Description

Technical Field

[0001] The present invention relates to the technical field of building curtain walls, and more specifically, to a photovoltaic-thermal curtain wall component and a curtain wall system. Background Art

[0002] With the intensification of the energy crisis and the improvement of environmental protection awareness, people have begun to actively explore the utilization methods of renewable energy. As a clean and renewable energy source, solar energy has received extensive attention in its development and utilization. Photovoltaic-thermal curtain wall components and curtain wall systems have emerged under this background. By integrating solar panels and heat collection devices, they achieve the dual utilization of solar energy for photovoltaic and solar-thermal purposes, realizing the perfect integration of energy utilization and architectural aesthetics.

[0003] Photovoltaic-thermal curtain walls usually set insulation layers in the air layer between the main structures to maintain the temperature stability inside the building. However, this insulation method has a thermal defect, that is, the vertical and horizontal curtain wall steel keel structures used to install the photovoltaic-thermal curtain wall will become a potential heat loss transfer channel. This situation will not only reduce the overall insulation effect of the exterior wall, but may also force additional insulation materials to be added inside the building to reduce the heat loss inside the building. However, this practice will increase the thickness of the insulation wall and easily occupy the available space inside the building.

[0004] Therefore, this application proposes a photovoltaic-thermal curtain wall component and a curtain wall system to solve the above problems. Summary of the Invention

[0009] In a new embodiment, heat insulation gasket strips are installed on the inner walls of the vertical plate separators and the horizontal plate separators, and heat insulation sealing strips are also installed on the outer walls of the vertical plate separators and the horizontal plate separators.

[0010] In a new embodiment, the heat insulation component includes: fitting parts, symmetrically arranged, installed on the left and right sides at the front of the building structural beam; heat insulation plates, installed on the left and right sides of the building structural beam, the heat insulation plates are connected to the fitting parts through nuts, and the cross-section of the heat insulation plates is L-shaped; glass wool boards, bonded to the inner walls of the heat insulation plates, and hermetically fitted with the walls of the building structural beam, and the cross-section of the glass wool boards is also L-shaped.

[0011] In a new embodiment, the heat insulation component further includes: auxiliary fitting workpieces, hermetically arranged at the top and bottom of the heat insulation plates and installed at the front of the building structural beam; rock wool boards, installed in the middle of the auxiliary fitting workpieces; a drying layer, arranged on the top of the rock wool boards.

[0012] In a new embodiment, heat insulation rock wool is filled between the left and right fitting parts, and the heat insulation rock wool wraps the connectors between the curtain wall vertical keels and the building structural beam.

[0013] In a new embodiment, temperature detectors are installed on the sides of the fitting parts, and temperature measuring long probes are installed at the detection ends of the temperature detectors, and the temperature measuring long probes penetrate through the outer walls of the fitting parts and extend into the internal heat insulation rock wool.

[0014] In a new embodiment, the heat insulation separation component includes: lightweight strip boards, installed at the rear of the curtain wall horizontal keels; heat insulation embedded strips, arranged at the front of the lightweight strip boards and filling the rear space of the curtain wall horizontal keels: a moisture-proof layer, arranged at the rear of the lightweight strip boards.

[0015] In a new embodiment, the caulking assembly includes: a unidirectional air-permeable plate, which is arranged at the front of the horizontal curtain wall keel and is located between the upper and lower curtain walls; a waterproof layer, which is arranged at the rear of the unidirectional air-permeable plate; and a partition heat-insulating layer, which is arranged at the front of the unidirectional air-permeable plate.

[0016] In a new embodiment, the width of the partition heat-insulating layer is greater than the width of the unidirectional air-permeable plate. When the unidirectional air-permeable plate, the waterproof layer, and the partition heat-insulating layer are spliced, the outer sides of the front and back surfaces of the unidirectional air-permeable plate are used to cover the binder at the joints with the waterproof layer and the partition heat-insulating layer.

[0017] A curtain wall system includes the photovoltaic-thermal curtain wall assembly described above and a temperature monitoring module.

The recording unit is used to record all the curtain wall information with temperature leakage phenomena for subsequent data analysis, fault troubleshooting, or maintenance records.

[0018] Beneficial effects: Compared with the prior art, the advantages of the present invention are as follows:

[0019] By setting up a heat-insulating component, the thermal insulation boards installed on the left and right sides of the building structure beam are combined with the auxiliary workpieces and rock wool boards installed at the upper and lower positions of the thermal insulation boards to form a sealed space, thereby wrapping the vertical curtain wall keel of this section and the parts of its connectors with the building structure beam, and preventing the heat inside the building from being absorbed and dissipated by the vertical curtain wall keel.

[0020] Through the heat-insulating component composed of lightweight slats, heat-insulating inlays, and a moisture-proof layer, the heat transfer at the rear of the horizontal curtain wall keel can be blocked, improving the heat insulation effect of the horizontal curtain wall keel. At the same time, the moisture-proof layer provided can effectively prevent moisture from penetrating into the lightweight slats and heat-insulating inlays, resulting in the loss of heat insulation effect.

[0021] By setting up vertical plate partitions and horizontal plate partitions to form a partition heat-insulating frame, that is, an adiabatic component is formed between the vertical and horizontal curtain wall keels and the photovoltaic-thermal curtain wall. Using this adiabatic component to wrap the front, top, bottom, and included angles of the vertical and horizontal curtain wall keels can avoid the loss of heat inside the building through the gaps between the vertical and horizontal curtain wall keels and the photovoltaic-thermal curtain wall. And by matching with the heat-insulating component, the heat transfer contact between the vertical and horizontal curtain wall keels and the building heat is effectively blocked, enhancing the heat insulation effect of the curtain wall assembly.

[0022] By setting the caulking component, on the one hand, during the installation stage of the thermal insulation component, its function is to strengthen the external seal of the horizontal keel and horizontal plate spacer of the curtain wall, preventing external cold air and moisture from entering the building through this gap and affecting the indoor temperature. On the other hand, during the stage when the thermal insulation component is not installed, its function is to ensure the smooth flow of indoor air to the outside and prevent stuffiness inside the building.

Specific embodiments

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0040] By providing a photovoltaic-thermal curtain wall component and a curtain wall system in the embodiments of the present application, the problem that the curtain wall steel keel structure for installing the photovoltaic-thermal curtain wall, as a potential heat loss channel, will reduce the heat insulation effect, forcing additional heat insulation materials to be added inside the building, resulting in the thickening of the wall and occupying the internal space, is solved. When in use, the heat inside the building is prevented from being absorbed and transferred by the vertical curtain wall keel, and while ensuring the normal operation of the curtain wall component, it will not overly occupy the available internal space of the building.

[0041] The technical solutions in the embodiments of the present application for solving the above technical problems are generally as follows:

[0042] Embodiment 1

[0043] Please refer to Figures 1 - 14 , a photovoltaic-thermal curtain wall component, comprising:

[0044] The vertical curtain wall keel 2 is installed on the building structural beam 1 and is assembled in sections, and a plurality of vertical curtain wall keels 2 are distributed in parallel;

[0045] For the horizontal curtain wall keel 3, a plurality of horizontal curtain wall keels 3 are equidistantly installed between two adjacent vertical curtain wall keels 2;

[0046] The thermal insulation component 4 is arranged on the left and right sides at the rear of the vertical curtain wall keel 2 and is also fixedly installed on the left and right sides of the building structural beam 1 for blocking the heat transfer between the vertical curtain wall keel 2 and the heat inside the building;

[0047] The heat insulation component 5 is installed at the rear of the horizontal curtain wall keel 3 for blocking the heat transfer between the horizontal curtain wall keel 3 and the heat inside the building;

[0048] The vertical plate spacer 6 is installed on the left and right sides of the front of the vertical curtain wall keel 2, and concave card slots 7 are provided on the outer sides of the top and bottom of the vertical plate spacer 6;

[0049] The horizontal plate spacer 8 is installed at the top and bottom of the horizontal curtain wall keel 3, and the horizontal plate spacer 8 is clamped with the vertical plate spacer 6 through the concave card slot 7;

[0050] The curtain wall 11 is installed in front of the vertical plate spacer 6 and the horizontal plate spacer 8;

[0051] A caulking component 12 is also filled between the upper and lower curtain walls 11. Outer pressure aluminum strips 13 are provided on both the left and right sides of the curtain wall 11, and the outer pressure aluminum strips 13 are installed in front of the vertical curtain wall keel 2, and a moisture-proof sealing strip 14 is pasted on the rear wall of the outer pressure aluminum strip 13.

[0052] In this embodiment, please refer to Figures 1 - 14 As shown, the specific installation process of the photovoltaic and solar thermal curtain wall component is as follows:

[0053] First step: First, determine the position of the external wall building structure beam 1, and then install the vertical curtain wall keel 2 in sections through metal connectors. After the installation is completed, determine the installation position of the horizontal curtain wall keel 3 according to the width of the installed curtain wall 11, so as to form a frame-shaped support structure for installing the curtain wall 11 by the left and right vertical curtain wall keels 2 and the upper and lower horizontal curtain wall keels 3;

[0054] Second step: Install the insulation board 402 in the insulation component 4 on the left and right sides of the building structure beam 1 through the fitting 401, then fill the insulation rock wool 15 between them, and then match the upper and lower positions of the insulation board 402 with the auxiliary fitting 404 and the rock wool board 405 also installed on the building structure beam 1 for top and bottom sealing, so as to wrap the rear part of the vertical curtain wall keel 2 and the part of its connector with the building structure beam 1, and prevent the heat inside the building from being absorbed and transferred by the vertical curtain wall keel 2;

[0055] Third step: Continuing from the second step, the back surface (the side facing the building space) of the horizontal curtain wall keel 3 can be filled with heat insulation through the light strip 501, the heat insulation inlay strip 502, and the moisture-proof layer 503 in the heat insulation component 5, so as to prevent heat from being dissipated along the horizontal curtain wall keel 3;

[0056] Step 4: First, install the vertical plate partition 6 on the side of the vertical keel 2 of the curtain wall, and then insert and fix the horizontal plate partition 8 through the concave slot 7, and then the horizontal plate partition 8 half-wraps the horizontal keel 3 of the curtain wall, so that a heat insulation layer is formed between the vertical keel 2 of the curtain wall, the horizontal keel 3 of the curtain wall and the curtain wall 11, avoiding direct installation contact between the vertical keel 2 of the curtain wall and the horizontal keel 3 of the curtain wall and the curtain wall 11, avoiding heat transfer, and the front of the insulation board 402 in the insulation assembly 4 conflicts with the rear of the vertical plate partition 6 and the horizontal plate partition 8, further ensuring the insulation and wrapping effect of the vertical keel 2 of the curtain wall;

[0057] Step 5. After the curtain wall 11 is installed, the exterior of the curtain wall 11 can be pressed and fixed by installing an externally pressed aluminum strip 13 and a moisture-proof sealing strip 14 on the front of the curtain wall vertical keel 2. Finally, the caulking assembly 12 is directly installed on the upper and lower curtain walls 11, thereby completing the installation process of the entire curtain wall assembly.

[0058] In summary, the photovoltaic thermal curtain wall assembly isolates the heat transfer between the curtain wall vertical purlins 2, the curtain wall horizontal purlins 3 and the internal space of the building, ensuring that the temperature in the building does not dissipate, and also blocks the heat transfer of the connection installation between the curtain wall vertical purlins 2, the curtain wall horizontal purlins 3 and the curtain wall 11. The installation is simple and does not occupy too much building space. It has better insulation effect in buildings in cold areas, and will not affect the solar energy absorption of the photovoltaic thermal curtain wall assembly. Secondly, the above insulation structure between the curtain wall vertical purlins 2, the curtain wall horizontal purlins 3 and the curtain wall 11 can be disassembled and installed according to regional temperature changes, and is more flexible to use.

[0059] For further information, see Figure 3 , Figure 4 , Figure 5 , Figure 12 and Figure 13 The inner walls of the vertical plate partitions 6 and the horizontal plate partitions 8 are both installed with insulation pads 9, and the outer walls of the vertical plate partitions 6 and the horizontal plate partitions 8 are also installed with insulation sealing strips 10. By installing insulation pads 9 on the inner wall parts of the vertical plate partitions 6 and the horizontal plate partitions 8, the insulation pads 9 are made of insulation materials. As the position where the vertical plate partitions 6 and the horizontal plate partitions 8 contact the surfaces of the curtain wall vertical purlins 2 and the curtain wall horizontal purlins 3, possible tiny gaps can be filled and sealed to prevent external cold air or hot air from entering the interior of the building. By installing insulation sealing strips 10 on the outer wall parts of the vertical plate partitions 6 and the horizontal plate partitions 8, the curtain wall 11 can be sealed and installed on the vertical plate partitions 6 and the horizontal plate partitions 8 to ensure the sealing after mutual installation.

[0060] Example 2

[0061] See also Figures 6 - 9 , the thermal insulation component 4 comprises:

[0062] The fitting 401 is symmetrically arranged and installed on the left and right sides of the front part of the building structural beam 1;

[0063] The thermal insulation board 402 is installed on the left and right sides of the building structural beam 1. The thermal insulation board 402 is connected to the fitting 401 through nuts, and the cross-section of the thermal insulation board 402 is L-shaped;

[0064] The glass wool board 403 is bonded to the inner wall of the thermal insulation board 402, is hermetically fitted to the wall of the building structural beam 1, and the cross-section of the glass wool board 403 is also L-shaped.

[0065] In this embodiment, please refer to Figures 6 - 9 As shown, the fitting 401, as a connecting piece between the thermal insulation component 4 and the building structural beam 1, plays a role in supporting and fixing the thermal insulation board 402. The thermal insulation board 402 can form a thermal insulation barrier between the building structural beam 1 and the indoor environment. Secondly, the cross-section of the thermal insulation board 402 is L-shaped, which can be hermetically matched with the subsequent vertical board spacer 6 and horizontal board spacer 8 to better wrap the curtain wall vertical keel 2 and the sealing performance of the connecting piece between the curtain wall vertical keel 2 and the building structural beam 1. Secondly, the inner wall of the thermal insulation board 402 is also bonded with the glass wool board 403. On the one hand, it prevents the internal moisture of the building structural beam 1 from penetrating into the thermal insulation board 402, and on the other hand, it can better make the thermal insulation board 402 in contact and sealed installation with the building structural beam 1, further enhancing the thermal insulation performance of the thermal insulation component 4. At the same time, the glass wool board 403 has excellent thermal insulation performance and fire resistance, and can effectively prevent the transfer of heat and the spread of fire.

[0066] Furthermore, please refer to Figure 8 , the thermal insulation component 4 further includes:

[0067] The auxiliary fitting 404 is hermetically arranged at the top and bottom of the thermal insulation board 402 and is installed at the front part of the building structural beam 1;

[0068] The rock wool board 405 is installed in the middle of the auxiliary fitting 404;

[0069] The drying layer 406 is arranged on the top of the rock wool board 405.

[0070] In this embodiment, please refer to Figure 8As shown, the auxiliary fitting workpiece 404 functions to cooperate with the fitting part 401 and the thermal insulation board 402, so that the thermal insulation boards 402 installed on the left and right sides of the building structural beam 1 cooperate with the auxiliary fitting workpieces 404 and the rock wool boards 405 installed on the upper and lower parts to form a sealed space, and thermal insulation rock wool 15 is filled in this sealed space. The rock wool board 405 is a high-performance thermal insulation material with excellent fire prevention, sound insulation and thermal insulation properties. It wraps the curtain wall vertical keel 2 and its connecting part, fills and isolates the curtain wall vertical keel 2, reduces the transfer of heat in the building through the curtain wall vertical keel 2, and there is also a drying layer 406 on the rock wool board 405 to prevent moisture from penetrating into the thermal insulation rock wool 15, keep the thermal insulation rock wool 15 dry and stable, and protect the performance of the rock wool board 405 and the entire thermal insulation component 4.

[0071] Further, please refer to Figure 9 , thermal insulation rock wool 15 is filled between the left and right fitting parts 401, and the thermal insulation rock wool 15 wraps the connecting part between the curtain wall vertical keel 2 and the building structural beam 1. The filled thermal insulation rock wool 15 can cut off the heat bridge transfer of the curtain wall vertical keel 2, which is both heat-insulating and energy-saving, enhances the structural stability, improves the moisture-proof and corrosion-proof properties of the building structural beam 1, and improves the building energy efficiency.

[0072] Further, please refer to Figure 10 , temperature detectors 16 are installed on the sides of the fitting part 401, and temperature measuring long probes 17 are installed at the detection ends of the temperature detectors 16, and the temperature measuring long probes 17 penetrate through the outer wall of the fitting part 401 and extend into the internal thermal insulation rock wool 15.

[0073] By installing the temperature detector 16 on the side of the fitting part 401 and extending it into the internal thermal insulation rock wool 15 with the temperature measuring long probe 17, a temperature monitoring function is realized. The temperature detector 16, as an intelligent sensor, can monitor the temperature change of the internal thermal insulation rock wool 15. When the temperature remains constant, it indicates that the internal thermal insulation rock wool 15 is in a good thermal insulation state. On the contrary, if the temperature of the internal thermal insulation rock wool 15 decreases, it means that its thermal insulation performance may decline. In addition, the temperature detector 16 also has the ability to detect the external temperature difference. Two adjacent temperature detectors 16 can respectively measure and record the left and right temperature difference data of the curtain wall 11 between them. Through the local temperature difference, it is beneficial to capture and monitor the air leakage problem of the curtain wall 11.

[0074] Embodiment 3

[0075] Please refer to Figure 2 and Figure 14 , the heat insulation component 5 includes:

[0076] The lightweight panel 501 is installed at the rear of the curtain wall horizontal keel 3;

[0077] The heat-insulating insert strip 502 is arranged at the front part of the lightweight strip board 501 and fills the rear space of the curtain wall horizontal keel 3:

[0078] The moisture-proof layer 503 is arranged at the rear part of the lightweight strip board 501.

[0079] In this embodiment, please refer to Figure 2 and Figure 14 As shown, through the heat insulation component 5 composed of the lightweight strip board 501, the heat-insulating insert strip 502 and the moisture-proof layer 503, the heat transfer at the rear of the curtain wall horizontal keel 3 can be blocked, improving the heat insulation effect of the curtain wall horizontal keel 3. At the same time, the arranged moisture-proof layer 503 can effectively prevent moisture from penetrating into the lightweight strip board 501 and the heat-insulating insert strip 502, avoiding the loss of heat insulation effect.

[0080] Furthermore, please refer to Figure 3 and Figure 11 , the caulking component 12 includes:

[0081] The one-way air-permeable board 1201 is arranged at the front part of the curtain wall horizontal keel 3 and is located between the upper and lower curtain walls 11;

[0082] The waterproof layer 1202 is arranged at the rear of the one-way air-permeable board 1201;

[0083] The partition heat-insulating layer 1203 is arranged at the front of the one-way air-permeable board 1201.

[0084] The setting of the caulking component 12, on the one hand, when the heat insulation component 4, the vertical board spacer 6 and the horizontal board spacer 8 are all in the installed state, the main function of the caulking component 12 in this case is to seal the space between the upper and lower curtain walls 11, strengthening the external sealing guarantee at the curtain wall horizontal keel 3 and the horizontal board spacer 8, preventing external cold air from entering the building through this gap and affecting the indoor temperature of the building. On the other hand, when the heat insulation component 4, the vertical board spacer 6 and the horizontal board spacer 8 are not in the installed state, through the one-way air-permeable board 1201 in the caulking component 12, it can ensure the smooth flow of the air inside the building to the outside, preventing internal stuffiness. In addition, a waterproof layer 1202 is added at the rear of the one-way air-permeable board 1201 to prevent the moisture inside the building from penetrating into the one-way air-permeable board 1201 and affecting its air-permeable performance, protecting the stability and durability of the curtain wall 11 structure.

[0085] Furthermore, please refer to Figure 11As shown, the width of the partition thermal insulation layer 1203 is greater than the width of the one-way breathable board 1201. When the one-way breathable board 1201, the waterproof layer 1202, and the partition thermal insulation layer 1203 are spliced, the outer sides of the front and back of the one-way breathable board 1201 are used to cover the adhesive at the joints with the waterproof layer 1202 and the partition thermal insulation layer 1203. Designing the width of the partition thermal insulation layer 1203 to be greater than the width of the one-way breathable board 1201 aims to effectively block the intrusion of external cold air. Moreover, the splicing joints of the one-way breathable board 1201, the waterproof layer 1202, and the partition thermal insulation layer 1203 are covered with adhesive, further reducing the risk of air and moisture penetrating through the joints, thereby enhancing the airtightness of the caulking assembly 12 and effectively reducing the entry of external air, moisture, and impurities.

The temperature monitoring module 18 includes a monitoring unit, an alarm unit, and a recording unit; the monitoring unit is used to continuously receive and process temperature detection data from the temperature detector 16, and is used to monitor the temperature change of each section of the thermal insulation rock wool 15 and the left-right temperature difference data of the curtain wall 11 between two adjacent temperature detectors 16; the alarm unit, the temperature detectors 16 work in a series mode, and this unit can accurately identify and locate the area of the curtain wall 11 where the temperature is abnormal and give an alarm; the recording unit is used to record all the information of the curtain wall 11 where the temperature leakage phenomenon occurs for subsequent data analysis, fault troubleshooting, or maintenance records.

[0088] In summary, through real-time monitoring and early warning, the system can timely discover and handle potential energy efficiency problems and safety hazards, thereby ensuring the overall energy efficiency and safety of the curtain wall assembly, which helps to extend the service life of the curtain wall assembly, reduce the downtime and maintenance costs caused by faults, and at the same time improve the overall energy efficiency and environmental protection performance of the building.
