Abstract: front page image
(EN)An improved thermal energy storage system and a process for thermal energy storage and transfer are disclosed. The cooling medium, a clathrate forming mixture, comprises water, and a hydrofluorocarbon having at least carbon atoms and a molecular diameter less than about 7 Å. Preferably the hydrofluorocarbon is selected from hydrofluoropropanes and more preferably is selected from the group consisting of CHF¿2?CHFCHF¿2?, CF¿2?HCF¿2?CH¿2?F, CF¿3?CHFCH¿2?F, CF¿3?CH¿2?CF¿2?H, CF¿3?CF¿2?CH¿3?, CF¿3?CHFCF¿2?H, CF¿3?CH¿2?CF¿3?, CF¿3?CF¿2?CF¿2?H, CH¿2?FCF¿2?CF¿3?, CHF¿2?CF¿2?CH¿3?, CF¿3?CF¿2?CF¿2?CH¿3?, CF¿3?CF¿2?CF¿2?CF¿2?H, and CF¿3?CFHCFHCF¿3?.
(FR)Système amélioré d'accumulation d'énergie thermique et procédé d'accumulation et de transfert d'énergie thermique. Le milieu de refroidissement, un mélange de formation de clathrate, comprend de l'eau et un hydrofluorocarbone contenant au moins trois atomes de carbone et présentant un diamètre moléculaire inférieur à environ 7 Angstroms. L'hydrofluorocarbone est de préférence choisi parmi des hydrofluoropropanes et, idéalement, dans le groupe composé de CHF¿2?CHFCHF¿2?, CF¿2?HCF¿2?CH¿2?F, CF¿3?CHFCH¿2?F, CF¿3?CH¿2?CF¿2?H, CF¿3?CF¿2?CH¿3?, CF¿3?CHFCF¿2?H, CF¿3?CH¿2?CF¿3?, CF¿3?CF¿2?CF¿2?H, CH¿2?FCF¿2?CF¿3?, CHF¿2?CF¿2?CH¿3?, CF¿3?CF¿2?CF¿2?CH¿3?, CF¿3?CF¿2?CF¿2?CF¿2?H et CF¿3?CFHCFHCF¿3?.
