-September 15, 2023, by Jelger Jansen:
-Move the example model to IBPSA.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 #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 #429.
-

-January 22, 2016, by Michael Wetter:
-Corrected type declaration of pressure difference.
-This is

-First implementation.

-
-", info="
-
-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 IBPSA
library can be used.
-
-
-A step-by-step tutorial on how to build up this model can be found in
-
-IBPSA.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 (full) 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.

+
+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 IBPSA
library can be used.
+
+
+A step-by-step tutorial on how to build up this model can be found in
+
+IBPSA.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.
