Description

Technical Field

[0001] This invention relates to the field of waterless air conditioning technology, and more specifically, to a tubular distributor for a waterless radiant air conditioning system and its installation method. Background Technology

[0002] Waterless radiant air conditioning is a new product developed and promoted in recent years. It can replace air conditioning, combining the advantages of both air conditioning and heat pumps. It is a preferred (technical solution) for modern, five-constant, comfortable homes, boasting a high energy efficiency ratio (above 1:6), powerful functions (organically integrated with the building structure to achieve indoor radiant heat exchange), and requiring no water. It significantly enhances the application capabilities of reverse Carnot cycle units, representing a revolutionary innovation in the field of refrigeration and HVAC technology. It uses a compressor to drive the refrigerant to circulate within the system and relies on radiant tubes (radiant panels) within the building to complete the conversion of latent heat energy through phase change, achieving indoor heating and cooling without consuming water resources. This technology also benefits from its ease of installation and maintenance, and wide applicability, making it a preferred system for residential homes and small to medium-sized commercial buildings. Its water-saving and convenience characteristics further highlight its application value, especially in arid and water-scarce areas with poor water quality; and its energy-saving and comfort characteristics further emphasize its application value in the recently promoted "five-constant" home and prefabricated building systems.

[0003] However, waterless radiant air conditioning systems still have certain shortcomings in the layout and installation of indoor building structures, both above and below ceilings and on the floor. For example, since all indoor radiant pipes need to be centrally connected to a fixed distribution box or distributor, when the number of pipes (more than ten) increases, it becomes extremely difficult to arrange the dense pipes in a limited local space. This can easily lead to uneven heat dissipation, low installation efficiency, problems such as cross-layouts, stress concentration at bends, and insufficient space for maintenance. Summary of the Invention

[0004] The purpose of this invention is to provide a tubular distributor for a waterless radiant air conditioning system and its installation method to solve the aforementioned technical problems.

[0005] The present invention solves the above-mentioned technical problems through the following technical solutions: This invention provides a tubular distributor for a waterless radiant air conditioning system, comprising: The indoor unit is located indoors and is used for dehumidification and cooling. The function box is located outdoors and is connected to the interface on the outdoor unit of the air conditioner through pipes. The function box is provided with several linearly evenly distributed pipe interfaces. At least one piping distribution assembly, located indoors, includes a distribution pipe 1 and a distribution pipe 2 connected to a piping interface on a functional box. The distribution pipe 1 includes a bent section that bends at 180 degrees, and the distribution pipe 2 includes a horizontally arranged smooth section. Both the bent section and the smooth section are provided with multiple linearly distributed connecting pipes, and the connecting pipes on the distribution pipe 1 and the distribution pipe 2 are arranged alternately in sequence. Multiple dielectric conduction components include a radiating plate and a dielectric conduction tube coiled on the radiating plate. The two ends of the dielectric conduction tube are respectively connected to two adjacent connecting tubes on distribution tube one and distribution tube two to form an independent loop unit.

[0006] Preferably, the connecting tube is an S-shaped capillary tube with a ferrule at its end, and the medium conduction tube is detachably connected to the connecting tube through the ferrule.

[0007] Preferably, the inner diameter of the output distribution pipe 2 is greater than or equal to the inner diameter of the input distribution pipe 1.

[0008] Preferably, the lengths of the first distribution pipe and the second distribution pipe are equal, ranging from 1.5 to 150 m.

[0009] Preferably, the medium conduction tube is fixed inside the radiating plate in a preset bent coil posture.

[0010] Preferably, the lengths of the bent section and the smooth section can be adjusted according to the actual usage, and the lengths of the bend in the bent section and the end point of the smooth section are consistent.

[0011] Preferably, both the first distribution pipe and the second distribution pipe are metal pipes with a diameter of 6 to 80 mm.

[0012] A method for installing a waterless radiant air conditioning system includes the following steps: S100. Install the function box outdoors and connect it to the outdoor unit of the air conditioner; S200. Lay multiple media conduction components on the indoor floor; S300. Install the piping distribution assembly along the skirting board, so that distribution pipe one and distribution pipe two are respectively connected to the other input end and the other output end of the distribution piping of the function box; S400. After the medium conduction component connecting the distribution pipe one and distribution pipe two of the pipeline distribution assembly has been operating normally for a period of time, an anti-corrosion and heat-insulating coating is required. S500. Connect both ends of the medium conduction tube of each medium conduction component to the adjacent connecting tubes on distribution tube 2 and distribution tube 1 respectively, to form a parallel closed loop.

[0013] Preferably, a medium conduction component is added to the interior wall to form a vertical or horizontal action unit, and a corresponding pipe distribution component is configured so that the medium conduction components on the wall and the ground together constitute a cooling / heating surface; A medium conduction component is added to the indoor ceiling to form a top-operating unit, and a concealed piping distribution component is configured so that the medium conduction components on the ceiling and the ground can form a cooling / heating surface individually or together.

[0014] Preferably, during cooling, the top-mounted unit is the main circuit, and the wall and floor units are auxiliary circuits; during heating, the floor and wall units are the main circuits, and the top-mounted unit is the auxiliary circuit.

[0015] The beneficial effects of this invention are as follows: This invention connects the pipeline distribution components directly to the functional box, allowing each medium conduction pipe to connect directly to the distribution components, eliminating the need for an intermediate distributor box structure. On one hand, since multiple pipeline distribution components can be connected to corresponding medium conduction components, the pipelines can be arranged separately, greatly reducing the difficulty of pipeline layout and organization compared to the traditional centralized pipeline arrangement using a distributor box. On the other hand, dividing the medium flow loop into several small loop units with equal spacing between each small loop unit improves the uniformity of the building's radiant surface, shortens the path length of each "remote" loop, and enhances the overall performance of the system.

[0018] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0019] Example 1 Please refer to the following: Figures 1 to 3A tubular distributor for a waterless radiant air conditioning system includes: an indoor unit, a function box 100, a pipe distribution assembly 200, and multiple media transmission assemblies 300; the function box 100 is installed outdoors, such as on a balcony (indoor or outdoor), near the outdoor unit of the air conditioner, and the input and output ends of the function box 100 are respectively connected to the outdoor unit of the air conditioner through pipes.

[0020] The pipeline distribution assembly 200 (at least one) is located indoors, typically installed at the baseboard position. It is mainly used to connect with the media conduction assembly 300 to form a complete media flow loop. The pipeline distribution assembly 200 includes a first distribution pipe 201 and a second distribution pipe 202 that are connected to the function box 100 respectively. The ends of both are detachably connected to the pipeline interface (stop valve) of the function box 100. The pipeline distribution assembly 200 includes a first distribution pipe 201 and a second distribution pipe 202 connected to the pipeline interface (stop valve) on the functional box 100. The first distribution pipe 201 includes a bent section with a 180-degree bend, and the second distribution pipe 202 includes a horizontally arranged smooth section. Both the bent section and the smooth section are provided with multiple linearly non-uniformly distributed connecting pipes 203, and the connecting pipes 203 on the first distribution pipe 201 and the second distribution pipe 202 are arranged alternately. The distance between adjacent connecting pipes on the first distribution pipe and the second distribution pipe is 20 to 1000 mm. Both the first distribution pipe and the second distribution pipe are metal pipes with a diameter of 6 to 80 mm, such as copper pipes. The inner diameter of the second distribution pipe is greater than or equal to the inner diameter of the first distribution pipe. The connecting pipe 203 adopts an S-shaped bend capillary tube with a length of 100 to 500 mm. The end of the connecting pipe 203 is provided with a nail connector 204 (a key sealing fastener for connecting metal pipes). After installation, the nail connector 204 is located outside the medium transmission assembly 300, which facilitates quick installation and disassembly of the medium transmission assembly 300, and is convenient for inspection and maintenance. It also has good sealing performance. The connecting pipe and the medium transmission pipe can be metal or non-metal or any combination of metal and non-metal.

[0021] The medium conduction component 300 is generally laid on the indoor floor. The medium conduction component 300 includes a radiant plate 301 and a medium conduction pipe 302. Its basic size is 600×2400mm, and the size can be adjusted according to actual usage requirements. One to N medium conduction pipes 302 can be arranged inside it. The medium conduction pipes 302 are arranged on the radiant plate 301 in a preset coiled posture and are connected to the connectors 204 of the two adjacent connecting pipes 203 on the distribution pipe 1 201 and the distribution pipe 2 202, respectively. The medium conduction pipes 302 are made of 2-5mm copper pipes, and their coiled posture includes S-type or M-type (the basic type). The S-type or M-type arrangement allows the pipe body of the medium conduction pipe 302 to be evenly distributed in the radiant plate 301, so that the heat or cold energy carried by the medium flowing inside can be evenly transferred to the radiant plate 301 to achieve a "constant and uniform" cooling and heating effect in the building interior.

[0022] Additionally, it should be noted that in actual use, the installation position and quantity of the medium conduction components 300 can be flexibly adjusted according to the size of the indoor area. The pipe distribution components 200 will be configured accordingly based on the position and quantity of the medium conduction components 300 to ensure that the system can operate efficiently and stably, providing a suitable temperature environment for the indoor space and achieving a "five constants" modern home environment.

[0023] The above scheme is used as follows: When the outdoor unit of the air conditioner is running, the cold / heating medium it generates is transmitted to the function box 100 through the output pipe. After the "conversion processing" of the function box 100, the cold / heating medium enters the distribution pipe 202 from the other output end of the function box 100. Since the distribution pipe 202 is provided with several linearly uniformly arranged connecting pipes 203 that are staggered and equidistantly distributed with the distribution pipe 201, the cold / heating medium will enter the medium conduction pipe 302 in the medium conduction assembly 300 connected to it through the connectors 204 on these connecting pipes 203.

[0024] The medium conduction pipe 302 is evenly arranged on the radiant plate 301 in an S-shaped or M-shaped coil. During the flow of the cold / heat medium in the medium conduction pipe 302, the cold or heat energy it carries is evenly transferred to the radiant plate 301. The radiant plate 301 then transfers the cold / heat to the indoor space in the form of radiation, thereby realizing indoor cooling or heating.

[0025] It should be noted that regarding the structure of the radiant panel, the thickness of the radiant panel is generally 3-12mm, and the grooves inside the radiant panel need to be filled with heat-conducting material as needed; the radiant panel is made of metal, non-metal, or a combination of metal and non-metal; and the back of the radiant panel can be equipped with a heat-insulating material protective layer, the thickness of which is generally 1-50mm, while the front of the radiant panel can be equipped with a decorative layer; the radiant panel is made by combining heat-conducting material plates with pipes, or by pressing together two heat-conducting plates with pipes of different shapes and sizes between them; the width of the radiant panel is customized according to the dimensions required by the project, but the length of all pipes in the radiant panel must be basically the same.

[0026] After the latent heat energy exchange of phase change is completed in the medium conduction pipe 302, the medium will flow back to the distribution pipe 201 through the connecting pipe 203 on the other end of the distribution pipe 201, and finally return to the other input end of the function box 100. Then, it will return to the air conditioner outdoor unit through the pipe connected to the output end of the function box 100, thus completing a complete cycle.

[0027] The installation method for the above-mentioned waterless radiant air conditioning system is as follows: S100. Function Box Installation Fix the function box 100 to the outdoor wall (or inside the balcony) or equipment platform, ensuring it is within the nearest range of the air conditioner outdoor unit (greater than 10cm). Connect the input and output terminals of the function box 100 respectively through two pre-insulated copper pipes, using shut-off valves at the connection points. After completion, perform a 24-hour pressure test on the connecting pipes (test pressure 4.0 MPa).

[0028] S200. Ground radiant unit installation Substrate preparation: The base ground is leveled to meet the requirements for indoor flooring installation, and an insulation layer (generally 1-50mm) is laid at the same time. Radiant panel installation: Lay the radiant panels of the medium conduction component 300 flat on the ground according to the design spacing. The standard size of the radiant panel is 600×2400mm (and other sizes). Multiple medium conduction tubes 302 made of metal (or non-metallic composite) are pre-embedded inside, and the coils are evenly distributed in S-shape or M-shape. Pipeline protection: The radiant panels are locked together with latches. For pipelines without radiant panels, an anti-corrosion film (plastic) coating can be laid on them and covered with a 5-100mm cement mortar thermal conductive leveling layer. Finally, flooring or other finishing layers are laid on the radiant panels or cement layer.

[0029] S300. Pipeline Distribution Component Positioning Install pipe distribution components 200 along the baseboards, light troughs, and vertical corners of the interior walls (both longitudinal and transverse): The connecting pipes of distribution pipe 1 201 and distribution pipe 2 202 can be fixed in parallel on the fixed bracket inside the skirting board at a height of 50-150mm from the ground, for ease of installation. The two pipes extend outdoors and connect to the corresponding interfaces of the functional box 100. The connection method is to use a nail head flange for sealing and fastening. Key layout: The connecting pipes 203 on the first distribution pipe 201 and the second distribution pipe 202 are bent in an S-shape, and the connecting pipes 203 of the two pipes are staggered and equidistantly distributed (under normal circumstances).

[0030] S400. Circuit Construction and Sealing Radiation tube connection: Connect the two ends of the medium conduction tube 302 in each radiation plate 310 to the adjacent and staggered connecting tubes 203 on the second distribution tube 202 and the first distribution tube 201 respectively to avoid stress and make reasonable connection. Example: The connection between the input end of the first radiant plate and the connecting pipe of the second distribution pipe 202, and the connection between the output end and the connecting pipe of the first distribution pipe 201, is generally 300-600mm. Quick sealing: By tightening the corresponding joint of the medium transmission pipe 302 through the nail joint 204 at the end of the connecting pipe 203, the mechanical seal torque is ≤15N·m; S500. System Debugging Pressurize between another output terminal and another input terminal of the function box 100 at 6-8 MPa and maintain the pressure for more than 48 hours; Once the pressure holding is complete (in the original position and open the corresponding shut-off valve of function box 100), vacuum for at least 30 minutes; Charge the system with refrigerant to the design pressure (this step can be omitted as the refrigerant carrying capacity of each unit varies); Start the outdoor unit of the air conditioner 400. After the temperature is balanced, adjust the flow cut-off valves of each distribution pipe 201 and distribution pipe 202 to make the temperature difference of each circuit ≤1℃. The surface temperature uniformity of the 310 ground radiant panel is generally found to fluctuate within ±0.5℃ within a 1m² range.

[0031] Example 2 As another embodiment of the present invention, the difference from Embodiment 1 is that a medium conduction component 300 is also evenly laid on the four walls of the room. The medium conduction component 300 laid on the four walls forms a vertical (or horizontal) action unit, which is also equipped with a suitable pipe distribution component 200. Together with the medium conduction component 300 laid on the ground to form a ground action unit, it works to realize the cooling and heating functions of the room. Compared with the single ground method in Embodiment 1, its cooling and heating effect is better. It mainly relies on the principle of Lambert's residual glare law, which has the largest radiation normal emission angle coefficient of the wall surface. When cooling the room, the radiative cooling effect generated by the wall is greater than that of the ground to reduce the temperature of the indoor environment and prevent the low ground temperature from being transmitted to the lower limbs of the human body and causing discomfort, especially for the elderly and children with weaker constitutions. Therefore, this embodiment, in addition to ensuring normal cooling and heating functions, further improves the comfort of the human body in the room.

[0032] Example 3 In another embodiment of the present invention, the difference from Embodiment 1 is that a medium conduction component 300 is laid on the indoor ceiling, forming a top-mounted working unit. A suitable pipe distribution component 200 is also configured thereon, which can be concealed within a light trough where the ceiling meets the wall. Compared to Embodiment 1, its cooling and heating effects are of a high standard of comfort. During cooling, the medium conduction component 300 on the ceiling plays a primary role, while the medium conduction component 300 on the ground plays a secondary role. During heating, the medium conduction component 300 on the ceiling plays a secondary role, while the medium conduction component 300 on the ground plays a primary role.

[0033] The tubular distributor provided by this invention has the following effects: By eliminating the limitations of traditional distributor boxes, the flexible configuration of the pipe distribution component 200 and the medium conduction component 300 enables efficient distribution and circulation of the medium within the room. The position and quantity of the medium conduction component 300 and the pipe distribution component 200 can be flexibly adjusted according to the room size, allowing the system to adapt to different usage scenarios and exhibiting strong versatility and adaptability. Simultaneously, it expands the installation options for the air conditioning system, allowing selective installation on the floor, walls, and ceiling, broadening the application range and effectiveness of the pipe distributor. In Example 2, the combined effect of the wall and floor medium conduction components 300 avoids discomfort caused by excessively low floor temperatures, improving human comfort and reducing power consumption. In Example 3, the ceiling medium conduction component 300, working in conjunction with the floor medium conduction component 300 according to different cooling and heating needs, achieves a higher standard of comfort.

[0034] In summary, the tubular distributor and its installation method for the waterless radiant air conditioning system of the present invention can be combined in various ways, such as on the ground, walls, ceilings, ground and walls, ground and ceilings, ground, walls and ceilings, and walls and ceilings. Through innovative structural design and flexible application methods, it provides a highly efficient, comfortable, stable and energy-saving "five constants" home system solution for indoor cooling and heating of waterless radiant air conditioning systems, and has broad market application prospects. Example 4 As another application scenario of this invention, radiant panels are arranged on the building's outer envelope using tubular distributors, directly blocking the "intrusion" of external cold and heat sources to meet the building's energy consumption and usage requirements. The area of ​​the outer envelope of a high-rise building is approximately one-third of the building's total area. By "defending" the outer envelope of a high-rise building, the area required for radiant panel installation can be saved, while also improving the building's energy efficiency. It can also be installed on the exterior (or interior) structural surface of a building wall as a radiant heat exchange structure. In specific installation, the medium conduction pipe is first installed on the radiant plate, and then the radiant plate is laid on the exterior wall of the building with the back facing the interior. The front is covered with thermal insulation material with a thickness of 2~500mm (depending on the region). The exterior (top) is then covered with exterior wall decoration material. In this way, a heat radiation heat exchange structure is formed on the exterior envelope of the building, which then radiates heat into the interior. Furthermore, the extended medium conduction pipe can be combined with the pipe distribution components on the interior floor to form an "interlocking" system that supplies heating and cooling to the interior from the exterior building, thereby improving the overall heat exchange effect of the unit.

[0035] The embodiments of the present invention have been described above, but the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention, all of which are within the protection scope of the present invention.
