Potenzialanalyse der plasmabasierten, strukturierten Metallisierung thermoaktiver Oberflächen im industriellen Hausbau

Description

The industrial production of buildings offers a high potential for the creation of comparatively low-cost housing due to the high degree of automation and the resulting advantages, such as shorter construction times, lower demand for personnel and an increase in quality. However, currently the installation of the heating system is mainly carried out by manual methods, like in the construction of solid houses. In addition, the demand for material resources is partly very high.
The main subject of the research work was to develop a wall panel heating system that can be automatically integrated into the wall modules during the prefabrication process. The technical implementation of the requirements is an electrically operated wall panel heating system mounted directly on the surface of the building material. This was carried out using Cold Active Plasma Coating technology (CAPM), which allows the automated deposition of an electrically conductive structure on a variety of materials.
In a parameter study, a successful configuration was found for the production of electrically conductive structures using the CAPM process. The characterisation of the layered composite showed on the one hand that the copper particles form a permanent bond with the plasterboard surface, while on the other hand the functionality of the surface heating system could be proven on the basis of thermal tests. By investigating the electrical, thermal and mechanical properties of the panel heating system under defined environmental conditions, the long-term reliability of the wall panel heating system was successfully demonstrated. Using a comfort measurement method, an ideal thermal comfort of the heating system was objectively proven in a specially built demonstration house. Furthermore, the integration of the coating process into existing production lines for the manufacture of prefabricated houses could be confirmed within a theoretical investigation. The cost-effectiveness analysis shows the competitiveness of plasma-generated wall panel heating in relation to systems currently used on the market.
