Information

This example tests the implementation of Buildings.Fluid.HeatExchangers.ActiveBeams.CoolingAndHeating for both heating and cooling mode. An air volume is maintained at a temperature between 22°C and 25°C by two controllers that regulate the water flow rate in the active beam.

    Replaced fluid source. This is for #1072.
  • June 25, 2016, by Michael Wetter:
    Changed medium start temperature to avoid conflicting start values of the same precedence in Dymola 2016. See issue 485.
  • June 14, 2016, by Michael Wetter:
    Revised implementation.
