Technical field
The present invention relates to a kind of Inorganic phase change energy storage material.
Background technology
Thermal storage and energy accumulation technology is widely used in renewable energy utilization and energy-saving field in recent years, and energy storage technology is
Through the strategic problem as energy security and sustainable development.In the method for numerous energy storage, the latent heat of solid-liquid phase change material
The features such as energy storage mode is due to its high latent heat high density and the phase transition temperature of relative constancy is widely used in air conditioner energy saving, the sun
Can utilize, the field such as Thermal Design of Electronic Equipments, building energy conservation.
Inorganic phase-change material it is both economical it is economical be crystalline hydrate salt, they have larger heat of solution and fixed
Fusing point, when the temperature increases, the crystalline hydrate salt abjection crystallization water make salt dissolving and heat absorbing, and inverse process occurs when the temperature decreases, inhales
Receive crystallization water heat release, crystalline hydrate salt with organic phase-change material compared with have thermal conductivity factor it is larger, density greatly and unit volume
The advantages of thermal storage density is high.
But to there is degree of supercooling big for the crystallization water, it is separated and the shortcomings of corrosivity, in order to reduce its degree of supercooling and suppress phase
The generation of segregation phenomenon, needing to add a certain amount of nucleator and thickener in actual applications is improved, in order to avoid phase
Separating the contingency question caused also needs to add suitable quantity of water progress integral material improvement.
In 0 ~ 120 °C of low temperature phase change humidity province, the unit volume enthalpy of phase change of crystalline hydrate salt is generally arrived 200
400MJ/m3, and barium hydroxide is found so far in this low-temperature phase popular form of narrative literature flourishing in the Tang Dynasty all area's unit volume enthalpy of phase change highests
(572MJ/m3)Crystalline inorganic hydrated salt.
Therefore need to provide a kind of Inorganic phase change energy storage material, can both reduce degree of supercooling, can also avoid being separated, carry
Height uses cycle-index, increases the service life, and this material can provide core material technology for the development in energy storage field, have
Very important meaning.
