The present invention belongs to the technical field of energy-saving lighting, and relates to an energy-saving lighting masonry module.
As an important strategic measure for national sustainable development, building energy saving is also the main content of building a resource-saving society, and has become an important task for construction workers in the field of construction. In the building maintenance structure, doors and windows, exterior walls, roofs and ground are four parts of building energy consumption.
1. Energy-Saving Measures for Windows
Doors and windows are the weakest link of thermal insulation and energy saving in the envelope structure. Therefore, an existing technical solution is to determine a reasonable window-to-wall ratio and use an energy-saving window. In various energy-saving windows produced in China, the energy-saving effect of double glass plastic windows is more significant.
To design high-performance energy-saving windows, the most important thing is to select and match the most reasonable window manufacturing solution in various glass technologies, so as to meet the requirements of energy-saving for the windows. Double-layer and multi-layer hollow glass and tinted coated glass are frequently-used selection modes. The material, form and air tightness of window frames also have a certain influence on the energy-saving effect.
2. Application Status of Light-Transmitting Concrete Technology
By implanting glass fibers into the concrete, the fibers between both sides are placed in parallel in a matrix. The glass fibers do not have any negative influence on the strength of the concrete. The current successful case of using translucent concrete in China is Italy Pavilion at the 2010 Shanghai World Expo. Exterior walls of the translucent concrete are used to solve the lighting problem in some pavilions.
3. Application Status of Glass Brick
Glass brick is a transparent and hollow small block with glass as base material, and is often used for decoration of non-load-bearing external walls, internal partition walls, lighting roofs and building partitions. In view of the research status and engineering application of the glass brick in China, most glass bricks are used for decorative materials, and a few glass bricks are used for building exterior walls.
1. Problems in Energy-Saving Technology of Windows
(1) Multi-layer glass can improve the thermal insulation performance of the glass. Although the heat transfer loss of the multi-layer glass is significantly reduced, the reduction of visible light transmittance and solar heat gain coefficient is not satisfactory.
(2) The gas filled in the middle of an interlayer can improve the energy-saving performance of laminated glass windows. Krypton and argon are two frequently-used inert gases that are non-toxic, colorless, tasteless and chemically stable. After the krypton gas is filled, the thermal insulation performance of the glass is better than that of the argon, but the cost of the krypton gas is higher. The gas always has the problem of leakage. Thus, the technology is very dependent on the sealing quality of the glass.
(3) In most commercial buildings, Low-E coatings are generally used to reduce solar heat gain. Although this is beneficial for supplementing heating, the solar heat gain is reduced. Because the coatings have a strong influence on the outside world, the coatings reflect sunlight as strongly as a mirror and affect nearby buildings.
(4) PASSIVE120 aluminum-plastic composite new energy-saving window has a main body of wood, and thus is still a wooden window, and inherently has a certain thermal insulation capability. A multi-chamber engineering plastic profile as an accessory is provided with 0.65 three glass two cavity double Low-E double warm edge filled argon hollow glass, so that thermal insulation coefficient K value is 0.8 W/(M2·K) and the thermal insulation effect is particularly prominent. When the thermal insulation coefficient K value of the energy-saving window is gradually reduced, if the K value is less than 1.8 W/(M2·K), the K value is gradually reduced. The reduction speed of energy consumption is not so obvious, but the invested capital is increased exponentially, which means that the cost performance is low and the energy-saving window cannot be popularized and applied.
2. Problems in Light-Transmitting Concrete Technology
There are still some obstacles to the mass production of translucent concrete in China. At present, the technology for such translucent concrete in China is not yet mature. The high cost of the light rays has intangibly increased the production cost. Large-scale use is still unrealistic. Restricted by the technology and price, such translucent concrete is only used in a very small amount in China, and is only used for the decoration of interior finish. At present, Chinese scholars are still studying and experimenting various mechanics of translucent concrete blocks, and their performance is still under test. The application range is relatively narrow compared with foreign countries.
3. Problems in Glass Brick Technology
Although glass brick masonry walls can achieve the lighting effect, the thermal insulation effect is still inferior to that of concrete blocks, which is not conducive to thermal insulation and energy saving. Moreover, the glass brick masonry shall be supported by the load-bearing wall or frame structure.
