Integrated modeling of dynamic heat, air and moisture processes in buildings and systems using SimuLink and COMSOL

This paper presents an overview of the development and evaluation of integrated heat, air and moisture modeling using the SimuLink/COMSOL simulation environment for simulating dynamic heat, air and moisture processes in buildings and systems. Most of the models are successfully verified (by analytical solutions or by comparison with other simulation results) and/or validated (by experimental data). Overall it is concluded that the SimuLink/COMSOL simulation environment is capable of solving a large range of integrated heat, air and moisture problems. Furthermore, it seems promising in accurately solving modeling problems that are caused by the presence of different time scales and/or lumped/distributed parameters
