Thermal Efficiency of Counterflow Insulation Systems: Possible Applications

Source

In the last few years, papers have been presented on so-called dynamic or counter-flow insulation systems. These studies show significant reductions of thermal heat losses for such systems in comparison with “classic” insulation systems. Residential and industrial buildings using this technique already exist in Scandinavian countries and France. The aim of this study has been to obtain a better understanding of the actual efficiency of such systems.

After a brief reminder of the principle of this insulating technique, the authors present (1) a theoretical model by means of which values of thermal efficiency are derived, and (2) the experimental findings obtained under full-scale laboratory conditions. We then consider the limits and potential applications of dynamic systems.
