Experimental study of heat storage in a PCM incorporated into a residentiel premises walls

To improve building energy efficiency, Phase change materials (PCM) can be applied in building envelope to conserve heat energy. The cubicle with PCM panels can automatically absorb indoor redundant heat, which can greatly reduce the load of Heating, Ventilation and Air-Conditioning (HVAC) systems and save electric energy. In experiments, a cell is constructed in the faculty of science Aïn Chock, at the Hassan II University of Casablanca (cavity with 3×3×3 m³). The internal side walls of the cell are covered by PCM panels. Thermocouples are erected above adequately to measure different temperatures used in the quantification of the thermal flux stored in the PCM or passing outwards. Determination of these fluxes is based on known correlations of the convective heat transfer coefficient. This latter which constitutes the main objective of our works, will be defined experimentally in future works.
