Heat Exchange Trough a Building Wall with an Air Layer Incorporating a Phase Change Material

摘要

The present work consists of a parametric study of a double wall separated by an air layer within PCM panels, exposed to solar radiation. This experimental study was conducted using two real-scale test cavities, located in the Faculty of Science Ain Chock - Casablanca, for active and passive cases. For this purpose, many thermocouples are used for the thermal control of indoor applications, as well as for measuring the temperature field of the air layer within PCM. The evolution of the measured temperatures will make it possible to calculate the heat fluxes densities exchanged through the walls to explore heat transfer inside the air layer with PCM. The results show that the temperature fluctuations. are reduced by 1.8°C for the internal face of the studied wall and by 1°C for the indoor temperature of the room with PCM compared to the reference room.
