Background

At present, the building energy consumption accounts for about 30 percent of the total social energy consumption, and becomes three major aspects of the energy consumption of China together with industrial energy consumption and traffic energy consumption. The energy dissipated through building maintenance structures such as doors, windows, walls and the like accounts for most of the building energy consumption, and is more than 50%. The door and window is an important component of a building maintenance structure, although the door and window occupies a small area in the maintenance structure, the door and window is the part with most active heat exchange and heat conduction of the building, and the heat loss caused by the door and window is 5-6 times of that of a wall body. Therefore, the development and the use of the energy-saving door and window are important ways for reducing the energy consumption of the building.

The heat loss caused by the door and window mainly has the following aspects: 1. loss through door and window sash materials and glass conduction; 2. radiation heat loss of the sash material and the glass; 3. air convection heat loss caused by door and window gaps. For the loss of the conduction through the door and window frame sash materials and glass, the solution is to use the materials with low heat transfer coefficient by improving the structural design of the door and window frame sash. The method of coating glass can reduce heat loss caused by radiation. In addition, the use of the sun-shading system is a more effective and simple way.

At present, research and development of door and window materials with low heat transfer coefficients and door and window structures have been advanced to a certain extent, the application range of coated glass and a sun-shading system is also expanded, the sealing performance between a wall body and a door and window frame material is also greatly improved, however, for a sliding window, the air tightness between a window sash and a window frame is not effectively improved all the time, and the problem of influencing building energy conservation is still solved.

The most widely used door and window types at present are mainly casement windows and sliding windows. The casement window sash and the window frame do not slide relatively, so that the air tightness is better than that of a sliding window. Meanwhile, the sliding window is widely adopted by various buildings by virtue of the advantages of convenience in opening, wide visual field, no indoor space occupation and the like. However, as energy saving standards in various regions are continuously improved, the requirements for the outer window are more strict.
