Description

Technical Field

[0001] This utility model relates to the field of heating, ventilation and air conditioning, specifically to a ring-shaped water pipe system for indoor large-space radiant panels. Background Technology

[0002] In the field of radiant air conditioning, the uniformity of radiant surface temperature has always been a key focus for industry professionals. This is because uniformity ensures consistent temperature across the lateral (not vertical) direction within an indoor radiant area, thus improving thermal comfort. Currently, the largest proportion of radiant air conditioning system applications in China are in residential buildings, where the maximum area of ​​functional rooms typically does not exceed 50m². 2 Therefore, the issue of the uniformity of radiation surface temperature has not received sufficient attention. Figure 1 The design of the existing water pipe system is illustrated. There is only one main supply and return pipe (location A). The entire radiant panel system has multiple branch pipes, and each branch pipe connecting to a different radiant panel contains multiple panels. This causes an imbalance in the water supply hydraulics of the entire radiant panel system, leading to several problems, including uneven temperature: the temperature rise / fall is greater towards the later radiant panels, resulting in significant differences in the radiant surface temperature and poor uniformity. Taking a heating radiant panel system as an example, specifically... Figure 1 The temperature is higher closer to point A and lower further away from point A. Point C is colder than point A, and point B is colder than point D. Point B, diagonally opposite A, has the lowest temperature, especially in larger rooms. Furthermore, because the system is not operating under optimal hydraulic conditions, some terminal radiant panels, such as those near point B, take longer to reach their set temperature, increasing energy consumption and reducing the overall system's energy efficiency ratio. Additionally, when there is hydraulic imbalance, some components (such as pumps and valves) may bear greater power consumption to compensate for the extra load caused by the imbalance, accelerating wear and shortening their lifespan. Hydraulic imbalance can also lead to excessively high water flow velocities in some pipes, causing vibration and noise, affecting the comfort of the user environment. Finally, to address these issues, the system may require frequent adjustments and repairs, increasing the complexity and cost of maintenance. Therefore, this pipe connection method is only suitable for small rooms. However, with the continuous expansion of radiant air conditioning system applications, projects such as villas and small public buildings are becoming increasingly common, and the area of ​​a single indoor functional room / area can easily exceed 50m². 2 In this situation, ensuring hydraulic balance in the water supply to the entire radiant panel system, thereby minimizing the temperature difference on the radiant surface—that is, the difference between the average and minimum temperatures—is a technical problem that urgently needs to be solved. Furthermore, Figure 1The piping arrangement in the building resulted in the need for large-diameter pipes for the main supply and return water pipes due to the large area they cover. Flow meters and electric regulating valves could not be installed on the supply and return water circuits of the room in the manifold, and could only be installed by branching pipes directly from the building's main supply and return chilled water pipes. Summary of the Invention

[0003] This invention provides a ring-shaped water pipeline system for indoor large-space radiant panels, which can solve the problem of hydraulic imbalance during the water supply process of existing radiant panel devices in large functional areas.

[0004] This utility model discloses an indoor large-space radiant panel ring water pipeline system for supplying water to a radiant panel device composed of multiple sets of radiant panels. Each set of radiant panels is supplied with water through a radiant panel supply branch pipe and returned through a radiant panel return branch pipe. The system includes a first radiant panel supply and return pipe group and a second radiant panel supply and return pipe group. The first radiant panel supply and return pipe group includes a first radiant panel supply pipe and a first radiant panel return pipe. The first end of each radiant panel supply branch pipe is connected to the first radiant panel supply pipe, and the first end of each radiant panel return branch pipe is connected to the first radiant panel return pipe. Each second radiant panel supply pipe group includes a second radiant panel supply pipe and a second radiant panel return pipe. The second end of each radiant panel supply branch pipe is connected to the second radiant panel supply pipe, and the second end of each radiant panel return branch pipe is connected to the second radiant panel return pipe.

[0005] Preferably, the connection points of the plurality of water supply branch pipes of the radiant panel and the first water supply pipe of the radiant panel are g11, g12...g1n in sequence, the direction of water flow in the first water supply pipe of the radiant panel is from g11 to g1n, and the connection points of the plurality of water supply branch pipes of the radiant panel and the second water supply pipe of the radiant panel are g21, g22...g2n in sequence, the direction of water flow in the second water supply pipe of the radiant panel is from g2n to g21.

[0006] Preferably, the first water supply pipe and the first water return pipe of the radiant panel are connected by a bypass pipe, and the second water supply pipe and the second water return pipe of the radiant panel are connected by another bypass pipe.

[0007] Preferably, the g11 end of the first water supply pipe of the radiant plate is connected to the first water supply pipe of the water distribution manifold, and the g2n end of the second water supply pipe of the radiant plate is connected to the second water supply pipe of the water distribution manifold.

[0008] Preferably, the first water supply pipe and the second water supply pipe are of the same length.

[0009] As a preferred option, both the first and second water supply pipes for the distribution system are equipped with flow meters and electric regulating valves.

[0010] Preferably, the g1n end of the first water supply pipe of the radiant plate is connected to the third water supply pipe of the distribution system, and the g21 end of the second water supply pipe of the radiant plate is connected to the fourth water supply pipe of the distribution system. Preferably, the first and third water supply pipes for water distribution are of the same length, and the second and fourth water supply pipes for water distribution are of the same length.

[0011] As a preferred option, both the third and fourth water supply pipes of the water distribution system are equipped with flow meters and electric regulating valves.

[0012] Compared with existing technologies, this invention has the following advantages: The indoor large-space radiant panel ring water pipe system of this invention sets the supply and return water pipes in a "ring," simultaneously supplying water to the same group of radiant panels from two different directions. This reduces the hydraulic imbalance problem within the same group of radiant panels, lowers the temperature difference between panels within the same group, and thus reduces the temperature difference between different groups of radiant panels. Simultaneously, it improves the overall system's energy efficiency ratio, reduces vibration and noise, and simplifies maintenance. Furthermore, since the water supply volume of the first and second water supply pipes for the radiant panels can be reduced to approximately half of the original volume, their pipe diameter can also be reduced compared to existing water supply pipes. Therefore, flow meters and electric regulating valves can be installed on the first and second water supply pipes, respectively, or on the manifold pipes connected to the first and second water supply pipes, thereby controlling the water supply volume of each water supply pipe.

[0017] This utility model provides a ring-shaped water pipe system for indoor large-space radiant panels, used to supply water to a radiant panel device 1 composed of multiple sets of radiant panels, typically supplying water to a radiant panel device 1 with an area exceeding 50㎡. Each set of radiant panels is supplied with water through a radiant panel supply branch pipe 12 and returned through a radiant panel return branch pipe 13. In this embodiment, a heating radiant panel device is taken as an example, such as... Figure 2 As shown in the diagram, the leftmost vertical row of radiant panels is the first group of radiant panels. The others are formed by two adjacent vertical rows of radiant panels per group. The inlet of each radiant panel within each group is connected to the water supply branch pipe 12 of that group, and the outlet is connected to the return branch pipe 13. The radiant panel device 1, composed of multiple groups of radiant panels, is rectangular and suitable for rectangular functional areas, installed at the top of that functional area. Figure 2 As shown, the system includes a first supply and return water pipe group and a second supply and return water pipe group for the radiant panels. The first supply and return water pipe group includes a first supply water pipe 2 and a first return water pipe 3. The first end of each supply water branch pipe 12 is connected to the first supply water pipe 2, and the first end of each return water branch pipe 13 is connected to the first return water pipe 3. Each second supply and return water pipe group includes a second supply water pipe 4 and a second return water pipe 5. The second end of each supply water branch pipe 12 is connected to the second supply water pipe 4, and the second end of each return water branch pipe 13 is connected to the second return water pipe 5. Both the first supply water pipe 2 and the second supply water pipe 4 can supply water to the radiant panels, thus reducing the temperature difference between points A and C, and between points B and D.

[0018] This utility model's indoor large-space radiant panel ring water pipe system sets the supply and return water pipes in a "ring," simultaneously supplying water to the same group of radiant panels from two different directions. This reduces the hydraulic imbalance problem within the same group of radiant panels, lowers the temperature difference between panels within the same group, and thus reduces the temperature difference between different groups of radiant panels. Simultaneously, it improves the overall system's energy efficiency ratio, reduces vibration and noise, and simplifies maintenance. Furthermore, since the water supply volume of the first water supply pipe 2 and the second water supply pipe 4 can be reduced to approximately half of the original volume, their pipe diameter can also be reduced compared to existing water supply pipes. Therefore, flow meters and electric regulating valves can be installed on the first water supply pipe 2 and the second water supply pipe 4, respectively, or on the manifold pipes connected to the first water supply pipe 2 and the second water supply pipe 4, thereby controlling the water supply volume of each water supply pipe.

[0019] like Figure 2 As shown, the connection points of the multiple radiant panel water supply branch pipes 12 to the first radiant panel water supply pipe 2 are sequentially g11, g12...g1n. The direction of water flow in the first radiant panel water supply pipe 2 is from g11 to g1n. The connection points of the multiple radiant panel water supply branch pipes 12 to the second radiant panel water supply pipe 4 are sequentially g21, g22...g2n. The direction of water flow in the second radiant panel water supply pipe 4 is from g2n to g21. That is, the direction of water flow in the second water supply pipe is opposite to the direction of water flow in the first water supply pipe, thus making the hydraulic system more balanced. On the one hand, position B and position A can maintain the same temperature. At the same time, it can also reduce the temperature difference between different groups of radiant panels, so that the rightmost group of radiant panels in the figure has the same temperature as the leftmost group of radiant panels.

[0020] Meanwhile, the connection points of the multiple radiant plate return water branch pipes 13 and the first radiant plate return water pipe 3 are h11, h12...h1n in sequence, and the direction of water flow in the first radiant plate return water pipe 3 is from h1n to h11. The connection points of the multiple radiant plate return water branch pipes 13 and the second radiant plate return water pipe 5 are h21, h22...h2n in sequence, and the direction of water flow in the second radiant plate return water pipe 5 is from h21 to h2n.

[0021] In this embodiment, by adjusting the position of the water distribution manifold 6, the lengths of the first water supply pipe 61 and the second water supply pipe 62 are made approximately the same, resulting in a more balanced water flow and hydraulic equilibrium in the water pipe system. Both the first and second water supply pipes 61 and 62 are equipped with flow meters 9 and electric regulating valves 8. The flow rate of the pipe is obtained through the flow meter 9, and the flow rate is adjusted by the electric regulating valve 8 to maintain it within a set range. This allows for more precise control of the flow rate in each pipe, resulting in a more balanced water flow and further reducing the temperature difference between the radiant panels.

[0022] In this embodiment, as Figure 2 As shown, the g11 end of the first water supply pipe 2 of the radiant plate is connected to the first water supply pipe 61 of the manifold 6, and the g2n end of the second water supply pipe 4 of the radiant plate is connected to the second water supply pipe 62 of the manifold 6. The h11 end of the first return pipe 3 of the radiant plate is connected to the first return pipe 65 of the manifold 6, and the h2n end of the second return pipe 5 of the radiant plate is connected to the second return pipe 66 of the manifold 6.

[0023] The first water supply pipe 2 and the first water return pipe 3 of the radiant panel are connected by a bypass pipe 7, and the second water supply pipe 4 and the second water return pipe 5 of the radiant panel are connected by another bypass pipe 7. The bypass pipe 7 can reduce the temperature difference between the water supply pipe and the water return pipe. At the same time, when the water in the water supply pipe encounters excessive pressure and cannot continue to flow downstream, it can flow into the water return pipe.

[0024] In another embodiment of this utility model, such as Figure 3 As shown, the radiant panel device is composed of multiple sets of radiant panels, making it suitable for larger rooms or functional areas. Figure 3 As shown, the g1n end of the first water supply pipe 2 of the radiant panel is connected to the third water supply pipe 63 of the distribution system, and the g21 end of the second water supply pipe 4 of the radiant panel is connected to the fourth water supply pipe 64 of the distribution system. The h1n end of the first return pipe 3 of the radiant panel is connected to the third return pipe 67 of the distribution system, and the h21 end of the second return pipe 5 of the radiant panel is connected to the fourth return pipe 68 of the distribution system. This ensures that points C and D can reach the same temperature as points A and B, and further reduces the temperature difference among all radiant panels.

[0025] In this embodiment, by adjusting the position of the water distribution manifold 6, the lengths of the first and third water supply pipes 61 and 63 are approximately the same, and the lengths of the second and fourth water supply pipes 62 and 64 are approximately the same. This makes the water flow in the water pipe system more balanced and the hydraulics more hydraulic. In this embodiment, each of the first, second, third, and fourth water supply pipes 61 and 64 is equipped with a flow meter 9 and an electric regulating valve 8. The flow rate of the water pipe is obtained through the flow meter 9, and the flow rate is adjusted by the electric regulating valve 8 to maintain it within a set range. This allows for more precise control of the flow rate of each water pipe, making the water flow more balanced and further reducing the temperature difference between the radiant panels.

[0026] The above embodiments are merely exemplary embodiments of this utility model and are not intended to limit this utility model. The scope of protection of this utility model is defined by the claims. Various modifications or equivalent substitutions made by those skilled in the art within the spirit and scope of this utility model also fall within the scope of protection of this utility model.
