Aluminum Alloy Energy -saving Doors and Windows Are Selected by Aluminum Profiles and Glass! -Ruminum Profiles Supplier

According to research, industry, transportation and buildings account for one -third of the world's energy consumption. Building energy -saving technology should be divided into two major aspects: building enclosure structure and building auxiliary equipment. Building outer surrounding structure: heat insulation material, thermal insulation doors and windows. Architectural accessories: Solar heating, solar power supply, water/ground source heat pump, air -conditioning system energy saving, heating system climate compensation, time -sharing temperature and other hydropower energy -saving measures. The development of the energy consumption of the building mainly depends on the four major components of the wall, the ground, the roof, and the doors and windows, and the energy consumption of the doors and windows accounts for about 50 %.

Therefore, energy -saving doors and windows and new glass that can be effectively realized during use can be effectively realized during the use process, which can greatly reduce the fuel consumed due to heating and refrigeration, thereby reducing carbon emissions. With the gradual formulation and implementation of our national economic energy -saving technical policy system; the promotion of the performance logo of the energy saving work of building doors and windows; The era of energy -saving doors and windows is coming. Although the glass and window frames are not directly energy consumption, good thermal insulation and shading performance can greatly increase the energy consumption of building heating and refrigeration.

If the window glass is not selected well, the air -conditioning management system needs to be done well and cannot achieve the effect of improving energy -saving design. The so -called energy saving refers to the heat insulation, thermal insulation time, and through the light. The development of glass has a certain heat insulation and insulation, but the effects of different glass are not the same. The permeability of the glass is better. We can use the light during the day and use the sunlight, which is also a way to achieve energy saving. The doors and windows are one of the four major fence components of construction energy. It is the weak link of building insulation, heat insulation, and sound insulation.

Losses building energy by radiation, convection, conduction, and air penetration.

Therefore, the window is to improve indoor heat and the top priority of the light environment, which directly determines the energy saving effect of the building. Whether it is energy -saving of new buildings or energy -saving transformation of existing buildings, energy -saving windows are of great significance! In terms of heat transfer technology, because the development of aluminum alloy building materials in my country is a hot conductor, its thermal conductivity is 160w/m.k. In order to reduce the number of heat transfer of aluminum profiles, the heat guidance rate of PA88GF25 (PA88GF25 material is 0.3W/m.k) as the main economic ingredients, which divides aluminum alloy structural profiles into two important parts to break the break to break the break. The thermal guidance rate of different profiles of bridge aluminum alloy decreases significantly; at the same time, it consists of two independent space systems to form a closed air insulation layer to fully develop the insulation performance of the environment, making it the material and the overall thermal conduction rate to further pass the further pass through the passage. Reduce the heat transfer effect of aluminum alloy metal profiles from 6.9W/.k, which can be reduced to 3.0W/.k, or even lower to 1.0w/.k.k. According to statistics, under the condition of heating or air conditioning, the heat loss of single -fan glass windows in winter accounted for about 50 % of the heating load. In summer, the cooling volume consumes the cooling amount of about 30 air conditioning loads through single glass windows in summer. Reducing the energy consumption of doors and windows is an important part of improving the quality of indoor heat environment and an important part of improving the level of energy saving of the building.

Therefore, reducing solar radiation into the room, and reducing the temperature difference between windows or transparent curtain walls is a way to reduce the energy consumption of air conditioning. The main technical measures to improve the performance of the entire window

(1) Glass a. Changes in the structure of the glass: hollow rate, low radiation (low E) hollow glass. b. Change the different types of gas in the cavity: fill the inert gas. Because the inert gas is heavier than the air, it is not suitable to flow, and the number of heat transfer relationships is 0.2W/ k. c. Replace the hollow glass insulation film: aluminum insulation tablets, large thermal conductivity; heat insulation tablets, small thermal conductivity, improve the surface temperature of the glass edge, effectively reduce the surface exposure of the glass; reduce the heat transfer coefficient, the hollow glass can make the glass inside the glass in the glass The surface increases by 3 to 4 degrees, or the position temperature of the 75mm of the hollow glass is increased by 2 degrees and 4 degrees.

(2) Aluminum alloy profile Increases the heat -breaking distance of aluminum profile: Increases the width of the thermal insulation strip. Choose a good insulation framework: The framework is a weak link of another window thermal loss. The framework has a great impact on the performance of the entire window. The size of the changing cavity contour: the large empty cavity is divided into a small empty cavity in the insulating cavity.
