Ventilation SystemsCopyright: © EBC
Our vision are future-oriented ventilation systems for optimal indoor climate.
Effective ventilation systems are required to ensure a good indoor climate. The necessary individual components for air treatment, conditioning, transport, and transfer to the usage zone are combined to form an overall ventilation system. These should work as energy-efficiently as possible, both individually and in combination.
Therefore, as a team, we develop forward-looking concepts for systems and their components. We see both the optimisation regarding their energy efficiency, the influence on comfort or on economic efficiency, and the optimal interaction as an overall system as our research goal. For this purpose, we apply various experimental and simulative methods.
We use energy simulations to optimise the interaction of the system components. Here, the focus lies on the analysis of longer time periods, from several days to year-round simulations. We model the system and its individual components with a higher degree of abstraction. We investigate the system solutions we develop experimentally in our own test rigs and field tests to evaluate and validate the abstracted models.
Detailed investigations of individual components require high-resolution experimental and numerical methods. We use numerical flow simulations (computational fluid dynamics, CFD for short) to investigate and optimise the room flow structures and flows in components as well as the resulting aeroacoustic emissions. Using laser-optical measurement methods such as Particle Image Velocimetry (PIV) and Laser Doppler Anemometry (LDA), we resolve flow fields in detail in experiments and can thus validate the flow simulations. Applying acoustic and thermal-hydraulic measurement methods, we can analyse and optimise the performance of components and systems.
