More Information
Summary:The invention relates to a thermal storage composition containing a phase transition material having a range of temperatures corresponding to the liqu id - solid phase transition ranging between 34 and 56 ~C and a crystallization modifier represented in the following proportions, in weight percent: phase transition material 95 - 99.9; and crystallization modifier 0.1 - 5.0. As a phase transition material, various compositions can be used having a temperatures range corresponding to the liquid - solid phase transition ranging between 34 and 56 ~C, for example, mixtures of sodium acetate trihydrate and of sodium thiosulfate pentahydrate, of sodium acetate trihydrate and urea; a mixture of magnesium nitrate hexahydrate and magnesiu m chloride hexahydrate and of ammonium nitrate; a mixture of acetamide and potassium acetate, of ammonium nitrate and of urea; a mixture of urea and sodium bromide, of sodium isothiocyanate, of sodium iodide and of sodium nitrate. As crystallization modifier, materials such as paraffin, gum arabic and gelatin can be used as well as other organic materials having a plasticizing or gelling action.
