Description

Technical Field

[0001] This utility model relates to the field of building curtain wall technology, and in particular to a double-layer ventilated photovoltaic curtain wall. Background Technology

[0002] A curtain wall is the exterior cladding of a building; it is a lightweight wall structure with decorative features and does not bear the load of the main structure. Modern curtain walls can utilize the space provided by the building facade to install solar photovoltaic panels, forming a photovoltaic curtain wall that converts solar energy into electricity, thus alleviating the pressure on the power grid.

[0003] The existing curtain wall is made of transparent or semi-transparent glass, and the indoor temperature is easily affected by the external environment. For example, under the intense radiation of the sun in summer, the air temperature near the curtain wall is much higher than the indoor air temperature, which intensifies the heat exchange between the indoor and outdoor areas, resulting in high air conditioning energy consumption in summer. In winter, the indoor temperature is higher than the outdoor temperature, resulting in high heating energy consumption in winter. Even if double curtain walls are installed to increase isolation, it is still impossible to completely eliminate the heat exchange between the indoor and outdoor air. Utility Model Content

[0010] As an alternative, a powered turbofan that supplies air upwards is installed in the hollow ventilation layer.

[0011] As an optional solution, a flip-up window is provided at the first, second, third, and fourth switchable vents. The flip-up windows of the first and second switchable vents are rotatably connected to the inner curtain wall and open toward the outer curtain wall, respectively. The flip-up windows of the third and fourth switchable vents are rotatably connected to the outer curtain wall and open outward.

[0012] As an alternative, each flip window is controlled by a separate motor to open or close.

[0013] As an alternative, the outer curtain wall is equipped with baffles that limit the opening angle of the flip-up windows of the first and second operable ventilation openings, respectively.

[0014] As an optional solution, embedded parts are installed on the exterior facade, the inner curtain wall is fixed to the embedded parts, and an insulation layer is installed between the inner curtain wall and the exterior facade.

[0016] As an alternative, solar photovoltaic panels are installed on the outer curtain wall.

[0017] The beneficial effects of this utility model are:

[0018] This double-layer ventilated photovoltaic curtain wall can intelligently regulate indoor and outdoor air circulation by controlling the opening and closing of corresponding ventilation openings on the inner and outer curtain walls, maintaining stable indoor temperature, reducing the impact of heat exchange caused by temperature differences, significantly reducing air conditioning energy consumption in summer and heating energy consumption in winter, and improving indoor environmental comfort.

[0029] Furthermore, the terms "first" and "second" are merely used to distinguish between different terms in description and do not have any special meaning.

[0030] Please see Figure 1 As shown, this embodiment provides a double-layer ventilated photovoltaic curtain wall, including an inner curtain wall 1 and an outer curtain wall 2 installed on the exterior facade of each floor of a building. The outer curtain wall 2 is located outside the inner curtain wall 1, and a hollow ventilation layer 3 is formed between the inner curtain wall 1 and the outer curtain wall 2. The hollow ventilation layers 3 on each floor are separated. The bottom of the inner curtain wall 1 is provided with a first operable ventilation opening 4, the top of the inner curtain wall 1 is provided with a second operable ventilation opening 5, the bottom of the outer curtain wall 2 is provided with a third operable ventilation opening 6, and the top of the outer curtain wall 2 is provided with a fourth operable ventilation opening 7.

[0031] See details Figure 2 In the external ventilation state, the first switchable vent 4 and the fourth switchable vent 7 are open, while the second switchable vent 5 and the third switchable vent 6 are closed, forming an airflow channel in the hollow ventilation layer 3 through which air enters from the first switchable vent 4 and exits through the fourth switchable vent 7. Thus, indoor air is exhausted to the outside through the hollow ventilation layer 3, ensuring air circulation, achieving rapid indoor ventilation, and improving indoor comfort.

[0032] See details Figure 3 In summer, the third and fourth switchable vents 6 and 7 are open, while the first and second switchable vents 4 and 5 are closed. This creates an airflow channel within the hollow ventilation layer 3, with air entering through the third vent 6 and exiting through the fourth vent 7. This airflow continuously carries away heat from the hollow ventilation layer 3, reducing its impact on indoor air heat exchange and achieving a certain degree of insulation, thus lowering air conditioning energy consumption in summer.

[0033] See details Figure 4In winter operation, the first and second switchable vents 4 and 5 are open, while the third and fourth switchable vents 6 and 7 are closed. This creates an airflow channel within the hollow ventilation layer 3, with air entering through the first vent 4 and exiting through the second vent 5. This draws cold air from the bottom of the room into the hollow ventilation layer 3, where it warms under solar radiation and rises before flowing back into the room, achieving internal air circulation and providing a degree of heating while reducing winter heating energy consumption.

[0034] Optionally, the hollow ventilation layer 3 is equipped with an upward-flowing powered turbofan 8, which helps airflow. Given the principle that hot air rises and cold air sinks, upward airflow is more suitable.

[0035] Optionally, a flip-up window 9 is provided at the first switchable vent 4, the second switchable vent 5, the third switchable vent 6, and the fourth switchable vent 7. The flip-up window 9 of the first switchable vent 4 and the second switchable vent 5 are rotatably connected to the inner curtain wall 1 and open toward the outer curtain wall 2, respectively. The flip-up window 9 of the third switchable vent 6 and the fourth switchable vent 7 are rotatably connected to the outer curtain wall 2 and open outward.

[0036] Furthermore, each flip window 9 is controlled by a separate motor to open or close, meeting ventilation requirements under different conditions.

[0037] Furthermore, the outer curtain wall 2 is provided with baffles 10 that limit the opening angle of the flip-up window 9 of the first operable ventilation opening 4 and the flip-up window 9 of the second operable ventilation opening 5, respectively, to ensure that the flip-up window 9 operates within the normal range.

[0038] Optionally, an embedded part 11 is provided on the exterior facade, the inner curtain wall 1 is fixed to the embedded part 11, and an insulation layer 12 is provided between the inner curtain wall 1 and the exterior facade to improve the thermal insulation between the hollow ventilation layer 3 and the exterior facade.

[0039] Optionally, a connecting steel plate 13 is provided between the inner curtain wall 1 and the outer curtain wall 2. The connecting steel plate 13 is located at the top and bottom of the hollow ventilation layer 3. Fireproof rock wool 14 is provided between the connecting steel plate 13 at the bottom of the upper hollow ventilation layer 3 and the connecting steel plate 13 at the top of the lower hollow ventilation layer 3 to improve the independence of each hollow ventilation layer 3.

[0040] Optionally, solar photovoltaic panels 15 are installed on the outer curtain wall 2.

[0041] In summary, this double-layer ventilated photovoltaic curtain wall has the following advantages:

[0042] ① Improve energy efficiency by intelligently regulating indoor and outdoor air circulation, which can significantly reduce air conditioning energy consumption in summer and heating energy consumption in winter;

[0043] ② Improve indoor comfort by automatically adjusting ventilation according to the temperature difference between indoors and outdoors, thereby enhancing human comfort;

[0044] ③ It has good environmental adaptability and can intelligently coordinate with climate change to adapt to the climate characteristics of different regions and times.

[0045] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
