Central external sunshade system

Abstract

The invention discloses a central external sunshade system. The central external sunshade system comprises an inner layer open glass window sash, an outer layer fixed glass window, and a sunshade curtain arranged between the inner layer open glass window sash and the outer layer fixed glass window. The inner layer open glass window sash, the outer layer fixed glass window and the sunshade curtainare mounted on a window frame. Inwards-opening sealing window sashes are arranged at the upper end and the lower end of the outer layer fixed glass window. The central external sunshade system is convenient to mount. Daily use and maintenance are convenient. The central external sunshade system is excellent in thermal performance. In summer, the central external sunshade system has the best effectof building external shading and can prevent conduction of thermal radiation into a room. In winter, full heat energy absorption is achieved in sunlight, and full heat preservation and energy savingare achieved without sunlight. The energy-saving requirements of green buildings are more reasonably and dynamically met. The sunshade, heat dissipation, heat absorption and thermal insulation properties of existing glass curtain walls and external windows are improved, and thermal performance of energy-saving buildings in China are enhanced and supplemented.

Description

technical field [0001] The invention relates to a central external sun-shading system, which can be directly applied to curtain walls or fixed external windows of various new and old buildings that require natural ventilation and sun-shading. Background technique [0002] At present, my country's requirements for green buildings and energy-saving buildings are becoming more and more stringent, and external sun shading is required for east-west external windows or glass curtain walls. However, for the architectural design of glass curtain walls, it will be serious if a large number of external sun shading Affect the aesthetic effect or facade form of the building facade; if the internal sunshade is used, the heat insulation effect is poor, and it is difficult to meet the requirements of green and energy-saving buildings; if the central sunshade is used, the internal sunshade is easy to age and difficult to maintain; for high-rise buildings For glass curtain walls and exterior w...

[0002] At present, my country's requirements for green buildings and energy-saving buildings are becoming more and more stringent, and external sun shading is required for east-west external windows or glass curtain walls. However, for the architectural design of glass curtain walls, it will be serious if a large number of external sun shading Affect the aesthetic effect or facade form of the building facade; if the internal sunshade is used, the heat insulation effect is poor, and it is difficult to meet the requirements of green and energy-saving buildings; if the central sunshade is used, the internal sunshade is easy to age and difficult to maintain; for high-rise buildings For glass curtain walls and exterior windows in buildings, there are more restrictive clauses in relevant regulations: such as restricting or not allowing outward opening, requirements for window opening area and window location, sun shading coefficient and solar energy collection and utilization requirements, etc.
