Description

Technical Field

[0001] This article relates to the field of building environment control technology, specifically a wall structure and a radiant heating system. Background Technology

[0002] Traditional building heating methods mainly include radiator heating and floor radiant heating. Radiator heating occupies indoor space, and the upward convection of hot air can easily cause uneven indoor temperature and poor comfort.

Furthermore, existing heating systems have shortcomings in terms of ease of installation, integration with building interior decoration, and subsequent maintenance.

[0003] Therefore, there is an urgent need in this field for a heating solution that is easy to install, provides high thermal comfort, is energy efficient, and is easy to maintain. Summary of the Invention

[0009] In an exemplary embodiment, a heat-insulating layer is provided on the surface of the heat-spreading layer facing away from the substrate layer; Alternatively, thermal insulation material may be filled between the heating wall panel and the base wall.

[0010] In one exemplary embodiment, there are multiple heating wall panels arranged in a transverse direction, and the heat exchange tubes inside each heating wall panel are connected to the supply pipeline and the return pipeline.

[0011] In one exemplary embodiment, there are multiple heating wall panels arranged in a longitudinal and transverse manner. The heat exchange tubes inside the heating wall panels in the same longitudinal column are connected in series. The heat exchange tube inside the uppermost heating wall panel is connected to the supply pipeline, and the heat exchange tube inside the lowermost heating wall panel is connected to the return pipeline.

[0012] This application also discloses a radiant heating system, including a heat source and any of the wall structures described in the above embodiments. The heat source is connected to the supply pipeline and the return pipeline. The heat source is used to supply a heat exchange medium to the supply pipeline.

The control module is configured to stop the heat source when the temperature of the heating wall panel reaches the set target temperature value.

[0015] This application embodiment utilizes a large area of ​​the wall for low-temperature radiant heat dissipation, resulting in a more uniform indoor temperature, no draft, and higher comfort. Furthermore, compared to convection heating, radiant heating can reduce the indoor set temperature by 1 to 2°C to achieve the same thermal comfort, thus achieving energy savings.

[0016] During construction, the heating wall panels can be prefabricated in the factory.

[0024] This application discloses a wall structure.

[0025] Reference Figure 1 and Figure 2 The wall structure includes a base wall 1, on which a keel frame layer 2 and heating wall panels 3 are installed. The keel frame layer 2 is fixed to the base wall 1 by connectors, and the heating wall panels 3 are fixed to the keel frame layer 2.

[0026] In other embodiments, the heating wall panel 3 can also be directly fixed to the base wall 1 via connectors.

[0027] In this embodiment, multiple leveling keels 11 are spaced apart from top to bottom on the surface of the base wall 1. The leveling keels 11 are placed horizontally and fixed to the surface of the base wall 1 by leveling components 12. The I-beam aluminum profiles in the keel frame layer 2 are fixedly connected to the leveling keels 11 by self-tapping screws.

[0028] Specifically, the leveling keel 11 adopts a C-shaped leveling keel. The opening of the leveling keel 11 faces the wall surface of the foundation wall 1. Multiple leveling components 12 are sequentially arranged between each leveling keel 11 and the wall surface of the foundation wall 1 along the extension direction of the leveling keel 11. The leveling components 12 are fixed to the surface of the foundation wall 1. The leveling components 12 extend into the opening of the leveling keel 11 and are engaged and fixed with the leveling keel 11.

[0029] In this embodiment, the keel frame layer 2 includes multiple horizontally arranged I-beam aluminum profiles, which are vertically arranged and connected to the leveling keel 11 by self-tapping screws. Multiple heating wall panels 3 are arranged horizontally. Each heating wall panel 3 is located between two adjacent I-beam aluminum profiles in the keel frame layer 2, with the side of the heating wall panel 3 facing the I-beam aluminum profile inserting into its slot. The first and last heating wall panels 3 located at the ends of the horizontal arrangement have edge trim strips on the side facing away from the adjacent heating wall panel 3. The side of the heating wall panel 3 facing the edge trim strip is inserted into the edge trim strip, which is fixed to the leveling keel 11 by self-tapping screws.

[0030] In this embodiment, the side of the heating wall panel 3 facing the keel frame layer 2 is the back side of the heating wall panel 3, and the side of the heating wall panel 3 facing the interior of the building is the front side of the heating wall panel 3. The heating wall panel 3 includes an insulation layer 35, a heat equalization layer 33, and a substrate layer 31 arranged sequentially from the back side to the front side. The heat equalization layer 33 is bonded and fixed to the substrate layer 31 by a first adhesive layer 34. The insulation layer 35 is bonded and fixed to the surface of the heat equalization layer 33 facing away from the substrate layer 31 by a second adhesive layer 36. A groove 311 is formed on the surface of the substrate layer 31 facing the heat equalization layer 33. In this embodiment, the groove 311 is a U-shaped groove. A heat exchange tube 32 is embedded inside the groove 311, and the heat equalization layer 33 is in close contact with the heat exchange tube 32 located inside the groove 311.

[0031] In this embodiment, a decorative surface layer 312 is provided on the front side of the substrate layer 31. The decorative surface layer 312 is bonded to the substrate layer 31 by hot pressing or cold pressing to form a high-strength and aesthetically pleasing decorative surface.

[0032] In other embodiments, the heating wall panel 3 may not include an insulation layer 35, but instead fills the space between two adjacent leveling keels 11 with insulation material to achieve the purpose of heat insulation and prevent heat loss.

[0033] In this embodiment, the heat spreader 33 is made of an aluminum plate with a thickness of 0.3 mm to 0.8 mm. The aluminum plate has a thermal conductivity of up to 237 W / (m·K), resulting in high heat transfer efficiency and enabling rapid heat exchange between the heat transfer medium flowing through the heat exchange tube 32 and the aluminum plate. The thermal conductivity of building gypsum is 0.16–0.30 W / (m·K). Due to the high heat transfer efficiency of the aluminum plate, the heating rate of the heat spreader 33 is faster than that of the substrate layer 31. The heat spreader 33 rapidly transfers heat to the areas of the substrate layer 31 without grooves 311, resulting in a more uniform temperature across all areas of the substrate layer 31 and preventing heat accumulation and localized overheating.

[0034] In this embodiment, refer to Figure 3 There are multiple trenches 311, and the trenches 311 are parallel to each other. The spacing between adjacent trenches 311 is 40mm to 300mm. In adjacent trenches 311, the first end of trench 311 is connected to the second end of the upstream trench 311 through a connecting groove, and the second end of trench 311 is connected to the first end of the downstream trench 311, so that the trenches 311 on the back side of the substrate layer 31 form a serpentine channel. The ends of the trenches 311 at both ends of the arrangement direction extend to the side wall of the substrate layer 31. The heat exchange tubes 32 are laid along the formed serpentine channel, and the inlet and outlet ends of the heat exchange tubes 32 are both reserved on the outside of the substrate layer 31.

[0035] In other embodiments, refer to Figure 4 and Figure 5 The pathways formed by the trench 311 can also be designed as U-shaped pathways. The U-shaped pathways radiate outwards from the center of the substrate layer 31 in a U-shape. The U-shaped pathways formed by the trench 311 can be configured as single-loop or double-loop. When the U-shaped pathway formed by the trench 311 is a double-loop, the two U-shaped pathways are arranged along the width direction of the substrate layer 31. When the U-shaped pathway formed by the trench 311 is a double-loop, there are two heat exchange tubes 32, with both the inlet and outlet ends of the heat exchange tubes 32 pre-existing outside the substrate layer 31.

[0036] In this embodiment, the interior of the heat exchange tube 32 is used for the flow of the heat exchange medium. When the heat exchange medium flows through the interior of the heat exchange tube 32, the heat of the heat exchange medium in the heat exchange tube 32 exchanges heat with the substrate layer 31 and the heat spreader layer 33, causing the temperature of the substrate layer 31 and the heat spreader layer 33 to rise or fall. In this embodiment, the substrate layer 31 is made of gypsum board, and the heat spreader layer 33 is made of aluminum plate. The heat exchange efficiency of the substrate layer 31 is lower than that of the heat spreader layer 33. Therefore, the temperature change rate of the heat spreader layer 33 is faster than that of the substrate layer 31, so that heat exchange also occurs between the substrate layer 31 and the heat spreader layer 33, making the temperature of each area of ​​the substrate layer 31 more uniform and avoiding heat accumulation that could lead to local overheating or overcooling.

[0037] In this embodiment, the heat exchange tube 32 is made of PE-XA cross-linked polyethylene pipe, which is embedded inside the passage formed between the grooves 311. The laying path of the heat exchange tube 32 is set along the path of the passage formed by the grooves 311. The PE-XA cross-linked polyethylene pipe has high flexibility and can be bent in the connecting groove between two adjacent grooves 311. At the same time, the PE-XA cross-linked polyethylene pipe has the characteristics of high temperature and high pressure resistance, and its high temperature resistance can reach 95°C and its burst pressure can reach 6MPa.

[0038] In this embodiment, the insulation layer 25 has a thickness of 10mm to 20mm and a density of not less than 30kg / m³. 3 The insulation layer 35 is made of extruded polystyrene (XPS) insulation board. XPS insulation board has a B1 fire rating, classifying it as a flame-retardant material that extinguishes immediately upon removal of the flame source, effectively preventing the spread of fire. It should be noted that the insulation layer 35 is not limited to XPS insulation board; other insulation materials with a fire rating of at least B1 and superior insulation performance can also be used as the insulation layer 25. In this embodiment, the substrate layer 31 provides a decorative surface and heat storage function, while the heat equalization layer 33 ensures uniform temperature distribution. The insulation layer 35 effectively prevents heat loss, significantly improving thermal efficiency.

[0039] In this embodiment, refer to Figure 2 The wall structure also includes a supply and return assembly 4, which is installed at the top or bottom of the heating wall panel 3. The supply and return assembly 4 includes a supply pipe 41 and a return pipe 42. The supply pipe 41 is connected to the inlet end of the heat exchange tube 32 inside the heating wall panel 3. The return pipe 42 is connected to the return end of the heat exchange tube 32 inside the heating wall panel 3.

[0040] In this embodiment, a top line 5 is provided on the top front of the heating wall panel 3, and the top line 5 is fixedly connected to the heating wall panel 3 or the foundation wall 1. A first chamber 51 is provided inside the top line 5, which extends along the direction of the top line 5. The first chamber 51 is used to install the supply pipe 41 and the return pipe 42.

[0041] In this embodiment, a skirting board 6 is provided on the bottom front of the heating wall panel 3, and the skirting board 6 is fixedly connected to the heating wall panel 3 or the foundation wall 1. A second chamber 61 is provided inside the skirting board 6 along the extending direction of the skirting board 6, and the second chamber 61 is used to install the supply pipe 41 and the return pipe 42.

[0042] In actual installation, when both the inlet and outlet of the heat exchanger 32 are located at the top of the heating wall panel 3, the supply pipe 41 and return pipe 42 are installed in the first chamber 51 of the top rail 5. When both the inlet and outlet of the heat exchanger 32 are located at the bottom of the heating wall panel 3, the supply pipe 41 and return pipe 42 are installed in the second chamber 61 of the skirting board 6. When the inlet of the heat exchanger 32 is located at the top of the heating wall panel 3 and the outlet of the heat exchanger 32 is located at the bottom of the heating wall panel 3, the supply pipe 41 is installed in the first chamber 51 of the top rail 5, and the return pipe 42 is installed in the second chamber 61 of the skirting board 6. When the inlet end of the heat exchange tube 32 is located at the bottom of the heating wall panel 3 and the return end of the heat exchange tube 32 is located at the top of the heating wall panel 3, the supply pipe 41 is installed in the second chamber 61 of the skirting board 6 and the return pipe 42 is installed in the first chamber 51 of the top line 5.

[0043] In other embodiments, a top rail 5 may be provided only at the top of the heating wall panel 3, or a skirting board 6 may be provided only at the bottom of the heating wall panel 4. If the top rail 5 is provided only at the top of the heating wall panel 3, both the supply pipe 41 and the return pipe 42 are located in the first chamber 51 of the top rail 5. If the skirting board 6 is provided only at the bottom of the heating wall panel 3, both the supply pipe 41 and the return pipe 42 are located in the second chamber 51 of the skirting board 6.

[0044] In this embodiment, the inlet end of the heat exchange tube 32 inside each heating wall panel 3 is connected to the supply pipe 41, and the return end of the heat exchange tube 32 is connected to the return pipe, so that all the heat exchange tubes 32 inside the heating wall panels 3 are connected in parallel and are independent of each other. Valves are installed between the inlet end of the heat exchange tube 32 and the supply pipe 41, and between the return end of the heat exchange tube 32 and the return pipe 42, to control the opening and closing of the heat exchange tube 32 with the supply pipe 41 and the return pipe 42. When a heating wall panel 3 malfunctions, the corresponding valve is closed, and the heating wall panel 3 can be disassembled individually for repair or replacement without affecting the normal operation of other heating wall panels 3, making maintenance more convenient.

[0045] In other embodiments, the number of supply pipes 41 and return pipes 42 can also be set to multiple. The number of supply pipes 41 and return pipes 42 is the same as the number of heating wall panels 3 and corresponds one-to-one. The supply pipe 41 is connected to the inlet end of the heat exchange pipe 32 of the corresponding heating wall panel 3, and the return pipe 42 is connected to the return end of the heat exchange pipe 32 of the corresponding heating wall panel 3.

[0046] In other embodiments, multiple heating wall panels 3 are arranged in a transverse direction. The inlet end of the heat exchange tube 32 inside the heating wall panel 3 is connected to the return end of the heat exchange tube 32 inside the upstream heating wall panel 3, and the return end of the heat exchange tube 32 is connected to the inlet end of the heat exchange tube inside the downstream heating wall panel 3, so that all the heat exchange tubes 32 inside the heating wall panel 3 are connected in series. The inlet end of the heat exchange tube 32 inside the upstream heating wall panel 3 is connected to the supply pipe 41, and the return end of the heat exchange tube 32 inside the downstream heating wall panel 3 is connected to the return pipe 42.

[0047] In other embodiments, there are multiple heating wall panels 3 arranged in both longitudinal and transverse directions. The top line 5 is located at the top of the uppermost heating wall panel 3, and the skirting board 6 is located at the bottom of the lowermost heating wall panel 3. In the heating wall panels 3 arranged in the same longitudinal column, the inlet end of the heat exchange tube 32 inside the heating wall panel 3 is connected to the return end of the heat exchange tube 32 inside the uppermost heating wall panel 3, and the return end of the heat exchange tube 32 is connected to the inlet end of the heat exchange tube 32 inside the lowermost heating wall panel 3, thus forming a series connection between the heat exchange tubes 32 arranged longitudinally. The inlet end of the heat exchange tube 32 inside the uppermost heating wall panel 3 is connected to the supply pipe 41, and the return end of the heat exchange tube 32 inside the lowermost heating wall panel 3 is connected to the return pipe 42.

[0048] This application also discloses a radiant heating system.

[0049] Reference Figure 6 The radiant heating system includes a heat source 7, a thermostat 8, and the wall structure disclosed in the embodiments of this application. The heat source 7 is connected to a supply pipe 41 and a return pipe 42. The heat source 7 is used to supply heat exchange medium into the supply pipe 41. After entering the supply pipe 41, the heat exchange medium flows along the supply pipe 41 into the heat exchange tube 32 inside the heating wall panel 3. When the heat exchange medium flows through the heat exchange tube 32, it exchanges heat with the heating wall panel 3, causing the temperature of the heating wall panel 3 to rise. After flowing through the heat exchange tube 32, the heat exchange medium flows through the return end of the heat exchange tube 32 into the return pipe 42. Finally, the heat exchange medium flows back to the heat source 7 along the return pipe 42, where the heat source 7 heats the returning heat exchange medium, causing its temperature to rise again, and it enters the next cycle.

[0050] In this embodiment, the heat source 7 is a wall-mounted boiler or an air source heat pump.

[0051] In this embodiment, the thermostat 8 is electrically connected to the heat source 7. The thermostat 8 is used to obtain the ambient temperature inside the building, set the target temperature, and send control signals to the heat source 7 to control the heat source 7.

[0052] The thermostat 8 includes a control module 81 and a first temperature acquisition element 82. The control module 81 is electrically connected to the heat source 7 and sends control commands to the heat source 7. The heat source 7 responds to the control commands issued by the control module 81 and performs corresponding actions. The first temperature acquisition element 82 is electrically connected to the control module 81. The first temperature acquisition element 82 is a temperature sensor. The first temperature acquisition element 82 is installed inside the building and is used to acquire the temperature value of the building's interior environment in real time and transmit the acquired temperature value to the control module 81.

[0053] When the radiant heating system is in use, a target temperature value is first preset for the control module 81. The first temperature acquisition element 82 transmits the acquired temperature value to the control module 81. The control module 81 compares the temperature value acquired by the first temperature acquisition element 82 with the target temperature value. When the temperature value acquired by the first temperature acquisition element 82 is lower than the target temperature value, the control module 81 sends a start signal to the heat source 7. The heat source 7 responds to the start signal from the control module 81 and begins combustion, sending the heat medium into the supply pipe 41. When the ambient temperature value acquired by the first temperature acquisition element 82 reaches the target temperature value, the control module 81 sends a stop signal to the heat source 7, and the heat source 7 responds to the stop signal from the control module 81 and stops heating.

[0054] In this embodiment, the thermostat 8 further includes a second temperature acquisition element 83, which is a temperature sensor. The second temperature acquisition element 83 is electrically connected to the control module 81. The second temperature acquisition element 83 is disposed on the back of the heating wall panel 3 and is used to acquire the temperature of the heating wall panel in real time and transmit the acquired temperature value to the control module 81. The control module 81 compares the temperature value acquired by the second temperature acquisition element 83 with the target temperature value. When the temperature value acquired by the second temperature acquisition element 83 reaches the target temperature value, the control module 81 sends a stop signal to the heat source 7. The heat source 7 responds to the stop signal sent by the control module 81 and stops heating to prevent the heating wall panel 3 from overheating.

[0055] In this embodiment, when one of the temperature values ​​acquired by the first temperature acquisition element 82 and the second temperature acquisition element 83 reaches the target temperature value, the control unit sends a stop signal to the heat source 7 to control the heat source 7 to stop heating.
