[China Glass Net] 1. Thermal Conductivity of Aluminum Alloy Doors and Windows The thermal conductivity of aluminum alloy doors and windows generally refers to the heat energy transmitted by a certain unit area per unit time. The higher the thermal conductivity, the easier it is to conduct heat by the air. The indoor temperature is easily affected by the outside world. The thermal conductivity and material of the aluminum profile. It is related to the material composition, the composition of the alloy and even the design structure of the aluminum profile. 2, the degree of closure of aluminum alloy doors and windows The degree of closure of aluminum alloy doors and windows refers to how well the air entering is blocked when the aluminum alloy doors and windows are closed. The degree of sealing of aluminum alloy doors and windows has a great influence on heat transfer. The weather changes outside the house will have a certain impact on the temperature inside the house. If the degree of closure is high, the heat transferred will be less. The weather outside the house will affect the house. The temperature is even lower. 3. Area ratio of wall to door and window The ratio of the size of the door and window to the wall is also a very important thermal conductivity factor. Generally speaking, the thermal conductivity of the wall is much smaller than that of the aluminum alloy door and window. Therefore, the proportion of the door and window area is higher. Indoors are more susceptible to outdoor temperature, ensuring a reasonable proportion of door and window area under conditions of ventilation and light transmission, which plays a very important role in affecting heat conduction. 4, the orientation of aluminum alloy doors and windows The intensity of solar radiation and the irradiation time are different every day for 365 days a year. The solar radiation energy is transmitted to the doors and windows. The thermal insulation is the main meaning of energy saving for aluminum alloy doors and windows. In general, the insulation is improved. Thermal performance, improved door and window closure, well-designed doors and windows aluminum profiles, reasonable proportion of wall and window area, and the orientation of doors and windows. 5. Select reasonable energy-saving aluminum alloy doors and windows The type of doors and windows is very important for energy saving. Generally, the casement window and the fixed window have better energy saving effect than the sliding window. Because of the structural design of the sliding window, the lower part has a gap, which easily causes air flow. Therefore, it is easy to have an energy transfer process with the outside world. Therefore, because of the design problems, even if better materials are used, the energy saving effect is not good. Of course, some manufacturers have considered this problem and proposed many solutions. The method, for example, makes both sides of the guide rail high, and is made into a groove structure, which increases the difficulty of air flow. A sealing strip is added between the window of the casement window and the door frame. Then, after closing the door and window, the window automatically presses the sealing strip to greatly block the air, so the air flow is more difficult. Then the energy transfer is more in aluminum profiles and tempered glass. 6, fixed form Since the fixed window is installed in the wall as a whole, the glass is also installed in the window frame, and the glass and window frame are sealed with high-density glass glue to completely isolate the air flow, so the heat transfer is mainly the glass and the aluminum of the window frame.
