Patent number: 11635222Abstract: A damper controller may be configured to send damper control commands to open and close an outdoor air damper to provide free cooling as necessary to satisfy a temperature setpoint inside the building. In some cases, the damper controller may initiate a damper fault test to determine if a damper fault is present. The damper fault test may be based, at least in part, on an outdoor air temperature input, a discharge air temperature input, a commanded damper position, and a damper fault temperature threshold. If a damper fault is determined, the damper controller may send an alert indicative of a detected damper fault. In some cases, the damper fault test results may be weighted to reduce the false positives alerts.Type: GrantFiled: June 9, 2021Date of Patent: April 25, 2023Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Lubos Sikora, Adrienne Thomle, Cory Grabinger, Miroslav Mikulica, Jan Prostejovsky

Patent number: 10935264Abstract: A system having a mixed air box with inputs of return air from a space or spaces of a building, and of outside air. The mixed air box may have an output of discharge air to the space or spaces of the building. The air from the output may be return air that is conditioned with cooling, heat, or outside air. A damper may be situated at the input of outside air to the mixed air box. A temperature sensor may be positioned at the input for outside air and at the output of discharge air. A cooling mechanism may be at the output of the discharge air. The temperature sensor may be downstream from the cooling mechanism. An economizer may have connections with the damper, the temperature sensor and the cooling mechanism.Type: GrantFiled: March 2, 2020Date of Patent: March 2, 2021Assignee: Honeywell International Inc.Inventors: Miroslav Mikulica, Cory Grabinger, Lubos Sikora, Adrienne Thomle, Jan Prostejovsky
