Abstract-This paper discusses the development of a compartment
model for the simulation of thermal processes in a building
using the object-oriented programming standard Modelica. The
distribution of the temperature within a room is of special
interest. One of the main tasks in this work was the successful
realization of convection, since the Modelica modelling approach
doesn´t allow to actually model movement of air packages. Since
the walls, roof and floor of the building also have to be part
of the building model, this work starts with the description of
a solid compartment where heat transfer takes place only via
conduction. For the air compartment model, convection formulae
for even surfaces and polynomial regression for temperature
dependent parameters have been used to calculate the convectional
heat transfer coefficient for each compartment surface.
A comparison with a real experiment shows the validity of the
developed model. To further demonstrate the applicability of the
developed room model, an example with the inclusion of a DC
motor in the room model is shown.
