Information

This example demonstrates how the model responses according to different cooling mode signals (free cooling mode, partially mechanical cooling and fully mechanical cooling).

The reponses are also compared with a second case where the PI controller in the WSE is reset every 1800s.

Revisions

• November 15, 2022, by Michael Wetter:
  Added missing assignment of pump record.
• May 13, 2021, by Michael Wetter:
  Changed boundary condition model to prescribed pressure rather than prescribed mass flow rate. Prescribing the mass flow rate caused unreasonably large pressure drop because the mass flow rate was forced through a closed valve.
  This is for #2488.
• January 28, 2019, by Yangyang Fu:
  Added test case for PI controller reset.
• January 12, 2019, by Michael Wetter:
  Removed wrong use of each.
• September 11, 2017, by Michael Wetter:
  Corrected wrong use of replaceable model in the base class.
  This is for issue 921.
• July 22, 2017, by Yangyang Fu:
  First implementation.
