The conventional curtain wall does not integrate a carbon sink function module, and the annual carbon fixation per unit area is less than 0.5 kg / m 2 . In view of the above problems, a solution is proposed as follows. Summary of the Invention

Detailed implementation manners

[0014] The following is only the preferred implementation manner of the present invention, and the protection scope is not limited to this embodiment. Any technical solution within the idea of the present invention shall fall within the protection scope of the present invention. The same components are denoted by the same reference numerals.

[0015] As Figures 1 to 3 shown, an intelligent constant-temperature ecological curtain wall system includes a gradient light-transmitting composite curtain wall 1, a multi-modal sensing array 7, a bionic ventilation mechanism 10 and a vertical green plant module 13. The first three are used to maintain the constant temperature of the curtain wall, and the vertical green plant module 13 is used to purify the air around the curtain wall.

[0016] The gradient light-transmitting composite curtain wall 1 includes LowE glass 2 and cadmium telluride thin-film photovoltaic glass 3. The cadmium telluride thin-film photovoltaic glass 3 is arranged in contact with the wall, and the LowE glass 2 is arranged on the outer side of the wall. The LowE glass 2 is inclined, and the inclination angle between it and the cadmium telluride thin-film photovoltaic glass 3 is 10 - 15°. Moreover, neither the upper end nor the lower end of the LowE glass 2 and the cadmium telluride thin-film photovoltaic glass 3 are in direct contact, and they are connected through a mounting plate fixed on the wall surface.

[0017] In this design, the inclination direction of the LowE glass 2 is inclined obliquely upward, that is, the included angle between the upper end of the LowE glass 2 and the upper end of the cadmium telluride thin-film photovoltaic glass 3 is 10 - 15°.

[0018] A cavity structure 4 is formed between the LowE glass 2 arranged obliquely and the cadmium telluride thin-film photovoltaic glass 3 arranged vertically. A corrugated air inlet 5 is provided at the top of the cavity structure 4, and a diffused air outlet 6 is provided at the bottom. Air flows in at high speed from the narrow air inlet at the top, decelerates and increases pressure in the diffusion section in the middle of the cavity structure 4, and finally flows out from the wide outlet at the bottom, realizing enhanced ventilation by the Venturi effect.

[0019] The multimodal sensing array 7 is located in the cavity structure 4. The multimodal sensing array 7 includes a VOCs sensor 8 and a particle counter 9; it is mainly used to detect the air quality near the curtain wall system. According to requirements, common sensors such as temperature and humidity sensors can also be set.

[0020] The bionic ventilation mechanism 10 includes louvers 11 made of shape memory alloy and a shaftless scroll fan 12. In this design, the louvers 11 are arranged on both sides of the cavity structure 4, that is, on the mounting plates connecting both sides of the LowE glass 2 and the cadmium telluride thin-film photovoltaic glass 3. It is also possible to directly replace the mounting plates on both sides of the LowE glass 2 and the cadmium telluride thin-film photovoltaic glass 3 with the louvers 11, and directly fix one side of the louvers 11 to the wall. The shaftless scroll fan 12 is fixed on the surface of the cadmium telluride thin-film photovoltaic glass 3 and is electrically connected to the cadmium telluride thin-film photovoltaic glass 3.

[0021] The curvature of the blades of the louvers 11 automatically adjusts with temperature change, and cooperates with the shaftless scroll fan 12 driven by piezoelectric ceramics to enhance the air flow around the curtain wall and inside the cavity structure 4, and the noise < 35 dB.

[0022] This design also has an energy system. The cadmium telluride thin-film photovoltaic glass 3 can convert solar energy into direct current, and the conversion efficiency reaches 19%. The converted electric energy can be stored in the lithium iron phosphate battery in the wall to achieve self-supply of energy.

[0023] A wireless energy transmission unit is provided at the connection between the gradient light-transmitting composite curtain walls 1. The wireless energy transmission unit includes several coils, and electric energy is transmitted between adjacent curtain walls through magnetic resonance coupling between the coils.

[0024] Microchannel heat recovery pipelines are printed on the back of the cadmium telluride thin-film photovoltaic glass 3 to cool the cadmium telluride thin-film photovoltaic glass 3 and collect waste heat; a docosane / expanded graphite composite phase change material is filled in the cavity structure 4. The phase change point of the docosane / expanded graphite composite phase change material is 24 °C, and the latent heat value ≥ 180 kJ / kg. It buffers temperature fluctuations through solid-liquid phase change, realizes heat storage during the day and heat release at night, and suppresses the indoor temperature amplitude to ±1.2 °C.

[0025] The vertical green plant module 13 includes green plants, a cultivation rack 14, an aeroponic cultivation unit, and a spectrum synergy system. The cultivation rack 14 includes two or more guide rails 16 vertically arranged on the wall surface and several alloy brackets 15. The guide rails 16 can adopt dovetail guide rails 16 to enhance the stability between the alloy brackets 15 and the guide rails 16. The alloy bracket 15 itself is composed of two sections of brackets connected by sliding, that is, the alloy bracket 15 itself can be telescopic. Through fasteners such as screws, the alloy bracket 15 can be fixed at different heights of the guide rail 16 and the length of the alloy bracket 15 itself can be fixed.

[0026] In this design, the vertical green plant modules 13 on the front side of the same gradient light-transmitting composite curtain wall 1 are arranged in a gradient, that is, the length of the alloy bracket 15 located higher is shorter. A planting groove 19 is provided on the side of the alloy bracket 15 away from the wall, and the green plants are planted in the planting groove 19.

[0027] The aeroponic cultivation unit in this design is an ultrasonic atomization sheet 17. In this design, the ultrasonic atomization sheet 17 is used to break up the nutrient solution to generate a naturally floating mist, and then a small fan blows the mist from the bottom to the outlet to humidify the air and generate a rich amount of negative oxygen ions to achieve the irrigation of the green plants.

[0028] The aeroponic cultivation unit also has a root sensing array and a targeted supply device. The root sensing array monitors the root biomass density through a capacitive sensor and combines a convolutional neural network to identify nutrient deficiency symptoms; the targeted supply device releases Fe-EDTA and KH2PO4 nutrient ions as needed through a microfluidic chip.

[0029] The spectrum synergy system includes a plant growth lamp 18 integrating red light LEDs and blue light LEDs. The red light LEDs and the blue light LEDs are dynamically adjusted according to a light intensity ratio of 1:1 - 2.3 to increase the photosynthetic rate.

[0030] The specific embodiments described above further elaborate on the technical problems solved, technical solutions, and beneficial effects of the present invention. It should be understood that the above are only specific embodiments of the present invention and are not used to limit the present invention.
