In numerous field of energy utilization such as solar thermal utilization, industrial afterheat recovery, heating and air-conditioning, in order to adjust inconsistent between heat energy supply and the actual demand, the storage of heat energy is the key link very.
The heat accumulation mode of generally using at present has two large classes: sensible heat formula heat accumulation and latent heat formula heat accumulation.The sensible heat accumulation of heat mainly is to store heat energy by the rising of certain material temperature or decline, the sensible heat accumulation of heat is that principle is the simplest in the various heat storage types, technology is the most ripe, material source is the abundantest, cost is cheapest a kind of, thereby also is practical application and to promote the most generally a kind of.The basic principle of latent heat formula heat accumulation institute foundation is that material is liquid (melting) by Solid State Transformation, changes gaseous state (gasification) into by liquid state, or by the solid-state gaseous state (distillation) that directly changes into, all can absorb the heat of transformation; Then discharge the heat of transformation when carrying out inverse process.Compare with sensible heat formula heat accumulation, latent heat formula heat accumulation has two large obviously advantages: storage density is large, namely can store a lot of heat energy with very little volume; Endothermic process and exothermic process almost are to carry out under constant temperature, are conducive to match with thermal source and load.
In the process of heat accumulation and heat release, certainly exist loss in efficiency.Especially later stage of heat accumulation process, because after the amount of stored heat of heat-storage medium is increased to a certain degree, and the later stage of exothermic process, because after the amount of stored heat of heat-storage medium reduces to a certain degree, heat transfer efficiency reduces, a part of heat can't exchange utilization in the heat-storing device, causes whole utilization ratio low.
Summary of the invention
The object of the invention is to for some the engineering difficult problems in sensible heat heat accumulation and the phase change material device, a kind of energy utilization rate height, steady, the reliable in structure of heat output are provided, parts are easy to make and install, and the combined phase change material device of integrated cost economy.
To achieve these goals, the invention provides a kind of combined phase change material device, wherein comprise heat storage can, researching of sensible heat storage material, phase-change thermal storage medium, phase-change thermal storage medium packaging body, described phase-change thermal storage medium-tight is loaded in the phase-change thermal storage medium packaging body, jointly realizes the process of heat accumulation or heat release with researching of sensible heat storage material.
Described phase-change thermal storage medium packaging body is sphere, cylinder or other geometry shapes.
Described researching of sensible heat storage material is the silicates solid material.
Described researching of sensible heat storage material directly contacts with working media.
Described researching of sensible heat storage material is that density is greater than the organic heat carrier oil of water.
Described researching of sensible heat storage material does not directly contact with working media, carries out the heat transmission by pipeline or heat exchanger plates.
Described heat storage can is made by metal material, and it is shaped as cylindrical shape or cube shaped, and its arrangement form can be vertical or horizontal.
Described heat storage can skin comprises insulation material.
The beneficial effect of the embodiment of the invention is: by phase-change thermal storage medium and researching of sensible heat storage material are used simultaneously, effectively utilize the heat accumulation exothermicity advantage of two media material, improve heat accumulation process and exothermic process the exchange heat amount, steady quantity of heat given up, thereby whole work efficiency and the reliability of raising heat-storing device.
