COMPOSITE HEAT-STORAGE MATERIAL

摘要

PURPOSE:To make it possible to control a plurality of temp. environments by fixing a plurality of latent heat-storage material in a granular material except one kind of them and covering this granular material with a film for preventing the latent heat-storage material from bleeding. CONSTITUTION:A composite heat-storage material comprising a latent heat- storage material (a)-1 consisting of Na2SO4.10H2O and a latent heat-storage material (b)-2 wherein a heat-storage pellet (b)-2 is infiltrated in a granular material 3 (e.g. a crosslinked PE) and a film 4 for preventing the heat-storage material from bleeding is formed on the surface of this granular material 3.
