Description

A kind of energy-saving window
Technical field
The invention belongs to construction engineering technical field, specifically, being related to a kind of energy-saving window.
Background technology
Developed country's building energy consumption accounts for about the 33% of social total energy consumption.2000, the building energy consumption in China always disappeared in society Accounting in consumption is up to 27.6%.With the quickening of urbanization process and the improvement of people's living standard, building energy consumption is social total Accounting in consumption will be increased persistently, it is contemplated that will be eventually reached 35% or so.Therefore, building energy conservation has national economy great It influences.Door and window energy consumption accounts for the 50%~60% of building energy consumption, therefore obtains industry at present for the research in terms of energy saving door and window Great attention.
Existing energy saving door and window, generally using double-layer glass structure.It, can be in door when the requirement to door and window increases Increase low-emissivity coating on window and/or using modes such as three layers of reinforced structures.To summer it is sunny, it is indoor use air-conditioning system During cold cooling, in order to reduce the luminous energy got in, reduce energy consumption for cooling, need to carry out shading using curtain.
There is a kind of window to change colour according to temperature change in the prior art, darken when room temperature increases, play screening The effect of light achievees the effect that reduce energy consumption.It is electrochromic window to study at present more, and liquid is filled in window interlayer The functional materials such as crystalline substance, gel, when voltage changes, light transmittance changes.Such as Patent No. CN200580041480.5 " electrochromic compounds and associated media and device " patent disclose the compound used in electrochromism (EC) device; " the electrochromic window production method " of Patent No. CN201180057861.8 discloses the manufacturing method of electrochromic window. These technical solutions study electrochromic window, can realize energy-efficient technique effect, but these technical sides Case prepare energy-saving window it is complicated, increase multiple functions material, manufacture it is of high cost, it is difficult to large-scale promotion application.
Therefore, be badly in need of at present it is a kind of it is at low cost, simple in structure, being capable of the energy-saving window that uses of large-scale promotion.
Invention content
In order to overcome defect in the prior art, the present invention provides a kind of at low cost, the uses easy to spread of manufacture Energy-saving window.
According to an aspect of the present invention, a kind of energy-saving window is provided, the energy-saving window includes:Forms, phase change device And bracket;
The bracket is set to the lower part of the forms;
The forms are at least double-layer structure, and seal cavity is formed between at least two layers adjacent window material;The cavity In be packaged with liquid;
The phase change device is set in the cavity;
Solid-liquid phase change material is packaged in the phase change device.
A specific embodiment according to the present invention, the volume change of the phase change device and its internal solid liquid phase The volume change for becoming material is consistent.
Another embodiment according to the present invention adjusts material in the solid-liquid phase change material added with density Material;
The density modification material is used to adjust the density of the solid-liquid phase change material:
So that the density of the solid-liquid phase change material before phase change is more than the density of the liquid in the cavity,
So that the density after the solid-liquid phase change material phase transformation is less than the density of the liquid in the cavity.
Another specific embodiment according to the present invention is full of the solid-liquid phase change material in the phase change device.
It is laggard to encapsulate the solid-liquid phase change material in the phase change device for another specific embodiment according to the present invention Row vacuum processing.
Another specific embodiment according to the present invention, the energy-saving window includes multiple phase change devices, the multiple The different solid-liquid phase change material of phase transition temperature is packaged in phase change device.
Another specific embodiment according to the present invention, the transition temperature range of the solid-liquid phase change material 18 DEG C~ Between 30 DEG C.
Another specific embodiment according to the present invention, the transition temperature range of the solid-liquid phase change material 15 DEG C~ Between 35 DEG C.
Another specific embodiment according to the present invention is added with fungicide in the liquid.
Another specific embodiment according to the present invention is added with ornament and/or pigment in the liquid.
The solid-liquid density of most of materials is different or even differs greatly.For example, when water-setting build-ups ice, volume expansion 1/9, Canister even can be cracked.When preparing energy-saving window, the material of transformation temperature suitable (25 DEG C or so) is selected, is allowed to and window Liquid (below by taking water as an example) in the interlayer of family forms density contrast.When temperature is low, which is in solid-state, and density is more than Water, thus sink to the bottom;When the temperature rises, which is in liquid, and density becomes smaller, emerges.It is being embodied In the process, (for example, being scattered in curtain shape) is controlled with regard to that can play shading to the emersion form of phase-change material by special designing Effect.
After the present invention utilizes phase-change material before phase change the characteristics of volume change, variable density, it is applied to adjacent two layers Window is prepared between glass, realize it is energy saving, beautiful, manufacture it is at low cost, be easily installed the energy-saving window used.
