  • Clathrate forming medium and its use in thermal energy storage systems and processes for thermal energy storage and transfer
    Patent number: 6079482
    Abstract: 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 three carbon atoms and a molecular diameter less than about 7 .ANG.. Preferably the hydrofluorocarbon is selected from hydrofluoropropanes and more preferably is selected from the group consisting of CHF.sub.2 CHFCHF.sub.2, CF.sub.2 HCF.sub.2 CH.sub.2 F, CF.sub.3 CHFCH.sub.2 F, CF.sub.3 CH.sub.2 CF.sub.2 H, CF.sub.3 CF.sub.2 CH.sub.3, CF.sub.3 CHFCF.sub.2 H, CF.sub.3 CH.sub.2 CF.sub.3, CF.sub.3 CF.sub.2 CF.sub.2 H, CH.sub.2 FCF.sub.2 CF.sub.3, CHF.sub.2 CF.sub.2 CH.sub.3, CF.sub.3 CF.sub.2 CF.sub.2 CH.sub.3, CF.sub.3 CF.sub.2 CF.sub.2 CF.sub.2 H, and CF.sub.3 CFHCFHCF.sub.3.
