An energy-saving and noise-reducing window structure with real-time adjustable light transmittance and its optimization method

Abstract

The invention discloses an energy conservation and noise reduction window construction with real-time adjustable transparency and an optimization method thereof. The window construction is successively provided with a first glassy layer, a vacuum layer, a second glassy layer, a thin film dimming layer and a third glassy layer. The upper end of and the lower end of the five-layer structure are pressed to fit and are packaged through a U-shaped package frame. A light intensity sensor is disposed near the outside of the package frame of the first glassy layer. The light intensity sensor transforms a sensed light intensity signal into a current signal being sent to a coupler. Two electrodes are disposed on two ends of the thin film dimming layer. Lead-wires are introduced by two ends through the electrodes. The lead-wires are connected with an adjustable power supply. According to current signal strength, the coupler controls the input of the voltage of the adjustable power supply, so the transparency of the thin film dimming layer is adjusted in real time. The energy conservation and noise reduction window construction with real-time adjustable transparency has the advantages of simple assembly, low cost, real-time adjustment of the transparency of the window, great reduction of light pollution, obvious effect of sound insulation and noise reduction, energy conservation and environment protection.

Description

technical field [0001] The invention relates to the field of doors and windows, in particular to a window structure with real-time adjustable light transmittance. Background technique [0002] According to statistics, the current energy consumption of buildings in my country accounts for about 28% of the total energy consumption of the society. If the energy consumption of new buildings is not controlled, it is estimated that in 2030 it will exceed the energy consumption of industries and reach 10% of the total energy consumption of the whole society. About 40%, becoming the largest energy-consuming household in society. The window is the main way of building energy loss - about 30% to 50% of the energy is lost through the window. The situation in my country is particularly serious. Among the buildings of about 44 billion square meters, more than 85% use ordinary glass with poor thermal insulation performance and high energy consumption. The direct consequence is that the av...

Problems solved by technology

[0004] When the outdoor temperature is high and there is sufficient sunlight, the indoor temperature will rise rapidly through heat radiation and conduction with the window, resulting in a significant increase in energy consumption of indoor air conditioners

At the same time, when the outdoor temperature is low, the indoor heat will be lost to the outside through heat conduction and convection, resulting in increased energy consumption for indoor heating.

Generally, curtains can only block the energy exchange caused by radiation, but cannot shield the heat exchange caused by conduction.

The existing multi-layer door and window structure can only play a weak sound insulation and heat insulation effect, or only has a single function of dimming, and cannot adjust the light transmittance in real time, or the assembly structure is too complicated and the cost is high Not practical
