Construction method for energy-saving modification of glass of existing glass curtain wall

Abstract

The invention relates to a construction method for energy-saving modification of glass of an existing glass curtain wall. The construction method is characterized by comprising the steps that A, staff and equipment are placed to the required place through a basket; B, the to-be-modified glass of the existing glass curtain wall is cleaned and dried; C, a glass curtain wall paintjet is mounted; and D, temperature sensitive allochroic printing ink or ink is sprayed on the outer surface of the curtain wall glass. The invention further provides the glass curtain wall paintjet for realizing the construction method. The construction method has the beneficial effects that firstly, the influence on the glass of the existing glass curtain wall is small; secondly, due to the fact that the glass of the existing glass curtain wall is used, the modification cost is low; thirdly, the effect is good, specifically, the printing ink or ink containing vanadium dioxide is sprayed to the outer surface of the glass curtain wall, and the glass curtain wall can be modified into a fully intelligent energy-saving glass system having the equivalent activity external sunshading function; and fourthly, the reliability is good, specifically, the outer wall printing ink or ink is sprayed on the glass, bubbles are avoided, color is uniform, and durability is achieved.

Description

technical field [0001] The invention relates to a construction method for energy-saving transformation of glass in existing glass curtain walls, and belongs to the technical field of building energy conservation. Background technique [0002] At present, among the approximately 17 billion square meters of glass curtain walls in China, 93% are high-energy glass curtain walls. The heating and cooling energy consumption per unit area of ​​glass curtain walls is more than three times that of newly built glass curtain walls in developed countries. According to calculations, if we do not adopt effective energy-saving renovations and pay no attention to the energy-saving design of new glass curtain walls, our country's energy crisis will be directly aggravated. Therefore, the energy-saving transformation of the glass of the existing glass curtain wall is an objective requirement of my country's energy situation and an inevitable trend of market development. [0003] There are curr...

AI Technical Summary

Problems solved by technology

The problems are: 1. The construction of the film sticking is difficult. 2. The durability of the film attached to the outside of the curtain wall glass cannot meet the requirements. 3. The durability of the bonding between the film and the glass attached to the outside of the curtain wall glass cannot meet the requirements.

[0006] 3. Install vacuum glass on the inner side of the glass curtain wall: the heat transfer coefficient K value is ≤1.2, and the heat transfer coefficient is greatly improved, but the problems are: 1. The vacuum glass is expensive, 2. It affects the indoor structure

[0007] To sum up, there is currently no effective construction method for energy-saving transformation of glass in existing glass curtain walls
