Abstract
A system and a method for operating an air handling unit (AHU) at an effective static pressure setpoint in a HVAC system. The method includes receiving airflow setpoint values from each of a plurality of variable air volume (VAV) units to determine a combined airflow set point for the plurality of VAV units of an air handling unit (AHU). The method also includes determining an effective static pressure setpoint for the AHU based on a relation between the combined airflow setpoint value and a static pressure represented by a system effect curve.
Claims22
A method comprising:
- receiving airflow setpoint values from each of a plurality of variable air volume (VAV) units to determine a combined airflow set point for the plurality of VAV units of an air handling unit (AHU);
- determining an effective static pressure setpoint for the AHU based on a relation between the combined airflow setpoint value and a static pressure represented by a system effect curve;
- and
- operating the AHU at the effective static pressure setpoint.
