.AixLib.Examples.SimpleHouse

Information

This model contains a simple model of a house with a heating system, ventilation, and weather boundary conditions. It serves as a demonstration case of how the AixLib library can be used.

A step-by-step tutorial on how to build up this model can be found in AixLib.Examples.Tutorial.SimpleHouse. There are however some minor differences between this model and the models in the tutorial:

• Different numerical values are used for almost all model parameters.
• The solar irradiation (in W/m²) is calculated as the global horizontal irradiation multiplied with a solar heat gain coefficient instead of the direct normal irradiation.
• The ventilation system is equiped with a cooler that sets the temperature of the air flow entering the zone equal to a constant value of 20°C.
• The damper in the ventilation system is operated by a proportional-controller instead of a hysteresis controller.

Revisions

• September 15, 2023, by Jelger Jansen:
  Move the example model to AixLib.Examples, update the information section, and revise lay-out.
  This is for IBPSA, #1791.
• June 15, 2022, by Hongxiang Fu:
  Changed conDam.yMin from 0.1 to 0.25.
  This is for IBPSA, #1624.
• May 8, 2017, by Michael Wetter:
  Updated heater model.
  This is for IBPSA, #763.
• November 10, 2016, by Michael Wetter:
  Connected supply air temperature to outdoor air temperature, added cooling to supply air, changed capacity of heating system, switched heating pump off when heater is off, and added proportional controller for the air damper.
  This is for IBPSA, #584.
• September 9, 2016, by Michael Wetter:
  Corrected error in window model, as the solar heat gain was not multiplied with the window area. Dymola 2017 reported this error due to mismatching units of W/m2 and W.
• June 23, 2016, by Michael Wetter:
  Changed graphical annotation.
• March 11, 2016, by Michael Wetter:
  Corrected wrong limits for hysAir so that uLow < uHigh. This is for IBPSA, #429.
• January 22, 2016, by Michael Wetter:
  Corrected type declaration of pressure difference. This is for IBPSA, #404.
• September 19, 2015, by Filip Jorissen:
  First implementation.
