To implement.
It should be appreciated that such as " having ", "comprising" and " comprising " term used herein do not allot one or many
The presence or addition of individual other elements or its combination.
The heat preservation principle of energy storage material is：Material melt or crystallize when, all can with heat absorption or release, example
Such as aqueous water can discharge substantial amounts of heat energy at 0 DEG C and transform into solid water (ice), and aqueous water at normal atmospheric pressure
A large amount of heat energy can be absorbed at 100 DEG C and transform into vaporous water (water vapour), but not all material can follow this
One rule, in actual crystallization process, most of materials temperature under liquid condition can not be immediately when being down to its crystallization temperature
Solid-state is changed into, its actual crystallization temperature is always less than theoretical crystallization temperature, and this phenomenon is referred to as surfusion, theory crystallization
The difference of temperature and actual crystallization temperature is referred to as degree of supercooling.
And some inorganic salts and water can form inorganic salt crystal in special ratios, but crystallization temperature is not yet found at present
The inorganic energy storage material for 20 DEG C or so is spent, and almost all of inorganic salts crystallizing system all has serious supercooling problem.
