Abstract | |||||||||
| Developing energy-optimized ventilation strategies for moisture-related problems and the design and renovation of energy saving buildings requires an accurate knowledge of how hygrothermal components and buildings behave. These issues can be resolved with the aid of simulation tools before actually putting measurement technology into practice. The complexity of these issues produces complex models which can soon become unmanageable if suitable methods of description are not used. Due to their generic concepts such as class principle, inheritance principle, aggregation principle and polymorphism, modelling language standards such as Modelica enable complex systems such as these to be broken down into simple subsystems which can be verified and then reassembled. Research so far has lacked generic simulation tools for simulating components and buildings to enable a hygrothermal analysis with strong interactions between the behaviour of components, building envelope, building use and room conditions. Therefore the aim of this work was to develop a flexible, object-oriented, hygrothermal model library based on the Modelica modelling language for simulating and analysing the interactions between room conditions, the behaviour of components, building envelope and building use. This model library should be used for developing an energy-optimized ventilation system regulated according to demand in order to minimize the risk of mould forming while maintaining hygrothermal and hygienic comfort. The component and model library should be validated in example configurations in both simulations and trials. | |||||||||
