摘      要：Phase change materials(PCMs)are an interesting technology due to their high density and isothermal behavior during phase *** change material plays a major role in the energy saving of the buildings,which is greatly aided by the incorporation of phase change material into building products such as bricks,cement,gypsum board,*** this study,an experiment has been conducted with three identical small chambers made up of normal,grooved and PCM-treated grooved *** the inclusion of PCM in grooved bricks,PCM material behavior has been studied by different techniques such as DSC,TG/DTA,SEM,and *** properties and thermal stability were investigated by differential scanning calorimeter(DSC)and thermogravimetric analyzer(TGA)*** electron microscopy(SEM)and X-ray diffraction(XRD)were used to determine the microstructure and crystalloid phase of the PCM before and after the accelerated thermal cycling test(0,60,120).These three identical model rooms built were exposed at a temperature just above 40°C with a *** the maximum outdoor temperature was 40-41°C,then the temperature of the PCM-treated grooved chamber was 32-33°*** PCM-treated wall was tested and compared with a conventional and grooved *** difference between the PCM-treated grooved chamber and the untreated one was 8-9°***-treated bricks provided more efficient internal heat retention in summer when the outside temperature increased.
