Description

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

There is a steel floor in which a floor surface is formed by arranging multiple steel slats in parallel, arranging multiple steel joists on top of the steel slats so that they cross the steel slats, and laying flooring materials (corresponding to partition members that partition the rooms to be cooled and heated) on top of the steel joists. One method of using such a steel floor to heat and cool the space above the steel floor involves forming air flow paths inside the steel slats and steel joists, flowing temperature-conditioned air through these internal air paths, and transferring the cold or warmth of the temperature-conditioned air to the flooring, thereby cooling and heating using radiant heat from the flooring (see, for example, Patent Document 1).

JP 2010-112566 A

However, in the system described in Patent Document 1, due to its structure, the air that can transfer heat or cold to the flooring material is mainly the air that flows inside the joists and the air that flows out from the joists along the surface of the flooring material, and the heat or cold of the air that flows inside the joists is not easily transferred directly to the flooring material, which can lead to temperature unevenness in the flooring material as well as temperature unevenness inside the air-conditioned room.

In view of the above-mentioned problems, the present invention aims to provide a gas flow path forming system for heating and cooling, and a heating and cooling system that suppresses the occurrence of temperature unevenness in partition members whose temperatures are changed for heating and cooling.

To achieve the above object, the first aspect of the present invention provides a gas flow path forming system for cooling and heating, as shown in FIG. 1, for example. The gas flow path forming member 11 forms a gas flow path 11f through which temperature-adjusted gas A flows. The gas flow path forming member 11 is provided on the back side of a plate-shaped partition member 30 that partitions a room R to be cooled or heated, and extends linearly along the surface of the partition member 30 to form a ring shape, and forms the gas flow path 11f in cooperation with the partition member 30 or independently.

When configured in this manner, the gas flow path through which the temperature-adjusted gas flows is formed in a ring shape while extending linearly along the surface of the partition member, so by appropriately forming the size of the ring-shaped gas flow path, it is possible to prevent temperature unevenness from occurring in the partition member whose temperature has been changed.

In addition, as shown in FIG. 3, the gas flow path forming system for heating and cooling according to the second aspect of the present invention is the gas flow path forming system for heating and cooling according to the first aspect of the present invention 10, in which the gas flow path forming member 11 includes a cross flow path forming member 12 that forms an intersection of the gas flow paths 11f and a bridge flow path forming member 13 that connects between the two cross flow path forming members 12; and further includes a support member 15 that supports the partition member 30 (see FIG. 1, for example) and also supports the cross flow path forming member 12.

In this configuration, a gas flow path can be formed by combining common parts, and the number of parts can be reduced and the system simplified by sharing the same parts for supporting the flow path forming member and the partition member.

In addition, as shown in FIG. 2, the third aspect of the present invention is a gas flow path forming system for heating and cooling, which is the gas flow path forming system 10 for heating and cooling according to the first or second aspect of the present invention, and the gas flow path forming member 11 is configured to have a plurality of annular gas flow paths 11f formed therein, and to have adjacent ones of the plurality of annular gas flow paths 11f share a portion of the gas flow paths 11f, thereby allowing the plurality of annular gas flow paths 11f to communicate with each other.

This configuration allows the annular gas flow path to be expanded, expanding the range over which the temperature of the partition member can be changed.

The cooling and heating system according to the fourth aspect of the present invention, as shown in FIG. 1, includes a gas flow path forming system 10 for cooling and heating according to any one of the first to third aspects of the present invention; a partition member 30 that partitions the room R to be cooled and heated; a partition member 20 that partitions the space S behind the partition member 30 and outside the gas flow path into a supply space SS to which temperature-adjusted gas A is supplied and a recovery space RS into which the temperature-adjusted gas A supplied to the supply space SS flows after approaching the temperature inside the room R to be cooled and heated; and a temperature adjustment device 61 that supplies the temperature-adjusted gas A toward the supply space SS. The gas flow path forming member 11 is configured such that an inlet 121 is formed in a portion located in the supply space SS, through which the temperature-adjusted gas A supplied to the supply space SS flows into the gas flow path.

When configured in this way, the temperature-adjusted gas supplied to the supply space can be made to flow into the recovery space via the gas flow path, changing the temperature of the partition member and cooling or heating the cooling room.

In addition, as shown in Figures 1, 3 and 4(B), the heating and cooling system according to the fifth aspect of the present invention is the heating and cooling system 100 according to the fourth aspect of the present invention, in which the gas flow path forming member 11 is formed in a portion located in the recovery space RS with a discharge port 13f (see Figures 3 and 4(B)) that discharges the temperature-adjusted gas A that has flowed into the gas flow path 11f along the surface of the partition member 30.

This configuration allows the temperature-adjusted gas to come into contact with a wide area of the partition member's surface, allowing the temperature of the partition member to be changed efficiently.

In addition, as shown in Figures 6 and 7, the heating and cooling system according to the sixth aspect of the present invention is the heating and cooling system according to the fourth or fifth aspect of the present invention, and the partition members 30A and 30B are configured such that a guide groove 33 leading from the inside to the outside of the gas flow path is formed in the portion located in the recovery space RS (see Figure 1, for example).

When configured in this manner, the temperature-adjusted gas flowing through the gas flow path reaches the recovery space via the guide groove, and the temperature of the partition member can be efficiently changed by the temperature-adjusted gas flowing along the guide groove.

According to the present invention, the gas flow path through which the temperature-adjusted gas flows is formed in a ring shape while extending linearly along the surface of the partition member, so that by appropriately forming the size of the ring-shaped gas flow path, it is possible to suppress the occurrence of temperature unevenness in the partition member whose temperature has been changed.

Below, an embodiment of the present invention will be described with reference to the drawings. Note that in each drawing, identical or similar reference numerals are used for the same or corresponding components, and duplicate explanations will be omitted.

First, referring to FIG. 1, a cooling and heating system 100 according to an embodiment of the present invention will be described. FIG. 1 is a perspective view showing a schematic configuration of the cooling and heating system 100. The cooling and heating system 100 is a system for mainly cooling or heating (hereinafter referred to as "cooling and heating") a room R as a room to be cooled and heated. The cooling and heating system 100 includes a flow path member system 10 according to an embodiment of the present invention that forms a flow path for air (corresponding to temperature-adjusted gas, hereinafter referred to as "temperature-adjusted air A") adjusted to a temperature suitable for radiant heating and cooling of the room R in the space S behind the room R, a partition member 20 that divides the back space S, a floor panel 30 that divides the room R from the back space S, a temperature adjustment device 61 that generates the temperature-adjusted air A, and a duct 63 that guides the temperature-adjusted air A from the temperature adjustment device 61 to the back space S. The temperature-adjusted air A is typically cooled air when the room R is cooled, and heated air when the room R is heated. The heating and cooling system 100 shown in FIG. 1 is shown with a portion of the floor panel 30 removed to show the configuration of the back space S, but when the room R is used (when the heating and cooling system 100 is completed), the floor panel 30 will be laid out. Each element that makes up the heating and cooling system 100 will be explained below.

2 shows a schematic configuration of the flow path member system 10. FIG. 3 shows a part (one section) of the flow path member system 10 shown in FIG. 2. The flow path member system 10 is a system that forms a flow path for temperature-controlled air A in the back 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 a support leg 15. The flow path member 11 is a member for forming a flow path 11f (corresponding to a gas flow path) of the temperature-controlled air A so as to extend linearly along the back surface of the floor panel 30, and corresponds to a gas flow path forming member. In this embodiment, the flow path 11f is formed so that a basic unit is formed in a ring shape that follows the outer periphery of a square, and multiple flow paths 11f are arranged adjacent to the periphery like a checkerboard, while sharing the sides of adjacent squares. Here, "annular" means that the start point and end point of the line are connected and continuous, and the outer shape can be a square as in this embodiment, or a rectangular shape such as a rectangle, a quadrilateral such as a rhombus, a pentagon, or a polygon such as a hexagon, or a circle or ellipse, and typically the shape should match the contour of the floor panel 30.

In this embodiment, the flow path 11f is formed exclusively on the same imaginary plane, which is different from the conventional case where the intersecting sides are staggered when tensile steel beams and joist steel beams are used. In addition, in this embodiment, the cross section of the flow path 11f perpendicular to the flow direction of the temperature-controlled air A inside is rectangular. In this embodiment, the flow path member 11 is configured as an open channel, and the flow path 11f is formed by blocking the open part with the floor panel 30, in other words, the flow path 11f is formed in cooperation with the floor panel 30. In this embodiment, the flow path member 11 has a cross flow path member 12 that forms a corner part of the square of the basic unit, and a bridge flow path member 13 that forms one side of the square.

4A is a perspective view of the cross flow path member 12. The cross flow path member 12 is a member that forms the 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 formed of steel plates, but may be formed of resin plates or the like. The bottom plate 12t has a cross shape that is formed by cutting out the four corners of a 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 perpendicularly to the bottom plate 12t from a portion corresponding to the side of the 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 relative to the bottom plate 12t. The cross flow path member 12 has a cross flow path height 12h, which is the height of the side plates 12s (the length in the direction perpendicular to the surface of the bottom plate 12t), which corresponds to the height of the flow path 11f, and a cross flow path width 12w, which is the width of the bottom plate 12t between the opposing side plates 12s, which corresponds to the width of the flow path 11f.

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 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 formed of the same material as the cross flow path member 12, but may be formed of a material different from the cross flow path member 12. The bottom plate 13t is formed in an elongated rectangle. The side plate 13s is formed in an elongated rectangle, and is provided so as to extend perpendicularly to the bottom plate 13t from each of a pair of long sides of the rectangle of the bottom plate 13. A total of two side plates 13s extend in the same direction relative to the bottom plate 13t. Each side plate 13s has a locking piece 13k at one end in the longitudinal direction. The locking piece 13k extends perpendicularly to the side plate 13s and outward (opposite the flow path 11f). The locking piece 13k is formed to be roughly the same size (the same size or slightly smaller) as one of the side edges 12s (see FIG. 4A) of the cross flow path member 12. The locking pieces 13k, one on each of the pair of side plates 13s, are located at diagonal corners of 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 perpendicular to the surface of the bottom plate 13t), corresponds to the height of the flow path 11f, and the bridge flow path width 13w, which is the width of the bottom plate 13t between the opposing side plates 13s, corresponds to the width of the flow path 11f.

Some bridge flow path members 13 have an air outlet 13f formed in the side plate 13s. The air outlet 13f is an opening formed to discharge the temperature-controlled air A inside the flow path 11f to the outside of the flow path 11f along the back surface of the floor panel 30 when the open upper portion of the bridge flow path member 13 is blocked by the floor panel 30 (see FIG. 1), and corresponds to a discharge port. In this embodiment, the air outlet 13f is formed by cutting out a semicircular shape in the upper edge of the side plate 13s (the long side of the side plate 13s opposite to the long side that contacts the bottom plate 13t). The air outlets 13f are spaced apart in the longitudinal direction such that there is some overlap between the temperature-controlled air A discharged from adjacent air outlets 13f, forming a set of multiple outlets (typically two, but may be three or more), and are spaced apart in the longitudinal direction such that the temperature-controlled air A discharged from each outlet 13f in a set does not interfere with the temperature-controlled air A discharged from each outlet 13f in an adjacent set. The positions at which the air outlets 13f are formed relative to the entire longitudinal direction of the bridge flow path member 13 will be described later.

Figure 4 (C) is an exploded perspective view of the support leg 15. In addition, in Figure 4 (C), the cross flow path member 12 is shown in addition to the components 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 that can support the cross flow path member 12 and the floor panel 30, and corresponds to a support member. The support leg 15 is typically used by being placed on the 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 screw 16 has a length from the floor slab to the height at which the floor panel 30 is installed, and is 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 in this embodiment, it is formed in a rectangular plate shape. The receiving plate 18 has a hole 18p formed in the approximate center through which the full screw 16 can pass, and is supported by a receiving plate nut 185. The receiving plate nut 185 is screwed onto the full screw 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 relative to the full screw 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 the full screw 16 into an insertion hole (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 has a hole 19p formed in the approximate center through which the full screw 16 can pass. The support plate 19 is supported by a support plate nut (not shown) screwed onto the full screw 16 and 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 relative to the full screw 16. The support leg 15 uses a full thread 16, so that 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 thread 16.

3, the bridge flow path member 13 is assembled to the cross flow path member 12 so that the bottom plate 13t of one end of the bridge flow path member 13 is placed on the bottom plate 12t of the cross flow path member 12. In detail, the locking piece 13k of one end of the bridge flow path member 13 is placed on the bottom plate 12t of the cross flow path member 12 and contacts the side plate 12s connected to the side plate 12s of the cross flow path member 12 that sandwiches the bridge flow path member 13 from the flow path 11f side. By performing this for necessary parts of the four openings of the cross flow path member 12, a ring-shaped flow path 11f can be formed along the outer edge of a square as shown in FIG. 3, and by further expanding this, a network of flow paths 11f that spreads out like a checkerboard as shown in FIG. 2 can be formed. At this time, the interval between the cross flow path members 12, i.e., the interval between the support legs 15, is preferably set to an interval that can stably support the floor panel 30, and the length of the bridge flow path member 13 may be determined according to this interval. 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 may be omitted from the support leg 15, and the cross flow path member 12 may not be incorporated in the support leg 15. In the flow path member system 10, a network of flow paths 11f of any 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 construction can be simplified while the production cost can be reduced. In addition, since the basic structure of the bridge flow path member 13 installed between each cross flow path member 12 is common, the width of the flow path 11f becomes uniform at each location, and the occurrence of a difference in pressure loss at each location can be suppressed. In addition, the bridge flow path members 13 at each location are incorporated into four openings at the same height of the cross flow path member 12, so that the flow path members 11 extend on the same imaginary plane, and this configuration also contributes to suppressing differences in pressure loss at each location.

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 above the floor slab, so the entire flow path member 11 is floating above 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 on the flow path member system 10 having the flow path members 11 that spread out like a checkerboard as shown in Figure 2, a back space S is formed between the floor panel 30 and the floor slab, through which fluids such as air can flow and which functions as an underfloor chamber.

The configuration of the air conditioning system 100 other than the flow path member system 10 will be described below with reference mainly to FIG. 1 and, as appropriate, to FIGS. 2 to 4. The partition member 20 is a member for dividing the back space S into a supply space SS and a recovery space RS. The supply space SS is a space into which the temperature-controlled 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 into which the temperature-controlled air A discharged from the flow path 11f through the air outlet 13f (see FIG. 4B) in this embodiment is received. In this embodiment, the supply space SS is formed on the outer periphery of the entire flow path member 11, which spreads out like a checkerboard, and the recovery space RS is formed in the part inside the supply space SS. The partition member 20 is formed of a plate-shaped member, and is configured so that its 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 leg 15. The partition member 20 is typically constructed by connecting pieces of appropriate size in the direction in which the surface of the floor slab extends. The partition member 20 does not extend inside the flow path 11f, and the part that interferes with the flow path member 11 is cut out to avoid the flow path member 11.

The outermost one of the cross flow path members 12 arranged in the supply space SS has an opening portion without the bridge flow path member 13 being incorporated among the four flow paths 11f formed by being sandwiched between the opposing side plates 12s, and this opening portion serves as an inlet 121 through which the temperature-controlled air A flows from the supply space SS into the flow path member 11. The inlet 121 is typically formed in all of the cross flow path members 12 arranged at the outermost side, but the number of inlets 121 may be limited by blocking any opening. With respect to the bridge flow path member 13, the aforementioned blowing port 13f is formed in the side plate 13s facing the recovery space RS. The blowing port 13f is formed on one side of the center when viewed in the longitudinal direction for each bridge flow path member 13, and in this embodiment, it is formed on the right side of the center when viewed from the flow path 11f through the side plate 13s toward the recovery space RS. With this configuration, the temperature-controlled air A discharged from within the flow path 11f into the recovery space RS through the outlet 13f of one bridge flow path member 13 is mainly supplied to a portion of 1/4 of the area of the square recovery space RS surrounded by the four bridge flow path members 13 in a plan view, and the temperature-controlled air A discharged from the outlets 13f of the four bridge flow path members 13 that make up the outer edge of the recovery space RS works together to supply the temperature-controlled air A to the entire square recovery space RS.

As described above, the floor panel 30 is a partition member that partitions the room R and the back space S. The floor panel 30 is typically formed in a rectangular plate shape with the length of one side being the length between the adjacent cross flow path members 12 of the flow path member 11 installed on the floor slab. The floor panel 30 is typically a panel for flooring or a free access floor, and may be configured to be divisible into a finishing material and a base material. In this embodiment, the floor panel 30 is formed to be generally flat on both the front and back sides. The flatness referred to here is sufficient if it is within a range that is generally recognized as flat as a floor material, and for example, even if there is a slight gap that appears at the connection part of multiple boards in flooring, it is included in the range of flatness. Most of the floor panels 30 that constitute the floor surface of the room R are configured to cover the entire surface without openings, etc., but some are replaced with supply panels 30p and recovery panels 30q. The supply panel 30p has an opening to which the duct 63 is connected, and is located at a position where the opening communicates with the supply space SS. The collection panel 30q has a return port 30qh, which is an opening that can guide the air in the collection space RS to the room R, and the return port 30qh is disposed at a position that communicates with the collection space RS. A grill (grating) is installed in the return port 30qh of the collection panel 30q.

The temperature control device 61 is a device that generates temperature-controlled air A adjusted to a temperature that can perform radiant heating and cooling of the room R, and corresponds to a temperature control device. The temperature control device 61 is typically a packaged air conditioner, but an air handling unit or a room air conditioner may also be used. In this embodiment, the temperature control device 61 is placed outside the room R, and is configured so that the temperature-controlled 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. The temperature control device 61 may also be installed near the supply panel 30p in the room R, and in this case, if the temperature-controlled air A flowing out from the temperature control device 61 can be directly supplied to the supply space SS, the duct 63 does not need to be provided.

The operation of the flow path member system 10 and the air conditioning system 100 will be described below with reference to Figures 1 to 4. The operation of the flow path member system 10 will be described below as part of the operation of the air conditioning system 100. The temperature control device 61 generates temperature-controlled air A adjusted to a temperature suitable for radiant cooling and heating of the room R (depending on the set temperature, for example, 18 to 23°C for cooling and 30 to 35°C for heating). Radiant cooling and heating is generally designed to reduce the difference between the temperature of the temperature-controlled air and the outside air temperature compared to cooling and heating by convection alone (cooling and heating performed by supplying temperature-controlled air into a cooling and heating room), so less energy is required to generate the temperature-controlled air A. The temperature-controlled air A generated by the temperature control device 61 flows into the supply space SS through the duct 63 and the opening of the supply panel 30p. The temperature-controlled air A that flows into the supply space SS from the opening of the supply panel 30p diffuses throughout the supply space SS and flows from the inlet 121 into the flow paths 11f formed inside the flow path member 11. The temperature-controlled air A that flows into the flow paths 11f from the inlet 121 diffuses approximately uniformly throughout the flow paths 11f of the flow path member 11 that spreads out like a checkerboard, because the width of each flow path 11f that constitutes the flow path member 11 that spreads out like a checkerboard is uniform and at the same height in each location, thereby suppressing the occurrence of differences in pressure loss.

The temperature-controlled air A that has spread throughout the entire flow path 11f flows out from the air outlet 13f and is released into the recovery space RS. At this time, the air outlet 13f is formed on the upper edge of the side plate 13s that contacts the floor panel 30, so 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 transfers cold heat (when cooling) or warm heat (when heating) to the floor panel 30. As a result, the floor panel 30 is cooled or heated. Here, it is preferable that the size of the cutout that forms the air outlet 13f is formed to an opening area at which the flowing out temperature-controlled air A flows at a wind speed that destroys the boundary film (a very thin region that exists at the phase boundary when the fluid is in relative motion and maintains a laminar flow state) formed between the floor panel 30 and the air outlet 13f. Generally, if there is a boundary film where air stagnates between the floor panel 30 and the flow of the temperature-controlled air A, the surface heat transfer resistance increases, and the cold or warmth contained in the temperature-controlled air A is not efficiently transferred to the floor panel 30, but the heat transfer rate can be improved by breaking the boundary film. In addition, the air outlet 13f is formed so that the temperature-controlled air A discharged from adjacent ones constituting one set overlaps with each other, so the air flow speed in the overlapping part increases, the reach is extended, and the forced heat transfer increases, so that 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 heated by the temperature-controlled air A, the cold or warmth is radiated from the cooled or heated floor panel 30 to the room R, and the room R is cooled or heated.

The temperature-controlled air A that has transferred cold or hot heat to the floor panel 30 rises in temperature during cooling and falls in temperature during heating. The temperature-controlled air A that has exchanged 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 circulates within the room R. The temperature-controlled air A that flows 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, so it contributes to the heating and cooling of the room R. The temperature-controlled air A that flows into the room R through the return port 30qh then flows out to the outside through a door louver (not shown) or the like. The temperature-controlled air A that flows out to the outside flows into the supply space SS from the temperature control device 61 through the duct 63 and the opening of the supply panel 30p, and the above-mentioned action is repeated thereafter.

As described above, according to the air conditioning system of this embodiment, the flow path 11f of the flow path member system 10 of this embodiment, which is one of the elements constituting this air conditioning system, is formed in a series of square rings that spread out like a checkerboard and have a uniform width and height in each place, so that it is possible to suppress temperature unevenness in the floor panel 30, whose temperature changes due to heat transfer from the temperature-controlled air A discharged from the air outlet 13f, and it is possible to perform roughly uniform air conditioning and heating in the room R. In addition, the cross flow path member 12 and bridge flow path member 13, which are the constituent members of the flow path member 11, are basically formed of the same materials and are constructed by combining these, so that the construction can be simplified while production costs can be suppressed.

Next, referring to FIG. 5, a bridge flow path member 13A according to a modified example will be described. FIG. 5(A) 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, a connecting portion 70 is provided instead of the air outlet 13f (see FIG. 4(B)) formed in a semicircular shape on the side plate 13s in the above-mentioned bridge flow path member 13 (see FIG. 4(B)). The connecting portion 70 includes a connecting hole 71 formed by cutting out a rectangle from the upper side of the side plate 13s toward the bottom plate 13t. In this 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 guides 72 are slits (elongated cuts) for attaching parts to be described later to the connecting portion 70. The connection guide 72 is formed at the same depth as the connection hole 71. Since one set of the air outlets 13f formed in the bridge flow path member 13 (see FIG. 4B) corresponds to one of the connection parts 70, only one connection part 70 is shown in FIG. 5A, but typically the same number of connection parts 70 as the number of sets of the air outlets 13f formed in the bridge flow path member 13 (see FIG. 4B) are formed in the bridge flow path member 13A.

Figure 5 (B) is a perspective view of the oblique nozzle 73, which is an example of a part attached to the connecting part 70. The oblique nozzle 73 has a blocking plate 73c including a nozzle portion 73n and a rail 73r. The blocking plate 73c is formed to be approximately the same size as the connecting hole 71 so that the connecting hole 71 is blocked when the oblique nozzle 73 is attached to the connecting part 70. The nozzle portion 73n provided on the blocking plate 73c is composed of a pair of side plates 73e and one slanted plate 73s that surround a rectangular opening formed by cutting the blocking plate 73c. The pair of side plates 73e are parallel to the left and right sides of the blocking plate 73c and extend perpendicular to the surface of the blocking plate 73c. The slanted plate 73s is provided below the space between the pair of side plates 73e. The nozzle portion 73n is typically configured in such a manner that a pair of notches extending vertically downward from the upper side of a rectangular thin plate are formed at a horizontal interval, and the portion sandwiched between the notches is bent outward (for example, at 30° or 45°) by a virtual straight line connecting the lower ends of the pair of notches, and the bent portion is made into a swash plate 73s, and a pair of side plates 73e are attached to close the gap between the blocking plate 73c and the swash plate 73c created by bending the swash plate 73s. The nozzle portion 73n configured in this manner is formed so that the opening area of the cross section becomes smaller as it moves from the blocking plate 73c side to the tip side, and an outlet port 73p is formed at the farthest portion from the blocking plate 73c. The outlet port 73p corresponds to a discharge port. With this configuration, the gas discharged from the outlet port 73p of the nozzle portion 73n is configured to be a jet. The rails 73r are elongated members with an L-shaped cross section, and are provided on both the left and right sides of the blocking plate 73c. The distance between the pair of rails 73r provided on both the left and right sides of the blocking plate 73c is equal to the distance between the pair of connecting guides 72 provided on the connecting portion 70. In the explanation of the oblique nozzle 73 here, for convenience, the blocking plate 73c and the rails 73r are described separately, but typically, one thin plate is folded and formed as one piece. The gap formed between the rails 73r and the blocking plate 73c is approximately the same as the thickness of the side plate 13s of the bridge flow path member 13A. To attach the oblique nozzle 73 to the connecting portion 70, the side of the blocking plate 73c opposite to the side where 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 are fitted into the pair of slits of the connecting guide 72, and the oblique nozzle 73 is brought close to the bottom plate 13t.

Figure 5 (C) is a perspective view of a two-way nozzle 75A, which is another example of a part attached to the connecting portion 70. The two-way nozzle 75A has a blocking plate 75c including a nozzle portion 75n, and a rail 75r. Compared to the oblique nozzle 73 (see Figure 5 (B)), the two-way nozzle 75A differs in that instead of the nozzle portion 73n (see Figure 5 (B)) provided in the oblique nozzle 73, a nozzle portion 75n having a plurality of short half-split tubes is provided. Therefore, the blocking plate 75c of the two-way nozzle 75A corresponds to the blocking 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 blocking plate 75c of the two-way nozzle 75A has a semicircular notch on the upper side similar to the air outlet 13f (see FIG. 4B), and a half-split short tube is attached so as to extend perpendicularly from the notch to the surface of the blocking plate 75c. The tip of this half-split short tube corresponds to the discharge port. The two-way nozzle 75A configured in this manner 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 from the flow path 11f toward the recovery space RS flows into the recovery space RS after the flow path is restricted by the half-split tube of the nozzle part 75n, so that the directionality is increased and the reach is longer than that of the temperature-controlled air A discharged from the air outlet 13f, allowing for efficient heating and cooling.

Figure 5 (D) is a perspective view of a three-way nozzle 75B, which is yet another example of a part attached to the connecting portion 70. The three-way nozzle 75B differs from the two-way nozzle 75A (see Figure 5 (C)) in that, in addition to the configuration of the two-way nozzle 75A, a diagonal tube 75s is added below the nozzle portion 75n. The diagonal tube 75s is composed of a short tube having a diameter similar to that of the half-split tube that constitutes the nozzle portion 75n, and is attached at an angle to the surface of the blocking plate 75c so that it approaches the half-split tube of the nozzle portion 75n as it moves away from the blocking plate 75c. The diagonal tube 75s is inclined at an angle of about 30° to 45° to the blocking plate 75c. In the three-way nozzle 75B, in addition to the tip of the half-split short tube, the tip of the diagonal tube 75s also corresponds to the discharge port. The three-way nozzle 75B configured in this manner 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, when the temperature-controlled air A flows out from the flow path 11f toward the recovery space RS, the temperature-controlled air A that flows out from the half-split tube of the nozzle portion 75n with increased directivity overlaps with the temperature-controlled air A that flows out from the oblique tube 75s, increasing the directivity and increasing the forced heat transfer, thereby increasing the amount of heat transferred from the temperature-controlled air A to the floor panel 30. The oblique nozzle 73, two-way nozzle 75A, and three-way nozzle 75B described above are typically made of resin molded products or metal pressed products.

Next, the floor panel 30A according to the first modified example will be described with reference to FIG. 6. 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 air-conditioning system 100 (see FIG. 1). The floor panel 30A is configured by forming a plurality of elongated guide grooves 33 on the back surface (surface facing the back space S) of the floor panel 30 (see FIG. 1). In this embodiment, the guide grooves 33 extend from each side of the rectangular panel toward the opposing side to a position that is approximately half the distance to the opposing side, and are formed to the right of the center of the side that is the starting point when the opposing side is viewed from the side that is the starting point with the floor panel 30A placed on the support leg 15. Therefore, when the floor panel 30A is viewed from the side, the ends of the guide grooves 33 are shown on the end face of the side that is the starting point, to the right of the center (see FIG. 6B). With this configuration, the guide grooves 33 are formed in each of the four equal parts of the rectangular floor panel 30A that are similar to each other, so as to extend in a direction perpendicular to the adjacent parts. When the floor panel 30A configured in this way is incorporated into the heating and cooling system 100 in place of the floor panel 30, the bridge flow path member 13 does not need to have an air outlet 13f (see FIG. 4B) (or the air outlet 13f may be formed). Even if the bridge flow path member 13 does not have an air outlet 13f, when the floor panel 30A is placed on the support leg 15, a gap is formed in the guide groove 33 between the upper side of the side plate 13s of the bridge flow path member 13 and the floor panel 30A in contact therewith. When the air conditioning system 100 is operating, the temperature-controlled air A flowing through the flow path 11f flows out of the flow path 11f into the recovery space RS through the gap in the guide groove 33, and then follows the guide groove 33 that extends toward the opposing side and flows along the back surface of the floor panel 30A. In this way, when the floor panel 30A is used, the temperature-controlled air A flows along the guide groove 33, so that the diffusion of the temperature-controlled air A is suppressed, a high flow rate can be maintained, and heat transfer to the floor panel 30A can be increased.

Figure 7 (A) is a surface view of a floor panel 30B according to a second modified example, Figure 7 (B) is a side view of the floor panel 30B, and Figure 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 that serves as a floor material is composed of a finishing material and a base material, and a group of guide grooves 33 similar to those formed in the floor panel 30A (see Figure 6) is formed on the surface that contacts the finishing material 39 (see Figure 7 (B)) (the surface behind the surface facing the recovery space RS). In the floor panel 30B, a through hole 33h that penetrates the back surface is formed at the end of the guide groove 33 on the opposite side to the side that is the starting point of the guide groove 33. In this 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 that is the starting point. That is, in this 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), a space (gap) leading to the guide groove 33 is visible at positions corresponding to both ends of the guide groove 33 formed on the surface. When the floor panel 30B configured in this way is incorporated into the heating and cooling system 100 in place of the floor panel 30, it is preferable that the outlet 13f (see FIG. 4B) is not formed in the bridge flow path member 13. If the outlet 13f is not formed, the temperature-controlled air A in the flow path 11f passes through the guide groove 33 covered by the finishing material 39 to flow out to the recovery space RS, and the cold or hot heat held by the temperature-controlled air A can be efficiently transferred to the panel that serves as the floor material of the room R.

In the above explanation, the flow path member 11 is configured as an open conduit and cooperates with the floor panel 30 to form the flow path 11f, but the flow path member 11 may be configured as a culvert and form the flow path 11f by itself (without the aid of the floor panel 30). When the flow path member 11 is configured as a culvert, it is preferable to bring the flow path member 11 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. Also, the air outlet 13f may be formed by penetrating the side panel 13s rather than by a notch.

In the above description, in the flow path member system 10, each annular unit constituting the flow path member 11 is formed in a rectangular shape, and the flow path member 11 is formed as a whole by connecting these units in a checkerboard pattern. However, each annular unit may be formed in a hexagonal shape to form a honeycomb shape as a whole, or each annular unit may be formed in a rhombus or other suitable polygonal shape to connect these units by sharing each side. In addition, in the above description, each annular unit is assumed to be the same size, but the flow paths 11f may be configured to be relatively dense in the perimeter zone where the cooling and heating load is large and in the area where heat-generating devices are concentrated, and may be configured to be relatively sparse when the cooling and heating load is small. In this case, the cross flow path member 12 may not be provided on the support leg 15 where the bridge flow path member 13 is not involved at all, and when the bridge flow path member 13 is connected to, for example, two of the four ends of the cross flow path member 12, the remaining two ends may be blocked.

In the above explanation, the supply space SS is formed on the outer periphery of the entire flow path member 11, which spreads out like a checkerboard, and the recovery space RS is formed on the inner side of the supply space SS, but the size and arrangement of the supply space SS and the recovery space RS can be changed as appropriate depending on the situation.

In the above explanation, the inlet 121 for allowing the temperature-controlled air A to enter the flow path 11f in the flow path member 11 from the supply space SS is formed in the cross flow path member 12 located at the outermost position, but this is not limited thereto, and it may be formed, for example, in the side plate 13s of the bridge flow path member 13 in the portion located in the supply space SS.

In the above explanation, the partition member is the floor panel 30, but it may also be used for walls, ceilings, etc. that partition the room R other than the floor.
