NOVEL CLATHRATE FORMING MEDIUM AND ITS USE IN THERMAL ENERGY STORAGE SYSTEMS AND PROCESSES FOR THERMAL ENERGY STORAGE AND TRANSFER

摘要

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 ANGSTROM . Preferably the hydrofluorocarbon is selected from hydrofluoropropanes and more preferably is selected from the group consisting of CHF2CHFCHF2, CF2HCF2CH2F, CF3CHFCH2F, CF3CH2CF2H, CF3CF2CH3, CF3CHFCF2H, CF3CH2CF3, CF3CF2CF2H, CH2FCF2CF3, CHF2CF2CH3, CF3CF2CF2CH3, CF3CF2CF2CF2H, and CF3CFHCFHCF3.
