.Buildings.ThermalZones.Detailed.Examples.MixedAirFreeResponse

Information

This model illustrates the use of the room model Buildings.ThermalZones.Detailed.MixedAir.

The geometry, materials and constructions of the model are consistent with those of Buildings.Examples.VAVReheat.BaseClasses.Floor but here they are modeled as a single thermal zone. The model is representative for one floor of the new construction medium office building for Chicago, IL, as described in the set of DOE Commercial Building Benchmarks. There are four perimeter zones and one core zone. The envelope thermal properties meet ASHRAE Standard 90.1-2004.

For a comparison between the one-zone and five-zone model, see Buildings.ThermalZones.Detailed.Validation.SingleZoneFloorWithHeating.

Revisions

• April 10, 2020, by Michael Wetter:
  Changed room model geometry and construction material.
• October 29, 2016, by Michael Wetter:
  Changed example to place a state at the surface, and removed computation of the wet bulb temperature as it is not needed.
  Added thermal resistance of soil, because at the connector surf_conBou, there is now a state variable, and hence the temperature cannot be prescribed if its initial value is specified.
  This is for issue 565.
• March 26, 2015, by Michael Wetter:
  Set initialization of conOut to be steady-state initialization.
• February 12, 2015, by Michael Wetter:
  Set initial temperature to be 22°C to add propagation of the initial temperature to this test case.
• December 22, 2014 by Michael Wetter:
  Removed Modelica.Fluid.System to address issue #311.
• September 11, 2014, by Michael Wetter:
  Changed assignment of layers in conOut as layers is no longer replaceable.
• May 1, 2013, by Michael Wetter:
  Declared the parameter record to be a parameter, as declaring its elements to be parameters does not imply that the whole record has the variability of a parameter.
• December 14, 2010, by Michael Wetter:
  First implementation.
