Summary

Today emerge a true need to solve the problems of thermal mass in the buildings with light structures. A new product has been achieved by the DuPont de Nemours society: it is constituted with 60% of phase change material (PCM), for which the fusion temperature has been chosen to 22°C. This product is like a panel, relatively flexible, of 5 mm thickness. in order to show the efficiency of this PCM, we have lead a set of tests on the experimental cell: "MiniBat" of the CETHIL that represents 2 rooms of dwelling on a real scale (about 10 m2 by room) and of which one of the facades is oriented toward a climatic chamber reconstituting the outside conditions that one can make leisure vary. The tests have been achieved in a consecutive way while placing on the 3 non glazed walls a plate of insulating material. In a case the plates didn't contain a PCM and in the other, a panel of 5 mm of PCM has been inserted between the insulation in polystyrene and the interior plaster plate. The gap noted on the interior temperature was the order of 4°C for summery identical climatic conditions: cyclic evolutions of the outside temperature between 15 and 30°C and setting up of an artificial sunshine schedule acting on the glazed facade and reaching about 250 W/m2 on the vertical plan of the window.
