The invention relates to a thermal storage composition containing a phase transition material having a range of temperatures corresponding to the liquid - 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 - 5Ø 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 magnesium 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.

L'invention concerne une composition de stockage thermique contenant un matériau à changement de phase possédant une gamme de températures correspondant au changement de phase liquide solide qui est comprise entre 34 et 56 ·C et un modificateur de cristallisation se présentant dans les proportions suivantes, en pour cent en poids: pour le matériau à changement de phase 95 - 99,9; pour le modificateur de cristallisation 0,1 - 5,0. En tant que matériau à changement de phase, on peut utiliser différentes compositions possédant une gamme de températures correspondant au changement de phase liquide solide qui est comprise entre 34 et 56 ·C, par exemple, des mélanges de trihydrate d'acétate de sodium et de pentahydrate de thiosulfate de sodium, de trihydrate d'acétate de sodium et d'urée; un mélange d'hexahydrate de nitrate de magnésium, d'hexahydrate de chlorure de magnésium et de nitrate d'ammonium; un mélange d'acétamide et d'acétate de potassium, de nitrate d'ammonium ou d'urée; un mélange d'urée et de bromure de sodium, d'isothiocyanate de sodium, d'iodure de sodium et de nitrate de sodium. En tant que modificateur de cristallisation, on peut utiliser, par exemple, de la paraffine, de la gomme arabique, de la gélatine ou d'autres matières organiques possédant une action plastifiante ou gélifiante.
