Especially in building renovation ventilation systems should be designed as compact as possible to avoid disturbing influences for users because they were not provided to be implemented in the original building design. Ventilation systems in which one component is responsible for ventilation and simultaneously for heat recovery are particularly suitable for this application area. Already existing systems like the HRCF (Heat Recovery Centrifugal Fan) have a systematically limited performance in ventilation and heat recovery efficiency.

The aim of this research project is to develop an innovative concept to increase ventilation and heat recovery efficiency. By creating a laboratory prototype the physical potential will be shown to enable the wide use in building modernization.
