Abstract
The invention relates to the technical field of material application, in particular to an application device for energy storage and exchange by applying interconvertibility of a substance and a phase-change material thereof. The application device for energy storage and exchange by applying the interconvertibility of the substance is characterized in that an energy storage and exchange medium of an energy storage and exchange part is the phase-change material, and the phase-change material is a solid-liquid phase-change material. By virtue of the invention, the defect in the traditional application device for energy storage and exchange by taking oil as the medium is effectively overcome; and the phase-change material can be widely applied in the application device for energy storage and exchange.
Description
Technical field
The present invention relates to the material applied technical field, be specifically related to a kind of application apparatus and phase-change material thereof that utilizes the material interconvertibility to carry out energy storage exchange.
Background technology
At present, numerous energy stores in the switching equipment employed energy and stores exchange media and be generally oil; Have certain advantage though adopt oil to store exchange media, also exist long, defective such as volume is big of not high, the easy oxidation of storage temperature, not environmental protection, life-span as energy.
Phase-change material is to be studied a kind of environmental protection and energy saving material that is developed application after discovery, the seventies sixties in 20th century, also is a kind of energy storage material of cleaning.Phase-change material can absorb or emit a large amount of heats or cold from environment in the process of its undergoing phase transition, realize the conversion of energy in different time and space, keeps the temperature of self constant substantially simultaneously.Be widely used in fields such as HVAC, building, solar energy utilization, clothes, aspect energy-conservation, reduction of discharging, have great importance.
Therefore, novel phase-change material is applied to energy stores, exchange in the application apparatus, replacing existing is the application apparatus of exchange media with oil; It is the demand of technical development.
Summary of the invention
One of technical problem that the present invention solves is to provide a kind of energy to store the application apparatus of exchange; Be not that energy stores exchange media with oil; Have advantages such as storage temperature height, environmental protection.
Two of the technical problem that the present invention solves is to provide a kind of energy to store the phase-change material of exchange application apparatus, can effectively substitute oil and store exchange media as energy.
The technical scheme that the present invention one of solves the problems of the technologies described above is: a kind ofly utilize the material interconvertibility to carry out the application apparatus that energy stores exchange, mainly include energy and store switching part, applying portion, backflow part; Energy storage switching part, applying portion and backflow part link to each other in regular turn and form a loop; It is characterized in that: the energy storage exchange media that described energy stores switching part is a phase-change material.
Two the technical scheme that the present invention solves the problems of the technologies described above is: described phase-change material is a solid-liquid phase change material.
Described solid-liquid phase change material fusing point is the phase-change material below 400 ℃.
Described solid-liquid phase change material main component is a potassium nitrate.
Described solid-liquid phase change material main component is a potash.
The present invention utilizes solid-liquid phase change materials such as potassium nitrate, potash to replace oil to store, exchange storage, the exchange media of application apparatus as energy; Efficiently solve defectives such as oily oxidizing temperature is low; Make and adopt the application apparatus of the technology of the present invention to have:
1, storage temperature height adopts phase-change material of the present invention as medium, and minimum energy storage temperature can arrive 350 ℃; Than oily medium, temperature significantly improves.
2, environmental protection, the phase-change material that the present invention adopts is not easy to take place chemical reaction, and the acquisition that can circulate from refuse; Help reducing pollution to environment.
3, the life-span is long; The phase-change material cycle-index that the present invention adopts is many; Can effectively increase the service life.
4, volume is little; The phase-change material energy that the present invention adopts stores big, and to store required medium amount few in order to arrive energy with the oil phase equivalent, has effectively dwindled the volume of equipment.
The specific embodiment
Energy of the present invention stores the exchange application apparatus, mainly includes energy and stores switching part, applying portion, backflow part; Energy storage switching part, applying portion and backflow part link to each other in regular turn and form a loop; Storing switching part at energy is not that energy stores exchange media with oil; But adopt phase-change material is medium.Aforesaid phase-change material is a solid-liquid phase change material, and its fusing point is generally below 400 ℃.This solid-liquid phase change material main component can be the similar material of chemical characteristics such as potassium nitrate or potash, and sodium nitrate, silica; According to the demand of reality, can add flux regulating its fusing point, or add other compositions to regulate its proportion.
The preparation of aforementioned phase-change material or acquisition get final product according to existing preparation, acquisition methods; The requirement of uniqueness is not arranged among the present invention.
More than be the description to the specific embodiment of the invention, but the present invention also not only is confined to the aforesaid specific embodiment, all equivalences that can get according to aforementioned description change, and all belong to protection domain of the present invention.
