of the total airflow.Type: GrantFiled: October 28, 2020Date of Patent: December 27, 2022Assignee: Trane International Inc.Inventors: Youssef A.
