Description

Technical Field

[0001] The utility model belongs to the technical field of glass curtain walls, and in particular relates to a novel hidden curtain wall circulating ventilation system. Background Art

[0002] The facades of common public buildings, high-rise and super-high-rise buildings, all have the contradiction between the opening of the exterior curtain wall windows and the overall aesthetic appearance. There are three common curtain wall ventilation systems: the first is the manually opened opening fan, which has the advantage of low cost and the disadvantage of a greater impact on the image, integrity and aesthetics of the facade; the second is the finished ventilation fan, which has the advantage of good concealment and the disadvantage of high cost, difficulty in cleaning and high maintenance cost; the third is the fully mechanical ventilation system, which has the advantage of a complete and beautiful exterior curtain wall system and the disadvantage of isolating the natural connection between the indoor and external natural air and relying on the operation of the ventilation system, which has a high cost.

[0003] In recent years, with the continuous development of curtain wall technology, various hidden opening fan methods have emerged. However, most hidden opening fans have a small opening range and poor ventilation effect in order to take into account the beauty of the facade.

[0004] To address the shortcomings of the existing technologies, researchers have conducted extensive research and proposed various solutions. For example, a Chinese patent document [201320597669.4] discloses a double-glazed curtain wall comprising an outer wall and an inner wall, wherein the inner wall is fixedly connected to the decking of each floor, a transverse partition is provided between the inner wall and the outer wall, and the partition is provided at the decking of each floor. An air inlet and an air outlet are provided on the outer wall of each layer of the glass curtain wall, wherein the air inlet is provided at the lower end of the outer wall of each layer of the glass curtain wall, and the air inlet is provided at the upper end of the outer wall of each layer of the glass curtain wall, and a ventilation shaft lateral vent is provided in the upper portion of each layer of the glass curtain wall.

[0005] The above solution solves the problem of high ventilation cost of existing curtain walls to a certain extent, but the solution still has many shortcomings. For example, its air inlet and outlet are both in the ventilation shaft and interconnected, resulting in a reduction in the air flowing into the glass curtain wall, affecting the ventilation effect.
