Description

The present invention relates to a gas flow path forming system for heating and cooling and a heating and cooling system, and more particularly to a gas flow path forming system for heating and cooling and a heating and cooling system that suppresses the occurrence of temperature unevenness.

A plurality of large steels are arranged in parallel, and a plurality of joist steels are arranged in parallel on the joist steels so as to intersect with the large steels. There is a steel floor that forms a floor surface by laying (corresponding to a partition member). As a means of heating and cooling the space on the steel floor using such a steel floor, an air flow path is formed inside the large steel and joist steel, and the temperature of the air flow path inside the air flow path has been adjusted. There is a method in which air is flowed, the cold or hot heat of the temperature-controlled air is transmitted to the floor material, and heating and cooling are performed by the radiant heat from the floor material (see, for example, Patent Document 1).

The flow path member system 10 is a system that forms a flow path of the temperature-controlled air A in the backside space S, and corresponds to a gas flow path forming system for heating and cooling. The flow path member system 10 includes a flow path member 11 and support legs 15. The flow path member 11 is a member for forming the flow path 11f (corresponding to the gas flow path) of the temperature-controlled air A so as to extend linearly along the back surface of the floor panel 30, and is a gas flow path forming member. Corresponds to. In the present embodiment, the flow path 11f is formed in an annular shape so as to follow the outer circumference of the square, and a plurality of the flow paths 11f are arranged adjacent to each other like a grid and are adjacent to each other. It is formed so as to share the sides. The term "annular" as used herein means that it is sufficient to connect the linear start point and the end point to make them continuous, and the outer shape thereof is a square as in the present embodiment, a rectangle such as a rectangle, a rhombus, or the like. It may be a polygon such as a quadrangle, a pentagon or a hexagon, or a circle or an ellipse other than the polygon, and is typically shaped to match the contour of the floor panel 30.

In the present embodiment, the flow path 11f is formed exclusively on the same virtual plane, so that the intersecting sides of the flow path 11f are different from those in the case of using the conventional large pull steel and the joist steel. It's different. Further, in the present embodiment, the flow path 11f has a rectangular cross-sectional shape orthogonal to the flow direction of the internal temperature-controlled air A. The flow path member 11 is configured as an open ditch in the present embodiment, and the flow path 11f is formed by closing the open portion with the floor panel 30, in other words, the floor panel 30. The flow path 11f is formed in cooperation with. In the present embodiment, the flow path member 11 has a cross flow path member 12 that constitutes a square corner portion of the basic unit, and a bridge flow path member 13 that constitutes one side portion of the square.

FIG. 4A is a perspective view of the cross flow path member 12. The cross flow path member 12 is a member that forms an intersecting portion of the flow path 11f, and corresponds to a cross flow path forming member. The cross flow path member 12 is formed by combining a bottom plate 12t and a side plate 12s. The bottom plate 12t and the side plate 12s are typically made of a steel plate, but may be made of a resin plate or the like. The bottom plate 12t has a cross shape that remains after cutting out the four corners of the rectangle with small rectangles. The bottom plate 12t has an insertion hole (not shown) through which the support leg 15 is inserted at the center of the cross. The side plate 12s has a rectangular shape, and is provided so as to extend orthogonally to the bottom plate 12t from a portion corresponding to a side of a small rectangle cut out from the large rectangle when forming the bottom plate 12t. .. A total of eight side plates 12s extend in the same direction with respect to the bottom plate 12t. In the cross flow path member 12, the cross flow path height 12h, which is the height of the side plates 12s (the length in the direction orthogonal to the surface of the bottom plate 12t), corresponds to the height of the flow path 11f, and is between the side plates 12s facing each other. The cross flow path width 12w, which is the width of the bottom plate 12t, corresponds to the width of the flow path 11f.

FIG. 4B is a perspective view of the bridge flow path member 13. The bridge flow path member 13 is a member that forms a flow path that connects between the two cross flow path members 12, and corresponds to a bridge flow path forming member. The bridge flow path member 13 has a bottom plate 13t and a side plate 13s. The bridge flow path member 13 is typically made of the same material as the cross flow path member 12, but may be made of a material different from that of the cross flow path member 12. The bottom plate 13t is formed in an elongated rectangle. The side plates 13s are formed in an elongated rectangle, and are provided so as to extend orthogonally to the bottom plate 13t from each of the pair of long sides of the rectangle of the bottom plate 13. A total of two side plates 13s extend in the same direction with respect to the bottom plate 13t. Each side plate 13s is provided with a locking piece 13k at one end in the longitudinal direction. The locking piece 13k extends outward (opposite the flow path 11f) orthogonal to the side plate 13s. The locking piece 13k is formed to have substantially the same size (same or one size smaller) as one of the side sides 12s (see FIG. 4A) of the cross flow path member 12. One locking piece 13k provided on each of the pair of side plates 13s is located diagonally to the rectangle of the bottom plate 13t. In the bridge flow path member 13, the bridge flow path height 13h, which is the height of the side plates 13s (the length in the direction orthogonal to the surface of the bottom plate 13t), corresponds to the height of the flow path 11f, and is between the side plates 13s facing each other. The bridge flow path width 13w, which is the width of the bottom plate 13t, corresponds to the width of the flow path 11f.

Some of the bridge flow path members 13 have an air outlet 13f formed on the side plate 13s. When the open upper part of the bridge flow path member 13 is closed by the floor panel 30 (see FIG. 1), the air outlet 13f uses the temperature-controlled air A inside the flow path 11f as the back surface of the floor panel 30. It is an opening formed for discharging to the outside of the flow path 11f along the flow path 11f, and corresponds to a discharge port. In the present embodiment, the air outlet 13f is formed by being cut out in a semicircular shape on the upper side of the side plate 13s (the long side of the side plate 13s facing the long side in contact with the bottom plate 13t). There are a plurality of air outlets 13f (typically two but three or more) with a distance in the longitudinal direction such that overlapping portions are generated between the temperature-controlled air A discharged from the air outlets 13f adjacent to each other. The temperature-controlled air A discharged from each outlet 13f of a certain set interferes with the temperature-controlled air A discharged from each outlet 13f of a set adjacent to this set while forming one set. It is formed at intervals in the longitudinal direction so as not to prevent it. The position where the air outlet 13f is formed with respect to the entire longitudinal direction of the bridge flow path member 13 will be described later.

FIG. 4C is an exploded perspective view of the support leg 15. Note that FIG. 4C shows the cross flow path member 12 in addition to the constituent members of the support leg 15 in order to explain the positional relationship between the support leg 15 and the cross flow path member 12. The support leg 15 is a member capable of supporting the cross flow path member 12 and supporting the floor panel 30, and corresponds to the support member. The support leg 15 is typically used by being mounted on a floor slab of a building, and has a full screw 16, a rubber 17, a receiving plate 18, and a support plate 19. The full screws 16 have a length from the floor slab to the height at which the floor panel 30 is installed, and are arranged so as to be perpendicular to the floor slab. The rubber 17 is attached to one end of the full screw 16 on the floor slab side and functions as a cushion between the full screw 16 and the floor slab. The receiving plate 18 is a member on which the bottom plate 12t of the cross flow path member 12 is placed, and is formed in the shape of a rectangular plate in the present embodiment. The receiving plate 18 has a hole 18p formed in the central portion through which all the screws 16 can pass, and is supported by the receiving plate nut 185. The receiving plate nut 185 is screwed into all the screws 16 and is located below the receiving plate 18. The height of the receiving plate 18 can be adjusted by adjusting the position of the receiving plate nut 185 with respect to all the screws 16. The cross flow path member 12 is attached to the support leg 15 at the upper part of the receiving plate 18 by inserting all the screws 16 into the insertion holes (not shown) of the cross flow path member 12. The support plate 19 is provided above the cross flow path member 12. The support plate 19 is formed with a hole 19p in the central portion through which all the screws 16 can pass. The support plate 19 is screwed into all the screws 16 and is supported by a support plate nut (not shown) located below the support plate 19. The height of the support plate 19 can be adjusted by adjusting the position of the support plate nut 185 with respect to all the screws 16. By using the full screw 16 in the support leg 15, the height of the cross flow path member 12 and the height of the support plate 19 can be adjusted over the entire length of the full screw 16, respectively. ing.

In order to form the annular flow path member 11 as shown in FIG. 3, the cross flow is formed so that the bottom plate 13t at one end of the bridge flow path member 13 is placed on the bottom plate 12t of the cross flow path member 12. The bridge flow path member 13 is incorporated into the road member 12. Specifically, the locking piece 13k at one end of the bridge flow path member 13 is placed on the bottom plate 12t of the cross flow path member 12, and the cross flow path member 12 sandwiching the bridge flow path member 13 is sandwiched. The side plate 12s connected to the side plate 12s is contacted from the side of the flow path 11f. When this is done for the required portion of the four openings of the cross flow path member 12, an annular flow path 11f along the outer edge of one square as shown in FIG. 3 can be formed. By further expanding this, it is possible to form a net of the flow path 11f that spreads like a grid as shown in FIG. At this time, the interval between the cross flow path members 12, that is, the interval between the support legs 15 is preferably an interval that can stably support the floor panel 30, and the length of the bridge flow path member 13 is adjusted to this interval. You should decide. Alternatively, if there is a portion that is necessary for supporting the floor panel 30 but does not require the bridge flow path member 13, the support leg 15 is provided after omitting the receiving plate 18 and the receiving plate nut 185 from the supporting leg 15. The cross flow path member 12 may not be incorporated in the cross flow path member 12. In the flow path member system 10, a net of a flow path 11f having an arbitrary size can be formed by combining two types of members, the cross flow path member 12 and the bridge flow path member 13, and the network can be generated while simplifying the configuration. Cost can be suppressed. Further, since the basic structure of the bridge flow path member 13 installed between the cross flow path members 12 is common, the width of the flow path 11f becomes uniform in each place, and the difference in pressure loss is suppressed in each place. can do. Further, since the bridge flow path members 13 at various places are incorporated into the four openings at the same height of the cross flow path member 12, the flow path member 11 spreads on the same virtual plane, and this configuration is also possible. It contributes to suppressing the difference in pressure loss in various places.

When the flow path member 11 is installed on the floor slab, the cross flow path member 12 is supported by the support legs 15 at a position floating from the floor slab, so that the entire flow path member 11 is floating from the floor slab. In other words, a space is formed between the entire flow path member 11 and the floor slab. By laying the floor panel 30 in the flow path member system 10 having the flow path member 11 that spreads like a grid as shown in FIG. 2, a fluid such as air is placed between the floor panel 30 and the floor slab. Will be circulated and a backside space S will be formed that functions as an underfloor chamber.

Subsequently, the configuration of the heating / cooling system 100 other than the flow path member system 10 will be described with reference to FIG. 1 mainly and with reference to FIGS. 2 to 4 as appropriate. The partition member 20 is a member for partitioning the back side space S into the supply space SS and the recovery space RS. The supply space SS is a space in which the temperature control air A supplied from the temperature control device 61 is introduced before flowing into the flow path 11f. The recovery space RS is a space in which the temperature-controlled air A discharged from the flow path 11f via the air outlet 13f (see FIG. 4B) in the present embodiment is received. In the present embodiment, the supply space SS is formed in the outer peripheral portion of the entire flow path member 11 that spreads like a grid, and the recovery space RS is formed in the portion inside the supply space SS. The partition member 20 is formed of a plate-shaped member, and is configured so that the upper end when placed on the floor slab is at the same height as the upper surface of the support plate 19 of the support legs 15. The partition member 20 is typically formed by connecting members that are divided into appropriate sizes in the direction in which the surface of the floor slab spreads. The partition member 20 does not enter the inside of the flow path member 11f, and the portion that interferes with the flow path member 11 is cut out so as to avoid the flow path member 11.

Of the four flow paths 11f formed between the side plates 12s facing each other, the bridge flow path member 13 is not incorporated into the outermost cross flow path member 12 arranged in the supply space SS. There is a portion that is an opening, and this opening portion is an inflow port 121 in which the temperature-controlled air A flows into the flow path member 11 from the supply space SS. The inflow port 121 is typically formed in all of the cross flow path members 12 arranged on the outermost side, but an arbitrary opening may be closed to limit the number of inflow ports 121. Regarding the bridge flow path member 13, the above-mentioned outlet 13f is formed on the side plate 13s facing the recovery space RS. The outlet 13f is formed on one side of the center of each bridge flow path member 13 when viewed in the longitudinal direction. In the present embodiment, the recovery space RS is formed from the flow path 11f through the side plate 13s. It is formed on the right side of the center when looking toward. With such a configuration, the temperature-controlled air A discharged from the inside of the flow path 11f to the recovery space RS through the outlet 13f in one bridge flow path member 13 is surrounded by the four bridge flow path members 13 in a plan view. The temperature-controlled air is mainly supplied to a portion of 1/4 of the area of the square recovery space RS, and is discharged from the outlets 13f of the four bridge flow path members 13 constituting the outer edge of the recovery space RS. A will work together to supply the temperature-controlled air A to the entire recovery space RS of one square.

The floor panel 30 partitions the room R and the backside space S as described above, and corresponds to a partition member. The floor panel 30 is typically formed in a rectangular plate shape having a length between adjacent cross flow path members 12 of the flow path members 11 installed on the floor slab as one side length. The floor panel 30 is typically a panel for flooring or raised floor, and may be configured to be divisible into a finishing material and a base material. In the present embodiment, the floor panel 30 is formed to be substantially flat on both the front surface and the back surface. The term "flatness" as used herein is sufficient as long as it is generally recognized as flat as a flooring material, and for example, a case where there is a slight gap appearing at a connecting portion of a plurality of plate materials in a flooring is also included in the flat range. Most of the floor panels 30 constituting the floor surface of the room R are configured to cover the entire floor without openings or the like, but some of them are the supply panel 30p and the recovery panel 30q. Has been exchanged for. The supply panel 30p is formed with an opening to which the duct 63 is connected, and is arranged at a position where the opening communicates with the supply space SS. The recovery panel 30q is formed with a return port 30qh which is an opening capable of guiding the air of the recovery space RS to the room R, and the return port 30qh is arranged at a position where the return port 30qh communicates with the recovery space RS. A grill (lattice) is installed at the return port 30qh of the recovery panel 30q.

The temperature control device 61 is a device that generates temperature control air A adjusted to a temperature at which radiant cooling and heating of the room R can be performed, and corresponds to the temperature control device. As the temperature control device 61, a package type air conditioner is typically used, but an air handling unit, a room air conditioner, or the like may be used. In the present embodiment, the temperature control device 61 is arranged outside the room R, and the temperature control air A generated by the temperature control device 61 is guided to the supply space SS via the duct 63 and the supply panel 30p. It is configured as follows. The temperature control device 61 may be installed in the vicinity of the supply panel 30p in the room R, and at this time, when the temperature control air A flowing out from the temperature control device 61 can be directly supplied to the supply space SS. Does not have to provide the duct 63.

Subsequently, the operations of the flow path member system 10 and the heating / cooling system 100 will be described with reference to FIGS. 1 to 4. In the following, the operation of the flow path member system 10 will be described as a part of the operation of the heating / cooling system 100. The temperature control device 61 generates temperature control air A adjusted to a temperature suitable for radiant cooling and heating of the room R (for example, 18 to 23 ° C during cooling and 30 to 35 ° C during heating, depending on the set temperature). To. Radiant heating and cooling is generally designed so that the difference between the temperature of the temperature-controlled air and the outside air temperature is smaller than that of heating and cooling using only convection (cooling and heating performed by supplying temperature-controlled air to the heating and cooling room). Therefore, less energy is required to generate the temperature-controlled air A. The temperature control air A generated by the temperature control device 61 flows into the supply space SS through the openings of the duct 63 and the supply panel 30p. The temperature-controlled air A that has flowed into the supply space SS from the opening of the supply panel 30p diffuses throughout the supply space SS and flows into the flow path 11f formed inside the flow path member 11 from the inflow port 121. The temperature-controlled air A that has flowed into the flow path 11f from the inflow port 121 has a pressure because the width of each flow path 11f constituting the flow path member 11 that spreads like a grid is uniform and at the same height in each place. Since the difference in loss is suppressed, the diffusion is substantially uniformly spread over the entire flow path 11f of the flow path member 11 that spreads like a grid.

The temperature-controlled air A that has spread throughout the flow path 11f flows out from the outlet 13f and is discharged into the recovery space RS. At this time, since the air outlet 13f is formed on the upper side of the side plate 13s in contact with the floor panel 30, it flows along the back surface of the floor panel 30. In this way, when the temperature-controlled air A flows along the back surface of the floor panel 30, the temperature-controlled air A flows while contacting the floor panel 30, and heats (cools) or heats (heats) to the floor panel 30. introduce. As a result, the floor panel 30 is cooled or warmed. Here, the size of the notch forming the air outlet 13f exists at the boundary film (phase boundary when the fluid is in relative motion) formed between the outflow temperature-controlled air A and the floor panel 30. It is preferable to form an opening area that flows at a wind speed that destroys the ultra-thin region where the laminar flow state is maintained. In general, if there is a boundary film in which air stays between the floor panel 30 and the flow of the temperature-controlled air A, the surface heat transfer resistance becomes large and the cold or hot heat possessed by the temperature-controlled air A is efficiently transferred to the floor panel 30. Although it is not transmitted, the heat transfer coefficient can be improved by destroying the boundary film. Further, since the air outlet 13f is formed so that the temperature-controlled air A discharged from the adjacent ones constituting one set overlap each other, the velocity of the airflow in the overlapping portion increases, and the reach distance The forced heat transfer increases as the temperature is extended, and the amount of heat transferred from the temperature-controlled air A to the floor panel 30 can be increased. When the floor panel 30 is cooled or warmed by the temperature-controlled air A, cold or hot heat is radiated from the cooled or warmed floor panel 30 to the room R, and the room R is cooled or heated.

The temperature of the temperature-controlled air A that has transmitted cold heat or hot heat to the floor panel 30 rises during cooling and decreases during heating. The temperature-controlled air A that exchanges heat with the floor panel 30 and exists in the recovery space RS flows into the room R through the return port 30qh formed in the recovery panel 30q and convects in the room R. The temperature-controlled air A that has flowed into the room R is equal to the temperature of the floor panel 30, or is lower than the floor panel 30 during cooling and higher than the floor panel 30 during heating, and thus contributes to the cooling and heating of the room R. It will be. The temperature-controlled air A that has flowed into the room R through the return port 30qh then flows out from a door garage (not shown) or the like. The temperature-controlled air A that has flowed out to the outside flows into the supply space SS from the temperature-controlled device 61 through the openings of the duct 63 and the supply panel 30p, and thereafter repeats the above-mentioned operation.

As described above, according to the heating / cooling system according to the present embodiment, the flow path 11f of the flow path member system 10 according to the present embodiment, which is one of the elements constituting the heating / cooling system, is square. Since the rings formed in a row spread like a grid and the widths of each part are uniform and at the same height, the floor changes in temperature due to heat transfer from the temperature-controlled air A discharged from the outlet 13f. It is possible to suppress the occurrence of temperature unevenness on the panel 30, and it is possible to perform substantially uniform heating and cooling of the room R. Further, the flow path member 11 has a simple structure because the cross flow path member 12 and the bridge flow path member 13 which are the constituent members are basically formed of common members and are configured by combining them. It is possible to suppress the generation cost while keeping it.

Next, the bridge flow path member 13A according to the modified example will be described with reference to FIG. FIG. 5A is a partial perspective view of the bridge flow path member 13A, showing a part of the side plate 13s. In the bridge flow path member 13A, instead of the air outlet 13f (see FIG. 4B) formed in the side plate 13s in a semicircular shape in the above-mentioned bridge flow path member 13 (see FIG. 4B), the bridge flow path member 13A is connected. A part 70 is provided. The connecting portion 70 includes a connecting hole 71 formed by cutting out a rectangular shape from the upper side of the side plate 13s toward the bottom plate 13t. In the present embodiment, the connecting hole 71 does not reach the bottom plate 13t, and is cut to a depth of approximately 1/2 to 2/3 of the bridge flow path height 13h. Connecting guides 72 are formed on both the left and right sides of the connecting hole 71 (on both sides of the bridge flow path member 13A in the longitudinal direction). The connecting guide 72 is a slit (elongated notch) for attaching a component described later to the connecting portion 70. The connecting guide 72 is formed at the same depth as the connecting hole 71. The connecting portion 70 is 1 in FIG. 5 (A) because one set of outlets 13f formed in the bridge flow path member 13 (see FIG. 4 (B)) described above corresponds to one of the connecting portions 70. Although only one connecting portion 70 is shown, typically, the same number of connecting portions 70 as the number of pairs of outlets 13f formed in the bridge flow path member 13 (see FIG. 4B) are the bridge flow path. It is formed on the member 13A.

FIG. 5B is a perspective view of the oblique nozzle 73, which is an example of a component attached to the connecting portion 70. The oblique nozzle 73 has a closing plate 73c including a nozzle portion 73n and a rail 73r. The closing plate 73c is formed to have substantially the same size as the connecting hole 71 so that the connecting hole 71 is closed when the oblique nozzle 73 is attached to the connecting portion 70. The nozzle portion 73n provided on the closing plate 73c is composed of a pair of side plates 73e surrounding a rectangular opening formed by cutting the closing plate 73c and one swash plate 73s. The pair of side plates 73e are parallel to the left and right sides of the closing plate 73c and extend orthogonal to the plane of the closing plate 73c. The swash plate 73s is provided below the space between the pair of side plates 73e. The nozzle portion 73n typically forms a pair of cuts extending vertically downward from the upper side of a rectangular thin plate at intervals in the horizontal direction, and connects the lower ends of the pair of cuts with each other. The portion sandwiched between the notches is bent outward (for example, at 30 ° or 45 °), the bent portion is used as the swash plate 73s, and the closing plate 73c and the swash plate 73c generated by bending the swash plate 73s. It is configured in a manner in which a pair of side plates 73e are attached so as to close the gap between the two. The nozzle portion 73n configured in this way is formed so that the opening area of the cross section becomes smaller as it advances from the side of the closing plate 73c to the side of the tip, and the discharge port is located at the farthest portion from the closing plate 73c. 73p is formed. The discharge port 73p corresponds to the discharge port. With this configuration, the gas discharged from the discharge port 73p of the nozzle portion 73n is configured to be a jet stream. The rail 73r is an elongated member having an L-shaped cross section, and is provided on both the left and right sides of the closing plate 73c. The distance between the pair of rails 73r provided on the left and right sides of the closing plate 73c is equal to the distance between the pair of connecting guides 72 provided in the connecting portion 70. In the description of the oblique nozzle 73 here, for convenience, the closing plate 73c and the rail 73r are described separately, but typically, one thin plate is bent and integrally formed. The gap formed between the rail 73r and the closing plate 73c is substantially the same as the thickness of the side plate 13s of the bridge flow path member 13A. In order to attach the oblique nozzle 73 to the connecting portion 70, the side of the closing plate 73c opposite to the side on which the discharge port 73p is formed is arranged so as to face the upper side of the side plate 13s of the bridge flow path member 13A. , The pair of rails 73r is fitted into the pair of slits of the connecting guide 72, and the oblique nozzle 73 is brought closer to the bottom plate 13t.

FIG. 5C is a perspective view of a two-way nozzle 75A, which is another example of a component attached to the connecting portion 70. The two-way nozzle 75A has a closing plate 75c including a nozzle portion 75n and a rail 75r. Compared with the oblique nozzle 73 (see FIG. 5 (B)), the two-way nozzle 75A has a half-split shape in place of the nozzle portion 73n (see FIG. 5 (B)) provided in the oblique nozzle 73. The difference is that the nozzle portion 75n having a plurality of short tubes is provided. Therefore, the closing plate 75c of the two-way nozzle 75A corresponds to the closing plate 73c of the oblique nozzle 73, and the rail 75r of the two-way nozzle 75A has the same configuration as the rail 73r of the oblique nozzle 73. The closing plate 75c of the two-way nozzle 75A has a semicircular notch formed on the upper side similar to the outlet 13f (see FIG. 4B), and the notch is perpendicular to the surface of the closing plate 75c. A semicircular short tube is attached so as to extend. The tip of this half-split short tube corresponds to the outlet. The two-way nozzle 75A configured in this way is attached to the bridge flow path member 13A in the same manner as the oblique nozzle 73 (see FIG. 5B). In the bridge flow path member 13A to which the two-way nozzle 75A is attached, the temperature-controlled air A flowing out from the flow path 11f toward the recovery space RS is collected after the flow path is restricted by the half-split pipe of the nozzle portion 75n. Since the air flows out to the RS, the directivity is increased and the reach is longer than that of the temperature-controlled air A discharged from the outlet 13f, so that efficient heating and cooling can be performed.

FIG. 5D is a perspective view of a three-way nozzle 75B, which is still another example of a component attached to the connecting portion 70. The three-way nozzle 75B is different from the two-way nozzle 75A in that, in addition to the configuration of the two-way nozzle 75A (see FIG. 5C), an oblique tube 75s is added below the nozzle portion 75n. The oblique pipe 75s is composed of a short pipe having a diameter similar to that of the half-split pipe constituting the nozzle portion 75n, and the closing plate approaches the half-split pipe of the nozzle portion 75n as the distance from the closing plate 75c increases. It is mounted diagonally to the 75c surface. The oblique pipe 75s is tilted at an angle of about 30 ° to 45 ° with respect to the closing plate 75c. In the three-way nozzle 75B, the tip of the oblique tube 75s corresponds to the discharge port in addition to the tip of the half-split short tube. The three-way nozzle 75B configured in this way is attached to the bridge flow path member 13A in the same manner as the oblique nozzle 73 (see FIG. 5B) and the two-way nozzle 75A (see FIG. 5C). In the bridge flow path member 13A to which the three-way nozzle 75B is attached, the directivity increases from the half-split tube of the nozzle portion 75n when the temperature-controlled air A flowing out from the flow path 11f toward the recovery space RS flows out. The outflowing temperature-controlled air A and the temperature-controlled air A flowing out from the oblique pipe 75s overlap each other, and forced heat transfer can be increased while increasing the directivity, and the temperature-controlled air A to the floor panel 30 The amount of heat transferred to the air can be increased. The oblique nozzle 73, the two-way nozzle 75A, and the three-way nozzle 75B described above are typically made of a resin molded product or a metal pressed product.

Next, the floor panel 30A according to the first modification will be described with reference to FIG. 6 (A) is a front view of the floor panel 30A, FIG. 6 (A) is a side view of the floor panel 30A, and FIG. 6 (A) is a back view of the floor panel 30A. The floor panel 30A is typically installed in place of the floor panel 30 (see FIG. 1) in the heating and cooling system 100 (see FIG. 1). The floor panel 30A is configured by forming a plurality of elongated guide grooves 33 on the back surface (the surface facing the back side space S) of the floor panel 30 (see FIG. 1). In the present embodiment, the guide groove 33 extends from each side of the rectangular panel toward the opposite side to a position of about half of the distance to the opposite side, and the floor panel 30A is mounted on the support leg 15. When the opposite side is viewed from the side that is the starting point in the placed state, it is formed on the right side of the center of the side that is the starting point. Therefore, when the floor panel 30A is viewed from the side surface, the end surfaces of the plurality of guide grooves 33 appear on the right side of the center on the end surface of the side serving as the starting point (see FIG. 6B). ). With such a configuration, the guide groove 33 is formed so as to extend in a direction orthogonal to each of the rectangular floor panels 30A divided into four equal parts in a similar shape with respect to the adjacent portions. When the floor panel 30A configured in this way is incorporated into the heating / cooling system 100 instead of the floor panel 30, even if the air outlet 13f (see FIG. 4B) is not formed in the bridge flow path member 13. It may be (and the outlet 13f may be formed). Even when the air outlet 13f is not formed in the bridge flow path member 13, when the floor panel 30A is placed on the support leg 15, between the upper side of the side plate 13s of the bridge flow path member 13 and the floor panel 30A in contact with the upper side. A gap is formed in the portion of the guide groove 33. When the heating / cooling system 100 is activated, the temperature-controlled air A flowing through the flow path 11f flows out from the flow path 11f to the recovery space RS through the gap of the guide groove 33, and then guides extending toward the opposite sides. It follows the groove 33 and flows along the back surface of the floor panel 30A. As described above, when the floor panel 30A is adopted, the temperature-controlled air A flows along the guide groove 33, so that the temperature-controlled air A is suppressed from diffusing and a high flow velocity can be maintained. The heat transfer to the floor panel 30A can be increased.

7 (A) is a front view of the floor panel 30B according to the second modification, FIG. 7 (B) is a side view of the floor panel 30B, and FIG. 7 (C) is a back view of the floor panel 30B. The floor panel 30B is a member that serves as a base material when the panel to be the floor material is composed of the finishing material and the base material, and is a surface (in the recovery space RS) in contact with the finishing material 39 (see FIG. 7B). A group of guide grooves 33 similar to those formed on the floor panel 30A (see FIG. 6) is formed on the surface on the back side of the facing surface). Then, in the floor panel 30B, a through hole 33h penetrating the back surface is formed at the end of the guide groove 33 on the side opposite to the side that is the starting point of the guide groove 33. Further, in the present embodiment, the guide groove 33 extends so as to reach the back surface even at the end of the guide groove 33 on the side serving as the starting point. That is, in the present embodiment, when the floor panel 30B is viewed from the back side (the back side of the surface on which the guide groove 33 is formed), the guide groove 33 is located at a position corresponding to both ends of the guide groove 33 formed on the surface. The space (gap) leading to is appearing. When the floor panel 30B configured in this way is incorporated into the heating / cooling system 100 instead of the floor panel 30, it is preferable that the air outlet 13f (see FIG. 4B) is not formed in the bridge flow path member 13. .. If the air outlet 13f is not formed, the temperature-controlled air A in the flow path 11f flows out to the recovery space RS, so that the temperature-controlled air A passes through the guide groove 33 covered with the finishing material 39. The cold or hot heat possessed by the room R can be efficiently transferred to the panel serving as the floor material of the room R.

In the above description, it is assumed that the flow path member 11 is configured as an open culvert and forms the flow path 11f in cooperation with the floor panel 30, but the flow path member 11 is configured as an underdrain and is used alone. The flow path 11f may be formed (without the help of the floor panel 30). When the flow path member 11 is configured as an underdrain, the flow path member 11 is brought into contact with the floor panel 30 so that heat is transferred from the temperature-controlled air A flowing through the flow path 11f to the floor panel 30 via the flow path member 11. It is good to set it to. Further, the outlet 13f may penetrate the side plate 13s instead of the notch.

In the above description, in the flow path member system 10, one annular unit constituting the flow path member 11 is formed in a rectangular shape, and by connecting these in a grid pattern, the entire flow path member 11 can be formed. Although it was decided to construct it, one unit of ring may be formed as a hexagon to form a honeycomb as a whole, or one unit of ring may be formed as a rhombus or an appropriate polygon, and these may be formed on each side. It may be shared and linked. Further, in the above description, it is assumed that one unit of each ring has the same size, but the flow path 11f is relatively dense in the perimeter zone where the heating / cooling load is large and the region where the heat generating equipment is concentrated. It may be configured so that the flow path 11f is relatively sparse when the heating / cooling load is small. At this time, the cross flow path member 12 does not have to be provided on the support leg 15 in which the bridge flow path member 13 is not involved at all, and the bridge flow path member 13 is provided at two of the four ends of the cross flow path member 12, for example. If it is connected to, the remaining two ends may be closed.

In the above description, it is assumed that the supply space SS is formed in the outer peripheral portion of the entire flow path member 11 that spreads like a grid, and the recovery space RS is formed in the portion inside the supply space SS. However, the size and arrangement of the supply space SS and the recovery space RS can be appropriately changed depending on the situation.

In the above description, it is assumed that the inflow port 121 for entering the temperature-controlled air A from the supply space SS into the flow path 11f in the flow path member 11 is formed in the cross flow path member 12 arranged on the outermost side. However, the present invention is not limited to this, and may be formed on the side plate 13s of the bridge flow path member 13 at the portion located in the supply space SS, for example.

In the above description, the floor panel 30 is used as the partition member, but it may be used for a wall, a ceiling, or the like that partitions the room R other than the floor.
