چکیده انگلیسی
Phase change materials (PCMs) inserted into walls and roofs of the premises; is one of the solutions to reduce the effect of external climatic conditions and energy consumption. This work is intended to compare the thermal behavior of two roofs types of local conditioned located in the cities of Casablanca and Ouarzazate. The first roof taken as a reference is constituted by the conventional building materials. In the second, two phase change materials are inserted in several combinations. The comparative study is performed using a numerical code developed and successfully validated. Comparison criterion between the reference roof and that provided with phase change materials is the annual heat flux density transmitted to the local conditioned. The simulation results show that insertion of phase change materials within the reference roof is favorable. The reduction of energy consumption in the room conditioned depends on the choice of the PCMs inserted and the temperature of the conditioned room.
