Mur intelligent pour un bâtiment économe en énergie par incorporation de composants thermoélectriques.

Intelligent wall for an energy efficient building by embedding thermoelectrics.

Numéro : pap. 3368



A building wall embedded thermoelectric device was investigated for energy efficiency of actively controlling heat the flow through in steady-state. The thermoelectric works to change the interior wall temperature by changing the applied electrical power or even switching the polarity. Although its moderate coefficient-of-performance (COP) due to the limitation from the thermoelectric material properties, the low-profile and flat structure of the thermoelectric heat pump provide an advantage to be built-in the walls. Based on electro-thermal energy transport model, a series of parametric design was performed and a couple of special cases of a hot day in summer and cold day in winter are illustrated. Design for the maximum heat transport or maximum COP are significantly different. According to the analysis results, the maximum COP of the intelligent wall was approximately 1.1 – 1.4 and the maximum heat pumping was around 50 W/m2 for the given climate conditions. Partial segment-by-segment operation of the actively controller wall will be further intelligent by sensing the wall temperatures with a real-time control of applied power considering thermal mass (time response) of the wall.
