Description

  The present invention relates to an air conditioning system, and more particularly to an air conditioning system that performs air conditioning with radiant heat.

  In recent years, a radiant cooling and heating system that performs cooling and heating with radiant heat has attracted attention as a cooling and heating method that achieves both energy saving and comfort. A radiant cooling / heating system is a system that adjusts the temperature of a cooling / heating room by radiant heat from a ceiling surface, a floor surface, or the like that is cooled or heated by cooling a ceiling surface or a floor surface during cooling and heating it during heating. Heating and cooling by radiant heat is comfortable because extreme temperature unevenness does not occur in the room, and the amount of heat required for cooling or heating the ceiling surface, floor surface, etc. is less than that of a so-called convection type air conditioning system. For this reason, the radiation cooling and heating system can be said to be a more energy-saving system.

  As an example of a radiant cooling and heating system, a plurality of heat medium diffusion members are installed through ducts at appropriate positions on the back side of a section screen that forms a target room in which air conditioning is performed, and the air flow direction conversion that the heat medium diffusion member has By converting the gas heat medium that has flowed substantially perpendicular to the back of the section screen into a flow along the section screen by the action of the vessel, the heat medium can be diffused widely along the section screen and efficiently There is one in which heat is transmitted to a section screen of a room to be air-conditioned, and the room to be air-conditioned is cooled or heated by radiant heat from the section screen to which the heat has been transmitted (for example, see Patent Document 1).

  However, according to the above-described radiation cooling / heating system, a good radiation effect can be obtained. However, in order to uniformly cool or heat the entire surface of the flooring material, a large number of airflow direction changers are required, and the effort and cost of system construction are reduced. It had increased.

  In view of the above-described problems, an object of the present invention is to provide an air conditioning system that can cool or heat the entire partition material evenly while suppressing an increase in construction effort and cost.

  In order to achieve the above object, an air conditioning system according to a first aspect of the present invention includes a lip channel steel 11 having a predetermined length, for example, as shown in FIG.

  If comprised in this way, since the gas derived | led-out from the outlet port contacts the back surface of a division material at a predetermined angle, gas is diffused along the back surface of a division material rather than contacting the back surface of a division material perpendicularly. Can do.

  Moreover, the air conditioning system which concerns on the 3rd aspect of this invention is a lip | rip from the outlet 12h in the air conditioning system which concerns on the said 1st aspect or 2nd aspect of this invention, for example, as shown in FIG.1 and FIG.3. A cylindrical dynamic pressure extraction member 30 that is inserted into the channel steel 11 and has an introduction opening surface 31f that introduces an internal gas flow (flow of gas SA) that flows through the inside of the lip channel steel 11. In addition, a dynamic pressure extraction member 30 is provided in which an introduction opening surface 31f is disposed to face the internal gas flow at a second predetermined angle D.

  If comprised in this way, the flow volume of the gas derived | led-out from an outlet can be increased compared with the case where a dynamic-pressure extraction member is not provided.

  Moreover, the air conditioning system which concerns on the 4th aspect of this invention is a lip | rip from the outlet 12h in the air conditioning system which concerns on the said 1st aspect or this 2nd aspect of this invention, for example, as shown in FIG.1 and FIG.4.

  Embodiments of the present invention will be described below with reference to the drawings. In the drawings, the same or similar members are denoted by the same or similar reference numerals, and redundant description is omitted.

  With reference to FIG.1 and FIG.2, the air conditioning system 1 which concerns on embodiment of this invention is demonstrated. FIG. 1 is a diagram for explaining a part of the configuration of an air conditioning system 1, (a) is a sectional view, and (b) is a partial perspective view of a stud duct 10 that constitutes the air conditioning system 1. FIG. 2 is a perspective view showing a schematic configuration of the air conditioning system 1 and shows a state in which the floor material 15 as the partition material shown in FIG. 1 is removed. The air conditioning system 1 includes a lip groove steel (a so-called C-shaped steel, hereinafter referred to as “C-chan”) 11 and a flat plate 12 constituting a stud duct 10, and a temperature control that is a gas whose temperature is adjusted in the stud duct 10. A forward flow chamber 25A as a first chamber for supplying air SA and a reverse flow chamber 25B as a second chamber are provided, and a temperature adjustment device 21 as a temperature adjustment device for generating the temperature adjustment air SA is provided.

  The C-chan 11 is formed in a C-shape in which a longitudinal opening 11h which is a strip-shaped opening is formed along the longitudinal direction on one side surface of a hollow cylinder having a rectangular cross section (rectangle or square) as a basic shape, and the cross section perpendicular to the axis is square. Long member. Typically, the C-chang 11 is mass-produced by bending a long and narrow steel plate (for example, a hot-dip galvanized steel plate) along the longitudinal direction in a factory. In the present embodiment, the C-chan 11 is a steel plate having a thickness of 1.6 mm, in which a long side 11 a facing the long opening 11 h has a length of 100 mm and extends short from both ends of the long side 11 a in a cross section perpendicular to the axis. The length of the side 11b is 50 mm, the length of the side 11c that is located on both sides of the long opening 11h and continues to the short side 11b is 20 mm (thus the width of the long opening 11h is 60 mm), and the length is 4 m. What is produced in a factory in a state is appropriately cut and used (to a predetermined length) so as to be compatible with the air conditioning system 1 to be constructed. In addition, the characteristics such as the size and material of the C-chang 11 are not limited thereto, and may be appropriately selected according to the cooling / heating system 1 to be constructed.

  The flat plate 12 is a member for constituting the stud duct 10 that blocks the entire longitudinal opening 11h of the C-chan 11 and functions as a wind guide. The flat plate 12 typically has the same width as the long side 11 a of the C-chan 11 and a steel plate having the same length as the C-chan 11 is used. However, the width of the flat plate 12 may be shorter than the long side 11a as long as the long opening 11h can be closed. The flat plate 12 is formed with a plurality of outlets 12h through which the temperature-controlled air SA flowing inside when the stud duct 10 is configured is led out of the stud duct 10. A large number of outlets 12h are formed at intervals in the longitudinal direction. Furthermore, two rows of the outlets 12h formed along the longitudinal direction are formed in two rows at intervals in the width direction. Each outlet 12h has a rectangular outline 12r having a side parallel to the longitudinal side of the flat plate 12, and one side inside the outline 12r marked before cutting (in the width direction of the flat plate 12). 3 sides are cut (notched), leaving the side closest to the adjacent row as a connecting side 12s as a connecting portion, and the folded piece 12p formed inside the cut three sides, It is formed by bending the connecting side 12s to the outside of the C-chan 11. The distance between the outer side of one outlet 12h (side facing the connecting side 12s) and the outer side of the other outlet 12h in the width direction of the flat plate 12 of the outlets 12h formed in two rows is The width of the longitudinal opening 11h of the C-chan 11 is equal to or smaller than the width.

  The above-described C-chan 11 and the flat plate 12 are placed on both sides 11c so that both edges extending in the longitudinal direction of the flat plate 12 are placed so that each outlet 12h is located on the long-side opening 11h. The stud duct 10 is configured by appropriately fastening a portion where the flat plate 12 and the flat plate 12 overlap with a tapping screw or the like. In this way, the stud duct 10 cuts the ready-made C-chan 11 to a predetermined length at the factory or the site (the place where the air-conditioning system 1 is constructed), and the contour 12r on three sides other than the connecting side 12s is cut in advance. Since it can be configured only by attaching the flat plate 12, the C-chan 11 and the flat plate 12 can be processed separately, and the processing accuracy is improved. The bent piece 12p may be bent before the flat plate 12 is attached to the C-chan 11 or after it is attached. By adjusting the angle at which the bent piece 12p is bent, the blowing direction of the temperature-controlled air SA derived from the outlet 12h can be adjusted.

  The stud duct 10 configured as described above is supported by a mounting table 19 attached to a supporting table 18 installed on the slab SL. The support base 18 includes a floor receiver 18a that receives the flooring 15, a support bolt 18b that adjusts the floor height of the cooling / heating room R that is subject to cooling or heating (hereinafter referred to as “air conditioning”), a floor receiver 18a, And a support leg 18c for fixing the position of the support bolt 18b on the slab SL. The flooring 15 is a member that becomes a partitioning material in the floor of the air conditioning room R. The floor receiver 18 a is typically formed by processing into a quadrangular pyramid shape, and is configured such that the bottom surface of the quadrangular pyramid is in contact with the partition back surface 15 b of the flooring 15. The support leg 18c is formed with a hole through which the anchor is inserted in the edge portion, and can be fixed to the slab SL with the anchor. The support bolt 18b is formed by cutting all screws to a predetermined length that matches the floor height, one end is screwed to the top of the quadrangular pyramid of the floor support 18a, and the other end is the center of the support leg 18c. It is inserted through the part and fixed with a nut. By adjusting the degree of insertion of the support bolt 18b into the support leg 18c, the height of the floor receiver 18a, and hence the level of the flooring 15 can be adjusted. The mounting table 19 is inserted into the support bolt 18b, and its downward movement is restricted by a nut screwed into the support bolt 18b. By adjusting the height of the nut in contact with the mounting table 19, the height of the mounting table 19 and thus the level of the stud duct 10 can be adjusted.

  When installing the stud duct 10 in a building, first, the support leg 18c to which the support bolt 18b is attached is fixed on the slab SL with an anchor. The allocation of the support legs 18c is arranged in a grid pattern corresponding to the floor material 15 to be laid. Next, after a nut for supporting the mounting table 19 is screwed into the support bolt 18b, the mounting table 19 is inserted into the support bolt 18b. The level of the mounting table 19 is determined at an appropriate position by adjusting the height of the nut. Then, the stud duct 10 is mounted on the mounting table 19 so that the flat plate 12 becomes the upper surface. For this purpose, an insertion hole (not shown) for inserting the support bolt 18b is formed on the flat plate 12 and the surface of the C-chan 11 facing the flat plate 12. The insertion hole (not shown) is preferably formed before the stud duct 10 is formed (in a state where the stud duct 10 and the flat plate 12 are separated) from the viewpoint of easy processing. It is more preferable that it is formed by. When the stud duct 10 is mounted on the mounting table 19, if the bent piece 12 p of the flat plate 12 is not bent outside the C-chan 11, it is bent. Since the bent piece 12p has a role of a guide that determines the direction of the temperature-controlled air SA led out from the outlet 12h, the temperature-controlled air SA is formed at an angle that reaches as far as possible along the partition back surface 15b of the flooring 15. The angle between the bent piece 12p and the surface of the flat plate 12 may be determined so that it can be blown out. When the bent piece 12p is bent, the floor support 18a is attached to the support bolt 18b. The bent piece 12p may be bent before the stud duct 10 is mounted on the mounting table 19 or after the floor receiver 18a is attached to the support bolt 18b.

  As described above, the stud duct 10 is typically arranged at the installation interval of the support base 18 in one direction. In the case where the number of stud ducts 10 corresponding to the arrangement of the support base 18 is insufficient from the viewpoint of bringing the temperature-controlled air SA into contact with the floor material 15 uniformly, the temperature control air SA is placed on the mounting base 19 attached to the support base 18. The stud duct 10 that is not supported by the support base 18 may be installed between two adjacent stud ducts 10. In this case, the stud duct 10 may be installed using a floor band or the like that is used when performing floor rolling piping. Alternatively, all the stud ducts 10 to be installed may be fixed with a floor band or the like without using the mounting table 19. By doing so, it is not necessary to form an insertion hole (not shown) through which the support bolt 18b is inserted into the stud duct 10, so that the processing of the stud duct 10 is facilitated. On the other hand, when the stud duct 10 is mounted on the mounting table 19, the underfloor space SP between the flooring 15 and the slab SL can be secured widely and can be effectively used. In addition, it is preferable that the space | interval of the outlet 12h formed in the longitudinal direction of the stud duct 10 is also determined from a viewpoint of making the number of outlets 12h as small as possible while making the temperature control air SA uniformly contact the flooring 15.

  A forward flow chamber 25 </ b> A that distributes and supplies the temperature-controlled air SA into the stud duct 10 is connected to one end 10 a (see FIG. 2) of the stud duct 10 configured as described above. The forward flow chamber 25A is typically configured by a rectangular duct. The forward flow chamber 25A may be formed of a zinc iron plate or may be formed by processing a glass wool plate. The forward flow chamber 25 </ b> A is disposed in contact with one end 10 a of each stud duct 10. The forward flow chamber 25 </ b> A is configured such that a portion in contact with one end 10 a of each stud duct 10 is opened, and temperature-controlled air SA can be supplied from the forward flow chamber 25 </ b> A into the stud duct 10. The forward flow chamber 25 </ b> A is closed on the outer side of the stud duct 10 laid on the outermost side of one of the plurality of stud ducts 10 laid. The supply of the temperature-controlled air SA into the forward flow chamber 25A is configured to be performed from the end on the side opposite to the closed side.

  The backflow chamber 25B is typically formed of the same material as the forward flow chamber 25A in the same shape and the same length, and is connected to the other end 10b of each stud duct 10. The backflow chamber 25 </ b> B is disposed in contact with the other end 10 b of each stud duct 10. The backflow chamber 25 </ b> B is configured such that a portion that contacts the other end 10 b of each stud duct 10 is opened, and temperature-controlled air SA can be supplied from the backflow chamber 25 </ b> B into the stud duct 10. The backflow chamber 25B is closed outside the stud duct 10 laid on the outermost side opposite to the stud duct 10 closest to the end where the forward flow chamber 25A is closed. The supply of the temperature-controlled air SA into the backflow chamber 25B is configured to be performed from the end on the side opposite to the closed side. With this configuration, in the plan view, the flow direction of the temperature-controlled air SA flowing in the forward flow chamber 25A and the flow direction of the temperature-controlled air SA flowing in the reverse flow chamber 25B are reversed. ing.

  The temperature control device 21 is a device that generates the temperature control air SA adjusted to a temperature at which the radiant cooling / heating of the cooling / heating room R can be performed. The temperature control device 21 is typically a package type air conditioner, but may be an air handling unit or the like. The temperature control device 21 is installed outside the portion where the air conditioning room R is formed. The temperature control device 21 may be installed in a room adjacent to the air conditioning room R or a room away from the air conditioning room R. The temperature control device 21 may be installed at the open end of the forward flow chamber 25A and the open end of the reverse flow chamber 25B, respectively. One temperature control device 21 is installed, and the forward flow chamber 25A and the reverse flow from the temperature control device 21 are installed. A distribution duct (not shown) that guides the temperature-controlled air SA may be provided at each opening end of the chamber 25B. When a distribution duct (not shown) is provided, it is preferable to provide a damper or the like as appropriate so that the static pressures at the open end portions of the forward flow chamber 25A and the backflow chamber 25B become equal.

  When the air conditioning system 1 is constructed, the temperature control device 21 is installed before or after the stud duct 10 installed in the above-described manner is installed. When the temperature control device 21 and the stud duct 10 are installed, the forward flow chamber 25A is connected to one end 10a of each stud duct 10 and the backflow chamber 25B is connected to the other end 10b of each stud duct 10 and installed. And if necessary, a distribution duct (not shown) is installed by connecting the temperature control device 21 to each of the forward flow chamber 25A and the reverse flow chamber 25B. Thereafter, the flooring 15 is laid on the floor receiver 18a.

  Further, the floor 15 is formed with a communication port 17 (see FIG. 2) through which the temperature-controlled air SA led out from the outlet 12h of the flat plate 12 to the underfloor space SP flows into the cooling / heating room R. By introducing the temperature-controlled air SA into the cooling / heating room R through the communication port 17, it becomes possible to enjoy the cooling / heating effect by convection. The communication ports 17 are typically formed at 2 to 4 locations at the corners of the air conditioning room R. The communication port 17 is provided with a lattice (not shown) on the floor surface of the cooling / heating room R to prevent objects from falling. Furthermore, an exhaust port (not shown) through which air for the temperature-controlled air SA that has flowed into the air conditioning room R is led out of the air conditioning room R is formed on the wall surface or ceiling surface of the air conditioning room R. A return air duct (not shown) that guides the air in the air conditioning room R to the temperature control device 21 is typically connected to the exhaust port (not shown).

  With reference to FIG.1 and FIG.2 continuously, the effect | action (operation condition) of the air conditioning system 1 is demonstrated. In the temperature control device 21, the temperature-controlled air SA adjusted to a temperature suitable for radiant cooling / heating of the air conditioning room R (depending on the set temperature, for example, 18 to 23 ° C. during cooling, 30 to 35 ° C. during heating). Is generated. Radiant cooling / heating generally has a difference between the temperature of the temperature-controlled air and the temperature of the air in the heating / cooling room R, as compared with cooling / heating only by convection (cooling / heating performed by supplying temperature-controlled air to the cooling / heating room). Since it is designed to be small, less energy is required to generate the temperature-controlled air SA. The temperature-controlled air SA generated by the temperature adjustment device 21 is supplied to the forward flow chamber 25A and the reverse flow chamber 25B through a distribution duct (not shown) as necessary.

  The temperature-controlled air SA supplied to the forward flow chamber 25A and the reverse flow chamber 25B flows toward the closed end portions, and sequentially flows into the stud ducts 10 connected in order on the way. The temperature-controlled air SA that has flowed from the forward flow chamber 25A into the one end 10a of the stud duct 10 and from the back flow chamber 25B into the other end 10b of the stud duct 10 respectively enters the stud duct 10 toward the opposite end portions 10b, 10a. And is led out to the underfloor space SP from the outlet 12h that appears in order on the way. The temperature-controlled air SA flowing in from both ends 10a and 10b of the stud duct 10 meets within the stud duct 10 (hereinafter, the point where the temperature-controlled air SA meets is referred to as “meeting point”), but the end of the stud duct 10 The distance from the section to the meeting point of the temperature-controlled air SA is such that the order of the temperature-controlled air SA reaching the plurality of stud ducts 10 is reversed between the forward flow chamber 25A side and the reverse flow chamber 25B side. The distances from the end portions 10 a and 10 b to the portions having the same static pressure are different depending on the stud ducts 10, and therefore differ depending on the stud ducts 10. Since the order in which the temperature-controlled air SA reaches the plurality of stud ducts 10 is reversed between the forward flow chamber 25A side and the reverse flow chamber 25B side, the temperature distribution in the heating / cooling room R is biased to one side. Can be reduced.

  The temperature-controlled air SA derived from the outlet 12h contacts the partition back surface 15b of the floor 15 at a first predetermined angle other than 90 degrees, and diffuses along the partition back surface 15b while adjoining the stud duct. It flows toward 10. At this time, the temperature-controlled air SA flows while being in contact with the partition back surface 15b, and transmits cold (cooling) or warm (heating) to the flooring 15. Thereby, the flooring 15 is cooled or warmed. Then, cooling or heating is radiated from the cooled or warmed flooring 15 to the cooling / heating room R, and the cooling / heating of the cooling / heating room R is performed. The temperature-controlled air SA that has transmitted cold or warm heat to the flooring 15 is increased in temperature during cooling and decreased in temperature during heating. The temperature-controlled air SA existing in the underfloor space SP by exchanging heat with the flooring material 15 flows into the cooling / heating room R through the communication port 17 and convects in the cooling / heating room R. The temperature-controlled air SA flowing into the air conditioning room R is equal to the temperature of the flooring 15 or lower than the flooring 15 during cooling and higher than the flooring 15 during heating. Will contribute. The temperature-controlled air SA that has flowed into the air-conditioning room R is then returned to the temperature-adjusting device 21 and the temperature is adjusted, and then supplied to the forward flow chamber 25A and the backflow chamber 25B again, or released to the outside air to generate new air. The temperature is adjusted by the temperature control device 21 and then supplied to the forward flow chamber 25A and the reverse flow chamber 25B.

  As described above, since the cooling / heating system 1 performs radiation cooling / heating by cooling or heating the flooring 15 with the temperature-controlled air SA, the system warms the floor using a liquid as a heat medium (for example, hot water floor heating). There is no worry of problems such as water leakage that may occur. Moreover, since the manufacture of the stud duct 10 is simple because an existing material is effectively used, manufacturing and construction can be saved. In addition, most of the duct work is completed when the floor construction is completed, so that the labor (man-hours) in construction can be greatly reduced, and the system construction cost can be greatly reduced. Nevertheless, by appropriately arranging the stud duct 10 and appropriately forming the outlet 12h to the flat plate 12, the entire flooring 15 can be uniformly cooled or heated, and a good radiant cooling and heating effect can be obtained. it can.

  In the above description, the outlet 12h has a simple configuration in which the three sides of the rectangular outline 12r ruled on the flat plate 12 are cut and the bent piece 12p is bent, but the outlet 12h is blown out from the outlet 12h. In order to increase the momentum of the temperature-controlled air SA, it may be configured as follows.

  3A and 3B are views for explaining the dynamic pressure extraction member 30, where FIG. 3A is a perspective view, FIG. 3B is a side view, and FIG. 3C is a front view. The perspective view of (a) is seen from the side inserted into the stud duct 10 (see FIG. 1), and the side view of (b) shows a state in which the stud duct 10 is cut along a plane parallel to the longitudinal direction. Show. When referring to the configuration of the air conditioning system 1 in the following description, reference is made to FIG. 1 and / or FIG. 2 as appropriate. The dynamic pressure extraction member 30 includes a main body cylinder 31, a side stand plate 33, and a flange 39. The dynamic pressure extraction member 30 has a portion of the main body cylinder 31 inserted into the stud duct 10 and increases the amount of trapped temperature-controlled air SA flowing through the stud duct 10.

  The main body cylinder 31 has a hollow square cylindrical shape with one end cut obliquely, and the end face cut obliquely serves as an introduction opening face 31f for introducing the temperature-controlled air SA. An end surface cut at a right angle to the cylindrical axis on the side opposite to the introduction opening surface 31f is a nozzle outlet 31h for leading the temperature-controlled air SA. The introduction opening surface 31f is on the upstream side of the flow of the temperature-controlled air SA among the sides orthogonal to the flow direction of the temperature-controlled air SA in the stud duct 10 (which coincides with the longitudinal direction of the stud duct 10 in the present embodiment). The side is formed so as to be closer to the nozzle outlet 31 h than the downstream side, so that it is inclined with respect to the cross section perpendicular to the axis of the main body cylinder 31. The angle D formed by the cross section perpendicular to the axis of the main body cylinder 31 and the introduction opening surface 31f can be appropriately determined according to the flow rate of the temperature-controlled air SA to be taken out, but is generally between 15 degrees and 60 degrees, preferably between 30 degrees and 45 degrees. It is good to set it at an arbitrary angle. This formed angle D corresponds to a second predetermined angle. The size of the outer periphery of the main body cylinder 31 in the cross section perpendicular to the axis is formed to be slightly smaller than the outlet 12h so that it can be fitted into the outlet 12h of the flat plate 12 and the gap with the contour 12r becomes as small as possible.

  The flange 39 is provided around the nozzle outlet 31 h of the main body cylinder 31 so that the flat plate member is orthogonal to the outer surface of the main body cylinder 31. The flange 39 is provided so as to surround three sides excluding the side of the nozzle outlet 31 h corresponding to the connection side 12 s when the dynamic pressure extraction member 30 is attached to the stud duct 10. The reason why the flange 39 is removed around the side of the nozzle outlet 31h corresponding to the connection side 12s is to prevent the flange 39 from interfering with the bent piece 12p. The side standing plate 33 is erected so as to extend from two sides orthogonal to the side where the flange 39 of the nozzle outlet 31 h is not provided to the side opposite to the direction in which the main body cylinder 31 extends. In other words, when the dynamic pressure extraction member 30 is attached to the stud duct 10, the side standing plate 33 continuously extends from the surface of the main body cylinder 31 orthogonal to the flow of the temperature-controlled air SA. The side standing plate 33 may be formed integrally with the main body cylinder 31. By providing the side upright plate 33, the temperature-controlled air SA led out from the nozzle outlet 31 h is prevented from leaking in the longitudinal direction of the stud duct 10.

  In the dynamic pressure extracting member 30 configured as described above, the main body cylinder 31 is inserted from the outlet 12h of the stud duct 10 with the introduction opening surface 31f facing the flow of the temperature-controlled air SA flowing in the stud duct 10. Is done. The main body cylinder 31 is inserted, and the rod 39 stops in a state where it is placed on the flat plate 12 constituting the stud duct 10. When the dynamic pressure extracting member 30 is inserted into the outlet 12h of the flat plate 12, the bent piece 12p is once bent outward by 90 degrees or more, and after the dynamic pressure extracting member 30 is inserted, the bent piece 12p is separated from the two side walls. It is returned so as to be located between the plates 33.

  As described above, the dynamic pressure extraction member 30 attached to the stud duct 10 has a nozzle outlet 31h through the main body cylinder 31 with the introduction opening surface 31f capturing a part of the temperature-controlled air SA flowing in the stud duct 10. Therefore, the flow rate of the temperature-controlled air derived from the nozzle outlet 31h is increased and the flow velocity compared to the case where the temperature-controlled air SA is derived from the outlet 12h by static pressure without providing the dynamic pressure extraction member 30. Therefore, it is possible to increase the momentum of the temperature-controlled air SA blown out along the partition back surface 15b, thereby extending the reach of the temperature-controlled air SA, and transmitting cold or heat to a wide range of the flooring 15. It becomes possible. The dynamic pressure extraction member 30 is a member that can increase the dynamic pressure of the temperature-controlled air SA derived from the outlet 12h (nozzle outlet 31h) as compared to the case where the dynamic pressure extraction member 30 is not provided. However, it does not necessarily mean that it is a member that extracts only dynamic pressure.

  FIG. 4 is a diagram for explaining a total pressure extraction member 40 for increasing the momentum of the temperature-controlled air SA blown from the outlet 12h, which is different from the dynamic pressure extraction member 30 (see FIG. 3). (a) is a perspective view, (b) is a side view, and (c) is a front view. The perspective view of (a) is seen from the side inserted into the stud duct 10 (see FIG. 1), and the side view of (b) shows a state in which the stud duct 10 is cut along a plane parallel to the longitudinal direction. Show. When referring to the configuration of the air conditioning system 1 in the following description, reference is made to FIG. 1 and / or FIG. 2 as appropriate. The total pressure extraction member 40 includes a main body cylinder 41, a side stand plate 43, and a flange 49. The total pressure extraction member 40 is a member in which a portion of the main body cylinder 41 is inserted into the stud duct 10 from the outlet 12 h of the flat plate 12 and extracts the total pressure of the temperature-controlled air SA flowing in the stud duct 10. Below, it demonstrates on the premise of the state attached to the stud duct 10. FIG.

  The main body cylinder 41 is formed in a generally hollow square cylinder, and a total pressure nozzle outlet 41h for leading out the temperature-controlled air SA is formed on one end face. Around the total pressure nozzle outlet 41h, the side standing plate 43 and the flange 49 are the same as the side standing plate 33 and the flange 39 provided around the nozzle outlet 31h of the dynamic pressure extraction member 30 (see FIG. 3). It is provided. Therefore, when the main body cylinder 41 is inserted from the outlet 12 h of the stud duct 10, the collar 49 stops in a state where it is placed on the flat plate 12 constituting the stud duct 10. When the total pressure extracting member 40 is inserted into the outlet 12h of the flat plate 12, the bent piece 12p is once bent outward by 90 degrees or more, and after the total pressure extracting member 40 is inserted, two bent pieces 12p are provided. Returning so as to be positioned between the side standing plates 43 is the same as when attaching the dynamic pressure extraction member 30 (see FIG. 3). Further, the size of the outer periphery of the main body cylinder 41 in the cross section perpendicular to the axis is formed in the same manner as the main body cylinder 31 of the dynamic pressure extraction member 30 (see FIG. 3).

  The main body cylinder 41 is divided into two parts by attaching a flat partition plate 42 in a direction parallel to the side standing plate 43. The main body cylinder 41 is partitioned by an intermediate partition plate 42, thereby forming a dynamic pressure channel 41ra as a first gas channel and a static pressure channel 41rb as a second gas channel. That is, the gas flow path 41r of the total pressure extraction member 40 includes a dynamic pressure flow path 41ra and a static pressure flow path 41rb. As a result, the total pressure nozzle outlet 41h is also divided into a dynamic pressure outlet 41ha that is the end of the dynamic pressure channel 41ra and a static pressure outlet 41hb that is the end of the static pressure channel 41rb. The dynamic pressure channel 41ra is formed on the upstream side in the flow direction of the temperature-controlled air SA, and the static pressure channel 41rb is formed on the downstream side.

  The surface of the main body cylinder 41 facing the flow direction of the temperature-controlled air SA (the surface of the main body cylinder 41 connected to the side stand plate 43 on the upstream side of the flow direction of the temperature-controlled air SA, and corresponds to the first introduction opening surface. ) Is formed with a dynamic pressure inlet 41fa for introducing the temperature-controlled air SA into the dynamic pressure flow path 41ra. Other than this surface, no introduction port for introducing the temperature-controlled air SA into the dynamic pressure flow path 41ra is formed. The surface of the main body cylinder 41 on the downstream side in the flow direction of the temperature-controlled air SA (the surface of the main body cylinder 41 connected to the side standing plate 43 on the downstream side in the flow direction of the temperature-controlled air SA, and corresponds to the second introduction opening surface. ) Is formed with a static pressure introduction port 41fb for introducing the temperature-controlled air SA into the static pressure channel 41rb. The static pressure introduction port 41fb does not communicate with the dynamic pressure flow path 41ra.

  The operation when the above-described total pressure extracting member 40 is attached to the stud duct 10 is as follows. The temperature-controlled air SA flowing inside the stud duct 10 is taken into the dynamic pressure flow passage 41ra and collides with the dynamic pressure introduction port 41fa and flows toward the dynamic pressure outlet 41ha. On the other hand, the temperature-controlled air SA that has not been taken in from the dynamic pressure introduction port 41fa continues to flow through the stud duct 10 and is partially static due to the static pressure of the temperature-controlled air SA when passing by the side of the static pressure introduction port 41fb. It flows into the static pressure channel 41rb from the pressure inlet 41fb and flows toward the static pressure outlet 41hb. The temperature-controlled air SA derived from the dynamic pressure outlet 41ha and the temperature-controlled air SA derived from the static pressure outlet 41hb are mixed when being guided by the bent piece 12p toward the partition back surface 15b, After reaching the back surface 15b, it flows along the partition back surface 15b. The temperature-controlled air SA flowing along the partition back surface 15b is obtained by taking out both the dynamic pressure and the static pressure of the temperature-controlled air SA flowing through the stud duct 10, that is, the total pressure. Thus, the temperature-controlled air SA derived from the total pressure nozzle outlet 41h (the dynamic pressure outlet 41ha and the static pressure outlet 41hb) of the total pressure extraction member 40 is derived when the total pressure extraction member 40 is not provided. The flow rate is faster than that of the temperature-controlled air SA, and the momentum of the temperature-controlled air SA blown out along the partition back surface 15b can be increased. It becomes possible to transmit cold or warm heat over a wide range.

  In the above description, the temperature-controlled air SA is supplied to the stud duct 10 from the forward flow chamber 25A and the reverse flow chamber 25B formed by the duct. However, the end portion of the underfloor space SP is partitioned to form an underfloor chamber (not shown). ), The stud duct 10 may be connected to the underfloor chamber (not shown), and the temperature-controlled air SA may be supplied to the stud duct 10 from the underfloor chamber.

  In the above description, the floor material 15 to be cooled or heated is provided on the floor surface of the air conditioning room R. However, the ceiling and / or the wall may be configured to be cooled or heated by the temperature-controlled air SA. Good. When adopting the ceiling, for example, the stud duct 10 can be configured by being connected to a forward flow chamber 25A and a reverse flow chamber 25B provided adjacent to the beam. Moreover, when employ | adopting as a wall, it can comprise, for example by connecting the stud duct 10 to the forward flow chamber 25A and the backflow chamber 25B which were provided upright at predetermined intervals. Also in the case of adopting the ceiling and / or the wall, a ceiling chamber or an in-wall chamber may be employed instead of the forward flow chamber 25A and the reverse flow chamber 25B.

  In the above description, the temperature-controlled air SA released to the underfloor space SP is allowed to flow into the cooling / heating room R through the communication port 17, but may be discharged to the outside from the underfloor space SP, or the underfloor space. You may return air from SP to the temperature control apparatus 21 via a duct.
