DETAILED DESCRIPTION

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] In one embodiment of the present invention, the exterior facade of a building structure in an old residential area is renovated, and the three-dimensional model of the exterior facade of the building structure before the renovation is as follows: Figure 1 As shown, the thermal insulation decoration photovoltaic integrated system of the present invention is built on the facade of the building structure, such as Fig.10 As shown, the method comprises the following steps:

[0047] S1. Build the facade support system:

[0048] S1.1. Remove the damaged facades of old residential areas. According to the size of the door and window openings in the building structure of the old residential area, measure the building walls, draw horizontal and vertical lines, and level the facades of the building structures;

[0049] S1.2. According to the original building structure system, build the facade support structure components, including the vertical main keel support structure and the horizontal secondary keel support structure;

[0050] S2. Build a photovoltaic smart system for the facade:

[0051] S2.1. Install cable troughs and photovoltaic collection card slots in the horizontal secondary keel support structure, connect sensors and photovoltaic equipment, and access the smart operation system;

[0052] S2.2. Install vertical capillary water cooling channels in the vertical main keel support structure to control the physical temperature of the facade;

[0053] S3. Install thermal insulation decorative components and thermal insulation photovoltaic component units;

[0054] S3.1. According to the usage intentions of residents in old residential areas and the requirements for the exterior facade style of residential building structures, the heat transfer coefficient of the exterior wall is calculated based on the orientation of each side of the residence, and insulation materials are selected according to energy-saving requirements, and the number and installation locations of insulation decorative components and insulation photovoltaic components are configured;

[0055] S3.2. Dry-hang the thermal insulation decorative components and thermal insulation photovoltaic components on the facade supporting structure components, and disassemble, assemble, replace and adjust them according to changes in residents' needs.

[0056] It is particularly important to explain that the thermal insulation photovoltaic components and thermal insulation decorative components involved in the present invention are unit-type, connected to the main structure system of the curtain wall through angle steel and hangers, and the connection method adopts a small unit dry hanging method, also known as the aluminum alloy short slot dry hanging method, which is a type of steel hook dry hanging method. This construction method is connected to the frame through stone hangers, and adjacent panels are relatively "independent", with their own displacement space, and there is no load transfer between adjacent panels, which is convenient for free disassembly, combination and replacement of panels.

[0057] This embodiment builds a unitized dry-hanging thermal insulation and decoration photovoltaic integrated system for the renovation of the old community according to the above steps. According to the different needs of residents, the acceptance of different photovoltaic integrated facades and different energy-saving requirements, a thermal insulation and decoration photovoltaic integrated facade is formed through a combination method, such as Figure 2 As shown; through the combination method 2, the thermal insulation decorative photovoltaic integrated facade 2 is formed, as shown Figure 3 As shown, other possible facade combinations can also be installed.

[0058] In this embodiment, the unitized dry-hanging thermal insulation and decorative photovoltaic system includes: a supporting structure component, a thermal insulation and decorative component, and a thermal insulation photovoltaic component.

[0059] Specifically, the facade support structure components, such as Figure 4 As shown, it is divided into a vertical main keel support structure 1 and a horizontal secondary keel support structure 2. The vertical main keel support structure 1 is as shown in FIG. Figure 5 As shown, the transverse secondary keel support structure 2 is as shown in Figure 6 shown.

[0060] When constructing the facade support structure components, the steel frame system is installed first, so that it is installed outside the main building structure. While the facade is leveled, a complete curtain wall main structure system is formed.

[0061] Cable troughs and photovoltaic collection card slots are installed in the horizontal components of the supporting structure system, wherein the busbar is fixed in the cable trough and the photovoltaic equipment is installed in the photovoltaic collection card slot.

[0062] Multiple wiring cards are arranged in the middle of the horizontal component of the transverse secondary purlin support structure, connecting several sensors to collect information such as temperature and solar radiation intensity, which is finally fed into the building intelligent operation and management system.

[0063] Preferably, the sensors include: a temperature sensor installed on each thermal insulation photovoltaic component and thermal insulation decorative component, for collecting temperature data; a pyranometer installed on the upper surface of the building structure, for collecting solar radiation intensity data; a ranging sensor installed on the surface of the facade, for collecting the apparent flatness information of each component of the facade, and feeding back a displacement signal when the component is displaced beyond a preset amplitude.

[0064] The photovoltaic collection card slot is inserted into the combiner box, and the power is combined by the combiner box and converted into AC power through the inverter for use in buildings or connected to the power grid.

[0065] A capillary water cooling passage is reserved in the vertical structure of the vertical main keel support structure. The vertical pipes supporting the capillary water cooling passages are connected to the variable frequency water pump and water tank at the bottom as the water inlet, and the top is connected to the cold water recovery tank as the water outlet. The capillary water cooling passage cools the photovoltaic panel through the capillary passage of the thermal insulation photovoltaic module, together forming a temperature control system, which is incorporated into the building intelligent operation management system.

[0066] In this embodiment, Figure 7 As shown, the exterior facade of the old residential area is a lightweight brick wall 4, which is provided with embedded parts after structural reinforcement. The galvanized steel plate 5 is fixed to the embedded parts by expansion bolts 6, and an aluminum alloy backing plate 9 is sandwiched between the galvanized steel plate 5 and the lightweight brick wall to strengthen the integrity of the exterior facade of the old residential area.

[0067] Furthermore, in the vertical main keel support structure, vertical galvanized channel steel 8 is used as the vertical component, and in the horizontal secondary keel support structure, horizontal galvanized channel steel 10 is used as the horizontal component.

[0068] When installing the vertical structural support system, first install the vertical galvanized channel steel 8, install the vertical capillary water cooling passage 3 inside, and install the horizontal galvanized channel steel 10 horizontally to strengthen the support performance. Then, install the galvanized angle steel 7 horizontally, install the double-groove stainless steel hanger 12 through the stainless steel bolt 11, and install the photoelectric passage 13 inside the horizontal galvanized angle steel 7. The decorative thermal insulation integrated panel and the photovoltaic thermal insulation integrated panel are installed with aluminum frames, and are dry-hung on the facade through the galvanized angle steel 7 and the double-groove stainless steel hanger 12.

[0069] Specifically, thermal insulation decorative components, such as Figure 8 As shown, the outer front decorative aluminum plate of the thermal insulation integrated board is the thermal insulation integrated board facing layer 14, and the inner part is the thermal insulation integrated board insulation layer 15. The thermal insulation integrated board is formed by high-temperature bonding and pressing, and the male and female joints are filled with high-density polyurethane.

[0070] The thermal insulation integrated panel facing layer 14 can be selected in different colors and coatings according to the design intention of the building facade to form a decorative effect on the building structure facade.

[0071] Insulation of photovoltaic modules, such as Fig. 9 As shown, the exterior is a photovoltaic thermal insulation integrated panel 16, which is formed by high-temperature bonding and pressing, and includes, from the outside to the inside: a front packaging material layer, a power generation material layer, a rear packaging material layer, a rear plate glass layer, a thermal insulation layer, and an inner steel plate.

[0072] In another embodiment of the present invention, in order to further demonstrate the feasibility of the photovoltaic integrated system of the present invention with objective data and provide a social benefit prediction for practical application, a high-rise residential building, such as Fig.11(located in Nanjing, Jiangsu Province, 12 floors above ground, designed in 2003 / built in 2006) as an example, the analysis and research on thermal insulation energy saving and energy consumption optimization and photovoltaic panel application benefits were carried out.

[0073] The energy-saving design parameters of the residential facades are as follows: the heat transfer coefficient of the south and north exterior walls is K = 1.33W / (m 2 ·K), heat transfer coefficient of east and west exterior walls K=1.01W / (m 2 ·K), the insulation material used is 3.0-3.5 cm ZL polystyrene particle insulation slurry, which meets the requirements of the energy-saving design specification "Jiangsu Civil Building Thermal Environment and Energy-saving Design Standard" (DB32 / 478-2001) for heat transfer coefficient during project design.

[0074] However, compared with the current standard "Residential Building Thermal Environment and Energy Saving Design Standard" (DB32 / 4066-2021), for residential buildings with the same number of floors and body coefficient, the external wall heat transfer coefficient K value needs to meet the following requirements: K≤0.8W / (m 2 ·K), which is equivalent to reducing the heat transfer coefficient by about 30% based on the original energy-saving design.

[0075] By comparing the first chapter "General Principles" of the 2002 and 2021 editions of the energy-saving design standards, it can be seen that the energy-saving design target of Jiangsu Province has been increased from 50% for residential buildings to 75%. It can be predicted that now and in the next few decades, the insulation and energy-saving renovation of old urban communities will be urgently needed to improve the living standards of residents.

[0076] The photovoltaic integrated system of the present invention is applied to the house, and a thermal insulation decorative integrated panel is added to the north exterior wall, and a photovoltaic thermal insulation decorative integrated panel is added to the east, west and south exterior walls. The thermal insulation material is EPS polystyrene thermal insulation board 60mm thick. It is expected that the heat transfer coefficient of the south exterior wall can be improved to K = 0.82W / (m 2 ·K), the heat transfer coefficient of the north-facing exterior wall can be improved to K = 0.74W / (m 2 ·K), the heat transfer coefficient of the east and west exterior walls can be improved to K = 0.68W / (m 2 ·K), the overall exterior wall K value can be optimized to 0.76, meeting the current energy-saving design standard K≤0.8W / (m 2 K) requirements.

[0077] Select the southwest corner apartment of the house, such as Fig.12As shown in the figure, as the research object, the area of ​​this apartment is about 96 square meters. The general household is calculated as 4 people per household, and the general electricity consumption is 66-133kwh per month, and about 800-1600kwh for the whole year. The area above and below the south-facing windows that can be used for the installation of thermal insulation photovoltaic integrated panels is about 8 square meters, and the annual power generation is about 1400kwh. The area of ​​the west exterior wall that can be installed with thermal insulation photovoltaic decorative integrated panels is 32.4 square meters, which is apportioned to four households. Each household can install thermal insulation photovoltaic integrated panels with an area of ​​8.1 square meters, and the annual power generation is about 1000kwh. In total, the installation of thermal insulation photovoltaic decorative integrated panels on the exterior facade of the southwest corner apartment can generate about 2400kwh of electricity per year, which can meet the annual electricity needs of the southwest household. (The actual power generation is affected by the sunshine time, installation angle, and whether there is any obstruction around).

[0078] In summary, in the actual work of renovating old urban communities, the photovoltaic integrated system of the present invention can selectively use thermal insulation decorative components or thermal insulation photovoltaic components according to the residents' acceptance of the photovoltaic integration of the facade. On the basis of sharing the same supporting structure, the coexistence and flexible updating and transformation of thermal insulation decorative facades and thermal insulation photovoltaic facades can be achieved, thus solving the problems of aesthetics, thermal insulation, and photovoltaic integration design and construction in the renovation of the facades of old communities.

[0079] It can be seen that the photovoltaic integrated system of the present invention not only improves the utilization rate of solar energy, meets the electricity demand of old communities, provides a stable power supply for community residents, meets daily life and work needs, and improves the living standards of residents; it also better meets the requirements of today's society for energy conservation and environmental protection, reduces carbon dioxide emissions and air pollution, and saves energy costs.

[0080] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
