On visualization of heat and vapour diffusion stream in three dimensional models

The difficulties in the depiction of the flow of heat and vapour through three-dimensionally modelled building constructions are taken up. A method well suited for practical use in finding regions which are critical with regard to heat and water vapour transport is presented. The pseudo colour image of the absolute values of the flow densities of heat and/or diffusion of water vapour immediately shows the regions of increased heat or vapour diffusion flow. Furthermore the plot of single flow lines clearly shows the three-dimensional path of the heat or water vapour through the building construction. The expressiveness of this method is demonstrated by an example representing a building construction which was analyzed by a three-dimensional calculation using the new thermal bridge program AnTherm.
