The research project lays the foundation for the development of a highly efficient and cost-effective ventilation system with heat recovery. By combining fans and heat exchangers in a single component, the system can be designed to be very compact and is therefore particularly suitable for widespread use in building refurbishment. The aim is to improve the limited thermal efficiency of comparable systems currently available on the market from <50% to over 80% through an innovative concept and at the same time to significantly reduce the investment and operating costs through integrated components for balance, frost protection, sound insulation and summer bypass as well as moisture recovery. The simple but effective design with a low number of parts makes it suitable for the future industrial mass market.
