Description

Technical Field

[0001] The present application relates to the technical field of building thermal insulation and energy saving, and in particular to an exterior wall thermal insulation system and a control method thereof. Background Art

[0002] The exterior wall insulation system refers to an engineering practice that uses a certain fixing method (bonding, mechanical anchoring, pasting + mechanical anchoring, spraying, pouring, etc.) to fix the insulating material with a low thermal conductivity coefficient to the wall of the building, thereby increasing the average thermal resistance of the wall and achieving the effect of thermal insulation or heat insulation.

[0003] A prefabricated exterior wall insulation system is disclosed in a Chinese patent document with announcement number CN217812057U, and specifically discloses an insulation board assembly, at least one group of wall-mounted assemblies and an exterior wall transverse keel, wherein the exterior wall transverse keel is fixedly connected to the wall; the insulation board assembly includes a panel, at least two panel vertical keels, at least one panel transverse keel and at least two keel connectors, wherein each panel vertical keel is fixedly connected to the panel by a connecting nail; each group of wall-mounted assemblies includes a sub-connector and a mother connector; the insulation board assembly and the exterior wall are interlocked with each other through the sub-connector and the mother connector to achieve rapid installation, thereby simplifying the on-site procedures and the installation process, and allowing the insulation board assembly and the panel to be replaced separately; the insulation board assembly is adjusted in three dimensions in the longitudinal, transverse and vertical directions by the wall-mounted assembly, thereby ensuring the installation accuracy of the insulation board assembly; by using connecting nails to penetrate from the front of the panel to the back of the panel and fix the panel to the panel vertical keels, the problems that may be caused by using back bolts are avoided.

[0004] However, in the above-mentioned patent, the insulation effect of the exterior wall is only achieved by relying on the thermal insulation properties of the insulation board assembly itself, and the overall insulation effect is still in a poor state. In addition, there are high requirements for the installation flatness of the insulation board assembly, which increases the difficulty of installation. Summary of the invention

[0005] In order to overcome the deficiencies of the prior art, the present application provides an exterior wall insulation system and a control method thereof.

[0006] The present application is implemented using the following technical solution: an exterior wall insulation system, which is arranged on the surface of a wall, comprises a frame assembly and a plurality of insulation cover plates fixed on the frame assembly, a heat-conducting assembly is provided on the inner side of the insulation cover plate, the heat-conducting assembly is in contact with the surface of the wall, a flowing heat-conducting medium is provided in the heat-conducting assembly, and the heat-conducting medium is used to transfer heat to the surface of the wall or absorb heat from the surface of the wall.

[0007] By adopting the above technical solution, the thermal insulation cover plate plays a preliminary role in heat insulation and heat preservation of the wall. When the external temperature is low in winter or other environments, a heat-conducting medium with a higher temperature can be transported into the heat-conducting component, thereby transporting the heat in the heat-conducting medium to the surface of the wall, reducing the heat loss on the surface of the wall, and playing a role in heat preservation of auxiliary heating. When the external temperature is high in summer or other environments, a heat-conducting medium with a lower temperature can be transported into the heat-conducting component, thereby absorbing the heat on the surface of the wall into the heat-conducting medium, reducing the significant increase in the surface temperature of the wall caused by solar radiation, playing a role in heat preservation of auxiliary cooling, and effectively improving the heat preservation effect of the building wall.

[0008] Optionally, the frame assembly includes a frame body and a fixed base, the fixed base is detachably arranged on the surface of the wall, the frame body is fixed by at least four fixed bases, and an ear plate is provided on the side wall of the thermal insulation cover plate, and the ear plate is fixed to the frame assembly by bolts.

[0009] By adopting the above technical solution, the fixed base plays a role in fixing the frame body. In this way, when the frame body is securely fixed by the fixed base, the thermal insulation cover plate can be placed on the frame body, and then the ear plate and the frame body can be locked by bolts, so that the thermal insulation cover plate can be reliably and quickly installed.

[0010] Optionally, the thermal insulation cover plate is in a square cover shape, and there is a gap between two adjacent thermal insulation cover plates. The heat conduction component is arranged on the inner side of the thermal insulation cover plate and is separated from the thermal insulation cover plate.

[0011] By adopting the above technical solution, it is ensured that there is enough space between the insulation cover and the wall for the installation of the heat-conducting component. At the same time, after the insulation cover is installed, sealant can be used to fill the gap, so that a relatively closed space can be formed between several insulation cover plates and the wall, further improving the insulation effect of the wall.

[0012] Optionally, a first water collecting pipe is provided at the upper part of the frame assembly, a second water collecting pipe is provided at the lower part of the frame assembly, a plurality of heat conducting component modules are provided between the first water collecting pipe and the second water collecting pipe, and the heat conducting component modules are composed of a plurality of heat conducting components in the same row;

[0013] The upper end of the heat-conducting component module is connected to the first water collecting pipe through a first branch pipe, and the lower end of the heat-conducting component module is connected to the second water collecting pipe through a second branch pipe.

[0014] By adopting the above technical solution, under the connection of the first branch pipe and the second branch pipe, the heat-conducting medium in the first collecting pipe can flow into the heat-conducting component module evenly and flow back to the second collecting pipe in a concentrated manner. At the same time, the heat-conducting medium in the second collecting pipe can also flow back into the heat-conducting component module, thereby realizing the reliable and circulating flow of the heat-conducting medium in the heat-conducting component module and improving the thermal insulation effect of the wall.

[0015] Optionally, the first water collecting pipe is provided with a first water inlet pipe and a first water outlet pipe, and the second water collecting pipe is provided with a second water inlet pipe and a second water outlet pipe;

[0016] The first water inlet pipe is provided with a first water inlet valve, and the second water inlet pipe is provided with a second water inlet valve;

[0017] The first water outlet pipe is provided with a first water outlet valve, and the second water outlet pipe is provided with a second water outlet valve;

[0018] A first water tank is provided above the wall, and a second water tank is provided below the wall. The first water inlet pipe and the second water outlet pipe are both connected to the first water tank, and the second water inlet pipe and the first water outlet pipe are both connected to the second water tank.

[0019] By adopting the above technical solution, the first water storage tank is used to store the heat-conducting medium with a higher temperature, and the second water storage tank is used to store the heat-conducting medium with a lower temperature. By controlling the opening and closing states of the first water inlet valve, the first water outlet valve, the second water inlet valve and the second water outlet valve, the heat-conducting medium circulates between the first water storage tank and the heat-conducting component or circulates between the second water storage tank and the heat-conducting component, thereby achieving effective insulation of the wall in environments with different temperatures.

[0020] Optionally, the first water inlet valve and the second water outlet valve are in the same opening and closing state, the second water inlet valve and the first water outlet valve are in the same opening and closing state, and the first water inlet valve and the second water inlet valve are in opposite opening and closing states.

[0021] By adopting the above technical solution, the temperature of the heat-conducting medium flowing in the heat-conducting component can be reliably controlled by controlling and adjusting the opening and closing of the first water inlet valve and the second water outlet valve and the opening and closing of the second water inlet valve and the first water outlet valve, thereby further improving the thermal insulation effect of the wall.

[0022] Optionally, the first water storage tank may be disposed on the roof of a building and used to store a heat-conducting medium for transferring heat to the surface of a wall, and the second water storage tank may be disposed below the ground and used to store a heat-conducting medium for absorbing heat from the surface of a wall.

[0023] By adopting the above technical solution, the first water storage tank is arranged on the roof of the building, so that the heat-conducting medium in the first water storage tank can be heated by solar energy. The second water storage tank is arranged below the ground, and the heat-conducting medium in the second water storage tank can be naturally cooled. In this way, the temperature of the heat-conducting medium can be controlled without consuming energy, thereby reliably insulating the wall.

[0024] Optionally, the heat conduction component includes two transverse tubes and a plurality of vertical tubes, the ends of the two transverse tubes are both in a sealed state, the plurality of vertical tubes are arranged between the two transverse tubes at intervals, and the two ends of the vertical tubes are respectively and one-to-one connected to the two transverse tubes;

[0025] The first branch pipe is connected to the top of the uppermost transverse pipe, and the second branch pipe is connected to the bottom of the lowermost transverse pipe;

[0026] The two transverse tubes of two adjacent heat-conducting components are connected via a butt-joint tube;

[0027] A plurality of through holes are arranged on the side wall of the vertical pipe, and sealing plugs are adaptively arranged in the through holes. An elastic ring is sleeved on the outer wall of the sealing plug, and the elastic ring is interference-fitted with the through holes.

[0028] By adopting the above technical scheme, under the docking action of the docking pipe, the two adjacent heat-conducting components in the vertical direction can be reliably connected. Under the connecting action of the first branch pipe, the heat-conducting component located at the top will be connected to the first water collecting pipe, and under the connecting action of the second branch pipe, the heat-conducting component located at the bottom will be connected to the second water collecting pipe. In this way, the several heat-conducting components in each heat-conducting component module are in a state of interconnection, so that the heat-conducting medium can circulate in the first water collecting pipe, the heat-conducting component module and the second water collecting pipe, and the first water collecting pipe and the second water collecting pipe play a role in draining and guiding the heat-conducting medium, ensuring that there is enough heat-conducting medium flowing in each heat-conducting component module, thereby ensuring reliable insulation effect on the wall.

[0029] Optionally, one end of the butt joint pipe is in communication with the transverse pipe, the other end of the butt joint pipe is provided with a sleeve, a butt joint is provided in the sleeve, one end of the butt joint is connected to the inner wall of the sleeve and there is a distance between the butt joint and the butt joint pipe;

[0030] The other end of the butt joint is in an arc shape, and the other end of one butt joint and the other end of another adjacent butt joint are pressed against each other;

[0031] A docking channel is arranged in the docking joint, and the docking channel penetrates the docking joint in the axial direction. A plurality of steel rings are arranged on the inner side of the docking joint, and the steel rings are used to support the docking channel to be in a smooth state.

[0032] By adopting the above technical solution, when the insulation cover is installed, the two butt joints in the two heat-conducting components will be in a state of butt jointing with each other. Specifically, there is a gap between the two adjacent insulation cover plates, and there will be extrusion between the two butt joints, so that the two butt joints can be reliably butt jointed, and then the two adjacent heat-conducting components can be in a state of interconnection. Under the limiting effect of the steel ring, the butt joints will not be blocked during the mutual extrusion process, ensuring that the heat-conducting medium can flow between the heat-conducting components through the butt joints and the butt joints.

[0033] The control method of the external wall thermal insulation system is applied to the external wall thermal insulation system and comprises the following steps:

[0034] S1. When the outdoor temperature is lower than a preset value, the first water inlet valve and the second water outlet valve are opened, and the first water outlet valve and the second water inlet valve are closed, so that the heat transfer medium in the first water storage tank circulates between the heat transfer component and the first water storage tank, thereby transferring the heat in the heat transfer medium to the surface of the wall to achieve auxiliary heating;

[0035] S2. When the outdoor temperature is higher than a preset value, the second water inlet valve and the first water outlet valve are opened, and the second water outlet valve and the first water inlet valve are closed, so that the heat transfer medium in the second water storage tank circulates between the heat transfer component and the second water storage tank, thereby transferring the heat on the surface of the wall to the heat transfer medium to achieve auxiliary cooling.

[0036] By adopting the above technical solution, the walls can be effectively insulated in environments with different temperatures, ensuring that the temperature inside the building is maintained at a relatively constant state.

[0037] Compared with the prior art, this application has the following beneficial effects:

[0038] 1. While installing the insulation cover on the frame body, the heat conduction component is docked, and then the heat is transported to the wall or the heat in the wall is absorbed by transporting the heat conduction medium in the heat conduction component, so as to heat or cool the wall at different temperatures, thereby realizing reliable active insulation of the wall.

[0039] 2. By controlling the opening and closing states of the first water inlet valve, the first water outlet valve, the second water inlet valve and the second water outlet valve, the heat-conducting medium with a higher temperature in the first water storage tank can be selectively input into the heat-conducting component, or the heat-conducting medium with a lower temperature in the second water storage tank can be input into the heat-conducting component, so that heat-conducting media with different temperatures are selected to circulate in the heat-conducting component according to different ambient temperatures, thereby maximizing the thermal insulation effect on the wall.

[0052] Below, combined with the attached Figure 1-5 As well as specific implementation methods, the present application is further described. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0053] This embodiment discloses an exterior wall insulation system.

[0054] Figure 1 is a schematic three-dimensional diagram of the present application. Figure 1 The exterior wall insulation system is arranged on the surface of the wall 1 to keep the wall 1 warm, so that the temperature inside the building is kept at a relatively constant state, reducing the energy loss caused by the use of air conditioners and other equipment to control the temperature in the building.

[0055] Figure 2This is a reference diagram of the assembly status of the frame assembly and the heat conduction assembly. Figure 2 The exterior wall insulation system includes a frame assembly 2, an insulation cover plate 3 and a heat-conducting assembly 4. The frame assembly 2 includes a frame body 21 and a fixed base 22. The fixed base 22 is detachably arranged on the surface of the wall 1. The frame body 21 is fixed by at least four fixed bases 22. The frame body 21 is in a grid shape. Ear plates 31 are arranged on the side walls of the insulation cover plate 3. The ear plates 31 are fixed to the frame assembly 2 by bolts 32. In this way, each insulation cover plate 3 can be reliably fixed to the frame body 21. At the same time, after the insulation cover 3 is fixed, there will be a gap between two adjacent insulation cover boards 3, which can be filled with sealant to improve the aesthetics. Furthermore, the insulation cover board 3 is in a square cover shape, ensuring that there is enough space between the insulation cover board 3 and the surface of the wall 1 for placing the heat-conducting component 4. When the gap is filled with sealant, the space is in a relatively closed state, which can prevent external air from flowing in the space and causing excessive heat loss to a certain extent, thereby improving the insulation effect of the insulation cover board 3 on the foundation of the wall 1.

[0056] Figure 3 is a schematic three-dimensional diagram of a heat conducting component. Figure 3 Combined with Figure 2The heat-conducting assembly 4 includes two transverse tubes 45 and a plurality of vertical tubes 46. The ends of the two transverse tubes 45 are sealed. The plurality of vertical tubes 46 are arranged between the two transverse tubes 45 at intervals. The two ends of the vertical tubes 46 are connected to the two transverse tubes 45 respectively and one by one. A heat-conducting assembly 4 is correspondingly arranged on the inner side of each heat-insulating cover plate 3. Moreover, the heat-conducting assembly 4 and the heat-insulating cover plate 3 are in a state of being separated from each other and in a state of being in contact with the wall 1. Furthermore, the transverse tubes 45 and the vertical tubes 46 are both square tubes. In this way, the transverse tubes 45 and the vertical tubes 46 can contact the wall 1 with a larger area. A first water collecting pipe 41 is arranged at the upper end of the frame body 21, and a second water collecting pipe 42 is arranged at the lower end. The first water collecting pipe 41 and the second water collecting pipe 42 both extend along the width direction of the frame body 21. A plurality of first branch pipes 411 are arranged at the bottom of the first water collecting pipe 41, and a plurality of second branch pipes 421 are arranged at the top of the second water collecting pipe 42. The plurality of heat-conducting components 4 are arranged in a grid shape, and all the heat-conducting components 4 in the same row can form a heat-conducting component 4 module, and the plurality of heat-conducting component 4 modules also extend along the width direction of the frame body 21. In a heat-conducting component 4 module, the heat-conducting component 4 located at the top is connected to the first branch pipe 411 (specifically, the cross pipe 45 located at the top of the heat-conducting component 4 is connected to the first branch pipe 411), the heat-conducting component 4 located at the bottom is connected to the second branch pipe 421 (specifically, the cross pipe 45 located at the bottom of the heat-conducting component 4 is connected to the second branch pipe 421), and the other heat-conducting components 4 located in the middle are connected through the butt joint 47 (specifically, each of the cross pipes 45 of these heat-conducting components 4 is provided with a butt joint 47). In this way, under the connecting action of the first branch pipe 411, the butt joint 47 and the second branch pipe 421, the first water collecting pipe 41, each heat-conducting component 4 in the heat-conducting component 4 module and the second water collecting pipe 42 are in a state of being connected to each other.

[0057] See also Figure 1 and Figure 2A first water inlet pipe 412 and a first water outlet pipe 413 are provided on the first water collecting pipe 41, a second water inlet pipe 422 and a second water outlet pipe 423 are provided on the second water collecting pipe 42, a first water inlet valve 4120 is provided on the first water inlet pipe 412, a second water inlet valve 4220 is provided on the second water inlet pipe 422, a first water outlet valve 4130 is provided on the first water outlet pipe 413, and a second water outlet valve 4230 is provided on the second water outlet pipe 423. A first water storage tank 43 is provided above the wall 1, and a second water storage tank 44 is provided below the wall 1. The first water inlet pipe 412 and the second water outlet pipe 423 are both connected to the first water storage tank 43, and the second water inlet pipe 422 and the first water outlet pipe 413 are both connected to the second water storage tank 44. Both the first water tank 43 and the second water tank 44 can store heat-conducting media. Moreover, the first water tank 43 can be set on the top of the building, so that the heat-conducting medium in the first water tank 43 can be heated by solar energy, so that the heat-conducting medium in the first water tank 43 is in a state of higher temperature. The second water tank 44 can be set below the ground, so that the heat-conducting medium in the second water tank 44 can be in a state of lower temperature by utilizing the lower underground temperature.

[0058] The first water inlet valve 4120 and the second water outlet valve 4230 are in the same opening and closing state, the second water inlet valve 4220 and the first water outlet valve 4130 are in the same opening and closing state, and the first water inlet valve 4120 and the second water inlet valve 4220 are in opposite opening and closing states. In this way, when the first water inlet valve 4120 and the second water outlet valve 4230 are in the open state and the second water inlet valve 4220 and the first water outlet valve 4130 are in the closed state, the higher temperature heat transfer medium in the first water storage tank 43 will flow in sequence. The heat conduction medium passes through the first water inlet pipe 412, the first water collecting pipe 41 and the heat conduction component 4 and enters the second water collecting pipe 42, and finally flows back to the first water storage tank 43 through the second water outlet pipe 423, while the heat conduction medium in the second water storage tank 44 will stay in the second water storage tank 44. Since the heat conduction component 4 and the wall 1 are in a state of mutual contact, when the heat conduction medium with a higher temperature flows in the heat conduction component 4, the heat in the heat conduction component 4 will be transported to the surface of the wall 1, thereby heating the wall 1. When the second water inlet valve 4220 and the first water outlet valve 4130 are in the open state and the first water inlet valve 4120 and the second water outlet valve 4230 are in the closed state, the heat-conducting medium with a lower temperature in the second water storage tank 44 will pass through the second water inlet pipe 422, the second water collecting pipe 42 and the heat-conducting component 4 in sequence and enter the first water collecting pipe 41, and finally flow back to the second water storage tank 44 through the first water outlet pipe 413, while the heat-conducting medium in the first water storage tank 43 will stay in the first water storage tank 43. In this way, when the heat-conducting medium with a lower temperature flows in the heat-conducting component 4, the heat-conducting component 4 will absorb the surface of the wall 1. The heat of the wall 1 is used to cool the wall 1. That is to say, when it is in a low temperature environment such as winter, a heat-conducting medium with a higher temperature is selected to flow in the heat-conducting component 4, and when it is in a high temperature environment such as summer, a heat-conducting medium with a lower temperature is selected to flow in the heat-conducting component 4. In this way, the temperature difference between the wall 1 and the temperature inside the building can be kept at a relatively constant state without consuming too much extra energy, thereby playing a reliable insulation role for the wall 1, and the control accuracy of the insulation effect can be improved by adjusting the temperature and flow rate of the heat-conducting medium, thereby significantly improving the insulation effect.

[0059] Figure 4 This is a cross-sectional view of the internal structure of the butt joint. Figure 4 Combined with Figure 2One end of the butt joint 47 is connected to the cross pipe 45, and the other end of the butt joint 47 is provided with a sleeve 471, and a butt joint 472 is provided in the sleeve 471, and one end of the butt joint 472 is connected to the inner wall of the sleeve 471 and there is a distance between the butt joint 47 and the butt joint 472, and the other end of the butt joint 472 is in an arc shape, and the other end of one butt joint 472 and the other end of another adjacent butt joint 472 are squeezed against each other, and a butt joint 472 is provided in the butt joint 472, and the butt joint 472 passes through the butt joint 472 along the axial direction, and a plurality of steel rings 4722 are provided on the inner side of the butt joint 472, and the steel rings 4722 are used to support the butt joint 4721 to be in a smooth state. The transverse tube 45 of the heat-conducting component 4 can be clamped on the inner side of the heat-insulating cover plate 3 to fix the heat-conducting component 4, or the heat-conducting component 4 can be directly fixed on the surface of the wall 1 by means of a clamp or other structure. In this way, during the installation of the heat-insulating cover plate 3 or the heat-conducting component 4, the two butt joints 47 of two adjacent heat-conducting components 4 in the same heat-conducting component 4 module will be close to each other, and a certain amount of extrusion will occur between the corresponding two butt joints 472, thereby ensuring that the corresponding two butt joints 4721 can be in a reliably sealed state, and thus ensuring that the two adjacent heat-conducting components 4 can be reliably butted and connected through the butt joints 47. During the extrusion of the two butt joints 472, the butt joint 4721 will be deformed to a certain extent, and under the action of the steel ring 4722, the butt joint 4721 can remain unobstructed, ensuring that the heat-conducting medium can reliably flow through the butt joint 4721 after the butt joint is completed.

[0060] Figure 5 This is a reference diagram of the explosion state of the vertical pipe. Figure 5 Combined with Figure 2 Furthermore, a plurality of perforations 461 are provided on the side wall of the vertical pipe 46, and a sealing plug 462 is adapted to be provided in the perforation 461, and an elastic ring 4620 is sleeved on the outer wall of the sealing plug 462, and the elastic ring 4620 and the perforation 461 are interference fit. During the normal flow of the heat-conducting medium, the sealing plug 462 can reliably seal the perforation 461 to ensure reliable insulation of the wall 1. When a fire occurs inside the building, the first water inlet valve 4120 and the second water inlet valve 4220 can be opened at the same time, and the first water outlet valve 4130 and the second water outlet valve 4230 can be closed. In this way, the heat-conducting medium in the first water storage tank 43 and the second water storage tank 44 will flow toward the heat-conducting component 4. When the pressure of the heat-conducting medium in the heat-conducting component 4 reaches a threshold, the sealing plug 462 will be pushed out from the perforation 461. At this time, the heat-conducting medium will flow out of the heat-conducting component 4 and fall onto the surface of the wall 1, which can also play a certain role in cooling and extinguishing the fire. At the same time, a through hole 33 can be opened below the front side of the thermal insulation cover plate 3. When the heat-conducting medium flows out, it can pass through the through hole 33 and flow on the surface of the thermal insulation cover plate 3, which can play a warning role and expand the functionality of the thermal insulation system.

[0061] This embodiment also discloses a control method for an exterior wall insulation system.

[0062] The control method of the external wall thermal insulation system is applied to the external wall thermal insulation system and comprises the following steps:

[0063] S1. When the outdoor temperature is lower than a preset value, the first water inlet valve 4120 and the second water outlet valve 4230 are opened, and the first water outlet valve 4130 and the second water inlet valve 4220 are closed, so that the heat-conducting medium in the first water storage tank 43 circulates between the heat-conducting component 4 and the first water storage tank 43, thereby transferring the heat in the heat-conducting medium to the surface of the wall 1, thereby achieving auxiliary heating;

[0064] S2. When the outdoor temperature is higher than a preset value, the second water inlet valve 4220 and the first water outlet valve 4130 are opened, and the second water outlet valve 4230 and the first water inlet valve 4120 are closed, so that the heat-conducting medium in the second water storage tank 44 circulates between the heat-conducting component 4 and the second water storage tank 44, thereby transferring the heat on the surface of the wall 1 to the heat-conducting medium to achieve auxiliary cooling.

[0065] By controlling the opening and closing states of the first water inlet valve 4120 , the first water outlet valve 4130 , the second water inlet valve 4220 and the second water outlet valve 4230 , heat transfer media of different temperatures can be selected to flow in the heat transfer component 4 , thereby improving the heat preservation effect of the heat preservation system on the surface of the wall 1 .

[0066] The above-mentioned implementation modes are only preferred implementation modes of the present application and cannot be used to limit the scope of protection of the present application. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present application shall fall within the scope of protection required by the present application.
