Description

Technical Field

[0001] The invention belongs to the technical field of energy-saving buildings, and in particular relates to an adjustable energy-saving skylight system suitable for tall and large spaces in cold regions. Background Art

[0002] In cold regions, tall and large-space buildings (such as factories, stadiums, exhibition centers, etc.) often face problems such as high winter heating energy consumption, prominent conflicts between natural lighting and sunshade, and insufficient wind and snow resistance of the enclosure structure. Traditional skylights mostly use fixed light-transmitting materials or mechanical sunshade devices, which have the following defects:

[0003] The light transmittance is not adjustable: For example, conventional ETFE air pillows adjust the shading coefficient by the amount of inflation, but the adjustment range is limited and the response is delayed;

[0004] High energy dependence: Photovoltaic skylights require maintenance ports, resulting in loss of power generation capacity, and rely on external power grids when light in cold regions is unstable;

[0005] Insufficient structural stability: The existing air pillow membrane structure is prone to deformation under extreme wind and snow loads, affecting the sealing and thermal insulation performance;

[0006] Poor photothermal synergy: It is impossible to optimize lighting, power generation and indoor thermal environment at the same time. For example, strong sunlight at noon can easily cause glare and overheating.

[0007] Therefore, extremely cold regions now need an intelligent skylight system that integrates dynamic light transmission adjustment, multi-energy complementary energy supply and highly stable structure. Summary of the invention

[0008] In summary, the present invention proposes an adjustable energy-saving skylight system suitable for tall and large spaces in cold regions to solve the deficiencies of the prior art.

[0009] An adjustable energy-saving skylight system suitable for tall and large spaces in cold regions:

[0010] The adjustable energy-saving skylight system is composed of a core light-transmitting module, an air-filling control module, an energy-complementary module, a snow-melting collection module, and an intelligent control module;

[0011] The core light-transmitting module is a three-layer air pillow structure with adjustable light fixed in an aluminum fixing frame, and a double-layer air cavity is formed by heat-sealing the edges.

[0012] The PTFE upper film material is a transparent film material, and the ETFE middle film material and the ETFE lower film material are ETFE films with staggered patterns and bottoms. The inflation volume is changed by the inflation control module, thereby changing the separation degree of the middle and lower ETFE films, thereby changing the coverage rate between the patterns and thus changing the amount of light entering.

[0013] The energy complementary module includes telescopic rods, pulleys, slide rails, photovoltaic glass and energy storage devices. The photovoltaic glass is located under the ETFE lower film material and can store electrical energy while generating electricity for indoor heating, and supply power to the inflation control module and the intelligent control module at night or in extreme weather conditions.

[0014] Furthermore, the light transmittance of the core light-transmitting module is 20%-100%.

[0015] Furthermore, in the three-layer ETFE air pillow structure of the core light-transmitting module, the PTFE upper membrane material has high durability and UV resistance, the ETFE middle membrane material has high light transmittance, and scatters light through patterned design, converting direct light into diffuse light to avoid light pollution; the ETFE lower membrane material has been treated with anti-condensation.

[0016] Furthermore, the inflation control module includes a circular tube for controlling compressed air, an inflation tube, an air compressor and an air storage tank, and monitors the air cavity pressure in real time and automatically compensates for air pressure loss through an intelligent control module.

[0017] Furthermore, the intelligent control module controls the energy complementary module to perform dual-axis tracking according to the solar altitude angle and azimuth angle, and aligns with the sun in real time.

[0018] Furthermore, the intelligent control module controls the angle of the photovoltaic glass and the inflation valve of the inflation control module in a linkage manner to maximize the power generation of the photovoltaic panel.

[0019] Furthermore, the snowmelt collection module includes a water trough with a slope of 5% and a hollow steel pipe for supporting and collecting water.

[0020] Beneficial effects of the present invention

[0021] The adjustable skylight proposed in the present invention solves the problem that the traditional skylight has a fixed light transmittance and cannot adapt to changes in light intensity during the day and night and between seasons. In summer, the heat radiation and glare can be reduced by adjusting the light transmittance of the inflatable structure, and the angle of the photovoltaic glass can be adjusted according to the solar altitude to enhance the intensity of photovoltaic power generation. In winter, the waste heat from the photovoltaic panels can be used to heat and melt snow, and the snow water can be collected.

[0022] The skylight designed by the present invention can reduce the heating and lighting energy consumption of tall and large-space buildings in extremely cold regions, improve the wind and snow resistance and air tightness of the skylight structure in extreme climates; build a complementary energy system, realize the coordinated control of light and heat, and reduce dependence on the external power grid.

[0023] The invention of the present invention has the advantages of being light, having strong space protection capability, being simple to implement, having low construction cost, being green, environmentally friendly and energy-saving. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The adjustable energy-saving skylight system is composed of a core light-transmitting module 1, an air-filling control module 2, an energy-complementary module 3, a snow-melting collection module 4 and an intelligent control module;

[0035] The core light-transmitting module 1 is a three-layer air pillow structure with adjustable light fixed in the aluminum fixing frame 1-4, and a double-layer air cavity is formed by heat-sealing the edges to increase durability and fire resistance. The light transmittance is 20%-100%.

[0036] The top PTFE membrane material 1-1 is a transparent membrane material. The top PTFE membrane has the function of anti-ultraviolet radiation, which can effectively block ultraviolet radiation from entering the room and protect indoor items from damage by ultraviolet radiation. At the same time, its fire protection grade reaches B1, which improves the safety of the system. The PTFE membrane structure has unique anti-aging and temperature resistance properties. It is not easy to fade and deform in the outdoor environment for a long time. It is mainly used in weather-resistant components in the construction field. Therefore, it is used in the top layer of the skylight to withstand the erosion of the external environment.

[0037] The lower two layers (ETFE middle layer film material 1-2 and ETFE lower layer film material 1-3) use ETFE film material with staggered pattern and bottom arrangement, which has high tensile strength, high tensile strength, good electrical performance, and better light transmittance. The inflation volume is changed by the inflation control module 2, thereby changing the separation degree of the lower two layers of ETFE film material, thereby changing the coverage rate between the patterns and thus changing the amount of light entering;

[0038] The middle and lower layers are made of ETFE membrane materials. The middle layer ETFE membrane has high light transmittance and scatters light through patterned design, converting direct light into diffuse light to avoid light pollution. The lower layer ETFE membrane has been treated with anti-condensation, and the hydrophilic coating on the surface can prevent water vapor from condensing into water droplets on the membrane, ensuring the light transmission effect and the dryness of the indoor environment.

[0039] The structural frame of the aluminum fixed frame 1-4 is rectangular and made of light metal pipes, which is easy to assemble. This makes the entire project convenient and easy from production, transportation, and assembly, reducing the cost of the project.

[0040] The energy complementary module includes a telescopic rod 3-1, a pulley 3-2, a slide rail 3-3, a photovoltaic glass 3-4 and an energy storage device. The photovoltaic glass 3-4 is located below the core light-transmitting module and can perform dual-axis tracking according to the solar altitude and azimuth. It can store electrical energy while generating photovoltaic power for indoor heating, and supply power to the inflation control module and the intelligent control module at night or in extreme weather conditions. In severe cold weather, it can melt the snow on the top layer of the membrane through thermal energy.

[0041] The inflation control module includes a circular tube 2-1 for controlling compressed air, an inflation tube 2-2, an air compressor and an air storage tank. The intelligent control module monitors the air cavity pressure in real time and automatically compensates for air pressure loss.

[0042] The snowmelt collection module includes a water tank 4-1 with a slope of 5% and a hollow steel pipe 4-2 for supporting and collecting water.

[0043] Example: Natural light passes through three layers of air pillows, is diffused by photovoltaic glass, reaches the surface of photovoltaic panels, and is converted into electrical energy;

[0044] Adjustments are made based on the daily changes in the solar altitude angle in the northern region, and the angle of the photovoltaic glass 3-4 and the inflation valve of the inflation control module are linked to control the maximum power generation. At the same time, sunlight can be converted into diffuse light through the ETFE transparent film and photovoltaic glass 3-4 to avoid light pollution.

[0045] Structural adjustment of three-layer air pillow:

[0046] (1) 6-11 am - maximum light transmittance, photovoltaic power generation intensity reaches the maximum, providing energy for indoor heating:

[0047] By adjusting the air supply system to 100% of the air volume, the light intake of the ETFE structure is 90%-100%;

[0048] (2) 11:00-15:00 noon - appropriate light penetration to ensure natural lighting and photovoltaic power generation, while avoiding indoor overheating and glare:

[0049] By adjusting the air supply system inflation volume by 60%, the light intake of the ETFE structure is 40%-60%;

[0050] (3) 15:00-18:00 in the evening - lower light transmittance to avoid sunset light pollution:

[0051] By adjusting the air supply system to a maximum of 30%, the amount of light entering the ETFE structure is 20-40%.

[0052] The above is a detailed introduction to the adjustable energy-saving skylight system suitable for tall and large spaces in cold areas proposed by the present invention, and the principles and implementation methods of the present invention are explained. The description of the above embodiments is only used to help understand the method of the present invention and its core idea; at the same time, for general technical personnel in this field, according to the idea of ​​the present invention, there will be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
