It has been shown that a cool-storage material with superior performance property can be achieved from the mixed refrigerant hydrate, due to the principle of property compensation of mixtures. The experimelltal result reveals that HFC152a/HCFC141b mixed gas hydrate has an azeotropic melting property This means that mixed gas hydrates can has phaseequilibrium properties similar to that of mixture vapor-liquid phase equilibrium and it may be described by means of the solution theory. This discovery is significant for understanding the formation and phase change of mixed gas hydrates and improvement of gas-hydratethermal-energy-storage materials.展开更多
