Advanced HVAC modelling with FemLab/Simulink/MatLab.

Summary

The combined MatLab toolboxes FemLab and Simulink are evaluated as solvers for HVAC problems based on partial differential equations (PDEs). The FemLab software is designed to simulate systems of coupled PDEs, 1-D, 2-D or 3-D, nonlinear and time dependent. In order to show how the programme works, a complete code for solving a 2-D steady state heat transfer problem is given, along with results. A validation study of a 2-D dynamic airflow problem, modelled using Navier Stokes and buoyancy is shown. All results show good agreement with measurements. The use of Simulink is shortly discussed. Further advanced models include: a convective airflow around a convector, a thermal bridge model in FemLab connected to a room model and PI controller in Simulink and an indoor airflow model in FemLab connected to an on/off controller in Simulink.
