Abstract

This paper deals with the thermal performances of PCM/diatomite composites for energy saving. The PCM/diatomite composites were prepared by incorporating PCMs in the pores of diatomite to increase form stability of PCMs. In experiment, we used the hexadecane, octadecane and paraffin as PCM and they have each 254.7 J/g, 247.6 J/g and 144.6 J/g of latent heat capacity, and those melting points are $20.84^{\circ}C$, $30.40^{\circ}C$ and $57.09^{\circ}C$, respectively. Thermal properties of PCM/diatomite composites were determined by using DSC. And PCM/diatomite composites were characterized by SEM and FTIR analysis. The results showed that the PCMs are well infiltrated into the structure of diatomite andt he latent heat capacity of PCM/diatomite composites was obtained by 40% of pure PCMs.
