PARAFFIN LATENT HEAT STORAGE MATERIAL COMPOSITION AND USE OF PARAFFIN COMPOSITION AS LATENT HEAT STORAGE MATERIAL

摘要

A paraffin-based latent heat storage material composition is provided which has a melting point close to the melting point of n-nonadecane and has a high latent heat of fusion equivalent to even-number normal paraffins. The present invention provides a paraffin-based latent heat storage material composition including n-eicosane, and n-octadecane and/or n-nonadecane. The paraffin-based latent heat storage material composition contains not less than 83% by mass of n-eicosane, not more than 13% by mass of n-octadecane, and not more than 17% by mass of n-nonadecane, and has a melting point lower than that of n-eicosane and latent heat of fusion of 230 J/g or more.
