Part5: Choose to teach you to choose energy-saving glass
With the increase in the size of doors and windows of modern houses, the insulation requirements for doors and windows have also increased accordingly. In the summer, the role of energy-saving glass is more obvious. Let's take a look at the energy-efficient windows.
1. Introduction of energy-saving glass
Energy-saving glass has a special ability to absorb, transmit and reflect light and heat. It can provide significant energy-saving effects by using exterior windows and glass curtain walls of buildings. The energy-saving decorative glass commonly used in buildings has heat absorbing glass, heat reflecting glass and insulating glass.
2. Introduction of heat absorbing glass
The endothermic glass is a flat glass that absorbs a large amount of infrared radiant energy and maintains a high visible light transmittance. There are two ways to produce endothermic glass: one is to add a certain amount of colorant with endothermic properties to the raw material of ordinary soda lime silicate glass; the other is to spray one or more layers on the surface of flat glass. Made of metal or metal oxide film.
The heat absorbing glass is gray, brown, blue, green, bronze, bronze, pink and golden. There are four thicknesses of 2, 3, 5, and 6 mm. The endothermic glass can be further processed into a polished, tempered, laminated or insulating glass.
3. Introduction of heat reflective glass
Heat-reflecting glass is a flat glass with high heat-reflecting ability and good light transmission. It is coated with gold, silver and copper on the surface of the glass by pyrolysis, vacuum evaporation, cathode sputtering, etc. A metal or metal oxide film such as aluminum, chromium, nickel or iron, or an ion exchange method using an electro-floating method, which replaces the original ions of the surface layer of the glass with a metal ion to form a heat-reflecting film.
The heat reflection rate of the heat-reflecting glass is high. For example, the total reflection heat of the 6 mm thick float glass is only 16%. Under the same conditions, the total heat of reflection of the heat-absorbing glass is 40%, and the heat-reflecting glass can be as high as 61%. It is made of insulating glass or laminated glass to increase its thermal insulation properties. The metal-coated heat-reflecting glass also has the function of unidirectional through-image, that is, the outdoor scene can be seen indoors during the day, and the indoor scene is not seen outdoors.
4, hollow glass introduction
Insulating glass has a good thermal insulation capacity because it forms a gas layer of a certain thickness between two sheets of glass, and the flow of the intermediate air or other gas layer is restricted to reduce the convection and conduction heat transfer of the glass. At the same time, the single piece of insulating glass can also be coated with glass and other energy-saving glass, which can concentrate the advantages of these glasses on the insulating glass, thereby exerting a better energy-saving effect.
5, the choice of energy-saving glass
When choosing to use energy-saving glass, the glass type should be determined according to the geographical location of the building. The glass in the cold and cold areas should be controlled by heat conduction, and the insulating glass should be selected as much as possible; the solar hot summer cold area and the hot summer and warm winter area should control the solar energy as much as possible. Entering the room to reduce the air conditioning load, it is better to choose heat-reflecting glass, heat-absorbing glass and insulating glass and sun-shading insulating glass composed of heat-reflecting glass or heat-absorbing glass.
