Double-layer ventilation curtain wall system

Abstract

The invention belongs to the technical field of curtain walls, and particularly relates to a double-layer ventilation curtain wall system. The double-layer ventilation curtain wall system comprises an inner curtain wall plate, an outer curtain wall plate and a connecting plate, wherein the inner curtain wall plate and the outer curtain wall plate are connected through the connecting plate; a partition plate is arranged between the inner curtain wall plate and the outer curtain wall plate; installing strips are arranged in the middles of the side surfaces of the opposite sides of the inner curtain wall plate and the partition plate; installing grooves are formed in the installing strips; fixing rods are fixedly connected to the middles of the installing grooves; adjusting rods are slidably connected to the two ends of each fixing rod; a pair of hinge rods designed in an X shape is hinged between the end parts of the adjusting rods; the insides of the fixing rods and the adjusting rods are of hollow structures and communicate with each other; the inside of the fixing rods is externally connected with a gas source; and the gas source intermittently introduces carbon dioxide gas into the fixing rod and pumps the carbon dioxide gas out of the fixing rods. The air inlet efficiency and the air exhaust efficiency can be improved, and the air flowing between the inner curtain wall plate and the outer curtain wall plate is improved, so that the heat dissipation effect of the curtain wall system is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of curtain walls, in particular to a double-layer ventilation curtain wall system. Background technique [0002] Double-layer curtain wall is also called hot passage curtain wall, breathing curtain wall, ventilated curtain wall, energy-saving curtain wall, etc. It is composed of two layers of facade structure inside and outside, forming an air buffer layer between indoor and outdoor, with air inlets in the lower part and air exhaust outlets in the upper part, which can control the flow of air in between. With the development of science and the continuous improvement of people's living standards, the current buildings have higher and higher requirements for curtain walls, and more attention has been paid to the ventilation and heat transfer of curtain walls. [0003] The function of the double-layer curtain wall is basically divided into two types: external circulation and internal circulation. The external ...

AI Technical Summary

Problems solved by technology

[0004] In order to make up for the deficiencies of the existing technology, solve the poor ventilation performance of the curtain wall in the prior art, the installation and maintenance of mechanical equipment is difficult when using mechanical devices for ventilation, the technical requirements and production costs are relatively large, and large noise is inevitably generated during mechanical operation and energy consumption loss, poor energy-saving effect and in severe weather such as strong wind and hail, the external curtain wall is subjected to a large force, which is prone to deformation, depression or even falling off. The present invention proposes a double-layer ventilated curtain wall system
