Cooling effect of PCM inserted in the walls: non linear phenomenon analysis

摘要

In order to show the efficiency of Phase Change Materials (PCM) in building walls we have used the software CODYMUR. The aim of the simulation is to evaluate the optimal thickness of the material and its behavior for different speeds of temperature evolutions in the room. The conclusion deals with the behavior of the wall due to the phase change phenomenon with a non linear thermophysical properties in comparison with a pure sensible storage layer.
