Embodiment 1

[0143] 66% SiO 2 , 2% Al 2 o 3 , 9% CaO, 4.5% MgO, 15% R 2 O, 0.6% Fe 2 o 3 , after mixing 0.01% CoO and 2.89% SnO evenly, input the evenly mixed material into the kiln head silo, enter the melting furnace through the feeder, melt the material into a liquid state at 1480-1600°C, and then put the liquid The material is shaped by a tin bath, annealed in an annealing kiln, and then cut into heat-absorbing glass.

Embodiment 2

[0145] 66% SiO 2 , 2% Al 2 o 3 , 9% CaO, 4.5% MgO, 15% R 2 O, 0.8% Fe 2 o 3 , 0.02% CoO and 3.89% SnO are evenly mixed, and the evenly mixed material is input into the kiln head bin, and enters the melting furnace through a feeder, and the material is melted into a liquid state at 1480-1600 ° C, and then the liquid state The material is shaped by a tin bath, annealed in an annealing kiln, and then cut into heat-absorbing glass.

Embodiment 3

[0147] The endothermic glass prepared in Example 1 was cleaned and placed in a magnetron sputtering instrument, and doped with 2.5% Al with ZnO 2 o 3 As a target, the working pressure is 0.1-8Pa, the distance between the target and the glass surface is kept at 15 cm, and the glass temperature is 120 degrees Celsius. The deposition rate is controlled at 20 nm / min, and the deposition thickness is at 800 nm. The prepared glass is GLSa1, which absorbs 80% at 300-380 nanometers, 30% at 380-760 nanometers, 85% at 760-2500 nanometers, and has a reflectivity of 92% at 3-100 microns.

Abstract

The invention discloses an intelligent glass system with an efficient one-way light and heat transfer function. The intelligent glass system comprises a sunlight efficient absorption functional layer,a blackbody radiation high-reflection functional layer arranged on one side of the sunlight efficient absorption functional layer, and one or more sunlight transmission layers arranged on the side, opposite to the sunlight efficient absorption functional layer, of the blackbody radiation high reflection functional layer.The area between the blackbody radiation high reflection functional layer andthesunlight transmission layers as well as the area between two adjacent sunlight transmission layers when the sunlight transmission layers are multiple areairtight hollow or vacuum heat convection suppression layers.

Description

technical field [0001] The invention belongs to the field of efficient and controllable utilization of solar energy building energy saving, and relates to a smart glass system with one-way transmission of light and heat. Background technique [0002] Energy saving and environmental protection are the themes of all mankind in the new century. The energy consumption of the building industry accounted for 26% of primary energy in 2006, and this figure is expected to rise to more than 30% by 2020. In hot and humid areas, the consumption of building energy consumption is more significant, accounting for about 1 / 3 to 1 / 2 of the country's total electricity. The annual electricity consumption per unit building area of ​​residential buildings is 10-20kwh, while the electricity consumption of public buildings is much higher, and the annual electricity consumption per unit building area can exceed 350kwh. 60% of building energy consumption is lost through glass doors and windows. ...
