Energy-saving exterior window system with adjustable performance parameters

Abstract

The invention discloses an energy-saving exterior window system with adjustable performance parameters. The energy-saving exterior window system with the adjustable performance parameters is composedof an outer window and an inner window. The outer window comprises an upper window sash and a lower sliding window sash which are mounted in an outer window frame, and a semi-transparent amorphous silicon film battery sunshade roller shutter is mounted on the outer window frame. The inner window is an inner casement window, hollow glass is mounted on a window sash, and a low-radiation glass film is attached to one inner side face of the hollow glass. All window frames and window sashes are made of multi-cavity heat-insulation aluminum alloy profiles, the inner window frame and the inner windowsash are filled with aluminum foil-sealed phase-change energy-storage materials. According to the energy-saving exterior window system with the adjustable performance parameters, the solar heat gaincoefficient, the heat transfer coefficient and the working temperature range of the whole exterior window system can be adjusted through the outer window, the semi-transparent amorphous silicon film battery sunshade roller shutter, the low-radiation glass film and the phase-change energy-storage materials sealed in the inner window frame and the inner window sash, so that the overall heat-preservation performance and heat-insulation performance of the exterior window system are effectively improved, and the capability of the exterior window system to adapt to outside weather changes is comprehensively improved.

Description

technical field [0001] 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 [0002] 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 pa...

Problems solved by technology

But even so, the window frame of the exterior window is 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.
