Abstract

In this paper, a thermal resistance model for an energy wall using the example of thermo-active seal panels is presented. In the developed model, the resistances of the pipes as well as the resistance of the structure itself are considered. The resistance model is transferred to a 2D finite difference model, which itself is implemented into the general 3D subsurface heat and flow transport code SHEMAT-Suite. This coupling of a semi-analytical model with a numerical code avoids a complete discretisation of the model domain and thus enables fast computing times. This new approach has been verified by pure finite element simulations and by laboratory tests.

Acknowledgments

The development of the thermo-active seal panels was funded by the Federal Office for Building and Regional Planning (BBR) and was done in cooperation with the company NAUE GmbH & Co. KG. The development of the thermal resistance model is funded by the “Deutsche Bundesstiftung Umwelt” (DBU). The authors thanks all of them for the support.
