A type of exterior window without a sash and an outer frame

Abstract

The invention discloses an external window free of a window frame and an outer frame, and belongs to the technical field of building doors and windows. Currently, external windows of ordinary folk houses, hotels or office buildings have high energy consumption, and ventilation energy consumption of air windows mounted on facades is also high. According to the external window free of the window frame and the outer frame, conventional window frames and outer frames are omitted, support is provided by a steel frame and a window glass mounting frame both mounted outside the window, an upper heat-insulating plate, a lower heat-insulating plate, double-layer glass and a wall heat-insulating plate are used for separating the external window from the outdoor space, and accordingly, energy consumption of the external window is lowered; a ventilation opening formed in the lower heat-insulating plate is used for air exchange in winter, a ventilation opening formed in the upper heat-insulating plate is used for air exchange in summer, and ventilation energy consumption and dust entering indoors are reduced.

Description

technical field [0001] The invention relates to an outer window without a window frame and an outer frame, which is used for daylighting and exchange of indoor and outdoor air, and belongs to the technical field of building doors and windows. Background technique [0002] At present, the exterior windows of existing general dwelling houses, hotels or office buildings all have the following two deficiencies: [0003] 1. Conduction, convection, and radiation consume a lot of energy, especially in hot summer and cold winter areas. Although the area of ​​external windows accounts for a small area of ​​the building envelope, these three types of energy consumption of the external windows account for the energy consumption of the building envelope. More than 30% of the building envelope, and the area of ​​the outer window is still expanding year by year, so to improve the energy saving of the building envelope, the outer window is a very important part. [0004] 2. The energy con...

Problems solved by technology

[0003] 1. Conduction, convection, and radiation consume a lot of energy, especially in hot summer and cold winter regions. Although the area of ​​external windows accounts for a small area of ​​building envelope, these three types of energy consumption of external windows account for the energy consumption of building envelope. More than 30% of the total area, not to mention that the area of ​​the external window is still expanding year by year, so to improve the energy saving of the building envelope, the external window is a very important part

[0004] 2. The energy consumption of ventilation and infiltration is large. If the existing windows are opened for ventilation, the heat in the room is easily lost in winter and the air-conditioning in the room is easy to be lost in summer. This not only increases the energy consumption of cooling and heating and the fluctuation of indoor temperature. Excessive and uncontrollable ventilation also causes ventilation energy consumption accounting for more than 40% of the building envelope. At the same time, outdoor dust can easily enter the room too much, which is not conducive to environmental protection and hygiene.
