modelLocalDp_setpoint

Validate sequence of calculating local differential pressure setpoint

Information

This example validates Buildings.Controls.OBC.ASHRAE.G36.Plants.Chillers.Pumps.ChilledWater.Subsequences.LocalDp_setpoint.

It shows the process of specifying the local pressure setpoint for a primary-only plant, with one local pressure sensor and two remote pressure sensors.

  • After 1 second, the two remote pressure sensors have the measured values higher than the setpoint. The reverse acting PID controller thus gives the minimum output. The local pressure setpoint is at the minimum value (50000 Pa).
  • When the remote sensors have the measured values that become lower than the setpoint, their reverse acting PID controllers give the output greater than the minimum. The greater of the two output values from both PID controllers is picked for specifying the local pressure setpoint.
