Description

Low heat transfer window glass with blind The application discloses a divisional application of a patent application named 'low heat transfer window glass with a blind', wherein the application date of the original application is 2017, 11, 28 and 201711210914.0. Technical Field The invention relates to the technical field of window glass, in particular to low heat transfer window glass with a shutter. Background Along with the development of the building field, energy consumption is larger and larger, and heat dissipation of windows is a main way of energy consumption in buildings and is one of reasons for discomfort, so that energy-saving windows are widely focused, and particularly, multi-layer hollow glass windows are widely applied to the buildings. Wherein, the double-layer hollow glass (double glass for short) window is supported by using a spacer such as aluminum alloy, rubber, ethylene-propylene-diene monomer and other supporters around two glass plates, and then the periphery is sealed. Due to the existence of the cavity, the hollow glass has better heat insulation, noise insulation and other performances. However, as the requirements and standards of the state on energy conservation of buildings are higher and higher, the requirements of passive houses (energy consumption is lower than 85%) and zero-energy-consumption buildings (no energy consumption) are met, and further, higher requirements are put on the energy conservation of window glass. However, the existing double-glass or triple-glass window glass cannot meet the requirement, and the number of layers of glass is increased continuously, so that the load of a building is increased, and the stability of the building is affected. In addition, the existing window glass cannot realize the adjustable heat absorption or heat insulation effect, so that the heat transfer coefficient of the window is further reduced, the load of a building is not greatly increased, and the window glass with adjustable heat absorption or heat insulation to the window glass is met. Disclosure of Invention The invention aims to solve the problems that the heat transfer coefficient of window glass is reduced and the heat absorption or heat insulation of the window glass is adjustable without increasing the building load, and provides low heat transfer window glass with a blind.
