[0002] Photovoltaic curtain wall is a green, environmentally friendly and renewable energy utilization method that integrates solar energy into architectural design. It combines architectural aesthetics, building thermal engineering, curtain wall, energy and electricity, which can not only improve the energy efficiency of buildings, but also improve the appearance and comfort of buildings. On the one hand, the adjustable photovoltaic curtain wall converts solar energy into electrical energy, directly supplies it to buildings or provides guarantee for subsequent use through power storage devices; at the same time, by adjusting ventilation and heat dissipation, sunshade and heat insulation, and lighting, it can reduce the heat gain and adverse effects of the glass curtain wall, reduce the operating temperature of the battery, and increase the battery power generation. At the same time, it can also adjust the sunlight entering the room, reduce lighting energy consumption, and reduce the temperature inside the building to improve the indoor environment.

[0003] Photovoltaic curtain wall technology is currently widely used in commercial, residential, public building and other fields. It usually has to have good light transmittance in its application so as not to affect lighting while generating electricity from light. However, in the hot season, the light-transmitting components will cause the solar panels to be exposed to high temperatures, which will result in low photoelectric conversion efficiency and short battery life. The present invention utilizes adjustable opening and closing degrees, liftable shutter devices and ventilation holes that can form circulating airflow to achieve ventilation, heat dissipation and sunshade effects, thereby improving the conversion efficiency and service life of photovoltaic cells. It is a feasible solution to solve the problems of high energy consumption and poor optical effects of existing glass curtain walls. It also provides an innovative solution to the problems of heat dissipation, ventilation and heat gain of photovoltaic curtain walls. Summary of the invention

[0004] The present invention overcomes the deficiencies in the prior art and provides a breathing type dynamically adjustable solar photovoltaic and thermal integrated curtain wall.

[0005] The purpose of the present invention is achieved through the following technical solutions.

[0006] A breathing type dynamically adjustable solar photovoltaic and thermal integrated curtain wall comprises: a glass cover plate and a glass bottom plate are respectively arranged on the inner sides of the front and rear end surfaces of an installation frame, a photovoltaic module and a shutter device are respectively arranged on the inner sides of the glass cover plate and the glass bottom plate, the photovoltaic module and the shutter device form a ventilation cavity in the installation frame, the ventilation cavity is connected to a ventilation hole groove structure arranged on the installation frame, and a gas drive device is arranged on the installation frame in the ventilation cavity.

[0007] The photovoltaic module comprises a light-transmitting photovoltaic panel and a transparent back panel, wherein the light-transmitting photovoltaic panel is arranged between the glass cover panel and the transparent back panel.

[0008] The light-transmitting photovoltaic panel and the transparent back sheet are connected by transparent sol lamination.

[0009] A shutter slide and a shutter collection groove are provided in the shutter device. The shutter slides are symmetrically arranged on both sides of the shutter device frame. Guide rods are provided in both shutter slides, and shutters are provided on the guide rods. The shutter collection groove is arranged on the upper inner side of the shutter device, and the setting position and structural shape of the shutter collection groove match the shutter.

[0011] A battery pack is arranged in the installation frame, and the battery pack is respectively connected with corresponding circuits of the photovoltaic component, the shutter device and the gas drive device.

[0012] The installation frame is a rectangular hollow frame structure, the first air inlet slot hole and the second air inlet slot hole are respectively arranged on the side wall of the lower frame body of the installation frame facing the front end and the top wall facing the upper end, and the first air inlet slot hole and the second air inlet slot hole are connected to the internal cavity of the installation frame;

By integrating the built-in sunshade, breathing curtain wall and solar photovoltaic thermal integrated technology, two-level ventilation slots are opened on the upper and lower sides of the unit curtain wall installation frame. The first-level ventilation slot is used for external ventilation, that is, the wind enters from the lower front of the integrated curtain wall and dissipates from the upper front. The second-level ventilation slot is used for the upper and lower connection of the integrated curtain wall to form a larger cavity, which can be combined with indoor ventilation. When the temperature in the cavity is higher than the set value, the ventilation slot is opened. On the one hand, ventilation can be achieved through wind pressure and heat pressure. On the other hand, the controller can also start the vertical axial flow fan to enhance ventilation.

[0029] The photovoltaic assembly comprises a light-transmitting photovoltaic panel 2 and a transparent back panel 3 , wherein the light-transmitting photovoltaic panel 2 is arranged between the glass cover panel 1 and the transparent back panel 3 .

[0030] The light-transmitting photovoltaic panel 2 and the transparent back panel 3 are connected by lamination via a transparent sol 7 .

[0031] A shutter slide 51 and a shutter storage groove 54 are provided in the shutter device 5. The shutter slide 51 is symmetrically arranged on both sides of the interior of the shutter device 5 frame. Guide rods 53 are provided in both shutter slides 51. Shutters 52 are provided on the guide rods 53. The shutter storage groove 54 is arranged on the upper inner side of the shutter device 5. The setting position and structural shape of the shutter storage groove 54 match the shutters 52.

[0032] A controller 9 and a temperature sensing element 12 are disposed in the installation frame 8 . The temperature sensing element 12 is connected to the controller 9 by a circuit. The controller 9 is matched with the guide rod 53 .

[0033] A battery pack 11 is disposed in the installation frame 8 , and the battery pack 11 is respectively connected to corresponding circuits of the photovoltaic assembly, the shutter device 5 and the gas drive device 10 .

[0034] The mounting frame 8 is a rectangular hollow frame structure, the first air inlet slot 81 and the second air inlet slot 82 are respectively arranged on the side wall of the lower frame body of the mounting frame 8 facing the front end and the top wall facing the upper end, and the first air inlet slot 83 and the second air inlet slot 84 are connected to the internal cavity of the mounting frame 8;

[0035] The first air outlet slot hole 83 and the second air outlet slot hole 84 are respectively arranged on the side wall facing the front end and the top wall facing the upper end of the upper frame of the installation frame 8. The first air outlet slot hole 83 and the second air outlet slot hole 84 are connected to the first air inlet slot hole 81 and the second air inlet slot hole 82 through the hollow passage inside the installation frame 8.

[0036] The gas driving device 10 is arranged on the bottom frame of the mounting frame 8 .

[0037] The gas driving device 10 adopts a small vertical axial flow fan.

[0038] The working principle of the present invention is as follows: Figure 1-2As shown, the device forms an internal space of the installation frame 8 by arranging the glass cover plate 1 and the glass bottom plate 6 on the front and rear end surfaces of the installation frame 8, thereby achieving the effect of heat preservation and heat insulation. Photovoltaic components and shutter devices 5 are arranged in the internal space to realize the function of photoelectric conversion to provide energy for the shutter device and the gas drive device 10. The shutter device controls the shutter 52 through the controller 9 to achieve the shading effect. The gas drive device 10 is linked and controlled based on the temperature sensing element 12 in the installation frame 8, and the gas drive device 10 provides the power of air flow in the ventilation cavity 4, so that the air can circulate through the ventilation hole groove structure to achieve the heat dissipation function. Two-level ventilation slots are opened on both sides of the upper and lower frames of the installation frame 8. The first-level ventilation slot is used for external ventilation, that is, the wind enters from the lower front side of the integrated curtain wall and disperses from the upper front side; the second-level ventilation slot is used for the upper and lower connection of the integrated curtain wall to form a larger cavity. When the temperature in the cavity of the installation frame 8 is higher than the set value, the ventilation slots are opened to ventilate through wind pressure and heat pressure, or the controller 9 starts the gas drive device 10 to enhance ventilation. The circulating air flow in the ventilation cavity 4 takes away heat, reduces the battery operating temperature, and reduces the impact of the curtain wall on the interior. At the same time, according to the indoor lighting needs, the shading can be adjusted to achieve control of natural lighting. A photovoltaic direct-charging battery pack 11 is provided in the installation frame to power the drive device. This scheme adopts a breathing dynamically adjustable photovoltaic-thermal integrated curtain wall module design, which integrates built-in shading, breathing curtain wall and solar photovoltaic-thermal integrated technology.

[0039] Preferably, the glass cover 1 is made of low-iron ultra-white tempered glass, which has a light transmittance of more than 90% within the wavelength range of the solar spectrum and has good thermal stability and mechanical strength.

[0040] The glass bottom plate 6 is made of vacuum glass. As an energy-saving glass, hollow glass has a very significant thermal insulation effect. Because of its low heat transfer coefficient, vacuum glass can effectively reduce the electricity required for heating, so as to achieve the effect of increasing revenue and reducing expenditure.

[0041] The light-transmitting photovoltaic panel 2 adopts light-transmitting, high-efficiency, high-temperature-resistant thin-film batteries.

[0042] The mounting frame 8 is made of a lightweight, high-strength alloy, preferably aluminum alloy or titanium alloy.

[0043] Further, if Figure 3-4As shown, the shutter device 5 obtains the temperature of the light-transmitting photovoltaic panel 2 through the temperature sensing element 12 and transmits the signal to the controller 9 for receiving. The controller 9 drives the guide rod 53 to make it move vertically up and down in the shutter slide 51 to adjust, thereby controlling the opening and closing angle of the shutter 52 to dissipate heat or shade. The shutter storage slot 54 is used to store the shutter 52. The temperature sensing element 12 is arranged on the inner side of the installation frame 8, which is used to monitor the temperature change of the light-transmitting photovoltaic panel 2 at all times. When the temperature reaches the high temperature warning, the controller 9 intervenes to cool it down. The left and right sides of the installation frame 8 adopt a hidden line structure to fit the aesthetic design concept of the curtain wall building. When there is sufficient light, the light-transmitting photovoltaic panel 2 performs light-heat conversion and stores the excess electrical energy in the battery pack 11 for storage; when there is insufficient light in rainy and snowy weather, the battery pack 11 provides power for the controller 9 and the gas drive device 10.

[0044] Preferably, the blinds 52 are made of aluminum alloy or wood and bamboo paint, and have the characteristics of sunshade, heat insulation, non-aging, breathable and fireproof. The blinds 52 can be controlled manually or electrically, and can adjust the light at any angle, or can be completely retracted.

[0045] like Figure 5 As shown, the present solution utilizes a gas driving device 10 to drive the gas to flow. The gas driving device 10 uses a small vertical axial flow fan fixedly connected to the upper cavity area on the lower side of the mounting frame 8, that is, at the air inlet position, which can increase the air intake. The vertical axial flow fan can effectively utilize the wind energy around the building. Compared with the horizontal axial flow fan, the vertical axial flow fan has the advantages of higher efficiency and lower noise.

[0046] Furthermore, during use, the first air inlet slot 81, the second air inlet slot 82, the first air outlet slot 83 and the second air outlet slot 84 will cooperate with the air valve structure to control the opening and closing of each hole, so that different heat dissipation paths are formed inside to meet different environmental requirements. At the same time, ventilation and air-conditioning devices will be added according to environmental requirements to connect with the heat dissipation circuit.

[0047] like Figure 6 As shown, this solution uses sunlight to irradiate the surface of the light-transmitting photovoltaic panel 2 for photoelectric conversion. The sunlight can pass through the light-transmitting photovoltaic panel 2 into the room to ensure indoor lighting. It includes four working conditions, as follows:

[0048] 1. When the temperature of the light-transmitting photovoltaic panel 2 is relatively high, that is, 30℃<t≤40℃. Air enters the ventilation slot structure on the installation frame 8 of the curtain wall module to form a circulating airflow for self-cooling. Specifically, air enters the cavity from the first air inlet slot 81 and the second air inlet slot 82, and flows out from the first air outlet slot 83 and the second air outlet slot 84. The formed circulating airflow can achieve heat dissipation.

[0049] 2. Under continuous high temperature conditions, that is, when the temperature is greater than 40°C, the first solution alone cannot dissipate heat efficiently. At this time, the controller 9 starts the gas drive device 10 to increase the degree of air flow disturbance under the high-speed rotation of the impeller. The high-speed circulating airflow formed can quickly reduce the curtain wall temperature.

[0050] 3. In the high temperature section during the day in summer, the remote controller 9 can be used to open the shutters 52 for sunshade, and the opening and closing degree of the shutters 52 can be adjusted to adjust the indoor lighting.

[0051] 4. In spring and winter, the heat generated by the photoelectric conversion is collected in the ventilation cavity 4, acting as an insulation wall.

[0052] The controller 9 and the gas driving device 10 in the above working condition are powered by the battery pack.

[0053] The embodiments of the present invention are described in detail above, but the contents described are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
