Information

This example validates Buildings.Controls.OBC.ASHRAE.G36.Plants.Chillers.Staging.Processes.Subsequences.UpEnd.

It shows how the staging up process ends when the process does not require one chiller to be enabled and another chiller to be disabled. The instance endUp shows the results as below. It stages up from stage 1 which requires chiller 1 to be enabled, to stage 2 which requires chiller 1 and chiller 2 to be enabled.

  • Before 1000 seconds, the plant is not in the staging up process (uStaUp=false).
  • At 1000 seconds, the plant starts staging up (uStaUp=true). However, it does not yet start the subprocess of ending the staging process (uEnaChiWatIsoVal=false).
  • At 1125 seconds, the ending process starts (uEnaChiWatIsoVal=true). The chiller 2 is enabled (yChi[2]=true). The ending process is done (the output yEndSta has a rising edge).
