Shared parameterization of differential pressure set points in heating, ventilation, and air-conditioning systems

Abstract:

Method, apparatus and computer program product for managing a heating, ventilation, and air-conditioning (HVAC) system. In one example, a method includes obtaining a differential pressure reading from each differential pressure sensor of the plurality of differential pressure sensors; obtaining a differential pressure set point for each differential pressure sensor; applying a shared set point parameter to each differential pressure set point for a differential pressure sensor in order to generate a parameterized set point for the differential pressure sensor; for each differential pressure sensor, generating a demand indicator for the differential pressure sensor based on the differential pressure reading from the differential pressure sensor and the parameterized set point for the differential pressure sensor; and performing the supervisory control based on at least one demand indicator.
