modelSimpleRoomTwoElementsNonConstantTGround

Illustrates the use of non-constant ground temperature for equivalent air temperature calculation

Extends from Modelica.Icons.Example (Icon for runnable examples), Buildings.ThermalZones.ReducedOrder.Examples.SimpleRoomTwoElements (Illustrates the use of a thermal zone with two heat conduction elements).

Information

This example shows the application of Buildings.ThermalZones.ReducedOrder.RC.TwoElements in connection with equivalent air temperature calculation in Buildings.ThermalZones.ReducedOrder.EquivalentAirTemperature.VDI6007WithWindow, where the ground temperature is not a constant, but has a trapezoid source. Apart from that, it is identical to Buildings.ThermalZones.ReducedOrder.Examples.SimpleRoomTwoElements.
