modelTwoRooms
Thermal model of two rooms that will be linked to the BCVTB which models the controls
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
This example illustrates the use of Modelica with the Building Controls Virtual Test Bed.Given a control signal for two heat flow rates, Modelica simulates the thermal response of two first order systems. The two systems may represent a first order approximation of a room. The control signal for the heat flow rate is computed in the Building Controls Virtual Test Bed using a discrete time implementation of a proportional controller. Every 60 seconds, measured temperatures and control signals for the heat flow rates are exchanged between Dymola and the Building Controls Virtual Test Bed.
This model is implemented in bcvtb\examples\dymola-room.
