Description

Technical Field

[0001] This invention relates to the field of exterior wall panel technology, specifically to a detachable cooling and heating exterior wall panel and its installation method. Background Technology

[0002] With the increasing demand for building energy conservation and refined indoor environmental control, the efficient integration of building envelope and energy supply system has become a key direction for reducing building operating energy consumption and improving indoor thermal comfort. In conventional building envelope energy conservation, building exterior walls mostly use traditional passive static thermal insulation measures such as EPS / XPS. However, these measures have a series of application problems:

[0003] 1) Although the passive static insulation measure alleviates the building load to some extent, the building still relies on active high-quality terminal equipment such as central air conditioning, radiators, fan coil units, and individual air conditioners to achieve its heating and cooling.

[0004] 2) The energy supply path for internal heating and cooling still has problems such as separation of the "source-network-end" link, large system inertia, and lag in regulation. In particular, for non-external enclosure structures such as interior partitions and ceilings, their thermal performance is usually designed only according to the requirements of heat insulation and sound insulation, and they do not have the ability to actively supply energy or store energy for regulation, and cannot dynamically respond to changes in room load.

[0005] 3) Traditional passive static insulation measures for exterior walls cause a series of problems such as peeling of the exterior wall skin, significant fire hazards, and space occupation;

[0006] 4) Although traditional passive insulation measures for exterior walls have achieved a certain degree of energy saving, the implicit energy and implicit carbon emissions they generate far outweigh their energy-saving and carbon-reduction effects.

[0007] Therefore, this technical field advocates and promotes active thermal insulation technology. Research has found that by installing active heating unit panels on the exterior walls of buildings, a dynamic thermal barrier can be formed between the indoor and outdoor environments. Compared with traditional static insulation measures, this type of active thermal insulation uses readily available low-grade renewable energy as its energy source, injecting it into the wall to form a dynamic thermal barrier. This dynamic thermal barrier can be dynamically adjusted according to different climate zones and building load requirements to significantly reduce or eliminate indoor heat loss, and may even completely eliminate the load generated by the wall. In this type of technology, some research has attempted to pre-embed capillary tubes, PE-X pipes, etc., in the walls or floors to form a radiant terminal system, but several limitations still exist.

[0008] 1) Once such system piping is embedded in the structural layer, it is difficult to inspect or modify, and it is too tightly coupled with the building structure, which is not conducive to the renovation of existing buildings and the flexible division of space.

[0009] 2) There are often problems such as high thermal resistance between pipes and walls, slow response speed, and easy condensation on the surface. In addition, the heat output of the system is limited by the density and depth of the buried pipes, making it difficult to achieve precise temperature control in local spaces.

[0010] 3) The installation and construction methods are difficult to match the development needs of prefabricated installation industrialization construction;

[0011] 4) Uneven heat distribution reduces indoor comfort and system energy efficiency;

[0012] In view of the drawbacks of the traditional passive static thermal insulation measures for walls and the conventional active external wall heating unit panel technology, the present invention provides a detachable cooling and heating external wall panel and its installation method. Summary of the Invention

[0013] In order to solve the technical problems existing in the prior art, the present invention provides a detachable cooling and heating exterior wall panel and its installation method.

[0014] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a detachable cooling and heating exterior wall panel, comprising a frame assembly, a heating module, and an insulation and decorative surface;

[0015] The frame assembly is fixed to the wall surface by bolts, several sets of heating modules are installed at intervals inside the frame assembly, and the heat insulation decorative surface is installed on the surface of the frame assembly.

[0016] Preferably, the frame assembly includes a top plate, a bottom plate, a keel frame module, and a closing plate. The top plate and the bottom plate are respectively installed on the top and bottom of the wall surface. Several sets of the keel frame modules are installed between the top plate and the bottom plate at intervals. Two sets of the closing plates are respectively installed at both ends of the top plate and the bottom plate.

[0017] Preferably, the keel frame module includes a slide rail keel, a top dry-hanging component, a middle dry-hanging component, and a bottom dry-hanging component. The slide rail keel is installed between the top plate and the bottom plate. The slide rail keel has a dry-hanging component slide rail inside. The top dry-hanging component, the middle dry-hanging component, and the bottom dry-hanging component are respectively installed at the top, middle, and bottom positions inside the dry-hanging component slide rail.

[0018] Preferably, the heating module includes several sets of vertically combined heating unit plates, water supply pipes and return pipes. The heating unit plates are engaged between two sets of keel frame modules. The water supply pipes and return pipes are respectively located inside the top plate and the bottom plate. The water inlet and water outlet of the heating unit plate are respectively connected to the water supply pipes and the return pipes.

[0019] Preferably, several of the heating unit panels are vertically arranged, and each heating unit panel includes a reinforced heat-conducting layer. A heat-insulating frame is provided on one side of the reinforced heat-conducting layer, and a heat-insulating layer is provided on the other side of the reinforced heat-conducting layer.

[0020] Preferably, the interior of the enhanced heat-conducting layer has U-shaped grooves for embedded tubes, and embedded tubes are arranged inside the grooves. The inlet and outlet of the embedded tubes are respectively located at the top and bottom of the enhanced heat-conducting layer. In the two sets of enhanced heat-conducting layers, the outlet of the upper embedded tube is connected to the inlet of the lower embedded tube, the inlet of the upper embedded tube is connected to the water supply pipe, and the outlet of the lower embedded tube is connected to the return pipe. A radiant panel is attached to one side surface of the enhanced heat-conducting layer, and the radiant panel has a notch that matches the embedded tube groove.

[0021] Preferably, the interior of the heat insulation frame is provided with several sets of filling grooves that are perpendicular to the heat insulation frame and parallel to each other, and each set of filling grooves is filled with filling cotton.

[0022] Preferably, an inner heat insulation board is attached to one side of the heat insulation layer, and an outer heat insulation board is attached to the other side of the heat insulation layer.

[0023] Preferably, the thermal insulation decorative surface includes several panel modules, which together with the top dry-hanging component, the middle dry-hanging component and the bottom dry-hanging component form the thermal insulation decorative surface.

[0024] A method for installing a detachable cooling and heating exterior wall panel includes the following steps:

[0025] Step S1: Install the base plate, install the return water pipe inside the base plate, and install several sets of keel frame modules at intervals inside the base plate.

[0026] Step S2: Install the heating unit plate between adjacent keel frame modules, and connect the water outlet of the embedded pipe in the heating unit plate at the bottom to the return water pipe.

[0027] Step S3: Set a set of bottom dry-hanging parts in the dry-hanging parts slide rail of each set of keel frame modules, install a set of panel modules between horizontally adjacent bottom dry-hanging parts, and then set a set of middle dry-hanging parts in each set of dry-hanging parts slide rail. The middle dry-hanging parts work with the bottom dry-hanging parts to fix the panel modules. Set another set of panel modules between horizontally adjacent middle dry-hanging parts. Continue to install middle dry-hanging parts in each set of dry-hanging parts slide rail. Vertically adjacent dry-hanging parts slide rails fix another set of panel modules. Repeat the operation until the panel modules in the top area are installed.

[0028] Step S4: Install the top dry-hanging component into the dry-hanging component slide rail. The top dry-hanging component, together with the middle dry-hanging component, fixes the uppermost panel module. At this time, the panel module forms a heat-insulating decorative surface.

[0029] Step S5: Install a top plate on the top of the keel frame module and install a water supply pipe inside the top plate. Connect the water inlet of the embedded pipe in the heating unit plate located at the top to the water supply pipe.

[0030] Step S6: Install a set of sealing panels between each end of the top and bottom plates to form a complete closed cooling and heating exterior wall panel.

[0031] Step S7: During disassembly, prioritize removing the two sets of closed plates and the top plate, disconnect the water inlet of the embedded pipe from the water supply pipe, and then remove the top dry-hanging parts and the middle dry-hanging parts in sequence. For each layer removed, remove the corresponding panel module until all panel modules are removed.

[0032] From one side to the other, remove each set of keel frame modules in sequence. Each time a set of keel frame modules is removed, the fixing of a set of heating unit panels is released. At this time, remove the corresponding heating unit panel and disconnect the connection between the return water pipe and the outlet of the heating unit panel until all keel frame modules and heating unit panels are completely removed.

[0033] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0034] 1. To achieve the tiered utilization of low-grade energy and reduce building operating energy consumption, this invention introduces the low-grade heat source after one or more heat releases into the embedded tube of the heating unit plate. The low-grade heat source forms an active dynamic thermal barrier on the building's exterior wall, which can reduce heat exchange between the indoor and outdoor environments, reduce or even eliminate the heating and cooling load generated by the wall, thereby improving energy utilization and reducing the building's dependence on high-grade heating and cooling sources and traditional air conditioning terminal equipment.

[0035] 2. Improve heat exchange uniformity, avoid local heat accumulation and accelerate wall thermal response. This invention strengthens the heat-conducting layer to rapidly diffuse the heat carried by the low-grade heat source to the surroundings and further uniformly transfer it to the surface of the radiant panel. This creates a more uniform heat exchange between the radiant panel and the wall, reduces the phenomenon of excessively high or low local temperatures near the embedded tube, avoids the decrease in heat exchange efficiency caused by heat accumulation at the embedded tube, improves the uniformity of temperature distribution on the wall panel surface and the speed of cooling and heating response, thereby efficiently reducing or eliminating indoor heat loss and further realizing the efficient cascade utilization of energy.

[0036] 3. Reduce the heat transfer resistance between the pipes and the wall panel and improve the cooling and heating efficiency. The present invention sets a pipe groove adapted to the embedded pipe inside the reinforced heat-conducting layer and sets a radiant panel that matches the pipe groove on the surface of the reinforced heat-conducting layer. This forms a continuous heat transfer path between the embedded pipe, the reinforced heat-conducting layer and the radiant panel, which can shorten the heat transfer distance, expand the effective heat exchange area, reduce the heat transfer resistance caused by the large burial depth and insufficient contact of traditional pre-embedded pipes, and improve the performance of this type of wall and the utilization efficiency of low-grade cold and heat sources.

[0037] 4. The modular structure reduces the difficulty of installation, maintenance and replacement. The invention divides the heating module into several heating unit panels that are combined with each other. Each heating unit panel can be installed between the keel frame modules as a relatively independent functional unit. When some heating unit panels, embedded pipes or heat insulation materials are damaged or their performance degrades, the corresponding parts can be removed and replaced individually without damaging or replacing the entire wall, thereby reducing maintenance workload and repair costs and extending the overall service life of the exterior wall panels.

[0038] 5. Low-cost material insulation, sealing, and installation compensation: This invention sets multiple sets of spaced filling grooves inside the insulation frame, and fills the filling grooves with soft, compressible, and resilient filling cotton. The filling cotton can separate the air flow space inside the frame, suppress natural convection and chimney effect, improve the equivalent thermal resistance of the wall panel edge area, and reduce heat transfer caused by edge thermal bridges. At the same time, the filling cotton can adapt to the unevenness of the wall surface and installation errors, compensate for the flatness deviation of the wall, and make the insulation frame fit tightly with the wall, reduce installation gaps and air infiltration, thereby improving the insulation, sealing, and installation adaptability of the wall panel.

[0039] 6. Forming a directional heat transfer composite insulation structure improves long-term thermal insulation performance. This invention forms a closed composite insulation system through an inner insulation board, an insulation layer, and an outer insulation board, which covers and insulates the reinforced heat-conducting layer. This allows more heat to be transferred towards the radiating panel and the target wall, reducing energy loss to non-target directions. At the same time, the inner and outer insulation boards support and protect the insulation material, reducing the entry of outside air and moisture into the insulation layer and delaying the degradation of the insulation material's performance. When the insulation material reaches the end of its service life, it can be replaced by disassembling the corresponding heating unit board, improving the structure's durability and ease of maintenance.

[0040] 7. Combining cooling and heating, insulation, and decoration functions, this invention improves system integration. The heating module is set inside the frame assembly, and an insulation and decoration surface composed of multiple panel modules is set on the outside of the frame assembly. The top and bottom plates can also accommodate water supply pipes and return pipes respectively, so that the cooling and heating pipes, insulation structure, load-bearing structure and decoration structure form an integrated exterior wall panel, reducing exposed pipes and additional decoration construction, making the wall appearance flat and complete, and improving the functional integration of the building envelope.

[0058] The above and other technical features and advantages of the present invention will be further described below with reference to the accompanying drawings and embodiments. However, the following embodiments are merely preferred embodiments of the present invention and are not exhaustive.

[0059] Example 1:

[0060] like Figures 1-11 As shown, the present invention provides a detachable cooling and heating exterior wall panel, including a frame assembly 1, a heating module 2, and an insulation decorative surface 3;

[0061] The frame assembly 1 is fixed to the wall surface by bolts, several sets of heating modules 2 are installed at intervals inside the frame assembly 1, and the heat-insulating decorative surface 3 is installed on the surface of the frame assembly 1.

[0062] The frame component 1 includes a top plate 11, a bottom plate 12, a keel frame module 13, and a closing plate 14. The top plate 11 and the bottom plate 12 are respectively installed on the top and bottom of the wall surface. Several sets of keel frame modules 13 are installed between the top plate 11 and the bottom plate 12 at intervals. Two sets of closing plates 14 are respectively installed at both ends of the top plate 11 and the bottom plate 12. The top plate 11, the bottom plate 12, and the keel frame module 13 cooperate to limit the heating module 2 and the thermal insulation decorative surface 3, forming a flat and closed exterior wall panel. While serving as decoration, it also forms a continuous dynamic thermal barrier on the concrete exterior wall surface.

[0063] The keel frame module 13 includes a slide rail keel 131, a top dry-hanging component 132, a middle dry-hanging component 133, and a bottom dry-hanging component 134. The sliding keel 131 is installed between the top plate 11 and the bottom plate 12. It has a dry-hanging component slide 1311 inside. The top dry-hanging component 132, the middle dry-hanging component 133 and the bottom dry-hanging component 134 are respectively set at the top, middle and bottom positions of the dry-hanging component slide 1311. Through the layered fixing effect of the top dry-hanging component 132, the middle dry-hanging component 133 and the bottom dry-hanging component 134, the heating unit panels 21 at different installation positions can be limited and connected, so that multiple heating unit panels 21 can be spliced ​​to form a complete heating wall panel. The heating unit panels 21 adopt a modular independent structure and are spliced ​​and installed through the keel module 13. Each heating unit panel 21 is an independent functional unit. After the sealing connection of the water inlet and outlet of the heating unit panel 21 is completed, no additional overall sealing treatment is required between the unit panels, thereby reducing the installation difficulty and improving the convenience of later maintenance and replacement.

[0064] The heating module 2 includes several sets of vertically combined heating unit plates 21, water supply pipes 22, and return water pipes 23. The heating unit plates 21 are snapped between two sets of keel frame modules 13. The water supply pipes 22 and return water pipes 23 are respectively located inside the top plate 11 and the bottom plate 12. The inlet and outlet of the heating unit plate 21 are connected to the water supply pipes 22 and 23, respectively. The water supply pipes 22 provide the heating unit plate 21 with a low-grade heat source for heating. The low-grade heat source completes heat exchange inside the heating unit plate 21, forming a thermal barrier. The low-grade heat source that has completed heat exchange enters the return water pipe 23 for recycling. The interface between the inlet and outlet of the heating unit plate 21 and the heat insulation frame 212 of the heating unit plate 21 is sealed with sealant. The sealant sealing method is only one in this embodiment. In specific implementation, corresponding installation methods can be adopted.

[0065] Several heating unit panels 21 are vertically assembled. Each heating unit panel 21 includes a reinforced heat-conducting layer 211. A heat-insulating frame 212 is provided on one side of the reinforced heat-conducting layer 211, and a heat-insulating layer 213 is provided on the other side of the reinforced heat-conducting layer 211.

[0066] The interior of the enhanced heat-conducting layer 211 has U-shaped tube grooves 2111, and tubes 2112 are arranged inside the tube grooves 2111. The inlet and outlet of the tubes 2112 are respectively located at the top and bottom of the enhanced heat-conducting layer 211. In the two sets of enhanced heat-conducting layers 211, the outlet of the upper tube 2112 is connected to the inlet of the lower tube 2112 through a standard quick-connect fitting (such as the standard quick-connect fitting PicappoPPSOC20 manufactured by Toei Corporation of Japan). The inlet of the upper tube 2112 is connected to the water supply pipe 22 through a standard quick-connect fitting, and the outlet of the lower tube 2112 is connected to the return pipe 23 through a standard quick-connect fitting. In this embodiment, a standard quick-connect connector is used for connection, but it is not limited to this. In specific implementation, other suitable sealing methods can be selected according to actual needs to ensure the sealing and safe operation of the embedded tube 2112. A radiant panel 2113 is attached to one side surface of the enhanced heat-conducting layer 211. The radiant panel 2113 has a notch that matches the embedded tube groove 2111. After the low-grade heat source enters the embedded tube 2112, the enhanced heat-conducting layer 211 evenly distributes the heat from the low-grade heat source to the surface of the radiant panel 2113. The heat exchange by the radiant panel 2113 can achieve uniform heat exchange, and the wall can be heated evenly. It also avoids the problem of heat accumulation at the embedded tube 2112 reducing the heat exchange efficiency.

[0067] The interior of the heat insulation frame 212 has several sets of filling grooves 2121 perpendicular to and parallel to each other. Each set of filling grooves 2121 is filled with filling cotton 2122. When the heat insulation frame 212 is in close contact with the wall, the filling grooves 2121 and the filling cotton 2122 can form multiple spaced local thermal resistance areas at the edge of the wall panel, which can segmentally block the heat flow transmitted along the heat insulation frame 212. The filling cotton 2122 has a large airflow resistance, which can separate the continuous air flow space inside the heat insulation frame 212, making it difficult for the internal air to form a complete natural convection circulation. This inhibits the flow of hot air along the height of the wall panel and its accumulation at the top, reducing the phenomenon of uneven temperature distribution in the upper and lower areas of the wall panel. Since the thermal conductivity of the filling cotton 2122 is lower than the overall heat exchange capacity when the air undergoes natural convection, the filling cotton 2122 in the filling grooves 2121 can improve the equivalent thermal resistance of the heat insulation frame 212 area and reduce the speed at which heat is transferred outward along the edge of the wall panel.

[0068] The filling cotton 2122 also has compression resilience, which can undergo elastic deformation during the installation of the heat insulation frame 212 and the wall to compensate for the errors in the flatness of the wall surface and the installation position, so that the filling cotton 2122 and the wall are closely attached to form a flexible seal. This flexible seal can reduce the installation gap between the heat insulation frame 212 and the wall, reduce air infiltration and hot and cold air crossflow, and further weaken the chimney effect generated by the upward flow of hot air along the frame.

[0069] In addition, the filling cotton 2122 inside the multiple filling grooves 2121 can form a continuous thermal resistance layer, so that the outer perimeter of the thermal insulation frame 212 forms a complete thermal insulation layer, effectively blocking the leakage of heat from the inside of the wall panel to the edge, improving the overall thermal integrity of the outer envelope structure. At the same time, compared with the traditional hollow tube structure, the filling cotton 2122 can further reduce the thermal bridge effect of the frame and improve the operating efficiency of the cooling and heating wall panel.

[0070] An inner heat insulation board 2131 is attached to one side of the heat insulation layer 213, and an outer heat insulation board 2132 is attached to the other side. The heat insulation layer 213, together with the inner heat insulation board 2131 and the outer heat insulation board 2132, forms a closed composite heat insulation structure. This effectively covers the reinforced thermal conductive layer 211, ensuring that the heat insulation material filled in the heat insulation layer 213 is always in a stable sealed environment. This effectively prevents outside air and moisture from entering the interior of the reinforced thermal conductive layer 211, reduces the rate of performance degradation of the heat insulation material, and helps maintain the stable thermal performance of the heat insulation layer 213 over a long period of time. Furthermore, when the heat insulation material reaches the end of its service life, only the corresponding wall panel needs to be removed to clean the internal heat insulation material. Replacement is possible without replacing the entire wall structure, improving maintenance convenience and service life. The inner insulation board 2131, the insulation layer 213, and the outer insulation board 2132 together form a three-layer composite insulation system. The inner insulation board 2131 is mainly used to block the direct heat transfer from the reinforced heat-conducting layer 211 to the wall, reducing heat diffusion inward. The insulation layer 213, as the main thermal resistance area, achieves heat barrier through the internal insulation material. The outer insulation board 2132 further reduces the continued heat transfer after penetrating the insulation layer 213 and protects and supports the internal insulation material, thereby improving the stability and durability of the overall insulation structure.

[0071] The thermal insulation decorative surface 3 includes several panel modules 31. The panel modules 31 are connected by the cooperation of the top dry-hanging component 132, the middle dry-hanging component 133 and the bottom dry-hanging component 134 to form the thermal insulation decorative surface 3. During the installation process, due to the assembly gap between each panel module 31, a certain gap may be formed. In order to improve the overall sealing performance, sealant can be used to fill and seal the gap. In this embodiment, the method of filling with sealant is used, but it is not limited to this. In the specific implementation process, other suitable sealing methods can be selected according to actual needs.

[0072] A method for installing and removing a detachable cooling and heating exterior wall panel includes the following steps:

[0073] Step S1: Install the base plate 12, install the return water pipe 23 inside the base plate 12, and install several sets of keel frame modules 13 at intervals inside the base plate 12.

[0074] Step S2: Install the heating unit plate 21 between adjacent keel frame modules 13, and connect the water outlet of the embedded pipe 2112 in the bottom heating unit plate 21 to the return water pipe 23.

[0075] Step S3: Set a set of bottom dry-hanging parts 134 in the dry-hanging parts slide 1311 of each set of keel frame modules 13, install a set of panel modules 31 between horizontally adjacent bottom dry-hanging parts 134, and then set a set of middle dry-hanging parts 133 in each set of dry-hanging parts slide 1311. The middle dry-hanging parts 133 cooperate with the bottom dry-hanging parts 134 to fix the panel modules 31. Set another set of panel modules 31 between horizontally adjacent middle dry-hanging parts 133, and continue to install middle dry-hanging parts 133 in each set of dry-hanging parts slide 1311. Vertically adjacent dry-hanging parts slide 1311 fix another set of panel modules 31. Repeat the operation until the panel modules 31 in the top area are installed.

[0076] Step S4: Install the top dry-hanging component 132 into the dry-hanging component slide 1311. The top dry-hanging component 132, together with the middle dry-hanging component 133, fixes the uppermost panel module 31. At this time, the panel module 31 forms the heat-insulating decorative surface 3.

[0077] Step S5: Install a top plate 11 on the top of the keel frame module 13, and install a water supply pipe 22 inside the top plate 11. Connect the water inlet of the embedded tube 2112 in the heating unit plate 21 located at the top to the water supply pipe 22. The water supply pipe 22 is connected to the external low-grade heat source supply pipe. The external low-grade heat source enters the embedded tube 2112 through the water supply pipe 22.

[0078] Step S6: Install a set of sealing plates 14 between each end of the top plate 11 and the bottom plate 12 to form a complete closed cooling and heating exterior wall panel.

[0079] Step S7: During disassembly, prioritize removing the two sets of closed plates 14 and the top plate 11, disconnect the water inlet of the embedded pipe 2112 from the water supply pipe 22, and then remove the top dry-hanging component 132 and each set of middle dry-hanging components 133 in sequence. For each layer removed, remove the corresponding panel module 31 until all panel modules 31 are removed.

[0080] From one side to the other, remove each set of keel frame modules 13 in sequence. Each time a set of keel frame modules 13 is removed, the fixing of a set of heating unit plates 21 is released. At this time, the corresponding heating unit plate 21 is removed, and the connection between the return water pipe 23 and the outlet of the heating unit plate 21 is disconnected, until all keel frame modules 13 and heating unit plates 21 are completely removed.

[0081] Example 2:

[0082] This embodiment describes the application and performance of a complete energy system consisting of an active building exterior wall heating unit, renewable energy, and an internal building terminal heating unit. The cooling and heating exterior wall panels provide active insulation and auxiliary heating and cooling. By using readily available low-grade renewable energy sources around the building, the exterior wall becomes an isolation barrier that prevents heat exchange between the interior and exterior, thereby actively shielding against the intrusion of outdoor cold through the exterior wall and the heat conduction from the exterior to the interior.

[0083] The low-grade heat source and cold source temperature used in this heating and cooling exterior wall panel can be close to the indoor set temperature. For example, a high-temperature cold source of about 26°C in summer and a low-temperature heat source of about 22°C in winter can achieve a strong active heat insulation effect.

[0084] like Figure 12 As shown in the diagram, the performance of this cooling and heating exterior wall panel under the harsh winter conditions of Harbin and the hot summer conditions of Guangzhou demonstrates that it achieves a good thermal barrier effect when the wall cooling temperature is 20-26℃ (a relatively high-temperature, low-grade cold source, compared to the traditional air conditioning supply and return temperatures of 7℃ / 12℃) in summer. This effectively insulates against outdoor heat and provides auxiliary cooling. Furthermore, by maintaining a stable radiant temperature on the indoor wall surface, it ensures the thermal comfort of the occupants. Similarly, when the wall heating temperature is 18-24℃ (a relatively high-temperature, low-grade heat source, compared to the traditional heating temperature of over 45℃) in winter, it also achieves a good thermal barrier effect, effectively insulating against indoor heat loss. Again, by maintaining a stable radiant temperature on the indoor wall surface, it ensures the thermal comfort of the occupants.

[0085] The low-grade renewable energy heat sources used in this type of wall technology can be natural solar thermal energy, waste heat recovered from data centers, or waste heat emitted from factories, etc. Low-grade renewable energy cold sources can be winter ambient cooling or relatively constant groundwater or shallow geothermal energy, etc. These readily available low-grade renewable energy sources are characterized by dispersion and seasonality, which is mismatched with building energy demand. Therefore, this energy can be collected and stored across seasons, and extracted when needed. The specific usage varies depending on the load characteristics and energy demand of different climate zones and building types. An example from a hot-summer, cold-winter climate zone is provided below. For example, to achieve efficient utilization of low-grade energy while flexibly adapting to the load characteristics of the climate zone, a cascaded utilization approach can be adopted. For instance, when building load demand is low in summer, only this wall technology is needed; while during periods of high summer load demand, the cold energy in the interseasonal cold storage is first circulated to the indoor cooling system and then to this type of system serving as the exterior wall. This efficiently eliminates indoor cooling load and forms a barrier on the exterior wall to block outdoor heat transfer, achieving the dual effects of active building insulation and energy saving, efficient use of renewable energy to meet building energy needs, and energy conservation and carbon reduction. The same principle applies in winter.Figure 13 As shown, in this usage mode, the overall energy efficiency ratio of the system can reach 8.3, and in this operating mode of the energy system, a significant environmental benefit of carbon emission reduction is generated.

[0086] As Figure 14 shown, Case 1 corresponds to the pilot scheme of the energy system supporting the exterior wall panels of this patent. The area of the single-household solar photovoltaic collector is 44 m², the cross-seasonal heat storage body is configured with 90 buried pipes with a depth of 80 m and a spacing of 2 m; the cross-seasonal cold storage body is configured with 150 buried pipes with a depth of 80 m and a spacing of 1.5 m. This case has the lowest initial investment among the four cases.

[0087] Case 2 corresponds to the pilot scheme of the energy system supporting the exterior wall panels of this patent. The area of the single-household solar photovoltaic collector is increased to 54 m², the cross-seasonal heat storage body is configured with 120 buried pipes, and the cross-seasonal cold storage body is configured with 180 buried pipes. The other parameters are the same as those in Case 1. This case achieves annual net profit.

[0088] Case 3 corresponds to the pilot scheme of the energy system supporting the exterior wall panels of this patent. The area of the single-household solar photovoltaic collector is further increased to 64 m², the cross-seasonal heat storage body is configured with 140 buried pipes with a pipe spacing of 1.8 m; the cross-seasonal cold storage body is configured with 200 buried pipes. The comprehensive benefit of this case is better than that of Case 2.

[0089] Case 4 corresponds to the pilot scheme of the energy system supporting the exterior wall panels of this patent. The area of the single-household solar photovoltaic collector is 74 m², the cross-seasonal heat storage body is configured with 149 buried pipes with a pipe spacing of 1.5 m; the cross-seasonal cold storage body is configured with 248 buried pipes. This case has the highest comprehensive benefit over the entire life cycle among the four cases.

[0090] As Figure 15 shown, when the annual comprehensive operating cost is negative, it means that this case generates income in that year. The payback periods of Case 1 and Case 4 are both shorter than the payback period of the reference system.

[0091] The overall life cycle benefits, electricity benefits, and carbon benefits of Case 4 are all higher than those of Case 1, and the overall life cycle benefit of Case 4 is higher than the overall life cycle benefit of the reference system.

[0092] The reference system is a conventional solar photovoltaic collector coupled with a ground source heat pump system, which uses a ground source heat pump to achieve heating and cooling throughout the year, and maintains the underground rock and soil heat balance through the solar heat collection system. In the comparison of Case 1, Case 2, Case 3, Case 4 and the reference system, Case 1 has the best initial investment cost and payback period, Case 4 has the best annual comprehensive operating cost and overall life cycle benefit, and the payback period of the reference system is longer than that of Case 1, Case 2, Case 3 and Case 4.

[0093] The above are merely preferred embodiments of the present invention and are illustrative in nature, not restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, all of which will fall within the protection scope of the present invention.
