Experimental Study on the Thermal Performance of Paraffin Mixtures Used in the Phase Change Wall

摘要：

In this paper,the phase change temperatures,phase change latent heats and the stability of several kinds of paraffin mixtures were studied experimentally by differential scanning calorimeter (DSC).Experimental materials included n-Heptadecane,n-Octadecane,nEicosane,46# paraffin,48# paraffin and liquid paraffin.The experimental results show that the phase change temperatures and latent heat of paraffin mixtures change with their different compositions.Paraffin mixtures in different mass proportions have a wider phase change temperature range and higher phase change latent heat.So the paraffin mixtures can be used in different thermal storage fields by adjusting the proportion of each compositon.Several paraffin mixtures with appropriate phase change temperatures and higher phase change latent heat were given,and they can be used for thermal storage in building the wall.The results in this paper can provide references and basis for the application of phase change material wall.
