First, a support leg 10 according to a first embodiment will be described with reference to FIGS. 1(A), 1(B), and 2. FIG. 1(A) is a top perspective view of the support leg 10, and FIG. 1(B) is a bottom perspective view of the support leg 10. FIG. 2 is a side view of the support leg 10 and its surroundings. As shown in FIG. 2, the support legs 10 are typically arranged on a concrete slab 93 of a building (hereinafter simply referred to as "slab 93"), and support the floorboard 91 that constitutes the floor surface of the heating and cooling room R. , which supports a partition plate 92 arranged between a floor plate 91 and a slab 93. The heating and cooling room R is a space (typically a room) that is subjected to cooling or heating (hereinafter referred to as "heating and cooling"). The floorboard 91 is typically made of wood formed into a plate shape. The floorboard 91 may have a single layer structure or a multilayer structure. An example of a multilayer structure is one in which particle board and flooring material are laminated. Furthermore, the floorboard 91 may be made of a material other than wood, and may be made of a metal such as aluminum with a carpet tile provided thereon. The partition plate 92 is typically a foamed resin plate or a wood plate formed into a plate shape. The slab 93 is an example of a structural floor of a building, and may have a structure other than the slab 93. The configuration of the support leg 10 will be explained below.

The support leg 10 mainly includes a support block 11 and an expansion plate 21. The support block 11 has a basic shape of a rectangular parallelepiped, and is formed by performing various processing on the rectangular parallelepiped. Hereinafter, the term "basic shape" refers to the shape before various processing is performed, and in the case of the support block 11, it means the state of a rectangular parallelepiped (square or rectangular on each side of the rectangular parallelepiped, depending on how you look at it). The expansion plate 21 is formed into a plate shape that is thinner than the support block 11 and has a larger outer circumference than the support block 11. In the present embodiment, the support leg 10 includes a support block 11 and an expansion plate 21 that are integrally formed. The support leg 10 is typically a resin molded product, but may be formed by cutting metal, or may be a combination of metal and resin molded product.

In the support block 11, one surface of a basic rectangular parallelepiped is a top surface 12, and the surface on the back side of the top surface 12 is a back surface 13 (see FIG. 1(B)). The support block 11 is used with the top surface 12 facing vertically upward. The top surface 12 is a surface on which the floorboard 91 is placed, as shown in FIG. The top surface 12 of the basic rectangular parallelepiped is formed into a square in this embodiment. In the top surface 12, a screw hole 19 for fixing a floor plate 91 is formed near the centroid of the basic square shape. The support block 11 has a basic shape of a rectangular parallelepiped, and surfaces other than the top surface 12 and the back surface 13 are side surfaces 14. The support block 11 has four side surfaces 14 in its basic rectangular parallelepiped shape. Each side surface 14 intersects with the top surface 12 and the back surface 13, and is perpendicular to the top surface 12 and the back surface 13 in this embodiment in which the basic shape of the support block 11 is a rectangular parallelepiped. In this embodiment, each side surface 14 of the basic rectangular parallelepiped has a length (width) of a side that forms a boundary with the top surface 12 rather than a side length (height) that forms a boundary with an adjacent side surface 14. ) is approximately two to four times longer, and may be approximately three times as long.

The support block 11 has a basic square shape with four corners chamfered in plan view (viewed from the top). The support block 11 has recesses 15 that are one step lower than the top surface 12 at the four chamfered corners. The recess 15 is formed on a diagonal line of the basic square shape of the top surface 12, extending from the apex to a length approximately 0.2 to 0.3 times the length of the diagonal line. The recess 15 is formed even if the centroid side of the square of the basic shape of the top surface 12 (the side far from the apex, hereinafter also referred to as the "end") is rounded (formed in an arc shape). good. A communication hole 16 reaching the back surface 13 is formed at the end of each depression 15 .

The communication hole 16 is a hole for guiding temperature-controlled air (hereinafter referred to as "temperature-controlled air A") existing in the lower space 94 to the upper space 95. Here, the lower space 94 is a space formed between the middle partition plate 92 and the slab 93, and the upper space 95 is a space formed between the floor plate 91 and the middle partition plate 92. The size (diameter) of the communicating hole 16 may be determined by taking into consideration the flow rate of the temperature-controlled air A supplied to the upper space 95. The communication hole 16 communicates the back surface 13 and the depression 15. The communication hole 16 may be formed to have a diameter of 10 mm to 20 mm, for example. In any case, the diameter of the communication hole 16 is shorter than the length from the apex of the basic square shape of the top surface 12 to the end of the depression 15.

In this embodiment, a step surface 17 parallel to the top surface 12 is formed in the recess 15 from the communication hole 16 to the chamfered side surface 14 of the support block 11. Thereby, the depression 15 is formed across the top surface 12 and the side surface 14. In other words, one depression 15 appears on both a part of the top surface 12 and a part of the side surface 14. The depth of the depression 15 (distance from the top surface 12 to the stepped surface 17) is determined by the area of the opening of the depression 15 that appears on the side surface 14 when the floorboard 91 is placed on the top surface 12, and the temperature flowing out from the opening. This is the distance given to the area where the conditioned air A forms a jet. The jet flow referred to here is a phenomenon in which a fluid with velocity is ejected into space from a small hole as a nearly unidirectional flow, typically at a flow rate of approximately 3 m/s to 5 m/s. It is a flow. From this, it can be said that the area of the opening of the depression 15 appearing on the side surface 14 is preferably determined so that the temperature-controlled air A is discharged at a flow rate of approximately 3 m/s to 5 m/s.

In the present embodiment, the support block 11 has a groove 18 formed across the top surface 12 and side surface 14 . The grooves 18 are formed at the midpoints of each side of the basic square shape of the top surface 12 in plan view, and in this embodiment, a total of four grooves 18 are formed. Seen from another perspective, each groove 18 is formed between adjacent depressions 15. The groove 18 is formed to fit a vertical partition plate 29 (see FIG. 3(B)) that partitions the upper space 95, which will be described later. For this purpose, each groove 18 is preferably formed to a size (width, depth, depth) that can appropriately support the vertical partition plate 29, taking into consideration the size and material of the vertical partition plate 29. In this embodiment, the cutout portion as the groove 18 is a rectangular parallelepiped, but this shape may be determined as appropriate depending on the vertical partition plate 29 to be fitted.

The expansion plate 21 is a part that supports the partition plate 92, and extends outward from the lower part of the side surface 14 of the support block 11 (in the direction away from the side surface 14). The expansion plate 21 typically has its back surface (vertically lower surface) flush with the back surface 13 of the support block 11 . The surface (vertically upper surface) of the expansion plate 21 is typically parallel to the top surface 12, and this surface will be referred to as the "intermediate placement surface 22." The intermediate placement surface 22 is a surface on which the intermediate partition plate 92 is placed. The expansion plate 21 may be formed to have a thickness of 1/7 to 1/4, or 1/6 to 1/4, of the thickness of the support block 11 (the distance between the top surface 12 and the back surface 13). It may be formed to have a thickness of 1/5. By forming the expansion plate 21 with such a thickness, the upper space 95 can be secured after the partition plate 92 is placed on the intermediate placement surface 22. The extent to which the expansion plate 21 protrudes from the side surface 14 can be appropriately determined within a range that allows the partition plate 92 to be stably supported. Although the expansion plates 21 are provided over the entire circumference of the side surface 14 in this embodiment, they may be thinned out to the extent that the partition plates 92 can be stably supported.

The support block 11 is provided with a support 25 on the back surface 13. The pillar 25 has a basic cylindrical shape, and a thread is cut on the side surface of the cylindrical shape. The pillar 25 has one cylindrical end surface fixed to the back surface 13. The support column 25 is attached to the centroid position of the back surface 13. The support leg 10 further includes a support post holder 26 . The post support 26 is a member that fits onto the post 25. The strut support 26 is generally formed into a cylindrical shape, and has a female thread cut on the inner surface of the cylindrical shape. The pillar support 26 has a cylindrical shape, and one end surface is closed with a pedestal, and the other end surface is open. The diameter of the pedestal of the post support 26 is larger than the diameter of the cylindrical portion. Since the base of the post support 26 is a portion placed on the slab 93, it is preferably formed in a size that allows it to be placed stably on the slab 93. The strut receiver 26 is configured so that the strut 25 can be rotated and received from the open end surface. By fitting the support 25 and the support 26 with screws, the distance between the support 25 and the support 26, in other words, the distance between the pedestal of the support 26 and the top surface 12 and intermediate mounting surface 22, can be easily adjusted. Can be adjusted.

Next, with reference to FIG. 3(A), a heating and cooling system 100 according to a second embodiment will be described. FIG. 3(A) is a schematic diagram of the heating and cooling system 100. The air conditioning system 100 is a system suitable for heating and cooling the air conditioning room R using radiation. The heating and cooling system 100 includes the above-mentioned support leg 10, the temperature control device 61, the supply duct 63, and the above-mentioned floor plate 91 and partition plate 92 as main components. Since the configurations of the support legs 10, the floor plate 91, and the partition plate 92 have already been explained, the other configurations will be explained here.

The temperature control device 61 is a device that generates temperature-controlled air A in order to cool or heat the floorboard 91 to a temperature suitable for radiant heating and cooling of the cooling/heating room R. Equivalent to. Although a package air conditioner is typically used as the temperature control device 61, an air handling unit, a room air conditioner, or the like may also be used. The temperature control device 61 is arranged outside the heating and cooling room R in this embodiment. In the present embodiment, the heating and cooling system 100 is configured such that the temperature-controlled air A generated by the temperature-control device 61 is guided to the lower space 94 (see FIG. 2) via the supply duct 63. The supply duct 63 is a member that guides the temperature-controlled air A from the temperature-controlled device 61 to the lower space 94. Although a spiral duct is typically used as the supply duct 63, a member capable of conveying the temperature-controlled air A, such as a square duct, a glass wool duct, or a vinyl chloride pipe, can be used as appropriate. Note that the temperature control device 61 may be installed inside the cooling/heating room R, and in this case, if the temperature control air A flowing out from the temperature control device 61 can be directly supplied to the lower space 94, the supply duct 63 can be omitted.

The procedure for constructing the heating and cooling system 100 will be described with reference to FIG. 3(B). FIG. 3(B) is a schematic configuration diagram showing the configuration under the floor of the heating and cooling room R. In the following description, when referring to the structure of the support leg 10 and its surroundings, reference will be made to FIGS. 1(A) and 1(B) and FIG. 2 as appropriate. When constructing the heating and cooling system 100, first, the support legs 10 are arranged on the slab 93. The support legs 10 are arranged in an appropriate number to support the floorboard 91 according to the floor area of the heating/cooling room R. In this embodiment, 5×13 (=65) support legs 10 are arranged at equal intervals vertically and horizontally. The support legs 10 are arranged so that the pedestal of the support post holder 26 contacts the slab 93 and the top surface 12 faces vertically upward. When arranging the support legs 10, the level of the top surface 12 of each support leg 10 placed on the slab 93 is made to be the same by adjusting the degree of screwing of the support support 26 to the support 25.

After the support legs 10 are arranged on the slab 93, the partition plate 92 is placed on the intermediate placement surface 22. In this embodiment, the partition plate 92 has a basic square shape, and the four corners of the square are cut out. Each of the four corner notches of the partition plate 92 corresponds to a shape similar to the basic square shape of the top surface 12 and reduced in area to 1/4. One partition plate 92 is supported by a total of four support legs 10, with one support leg 10 corresponding to each of the four corners. The partition plate 92 is placed so as to fill almost all of the lattice formed by imaginary lines connecting the plurality of support legs 10 vertically and horizontally. Here, the reason why almost all of the grid is filled is because the partition plate 92 is not arranged in the grid corresponding to the position where the supply duct 63 opens (the upper left grid in the example shown in FIG. 3(B)). It is.

After the intermediate partition plates 92 are arranged in each lattice, vertical partition plates 29 are installed along the outer periphery of the plurality of intermediate partition plates 92 arranged as a whole. FIG. 4(A) shows the appearance of the vertical partition plate 29. The vertical partition plate 29 has a shape in which both ends in the longitudinal direction of a square piece are notched so as to fit into the grooves 18. The length (longitudinal distance) of the vertical partition plate 29 corresponds to the distance between the grooves 18 of adjacent support legs 10 among the plurality of support legs 10 arranged. The height of the main portion of the vertical partition plate 29 (portions other than the cutout ends) corresponds to the distance between the intermediate placement surface 22 and the top surface 12. The vertical partition plate 29 may be made of foamed resin or wood.

After installing the vertical partition plate 29, the floor plate 91 is placed on the top surface 12. In this embodiment, the floor plate 91 is formed into a rectangle, and the short sides of the rectangle are supported at both ends by two support legs 10, and the long sides of the rectangle are supported by five support legs 10. That is, in this embodiment, one floorboard 91 is formed into a rectangular shape that is sized to be supported by a total of ten support legs 10. Each support leg 10 to which the vertical partition plate 29 is not attached supports two or four floor plates 91. When the floorboard 91 is placed on the top surface 12, a space surrounded by the floorboard 91, the middle partition plate 92, and the vertical partition plate 29 becomes an upper space 95 (see FIG. 2). Note that the space between the partition plate 92 and the slab 93 is a lower space 94 (see FIG. 2). The situation of the grip around the support leg 10 is shown in FIG. 4(B) for reference. Further, a finishing flooring material may be installed on the plurality of installed floorboards 91 (in the example shown in FIG. 3(A), finishing flooring material is installed).

The floor plate 91 has a hole through which the supply duct 63 passes, which is formed in a portion corresponding to the grid where the partition plate 92 is not installed (the upper left grid in the example shown in FIG. 3(B)), and the supply duct 63 is passed through the hole. A duct 63 is attached. The space on the back side of the floor plate 91 where the supply duct 63 is open communicates with the lower space 94. A reflux port 99 is formed in a portion of the floor plate 91 that corresponds to a diagonal position of the position where the supply duct 63 penetrates when looking at the entire floor plate 91 in which a plurality of floor plates are arranged. The reflux port 99 communicates with the upper space 95 . A grid may be provided in the reflux port 99 from the viewpoint of preventing objects from falling.

Next, the operation of the support legs 10 and the heating and cooling system 100 whose configurations have been described so far will be described. The operation of the support legs 10 will be described as part of the operation of the heating and cooling system 100. In the following description, when referring to the overall configuration of the heating and cooling system 100, reference is mainly made to FIGS. 3(A) and 3(B), and when referring to the configuration around the support legs 10, mainly Please refer to FIGS. 1(A) and 1(B) and FIG. 2. When the operation of the air-conditioning system 100 is started, the temperature control device 61 sets a temperature suitable for radiant cooling and heating of the air-conditioning room R (depending on the set temperature, for example, 18 to 23 degrees Celsius during cooling and 30 to 35 degrees Celsius during heating). ) is generated. Radiant heating and cooling is generally designed to reduce the difference between the temperature of the temperature-controlled air and the outside temperature, compared to heating and cooling that uses only convection (cooling and heating that is performed by supplying temperature-controlled air into the room). Therefore, less energy is required to generate the temperature-controlled air A. Temperature-controlled air A generated by the temperature-controlled device 61 flows into the lower space 94 via the supply duct 63.

The temperature-controlled air A that has flowed into the lower space 94 diffuses throughout the lower space 94 and pressurizes the entire lower space 94. The temperature-controlled air A that diffuses throughout the lower space 94 and pressurizes the lower space 94 flows into the communication hole 16 appearing on the back surface 13 of each support leg 10 and reaches the recess 15 . The temperature-controlled air A that has reached the depression 15 flows through the depression 15 toward the open side surface 14 because the top surface 12 is closed by the floorboard 91. The temperature-controlled air A flowing through the depression 15 flows out into the upper space 95 from the opening on the side surface 14 . At this time, since the opening of the recess 15 on the side surface 14 is formed to have the above-mentioned intended size, the temperature-controlled air A flowing out from the recess 15 becomes a jet and forms a jet on the back surface of the floorboard 91 (air conditioning (the surface opposite to the side of chamber R). When the temperature-controlled air A flows along the back surface of the floorboard 91, the temperature-controlled air A flows while contacting the floorboard 91 and transfers cold heat (during cooling) or warm heat (during heating) to the floorboard 91. This cools or warms the floorboard 91. In addition, since the temperature-controlled air A flows as a jet along the back surface of the floor plate 91, it is possible to destroy the film formed between the temperature-controlled air A and the back surface of the floor plate 91 when the temperature-controlled air A flows. Boundary membranes are extremely thin regions that maintain laminar flow at phase boundaries when fluids are in relative motion. In general, if there is a film where air stays between the floorboard 91 and the flow of temperature-controlled air A, the surface heat transfer resistance increases, and the cold or hot heat held by the temperature-controlled air A is efficiently transferred to the floorboard 91. However, by destroying the membrane, the heat transfer coefficient can be improved.

The outflow of temperature-controlled air A from the above-mentioned depression 15 is typically performed in four directions at intervals of 90 degrees from one support leg 10. Furthermore, in the heating and cooling system 100, a plurality of support legs 10 that support the entire floorboard 91 that constitutes the floor of the heating and cooling room R are arranged at appropriate intervals. Therefore, the cold heat or heat held by the temperature-controlled air A is transmitted almost evenly to the entire floorboard 91 that constitutes the floor of the heating and cooling room R. When cold or warm heat is transferred from the temperature-controlled air A to the floorboard 91 and the floorboard 91 is cooled or warmed, the cold or warm heat is radiated from the cooled or warmed floorboard 91 to the air conditioning room R, thereby cooling the air conditioning room R. Or heating is performed.

The temperature-controlled air A that has transferred cold or warm heat to the floorboard 91 increases in temperature during cooling and decreases during heating. The temperature-controlled air A existing in the upper space 95 after exchanging heat with the floorboard 91 flows into the heating and cooling room R through the recirculation port 99 and convects inside the heating and cooling room R. The temperature-controlled air A flowing into the heating and cooling room R has a temperature equal to or lower than the floorboard 91 during cooling, and a higher temperature than the floorboard 91 during heating, so it contributes to the heating and cooling of the heating and cooling room R. becomes. The temperature-controlled air A that has flowed into the cooling/heating room R flows out to the outside through a door louver (not shown) or the like. Thereafter, the air equivalent to the temperature-controlled air A that has flown out to the outside newly flows into the temperature control device 61, and the temperature-controlled air A whose temperature has been adjusted by the temperature control device 61 is generated. The temperature-controlled air A generated by the temperature-controlled device 61 flows into the lower space 94 via the supply duct 63, and thereafter the above-described operation is repeated.

As explained above, according to the support leg 10 according to the present embodiment, the floor plate 91 and the partition plate 92 can be simultaneously supported with a simple configuration, so that the air conditioning system 100 suitable for radiant air conditioning can be easily installed. can be constructed. Furthermore, since the temperature-controlled air A can be discharged as a jet along the back surface of the floorboard 91 from the opening on the side surface 14 of the recess 15, the cold or warm heat held by the temperature-controlled air A can be efficiently transmitted to the floorboard 91. can be done. Furthermore, according to the air conditioning system 100 according to the present embodiment, the cold or warm heat held by the temperature-controlled air A flowing out from the support leg 10 is efficiently transmitted to the floorboard 91, so that heating and cooling by radiation from the floorboard 91 is efficiently carried out. Can be done effectively.

Note that the jet nozzle 30 shown in FIGS. 5(A) and 5(B) is attached to the recess 15 of the support leg 10 as shown in FIG. 5(C), and the temperature-controlled air A flowing out from the recess 15 is It is also possible to improve the directivity. 5(A) is a perspective view of the jet nozzle 30, FIG. 5(B) is a plan view of the jet nozzle 30, and FIG. 5(C) is a perspective view of the support leg 10 with the jet nozzle 30 attached. The jet nozzle 30 is typically a resin molded product. The jet nozzle 30 includes a cylindrical portion 31 that fits into the communication hole 16, a connecting plate 32 that is placed on the stepped surface 17 of the recess 15, and a bottom plate 33 that extends from the opening of the recess 15 toward the outside of the support block 11. have.

The cylindrical portion 31 is a cylindrical member having a shape and size that fits the communicating hole 16 . In this embodiment, the cylindrical portion 31 is formed into a cylindrical shape having an outer diameter substantially equal to the inner diameter of the communicating hole 16 . The outer diameter of the cylindrical portion 31 is substantially equal to the inner diameter of the communicating hole 16, which means that the cylindrical portion 31 can be attached to and removed from the communicating hole 16 without excessive play, preferably when the cylindrical portion 31 is It is in close contact with the communication hole 16. The cylindrical portion 31 has openings at both end surfaces. The length of the cylindrical portion 31 (the length in the axial direction of the cylindrical shape) may be shorter than the height of the support block 11, as long as it is long enough to stably attach the jet nozzle 30 to the support block 11. The cylindrical portion 31 has a side surface cut out over half of the circumference at one end. The length of this cut side surface (the length in the axial direction of the cylinder) is the same as the depth of the depression 15 (the distance from the top surface 12 to the stepped surface 17). A connecting plate 32 is connected to a semicircular arc portion of the end face of the cylindrical portion 31 that is lowered by one step at the end of the cylindrical portion 31 on the side where the cut side surface is located. The connection plate 32 is a plate-shaped member having substantially the same planar shape as the stepped surface 17 in plan view. The length of the connecting plate 32 that is away from the cylindrical portion 31 (the length in the direction perpendicular to the diameter forming the step at the end of the cylindrical portion 31) may be greater than the length of the stepped surface 17.

The bottom plate 33 is a plate-like member that is generally fan-shaped. The bottom plate 33 is connected to the connection plate 32 at a portion corresponding to the central angle of the sector. The bottom plate 33 is connected to an end of the connecting plate 32 opposite to the end to which the cylindrical portion 31 is connected. The bottom plate 33 is different from a distinct fan shape in that the central angle portion of the fan shape is included in the connecting plate 32, and therefore is expressed as "generally fan-shaped" in the above description. The bottom plate 33 is connected to the connection plate 32 so as to extend on the same plane as the connection plate 32. With this configuration, the bottom plate 33 extends along the back surface of the floor plate 91 toward the outside of the support block 11 when the jet nozzle 30 is attached to the support block 11. The length corresponding to the fan-shaped radius of the bottom plate 33 can be determined as appropriate depending on the flow rate of the temperature-controlled air A, the distance to the adjacent support block 11 to which the jet nozzle 30 is attached, and the like. The length corresponding to the radius of the sector of the bottom plate 33 may be approximately the same as the height of the support block 11, or approximately the same as half the length of one side of the square of the top surface 12, or the length of the diagonal of the square of the top surface 12. It may be about the same length as half. Regarding the temperature-controlled air A flowing out from the recess 15, the bottom plate 33 may have a narrower fan-shaped center angle when placing importance on the reach distance, or may have a wider fan-shaped center angle when placing importance on expanding the supply range. Considering these balances, the central angle of the fan shape of the bottom plate 33 is preferably 120° or less, more preferably 100° or less, from the viewpoint of suppressing the insufficient reach of the temperature-controlled air A. More preferably, the angle is 90° or less. On the other hand, from the viewpoint of suppressing the shortage of the temperature-controlled air A supply range, the angle is preferably 45° or more, more preferably 60° or more, and even more preferably 75° or more.

Side walls 34 are provided on a pair of sides of the connecting plate 32 that connect the cylindrical portion 31 and the bottom plate 33, and on a pair of sides corresponding to the fan-shaped radius of the bottom plate 33. Typically, the side wall 34 is located on the side opposite to the direction in which the cylindrical portion 31 extends (the direction in which the cylindrical portion 31 fitted into the communication hole 16 exists) with respect to the surface of the connection plate 32 and the surface of the bottom plate 33. extends vertically. The height of the side wall 34 is the same as the depth of the recess 15. The side wall 34 has a semicircular portion connected to the side surface of the cylindrical portion 31 where the semicircular portion is not cut out at the end on the side of the cylindrical portion 31 . A rectifying wall 35 is provided on the bottom plate 33 in the direction in which the side wall 34 extends. The rectifying wall 35 is a plate-shaped member having substantially the same height as the side wall 34, and is arranged in a direction that subdivides the central angle of the fan shape of the bottom plate 33. An appropriate number of rectifying walls 35 may be arranged at appropriate intervals, taking into account the size of the central angle of the fan shape of the bottom plate 33, the reach distance of the discharged temperature-controlled air A, and the like. In this embodiment, three rectifying walls 35 are provided at positions that equally divide the fan-shaped center angle of the bottom plate 33 into four. However, for example, for both end portions of the fan shape of the bottom plate 33, the center angle of the fan shape, which is limited by the cooperation of the side wall 34 and the rectifying wall 35 adjacent to the side wall 34, is It may be narrower than the center angle of the fan shape. If the central angle of the fan shape is narrowed, the flow rate of the temperature-controlled air A passing therethrough can be increased, and the distance that the temperature-controlled air A can reach can be extended. Each rectifying wall 35 is not in contact with either the adjacent rectifying wall 35 or the side wall 34, and is independent. The rectifying wall 35 is arranged so as to subdivide the central angle of the fan shape of the bottom plate 33, so the distance between the adjacent rectifying wall 35 or the side wall 34 increases as it progresses from the center side of the fan shape to the circular arc side. ing.

In the jet nozzle 30 configured as described above, as shown in FIG. can be attached to. When a floor plate 91 (see FIG. 2) is installed on the top surface 12 of the support leg 10 having the jet nozzle 30, the upper surface of the jet nozzle 30 is covered by the floor plate 91. As a result, the side wall 34 and the rectifying wall 35 are sandwiched between the bottom plate 33 and the floor plate 91, and the temperature-controlled air A is discharged between the fan-shaped arc portion of the bottom plate 33 and the floor plate 91. It becomes an opening. Note that the entire jet nozzle 30 including the bottom plate 33 is arranged between the floor plate 91 and the partition plate 92. In addition, in the jet nozzle 30 at this time, the bottom plate 33 extends toward the outside of the support block 11 along the back surface of the floor plate 91, and the temperature-controlled air A flowing out from the jet nozzle 30 spreads along the back surface of the floor plate 91. A gap large enough to allow water to flow is provided between the floor plate 91 and the bottom plate 33. In the support leg 10 having the jet nozzle 30, the temperature-controlled air A that has reached the upper space 95 from the lower space 94 (see FIG. 2) through the communication hole 16 is guided to the jet nozzle 30, and then flows to the back surface of the floorboard 91. It will flow along. Therefore, the flow path of the temperature-adjusted air A is restricted and directed by the jet nozzle 30, so that a decrease in flow velocity is suppressed and a deviation in the flow direction is suppressed. As a result, the temperature-controlled air A flowing out from the jet nozzle 30 is supplied to a wide area of the floor plate 91, so that a wide area of the floor plate 91 can be cooled or heated. In addition, in the description here, the planar shape of the bottom plate 33 is generally fan-shaped, but it may be a planar shape other than the fan-shape, such as a triangle.

Next, with reference to FIG. 6, a support member set 1 according to a third embodiment will be described. FIG. 6 is a perspective view of the support member set 1. The support member set 1 includes a plurality of support legs 40 and a connecting member 51 arranged across the two support legs 40. The example shown in FIG. 6 shows the minimum unit of the support member set 1, and in reality, three or more support legs 40 and a plurality of connection members 51 are often provided. The support member set 1, like the support legs 10 shown in FIG. 2, is typically installed on a slab 93 and used so as to support the floor plate 91 and partition plate 92 of the heating and cooling room R. The support member set 1 is used in place of the support legs 10 in the exemplary embodiment shown in FIG. At this time, in the support member set 1, the upper end of the connecting member 51 comes into contact with the back surface of the floorboard 91. In the support member set 1, the support legs 40 are similar to the above-mentioned support legs 10 (see FIG. 1(A)), but there are some differences. Hereinafter, the structure of the support leg 40 and the connecting member 51 will be explained in this order.

7(A) is a top perspective view of the supporting leg 40, and FIG. 7(B) is a plan view of the supporting leg 40. The support leg 40 is different from the support leg 10 (see FIG. 1(A)) in that the configuration and arrangement of the expansion plate 21 and the strut holder 26 are different from those of the support leg 10 (see FIG. 1(A)), including the fact that the upper surface of the expansion plate 21 serves as the intermediate placement surface 22. Same as applicable. Although not shown in the drawings, the structure and arrangement of the struts 25 are also similar to those of the support legs 10. The structure of the support block 41 of the support leg 40 is basically the same as that of the support block 11 (see FIG. 1(A)), but there are differences that will be described later. In the support block 41 of the support leg 40, the top surface 12, back surface 13, side surface 14, and screw hole 19 of the support block 11 (see FIG. 1(A)) are the same as the top surface 42, back surface 43, side surface 44, and screw hole, respectively. Corresponds to 49. In the support block 41, the recess 45 and the communication hole 46 are formed not on the diagonal of the square of the top surface 42, but around the midpoint of a pair of sides of the square of the top surface 42. The support block 41 has no recesses or notches formed at the four chamfered corners of the diagonal line of the square of the top surface 42 and the side surface 44 extending from the diagonal line to the side surface 44. The support block 41 is formed with four recesses similar to the grooves 18 in the support block 11 (see FIG. 1(A)), of which one set (two) facing each other is the groove 48, and the remaining facing One set (two) of the holes is a depression 45. In other words, in the support block 41, depressions 45 and grooves 48 are alternately formed when viewed clockwise in plan view. The groove 48 of the support block 41 has the same structure as the groove 18 (see FIG. 1(A)). The recess 45 of the support block 41 has a similar structure to the groove 48 in appearance, but is different from the groove 48 in that a communication hole 46 reaching the back surface 43 is formed in the step surface 47 inside the recess 45. It is different from The communication hole 46 corresponds to the communication hole 16 (see FIG. 1(A)). Note that the step surface 47 is a surface inside the depression 45 that is parallel to the top surface 42 . The support block 41 has the same structure as the support block 11 (see FIG. 1(A)), including the material, except for the above.

FIG. 8(A) is a perspective view of the connecting member 51. The basic shape of the connecting member 51 is a hollow cylindrical shape with a rectangular cross section and open ends, with one side cut out of the four sides (hereinafter, this cut side will be referred to as "open"). ). In other words, the basic shape of the connecting member 51 is formed into a C-shaped steel (so-called C-shape) shape. Therefore, it can be said that the connecting member 51 is an open channel. In the basic shape of the connecting member 51, a portion corresponding to the side surface facing the opening surface is referred to as a bottom portion 52, and a portion corresponding to both side surfaces orthogonal to the bottom portion 52 is referred to as a side portion 53. The connecting member 51 may be made of resin, or may be made of the same metal as C-shaped steel or another type of metal. The length of the connecting member 51 is typically that of adjacent support legs 10 (see FIG. 3(B)) arranged when constructing the heating and cooling system 100 (see FIG. 3(A)). The length is such that it can be placed in the opposing grooves 18 of the support legs 10. In the connecting member 51, the width of the bottom part 52 is the same as the width of the stepped surface 47 of the recess 45 of the support block 41, and the height of the side part 53 is the same as the depth of the recess 45. The connecting member 51 has through holes 54 formed at both ends of the bottom portion 52 in the longitudinal direction. The through hole 54 is typically formed to have the same shape and size as the communication hole 46 of the support block 41, but may have a shape and size that includes the communication hole 46. In the connecting member 51, notches 55 are formed at predetermined intervals on the side of the side portion 53 that is the boundary with the opening surface (the side opposite to the side connected to the bottom portion 52). The cutout 55 becomes an opening through which the temperature-controlled air A flows out, as shown in FIG. That is, the notch 55 corresponds to the opening of the recess 15 appearing on the side surface 14 of the support leg 10 (see FIG. 1(A)). Therefore, the shape and size of the notch 55 that appear when the opening surface of the connecting member 51 is closed with the floor plate 91 is such that the temperature-controlled air A flowing out from the notch 55 becomes a jet stream. It has a shape and size. Although the shape of the notch 55 is rectangular in this embodiment, it may be an inverted triangle, a semicircle, or any other suitable shape. The predetermined interval for forming the notches 55 is such that when the temperature-controlled air A flowing out from the notch 55 flows along the back surface of the floor plate 91 and the cold or warm heat held by the temperature-controlled air A is transmitted to the floor plate 91. , it is preferable to determine so that the temperature unevenness of the floorboard 91 does not exceed an allowable range. The predetermined interval of the notches 55 may be, for example, 50 mm, 100 mm, 150 mm, 200 mm, or 250 mm. The notches 55 may be arranged such that, in a side view of the connecting member 51, the notches 55 on the other side 53 are located at the midpoint of adjacent notches 55 on one side 53.

The support member set 1 can be used in a heating and cooling system, as described above. Hereinafter, an example will be described in which the support member set 1 is applied in place of the support legs 10 in the heating and cooling system 100 shown in FIG. 3(A). In the following description, in addition to FIG. 6, FIG. 7(A), FIG. 7(B), and FIG. 8(A) showing the support member set 1, reference is also made to FIG. 3(A) and FIG. 3(B) as appropriate. I decided to. Note that when referring to FIGS. 3(A) and 3(B), the supporting legs 10 will be read as supporting legs 40. When constructing a heating and cooling system to which the support member set 1 is applied, first, a plurality of support legs 40 are arranged on the slab 93. The plurality of support legs 40 may be arranged in the same manner as the plurality of support legs 10 are arranged in the heating and cooling system 100. However, when arranging the support legs 40, the directions of the depressions 45 should be aligned. In other words, they are arranged so that the imaginary lines connecting the depressions 45 of each support leg 40 are in a straight line. At this time, it is preferable that the imaginary line connecting the depressions 45 of each support leg 40 extend in the same direction as the long side of the floor of the heating and cooling room R; You can. After the support legs 40 are arranged on the slab 93, the partition plate 92 is placed on the intermediate placement surface 22. This process is the same as when constructing the heating and cooling system 100.

After installing the partition plate 92, the connecting member 51 is placed across the recess 45 of the support leg 40 and the recess 45 of the support leg 40 adjacent to this support leg 40. At this time, the bottom portion 52 is placed on the step surface 47 with the opening surface of the connecting member 51 facing upward. Further, the connecting member 51 is arranged so that the through hole 54 formed in the bottom 52 of the connecting member 51 matches the communication hole 46 formed in the recess 45 of the support leg 40. This arrangement of the connecting member 51 is performed for each support leg 40. FIG. 8(B) shows a state in which the connecting members 51 are arranged on each support leg 40. After the connecting members 51 are arranged on each support leg 40, vertical partition plates 29 are installed along the outer periphery of the plurality of intermediate partition plates 92 arranged as a whole. This process is the same as when constructing the heating and cooling system 100. Note that the vertical partition plate 29 may be installed before or at the same time as the connecting member 51 is placed on each support leg 40. After the connecting member 51 and the vertical partition plate 29 are installed, the floor plate 91 is placed on the top surface 42. This process is the same as when constructing the heating and cooling system 100. When the floor plate 91 is placed on the top surface 42, the opening surface of the connecting member 51 will be closed by the floor plate 91, and the opening of the notch 55 will appear on the side portion 53 of the connecting member 51. The opening of the notch 55 appearing on the side portion 53 of the connecting member 51 becomes a jet port. In this embodiment, the reflux ports 99 installed in the floorboard 91 may be provided in each section sandwiched between the rows of the connecting members 51. For example, when the connecting members 51 are arranged along the longitudinal direction of the rectangular floor of the heating/cooling room R shown in FIGS. 3(A) and 3(B), the connecting members 51 are Since there are four rows of floor plates 91 sandwiched between the vertical partition plate 29 and the vertical partition plate 29, it is preferable to provide four reflux ports 99. This is because, in this embodiment, the upper space 95 is divided by the rows of the connecting members 51. Each reflux port 99 is preferably provided at a position far from the supply duct 63. After the floorboard 91 is installed, the temperature control device 61 and the supply duct 63 are installed as appropriate, thereby creating an air conditioning system to which the support member set 1 is applied.

The operation of the heating and cooling system to which the support member set 1 is applied is as follows. Note that the operation of the support member set 1 and the operation of the support legs 40 will be explained as part of the operation of the air-conditioning system to which the support member set 1 is applied. In the heating and cooling system according to the present embodiment, the operation from the start of operation until the temperature-controlled air A diffuses throughout the lower space 94 and pressurizes the entire lower space 94 is similar to that of the heating and cooling system 100. . In the heating and cooling system to which the support member set 1 according to the present embodiment is applied, the temperature-controlled air A that diffuses throughout the lower space 94 and pressurizes the lower space 94 appears on the back surface 43 of each support leg 40. It flows into the communication hole 46. The temperature-controlled air A flowing into the communication hole 46 passes through the through hole 54 formed in the connecting member 51 arranged in the recess 45, and passes through the space (hereinafter referred to as a space for convenience) surrounded by the connecting member 51 and the back surface of the floorboard 91. (referred to as "inside the connecting member 51"). The temperature-controlled air A that has reached the inside of the connecting member 51 flows inside the connecting member 51 in a direction away from the support leg 40 through which it has passed. Every time the temperature-controlled air A flowing inside the connecting member 51 passes through a notch 55 formed in the side portion 53, it flows out from the inside of the connecting member 51 through the notch 55. . At this time, since the opening of the notch 55 is formed to have the intended size as described above, the temperature-controlled air A flowing out through the notch 55 becomes a jet stream and flows along the back surface of the floorboard 91. flows. Thereafter, when the temperature-controlled air A flows along the back surface of the floorboard 91, the cold or warm heat held by the temperature-controlled air A is efficiently transmitted to the floorboard 91, and the floorboard 91 is cooled or warmed, and the heating and cooling room is heated by radiation. The cooling or heating of R is performed in the same way as in the heating and cooling system 100. In addition, the temperature-controlled air A that has transferred cold or warm heat to the floorboard 91 flows into the air-conditioning room R through the recirculation port 99 and then flows out to the outside. The fact that air newly flows into the temperature control device 61 is also the same as in the heating and cooling system 100. The temperature of the air that has flowed into the temperature control device 61 is adjusted to become temperature controlled air A, which flows into the lower space 94 via the supply duct 63, and thereafter the above-described operation is repeated.

As explained above, the support legs 40 according to the present embodiment can simultaneously support the floor plate 91 and the partition plate 92 with a simple configuration. Further, according to the support member set 1 according to the present embodiment, since the temperature-controlled air A can be discharged as a jet along the back surface of the floorboard 91 from the notch 55, the cold heat held by the temperature-controlled air A can be Heat can be efficiently transferred to the floorboard 91. Moreover, according to the air conditioning system to which the support member set 1 according to the present embodiment is applied, the cold heat or heat held by the temperature-controlled air A flowing out from the support member set 1 is efficiently transmitted to the floorboard 91, so that the floorboard Cooling and heating can be effectively performed by radiation from 91.

Note that, as shown in FIG. 9, by attaching a guide plate 58 to each notch 55, the amount of heat transferred from the temperature-controlled air A flowing out from the notch 55 to the floor plate 91 may be increased. The guide plate 58 is a member whose basic shape is a flat bar. The guide plate 58 has a generally elongated rectangular shape, and the short side of the end connected to the notch 55 is longer than the other portion. The length of the short side of the elongated rectangle in the basic shape of the guide plate 58 is typically shorter than the height of the side portion 53 of the connecting member 51, and is approximately 1/3 to 2/3 of the height of the side portion 53. It may be formed to 1/2. Further, the length of the long side of the elongated rectangle in the basic shape of the guide plate 58 can be determined as appropriate depending on the distance that the temperature-controlled air A flowing out from the notch 55 aims to reach. The length of the long side of the elongated rectangle in the basic shape of the guide plate 58 is, for example, 1/3 to 2/3 or 1/2 of the distance between adjacent notches 55 on one side 53. Good too. The guide plate 58 is typically attached to the notch 55 so that the normal line of the flat bar-shaped surface extends horizontally. Further, in the guide plate 58, the long side of the pair of long sides of the elongated rectangle in the basic shape, which faces the floor plate 91, extends along the back surface of the floor plate 91 while maintaining a predetermined distance from the floor plate 91. It is attached to the notch 55 as shown in FIG. Here, the predetermined distance is a distance at which the Coanda effect occurs in the temperature-controlled air A flowing out from the notch 55. The predetermined distance may be, for example, 2 mm to 5 mm. Note that the long side of the guide plate 58, which extends along the back surface of the floor board 91 while maintaining a predetermined distance from the floor board 91, typically extends parallel to the back surface of the floor board 91. They do not need to be parallel as long as the effect can be produced. By providing the guide plate 58, the temperature-controlled air A flowing out from the notch 55 is attracted to the floor plate 91 due to the Coanda effect, and the flow rate of contact with the floor plate 91 is increased, and the cold or hot heat held by the temperature-controlled air A is increased. can be transmitted to the floorboard 91.

In the above explanation, the gas that cools or heats the floorboard 91 is air (temperature-controlled air A), but any gas other than air may be used as long as it functions as a heat medium that cools or heats the floorboard 91. You can. However, from the viewpoint of ease of handling and availability, it is preferable to use air (temperature-controlled air A) as the gas for cooling or heating the floorboard 91.
