Description

Technical Field

[0001] This utility model relates to the field of building energy conservation technology, specifically to a window with added glass for energy conservation retrofitting. Background Technology

[0002] With global energy shortages and increasing environmental awareness, building energy conservation has become a crucial issue in contemporary social development. Among building energy consumption, the thermal performance of windows has a significant impact on building energy consumption. The single-pane windows widely used in traditional buildings, due to their simple structure and poor thermal insulation performance, are no longer sufficient to meet the requirements of modern building energy conservation and comfort.

[0003] Single-pane windows primarily rely on the material properties of the glass itself for heat and sound insulation, but their thermal performance is relatively poor, making them ineffective at preventing heat transfer. Especially during seasons with large temperature differences, single-pane windows can lead to significant heat loss from the interior or significant heat intrusion from the outside, thus increasing the building's heating and air conditioning energy consumption. Furthermore, single-pane windows offer limited noise insulation, failing to provide a sufficiently quiet and comfortable indoor environment.

[0004] The shortcomings of existing technology:

[0005] 1. Poor thermal insulation: Single-pane glass has poor thermal performance and cannot effectively prevent the exchange of heat between indoors and outdoors. In winter, indoor heat is easily lost, and in summer, outdoor heat is easily introduced, resulting in large fluctuations in indoor temperature and increasing energy consumption for heating and air conditioning.

[0006] 2. Poor sound insulation: Single-pane glass has limited sound insulation capabilities, especially for low-frequency noise, and cannot effectively block external noise, affecting the quietness and comfort of the indoor environment.

[0007] 3. Insufficient safety: Single-pane glass has poor impact resistance and wind pressure resistance, making it easy to break and posing a safety hazard. Once broken, glass shards may fly, causing injury to people and property inside the room.

[0008] Therefore, existing technologies have shortcomings and need further improvement. Utility Model Content

[0009] In view of the problems existing in the prior art, this utility model provides a window that has been retrofitted with glass for energy saving.

[0010] To achieve the above objectives, the specific solution of this utility model is as follows:

[0011] This utility model provides a window with added glass for energy-saving renovation, including:

[0012] An existing glass window includes a fixed frame, an operable window sash, and existing glass, wherein the existing glass is installed on the fixed frame or the operable window sash.

[0013] A flexible warm edge strip is continuously fitted to the entire circumference of the interior side of the existing glass;

[0014] The added glass is located on the indoor side of the existing glass, on the flexible warm edge strip, and parallel to the existing glass. The added glass and the existing glass form a sealed heat-insulating gas layer.

[0015] Silicone structural adhesive is used to fill the U-shaped joint formed by the fixed frame or operable window sash, existing glass, additional glass and flexible warm edge strip, to bond and fix the additional glass to the existing glass window. The U-shaped joint is an annular joint formed along the periphery of the existing glass and the additional glass, and its cross-section is U-shaped.

[0016] Furthermore, an EPDM adhesive strip is embedded between the fixed frame or the operable window sash and the existing glass.

[0017] Furthermore, the flexible warm edge strip has a ring-shaped closed structure and is made of silicone foam or composite polymer thermal insulation material.

[0018] Furthermore, the thickness of the sealed heat-insulating gas layer is 6–20 mm.

[0019] Furthermore, the laminated glass is of any of the following types:

[0020] Single-pane glass, double-glazed glass, vacuum glass, thermochromic glass.

[0021] Furthermore, when the added glass is insulated glass, its air cavity thickness is 9–16 mm.

[0022] Furthermore, the silicone structural adhesive is continuously injected into the U-shaped caulking joint to form a seamless sealing layer.

[0023] Furthermore, the outer contour area of ​​the added glass is equal to that of the existing glass.

[0024] Furthermore, the outdoor-facing surface of the attached glass is integrated with a transparent photovoltaic film layer, and a reserved channel is provided in the flexible warm edge strip. Conductive lines are threaded through the reserved channel to transmit electrical energy to the energy storage unit, thereby realizing energy storage.

[0025] The technical solution of this utility model has the following beneficial effects:

[0026] 1. Significantly improves thermal insulation performance: By adding glass to the interior side of existing glass to form a double-layer structure, the gas layer or thermal insulation layer between the two layers of glass effectively isolates the temperature difference between indoors and outdoors, reduces heat transfer efficiency, and greatly improves the thermal insulation effect. It solves the problem of easy heat exchange caused by the lack of an intermediate barrier layer in single-layer glass, which can more stably maintain the indoor temperature, reduce the energy consumption of air conditioning and heating equipment, and meet the energy-saving requirements.

[0027] 2. Improved overall thermal performance: In the double-layer structure, the gas layer between the existing glass and the added glass can effectively reduce the heat transfer coefficient (K value) of the light-transmitting enclosure structure. At the same time, the photothermal performance of the added glass (such as sun shading performance and visible light transmittance) further optimizes the overall thermal performance. Compared with the problem of single-layer glass having single and inefficient thermal performance, it can better meet the needs of improving energy-saving standards.

[0028] 3. Enhanced sound insulation: Double-glazed structures are far superior to single-glazed structures in blocking noise. Through the buffering effect of two layers of glass and the middle layer, noise transmission is effectively reduced, solving the problem of limited sound insulation and easy entry of outdoor noise into the room caused by the simple structure of single-glazed glass, thus improving the comfort of the indoor environment.

[0029] 4. Simple renovation with minimal impact on the original structure: This utility model uses silicone structural adhesive to fix and attach the glass without changing the connection between the existing glass window and the main structure, or adjusting the original EPDM adhesive strip. Compared with the complicated process of replacing or significantly renovating a single-layer glass if performance improvement is required, this significantly simplifies the energy-saving renovation steps, reduces construction difficulty and cost, and preserves the transparency of the existing structure.

[0030] 5. Wide range of applications: This double-layer structure renovation solution is not only suitable for ordinary single-layer glass windows, but can also be extended to existing glass curtain walls. It has strong versatility and can achieve a performance leap through simple installation in a variety of scenarios, solving the problem of poor adaptability of single-layer glass to energy-saving renovation in different application scenarios.

[0041] Combination Figures 1-4 As shown, this utility model provides a window with added glass for energy saving renovation, including:

[0042] An existing glass window includes a fixed frame 1, an operable window sash 2, and existing glass 3, wherein the existing glass 3 is mounted on the fixed frame 1 or the operable window sash 2.

[0043] The flexible warm edge strip 4 is continuously attached to the entire circumference of the interior side of the existing glass 3;

[0052] The silicone structural adhesive 6 is continuously applied within the U-shaped caulking joint to form a seamless sealing layer.

[0053] The outer contour area of ​​the added glass 5 is equal to that of the existing glass 3.

[0054] The outer surface of the attached glass 5 is integrated with a transparent photovoltaic film layer, and the flexible warm edge strip 4 has a reserved channel with a conductive line running through it for transmitting electrical energy to the energy storage unit to achieve energy storage.

[0055] The principle of this utility model is as follows:

[0056] 1. Insulation principle

[0057] The insulating effect of the gas layer: A closed gas layer (usually air or an inert gas) is formed between the panes of glass. The low thermal conductivity of the gas significantly reduces the rate of heat transfer through the glass. According to experimental data, the K-value of single-pane glass is typically around 5.7 W / (m²·K), while the K-value of double-pane glass can be reduced to 2.7-3.0 W / (m²·K). This gas layer effectively reduces heat exchange between the indoor and outdoor spaces, thus achieving the effect of keeping the room warm in winter and insulating it in summer.

[0058] The function of the flexible warm edge strip 4: The flexible warm edge strip 4 is installed around the perimeter of the existing glass 3 to support the additional glass 5 and form a seal with it. It not only enhances the stability of the double-glazed structure, but also reduces heat loss through the window frame and the contact edge of the glass, further improving the overall thermal insulation performance.

[0059] 2. Sound insulation principle

[0060] The sound insulation effect of double-glazed windows: Double-glazed windows use an air layer or inert gas layer between two panes of glass to block sound transmission. Sound is reflected and absorbed when traveling through different media; the gas in a double-glazed window reduces the speed and energy of sound propagation, making it particularly effective at isolating low-frequency noise (such as traffic noise). Experiments show that double-glazed windows can improve sound insulation by approximately 30-40 decibels compared to single-glazed windows.

[0061] The auxiliary role of silicone structural adhesive 6: While fixing the added glass 5, silicone structural adhesive 6 also provides a certain degree of sound insulation. It fills the gap between the double-glazed windows and the window frame, reducing the possibility of sound transmission through the gap.

[0062] 3. Safety Principles

[0063] Impact resistance: The double-glazed structure consists of two layers of glass. Even if one layer of glass breaks due to external force, the other layer remains intact, preventing fragments from flying and thus protecting the safety of people and property inside the room.

[0064] Wind pressure resistance: The strength and stability of the double-glazed structure are superior to that of the single-glazed structure, enabling it to better withstand wind pressure and vibration. The combination of the flexible warm edge strip 4 and silicone structural adhesive 6 further enhances the overall structural stability, making it particularly suitable for high-rise buildings or areas with strong winds.

[0065] 4. Anti-condensation principle

[0066] Reducing the effect of temperature difference: Double-glazed windows have better thermal insulation performance, making the surface temperature of the indoor glass closer to the indoor air temperature, thereby reducing condensation caused by excessive temperature difference. The flexible warm edge strip also reduces heat loss from the glass edges to some extent, further reducing the risk of condensation.

[0067] 5. Lighting optimization principle

[0068] Variety of glass options: Adding glass allows for the selection of different performance types based on actual needs, such as low-emissivity coated glass and thermochromic glass. These types of glass optimize lighting, ensuring ample natural light enters the room while effectively filtering ultraviolet and infrared rays, reducing glare and overheating.

[0069] 6. Principles of Energy-Saving Retrofit

[0070] Non-destructive renovation: This utility model does not require replacing the entire window frame and operable sash. It only requires adding a layer of glass to the interior side of the existing glass 3 and fixing it with flexible edge strips 4 and silicone structural adhesive 6. This renovation method is simple to construct, has minimal impact on the original building structure, a short renovation period, and low cost.

[0071] Structural compatibility: This utility model is applicable to various types of existing glass windows and glass curtain walls, and can be flexibly applied to different architectural scenarios, thus having broad promotional value.

[0072] By comprehensively applying the above working principles, this utility model achieves efficient energy-saving renovation of existing glass windows, significantly improving the heat insulation, sound insulation, safety and light transmission performance of windows, while reducing renovation costs and construction difficulty.

[0073] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the protection scope of the present utility model.
