SYSTEMS AND METHODS FOR DAMPER PERFORMANCE DIAGNOSTICS

摘要

A computerized method for diagnosing a damper condition in a flow control unit includes providing a control signal to a damper. The control signal instructs the damper to move into a target position or to achieve a target flow rate through the flow control unit. The method further includes receiving pressure information including one or more pressure measurements from a differential pressure sensor of the flow control unit and using the pressure information and the control signal to conduct a damper performance diagnostic. The damper performance diagnostic includes at least one of: a stuck damper diagnostic, a predictive damper failure diagnostic, an improperly-sized damper diagnostic, and a damper leakage diagnostic.

1. A computerized method for diagnosing a damper condition in a flow control unit, the method comprising:
providing a control signal to a damper, wherein the control signal instructs the damper to move into a target position or to achieve a target flow rate through the flow control unit; obtaining a differential pressure value using a measurement from a pressure sensor of the flow control unit; using the differential pressure value and the control signal to conduct a damper performance diagnostic process including at least one of: a stuck damper diagnostic process, a predictive damper failure diagnostic process, an improperly-sized damper diagnostic process, and a damper leakage diagnostic process; and outputting a result of the damper performance diagnostic process to at least one of: a user interface device, a local memory, and communications electronics.
