[0004] [Patent Document 1] Japanese Patent Publication No. 2025-077096 [Overview of the project] [Problems that the invention aims to solve]

[0005] According to the radiant panel for air conditioning described in Patent Document 1, if the height of the basic panel increases, the length of the vertical pipes also increases, making it difficult to standardize the spacing of the vertical pipes, which reduces strength and makes construction work difficult. Furthermore, when connecting basic panels, it becomes even more difficult to standardize the spacing of the vertical pipes at the connection points. Furthermore, in the radiant air conditioning panel with two basic panels connected together as shown in Figure 9, there is one less vertical pipe in the rear row compared to the front row vertical pipes. This creates a gap of 120 mm on the rear side of the connection point, which is undesirable from a design perspective as it makes the wall visible when the panel is installed against a wall. The purpose of this invention is 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 objective, this invention provides the following means for solving the problem. (1) The first invention relates to a radiant panel for air conditioning, characterized in that it comprises a radiant panel formed by connecting multiple basic panels, each basic panel consisting of a plurality of vertical pipes arranged in two rows, front and back, such that (n-1) rear vertical pipes are arranged between n front vertical pipes; an upper header having an upper joint connected to one end of the plurality of vertical pipes and an upper external connection for connecting to the outside for circulating a heat transfer medium with the outside; and a lower header having a lower joint connected to the other end of the plurality of vertical pipes and a lower external connection for circulating a heat transfer medium with the outside; and a pipe holder that integrally holds the vertical pipes of the radiant panel. (2) The air conditioning radiant panel according to the second invention is characterized in that, in the first invention, the auxiliary vertical pipes, which are held by pipe holders and not connected to the upper and lower headers, are arranged parallel to the rear vertical pipes in the gaps created between the rear vertical pipes of adjacent basic panels. [Effects of the Invention]

[0007] According to this invention, the spacing between the front and rear vertical pipes of the basic panel can be reliably standardized, increasing strength and simplifying construction work. Furthermore, when connecting basic panels, it is easy to standardize the spacing between pipes at the connection points, improving the strength of the connected panels and simplifying construction. Furthermore, according to this invention, by inserting auxiliary vertical pipes into the space created on the rear row side of the connecting portion of the basic panel, the space is eliminated, making the wall invisible when the unit is installed against a wall, thus improving the design. In addition, the auxiliary vertical pipes reach almost the same temperature as the surrounding vertical pipes due to radiant heat, and the radiant heat emitted from these auxiliary vertical pipes also improves heating and cooling performance.

[Modes for carrying out the invention] Hereinafter, embodiments of the present invention will be described based on the drawings. [Examples]

[0009] Embodiments of this invention will be described below. (Overall basic panel configuration) Figure 1 is an explanatory diagram of the basic panel of the present invention, where Figure (A) is a front view thereof, Figure (B) is a cross-sectional view of Figure (A) along the line a-a', and Figure (C) is an enlarged side view of section C of Figure (A). In Figure 1, 1 is a vertical pipe, 2 is an upper header, 3 is a lower header, 4 is an external connection, 5 is a basic panel, 6 is an upper joint, 7 is a lower joint, 8 is a pipe holder, 9 is a front row vertical pipe, and 10 is a rear row vertical pipe. As shown in Figure 1, in the basic panel of this embodiment, multiple vertical pipes 1 are arranged such that a rear row vertical pipe 10 is placed between the row vertical pipes 9. The upper header 2 has an upper joint 6 that connects to one end of the multiple vertical pipes 1, and an upper external connection 4 for circulating a heat transfer medium with the outside. The lower header 3 has a lower joint 7 that connects to the other end of the multiple vertical pipes 1, and a lower external connection 4 for circulating a heat transfer medium with the outside. Pipe holders 8 that integrally hold the multiple vertical pipes 1 are attached to the upper, middle, and lower parts of the vertical pipes 1. (Structure of upper header 2) Figure 2 is a schematic diagram of the upper header 2 (the lower header 3 has the same configuration), with (A) being a front view, (B) a right side view, and (C) a bottom view. In this figure, the same components as in Figure 1 are numbered the same way, with 12 being the vertical pipe insertion section, 13 being the flow rate adjustment hole, and 14 being the heat transfer medium flow passage. As shown in the figure, the heat transfer medium flows from the external connection section 4 into the heat transfer medium flow passage 14, through the flow rate adjustment hole 13, through the connection section 6, and into each vertical pipe 1. (Pipe holder configuration) Figure 3 shows the configuration of the pipe holder 8, with Figure (A) being a top view and Figure (B) being a side view of Figure (A). As is clear from the figure, the pipe holder 8 is provided with seven vertical pipe insertion sections 12 for inserting and fixing the vertical pipes 1, thereby accurately holding the vertical pipes 1. Furthermore, if the pipe holder 8 is made of a spring-like resin, the position of the pipe holder 8 can be freely selected along with installation and removal, allowing for a unified position of the pipe holders as a radiant panel, improving the design, and making it easier to clean the vertical pipes. Furthermore, the number of pipe holders 8 attached to the basic panel 5 is set to three in this embodiment, but this depends on the length of the vertical pipe 1. In other words, if the vertical pipe 1 is short, one is sufficient, but if it is long, three should be used as in this embodiment, and this can be changed as needed. (Configuration of the upper header when two basic panels are connected) Figure 4 is a schematic diagram showing the area around the upper joint 6 of the upper header 2 when two basic panels 5 are connected via an external connection 4. Figure (A) is a front view, and Figure (B) is a bottom view. A space PS equivalent to one vertical pipe 1 is created at the connection point of the rear row vertical pipes 10. This space PS is created at each connection point in proportion to the number of headers 2. Figure 5 is a photograph corresponding to Figure 4, with Figure (A) being a front view and Figure (B) being a bottom view. As is clear from this figure, a space PS equivalent to one vertical pipe 1 is created at the connection point of the rear row vertical pipes 10. (Configuration of the radiant panel when two basic panels are connected) FIG. 6 is a configuration diagram of a radiation panel for air conditioning in a state where two basic panels are connected in series. In the figure, (A) is a front view, (B) is a sectional view taken along the line b-b' of (A), and (C) is a partially enlarged view of the connection portion of the upper header 2. As is clear from the figure, since the plurality of vertical pipes 1 are held and fixed by the high-position holders 8, even when the basic panels 5 are connected in series, the pitch P1 between all the vertical pipes 1 becomes uniform, which has the effect of improving the design and also enhancing the strength of the radiation panel and facilitating construction and the like.

Example

[0010] (Configuration of Radiation Panel with Auxiliary Pipe) As shown in FIGS. 4, 5 and 6, when two basic panels 5 are connected in series, a space PS equivalent to the space of one vertical pipe 1 occurs in the rear row vertical pipe 10. Therefore, in this embodiment, an auxiliary pipe 11 that is not connected to the upper header 6 and the lower header 7 is provided in the space PS so as to be parallel to the vertical pipe 1. FIG. 7 is a diagram showing that state. In the figure, (A) is a diagram showing an intermediate portion between the vertical pipe 1 and the auxiliary pipe 11 of the radiation panel in a state where two basic panels are connected in series, and (B) is a sectional view taken along the line c-c' of the figure. As in this embodiment, by installing the auxiliary vertical pipe 11 in the space PS generated in the rear row vertical pipe 10 at the connection portion of the basic panel 5, when the radiation panel is installed on the wall surface, the wall cannot be seen from the front of the radiation panel, so the design is improved. Further, since the auxiliary vertical pipe 11 is not connected to the upper header 6 and the lower header 7, the heat medium does not flow, but during the heating and cooling operation, the temperature of the auxiliary vertical pipe 11 becomes almost the same as that of the surrounding vertical pipes due to the radiant heat from the surrounding vertical pipes 1, and the heating and cooling performance can be improved by radiating radiant heat from the auxiliary vertical pipe 11 as well. (Fixing of Auxiliary Pipe) Using FIG. 7, the configuration of the pipe holder 8P and the auxiliary vertical pipe 11 will be specifically described. Seven vertical pipes 1 connected to the basic panel 5 are integrally held by the pipe holder 8 to make the intervals between the vertical pipes 1 uniform and to enhance the strength of the basic panel 5. Furthermore, a pipe holder 8P is attached to the connecting portion of the basic panel 5, integrally holding both basic panels 5 together. By integrally holding three vertical pipes 1 from each of the basic panels 5, the spacing of the vertical pipes 1, including the connecting portion of the basic panels 5, is made uniform, and the strength as a radiant panel is increased. In addition, an auxiliary vertical pipe 11 is attached to the pipe insertion portion 12 of the pipe holder 8P. Similar to the pipe holder 8, one to multiple pipe holders 8P are installed depending on the length of the vertical pipes 1. [Industrial applicability]

[0011] As described above, this invention provides an air conditioning radiant panel in which multiple basic panels of nearly identical shape, with rear vertical pipes positioned between front vertical pipes, can be assembled by connecting them as needed. By attaching pipe holders that span both basic panels and hold them integrally to the basic panels and the connecting parts of the basic panels, the spacing between all vertical pipes is unified, the strength of the radiant panel is increased, and construction and other processes are made easier. Furthermore, by installing auxiliary vertical pipes in the space created on the rear side of the basic panel connection, the wall becomes invisible when installed against a wall, improving the design. In addition, although the auxiliary vertical pipes are not connected to the header and therefore no heat transfer medium flows through them, during heating and cooling operation, the temperature of the auxiliary vertical pipes becomes almost the same as that of the surrounding vertical pipes due to radiant heat from the auxiliary vertical pipes, and the radiant heat emitted from the auxiliary vertical pipes also improves heating and cooling performance.
