Box type ventilating double glass curtain wall having purification and dedusting function and purification and dedusting method thereof

Abstract

The invention discloses a box type ventilating double glass curtain wall having a purification and dedusting function and a purification and dedusting method thereof. The box type ventilating double glass curtain wall comprises an outer glass curtain wall and an inner glass curtain wall and further comprises a purification and dedusting device arranged in a thermal channel between the outer glass curtain wall and the inner glass curtain wall. Upper ventilating shutters of the inner glass curtain wall, lower ventilating shutters of the inner glass curtain wall, upper ventilating shutters of the outer glass curtain wall and lower ventilating shutters of the outer inner glass curtain wall are communicated with the thermal channel. The box type ventilating double glass curtain wall can purify outdoor fresh air and indoor circulating air, so that the goal of improving indoor air quality is achieved, a heat insulation effect of the curtain wall can be enhanced in winter and summer, and the goal of reducing building energy consumption is achieved.

Description

technical field [0001] The invention belongs to the technical field of building energy saving, in particular to a box-type ventilated double-layer glass curtain wall with the function of purification and dust removal. Background technique [0002] Due to the transparent and beautiful glass curtain wall, which has a distinct flavor of the times and technology, it has been increasingly popular in office buildings around the world since the second half of the last century. At the same time, there are endless doubts about the high energy consumption, light pollution, and poor ventilation brought about by glass curtain wall buildings. In order to make up for the shortcomings of traditional single-layer glass curtain wall buildings, in recent years, the ventilated double-layer glass curtain wall system has been introduced in China. The ventilated double-layer glass curtain wall structure is generally composed of two transparent enclosure structures. The air cavity as the air chan...

Problems solved by technology

However, it is obviously not environmentally friendly to directly introduce fresh air through natural ventilation under the existing outdoor air pollution conditions.

Patent 201120302397.1 (an energy-saving ventilation system for double-layer curtain walls) proposes that fresh air is sent into the room through double-layer glass curtain walls in cold seasons, and low-level cold air is introduced by curtain wall ventilators in hot seasons, part of which is used for external circulation to take away the surface heat of the curtain walls, and the other Part of it is introduced into the room as fresh air, but the problem is still that the introduced fresh air has not been purified. This will not only fail to improve the indoor air quality, but will aggravate indoor pollution, especially the pollution of particulate matter
