Description

Technical Field

[0001] This invention belongs to the field of building energy-saving glass technology, specifically relating to intelligent thin insulating glass systems. Background Technology

[0002] The construction industry is increasingly demanding energy conservation, smart living, and lightweight structures. Insulating glass, as a core component of building envelopes, directly determines building energy consumption and occupant comfort. Existing insulating glass systems generally suffer from problems such as heavy structures, inability to dynamically control light transmittance, insufficient energy-saving limits, and weak environmental adaptability. Traditional insulating glass systems often use thick cavity structures to ensure thermal insulation, resulting in significant weight and increased load on the main building structure, making them unsuitable for high-rise buildings and high-load-bearing scenarios. While some smart insulating glass systems have light transmittance adjustment functions, their high tinting power consumption, poor heat transfer coefficient control, limited energy-saving effects, and delayed control response all contribute to their limitations. Furthermore, existing products are prone to performance degradation and limited service life under extreme environments such as high temperature and humidity, acid and alkali corrosion, due to cavity gas leakage and spacer aging.

[0003] To address the aforementioned shortcomings, existing technologies have not yet formed an integrated solution that combines lightweight structure, low-power intelligent control, high efficiency and energy saving, and strong weather resistance. This makes it difficult to meet the core requirements of green buildings for low-carbon operation and long-term stability. There is an urgent need for an intelligent thin insulating glass system to fill the technological gap in the industry. Summary of the Invention

[0004] The purpose of this invention is to solve the technical problems of existing insulated glass, such as its heavy weight, high energy consumption for intelligent control, limited energy-saving performance, and insufficient weather resistance. It provides an intelligent thin insulated glass system that achieves the unity of lightweight structure and high energy efficiency, and the compatibility of low-power intelligent control with extreme environment adaptability, providing long-term and stable building envelope material for green buildings.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a smart thin insulating glass system, comprising, from the outside to the inside, the following components arranged in sequence: double silver coated glass, a first insulating layer, an ultra-thin glass layer, a second insulating layer, a first tempered glass, a first PVB film, an EC electrochromic film, a second PVB film, and a second tempered glass;

[0006] Both the first hollow layer and the second hollow layer are filled with an argon-krypton mixture;

[0007] The edges of both the first hollow layer and the second hollow layer adopt an integrated composite sealing structure composed of heat-insulating spacers and high-performance sealant layers;

[0008] The EC electrochromic film is embedded with an intelligent adjustment component for driving the EC electrochromic film to change its light transmittance.

[0009] Using the above scheme, the nine-layer composite double hollow structure enhances heat insulation and sun protection performance through double silver-coated glass, the ultra-thin glass layer reduces the overall weight, the first and second hollow layers are filled with an argon-krypton mixture to improve heat insulation, and the first and second tempered glass ensures structural strength; the first and second PVB films achieve stable interlayer bonding and safety protection, and the EC electrochromic film serves as the core control component, working with intelligent adjustment components to achieve dynamic control of light transmittance; the integrated composite sealing structure effectively blocks water vapor and corrosive media, preventing gas leakage, and the overall structure achieves a unity of lightweight, intelligent control, high efficiency and energy saving, and strong weather resistance.

[0010] In a preferred embodiment, the thickness of the double silver coated glass is 4 mm, and the double silver coated glass adopts double silver Low-E coating.

[0011] Using the above solution, the double silver Low-E coating is selected with high light transmittance to enhance short-wave reflection and long-wave heat insulation effects. It works synergistically with the EC electrochromic film to double block heat transfer, further reducing the building's air conditioning load, while ensuring good light transmittance and taking into account both energy saving and natural lighting needs.

[0012] In a preferred embodiment, the thickness of both the first hollow layer and the second hollow layer is 8 mm, and the ratio of argon to krypton gas mixture is 7:3.

[0013] Using the above scheme, the first and second hollow layers with a thickness of 8mm provide ample space for gas insulation. The 7:3 ratio of argon to krypton gas mixture replaces the single inert gas. By utilizing the synergistic effect of the two gases in insulation, the heat transfer coefficient is significantly reduced. Combined with the double silver coating and EC electrochromic film, multiple high-efficiency heat insulation barriers are constructed, significantly improving energy-saving performance.

[0014] In a preferred embodiment, the thickness of the ultrathin glass layer is 1.5 mm.

[0015] By adopting the above solution, the 1.5mm ultra-thin glass layer significantly reduces the overall weight and the load on the main building structure while ensuring structural stability. It is suitable for high-rise buildings and high-load-bearing scenarios, and at the same time improves construction and installation efficiency.

[0016] In a preferred embodiment, the thickness of both the first tempered glass and the second tempered glass is 4 mm, and the bending strength is ≥150 MPa.

[0017] Using the above solution, the first and second tempered glass, with a thickness of 4mm and a bending strength of ≥150MPa, have excellent impact resistance and structural stability, effectively resisting external impacts. After breakage, no sharp fragments fall off. Combined with the bonding effect of the first and second PVB films, the system's safety protection level is improved, meeting building safety standards.

[0018] In a preferred embodiment, the thickness of both the first PVB film and the second PVB film is 0.76 mm, and the bonding strength is ≥2.5 N / mm².

[0019] Using the above solution, the first and second PVB films with a thickness of 0.76mm and a bonding strength of ≥2.5N / mm² can achieve a stable bond between the layers, avoid interlayer delamination, and have excellent weather resistance, anti-aging and anti-corrosion properties, making them suitable for extreme environments, extending the service life of the system, and ensuring the long-term stability of the overall structure.

[0020] In a preferred embodiment, the power consumption of the EC electrochromic film during coloring is less than 0.8W / ㎡, and the response time of the EC electrochromic film is ≤5s.

[0021] Using the above solution, the EC electrochromic film with a coloring power consumption of less than 0.8W / ㎡ significantly reduces energy consumption, which is far superior to existing smart glass products; the response time of ≤5s ensures timely control and can quickly adapt to changes in ambient light. While ensuring the balance of indoor and outdoor lighting, it can accurately reduce the operating load of the air conditioning system and improve energy utilization efficiency.

[0022] In a preferred embodiment, the intelligent adjustment component includes a distributed sensor, a controller, and a wiring module; the distributed sensor is used to collect ambient light intensity and temperature data; the controller controls the wiring module to apply a driving voltage to the EC electrochromic film 7 based on the data collected by the distributed sensor.

[0023] Using the above scheme, distributed sensors collect indoor and outdoor light intensity and temperature data in real time, providing a precise basis for regulation; the controller is equipped with a self-developed transmittance regulation algorithm, which can realize the dynamic adjustment of preset parameters or adaptive environmental changes. By applying an appropriate driving voltage to the EC electrochromic film through the wiring module, the coloring depth of the film layer is precisely controlled, ensuring the intelligent, precise and automated regulation.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] Employing a nine-layer integrated composite structure, double-silver-coated glass enhances heat insulation and sun protection performance, while the first and second tempered glass ensure structural strength. The first and second PVB films achieve stable interlayer bonding and safety protection, and the EC electrochromic film, as a core control component, is integrated into the middle layer. The overall structure retains the advantages of lightweight design while reducing the weight of traditional insulated glass by more than 25%, significantly reducing the load on the main building structure. This effectively solves the application limitations of high-rise buildings and high-load-bearing scenarios, and significantly improves the convenience of construction and installation.

[0026] With EC electrochromic film as the core, and integrating low-power adaptive adjustment components, the coloring power consumption of EC electrochromic film is strictly controlled within 0.8W / ㎡. Relying on self-developed transmittance control algorithm and light frequency control technology, it achieves precise and automated light control. Compared with existing smart glass, the energy efficiency is improved by more than 25%, filling the application gap of low-power smart glass in the building field. While ensuring the balance of indoor and outdoor natural light, it accurately reduces the operating load of air conditioning system.

[0027] Both the first and second hollow layers are filled with a customized ratio of argon-krypton gas mixture, replacing a single inert gas. Combined with high-quality thermal insulation spacer material and double-silver coated glass, they form multiple high-efficiency thermal insulation barriers. This keeps the system's heat transfer coefficient (K value) stably below 1.0 W / (㎡·K), improving energy-saving performance by more than 40% compared to traditional hollow glass with the same parameters. It is significantly superior to single-layer hollow structure products and makes it easier to achieve low-carbon goals during the building's operation.

[0028] Both the first and second hollow layers adopt an integrated composite sealing structure, combining the thermal insulation spacer with a high-performance sealing adhesive layer to form a multi-layer protective structure. This effectively blocks the intrusion of external moisture and corrosive media, and prevents the leakage of argon-krypton gas mixture. The first and second PVB films have excellent weather resistance and bonding stability, and can adapt to extreme environments such as high temperature and humidity, acid and alkali corrosion, avoiding interlayer peeling or performance degradation. Combined with the protective characteristics of double silver-coated glass and the first and second tempered glass, the product's service life is extended to more than twice that of traditional smart glass, significantly expanding the application scenarios of smart insulated glass.
