Description

【Technical Field】 【0001】 The present disclosure relates to partition members and air conditioning systems. 【Background Art】 【0002】 In recent years, as an air conditioning method that achieves both energy saving and comfort, a radiant air conditioning system that performs air conditioning by radiant heat has attracted attention. The radiant air conditioning system is a system that cools the ceiling surface, floor surface, etc. during cooling and warms them during heating, and performs air conditioning in the air-conditioned room by radiant heat from the cooled or heated ceiling surface, floor surface, etc. The air conditioning by radiant heat is comfortable because extreme temperature unevenness does not occur indoors, and the amount of heat required to cool or heat the ceiling surface, floor surface, etc. is less than that of a so-called convection-type air conditioning system. Therefore, it can be said that the radiant air conditioning system is a more energy-saving system. 【0003】 The above-described radiant air conditioning system supplies temperature-adjusted air from the space on the back side of the air-conditioned room to the ceiling surface, floor surface, etc. in order to cool or heat the ceiling surface, floor surface, etc. There is the following radiant air conditioning system that can continue radiation even when the supply of temperature-adjusted air to the space on the back side of the air-conditioned room is interrupted. The radiant air conditioning system includes a partition board that partitions the air-conditioned room, and a heat collecting board that is attached to the partition board in the space on the back side of the air-conditioned room and transfers the cold heat or warm heat possessed by the air existing in the back side space to the partition board. The partition board includes a surface plate formed of a material having a specific heat of 650 to 25,000 kJ / m 3 ·K. In this radiant air conditioning system, even when the air flow in the back side space stops, the cold heat or warm heat stored in the surface plate is radiated to the air-conditioned room (see, for example, Patent Document 1). 【Prior Art Documents】 【Patent Documents】 【0004】 【Patent Document 1】 Japanese Patent Application Laid-Open No. 2022-101061 【Summary of the Invention】 [Problems that the invention aims to solve] 【0005】 However, in the radiant heating and cooling system described in Patent Document 1, the heat capacity of the surface plate included in the partition plate is relatively large, so the start-up time is long from the time the equipment for regulating the air temperature is started until cooling or heating is radiated from the partition plate. 【0006】 In view of the above-mentioned problems, this disclosure relates to providing a partition member and a heating and cooling system that shorten the time from startup until the start of radiating cooling or heating to the space to be heated or cooled. [Means for solving the problem] 【0007】 A partitioning member according to a first aspect of the present disclosure comprises a partitioning plate that partitions a space to be cooled or heated, and a plurality of thermal bridge members, each thermal bridge member formed of a material with a higher thermal conductivity than the partitioning plate, the thermal bridge members including a main body integrally formed with a head portion exposed on the surface of the partitioning plate and a shaft portion penetrating the partitioning plate and protruding from the back surface of the partitioning plate. 【0008】 With this configuration, by supplying a temperature-controlled gas to the space behind the partition member, the cold or heat contained in the gas can be transferred to the surface of the partition member via the thermal bridge member, thereby shortening the start-up time for the release of cold or heat from the surface of the partition member. 【0009】 Furthermore, as a partitioning member according to a second aspect of the present disclosure, in the partitioning member according to the first aspect of the present disclosure, the thermal bridging member may further include a nut screwed into the main body on the back side of the partitioning plate, in addition to the main body being composed of a countersunk bolt. 【0010】 With this configuration, the cold or heat contained in the gas present in the space on the back side of the partition member can be transferred to the surface of the partition member with a simple structure. 【0011】 Furthermore, as a partitioning member according to a third aspect of the present disclosure, a partitioning member according to the first or second aspect of the present disclosure may include a backing plate that covers all or part of the back surface of the partitioning plate, and is made of a material with a higher thermal conductivity than the partitioning plate. 【0012】 With this configuration, when a temperature-controlled gas is supplied to the space on the back side of the partition plate, the transfer of cold or heat from the gas to the partition plate can be promoted. 【0013】 Furthermore, as a partitioning member according to a fourth aspect of the present disclosure, a partitioning member according to any one of the first to third aspects of the present disclosure may include a fin attached to the thermal bridge member on the back side of the partitioning plate, the fin extending from the thermal bridge member along the back side of the partitioning plate. 【0014】 This configuration increases the amount of cold or heat transferred from the gas in the space on the back side of the partition plate to the thermal bridge member, and further shortens the time required for the release of cold or heat from the surface of the partition plate to begin. 【0015】 Furthermore, a heating and cooling system according to a fifth aspect of the present disclosure comprises a partition member according to any one of the first to fourth aspects of the present disclosure, and a temperature control device for adjusting the temperature of gas supplied to the space on the back side of the partition plate. 【0016】 With this configuration, the cold or heat contained in the gas is transferred to the partition plate, and heat radiation occurs from the partition plate, thereby enabling cooling or heating of the space to be cooled or heated. 【0017】 Also, as a heating and cooling system according to the sixth aspect of the present disclosure, in the heating and cooling system according to the fifth aspect of the present disclosure, a duct that distributes the gas whose temperature has been adjusted in the temperature control device into the space on the back side of the partition plate, the duct is arranged along the back side surface of the partition member, and an outlet through which the gas flowing inside flows out toward the shaft portion is formed, and the duct may be provided. 【0018】 With such a configuration, the cold heat or warm heat possessed by the gas can be efficiently transmitted to the thermal bridge member. 【Effect of the Invention】 【0019】 According to the present disclosure, by supplying the gas whose temperature has been adjusted to the space on the back side of the partition member, the cold heat or warm heat possessed by the gas can be transmitted to the surface of the partition member via the thermal bridge member, and the start-up time of the release of cold heat or warm heat from the surface of the partition member can be shortened. 【Brief Description of the Drawings】 【0020】 [Figure 1] It is an exploded perspective view of a partition member according to the first embodiment of the present disclosure.

In each figure, members that are the same or corresponding to each other are denoted by the same or similar reference numerals, and duplicate descriptions will be omitted. Also, the dimensions and ratios in the drawings are exaggerated for the convenience of explanation and may differ from the actual ratios. 【0022】 First, referring to FIGS. 1 and 2, the partition member 10 according to the first embodiment of the present disclosure will be described. FIG. 1 is an exploded perspective view of the partition member 10. FIG. 2 is a partial cross-sectional view of the partition member 10. The partition member 10 is a member that partitions a space to be air-conditioned (hereinafter referred to as "air-conditioned space R") where cooling or heating (hereinafter referred to as "air conditioning") is performed. In the present embodiment, it will be described as forming the floor RF of the air-conditioned space R. Since the partition member 10 is typically installed and used on the floor surface BF, which is the surface of the slab forming the structure of the building, hereinafter, for the convenience of explanation, unless otherwise specified, the description will be based on the premise that it is installed on the floor surface BF. The partition member 10 is also a member that obtains cold or heat from the temperature-controlled air (hereinafter referred to as "temperature-controlled air A") supplied to the space S under the floor and radiates the cold or heat. As will be described later, a plurality of partition members 10 are arranged to form the floor RF of the air-conditioned space R. The partition member 10 includes a partition board 11, a back plate 16, and a heat bridge member 20. 【0023】 The partition plate 11 is positioned closest to the heating and cooling room R among the components of the partition member 10, and partitions the heating and cooling room R. In this embodiment, the partition plate 11 is formed in the shape of a square flat plate with sides of 250 mm. However, the partition plate 11 may have sides of 200 mm to 300 mm, or other dimensions (for example, 900 mm x 1800 mm), and its shape is not limited to a square, but may be a rectangle, rhombus, other polygon, or geometric shape. In other words, the shape and size of the partition plate 11 can be appropriately determined according to the shape of the heating and cooling room R and the load-bearing capacity and other conditions under which the partition member 10 is laid. The thickness of the partition plate 11 is generally 10 mm to 30 mm, typically around 20 mm, but may be other dimensions depending on the use of the heating and cooling room R. The partition plate 11 may be formed from a single material, or from multiple layers of the same or different material. The partition plate 11 may be formed, for example, by stacking finishing materials on top of a base material. The material of the partition board 11 may include plywood, particleboard, and / or calcium silicate board, etc. 【0024】 The partition plate 11 has multiple thermal bridge holes 14 through which the thermal bridge members 20 pass. Each thermal bridge hole 14 penetrates in the direction of the thickness of the partition plate 11, that is, from the surface 12 to the back surface 13. In this embodiment, the thermal bridge holes 14 penetrate the centroid of each of the imaginary rectangles that divide the surface 12 into nine equal parts in a 3x3 grid. Thus, nine thermal bridge holes 14 are formed in this embodiment, but the number may be increased or decreased as appropriate depending on the size of the partition plate 11 and its thermal conductivity characteristics. Each thermal bridge hole 14 is formed in a shape and size such that when the thermal bridge member 20 is installed, the top surface of the thermal bridge member 20 and the surface 12 of the partition plate 11 are flush. The partition plate 11 also has fixing holes 15 through which fastening members for fixing to the floor support legs, which will be described later, pass. In this embodiment, a total of four fixing holes 15 are formed at the four corners of the rectangular partition plate 11. Each fixing hole 15, like the thermal bridge holes 14, penetrates in the direction of the thickness of the partition plate 11. 【0025】 The partition plate 11 is typically installed at a distance from the floor surface BF, with its flat surface 12 being horizontal. This creates a space (hereinafter referred to as "underfloor space S") between the floor surface BF and the partition plate 11. The underfloor space S is the space on the back surface 13 of the partition plate 11. The height of the underfloor space S (the distance of the partition plate 11 from the floor surface BF) should be such that it forms a space through which a desired amount of temperature-controlled air A can flow. 【0026】 The backing plate 16 is a member that promotes heat transfer from the temperature-controlled air A supplied to the underfloor space S to the partition plate 11. The backing plate 16 is made of a material with a higher thermal conductivity than the partition plate 11. The backing plate 16 may be made of steel plate or aluminum plate. In this embodiment, the backing plate 16 is formed in a planar shape that is congruent to the back surface 13 so as to cover the entire back surface 13 of the partition plate 11. The thickness of the backing plate 16 can be appropriately determined considering the heat transfer characteristics, as well as strength and weight. For example, it can be 0.4 mm to 1.0 mm, 0.5 mm to 0.8 mm, 0.6 mm, or 1.2 mm or more. The backing plate 16 has through holes 17 through which the thermal bridge member 20 passes, and through holes 18 through which fastening members for fixing the partition plate 11 to the floor support legs, which will be described later, pass. The through holes 17 are formed in positions and sizes corresponding to each thermal bridge hole 14 formed on the back surface 13 when the back plate 16 is superimposed on the back surface 13 of the partition plate 11. The through holes 18 are formed in positions and sizes corresponding to each fixing hole 15 formed on the back surface 13 when the back plate 16 is superimposed on the back surface 13 of the partition plate 11. Each through hole 17 and each through hole 18 penetrates the back plate 16 in the thickness direction. It is preferable that the back surface 13 of the partition plate 11 and the surface of the back plate 16 that is in contact with this back surface 13 be formed as smooth and flat as possible so as to maximize the contact area. 【0027】 The thermal bridge member 20 is a member that guides the cold or heat contained in the temperature-controlled air A supplied to the underfloor space S to the surface 12 side of the partition plate 11 faster than it can be transmitted from the back surface 13 to the front surface 12. The thermal bridge member 20 is made of a material with a higher thermal conductivity than the partition plate 11, and may be made of brass, chromium-molybdenum steel (SCM), steel, stainless steel, etc. In this embodiment, the thermal bridge member 20 includes a main body 21 and a nut 24. In this embodiment, the main body 21 is made of a countersunk bolt and has a head 22 and a shaft 23. The head 22 is formed in the shape of a frustoconical cone. The shaft 23 is formed in the shape of a cylinder and has an external thread on its outer surface. Typically, the main body 21 has the same diameter as the smaller of the frustoconical head 22 and the same diameter as the cylindrical shaft 23. The main body portion 21 has a frustoconical axis of the head portion 22 and a cylindrical axis of the shaft portion 23 located on the same imaginary straight line, and the end face with the smaller diameter of the frustoconical portion is connected to one end face of the cylindrical portion, so that the head portion 22 and the shaft portion 23 are integrally formed. In this embodiment, a flange nut 24 is used and is screw-connected to the shaft portion 23. 【0028】 The thermal bridge member 20 is typically attached to the partition plate 11 and the back plate 16 in the following manner. First, the tip of the shaft portion 23 of the main body portion 21 is inserted into the thermal bridge hole 14 formed in the surface 12. After passing through the thermal bridge hole 14, the shaft portion 23 also passes through the through hole 17 in the back plate 16 and protrudes from the back plate 16 into the underfloor space S. At this point, the main body portion 21 passing through the thermal bridge hole 14 and the through hole 17 stops moving toward the underfloor space S when the end face of the head portion 22 becomes flush with the surface 12. In other words, each thermal bridge hole 14 formed in the partition plate 11 is shaped and sized such that the portion on the surface 12 side, when viewed in the thickness direction, fits the frustocone of the head portion 22. The portion on the back surface 13 side, when viewed in the thickness direction, of each thermal bridge hole 14 is shaped and sized to correspond to a cylindrical inner surface with an inner diameter slightly larger than the outer diameter of the male thread of the shaft portion 23, so that the shaft portion 23 can pass through in a straight line. When the main body 21 is attached to the partition plate 11 and the back plate 16 in this manner, the head portion 22 is exposed on the surface 12 of the partition plate 11. 【0029】 Once the main body 21 is attached to the partition plate 11 and the backing plate 16 in such a manner that the end face of the head 22 is flush with the surface 12, a nut 24 is screwed onto the portion of the shaft 23 that protrudes from the backing plate 16. Typically, the nut 24 is attached with its flange facing the backing plate 16. The nut 24 is screwed in until its flange contacts the backing plate 16. In this way, the nut 24 can press the backing plate 16 against the partition plate 11, preventing the partition plate 11 and the backing plate 16 from separating. The partition plate 11 and the backing plate 16 may be connected via an adhesive (preferably a thermally conductive adhesive with high thermal conductivity). When the nut 24 is screwed onto the shaft 23 and the flange of the nut 24 contacts the backing plate 16, typically the shaft 23 protrudes from the end of the nut 24 opposite to the flange, but the tip of the shaft 23 may be flush with the nut 24 or may not protrude from the nut 24. Furthermore, although only one thermal bridge member 20 is shown in Figure 1 for convenience, in reality, there are as many thermal bridge members 20 as there are thermal bridge holes 14, and each is attached to a respective thermal bridge hole 14. 【0030】 As shown in Figures 3 and 4, the partition member 10 configured as described above is typically laid on the floor surface BF using floor support legs 31. Figure 3 is a perspective view of the partition member 10 from the front side. Figure 4 is a perspective view of the partition member 10 from the back side. The partition member 10 has a front surface on the side facing the heating and cooling room R (in this embodiment, the surface 12 of the partition plate 11) and a back surface on the side facing the underfloor space S (in this embodiment, the surface of the back plate 16). The floor support legs 31 have a lower plate 32, a support rod 33, and an upper plate 34. The lower plate 32 is a plate-shaped member that contacts the floor surface BF and is typically fixed to the floor surface BF using adhesive or anchors. If it is not necessary to fix the lower plate 32 to the floor surface BF, it may be simply placed on the floor surface BF without using adhesive or anchors. The support rod 33 is a member that connects the lower plate 32 and the upper plate 34 while maintaining the distance between them. The length of the support rod 33 affects the height of the underfloor space S. The support rod 33 is mounted perpendicular to the surface of the lower plate 32. The support rod 33 may be configured to allow height adjustment using nuts or long nuts. The upper plate 34 is the member on which the partition members 10 are placed. The upper plate 34 is mounted on the support rod 33 so that its surface is perpendicular to the support rod 33. The upper plate 34 is virtually divided into four equal regions in the front, back, left, and right directions, and one corner of a partition member 10 is placed in one of these regions. Therefore, one upper plate 34 can accommodate the corners of four partition members 10. The upper plate 34 may be fitted with nuts to receive bolts that act as fastening members, passing through the fixing holes 15 and through holes 18 of the partition member 10. These nuts are preferably mounted so as to protrude from the underside of the upper plate 34 (i.e., the side of the lower plate 32). 【0031】 Furthermore, the partition member 10 is typically used with a duct 35 attached. The duct 35 distributes temperature-controlled air A supplied to the underfloor space S to desired locations. In this embodiment, the duct 35 has a lip channel steel 36 and a cushioning material 37. The lip channel steel 36 is positioned so that the lip faces the back surface of the partition member 10. Typically, the lip channel steel 36 is sized to accommodate a nut 24 protruding from the back plate 16 in the opening between a pair of lips extending in the longitudinal direction. Typically, the lip channel steel 36 has a width of about 10 mm per lip and a width of about 40 mm between the pair of lips, but other dimensions may be used. The duct 35 is positioned in the underfloor space S by having the lip channel steel 36 supported by duct support legs 39 installed on the floor surface BF. 【0032】 The cushioning material 37 is a component attached to the outside of the lip channel steel 36, overlapping each lip along its longitudinal direction. One of the purposes of installing the cushioning material 37 is to absorb the deflection of the partition member 10 and prevent floor creaking, and typically rubber or sponge is used. The cushioning material 37 has notches formed at appropriate intervals along its longitudinal direction, and these notches become outlets 38 when the duct 35 is in contact with the back surface of the partition member 10. The outlets 38 are openings through which the temperature-controlled air A inside the duct 35 flows out to the outside of the duct 35, and in this embodiment, they are formed between the partition member 10 and the duct 35. In other words, multiple outlets 38 are provided along the back surface of the partition member 10 (the surface of the back plate 16 in this embodiment). Hereafter, the notches in the cushioning material 37 that become outlets 38 when the duct 35 is brought into contact with the back surface of the partition member 10 are also sometimes referred to as outlets 38, in the sense that they are formed when the duct 35 is brought into contact with the back surface of the partition member 10. Another purpose of installing the cushioning material 37 is to form outlets 38. Multiple outlets 38 are formed in each cushioning material 37. 【0033】 The spacing of the outlets 38 formed in the cushioning material 37 corresponds to the spacing of the nuts 24 (i.e., thermal bridge members 20) in the direction in which the installed duct 35 extends. Furthermore, it is preferable that the size of the outlets 38 be such that the temperature-controlled air A flowing out from the outlets 38 becomes a jet. A jet, in this context, is a phenomenon in which a fluid with velocity is ejected from a small hole into space as a nearly unidirectional flow, and is typically a flow that flows out at a velocity of approximately 3 m / s to 5 m / s. For this reason, it is preferable that the opening area of ​​the outlets 38 be determined according to the flow rate of the temperature-controlled air A flowing inside the duct 35 so that the temperature-controlled air A flows out at a velocity of approximately 3 m / s to 5 m / s. The outlet 38 may have a longitudinal distance of 30 mm to 50 mm, and in this embodiment it is 40 mm. The height (i.e., the distance between the lip of the cushioning material 37 or lip channel steel 36 and the back plate 16 of the partition member 10) may be 5 mm to 10 mm, and in this embodiment it is 7 mm. The detailed arrangement of the duct 35 will be described later. 【0034】 Next, with reference to Figures 5 and 6, a heating and cooling system 1 according to a second embodiment of the present disclosure will be described. Figure 5 is a diagram showing the schematic configuration of the heating and cooling system 1, and shows the room floor RF of the heating and cooling room R in plan view. Figure 6 is a schematic plan view showing the configuration of the underfloor space S in the heating and cooling system 1. Hereafter, when referring to the partition members 10 and the configuration around the partition members 10 in the description of the heating and cooling system 1, Figures 1 to 4 will be referred to as appropriate. In this embodiment, the heating and cooling system 1 comprises a plurality of the partition members 10 described above, the duct 35 mentioned above, an air conditioner 91, and floor panels (described later) for purposes other than those of the partition members 10. In Figure 6, the partition members 10 and other floor panels are shown with dashed lines, and the configuration around the air conditioner 91 is omitted, mainly in order to show the internal structure on the back side of the room floor RF. 【0035】 The air conditioner 91 (see Figure 5) is a device that adjusts the temperature of the air to produce temperature-controlled air A, and is equivalent to a temperature control device. In this embodiment, a packaged air conditioner 91 is used, but a general-purpose room air conditioner may also be used. In this embodiment, the air conditioner 91 is installed on the ceiling of the heating and cooling room R. The air conditioner 91 is connected to a supply duct 92 that guides the generated temperature-controlled air A to the underfloor space S. In addition to the outlet to which the supply duct 92 is connected, the air conditioner 91 may also have an outlet to which a duct (not shown) that directly supplies temperature-controlled air A to the heating and cooling room R is connected. 【0036】 Multiple partition members 10 are arranged vertically and horizontally in a plan view. In the example shown in Figure 5, a total of 24 partition members 10 are arranged in 3 rows x 8 columns, but the number and arrangement can be increased or decreased and changed depending on the size and shape of the heating and cooling room R. For example, the partition members 10 can be arranged in 8 rows, 10 rows, or 12 rows, while keeping the 8 columns constant, or the number of columns can be changed for each row to create an arrangement of 5 columns, 6 columns, or 10 columns, etc. 【0037】 To the right of the partition member 10 in the bottom row of the paper in Figure 5, a duct connection floor 81 is positioned. The duct connection floor 81 is a floor in which connection ports 81H for the supply duct 92 are formed. Typically, the duct connection floor 81 is a partition plate 11 in which connection ports 81H are formed in place of each thermal bridge hole 14, and its size and material are the same as those of the partition plate 11. Floor panels 82 are arranged in two rows above the duct connection floor 81 on the paper (i.e., the same number as the partition members 10 in the row of the duct connection floor 81). Typically, the floor panels 82 are members corresponding to the partition plate 11 in which the backing plate 16 and thermal bridge members 20 are not provided, and each thermal bridge hole 14 is not formed, but a backing plate 16 without through holes 17 may be attached to this member corresponding to the partition plate 11. 【0038】 In Figure 5, a floor with a return port 83 is positioned to the left of the partition member 10 in the top row of the paper. The floor with a return port 83 is a floor in which a return port 83H is formed to move the temperature-controlled air A from the underfloor space S into the heating and cooling room R. Typically, the floor with a return port 83 has return ports 83H formed in place of each thermal bridge hole 14 in the partition plate 11, and its size and material are the same as those of the partition plate 11. Floor panels 84 are arranged in two rows below the floor with a return port 83 (i.e., the same number as the partition members 10 in the row of the floor with a return port 83). The floor panels 84 are the same as the floor panels 82, but are given different designations to distinguish them by their arrangement. 【0039】 The duct connection floor 81, floor panel 82, floor with return port 83, and floor panel 84 are each supported at their four corners by floor support legs 31, and are arranged so that their upper surfaces are flush with the upper surface of the partition member 10. In the example shown in Figure 5, a total of 30 partition members 10, duct connection floor 81, floor panel 82, floor with return port 83, and floor panel 84 are arranged in 3 rows x 10 columns. As shown in Figure 6, floor support legs 31 are positioned on the floor surface BF in the underfloor space S at the positions corresponding to the four corners of each partition member 10, duct connection floor 81, floor panel 82, floor with return port 83, and floor panel 84. 【0040】 As shown in Figure 6, the underfloor space S has the aforementioned ducts 35 arranged in a number corresponding to the number of rows of partition members 10. In the example shown in Figure 5, there are three rows of partition members 10, so in the example shown in Figure 6, there are three ducts 35. The length of each duct 35 corresponds to the length of one row of partition members 10. If the standard length of the lip channel steel 36 that makes up the duct 35 is shorter than the length of one row of partition members 10, multiple lip channel steels 36 are connected to form each duct 35 to a length corresponding to the length of one row of partition members 10. Each duct 35, which is placed in the underfloor space S using duct support legs 39, has a cushioning material 37 attached to the lip channel steel 36 as described above, and an outlet 38 is formed at a predetermined position. The predetermined position is where the thermal bridge member 20 exists on a virtual straight line that is perpendicular to the longitudinal direction of the duct 35 and extends along the back plate 16. Each duct 35 is positioned in a single row of partition member 10 to accommodate the middle row of thermal bridge members 20, of which three rows are arranged. Each row of duct 35 has an end cap 55 attached to its end face on the side of the floor 83 or floor panel 84 with a return port to close the end face. 【0041】 A partition plate 51 is placed in the underfloor space S below the boundary between the row of duct connection floor 81 and floor panel 82 and the adjacent row of partition members 10. The partition plate 51 is a member that separates the underfloor space S below the row of duct connection floor 81 and floor panel 82 from the rest of the underfloor space S. The underfloor space S below the row of duct connection floor 81 and floor panel 82, which is partitioned by the partition plate 51, will be referred to as the "supply underfloor space DS" if it is to be particularly distinguished. The partition plate 51 is in contact with the floor surface BF and the back surfaces of the partition members 10 and / or the duct connection floor 81 and floor panel 82 in the vertical direction. The partition plate 51 is also continuous in the direction in which the row of partition members 10 extends. With this arrangement of the partition plate 51, the supply underfloor space DS is completely partitioned so that the temperature-controlled air A does not directly move to the rest of the underfloor space S. However, the partition plate 51 has inlets 53 formed at the end faces of the ducts 35, connecting the underfloor supply space DS with the inside of the ducts 35. Typically, the number of inlets 53 formed in the partition plate 51 is equal to the number of ducts 35. With this configuration, the temperature-controlled air A in the underfloor supply space DS can flow into the inside of each duct 35 through the inlets 53. A schematic diagram of the partition plate 51 is shown in Figure 7. 【0042】 Next, the operation of the partition member 10 and the heating and cooling system 1 will be explained with reference to Figures 1 to 6. The operation of the partition member 10 will be explained as part of the operation of the heating and cooling system 1. In the heating and cooling system 1, temperature-controlled air A is generated by the air conditioner 91. Temperature-controlled air A is supplied via the supply duct 92 to the supply underfloor space DS directly below the duct connection floor 81. The temperature-controlled air A that flows into the supply underfloor space DS from the supply duct 92 diffuses toward the area directly below the floor panel 82, which is away from the duct connection floor 81. At this time, a portion of the temperature-controlled air A flows into the interior of each duct 35 from each inlet 53. 【0043】 The temperature-controlled air A that flows into the duct 35 from the inlet 53 flows through the inside of the duct 35 toward the end cap 55. The temperature-controlled air A flowing through the inside of the duct 35 toward the end cap 55 flows out to the outside of the duct 35 from each outlet 38. At this time, the temperature-controlled air A flowing out from each outlet 38 flows as a jet along the back surface (i.e., back plate 16) of the partition member 10. By flowing as a jet along the back surface of the partition member 10, the boundary film that forms between the temperature-controlled air A and the back surface of the partition member 10 as it flows can be broken. The boundary film is an extremely thin region that exists at the phase boundary when a fluid is in relative motion, and in which a laminar flow state is maintained. In general, if a boundary film in which air remains between the partition member 10 and the flow of temperature-controlled air A exists, the surface heat transfer resistance increases, and the cold or heat contained in the temperature-controlled air A is not efficiently transferred to the partition member 10. However, the heat transfer coefficient can be improved by breaking the boundary film. 【0044】 As described above, when the temperature-controlled air A flows inside and outside the duct 35, the cold (typically during cooling) or warm (typically during heating) contained in the temperature-controlled air A is transmitted to the partition member 10. Specifically, the temperature-controlled air A flowing inside the duct 35 comes into contact with the back plate 16 and thermal bridge member 20 on the portion facing the flow path inside the duct 35, and the cold or warm is transmitted to the back plate 16 and thermal bridge member 20 in the portion that comes into contact. Furthermore, when the temperature-controlled air A that has flowed out of the duct 35 from each outlet 38 flows along the back surface of the partition member 10, the thermal bridge member 20 is located on a virtual straight line that extends perpendicular to the longitudinal direction of the duct 35, passing through the outlet 38 and along the back plate 16. Therefore, the temperature-controlled air A comes into contact with the back plate 16 and thermal bridge member 20 around this virtual straight line, and the cold or warm is transmitted to the back plate 16 and thermal bridge member 20 in the portion that comes into contact. When the backing plate 16 and thermal bridge member 20 are cooled by the temperature-controlled air A, heat is transferred from the higher-temperature backing plate 16 and thermal bridge member 20 to the lower-temperature temperature-controlled air A. However, for convenience, this is described as the transfer of cooling heat from the temperature-controlled air A to the backing plate 16 and thermal bridge member 20. 【0045】 The compartment member 10 is cooled or heated by the transfer of cold or heat from the temperature-controlled air A described above. Specifically, first, the backing plate 16 and thermal bridge member 20, which are in contact with the temperature-controlled air A, receive cold or heat. In the backing plate 16, which has received cold or heat, the received cold or heat is transmitted to the entire backing plate 16 by heat conduction, and also to the compartment plate 11, which is in contact with the backing plate 16. In the compartment plate 11, which has received cold or heat, the received cold or heat is transmitted from the back surface 13 to the front surface 12 by heat conduction. From the front surface 12 of the cooled or heated compartment plate 11, cold or heat is radiated to the heating and cooling room R, typically via a finishing material (not shown), thereby heating and cooling the heating and cooling room R. On the other hand, in the thermal bridge member 20 that receives cold or heat, the received cold or heat is transmitted by thermal conduction from the nut 24 to the main body 21, and in the main body 21, it is transmitted from the shaft 23 to the head 22. From the surface of the cooled or heated head 22, cold or heat is typically radiated to the air-conditioned room R via a finishing material (not shown), contributing to the heating and cooling of the air-conditioned room R. At this time, since the thermal bridge member 20 has a higher thermal conductivity than the partition plate 11, the radiation of cold or heat to the air-conditioned room R occurs faster from the surface of the head 22 than from the surface 12 of the partition plate 11. In this way, the radiation of the cold or warmth contained in the temperature-controlled air A to the heating and cooling room R occurs via the thermal bridge member 20 before it occurs via the partition plate 11. Therefore, the time required from the start of supplying the temperature-controlled air A until the cold or warmth is radiated from the surface of the partition member 10 (i.e., the start-up time) can be shortened compared to when the thermal bridge member 20 is not provided. 【0046】 The temperature-controlled air A, which has transferred coolness or heat to the partition member 10, rises in temperature during cooling and decreases in temperature during heating, reaching the underfloor space S outside the duct 35. The temperature-controlled air A that reaches the underfloor space S outside the duct 35 moves through the underfloor space S toward the return port 83H and flows into the heating / cooling room R through the return port 83H. In the example shown in Figure 5, one return port 83H is provided, but multiple ports may be provided at appropriate intervals depending on the size of the heating / cooling room R. The temperature-controlled air A that flows into the heating / cooling room R through the return port 83H circulates within the heating / cooling room R. The temperature-controlled air A that flows into the heating / cooling room R is equal to or lower than the temperature of the partition member 10 during cooling and higher than the temperature of the partition member 10 during heating, thus contributing to the heating and cooling of the heating / cooling room R. The temperature-controlled air A that flows into the heating and cooling room R is drawn into the air conditioner 91, where its temperature is adjusted again before being supplied via the supply duct 92 to the supply underfloor space DS beneath the duct connection floor 81, and thereafter the above process is repeated. 【0047】 As described above, the partition member 10 according to the first embodiment of this disclosure and the heating and cooling system 1 according to the second embodiment of this disclosure, which includes the partition member 10, have the following advantages. The partition member 10 includes a plurality of thermal bridge members 20 that have a higher thermal conductivity than the partition plate 11, and each thermal bridge member 20 includes a main body portion 21 which is integrally formed with a head portion 22 exposed on the surface of the partition plate 11 that partitions the heating and cooling room R and a shaft portion 23 that penetrates the partition plate 11 and protrudes from the back surface of the partition plate 11. Therefore, the cold or heat contained in the temperature-controlled air A supplied to the underfloor space S can be transmitted to the surface of the partition member 10 via the thermal bridge members 20, and the start-up time for the radiation (i.e., emission) of cold or heat from the surface of the partition member 10 can be shortened. Furthermore, since the main body 21 of the thermal bridge member 20 is made of countersunk bolts and nuts 24 are screwed into the main body 21 on the back surface 13 of the partition plate 11, the cold or heat contained in the temperature-controlled air A supplied to the underfloor space S can be transmitted to the surface of the partition member 10 with a simple configuration. In addition, since the back plate 16 is connected to the entire back surface 13 of the partition plate 11, the transfer of cold or heat from the temperature-controlled air A to the partition plate 11 can be promoted. Moreover, a duct 35 with multiple outlets 38 is placed on the back surface of the partition member 10, and the temperature-controlled air A flowing out from the outlets 38 is brought into contact with the thermal bridge member 20 protruding from the back plate 16, so that the cold or heat contained in the temperature-controlled air A can be efficiently transmitted to the thermal bridge member 20. 【0048】 Furthermore, fins 25, as shown in the plan view of Figure 8(A) and the side view of Figure 8(B), may be attached to the thermal bridge member 20 located in the underfloor space S, as shown in Figure 8(C). The fins 25 are plate-shaped members that promote the acquisition of cold or heat from the temperature-controlled air A. Typically, the fins 25 are made of a material with a thermal conductivity of the same or greater than that of the thermal bridge member 20, and may be made of the same material as the thermal bridge member 20. In this embodiment, the fins 25 have a basic shape in which a through hole 27 is formed in the center of a plate portion 26 that is generally formed in the shape of a disc, through which the shaft portion 23 of the thermal bridge member 20 passes. Mounting pieces 28 that engage with the threads of the shaft portion 23 are formed around the through hole 27. The mounting pieces 28 are formed as follows. A hole with a diameter smaller than the outer diameter of the shaft portion 23 is formed in the center of the plate portion 26. Cutting lines extending radially from the outer edge of the hole to a circumference with a diameter larger than the outer diameter of the shaft portion 23 are formed at appropriate intervals in the circumferential direction, and the portions between adjacent cutting lines are bent towards the back side of the plate portion 26 to form a mounting piece 28. The hole inside surrounded by this mounting piece 28 becomes the insertion hole 27. In this embodiment, six notches 29 are formed in the plate portion 26 at circumferential intervals, extending radially from outside the mounting piece 28 to the outer edge of the plate portion 26. The formation of the notches 29 reduces the pressure received from the flowing temperature-controlled air A and also allows the leading edge effect to be exerted. The leading edge effect is an effect that can be enjoyed by using the leading edge of the plate portion 26, where heat transfer is good, when temperature-controlled air A flows along the plate portion 26, and a boundary layer is formed on the heat transfer surface (the surface of the plate portion 26) that is thin at the leading edge and increases in thickness downstream. The number of notches 29 is not limited to six; it can be increased or decreased as appropriate, or it may be omitted altogether. Furthermore, the outer shape of the plate portion 26 is not limited to a general circle; it may be elliptical, or a polygon such as a square, hexagon, or octagon. 【0049】 As described above, the fin 25 is attached to the thermal bridge member 20, as shown in Figure 8(C), in a manner in which the mounting piece 28 engages with the threads of the shaft portion 23 protruding from the tip of the nut 24. The fin 25 attached to the thermal bridge member 20 has a plate portion 26 that extends along the backing plate 16 with a gap between it and the backing plate 16. The gap between the plate portion 26 and the backing plate 16 is typically a distance corresponding to the thickness of the nut 24. The fin 25 is typically not attached to thermal bridge members 20 housed inside the duct 35, but to each thermal bridge member 20 or any thermal bridge member 20 located outside the duct 35. In the partition member 10 to which the fin 25 is attached, the temperature-controlled air A that is ejected from the outlet 38 of the duct 35 and flows along the backing plate 16 flows both above and below the plate portion 26 while in contact with the surface of the plate portion 26. When the temperature-controlled air A comes into contact with the fins 25, the cold or heat contained in the temperature-controlled air A is transferred to the fins 25. The cold or heat transferred to the fins 25 is further transferred to the thermal bridge member 20, and as described above, is conducted through the thermal bridge member 20 and radiated from the surface side of the partition member 10. Since the fins 25 have a larger heat transfer area than the thermal bridge member 20 that protrudes from the back plate 16 into the underfloor space S, the transfer of cold or heat from the temperature-controlled air A to the thermal bridge member 20 can be promoted. 【0050】 In the above description, it was assumed that the partition member 10 is equipped with a backing plate 16 that covers the entire back surface of the partition plate 11. However, considering the intended heat transfer mode, the backing plate 16 may cover only a part of the back surface of the partition plate 11, or the backing plate 16 may not be provided at all. If the backing plate 16 is not provided, the outlets 38, which are provided in multiple locations along the back surface of the partition member 10, will be provided along the back surface 13 of the partition plate 11. 【0051】 In the above description, the main body 21 is assumed to be a countersunk bolt, but other materials may be used. In this case, the outer diameter of the head and the shaft may be the same, but it is preferable to increase the outer diameter of the head that is visible on the surface 12 of the partition plate 11, as this increases the radiation area. 【0052】 In the above description, it was assumed that the duct 35 has a lip channel steel 36, but the members forming the flow path for transporting the temperature-controlled air A are not limited to lip channel steel 36, but may be light channel steel or a half-split pipe, etc. Furthermore, in addition to using commercially available materials, thin steel sheets may be bent to any desired dimensions to form lip channel steel, light channel steel, or other shapes. Alternatively, members of underground conduits such as square pipes may be used instead of open channel members, and if underground conduit members are used, it is advisable to form an outlet 38 at an appropriate location. 【0053】 In the above explanation, the partition member 10 was assumed to be installed on the floor surface BF and constitute the room floor RF of the heating and cooling room R, but it may also constitute the wall surface or ceiling surface of the heating and cooling room R. 【0054】 In the above explanation, the temperature control device was assumed to be an air conditioner 91, but any device capable of regulating the temperature of a gas (typically air), such as a fan coil unit, would suffice. 【0055】 While the temperature-controlled gas is assumed to be air (i.e., temperature-controlled air A), other gases may be used depending on the intended use of the heating and cooling room R. However, from the viewpoint of ease of handling, it is preferable to use air as the gas. [Explanation of symbols] 【0056】 1.
