Abstract

The invention discloses a double-silver energy-saving glass of the sunlight selective filter film system, which is a glass substrate, a sunlight anti-reflection film system, a sunlight selective filter film system, a functional connection conversion film system, and a first visible light Transmission enhancing film system, first film layer adhesion enhancement film system, first single silver low-emissivity film system, second film layer adhesion enhancement film system, second visible light transmission enhancement film system, third film layer Adhesion-enhancing film system, second single silver low-emissivity film system, fourth film layer adhesion-enhancing film system, third visible light transmission enhancing film system, color modulation film system and surface covering film system. The invention has the advantages of simple structure, convenient use, energy saving and environmental protection, good human body comfort, and can selectively transmit visible light spectrum as required.

Description

technical field [0001] The invention relates to the field of energy-saving windows for buildings and vehicles, and in particular to a double-silver energy-saving glass of sunlight selective filter film system. Background technique [0002] With the rapid growth of my country's economy and the rapid development of society, about 2 billion square meters of new buildings are added every year. However, most of them are still high-energy buildings, and only 5% meet the energy-saving building requirements. Among the building energy consumption, heating and air conditioning energy consumption accounted for the largest proportion, accounting for about 60% to 70%. The energy consumption of heating and air conditioning is mainly consumed through the heat exchange between the building's peripheral structure and the outdoor environment. A large amount of coal is needed for heating in winter in the cold northern regions of my country, and a large amount of electric energy is required f...

AI Technical Summary

Problems solved by technology

In the hot summer of the whole country and the southern region, the traditional Low-E glass cannot selectively transmit sunlight, and because of the low transmittance, it can not only reduce energy consumption, but also make the interior of buildings and vehicles Excessive accumulation of heat in the interior will increase the large amount of electric energy required for air conditioning and cooling.

Furthermore, the over-thick metal film of traditional Low-E glass increases the reflection of visible light, and the overall transmittance in the visible light spectrum range is not high, which is easy to cause light pollution, and the outdoor reflection color does not meet the requirements of architectural design appearance. Design requirements

Equally, since the window glass of the vehicle does not have the function of saving energy, no matter in the cold winter or the hot summer, in order to keep the temperature in the vehicle comfortable, a large amount of fuel will be consumed, which also causes greater environmental pollution
