Internal and external double-circulating double-layer curtain wall

Abstract

The present invention relates to an internal and external double-circulation double-layer curtain wall. Every basic module of said curtain wall includes daylighting portion and ventilation device. The internal layer curtain wall bottom portion of said daylighting portion is equipped with air vent. It is characterized by that said ventilation device includes air intake mechanism and air exhaust mechanism, the air inlet of said air intake mechanism is communicated with outdoor space, and the air outlet of said air intake mechanism is positioned under the daylighting portion and is communicated with air spacing layer of daylightng portion, on the air inlet a stop valve is mounted; the air inlet of air exhaust mechanism is positioned over the daylighting portion and is communicated with air spacing layer of daylighting portion, the air outlet of air exhaust mechanism is communicated with outdoor space, on the air exhaust mechanism an air exhaust equipment is set.

Description

technical field [0001] The invention relates to a building external protection structure, that is, a double-layer curtain wall structure with internal and external circulation, specifically a double-layer curtain wall that can use two different ventilation methods to simultaneously realize the functions of the double-layer curtain wall of the internal circulation and the double-layer curtain wall of the external circulation curtain wall system. Background technique [0002] With the rapid development of China's economy and the acceleration of urbanization, building curtain walls have been more widely used. Especially with the promulgation of the national "Design Standards for Energy Conservation of Public Buildings", people pay more and more attention to the energy saving of buildings, and a large number of double-layer curtain wall structures are applied to the outer envelope of buildings. In the actual application process, the inner circulation double-layer curtain wall u...

AI Technical Summary

Problems solved by technology

However, due to the fact that the external circulation double-layer curtain wall is greatly affected by various factors in actual application, for example, due to the different conditions such as the orientation and form of the building, the design parameters and results of building ventilation will vary a lot; for different regions and different climates conditions, the structural design of the curtain wall has changed greatly, so that the performance of the curtain wall cannot be guaranteed

Moreover, due to the large thickness and size of the external circulation double-layer curtain wall, there are many components used, so the manufacturing cost of the curtain wall is relatively high, and the installation is also relatively complicated.
