Description

An energy-saving external window system with adjustable performance parameters

technical field

The invention relates to an energy-saving external window system with adjustable performance parameters, which belongs to the technical field of building energy saving and green building.

Background technique

Ultra-low energy consumption buildings are the only way to develop in the field of building energy conservation. my country promises and plans to reach the peak of carbon dioxide emissions around 2030. In order to achieve this ambitious goal, the national building energy conservation work is gradually moving towards the goal of ultra-low energy consumption, near zero energy consumption and net zero energy consumption buildings. In order to achieve the goal of ultra-low energy consumption buildings, the thermal insulation performance of building exterior windows in winter and summer should be greatly improved, which requires that building exterior windows should have a good ability to cope with climate change, that is, their performance parameters should be adjustable.

The energy-saving performance of building exterior windows includes thermal insulation performance, heat insulation performance and ventilation performance. The quality of these performances directly affects the thermal comfort of the building interior and the energy consumption of heating, ventilation and air conditioning throughout the year. There are five building climate thermal divisions in my country, which are severe cold area, cold area, hot summer and cold winter area, hot summer and warm winter area, and mild area. Different climate divisions have different requirements for the overall performance of building exterior windows. Emphasis on thermal insulation performance, hot summer and warm winter and mild regions pay attention to thermal insulation and ventilation performance, while hot summer and cold winter regions are relatively complex, which requires not only good thermal insulation performance of external windows, but also good thermal insulation performance and ventilation performance , so the relevant parameters of building exterior windows should have good adjustable performance. With people's continuous pursuit of high-quality life, the requirements for indoor comfort are getting higher and higher, and the requirements for the adjustability of building exterior windows will also meet higher requirements.

At present, the heat transfer coefficient, which is closely related to the thermal insulation performance of external windows in winter, is generally controlled below 1.6W/(m ² K) in northern severe cold regions, and below 2.0W/(m ² K) in cold regions, and is common in hot summer and cold winter regions. Below 2.2W/(m ² K), 3.0W/(m ² K) in hot summer and warm winter areas, and 3.2W/(m ² K) in mild areas. The shading coefficient of external windows in summer is mainly used to reduce the energy consumption of air conditioners, so it has attracted much attention in the south. For example, it is required to be below 0.45 in hot summer and cold winter regions, below 0.3 in hot summer and warm winter regions, and below 0.4 in mild regions. However, the building exterior windows currently on the market cannot meet these requirements at the same time.

In order to improve the thermal performance of the external window system, the window frames of the external windows currently adopt a multi-cavity structure, and the external windows using metal profiles are basically heat-insulated. But even so, the window frames of external windows are still the weak link of building energy conservation at present. There is still a certain risk of condensation in the cold northern winter and extreme climates, which will have a negative health impact on the vision and indoor environment.

Therefore, aiming at the development trend of ultra-low energy consumption, near-zero energy consumption and net-zero energy consumption in building energy-saving, combined with the high-quality demand brought by people's pursuit of a better life, research and develop building exterior window systems with adjustable performance parameters to improve Overall performance of exterior windows in existing buildings.
