Description

Technical Field

[0001] The present invention relates to the technical field of ventilation and thermal insulation floor slabs, and in particular to a ventilation and thermal insulation module heating and cooling floor. Background Art

[0002] With global warming, energy conservation and emission reduction have become a global consensus. Ventilated and insulated modular floor heating and cooling, as a highly efficient heating and cooling method, can reduce energy consumption and carbon emissions, meeting the needs of energy conservation and emission reduction. Ventilated and insulated modular floor heating and cooling achieves uniform indoor temperature distribution, enhancing living comfort. Furthermore, it facilitates ventilation, keeping indoor air fresh, further improving living quality.

[0003] After searching, it was found that most of the existing technologies have some defects in actual use. First, during the operation of the floor heating pipes, due to the temperature fluctuation of the fluid, thermal expansion and contraction will occur. The thermal expansion and contraction phenomenon will not only cause slight deformation of the pipes themselves, but also cause fatigue of the pipe materials. This fatigue will gradually accumulate, and eventually lead to a decrease in pipe strength and an increased risk of leakage; second, since floor heating pipes are usually laid below the ground, once a problem occurs, it is often difficult to observe directly, so it is difficult to judge the status of the pipes, and there is a risk of aging and leakage in the pipes. The fluid in the floor heating pipes is usually hot water or other heat carriers. If a leak occurs, it will not only affect the heating effect, but may also cause safety hazards, especially in homes or public buildings. Once the floor heating pipes leak, it may cause serious consequences such as fire and electric shock.

[0021] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0022] Example 1, refer to Figure 1-Figure 5, a ventilation and insulation module heating and cooling floor, including a building body 1, an external control system and a combined floor paved at the bottom of the building body 1, the combined floor is composed of an insulation layer, a prefabricated floor heating groove module 2, a circulation pipe 4, a covering layer 27, a decorative surface layer 26 and a ventilation system 11 above the decorative surface layer 26 from bottom to top, the prefabricated floor heating groove module 2 is composed of a left-path card plate 21, an outer ring card plate 23, a right-path card plate 22, a connecting card plate 24 and an inner ring card plate 25. This modular design facilitates construction and installation, improves work efficiency, and is also convenient for later maintenance and replacement. A number of grooves are provided on the prefabricated floor heating groove module 2, and the grooves serve as channels and air ducts for laying the circulation pipe 4. The surface and grooves of the prefabricated floor heating groove module 2 are coated with a thermal conductive waterproof coating, which can significantly improve the thermal conductivity of the module, so that heat or cold can be transferred to the ground faster, thereby improving heating and cooling. The effect is great. At the same time, it can prevent moisture from penetrating into the module, avoid damaging the insulation layer, and extend the service life of the entire system. The grooves are composed of horizontal grooves 50, arc grooves 51 and vertical grooves 52, which together constitute a complex heating and cooling network. The design of the grooves not only optimizes the layout of the circulation pipeline 4, but also improves the heat transfer efficiency, so that heat or cold can be more evenly distributed over the entire ground. The vertical air guide branch 5 is located on the left and right card plates 21 and 22 and is close to the wall side of the building main body 1. The end of the vertical air guide branch 5 is connected to the bottom of the ventilation system 11. The ventilation system 11 introduces fresh air into the room and draws the indoor air into the prefabricated floor heating groove module 2. This step is a key step in dehumidifying the prefabricated floor heating groove module 2. The air then flows back to the air purifier through the grooves. The purified and dehumidified gas is circulated into the room, and the filtered gas is discharged to the outside, thereby achieving purification and renewal of the indoor air.

[0023] The circulation pipe 4 is laid along the groove on the prefabricated floor heating groove module 2 and its end is connected to the external pipe. The circulation pipe 4 is a key component in the heating and cooling system. It transfers heat or cold from the external pipe to the ground. Hot water, cold water or other heat transfer media flows inside the circulation pipe 4. These media flow in the pipe through the action of the circulation pump under the regulation of the external control system to achieve heat transfer and exchange, thereby achieving indoor heating and cooling. It also includes: Connecting part: The connecting part is provided on the left card plate 21, the outer ring card plate 23, the right card plate 22, the connecting card plate 24 and the inner ring card plate 25. The connecting part is used to connect adjacent plates; Buffer support assembly: The buffer support assembly is arranged above the connection portion and is used to provide buffer support for the circulation pipeline 4; Pipeline detection component: The pipeline detection component is arranged on the buffer support component, and the pipeline detection component can perform aging detection on the circulation pipeline 4.

[0024] Furthermore, the insulation layer is composed of an overhead module 3, an adjustable anchor bolt 31 and an insulation board 32. The upper end of the adjustable anchor bolt 31 is rotatably engaged with the overhead module 3, and the lower end of the overhead module 3 extends to the interior of the floor slab at the bottom of the building body 1 and is threadedly connected thereto. The adjustable anchor bolt 31 allows the height of the overhead module 3 to be fine-tuned to adapt to different ground conditions or construction requirements. The overhead module 3 serves as the basic support structure of the insulation layer and is designed to create a certain air layer to reduce heat loss through direct contact with the floor slab. At the same time, pipelines can also be laid under the overhead module 3. A mesh grille is provided in the middle of the overhead module 3. The insulation board 32 is made of graphite-grade EPS (expanded polystyrene). The insulation board 32 is embedded in the mesh grille. EPS (expanded polystyrene) has excellent thermal insulation performance and is lightweight and environmentally friendly. The addition of graphite further improves the thermal conductivity of EPS, enabling it to achieve higher thermal insulation effect at a lower density. The insulation board 32 is embedded in the mesh grille of the overhead module 3 to form a continuous insulation layer, which effectively blocks the transfer of heat.

[0025] The connecting part is composed of a slot 53 and an insert block 54. The outer ring card plate 23, the connecting card plate 24 and the inner ring card plate 25 are respectively connected to the two sides of the slot 53 and the insert block 54. The left card plate 21 and the right card plate 22 are a left and right positive and negative pair. The side wall of the left card plate 21 facing the outer ring card plate 23 is provided with a slot 53, and the side wall of the right card plate 22 facing the outer ring card plate 23 is provided with an insert block 54. The slot 53 and the insert block 54 are matched with each other, and the slot 53 and the insert block 54 are slidingly connected. The slot 53 and the insert block 54 are designed to match each other, and a close connection between the modules is achieved by sliding connection. This connection method not only simplifies the installation process and improves work efficiency, but also ensures the firmness and stability of the connection between the modules. At the same time, it allows a certain amount of thermal expansion and contraction, thereby enhancing the durability and reliability of the system.

[0026] It should be noted that the prefabricated floor heating groove module 2 cut according to the terrain is installed on the overhead module 3 after being assembled and spliced. According to the terrain conditions and design requirements, the prefabricated floor heating groove module 2 is cut and assembled and spliced ​​through the connection part of the slot 53 and the plug block 54. Then, the assembled module is installed on the overhead module 3 to form a complete heating and cooling floor structure. The covering layer 27 is a fiber-reinforced calcium silicate board. The fiber-reinforced calcium silicate board has high strength, fire resistance, moisture resistance and other properties, which can effectively protect the lower structure from damage from the external environment. The decorative surface layer 26 can be selected from ceramic tiles, stones, wooden floors, etc. Users can make comprehensive considerations and choices based on their own needs, budgets, construction technology and other factors.

[0027] In this embodiment, the prefabricated floor heating groove module 2 is composed of a left-side card plate 21, an outer ring card plate 23, a right-side card plate 22, a connecting card plate 24 and an inner ring card plate 25, which are assembled and spliced ​​through a connecting part (slot 53, plug-in block 54). This modular design facilitates construction and installation, improves work efficiency, and is also convenient for later maintenance and replacement. The several grooves set on the prefabricated floor heating groove module 2 serve as channels and air ducts for the circulation pipeline 4. The ventilation system 11 introduces fresh air into the room and is connected to the prefabricated floor heating groove module 2 through the vertical air guide branch 5. The ventilation system 11 can also suck indoor air into the prefabricated floor heating groove module 2 for dew and defrosting, and then return it to the air purifier through the groove for purification and dehumidification, and finally circulate it to the room or be discharged to the outdoors.

[0028] Heat is transferred through the heat medium (such as water or other heat carrier) in the circulation pipe 4. The heat medium is heated to a certain temperature under the regulation of the external control system. The heated heat medium flows in the circulation pipe 4 and transfers the heat to the prefabricated floor heating groove module 2. The surface and groove of the prefabricated floor heating groove module 2 are coated with a heat-conductive waterproof coating, which significantly improves the thermal conductivity and transfers the heat to the ground faster. The ground (decorative surface layer 26) serves as the final heat transfer medium and dissipates the heat to the indoor space. The heat is evenly distributed through ground radiation and convection. Distributed throughout the entire indoor space to achieve a heating effect; cooling is similar to heating, and the cold is also transferred through the refrigerant in the circulation pipe 4. The refrigerant is cooled to a certain temperature under the regulation of the external control system. The cooled refrigerant flows in the circulation pipe 4, transferring the cold to the prefabricated floor heating groove module 2. The ground (decorative surface layer 26) absorbs the heat in the room and transfers the heat to the refrigerant through the prefabricated floor heating groove module 2 and the circulation pipe 4. The refrigerant takes the absorbed heat to the external system for processing, thereby lowering the indoor temperature and achieving a cooling effect.

[0029] The insulation layer consists of an overhead module 3, adjustable anchor bolts 31 and insulation boards 32, which create a certain air layer to reduce heat loss and can effectively reduce noise. It is also easy to level. By adjusting the height of the anchor bolts, a uniform and stable gap can be ensured between the insulation layer and the floor slab, thereby avoiding a decrease in the insulation effect due to uneven ground. In addition, the adjustability also facilitates fine-tuning during the installation process to adapt to different ground conditions. A mesh grille is provided in the middle of the overhead module 3, which is embedded with a graphite-grade EPS (expanded polystyrene) insulation board 32 to form a continuous insulation layer that effectively blocks heat transfer. The insulation layer is designed to reduce heat loss through direct contact with the floor slab and improve the insulation performance of the system.

[0030] In summary, this ventilation and insulation module heating and cooling floor realizes the functions of heating, cooling, ventilation and insulation through clever structural design and material selection. The modular design makes construction and installation simpler and more efficient. Through the connection method of slots 53 and plugs 54, the modules can be tightly connected together to form a complete heating and cooling floor structure. Based on the transfer of heat and cold, the heat dissipation and heat absorption of the ground and the operation of the ventilation system 11, it can effectively remove dew and defrost, providing users with a comfortable, energy-saving and environmentally friendly indoor environment. The design of the insulation layer not only reduces the problem of heat loss through direct contact with the floor, but also enhances the overall insulation effect due to the presence of the air layer. At the same time, the combination of the overhead module 3 and the insulation material also provides an effective noise reduction effect, making the indoor environment quieter and more comfortable.

[0031] Example 2, refer to Figures 6-10 The buffer support assembly includes a mounting plate 6, a plurality of connecting chambers 71 are fixedly connected to the lower side wall of the mounting plate 6, an outer tube body 7 is fixedly connected to the lower side of the connecting chamber 71, a plurality of support tubes 72 are arranged inside the outer tube body 7, and the interior of the outer tube body 7 is filled with nitrogen.

[0032] Furthermore, the mounting plate 6 is located above the connection between the left-path clamping plate 21 and the right-path clamping plate 22, and the outer tube body 7 is arranged in a U-shape and wrapped around the outside of the circulation pipeline 4. This wrapping design provides additional protection and support for the circulation pipeline 4. The arrangement of the support tube 72 further enhances the stability of the structure while allowing gas to circulate inside to provide additional buffering effect. The inner cavity of the support tube 72 is connected to the inner cavity of the outer tube body 7, and the side wall of the outer tube body 7 fits the outer wall of the circulation pipeline 4. The support tube 72 and the outer tube body 7 are both made of flexible materials, so that the entire buffer support assembly can provide effective support while also being able to adapt to the slight deformation of the circulation pipeline 4 caused by temperature changes, which helps to extend the service life of the circulation pipeline 4 and reduce potential failures caused by vibration or displacement.

[0033] It should be noted that the side wall of the outer tube body 7 that is in contact with the circulation pipeline 4 is coated with a high thermal conductivity coating. The thermal conductivity of the high thermal conductivity coating is greater than the thermal conductivity of the thermally conductive waterproof coating. Therefore, it can more effectively transfer the heat generated by the circulation pipeline 4 to the outer tube body 7 and the air around it, thereby achieving more effective heat dissipation.

[0034] In this embodiment, the mounting plate 6 serves as a fixed base for the entire buffer support assembly and is connected to the outer tube body 7 through a plurality of connecting chambers 71, thereby ensuring the stability of the entire assembly. The outer tube body 7 is arranged in a U-shape and tightly wrapped around the outer side of the circulation pipeline 4, providing additional protection and support for the circulation pipeline 4. The arrangement of the support tubes 72 further enhances the stability of the structure. They are connected to the inner cavity of the outer tube body 7, allowing gas to circulate inside. This design not only enhances the overall rigidity of the structure, but also provides additional buffering effect to protect the circulation pipeline 4 from damage.

[0035] During operation, the circulation pipeline 4 will experience thermal expansion and contraction due to temperature fluctuations of the fluid, causing slight deformation of the pipeline itself. The support tube 72 and the outer tube body 7 are made of flexible materials, which can adapt well to the deformation caused by temperature changes, reducing the direct impact and potential damage of the deformation on the circulation pipeline 4 itself; the flexible material has good elasticity and recovery. When the circulation pipeline 4 is deformed, the flexible support tube 72 and the outer tube body 7 can absorb and disperse this part of the deformation energy, reducing the transmission of deformation to other parts, which helps to maintain the stability and reliability of the entire system and avoid problems such as structural loosening, increased vibration or leakage caused by deformation transmission; by reducing deformation transmission, the flexible support tube 72 and the outer tube body 7 help to reduce fatigue damage to the circulation pipeline 4 and its connecting components, thereby extending the service life of the entire system. In addition, the flexible material can also alleviate the stress concentration caused by vibration or external force impact to a certain extent, further protecting the safe operation of the circulation pipeline 4.

[0036] When the circulation pipeline 4 is working, the heat it generates will be transferred to the outer tube body 7 by heat conduction. Since the outer tube body 7 is filled with nitrogen and the side wall is coated with a high thermal conductivity coating, the heat can be quickly absorbed by the nitrogen and dissipated into the surrounding environment through the outer tube body 7. At the same time, the provision of the support tube 72 also promotes the internal circulation and dissipation of heat, further enhancing the heat dissipation effect. On the other hand, the heating or cooling of the nitrogen will also cause the gas to expand or contract accordingly.

[0037] Example 3, refer to Figures 8-12The pipeline detection assembly includes an installation cavity 61 provided in the installation plate 6, the installation cavity 61, the outer tube body 7 and the inner cavity of the connecting chamber 71 are connected, the connecting chamber 71 is slidably provided with an arc-shaped slider 8, the upper side wall of the arc-shaped slider 8 is fixedly connected to the trigger magnetic plate 81, the installation cavity 61 is fixedly installed with a limit rod 9 and a scale sensing member 94, a sliding magnetic plate 92 is slidably connected to the limit rod 9, the end of the limit rod 9 facing the trigger magnetic plate 81 is fixedly connected to the limit block 91 for limiting the sliding magnetic plate 92, the side wall of the sliding magnetic plate 92 away from the limit block 91 is fixedly connected to a connecting spring 93, the end of the connecting spring 93 is fixedly connected to the side wall of the installation cavity 61, the connecting spring 93 is sleeved on the outer side of the limit rod 9, and the side wall of the sliding magnetic plate 92 facing the scale sensing member 94 is provided with a pointer 921, and the sliding magnetic plate 92 on the same side and the opposite surface of the sliding magnetic plate 92 are magnetically arranged with the same polarity.

[0038] It should be noted that the magnetic force between the sliding magnetic plates 92 on different sides can be ignored.

[0039] Furthermore, the side wall of the sliding magnetic plate 92 is against the side wall of the mounting cavity 61, ensuring the stability of the movement trajectory of the sliding magnetic plate 92, and the end of the pointer 921 is against the scale surface of the scale sensing component 94. The pointer 921 is electrically connected to the scale sensing component 94. The scale sensing component 94 reads through the pointer 921 and judges the status of the circulation pipeline 4 based on the reading. The scale sensing component 94 is electrically connected to the external control system. When the scale sensing component 94 reads a reading that is not within the safety threshold range, it will issue an alarm through the external control system to prompt the staff to inspect and maintain the circulation pipeline 4.

[0040] It should be noted that when the circulation pipeline 4 is normal, the upper end of the trigger magnetic plate 81 is located in the middle of the installation cavity 61. At this time, the sliding magnetic plate 92 is subjected to the magnetic force of the trigger magnetic plate 81 on the same side (small), and the connecting spring 93 is in an incompletely compressed state. When the circulation pipeline 4 is normal, the pointer 921 is in the middle of the scale of the scale sensing component 94. The middle of the scale of the scale sensing component 94 is a safe area, and the two ends are alarm areas. When the pointer 921 is located in the middle of the scale (safe area), it indicates that this section of the circulation pipeline 4 is normal. When the pointer 921 is located at both ends of the scale (alarm area), it indicates that this section of the circulation pipeline 4 is aging or damaged and needs to be repaired. When the trigger magnetic plate 81 is completely in the connecting chamber 71, the side wall of the sliding magnetic plate 92 is against the limit block 91. At this time, the sliding magnetic plate 92 is no longer subjected to the magnetic force of the trigger magnetic plate 81 on the same side. Under the elastic force of the connecting spring 93, the sliding magnetic plate 92 moves to against the limit block 91.

[0041] In this embodiment, when the circulation pipeline 4 is normal, the upper end of the trigger magnetic plate 81 is located in the middle of the installation cavity 61. At this time, the sliding magnetic plate 92 is subjected to the smaller magnetic force of the trigger magnetic plate 81 on the same side, and is simultaneously subjected to the elastic force of the incompletely compressed state of the connecting spring 93, and is maintained in a relatively stable position. The pointer 921 is located in the middle of the scale of the scale sensing component 94, that is, the safe area.

[0042] Detection process: When the state of the circulation pipeline 4 changes due to aging or damage, there are two situations: the circulation pipeline 4 provides heating or cooling, and the position of the triggering magnetic plate 81 will change accordingly.

[0043] When the circulation pipeline 4 is providing heating, due to the aging of the pipeline (its thermal conductivity is stronger than that in normal state), and the thermal conductivity coefficient of the high thermal conductivity coating is greater than that of the thermal conductive waterproof coating, it can more effectively transfer the heat generated by the circulation pipeline 4 to the outer tube body 7. At this time, the nitrogen inside the outer tube body 7 will expand due to heat (the greater the degree of aging, the greater the degree of expansion), and the expanded gas will push the trigger magnetic plate 81 to move upward. Due to the increase in the facing area, it will produce a greater magnetic force on the sliding magnetic plate 92, causing the sliding magnetic plate 92 to slide on the limit rod 9. At the same time, the connecting spring 93 will be subjected to more compression, and the movement of the sliding magnetic plate 92 will drive the pointer 921 to move on the scale of the scale sensing component 94, thereby changing the reading. The greater the degree of aging, the greater the distance the sliding magnetic plate 92 moves, and the greater the change in the reading. When the reading exceeds the predetermined threshold, it means that this section of the pipeline needs to be repaired.

[0044] When the circulation pipe 4 is supplying cooling, due to the aging of the pipe (compared to the normal state, its cooling capacity is stronger), the nitrogen inside the outer tube body 7 will shrink when it is cold (the greater the degree of aging, the greater the shrinkage). The shrinking gas will cause the support tube 72 to shrink. Correspondingly, under the action of gravity, the trigger magnetic plate 81 will also drop. The greater the degree of aging, the greater the degree of drop of the trigger magnetic plate 81. At this time, the area facing the sliding magnetic plate 92 and the trigger magnetic plate 81 on the same side will be reduced accordingly, which will produce a smaller magnetic force on the sliding magnetic plate 92. The sliding magnetic plate 92 slides along the limit rod 9 toward the limit block 91 under the elastic force of the connecting spring 93. At this time, the reading of the pointer 921 changes. When the trigger magnetic plate 81 is completely in the connecting chamber 71, the side wall of the sliding magnetic plate 92 will be against the limit block 91. At this time, the sliding magnetic plate 92 is no longer affected by the magnetic force of the trigger magnetic plate 81 on the same side, but moves to the position against the limit block 91 under the elastic force of the connecting spring 93. In this case, the area where the pointer 921 is located is the alarm area.

[0045] Reading judgment and alarm: The scale sensor 94 judges the status of the circulation pipeline 4 through the reading of the pointer 921. If the reading is in the middle of the scale (safe area), it means that this section of the circulation pipeline 4 is normal. If the reading is at both ends of the scale (alarm area), it means that this section of the circulation pipeline 4 may be aged or damaged and needs to be repaired. When the scale sensor 94 reads a reading that is not within the safety threshold range, it will issue an alarm through the external control system to prompt the staff to repair and maintain the circulation pipeline 4.

[0046] By means of the magnetic force of the triggering magnetic plate 81 and the sliding magnetic plate 92 and the elastic force of the connecting spring 93, the state changes of the circulation pipeline 4 can be monitored in real time. Whether it is heating or cooling, the aging or damage of the pipeline will cause the position of the triggering magnetic plate 81 to change, thereby causing the sliding magnetic plate 92 and the pointer 921 to move, thereby realizing real-time monitoring of the state. Through the real-time monitoring and early warning mechanism, the device can promptly discover and deal with potential problems of the circulation pipeline 4 to avoid the occurrence of safety accidents; different degrees of aging will cause different moving distances of the triggering magnetic plate 81, thereby causing different changes in the reading of the pointer 921. This change can accurately reflect the actual state of the pipeline, and the device is suitable for the detection of the circulation pipeline 4 under two different working conditions of heating and cooling, and can meet different usage requirements without replacement or adjustment.
