Optimum design of unit spacing for double glazing
Northeast China is located in the high latitude area of our country, the temperature is extremely low in winter, the indoor and outdoor temperature difference is very large, in order to meet the living requirements of residents in winter, it is necessary to carry out a good thermal insulation design for buildings. Among them, the thermal insulation performance of Windows is a very important link in building thermal insulation performance. And the glass design is particularly important in the composition of Windows, which is the key link of Windows' insulation performance.
Building doors and Windows is the weakest part of the insulation performance of the building's peripheral protective structure. Its long-term energy consumption accounts for about 50% of the long-term energy consumption of the whole building. Therefore, improving the insulation performance of Windows and doors is an important way to reduce the long-term energy consumption of buildings. The thermal insulation performance of Windows not only significantly affects the energy consumption of building heating, but also has a significant impact on indoor thermal environment, comfort and indoor sanitation. If the insulation quality of Windows is not good, the heat transfer loss through Windows and the heat loss through air penetration through window gaps will increase significantly, which will lead to a significant increase in heating energy consumption. At present, the widely used double layer glass unit is a kind of heat insulation, sound insulation, beautiful and applicable, and can reduce the building weight of the new building materials. This project aims to study the design scheme of double glazing unit spacing, and try to get the optimal spacing scheme that can achieve a high level of thermal insulation performance, and carry out experimental verification, so as to provide certain scientific references for the future design of building Windows thermal insulation in northeast China.
