Description

Technical Field

[0001] The present invention relates to the technical field of energy-saving windows, and in particular to a solution-filled automatic-response energy-saving window. Background Art

[0002] With the deepening implementation of the national "dual carbon" strategy, vigorously developing new building energy-saving technologies to reduce building energy consumption has become a key step in achieving carbon neutrality in the construction sector. Windows (or transparent building envelopes) have become a weak link in building energy consumption. For building windows, visible light energy in the solar spectrum can be used for indoor lighting year-round, while non-visible light energy benefits indoor heating in winter but significantly increases the building's cooling load in summer. Existing energy-saving windows, such as low-E windows, reduce summer cooling loads by reflecting infrared energy, but also significantly increase winter heating loads and lack dynamic adjustment capabilities. Given the inability of traditional windows to meet the differentiated needs of winter insulation and summer insulation, adaptive energy-saving windows with winter insulation and summer insulation are worth considering to dynamically adjust building cooling and heating loads.

[0003] Patent number CN108661503A discloses a composite energy-saving window based on a chemical solution heat storage device and an intelligent temperature control device. The window is provided with three layers of glass. Between the outer glass and the middle glass, a chemical solution heat storage device is provided. The temperature is adjusted by the volatilization and condensation of the solution. Between the middle glass and the inner glass, a thermal insulation film and a temperature control film are provided. Through intelligent control, the upper and lower rollers are driven to rotate. The thermal insulation section and light transmission section on the thermal insulation film are combined with the heat absorption section, heat reflection section and light transmission section on the temperature control film to realize the selection of four modes: light transmission mode, heat insulation mode, heat absorption mode and cold preservation mode, thereby realizing indoor light transmission and temperature control. The structure is relatively complex, the cost is high, and the service life of the components is short, which is not conducive to promotion and application. Summary of the Invention

[0004] The purpose of the present invention is to provide a solution-filled automatic response energy-saving window, which can achieve high-temperature heat insulation in summer and low-temperature heat preservation in winter, and has a relatively simple structure and low cost.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a solution-filled automatic response energy-saving window, including a window frame, on which three layers of high-transmittance glass are arranged from the outside to the inside, and an outer air interlayer and an inner air interlayer are formed between the three layers of high-transmittance glass; one of the air interlayers is filled with a copper sulfate solution, and the two air interlayers are connected by a micro peristaltic pump, which transfers the copper sulfate solution to any air interlayer by rotating clockwise or counterclockwise; a temperature detector is provided outside the window frame, and also includes a control device electrically connected to the temperature detector and the micro peristaltic pump respectively.

[0006] Preferably, the pipetting rate of the micro peristaltic pump is 100 - 500 ml / min.

[0007] Preferably, the copper sulfate solution has a mass concentration of 20%.

[0008] Preferably, the window frame forms a 90° angle with the high-transparency glass.

[0009] Beneficial effects:

[0010] In the present invention, by arranging three layers of high-transparency glass on the window frame to form an outer air interlayer and an inner air interlayer, and filling copper sulfate solution in one of the air interlayers, the micro peristaltic pump transfers the copper sulfate solution to any one of the air interlayers by rotating clockwise or counterclockwise. Utilizing the characteristic that the copper sulfate solution can transmit most of the energy in the visible light band for indoor natural light illumination, while significantly absorbing the energy in the non-visible light band. In summer, the copper sulfate solution is transferred to the outer air interlayer. When only the outer air interlayer is filled with the solution, the solution will absorb the energy in the non-visible light band and store this part of the heat in the solution. At this time, the temperature of the solution rises significantly and is higher than the outdoor air temperature. Due to the low heat conduction characteristic of the air in the inner air interlayer, the heat stored in the solution will transfer the energy to the outside through convective heat transfer, realizing the filtration of the non-visible light spectrum in summer and reducing the indoor cooling load. In winter, the copper sulfate solution is transferred to the inner air interlayer. When only the inner air interlayer is filled with the solution, the solution absorbs the energy in the non-visible light band and transfers this part of the energy to the indoor, realizing heat preservation in winter and reducing the indoor heating load.

The change or adjustment of its relative relationship, without substantial change in the technical content, should also be regarded as the scope in which the present invention can be implemented.

[0020] It should be noted that the parts not described in detail in this application are all prior arts.

[0021] As Figure 1 shown, a solution-filled automatic response energy-saving window includes a window frame 1. Three layers of high-transparency glass 2 are successively arranged on the window frame 1 from outside to inside, and the window frame 1 forms a 90° angle with the high-transparency glass 2. To improve the sealing performance of the solution, the three layers of high-transparency glass 2 are integrally formed by integrated melting or glued together.

[0022] An outer air interlayer 4 and an inner air interlayer 3 are formed between the three layers of high-transparency glass 2. A copper sulfate solution is filled in one of the air interlayers, and the copper sulfate solution has a mass concentration of 20%. Sandwich openings 6 are provided on the two air interlayers, and the two sandwich openings 6 are connected by a micro peristaltic pump 7. The micro peristaltic pump 7 transfers the copper sulfate solution to any one of the air interlayers by rotating clockwise or counterclockwise. The liquid transfer rate of the micro peristaltic pump 7 is 100 - 500 ml / min. A temperature detector 5 for detecting the outdoor temperature is provided outside the window frame 1, and a control device 8 electrically connected to the temperature detector 5 and the micro peristaltic pump 7 is also included. The working voltage of the micro peristaltic pump 7 is 12V, and this energy-saving window can be powered by an external power supply or a battery.

[0023] As Figures 2-4 shown, to achieve the dynamic regulation of building summer heat insulation and winter heat preservation, the present invention is realized through the following control:

[0024] Summer heat insulation mode: When the temperature detector 5 detects that the indoor temperature exceeds 30 °C, it transmits this signal to the control device 8. Subsequently, the control device 8 transmits a control command to the micro peristaltic pump 7, and through the diversion effect of the counterclockwise rotation of the micro peristaltic pump 7, the solution in the inner air interlayer 3 is transferred to the outer air interlayer 4. When only the outer air interlayer 4 is filled with the solution, the solution will absorb the energy in the non-visible light band and store this part of the heat in the solution. At this time, the temperature of the solution rises significantly and is higher than the outdoor air temperature. Due to the low heat conduction characteristics of the air in the inner air interlayer 3, the heat stored in the solution will transfer the energy to the outside through convective heat transfer, realizing the filtration of the non-visible light spectrum in summer and reducing the indoor cooling load.

[0025] Winter heat preservation mode: When the temperature detector 5 detects that the indoor temperature is lower than 15 °C, the signal transmission method is the same as that in the summer heat insulation mode, but the control device 8 transmits a clockwise rotation command to the micro peristaltic pump 7 to drive the solution in the outer air interlayer 4 to transfer to the inner air interlayer 3 close to it. When only the inner air interlayer 3 is filled with the solution, the solution absorbs the energy in the non-visible light band and transfers this part of the energy to the indoor, realizing winter heat preservation and reducing the indoor heating load.

[0026] Reference Figure 4 , provides the spectral transmittance of pure water and copper sulfate solution. Among them, the copper sulfate solution with a mass concentration of 20% can transmit most of the energy in the visible light band for indoor natural light illumination, and at the same time significantly absorb the energy in the non-visible light band.

[0027] The above is only a preferred embodiment of the present invention, and it is not a limitation to the present invention in any form. Although the present invention has been disclosed above with a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content within the scope of the technical solution of the present invention to make equivalent embodiments with equivalent changes.
