Information

This example demonstrates the use of IDEAS.Airflow.AHU.Adsolair58HeaCoi in a bigger system. Four buildings are heated using warm air from an Adsolair ventilation unit with a heating coil. Heat is provided by a furance. An external pump and three way valve control the supply mass flow rate towards the heating coil in the ventilation unit. The air flow rate of the individual buildings is controlled using VAVs. A PI controller is used to track the set point temperature.

Revisions

  • February 4, 2025, by Jelger Jansen:
    Added Modelica.Units. to one or multiple parameter(s) due to the removal of import in IDEAS/package.mo. See #1415 .
  • October 30, 2024, by Lucas Verleyen:
    Updates according to IBPSA.
    See #1383 (and IBPSA, #1926).
  • January 26, 2018, by Filip Jorissen:
    Modified example such that it more clearly illustrates all operation modes. See #751, #730, #729, #754.
  • January 26, 2018, by Filip Jorissen:
    Revised implementation such that both cooling and heating are required and thus tested. Avoiding chattering.
  • February 1, 2017, by Filip Jorissen:
    First implementation.
