Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic curtain walls, in particular to a ventilated photovoltaic curtain wall with thermal insulation function. Background Art

[0002] Against the backdrop of increasingly severe climate change and my country's vigorous promotion of the implementation of the dual-carbon strategy, photovoltaic curtain walls have been increasingly widely used. In the integrated design of building photovoltaics, rooftop photovoltaics have reached a considerable breadth of application. In addition, photovoltaic curtain walls located on the facades of buildings have also been increasingly widely used. Since photovoltaic panels will generate heat when working, generally when the temperature rises to above 45 degrees Celsius (taking crystalline silicon photovoltaic panels as an example), the photoelectric conversion efficiency begins to gradually decrease. Therefore, a major problem that photovoltaic curtain walls need to solve is heat dissipation to ensure appropriate power generation efficiency. In addition, in cold areas of my country (average temperature in January -10℃~0℃) or severe cold areas (average temperature in January ≤-10℃), when the outdoor temperature is below 0℃, not only the power generation efficiency of photovoltaics will be reduced, but also the durability of packaging materials and cell film layers will be reduced. In order to ensure the durability of materials and ensure photovoltaic power generation efficiency in winter, warming measures should be considered. At the same time, the heat energy generated by photovoltaic panels is dissipated and not effectively utilized. If it is utilized, it can effectively enhance the overall thermal performance of the exterior wall.

[0003] In order to solve the above problems, the existing technical solutions include increasing the spacing between the photovoltaic curtain wall and the backing plate, increasing the cavity air volume, and controlling the temperature rise of the photovoltaic curtain wall. According to the new version of the national standard "Building Area Calculation Rules", the building area is calculated according to the finished surface of the exterior wall, so this method will significantly reduce the building room rate and affect the economic efficiency of the building. There is also the increase in the opening of the photovoltaic curtain wall to increase the flow of cavity air and external air to control the temperature rise of the photovoltaic curtain wall. Architecture is a combination of technology and art. For the purpose of heat dissipation, excessively increasing the gap between photovoltaic panels is difficult to meet the architect's pursuit of architectural aesthetics. Another method is to increase the cavity air flow rate and control the temperature rise of the photovoltaic curtain wall by adding active heat dissipation measures such as fans. However, this measure consumes additional electricity and reduces the efficiency of photovoltaic power generation. In addition, the arrangement of electrical equipment in the external protective structure will increase the cost of building enclosures and reduce the weather resistance and durability of buildings.

The lower part of the curtain wall main keel 1 is fixedly connected, and the other end of the lower vertical wire trough 9 is fixedly connected to the lower horizontal wire trough 11. The upper electric control guide assembly 6 includes a guide member fixing frame 12, an upper driving device 13 and an arc guide plate 14. The guide member fixing frame 12 is detachably fixed to the curtain wall main keel 1 at the upper opening of the cavity through a channel steel, and the upper driving device 13 is fixed under the guide member fixing frame 12. The arc guide plate 14 is fixed in the guide member fixing frame 12, and the top of the arc guide plate 14 is connected to the upper driving device 13. The upper driving device 13 is meshed and connected, and the upper driving device 13 drives the bottom end of the arc guide plate 14 to contact the upper horizontal wire groove 10 and the curtain wall back plate 5 respectively. The lower electric control guide assembly 7 includes a lower driving device 19 and a guide louver 20. The lower driving device 19 is fixed in the lower vertical wire groove 9. The guide louver 20 is meshed and connected with both sides of the lower driving device 19, and is fixed in the lower vertical wire groove through the central axis of the guide louver 20. The lower driving device 19 drives the guide louver 20 to block and open the lower opening of the cavity.

[0039] The utility model arranges the upper and lower electrically controlled flow guide components at the upper opening of the cavity and the lower opening of the cavity, respectively. The upper electrically controlled flow guide component 6 arranged at the upper opening of the cavity uses the upper driving device 13 to drive the other end of the arc-shaped flow guide plate 14 to contact the upper horizontal line groove 10 and the curtain wall back plate, respectively. When the upper driving device 13 drives the other end of the arc-shaped flow guide plate 14 to contact the upper horizontal line groove 10, the arc-shaped flow guide plate 14 blocks the upper opening of the cavity, which can preserve the heat dissipated by the photovoltaic panel power generation, enhance the thermal performance of the building, and reduce the energy consumption of the building. When the upper driving device 13 drives the other end of the arc-shaped flow guide plate 14 to contact the curtain wall back plate 5, the arc-shaped flow guide plate 14 opens the upper opening of the cavity, and the arc-shaped structure of the arc-shaped flow guide plate 14 guides the hot air to flow out of the cavity, reducing the temperature in the cavity, that is, reducing the temperature of the photovoltaic panel and improving the power generation efficiency. The lower electric control flow guide assembly 7 arranged at the lower opening of the cavity uses the lower driving device 19 to drive the flow guide louver 20 to open and close the lower opening of the cavity. When the flow guide louver 20 opens the lower opening of the cavity, it is conducive to the external cold air to enter the cavity, reduce the temperature in the cavity, thereby reducing the temperature of the photovoltaic panel for power generation and improving the power generation efficiency of the photovoltaic panel. In a low temperature environment, when heat preservation is required, the lower driving device 19 can be controlled to drive the flow guide louver 20 to block the lower opening of the cavity, so as to prevent the external cold air from entering the cavity, and at the same time, to save the heat emitted by the photovoltaic panel from flowing out, maintain the cavity temperature, compensate for the heat lost under low temperature conditions, maintain the temperature of the photovoltaic panel, improve the power generation efficiency, and increase the temperature of the building under low temperature conditions to reduce energy consumption. The rectangular square tubes in the upper and lower horizontal wire grooves respectively arranged at the top and bottom ends of the photovoltaic panel frame 3 are rectangular square tubes with open sides, and the opened rectangular square tubes can facilitate the maintenance and replacement of the wires. The upper electric control flow guide assembly 6 includes a flow guide fixing frame 12, an upper driving device 13 and an arc-shaped flow guide plate 14. The upper driving device 13 is fixed under the flow guide fixing frame 12. The arc-shaped flow guide plate 14 is stuck in the flow guide fixing frame 12. The top of the arc-shaped flow guide 14 is meshed and connected with the upper driving device 13 to form an integral upper electric control flow guide assembly 6. The upper electric control flow guide assembly 6 is detachably fixed to the main keel 1 of the curtain wall with an upper opening in the cavity through the flow guide fixing frame 12 and the channel steel. The upper electric control flow guide assembly 6 can be removed from the main keel of the curtain wall as a whole.

[0040] In a high temperature environment, under the same working conditions (ambient temperature 20, 30, 35, 40°C, ambient wind speed 3m / s, wind direction perpendicular to the curtain wall surface), the upper drive device 13 drives one end of the arc guide plate 14 to contact the curtain wall back plate to open the upper opening of the cavity, and the lower drive device 19 drives the guide louver 20 to open the lower opening of the cavity. The average temperature of the photovoltaic panel in the utility model can be reduced by about 0.4°C compared with the photovoltaic curtain wall in conventional technology, and the maximum temperature difference of the photovoltaic panel is about 1.38°C. In a low temperature environment, when heat preservation is required, under the same working conditions (outdoor temperature 0, -5, -10, -15°C), the upper drive device 13 drives one end of the arc guide plate 14 to contact the upper horizontal line groove 10 to block the upper opening of the cavity, and the lower drive device 19 drives the guide louver 20 to block the lower opening of the cavity. The average temperature of the photovoltaic panel in the utility model can be increased by about 7-11°C compared with the conventional photovoltaic curtain wall model.
