  For example, in the following Patent Document 1, a lower space portion connected to an indoor space (indoor space) is provided at a lower portion of a storage shelf, and a blowout port that blows out conditioned air generated by an air conditioner that air-conditions a building includes the lower portion. The technique provided in the floor part of the space part is disclosed. Moreover, in this prior art, the movable shelf board which comprises the upper part of a lower space part is provided in the lower part of the storage shelf, and the conditioned air sent out from the blower outlet hits the movable shelf board, changes its direction, and is indoors. Guided to the space side.

JP 2012-176001 A

  In the above prior art, the air-conditioning duct through which the air-conditioned air flows and the air outlet are directly connected, and the air-conditioned air blown out from the air outlet directly hits the movable shelf so that the direction of the air-conditioned air is A smooth flow cannot be obtained, pressure loss occurs, and air conditioning efficiency is not good.

  An object of the present invention is to obtain an air conditioning facility and a whole building air conditioning system capable of improving the air conditioning efficiency in consideration of the above facts.

  According to a first aspect for achieving the above object, in an air conditioner, a lower space section that is provided below a storage space of a storage section disposed in an indoor space and is partitioned from the indoor space, and an underfloor space An air-conditioning duct that connects the air-conditioning apparatus for air-conditioning the building and the lower space part and through which the air-conditioned air generated by the air-conditioning apparatus flows, and a blow-out chamber that is arranged in the lower space part and connected to the air-conditioning duct And a blow grill provided in a wall portion constituting the lower space portion and connected to the blow chamber to guide the conditioned air to the indoor space.

  In the first aspect, in the air conditioning equipment, a storage section is disposed in the indoor space, and a lower space section partitioned from the indoor space is provided below the storage space of the storage section. On the other hand, an air conditioning duct is disposed in the underfloor space. The air-conditioning duct connects an air-conditioning apparatus that air-conditions the building and a lower space of the storage unit, and air-conditioned air generated by the air-conditioning apparatus flows through the air-conditioning duct.

  Here, the blowout chamber arrange | positioned in the lower space part is connected to the air-conditioning duct. A blow grill is connected to the blow chamber, and conditioned air flowing in the air conditioning duct is guided to the indoor space through the blow chamber and the blow grill. The blow-out grill is provided on a wall portion constituting the lower space portion. That is, the blowing grill is provided on a vertical plane orthogonal to the floor surface.

  For this reason, even if dust adheres to the surface of the blowing grill, the dust is likely to fall. Therefore, compared with the case where the blowing grill is provided on the floor surface, it is difficult for dust to adhere to the surface of the blowing grill. Therefore, it is possible to suppress a decrease in pressure loss due to dust adhering to the surface of the blowout grill.

  By the way, when the blowout grill is directly connected to the air conditioning duct, if the flow passage cross-sectional areas are greatly different between the blowout grill and the air conditioning duct, the air conditioning efficiency and the like are affected. For example, when reducing the difference in the channel cross-sectional area between the two, the channel cross-sectional area of the blowout grill should be reduced according to the air conditioning duct, or It is possible to increase the area. In the former case, the flow rate of the conditioned air sent from the flow channel grill to the indoor space is increased by the reduction in the flow passage cross-sectional area of the blowout grill. In the latter case, the flow rate of the air conditioning duct is interrupted. As the area increases, the space under the floor becomes narrower.

  In the present invention, a blowout chamber is interposed between the air conditioning duct and the blowout grill. For this reason, the difference in flow path cross-sectional area generated between the air-conditioning duct and the blow-out grill can be absorbed by the blow-out chamber, thereby reducing the pressure loss due to the difference in flow-path cross-sectional area between the air-conditioning duct and the blow-out grill. Can be suppressed.

  In addition, about the "lower space part" in this invention, you may be made into the area | region contained in a storage part, and may be set as the area | region different from a storage part. That is, it can be set to any one according to the explanation.

  According to a second aspect, in the first aspect, a working space portion is provided in the lower space portion next to the blowing chamber.

  In the second aspect, since a work space is provided next to the blowout chamber in the lower space of the storage portion, the work space can be secured when installing the air conditioning duct and the blowout chamber. High nature.

  According to a third aspect, in the first aspect or the second aspect, the flow passage cross-sectional area on the downstream side along the direction in which the conditioned air flows in the blowout chamber is larger than the flow passage cross-sectional area of the air-conditioning duct. It is formed to become.

  In the third aspect, the blowout chamber is formed such that the flow path cross-sectional area on the downstream side (outlet side) is larger than the flow path cross-sectional area on the upstream side (inlet side) along the direction in which the conditioned air flows. Yes. The inlet side of the blowing chamber is connected to the air conditioning duct, and the outlet side of the blowing chamber is connected to the blowing grill. For this reason, the conditioned air sent from the air conditioning duct can be sent as a gentle wind to the indoor space via the blowout chamber and the blowout grill.

  A 4th aspect is provided with the air-conditioning installation in any one of a 1st aspect-a 3rd aspect in a whole building air conditioning system.

  In the 4th mode, in the whole building air-conditioning system, the operation and effect obtained in the 1st mode-the 3rd mode are produced.

  As described above, the present invention has an excellent effect of suppressing the decrease in pressure loss and improving the air conditioning efficiency.

That is, the storage portion 26 is a so-called double door 28, and the storage space 30 is opened by opening the door 28. The storage space 30 is divided into a plurality of interiors by a shelf board 32 and the like.

  In the present embodiment, a lower space 34 is provided below the storage space 30. The lower space 34 may be a region included in the storage unit 26 or may be a region different from the storage unit, and can be set to any one according to the description.

  Specifically, when the lower space portion 34 is an area included in the storage portion 26, the storage portion 26 is provided in the living room 12, and the storage portion 26 includes the storage space 30 and the lower space portion 34. It is configured to include. On the other hand, when the lower space 34 is a different area from the storage 26, the storage 12 and the lower space 34 are provided in the living room 12. In the present embodiment, the lower space part 34 will be described as an area included in the storage part 26.

  As shown in FIG. 3, in the lower space portion 34 constituting the lower portion of the storage portion 26, a pair of base materials 36 (along the vertical direction at both ends in the width direction of the lower space portion 34 on the living room 12 side. So-called vertical bars are arranged. Under the upper and lower ends of the pair of base materials 36, base materials 38 and 39 (so-called horizontal rails) are bridged along the horizontal direction. Further, between the base material 38 and the base material 39, a base material 40 (so-called horizontal rail) is bridged between the pair of base materials 36 along the horizontal direction. Between the base material 40 and the base material 38, a base material 41 (a so-called vertical beam) is bridged along the vertical direction inside a pair of base materials 36 along the width direction of the lower space 34. Yes.

  In the lower space portion 34, work space portions 46 and 48 are provided on both sides of the blowout chamber 42 and the air conditioning duct 20, respectively. The work space portions 46 and 48 are set so as to be secured as a workable space when performing installation, maintenance, and the like of a blowout chamber 42 and a blowout grill 44 described later. Here, the base material 40, which is a horizontal beam, is given priority over the base material 41, which is a vertical beam. Thereby, it is possible to secure a sufficient working space so that the space adjacent to the blowout chamber 42 and the air conditioning duct 20 is not blocked by the crosspiece.

  A rectangular opening 52 is formed by the base materials 38, 40, and 41. Further, the base materials 36, 38, 39, 40, 41 each have a prismatic shape, and a gypsum board 54 (see FIG. 2) is attached to the surface. Then, the lower space 34 is separated from the living room 12 by pasting the gypsum board 54 on the base materials 36, 38, 39, 40, 41 except for the opening 52.

  On the other hand, as shown in FIG. 2, communication ports 58 and 60 penetrate through the floor portion 56 and the lower wall 34 </ b> A of the storage portion 26 (lower space portion 34), respectively. The space 22 and the lower space 34 can communicate with each other. The air conditioning duct 20 is inserted through the communication ports 58 and 60, and a seal member (not shown) is provided on the outer periphery of the air conditioning duct 20. The space between the air conditioning duct 20 and the communication ports 58 and 60 is sealed by this sealing member.

  The air conditioning duct 20 is disposed so as to rise upward in the lower space portion 34, and a blowout chamber 42 is connected to the distal end portion 20 </ b> A of the air conditioning duct 20. As shown in FIG. 4, the blowing chamber 42 has a substantially pentagonal shape in plan view, and includes a casing 62 and a frame 64. The casing 62 is connected to the air conditioning duct 20, and a blow grill 44 described later is connected to the frame 64.

  Here, the casing 62 includes a connection portion 66 having a substantially triangular shape in a plan view and a horizontal portion 68 having a substantially rectangular shape in a plan view. A duct connection port 70 passes through a central portion of the lower wall 66A of the connection portion 66. A cylindrical duct connection collar 72 is suspended from the duct connection port 70, and the distal end portion 20 </ b> A of the air conditioning duct 20 is connected to the duct connection collar 72. Thereby, the conditioned air in the air conditioning duct 20 is guided into the casing 62 through the connection portion 66 of the casing 62.

  The flow passage cross-sectional area of the connection portion 66 of the casing 62 is formed to be larger than the flow passage cross-sectional area of the air conditioning duct 20. Further, since the air conditioning duct 20 is arranged so as to stand up in the lower space portion 34, the conditioned air sent from the front end portion 20 </ b> A of the air conditioning duct 20 moves upward from the duct connection port 70 in the connection portion 66 of the casing 62. Will be sent out. However, as described above, the flow path cross-sectional area of the connecting portion 66 of the casing 62 is formed to be larger than the flow path cross-sectional area of the air conditioning duct 20, so that the conditioned air sent from the air conditioning duct 20 The flow rate is slow. The conditioned air sent into the connecting portion 66 of the casing 62 is guided along the horizontal direction from the connecting portion 66 through the horizontal portion 68.

  On the other hand, the frame 64 is formed continuously with the horizontal portion 68 of the casing 62, and each flow path has a substantially rectangular shape. Further, the blowing grill 44 can be connected to the frame 64. As shown in FIG. 4, the blow-out grill 44 has a rectangular shape when viewed from the front, and includes a grill portion 76 and a fitting portion 78. The fitting portion 78 has a substantially rectangular shape when viewed from the back. It is made.

  As shown in FIG. 2, the blowing grill 44 is attached to a gypsum board 54 that divides the lower space 34 provided in the storage portion 26 and the living room 12. Specifically, as shown in FIGS. 2 and 3, the gypsum board 54 is affixed to the base materials 36, 38, 39, 40, 41 except for the openings 52 formed by the base materials 38, 40, 41. Therefore, a mounting hole 74 for mounting the blowing grill 44 is formed in the gypsum board 54. As shown in FIG. 4, the mounting hole 74 has a substantially rectangular shape in accordance with the shape of the fitting portion 78 of the blowing grill 44, and the fitting portion 78 can be fitted into the mounting hole 74. ing. A seal member (not shown) is provided on the outer periphery of the fitting portion 78, and the gap between the fitting portion 78 and the mounting hole 74 is sealed by the seal member.

  The fitting portion 78 can be fitted into the frame 64 of the blowing chamber 42, and the blowing grill 44 is connected to the blowing chamber 42 in a state where the fitting portion 78 is fitted into the frame 64. . In addition, between the fitting part 78 and the flame | frame 64 is sealed by the sealing member which is not shown in the state where the blowing grill 44 was connected to the blowing chamber 42.

  On the other hand, the grill portion 76 has a lattice shape including the vertical ribs 80 and the horizontal ribs 82, and the vertical ribs 80 are provided on the design surface side (the living room 12 side). 78 side) is provided with a lateral rib 82. Further, on the fitting portion 78 side of the grill portion 76, bearing portions (not shown) are respectively provided above and below the both ends in the longitudinal direction.

  A long plate-like flap 84 whose longitudinal direction is the horizontal direction can be supported on the bearing portion. From both ends in the longitudinal direction of the flap 84, shaft portions 86 project along the longitudinal direction of the flap 84, and the flap portions are supported via the shaft portion 86 in a state where these shaft portions 86 are supported by the bearing portions. 84 is rotatable along the vertical direction around the bearing portion. In addition, the angle of the flap 84 is set with respect to the floor portion 56 (see FIG. 2) in the living room 12 in advance.

  Further, the shaft portion 86 is provided with a dial portion 88 that interlocks with the shaft portion 86, and the flap 84 is rotated via the shaft portion 86 by rotating the dial portion 88. . In the present embodiment, the dial portion 88 can be operated by removing the grill portion 76, but the dial portion 88 may be operable from the living room 12 side.

(Operation and effect of air conditioning equipment)
Next, the effect | action and effect of the air conditioning equipment 10 which concern on this Embodiment are demonstrated. As shown in FIG. 1 and FIG. 2, in the present embodiment, a storage unit 26 having a storage space 30 is arranged in the living room 12, and the living room 12 is partitioned below the storage space 30. A lower space 34 is provided.

  In this lower space part 34, the air conditioning duct 20 connected to the air conditioner 18 passes through the floor 56 and the lower wall 34A of the storage part 26 (lower space part 34) and rises upward. A blowout chamber 42 is connected to the front end 20A of the air conditioning duct 20. A blow grill 44 is connected to the blow chamber 42, and conditioned air flowing through the air conditioning duct 20 is guided into the living room 12 through the blow chamber 42 and the blow grill 44.

  Here, the blowing grill 44 is provided on a gypsum board 54 constituting the lower space 34 provided in the storage unit 26. That is, the blowing grill 44 is provided on the vertical surface 90 orthogonal to the floor surface 56A. For this reason, even if dust adheres to the surface of the grill part 76 which comprises the said blowing grill 44, the possibility that the dust will fall is high.

  Therefore, although not shown, in the present embodiment, it is difficult for dust to adhere to the surface of the grill portion 76 of the blowing grill 44 shown in FIGS. 1 and 2 as compared with the case where the blowing grill is provided on the floor surface. For this reason, it is possible to suppress a decrease in pressure loss due to dust adhering to the surface of the grill portion 76 of the blowing grill 44. And by providing the air-conditioning duct 20 and the blowing chamber 42 in the lower space part 34, airtightness and heat insulation can be maintained stably.

  Although not shown, when the blowout grill is provided on the floor surface, in order to open the top of the blowout grill, do not provide a member that blocks the blowout grill on the floor surface. A design such as avoiding the arrangement of the blowing grill on the floor surface is performed. In addition to this, there are cases where design restrictions are imposed, such as that a blow grill cannot be provided in a narrow space such as a laundry room or between the floors of a Japanese-style room.

  However, in the present embodiment, the blow-out grill 44 is provided on the gypsum board 54 constituting the lower space 34 of the storage unit 26 and is provided on the vertical surface 90 orthogonal to the floor surface 56A. Such a problem does not occur. Therefore, the degree of design freedom is higher than in the prior art, and the number of building variations can be increased. That is, conditioned air can be sent out in the entire space portion 14 including a narrow space such as a laundry room.

  Although not shown, when the blow-out grill is directly connected to the air-conditioning duct, if the cross-sectional areas of the blow-off grill and the air-conditioning duct are greatly different, the air-conditioning efficiency is affected. In general, in the underfloor space, a heat insulating material is accommodated or electrical wiring is performed, so that the outer diameter of the air conditioning duct is formed to be as small as possible. On the other hand, in the blow-out grill, in order to send a gentle wind as much as possible, the cross-sectional area of the flow path is preferably as large as possible without causing a problem from the viewpoint of design.

  For this reason, for example, when reducing the difference in flow path cross-sectional area between the air conditioning duct and the blowout grill, the flow passage cross-sectional area of the blowout grill is reduced according to the air conditioning duct, In addition, it is conceivable to increase the cross-sectional area of the air conditioning duct. In the former case, the flow rate of the conditioned air sent from the flow channel grill to the indoor space is increased by the reduction in the flow rate cross sectional area of the blowout grill. In the latter case, the flow rate cross sectional area of the air conditioning duct is reduced. The space in the underfloor space becomes narrower as the size is increased.

  However, in the present embodiment, as shown in FIGS. 2 and 3, the blowout chamber 42 is interposed between the air conditioning duct 20 and the blowout grill 44. For this reason, the blowout chamber 42 can absorb the difference in flow path cross-sectional area that occurs between the air conditioning duct 20 and the blowout grill 44.

  Here, in the present embodiment, the casing 62 includes a connection portion 66 having a substantially triangular shape in plan view and a horizontal portion 68 having a substantially rectangular shape in plan view. And in the blowing chamber 42, it forms so that a flow-path cross-sectional area may become large gradually toward the downstream (horizontal part 68) from the upstream (connection part 66) along the direction through which conditioned air flows. Thereby, even if a difference occurs in the cross-sectional area of the flow path between the air conditioning duct 20 and the blowing grill 44, the difference can be absorbed by the blowing chamber 42, and a decrease in pressure loss can be suppressed. Air conditioning efficiency can be improved.

  In the present embodiment, the flow passage cross-sectional area of the blowout chamber 42 is formed to be larger than the flow passage cross-sectional area of the air conditioning duct 20, and the blowout chamber 42 is connected to the blowout grill 44. The conditioned air sent from 20 can be sent to the living room 12 as a gentle wind through the blowout chamber 42 and the blowout grill 44.

  Further, in the present embodiment, as shown in FIG. 3, working space portions 46 and 48 are respectively provided on both sides of the blowing chamber 42 in the lower space portion 34 of the storage portion 26. For this reason, when installing and maintaining the air-conditioning duct 20 and the blowout chamber 42, a work space can be secured and the workability is high. The work space portions 46 and 48 may be any size as long as the work can be performed. For this reason, for example, the work space portions 46 and 48 may be provided only in the upper portion of the lower space portion 34. Further, only one of the work space portions 46 and 48 may be provided.

  In the present embodiment described above, an example in which a so-called whole-building air conditioning system 11 in which conditioned air is sent out by the air conditioner 18 in all the space portions 14 among the plurality of space portions 14 provided in the building is introduced. However, the entire building is not necessarily required, and may be applied to a part of the plurality of space portions 14.

  Furthermore, although one embodiment of the present invention has been described here, the present invention is not limited to such an embodiment, and one embodiment and various modifications may be combined as appropriate. Of course, various embodiments can be implemented without departing from the scope of the invention.
