Description

Technical Field

[0001] The present invention relates to a radiation panel for air conditioning that is installed indoors as part of a radiant air conditioning system and performs cooling or heating in a radiation manner by a circulating heat medium.

Background Art

[0002] Conventionally, as a part of a radiant air conditioning system, a radiation panel for air conditioning that performs cooling or heating in a radiation manner by a circulating heat medium includes, for example, the radiation panel for air conditioning described in Patent Document 1.

[0003] The radiation panel for air conditioning having the configuration of Patent Document 1 has a first heat dissipation panel and a second heat dissipation panel in which a plurality of vertical pipes are communicated between upper and lower headers, and the upper and lower headers of both heat dissipation panels are communicated and integrated respectively, and is a resin radiation panel that forms a complicated flow path to control the flow of the heat medium to each pipe. The configuration of the radiation panel for air conditioning of Patent Document 1 will be described with reference to FIG. 10. In the figure, (A) is a left side view, (B) is a front view of the first heat dissipation panel, (C) is a right side view, and (D) is a front view of the second heat dissipation panel. The configuration of Patent Document 1 has a first heat dissipation panel PN1 and a second heat dissipation panel PN2 in which a plurality of vertical pipes are communicated between upper and lower headers H, and the upper and lower headers of both heat dissipation panels are integrated with each other by connecting pipes F, and a complicated flow path is formed to control the flow of the heat medium to each pipe. To explain the flow path example, the water flows from the inlet pipe (101) through the manifold pipe (112), through one vertical pipe (102) of the first heat dissipation panel PN1, into the lower header (103) of the first heat dissipation panel PN1, through multiple vertical pipes (104) into the upper header (105) of the first heat dissipation panel PN1, from this upper header (105) through the connecting pipe (106) into the upper header (107) of the second heat dissipation panel PN2, through one vertical pipe (208) of the second heat dissipation panel PN2 into the lower header (109) of the second heat dissipation panel PN2, through multiple vertical pipes (110) of the second heat dissipation panel PN2 into the upper header (107) of the second heat dissipation panel PN2, through the connecting pipe (111) through the manifold pipe (112), and out through the outlet pipe (113). [Prior art documents]

[0004] [Patent Document 1] Patent No. 5813027 [Overview of the Initiative] [Problems that the invention aims to solve]

[0005] According to the radiant panel for air conditioning described in Patent Document 1, the complex flow path configuration is necessary to improve air venting within the panel and uniform flow distribution to each vertical pipe. This results in complex manufacturing and high costs. Furthermore, there is a problem in that only one vertical pipe passes through each inlet and outlet side of the heat transfer medium, leading to significant pressure loss. Furthermore, when manufacturing heat dissipation panels with different performance levels, it becomes necessary to create a first and second heat dissipation panel with a number of vertical pipes corresponding to each performance level, as well as headers, related components, and flow path formation, which presents the challenge of more complex production management. Furthermore, when offering a lineup of radiant panels with different performance levels, there was the challenge of needing to manufacture and stock many different types of panels, and the need to use multiple panels for locations requiring higher performance. Furthermore, the connection between the header and each vertical pipe is made by resin brazing, but this increases the labor costs and presents a problem of leakage during long-term use. The present invention aims to provide an air conditioning radiant panel that can solve the above problems with a simple configuration. [Means for solving the problem]

[0006] To achieve the above objectives, the present invention provides the following means for solving the problems. The first invention is, The vertical pipes are arranged in two rows, front and back, with the rear row of vertical pipes positioned between the front row of vertical pipes. The system comprises multiple basic panels, each consisting of multiple vertical pipes, an upper header having an upper joint connected to one end of the multiple vertical pipes, an upper flow rate adjustment hole communicating with the upper joint, and an upper external connection for circulating a heat transfer medium with the outside, and a lower header having a lower joint connected to the other end of the multiple vertical pipes, a lower flow rate adjustment hole communicating with the lower joint, and a lower external connection for circulating a heat transfer medium with the outside. Each of the above-mentioned multiple basic panels has an upper external connection part and a lower external connection part. Continued The upper external connection part and the lower external connection part are connected via a seal or through connector attached to the end of the part, and the upper external connection part and the lower external connection part are not attached to the seal or through connector. Continued A sealing plug is attached to the end of the part. The aforementioned multiple sheet The upper header of one of the basic panels is provided with a heat transfer medium inlet pipe connection and an air vent valve connection, and the multiple sheet The other upper header of the basic panel is provided with a heat transfer fluid outlet pipe connection and an air vent valve connection. This radiant panel for air conditioning is characterized by circulating a heat transfer medium introduced from the inlet piping connection through the vertical pipes of the multiple basic panels and leading it out from the outlet piping connection. It is possible to easily connect multiple standardized basic panels as needed using sealing or through connectors to create an air conditioning radiant panel. Both designs efficiently radiate the heat from the vertical pipes in the rear row into the air-conditioned space, thereby improving heating and cooling capacity. Furthermore, since the upper header is equipped with an inlet pipe connection and an air vent valve connection, air can be vented more easily and reliably by connecting to the air vent valve installed in the inlet and outlet piping, and the piping method can be selected according to the installation location, making construction easier.

[0007] The second invention is, In the first invention, the upper joint and the lower joint have insertion holes provided with a water-sealing packing and a retaining ring, and the ends of the vertical pipes are inserted into the insertion holes, characterized in that each vertical The connection points between the pipes and the upper and lower headers are fitted with one-touch connectors, allowing for easy assembly. This eliminates the need for resin brazing or adhesive connections, prevents increased labor costs, and avoids leakage of the heat transfer medium during long-term use. Furthermore, it enables the assembly of radiant panels at the construction site, and height adjustment is possible, improving installation flexibility.

[0008] The 3 The invention relates to an air conditioning radiant panel in which, in either the first or second invention, the inner and outer surfaces of each vertical pipe are made of resin, and an aluminum pipe is inserted between the two resins to form a three-layer aluminum pipe, thereby preventing deterioration of the heat transfer medium due to the permeation of oxygen and other elements from the air, and deformation due to heat during heating, which can occur when the vertical pipes are made of resin. [Effects of the Invention]

[0009] According to the first invention, the following effects can be expected. This is an air conditioning radiant panel with a simple, nearly identical basic panel configuration that can be easily assembled by connecting multiple units as needed. Simple processing and standardization simplify production and inventory management, improve productivity, and allow for smaller manufacturing equipment, thus reducing costs. Since the upper header is equipped with inlet and outlet pipes or air vent valves for the circulating heat transfer medium, these are located above the radiant panel, improving ease of installation and piping work, and allowing for easier and more reliable air venting through the air vent valves installed in the inlet and outlet pipes. • When assembling radiant panels for air conditioning, the upper and lower headers can be easily sealed with sealing plugs, making it easy to offer a lineup of radiant panels with different performance characteristics, as well as to easily respond to load fluctuations after installation. Since there is only one upper and one lower header, the panel depth can be reduced, minimizing the protrusion when mounted on a wall. • By providing flow rate adjustment holes at the connection point between the header and the vertical pipes, the heat transfer medium can be circulated uniformly and simultaneously through each vertical pipe, preventing performance degradation. Each basic panel has multiple vertical pipes connected to a single upper and lower header arranged in two rows, front and back, with the rear vertical pipes positioned between the front vertical pipes. This configuration allows for efficient radiant heat from the rear vertical pipes to be released into the air-conditioned space, improving heating and cooling capacity.

[0010] Furthermore, in the second invention, the upper and lower joints use one-touch fittings that allow for secure connection to the upper and lower headers simply by inserting the vertical pipes, making the vertical pipe connection work extremely easy. Furthermore, 3 In this invention, each vertical pipe is made of three layers of aluminum, with an aluminum pipe in between the inner and outer layers of resin. This eliminates the permeation of oxygen and other elements from the air that occurs in resin pipes, prevents the deterioration of performance over time due to oxidation of the heat transfer medium, and eliminates the need for periodic replacement of the heat transfer medium. Furthermore, because the aluminum three-layer pipe undergoes little expansion and contraction due to heat, deformation of the panel can be prevented even with long-term use.

Mode for Carrying Out the Invention

[0012] Embodiment 1 of the present invention will be described. Figure 1 is an explanatory diagram of Embodiment 1 of the present invention, where (A) is a front view, (B) is a side view, and (C) is a cross-sectional view of the header portion. Note that the connection portion of the lower header 3 to the vertical pipe 1 is the same as the cross-sectional view (C) in Figure 1 and has been omitted. Furthermore, Embodiment 1 and the embodiments described below show a configuration in which the vertical pipe 1 is arranged in two rows, front and back, and the details will be described later in Figure 3. Of course, the vertical pipe 1 may also be arranged in a single row, and the row configuration can be changed as needed. In Figure 1, the first basic panel 5 is an air conditioning radiant panel having a plurality of vertical pipes 1 for circulating a heat transfer medium, an upper header 2 having a joint connected to one end of the plurality of vertical pipes 1 and an upper flow rate adjustment hole 6 communicating with this joint, a lower header 3 having a joint connected to the other end of the plurality of vertical pipes 1 and a lower flow rate adjustment hole 6 communicating with this joint, and external connection parts 4 provided at both ends of the upper header 2 and the lower header 3 for circulating the heat transfer medium to the outside, and circulating the heat transfer medium from one of the upper header 2 or the lower header 3 to the other, via the upper flow rate adjustment hole 6 and the lower flow rate adjustment hole 6 to the plurality of vertical pipes 1 simultaneously. This first basic panel 5 allows heat transfer fluid to flow simultaneously into multiple vertical pipes 1 from the upper header 2 (or lower header 3) and out to the lower header 3 (or upper header 2). The two external connection points 4 of this embodiment 1 are connection points for inlet and outlet piping that allows heat transfer fluid to flow in and out from outside the air conditioning radiant panel. External connection points 4 that do not require connection to the outside can be easily sealed with quick-joint type sealing plugs. Next, an example of the header configuration will be explained in the cross-sectional view of Figure 1(C). Note that the cross-sectional view of Figure 1(C) shows the cross-section of the upper header 2, but the cross-section of the lower header 3 is similar and is therefore omitted. At the joints between the upper header 2 and the lower header 3 and the vertical pipe 1, flow rate adjustment holes 6 with a diameter of approximately 1 / 3 of the inner diameter of the vertical pipe 1 are provided to ensure a uniform flow rate of the heat transfer medium to each vertical pipe 1. In this embodiment, the diameter is approximately 1 / 3 of the inner diameter, but if the diameter is increased, the flow velocity of the heat transfer medium flowing through the vertical pipe will decrease, so the optimal diameter can be designed as needed depending on the situation. With this configuration, the flow rate of the heat transfer medium from the upper header 2 (or lower header 3) to multiple vertical pipes 1 can be adjusted and further distributed simultaneously and evenly. Furthermore, pipe insertion sections 7 are provided in the upper header 2 and the lower header 3. The pipe insertion section 7 is formed in a double-cylindrical shape in cross-section so that the end of the vertical pipe 1 can be inserted. When joining with adhesive, the bonding surface consists of two surfaces, the inner and outer surfaces of the vertical pipe, increasing the bonding area and preventing the adhesive from leaking out. This ensures a secure bond between the vertical pipe and the pipe insertion section 7, preventing the heat transfer medium from leaking out at the connection point with the vertical pipe 1. Embodiment 2 of the Invention

[0013] Embodiment 2 of the present invention will now be described. In the following embodiment of the present invention, the structure of the upper header 2 and the lower header 3 is the same as in Embodiment 1, so their description is omitted. Figure 2 is an explanatory diagram of Embodiment 2 of the present invention, where (A) is a front view and (B) is a side view. In the figure, the second basic panel 8 is an air conditioning radiant panel having a plurality of vertical pipes 1 for circulating a heat transfer medium, an upper header 2 connecting one end of the vertical pipes 1, a lower header 3 connecting the other end of the vertical pipes 1, and external connection parts 4 provided on the upper part of the upper header 2 and on both ends of the upper header 2 and the lower header 3. This air conditioning radiant panel allows the heat transfer medium to flow simultaneously into the plurality of vertical pipes 1 from the upper header 2 (or lower header 3) and flow out to the lower header 3 (or upper header 2). The two upper external connection parts 4a of the upper header 2 are connection parts for inlet and outlet piping or air vent valves for the heat transfer medium. The external connection parts 4 that do not require connection to the outside are connection parts for sealing plugs to prevent leakage. In Embodiment 2, the upper header 2 is provided with an external connection section 4a that allows for easy connection of the heat transfer medium inlet / outlet pipes, air vent valve, and sealing plug using a quick joint type, thereby improving ease of installation and piping work. Furthermore, by connecting the air vent valve provided in the inlet / outlet piping to the external connection section 4a, air venting can be easily and reliably performed. Embodiment 3 of the Invention

[0014] Figure 3 is an explanatory diagram of Embodiment 3 of the present invention, where (A) is a front view, (B) is a side view, and (C) is a cross-sectional view of the front view of (A) from a-a'. In this figure, multiple vertical pipes 1 are arranged in two rows, front and back, and the rear vertical pipe 10 is positioned approximately in the center between the front vertical pipes 9. It is common practice to position the rear vertical pipe 10 behind the front vertical pipes 9 to simplify the header configuration. However, in this embodiment, the radiant heat from the rear vertical pipe 10 is blocked by the front vertical pipes 9, preventing the rear vertical pipe 10 from performing optimally. This reduces the radiant performance of the air conditioning radiant panel relative to the radiant area of ​​the vertical pipes. By positioning the rear vertical pipe 10 approximately in the center between the front vertical pipes 9, as in this embodiment, the radiant performance of the rear vertical pipe 10 is improved, resulting in improved performance of the air conditioning radiant panel. Embodiment 4 of the Invention

[0015] Figure 4 is an explanatory diagram of Embodiment 4 of the present invention, where (A) is a front view and (B) is a cross-sectional view taken along the line b-b' of the front view of (A). In this figure, a row of multiple vertical pipes 11 are connected to an upper header 12 and a lower header 13, and an aluminum panel 14 is provided on the front side of the row of multiple vertical pipes 11, so that at least approximately 50% of the surface area of ​​the vertical pipes 11 is in contact with the aluminum panel 14. The header configuration is the same as in Embodiment 2, with external connection parts 4 at both ends, and can be made into an air conditioning radiant panel by connecting the necessary basic panels. Also, in this figure, the upper header 12 has a connection part 4a at the top for the inlet / outlet piping of the heat transfer medium or an air vent valve, similar to Embodiment 2. Next, the specifications will be explained. The heat transfer medium circulates through the vertical pipes 11, and the surface temperature of the vertical pipes 11 changes. Heat is transferred from the vertical pipe 11 to the aluminum panel 14, changing the temperature of the aluminum panel 14. This significantly increases the surface area of ​​the vertical pipe 11, allowing for radiant heating and cooling through the surface of the aluminum panel 14. This configuration results in a good design, as the vertical pipe 11 is not visible when viewed from the front, and the increased radiant area allows for a smaller air conditioning radiant panel. Furthermore, with the configuration of this embodiment, the upper header 12, the lower header 13, and the vertical pipe 11 can be assembled as a sub-assembly and easily joined to the aluminum panel 14. Embodiment 5 of the Invention

[0016] Embodiment 5 of the present invention will be described. Figure 5 is an explanatory diagram of Embodiment 5 of the present invention, where (A) is a front view and (B) is a side view. It is an assembly diagram of an air conditioning radiant panel in an embodiment in which three first basic panels 5 (5a, 5b, 5c) are connected to slightly increase the capacity. The connection method will be explained below. The upper header 2a of the first basic panel 5a and the upper header 2b of the first basic panel 5b are connected with a quick-joint type sealed connector 15 (hereinafter referred to as a sealed connector) that does not penetrate the interior. The upper header 2b of the first basic panel 5b and the upper header 2c of the first basic panel 5c, the lower header 3a of the first basic panel 5a and the lower header 3b of the first basic panel 5b, and the lower header 3b of the first basic panel 5b and the lower header 3c of the first basic panel 5c are connected with a quick-joint type through connector 16 (hereinafter referred to as a through connector) that penetrates the interior. Furthermore, the inlet piping for the heat transfer medium circulating through the external connection part 4a of the connected upper header 2a is connected to the inlet piping connection part 17, and the outlet piping for the heat transfer medium is connected to the outlet piping connection part 18 of the external connection part 4a of the upper header 2c. In addition, the external connection part 4 of the lower header 3a of panel 5a and the external connection part 4 of the lower header 3c of panel 5c are sealed by connecting a quick-joint type sealing plug 19 (hereinafter referred to as sealing plug) that seals the flow of the heat transfer medium. An air vent valve is provided in the middle of the inlet piping and the outlet piping. Also, if the basic panel designation is a, then the name of each component will also be prefixed with a from now on. For example, if the panel designation is a, the designation for the vertical pipe will be 1a. Let's explain the flow of the heat transfer medium. It flows in from the inlet pipe 17 (arrow ▲1▼), flows from the upper header 2a through multiple vertical pipes 1a to the lower header 3a (arrow ▲2▼), is introduced to the lower headers 3b and 3c through the through connector 16 (arrow ▲3▼), flows through the vertical pipes 1b and 1c (arrow ▲4▼) to the upper headers 2b and 2c, and collects at the heat transfer medium outlet pipe 18 provided in the upper header 2c (arrow ▲5▼) before flowing out (arrow ▲6▼). At this time, the connection between the upper header 2a and the upper header 2b is separated by a sealing connector 15. In this embodiment, air is vented from within the panel because the air vent valve is located in the middle of the heat transfer medium inlet and outlet piping, causing the air to be pushed out by the flow of the heat transfer medium. However, some air may remain inside the panel, which can make the venting process time-consuming. Furthermore, by reversing the header connection configuration, it is possible to change the heat transfer medium inlet and outlet to the lower header. It is also possible to reverse the heat transfer medium inlet and outlet. Embodiment 6 of the Invention Embodiment 6 of the present invention will be described based on the drawings.

[0017] Embodiment 6 of the present invention will now be described. Figure 6 is an explanatory diagram of Embodiment 6 of the present invention, where (A) is a front view and (B) is a side view. It is a diagram of the most commonly used radiant panel assembly for air conditioning, in which two second basic panels 8 (8a, 8b) and one first basic panel 5 (5d) are connected to slightly increase the capacity. The connection method will now be explained. The upper header 2a of the second basic panel 8a and the upper header 2b of the second basic panel 8b are connected by the sealing connector 15, and the upper header 2b of the second basic panel 8b and the upper header 2c of the first basic panel 5d, and the lower header 3a of the second basic panel 8a and the lower header 3b of the second basic panel 8b and the lower header 3c of the first basic panel 5d are connected by the through connector 16. Furthermore, the upper header 2a of the second basic panel 8a is provided with an external connection section 4a for a heat transfer medium inlet pipe connection section 17 and an air vent valve 20, and the upper header 2a of the second basic panel 8b is provided with an outlet pipe connection section 18 and an air vent valve 20. Furthermore, the external connection parts 4 at the non-connected ends of the upper header 2a and lower header 8b of the second basic panel 8a, and the upper header 2d and lower header 3d of the panel 5d, are sealed by connecting the sealing plug 19, which seals the flow of the heat transfer medium. Let's explain the flow of the heat transfer medium. It flows in from the inlet pipe connection 17 (arrow ▲11▼), flows from the upper header 2a through multiple vertical pipes 1a (arrow ▲12▼) into the lower header 3a, is introduced to the lower headers 3b and 3d through the through connector 16 (arrow ▲13▼), flows into the upper headers 2b and 2d through vertical pipes 1b and 1d (arrow ▲14▼), and collects at the heat transfer medium outlet pipe connection 18 provided in the upper header 2b (arrow ▲15▼) before flowing out (arrow ▲16▼). At this time, the connection between the upper header 2a and the upper header 2b is separated by a sealing connector 15. In this embodiment, the inlet and outlet piping for the heat transfer medium can be installed from above, and the air inside the upstream panel 8a of the heat transfer medium can be discharged through an air vent valve 20 provided at the external connection part 4a of the upper header 2a, while the air inside the downstream panels 8b and 5d of the heat transfer medium can be discharged through an air vent valve 20 provided at the external connection part 4a of the upper header 2b, thus enabling easy and reliable air venting. Furthermore, the connections of the sealing connector 15, through connector 16, sealing plug 19, heat transfer medium inlet and outlet piping, and air vent valve 20 are all of the quick-joint type, making installation easier. Furthermore, the positions of panel 8b and panel 5d may be swapped, and the inlet / outlet piping connection and the air vent valve connection may be reversed. Embodiment 7 of the Invention Embodiment 7 of the present invention will be described based on the drawings.

[0018] Figure 7 is an explanatory diagram of Embodiment 7 of the present invention, where (A) is a front view and (B) is a side view. It is an assembly diagram of a high-capacity radiant panel for air conditioning in which one first basic panel 5 (5a) and one second basic panel 8 (8b) are connected on the upstream side of the heat transfer medium, and two first basic panels 5 (5d, 5e) and one basic panel 8 (8c) are connected on the downstream side of the heat transfer medium. Furthermore, the external connection part 4a of the upper header 2b of panel 8b is provided with a heat transfer medium inlet pipe connection part 17 and an air vent valve 20, and the external connection part 4a of the upper header 2c of panel 8c is provided with a heat transfer medium outlet pipe connection part 18 and an air vent valve 20. The connection method will now be explained. Panels 5a and 8b, which are upstream of the heat transfer medium, are connected by a through connector 16, with the upper header 2a and upper header 2b and the lower header 3a and lower header 3b connected to each other. Panels 8c, 5d, and 5e, which are downstream of the heat transfer medium, are connected by a through connector 16, with the upper header 2c, upper header 2d, upper header 2e and the lower header 3c, lower header 3d, and lower header 3e connected to each other. The upper parts of the upper headers 2a and 3c of panels 8b and 8c, which separate the upstream and downstream sides of the heat transfer medium, are connected by a non-through sealing connector 15, and the lower headers 3b and lower header 3c are connected by a through connector 16. The unconnected ends of panels 5a and 5e are sealed by an sealing plug 19 provided on the external connection part 4. Next, the flow of the heat transfer medium will be explained. It flows from the inlet pipe connection 17 into the upper header 2b (arrow ▲21▼), and also flows into the upper header 2a through the through connector 16 (arrow ▲22▼). The incoming heat transfer medium flows through multiple vertical pipes 2a and 2b into the lower headers 3a and 3b (arrow ▲23▼), is introduced into the lower headers 3c, 3d and 3e through the through connector 16 (arrow ▲24▼), flows through multiple vertical pipes 1c, 1d and 1e into the upper headers 2c, 2d and 2e (arrow ▲25▼), and flows out from the heat transfer medium outlet pipe connection 18 provided on the upper header 2c (arrow ▲26▼). At this time, the connection between the upper header 2 and the upper header 2c is separated by a sealing connector 15. The air venting method in this embodiment will now be explained. Air in the upstream panels 5a and 8c of the heat transfer medium can be discharged through the air vent valve 20 on the upper header 2a, and air in the downstream panels 8b, 5d, and 5e of the heat transfer medium can be discharged through the air vent valve 20 provided on the upper header 2b, thus enabling easy and reliable air venting. In addition, the connections of the sealing connector 15, through connector 16, sealing plug 19, heat transfer medium inlet and outlet piping, and air vent valve 20 are all of the quick-joint type, making installation easier. In this embodiment, the basic number of panels is set to five, but in the case of a larger air-conditioned area, the number of basic panels can be increased, which simplifies piping installation and reduces construction costs. Furthermore, although the upper headers 2b and 2c are used as inlets and outlets for the heat transfer medium in this embodiment, the inlet pipe connection 17 and outlet pipe connection 18 may be sealed and referred to as upper headers 2a and 2e. Embodiment 8 of the Invention Embodiment 8 of the present invention will be described based on the drawings.

[0019] Figure 8 is an explanatory diagram of Embodiment 8 of the present invention, and is a partial cross-sectional view in which the header and vertical pipe connection are fitted with a one-touch joint. Here, a partial cross-section of the upper header 2 is shown, but the partial cross-section of the lower header 3 has the same configuration and is therefore omitted. In this embodiment, the upper header 2 and the one-touch joint 21 are integrated. The one-touch joint 21 is designed to be joined simply by inserting the vertical pipe 1. The vertical pipe 1 is inserted through the insertion hole 22 and up to the insertion confirmation hole 23, and then secured with a cap nut 24. At this time, a water-sealing packing 25 prevents leakage of the heat transfer medium, and a retaining ring 26 prevents the vertical pipe 1 from coming loose. In actual operation, the water-sealing packing 25 is inserted into the header, the retaining ring 26 is secured with a cap nut 24 to complete the header, and the vertical pipe 1 is inserted through the insertion hole 22 as needed. Furthermore, to ensure a uniform flow rate of the heat transfer medium to each vertical pipe 1, a flow rate adjustment hole 6 is provided, with a diameter approximately 1 / 3 of the inner diameter of the vertical pipe 1. In this embodiment, the diameter is approximately 1 / 3 of the inner diameter, but increasing the diameter will slow down the flow velocity of the heat transfer medium flowing through the vertical pipe, so the optimal diameter can be designed as needed depending on the situation. This configuration allows for adjustment of the flow rate of the heat transfer medium from the upper header 2 (or lower header 3) to multiple vertical pipes 1, and also enables simultaneous and uniform discharge. Since the connection points between each vertical pipe 1 and the upper header 2 and lower header 3 are made of one-touch joints 21, joining can be done easily and reliably compared to resin brazing or adhesive connections, significantly reducing man-hours and preventing leakage of the heat transfer medium during long-term use. Furthermore, it becomes possible to assemble the radiant panels at the construction site and adjust the height, improving installation flexibility. Embodiment 9 of the Invention Embodiment 9 of the present invention will be described based on the drawings.

[0020] Figure 9 is an explanatory diagram of Embodiment 9 of the present invention, showing a partial view in which the one-touch fittings of the header and vertical pipe connection are detachable. Figure (A) shows the state in which the one-touch fitting is separated from the header, and Figure (B) shows the state in which the header and the one-touch fitting are connected. Here, the two upper header surfaces are shown, but the partial surface of the lower header 3 has the same configuration and is therefore omitted. Also, the internal structure of the one-touch fitting 21 is described in Embodiment 8 and is therefore omitted. The upper header 2 is provided with a flow rate adjustment hole 6 and a female thread 27 that connects to the quick-connect fitting 21. The quick-connect fitting 21 is provided with a male thread 28 that engages with the female thread 27 of the header 2, and the female thread 27 and the male thread 28 are connected by screw fastening. The vertical pipe 1 is assembled by inserting it from the pipe insertion hole 22 to the pipe insertion confirmation hole 23 of the quick-connect fitting 21. In this manner, the one-touch joint connecting the vertical pipe 1 to the header is detachable, which improves molding quality by simplifying the component structure of the header and connection part, and allows for the assembly of the radiant panel at the construction site. Furthermore, the height of the radiant panel can be adjusted by replacing the connection part, thus improving installation flexibility. In this embodiment, the connection between the one-touch joint and the header is made of female and male threads, but a quick-joint type may also be used for simpler assembly.

[0021] As described above, the radiant panel 5 for air conditioning consists of one upper header 2 and one lower header 3, and each basic panel is standardized with a simple configuration. This improves productivity through simple processing, production management, and inventory management, and also allows for smaller manufacturing equipment and lower costs. Furthermore, multiple panels can be easily connected using connectors, and both ends of each header can be easily sealed with connector-type sealing plugs during panel assembly. In addition, the upper header has inlet / outlet piping connection parts and air vent valve connection parts, making piping installation and air venting easier. Moreover, it becomes easier to offer a lineup of radiant panels with different performance characteristics, and it also becomes easier to respond to load fluctuations after installation. Furthermore, since there is only one upper header 2 and one lower header 3, the panel depth is It can be made small, reducing the protrusion when installed on a wall. In addition, the heat transfer medium is circulated through multiple vertical channels. It is a type that can also minimize pressure loss. Furthermore, by arranging multiple vertical pipes 1 in a roughly balanced manner in the front and rear rows, and positioning the rear row vertical pipes approximately in the center between the front row vertical pipes when viewed from the front during installation, the radiant heat from the rear row vertical pipes can be efficiently radiated into the air-conditioned space, thereby improving the heating and cooling capacity. Furthermore, each vertical pipe 1 is constructed as a triple-layered aluminum pipe, with resin on the inner and outer surfaces and an aluminum pipe in between. By using a triple-layered aluminum pipe that does not allow for the permeation of oxygen and other elements from the air, the deterioration of performance over time is prevented, and the replacement of the degrading heat transfer medium becomes unnecessary. In addition, because the triple-layered aluminum pipe undergoes little expansion and contraction due to heat, panel deformation can be prevented even with long-term use. Furthermore, since the connection points between each vertical pipe 1 and the upper header 2 and lower header 3 are made of one-touch joints 21, joining is easier and more reliable compared to resin brazing or adhesive connections, significantly reducing labor costs and preventing leakage of the heat transfer medium during long-term use. In addition, the radiant panels can be assembled at the construction site, and the height can be adjusted, improving installation flexibility. [Industrial applicability]
