Dämmstoffintegrierte Kanäle für zentrale Lüftungsanlagen mit Wärmerückgewinnung

Integrated ventilation ducts in thermal insulation panels for heat recovery.

The energy-efficient renovation of existing buildings will among other things also play a key-role in achieving the climate-policy goals of the Federal Government by the year 2050. So far, however, the required number of modernized buildings remains far behind expectations, especially because of the high investment costs involved. The aim must, therefore, be to reduce the heating requirement of existing buildings as simply and cost-effectively as possible.
In the following an innovative product is presented which combines the functions of building insulation and ventilation in one component and thus allows the installation of controlled domestic ventilation systems with heat recovery without the usual problems of retrofitting air-ducts inside the building. In this new product, ventilation ducts are integrated directly in the usual commercially available insulating panels.
The function and processing of this novel system are illustrated and exemplified by demonstration objects. Not only are the energy-efficient, hygrothermal and acoustic characteristics of this system described in detail, but the fire protection and hygienic aspects are examined as well.
