Description

Technical Field

[0001] The utility model relates to the field of building energy conservation, and more specifically to a building wind-solar fusion system. Background Art

[0002] With the steady advancement of the "dual carbon" policy and the promotion of the concept of resilient cities, traditional passive energy-saving buildings alone are no longer able to adapt to the development trend of near-zero carbon buildings. Moreover, at present, most buildings do not fully consider the active energy design of buildings during the design and operation stages, and the light energy and wind energy on the exterior surfaces of large areas of buildings are not fully utilized and effectively combined. The existing equipment has a large initial investment, and the effect of the later operation and maintenance stage is not ideal, resulting in a waste of resources and energy. For example:

[0003] (1) The current form of building wind farm power generation is mainly vertical axis wind turbines, which are usually scattered on the roof or roof of the building. Such vertical axis wind turbines often have high requirements for wind speed. The power generation is not stable enough under light wind conditions, resulting in unsatisfactory results. In the early stage, multiple wind turbines need to be invested to maximize the use of wind energy on the roof of the building, resulting in large initial investment. From an aesthetic point of view, in order to ensure its power generation efficiency, such wind turbines are usually higher than the roof by a certain distance, resulting in visual clutter.

[0004] (2) There are two main ways to place photovoltaic panels on building roofs. One is to lay them flat on the roof, and the other is to place them on the roof by forming a certain angle between the frame and the roof. Although both methods can effectively utilize light energy, due to their direct connection with the roof, when inspecting the roof's waterproofing, etc., the photovoltaic panels need to be removed on a large scale. In addition, there are too many points of connection with the roof during the installation process. The existence of too many connection points on the roof greatly increases the risk of roof leakage, which poses a great hidden danger to the later operation and maintenance of the building.

[0005] Therefore, the art still lacks a new type of active energy-saving building that can effectively overcome the above problems. Utility Model Content

[0078] After extensive and in-depth research and a large amount of screening, the inventor has developed a building wind-solar fusion system for the first time. The building wind-solar fusion system collects wind energy from all directions of the building, generates electricity through wind turbines, and effectively utilizes wind energy of new or existing buildings; photovoltaic panels are integrated with wind collection channels and installed overhead on the roof of the building, which does not affect the normal function of the building roof, and effectively avoids the maintenance, leakage and other problems caused by direct installation on the roof, and can also cool the working photovoltaic panels through the wind collection channel; water resources are recovered through the water collection trough, and the recovered water resources can be used for daily cleaning operations of photovoltaic panels, etc.; other equipment is cooled or kept warm through heat exchange equipment to achieve heat recovery and utilization; on this basis, the utility model was completed.

[0079] With the steady advancement of the "dual carbon" policy and the promotion of the concept of resilient cities, traditional passive energy-saving buildings alone are no longer able to adapt to the development trend of near-zero-carbon buildings. New active energy-saving buildings not only have the advantages of passive energy-saving buildings, but can also create certain energy value. Energy is organically integrated into all fields, industries, and links of the entire life cycle of buildings, gradually transforming from traditional passive buildings to active buildings, highlighting the natural advantages of the integration of buildings and energy, and embodying the ideological theory of building-energy integration.

[0080] The utility model of the building wind-solar fusion system can make full use of the wind energy in nature, and efficiently convert the wind energy into electrical energy without affecting the basic use functions of the building, and store it. It can be used for the building itself and can also feed back to other power facilities. The building wind-solar fusion system provides an effective and sustainable technical solution for active buildings. As it is used by more and more buildings in the future, it can provide strong support for achieving the "dual carbon" goals on schedule and provide an effective path for the implementation of the concept of resilient cities, with important environmental and social benefits.

[0081] On the one hand, the utility model uses devices installed on the roof and the facade to efficiently collect the wind pressure formed by the building at the roof eaves and the wind pressure formed by the building facade to one place, and sets a wind turbine generator at the collection point to generate electricity. Only a single power generation device is used to efficiently complete the power generation process, reducing the investment in early power generation equipment and later operation and maintenance costs. In addition, the device is not limited to being installed on the roof of the building, but can also be installed at the bottom floor, middle floor and other locations of the building; on the other hand, the photovoltaic power generation panel is installed on the device to reduce the direct relationship between the installation of the photovoltaic power generation panel and the roof. At the same time, the wind tunnel effect formed by the device can play a certain role in cooling the photovoltaic power generation panel during operation, and can also be combined with other functions with heat exchange requirements;

[0082] This utility model innovatively solves the later operation and maintenance problems caused by the inefficient utilization of building wind farms and the direct placement of photovoltaic panels on the roof. The system uses non-combustible materials and has no effect on the fire resistance of the building itself. It also maximizes the utilization of the building roof while ensuring the basic functions of the building, fully reflecting the natural advantages of the integration of building and energy. In particular, the retrofitting and renovation of existing buildings is of great significance to improving the initiative of existing buildings. It is also a necessary link in realizing a resilient city. It not only has economic benefits, but also has significant social value.

[0083] The main advantages of the utility model include:

[0084] (1) The wind energy from all directions of the building is concentrated together to drive a small number of wind turbines to generate electricity, thereby improving the efficiency of a single generator and reducing the cost of initial equipment investment and subsequent operation and maintenance.

[0085] (2) By integrating the photovoltaic panels with the wind collection channel and installing them overhead on the roof of the building, it does not affect the normal function of the building roof, and effectively avoids the problems of maintenance and leakage caused by direct installation on the roof. The wind collection channel can also be used to cool the photovoltaic panels in operation.

[0086] (3) The water resources collected by large-scale, continuous photovoltaic panels are recycled and reused for daily cleaning operations of photovoltaic panels, which reduces the consumption of water resources and further highlights the advantages of negative energy consumption buildings.

[0087] (4) The system is applicable to both new and existing buildings, and does not occupy the functional space of the original building. It innovatively solves the problem of space limitation in the integration of new energy and architecture, making space utilization more intensive.

[0088] (5) By integrating equipment and pipelines with heat exchange requirements, a passive heat exchange solution is provided, which reduces the energy consumption of the equipment, improves the efficiency of the equipment, and reduces carbon emissions.

[0089] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, the accompanying drawings are schematic diagrams, so the device and equipment of the present invention are not limited by the size or proportion of the schematic diagrams.

[0090] It should be noted that in the claims and description of this patent, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "including one" do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0092] The building wind and solar fusion system of this embodiment is as follows Figure 1-12 As shown, it includes a vertical air collecting duct (1), a horizontal air collecting duct (2), a vertical axis wind turbine (3), a photovoltaic panel (4), a water collecting trough (5) and a heat exchange coil (6). The building has an exterior wall (7), a building corner (8), and an installation plane (9). The vertical air collecting duct (1) includes a vertical air collecting duct air inlet (101), a vertical air collecting duct air outlet (105) and a vertical air collecting duct cavity (103) located therebetween; the horizontal air collecting duct (2) includes a horizontal air collecting duct air inlet (201), a horizontal air collecting duct air outlet (204) and a horizontal air collecting duct cavity (202) located therebetween.

[0093] The vertical air collecting duct (1) is installed on the building facade outside the building corner (8), and the top is connected to the horizontal air collecting duct (2); the horizontal air collecting duct (2) is installed on the installation plane (9) and is adjacent to the building outer wall (7); the vertical axis wind turbine (3) is installed on the installation plane (9) and is located at a plurality of horizontal air collecting duct outlets (204); the photovoltaic power generation panel (4) is installed above the horizontal air collecting duct (2); the water collecting trough (5) is installed below the photovoltaic power generation panel (4) and is located above the horizontal air collecting duct (2); and the heat exchange coil (6) is installed on the inside or outside of the horizontal air collecting duct (2).

[0094] The vertical wind collecting duct (1) is a wind collecting device installed on the outside of the building corner (8) and in an inverted "L" shape. There are a number of vertical wind collecting duct air inlets (101) on both sides of the facade, which collect the wind diverted to the horizontal sides of the building's windward side. There is a fan-shaped guide plate (102) on the inside of the air inlet, which can introduce the wind into the vertical wind collecting duct cavity (103) and guide the wind to flow upward with the help of the "chimney" effect. A vertical partition (104) is provided in the middle position of the vertical wind collecting duct cavity (103) in the diagonal direction to avoid the formation of through wind. The cross-section at the top position of the vertical wind collecting duct (1) is in a curved shape and is connected to the horizontal wind collecting duct cavity (202) in the horizontal direction. The vertical wind collecting duct outlet (105) extends into the horizontal wind collecting duct cavity (202) for a certain distance. The size of the vertical wind collecting duct (1) can be determined according to factors such as the perennial prevailing wind direction, annual average wind speed, and model of the vertical axis wind turbine (3) at the location of the building.

[0095] The horizontal air collecting duct (2) is in the shape of a trumpet as a whole, and its outer wall can be a straight surface or a curved surface. It is mounted on the installation plane (9) through a frame and connected to the building outer wall (7). The horizontal air collecting duct air inlet (201) and the horizontal air collecting duct air outlet (204) are respectively located at the two ends of the horizontal air collecting duct cavity (202). The horizontal air collecting duct air inlet (201) is large and low in position, and the horizontal air collecting duct air outlet (204) is small and high in position. There is a narrower throat (203) on the inner side close to the horizontal air collecting duct air outlet (204). The above measures enable the wind flow to be accelerated exponentially when passing through the horizontal air collecting duct cavity (202). Through the setting of the narrow throat (203), a "Laval nozzle" effect is formed, so that the wind speed at the horizontal air collecting duct outlet (204) reaches a peak value. A plurality of horizontal air collecting ducts (2) are arranged along the outer wall (7) of the building, and the horizontal air collecting duct outlets (204) of the plurality of horizontal air collecting ducts (2) are gathered at a center to ensure that wind from different directions can reach the center position and ensure that the vertical axis wind turbine (3) is driven to rotate in a preset direction. The size of each component of the horizontal air collecting duct (2) can be determined based on factors such as the prevailing wind direction, annual average wind speed, wind field calculation, and the model of the vertical axis wind turbine (3) at the location of the building. The horizontal air collecting duct outlet (204) is divided into two forms according to the blade shape of the vertical axis wind turbine (3), one is the horizontal air collecting duct outlet vertically exhausting air (204-1), and the other is the horizontal air collecting duct outlet horizontally exhausting air (204-2).

The electric energy generated by the vertical axis wind turbine (3) can be directly used by the building itself, or can be stored or connected to the grid. The blade shape of the vertical axis wind turbine (3) is a new blade form that can take in air from the side and exhaust air from the top, and the power generation efficiency is improved by setting multiple blades.

[0097] The photovoltaic power generation panel (4) is installed above the horizontal air collecting duct (2), and the air flow in the horizontal air collecting duct cavity (202) can be used to take away the heat generated by the photovoltaic power generation panel (4) when it is working; the angle of the photovoltaic power generation panel (4) is lowered from the center of the building to the outside and slightly tilted, which is convenient for collecting precipitation and sewage generated by later maintenance without affecting the power generation efficiency of the photovoltaic power generation panel (4); the electricity generated by the photovoltaic power generation panel (4) can be directly used by the building itself, and can also be stored or connected to the grid. The photovoltaic power generation panel (4) is a crystalline silicon solar panel or a cadmium telluride power generation glass. The photovoltaic power generation panel (4) covers the entire installation plane (9), further improving the overall negative energy consumption of the building.

[0098] The water collecting tank (5) is installed below the photovoltaic power generation panel (4) to collect precipitation and sewage generated by the maintenance of the photovoltaic power generation panel (4). The water collecting tank (5) uses a siphon drain pipe that can generate electricity, and can generate electricity while draining water. The water collected by the water collecting tank (5) is connected to a water storage tank to provide a water source for the maintenance of the photovoltaic power generation panel (4), further reducing energy consumption.

[0099] The heat exchange coil (6) is installed above the outer side of the horizontal air collecting duct (2), and utilizes the temperature difference generated by the air flow in the horizontal air collecting duct cavity (202) to form heat exchange with the heat exchange coil (6), thereby achieving the purpose of cooling and heat dissipation. The heat exchange coil (6) is installed on the outer side and other inner walls of the horizontal air collecting duct (201), providing heat exchange space for the heat exchange coil (6) more efficiently.

[0100] The building corner (8) refers to the corner of the building, which is the part where the wind field of the building turns horizontally on the facade.

[0101] The installation plane (9) refers to the roof of the building. It further includes the ground floor of the building and the ground of other floors. It further includes the refuge floor, equipment floor, transfer floor, etc. set up in super high-rise buildings.
