Description

  The present invention relates to an air conditioner installed in a building.

As this type of air conditioning equipment, a technique has been proposed in which an air flow path is configured between a first floor portion and a second floor portion of a building, and air is blown using the air flow path (for example, Patent Documents). 1). Specifically, in a multi-story building, a ceiling provided between the living room and the floor directly above forms a sealed area sealed from the outside, and air flows into the ceiling from the sealed area to the living room. It is set as the structure which forms the blower outlet to be made. That is, a sealed area is formed between the ceiling of the living room and the floor on the upper floor, and the sealed area is used as an air flow path.
JP-A-11-304190

  However, in the above-described conventional technology, the sealed area must be partitioned according to a room to be air-conditioned, in other words, according to a plurality of air-conditioning ranges set on the same floor. In such a case, it is necessary to provide partition members for each air-conditioning range, and to block these partition regions in an airtight state. Therefore, there arises a disadvantage that the construction becomes complicated in installing the air conditioning equipment.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, an embodiment of the invention will be described with reference to the drawings. In this embodiment, it is embodied in a two-story unit type building constructed by a steel unit construction method, and an outline of the unit type building 10 is shown in FIG. The unit type building 10 includes a building main body 11 formed by combining a plurality of building units 20 and a roof 12 disposed above the building main body 11. In addition, the building unit 20 used for the unit type building 10 is manufactured in advance in a factory, and then transported to a building site by a truck or the like.

  FIG. 6 is a perspective view showing the configuration of the building unit 20. In the building unit 20, columns 21 are arranged at the four corners, and the upper end and the lower end of each column 21 are connected by four ceiling beams 22 and floor beams 23, respectively. A rectangular frame (frame) is formed by the pillars 21, the ceiling beams 22 and the floor beams 23. The column 21 is made of a square tube-shaped square steel. Moreover, the ceiling beam 22 and the floor beam 23 are made of channel steel having a U-shaped cross section, and are installed so that the openings thereof face each other. The ceiling large beam 22 (specifically, a grooved steel web) is provided with beam through holes 22a having a diameter of about 100 mm at a plurality of locations.

  A plurality of small ceiling beams 25 are bridged between the large ceiling beams 22 on the long sides of the building unit 20 at predetermined intervals. Similarly, a plurality of floor beams 26 are bridged between the large floor beams 23 on the long sides of the building unit 20 at predetermined intervals. The ceiling beam 25 and the floor beam 26 are horizontally provided at the same interval and at positions corresponding to the top and bottom. Although illustration is omitted, the ceiling surface material is supported by the ceiling beam 25 and the floor material is supported by the floor beam 26.

  The unit building 10 of the present embodiment employs a whole building air conditioning system, and air conditioning indoor units are installed as air conditioning facilities in the ceiling back spaces on the first floor and the second floor, and branch off from the air conditioning indoor unit. A plurality of duct members extending in the direction are installed. In the present embodiment, in particular, the air conditioning duct member is configured as a flat air conditioning chamber that is expanded horizontally in the ceiling space, and an air flow path is formed using the air conditioning chamber. . Hereinafter, the air conditioning equipment of this air conditioning system will be described in detail.

  Here, the air conditioning facilities in the first floor ceiling back space and the second floor ceiling back space are substantially the same, and the configuration of the air conditioning facilities is shown in FIGS. 1 and 2. FIG. 1 is a plan view showing a configuration of air conditioning equipment in a building ceiling (for example, the first floor ceiling), and FIG. 2 is a longitudinal sectional view of the air conditioning equipment. 2 corresponds to a cross-sectional view taken along the line AA in FIG. 1. For convenience of explanation, FIG. 2 also shows a part of the building unit 20 on the second floor, and also includes the ceiling material 27 and the floor material 28. Show.

  In FIG. 1, a plurality (six in the figure) of building units 20 are connected in a state where the columns 21 are close to each other, and the adjacent building units 20 have ceilings on the long side (girder side). The large beams 22 are arranged facing each other, and the ceiling large beams 22 on the respective short sides (face side) are arranged facing each other. In this case, the ceiling back space is partitioned for each unit by the ceiling beam 22.

  And in the structure of illustration, the thin flat air conditioning chamber 31 is installed on the ceiling beam 25 of five building units 20 among all six. Here, at the boundary between the lower floor side building unit 20 and the upper floor side building unit 20, as shown in FIG. 2, there is a gap between the lower floor side ceiling material 27 and the upper floor side floor material 28. An inter-story space K is formed in the air-conditioner, and the air-conditioning chamber 31 is installed using the inter-story space K. More specifically, an air conditioning chamber 31 is installed in a space between the ceiling beam 25 of the lower floor unit and the floor beam 26 of the upper floor unit.

  All of the air conditioning chambers 31 have the same basic structure and have substantially the same planar shape (that is, a rectangular shape) as the building unit 20. Moreover, the size (size) of each chamber 31 is also the same. For details on the chamber size, the air-conditioning chamber 31 has vertical and horizontal dimensions D1 and D2 (see FIG. 1) somewhat smaller than the rectangular portion surrounded by the ceiling beams 22 on the four sides in the building unit 20, and its height. The dimension H (see FIG. 2) is slightly smaller than the gap dimension between the ceiling beam 25 of the lower floor building unit 20 and the floor beam 26 of the upper floor building unit 20. . As a result, the air conditioning chamber 31 can be installed in the area partitioned by the ceiling beam 22 for each building unit 20. In the case where a vibration reducing device (dynamic damper) is provided on the floor beam 26 for the purpose of reducing floor vibration and improving sound insulation, the air conditioning chamber 31 takes into account the installation space of the signal reducing device. The size of

  The air conditioning chambers 31 are connected to each other by a plurality of connection ducts 32 provided for each chamber, and the conditioned air can be circulated between the chambers through the connection ducts 32. In this case, the interstory space K (ceiling back space) is partitioned by the ceiling beam 22 for each building unit 20, and is connected through the beam through hole 22 a (see FIG. 6) formed in the ceiling beam 22. A duct 32 is installed. The connection duct 32 is configured by flexible piping, and the diameter thereof is substantially equal to the diameter of the beam through hole 22a (about 100 mm).

  Each of the air conditioning chambers 31 has an opening 31a formed on the lower surface thereof, and a blow grill 33 is provided in the opening 31a. Air-conditioned air fed from a fan device 34 serving as an indoor air conditioner is introduced into the air-conditioning chamber 31 of each unit 20 and then blown out into the room from the outlet of the outlet grill 33.

  The blowing grill 33 may not be provided in all the air conditioning chambers 31, and there may be an air conditioning chamber 31 in which the blowing grill 33 is not provided. For example, when the same space (one room) is comprised by the two building units 20, the structure by which the blowing grill 33 is provided only in one air-conditioning chamber 31 on the back of the ceiling may be sufficient. In FIG. 1, the blow grill 33 is not provided in the air conditioning chamber 31 of the building unit 20 shown in the upper right.

  Next, a more detailed configuration of the air conditioning chamber 31 will be described. FIG. 3A is a perspective view of the air conditioning chamber 31, and FIG. 3B is a cross-sectional view of the air conditioning chamber 31.

  The air conditioning chamber 31 is configured by combining a plurality of plate materials made of a highly airtight and heat insulating material such as high-density glass wool in a rectangular parallelepiped shape, and a chamber chamber C is formed therein. In this case, the plate material that forms the upper and lower plate portions and the plate material that forms the side plate portion having a generally rectangular shape are joined together by bonding or the like. Alternatively, an adhesive tape (aluminum tape or the like) may be attached to the joint portion to improve the air tightness at the joint portion. In addition, it is also possible to use the board | plate material which consists of a vacuum heat insulating material, a polystyrene foam, a polyurethane foam (foaming-type heat insulating material), polyethylene etc. as a material of a board | plate material.

  The side plate portion of the air conditioning chamber 31 is provided with through holes 31b at a plurality of locations, and the connection ducts 32 are connected to the through holes 31b, respectively.

  Here, when the pressure in the chamber C changes, it is conceivable that the air conditioning chamber 31 is deformed along with the pressure change. For example, when the pressure in the chamber C becomes positive, the central portion of the air conditioning chamber 31 is bent and deformed. It is also conceivable that the upper and lower plate portions are bent and deformed by the weight of the plate material.

  Therefore, in this embodiment, the deformation preventing member 36 is provided between the upper plate portion and the lower plate portion constituting the air conditioning chamber 31. The deformation preventing member 36 includes a rod 36a penetrating the upper plate portion and the lower plate portion of the air conditioning chamber 31, and fixtures 36b, 36c, 36d for fixing the rod 36a to the upper and lower plate portions. The prevention member 36 suppresses bending deformation accompanying expansion or contraction of the air conditioning chamber 31 and bending deformation due to its own weight. The deformation preventing member 36 is preferably provided at one or a plurality of locations (two locations in FIG. 3) near the center of the air conditioning chamber 31.

  The air conditioning chamber 31 is attached to the unit 20 when the building unit 20 is manufactured in a factory. Specifically, the air conditioning chamber 31 is placed on the ceiling beam 25 of the building unit 20, and in this state, the air conditioning chamber 31 is fixed by a fixing band or the like. Therefore, when the building unit 20 manufactured in the factory is transported to the construction site, the air conditioning chamber 31 is transported integrally with the unit 20.

  Here, when installing the air conditioning chamber 31 in the factory, an opening 31a is formed in the air conditioning chamber 31 in accordance with the position of the air outlet of each unit. At this time, the opening 31a can be formed at an arbitrary position on the lower surface portion of the air conditioning chamber 31, and the opening 31a can be formed at a different position for each unit to set the outlet position. In addition, in accordance with the formation of the opening 31 a of the air conditioning chamber 31, an opening is also formed in the ceiling material 27, and the blowing grill 33 is attached to the opening. However, the operation of forming the opening 31a in the air conditioning chamber 31, the operation of forming the opening in the ceiling material 27, and the mounting operation of the blowing grill 33 are performed at the building site after the building unit 20 is transported to the building site. It may be broken.

  And in a construction site, with each building unit 20 being assembled, the chamber 31 for air conditioning will be arrange | positioned in a predetermined position. At this time, the sealing work is not forced for each floor space of each unit, and the air-conditioning equipment can be installed relatively easily. At the construction site, the connecting ducts extending from the air conditioning chamber 31 of each unit are connected using an adhesive tape or the like.

  Incidentally, when the connection duct 32 is not connected to the air conditioning chamber 31 in advance, the connection duct 32 is inserted into the beam through-hole 22a and the connection duct 32 between the two air conditioning chambers 31 at the construction site. Is connected.

  As described above, by using the air conditioning chamber 31 as a duct member for air conditioning, the pressure loss at the time of air blowing is greatly reduced. Details thereof will be described with reference to FIG. In FIG. 4, (a) is a schematic diagram showing the air conditioning equipment of the present embodiment, and (b) is a schematic diagram showing a conventional air conditioning equipment composed of air conditioning piping such as a circular duct as a comparison object. It is.

  In the conventional configuration shown in FIG. 4B, the air-conditioning duct member is constituted by an air-conditioning pipe 39 such as a circular duct, and the outer diameter of the pipe 39 is formed on the beam material of the building unit. The size is limited to the diameter of the beam through hole. In such a configuration, a large pressure loss occurs when the conditioned air flows in the air conditioning pipe 39. This pressure loss is caused by the straight pipe resistance in the straight pipe portion of the air-conditioning pipe 39 or the local resistance in the bent portion. Therefore, the air volumes V11, V12, V13 [m3 / h] at the outlets for each building unit are different, and in the illustrated example, V11 << V12 << V13. That is, a sufficient air volume cannot be secured at the outlet having a long flow path length from the fan device 34 (indoor air conditioner). Moreover, the power loss of the fan apparatus 34 also becomes large and energy efficiency falls.

  On the other hand, in the configuration of the present embodiment shown in FIG. 4A, by providing the air conditioning chamber 31 for each building unit, the straight pipe resistance in the straight pipe portion of the air conditioning pipe and the local resistance in the bent portion are reduced. The resulting pressure loss is greatly reduced. In other words, in this configuration, the pressure in the same chamber is substantially equal in any part. Therefore, the air volumes V1, V2, and V3 [m3 / h] at the outlets for each building unit are substantially the same (V1≈V2≈V3). That is, a sufficient air volume can be ensured even at the outlet having a long flow path length from the fan device 34. Further, the power loss of the fan device 34 is minimized, and the energy efficiency can be increased.

  Note that a connection duct 32 is provided between the plurality of air conditioning chambers 31, and pressure loss due to sudden contraction or expansion occurs in the connection duct 32, but the chambers are connected by the plurality of connection ducts 32. The pressure loss at the chamber connection is minimized.

  According to the embodiment described in detail above, the following excellent effects can be obtained.

  Since the flat air conditioning chamber 31 that is expanded horizontally in the same space is installed in the interstitial space K between the first floor part and the second floor part, the pressure loss at the time of blowing is reduced. Regardless of the outlet, a prescribed amount of blowing air can be secured. Moreover, in the air conditioning equipment of this embodiment, when installing the air conditioning chamber 31, it is not necessary to perform a special sealing operation or the like in the space between floors. As described above, it is possible to realize an air conditioning facility that has good workability in construction and that can obtain good air conditioning performance.

  Since the air-conditioning chamber 31 has a flat shape extended in the horizontal direction, the position of the opening 31a (opening leading to the air outlet) can be arbitrarily determined. Accordingly, it is possible to increase the degree of freedom of setting with respect to the indoor outlet position. It can be said that the ability to respond to the plan is enhanced. In renovation (repair, refurbishment), there is also an advantage that it becomes easy to change or add the outlet position.

  Since the air-conditioning chamber 31 is made of a highly heat-insulating and air-tight material, heat loss can be greatly reduced. In addition, condensation due to heat transfer of the structural material or the like can be prevented.

  Since the air conditioning chambers 31 are connected to each other by a plurality of connection ducts 32, even if the outer diameter of the connection duct 32 is limited by the hole diameter of the beam through hole 22a formed in the ceiling large beam 22, Pressure loss can be minimized.

  Since the air conditioning chamber 31 has substantially the same planar shape as the building unit 20, the volume of the air conditioning chamber 31 can be maximized according to the size of the building unit 20. Thereby, the pressure loss can be sufficiently reduced.

  The building unit 20 is produced in a factory with a predetermined size (standard). Therefore, in the configuration in which the air conditioning chamber 31 is installed in the building unit 20, the air conditioning chamber 31 may be prepared according to the unit size, and the production efficiency in manufacturing the air conditioning chamber 31 will be good.

  Since the air conditioning chamber 31 is installed using the interstory space between the first floor part and the second floor part, the air conditioning chamber 31 can be installed without providing a new space as an installation space for the air conditioning chamber 31. The chamber 31 can be suitably installed.

  In addition, a sound insulation effect can be expected in the air conditioning chamber 31. Therefore, the sound insulation performance between the upper and lower floors can be enhanced.

  Since the air conditioning chamber 31 is attached to the building unit 20 at the factory and then transported to the construction site, it is not necessary to install the air conditioning chamber 31 at the construction site (installation site). Thereby, construction work can be performed efficiently and field work can be shortened.

  Further, in the conventional configuration using existing air conditioning piping, if duct piping is performed without passing through the beam through hole 22a of the ceiling beam 22 in order to suppress pressure loss due to the air conditioning piping, a descending ceiling must be provided. Can also occur. In this regard, according to the configuration using the air conditioning chamber 31 as described above, it is unnecessary to provide a falling ceiling or the like. For this reason, the design deterioration due to the provision of the falling ceiling is suppressed, and a high-design living space can be realized.

  The present invention is not limited to the description of the above embodiment, and may be implemented as follows, for example.

  -As shown in FIG. 7, the structure which provides the control valve 41 which makes variable the passage area of the said connection piping part in the connection piping part including the connection duct 32 for connecting the some chamber 31 for an air conditioning is employ | adopted. . The control valve 41 is provided for each connection duct 32 between the chambers. Further, an air conditioning controller 42 made of a microcomputer or the like is provided, and the air conditioning controller 42 can control the opening / closing of the control valve 42. In addition, at this time, about the some control valve 41 provided between the same chambers, you may carry out open / close control of them individually, and you may carry out open / close control collectively.

  The air-conditioning controller 42 is sequentially input with various detection signals indicating the presence / absence of a user, preference for cooling / heating, health condition, and the like. At this time, an input device may be provided for each room, and the presence / absence of a user, preference for air conditioning / heating, health condition, and the like may be detected according to an input operation by a user. Or, when each user carries a portable communication device (including a key-type communication device and a card-type communication device) having a wireless communication function, user information, preference information regarding preference for cooling and heating, health information from the portable communication device It is preferable that the presence / absence of the user, the preference of cooling / heating, the health condition, and the like are detected based on the transmission information. The air-conditioning controller 42 determines the air-conditioning execution conditions based on the presence / absence of the user, the preference for cooling / heating, the health condition, and the like, and based on the execution conditions, the control valve 41 corresponding to the corresponding room is opened / closed and opened / closed. Perform degree adjustment.

  According to the configuration of FIG. 7, the passage area of the connection duct 32 (connection pipe portion) is changed by executing the opening / closing control of the control valve 41, and accordingly, through which air conditioning chamber 31 the conditioned air is circulated. Can be switched. As a result, the flow path of the conditioned air can be shortened as necessary, and appropriate air volume control is possible. In addition, since the opening / closing control of the control valve 41 is executed according to the presence / absence of the user, preference of cooling / heating, health condition, and the like, it is possible to perform optimum air volume control for each room.

  -In buildings, horizontal beams such as beams are not provided corresponding to all partitioning parts of rooms, etc., but for one partitioned space under the floor or behind the ceiling (compartment space by horizontal members) A plurality of partition spaces (rooms, etc.) may be provided. In such a building, the air conditioning chamber 31 may be divided in the same section in accordance with the partitioning position of the lower floor or the upper floor, and the divided chambers may be communicated with each other via the control valve 41. Accordingly, the used / unused chamber can be arbitrarily switched by operating the control valve 41, and air can be suitably blown to the space below or on the floor.

  The passage cross-sectional area of the connecting portion of the connection duct 32 with respect to the air conditioning chamber 31 may be gradually enlarged toward the air conditioning chamber 31 side. That is, as shown in FIG. 8, a conical cylindrical connecting portion 51 is provided at a connection portion of the connection duct 32 with the air conditioning chamber 31. In this connection part 51, the pipe diameter is configured to gradually and continuously expand toward the air conditioning chamber 31 side.

  In short, there is a concern that pressure loss may occur in the connecting portion between the air conditioning chamber 31 and the connection duct 32 due to a sudden change in the cross-sectional area of the passage. In this regard, according to the configuration of FIG. 8, it is possible to reduce pressure loss due to a sudden change in the passage cross-sectional area.

  In the above embodiment, the air-conditioning chamber 31 has a rectangular planar shape. However, this may be changed. In short, the air-conditioning chamber 31 is expanded horizontally in the space between the upper and lower building units. It may be anything that forms a flat shape. At this time, it is desirable that the air conditioning chamber has two sides that extend along two orthogonal beam members and have approximately the same length as the beam member, and has a polygonal planar shape.

  Specifically, the air-conditioning chamber 53 shown in FIG. 9A has a triangular shape having two end face portions 53a and 53b (two sides extending along a beam material not shown) orthogonal to each other. A plurality of connection ducts 54 are coupled to the end surface portions 53a and 53b, respectively. The air conditioning chamber 55 shown in FIG. 9B has a pentagonal shape having two end face portions 55a and 55b (two sides extending along a beam material not shown) orthogonal to each other. A plurality of connection ducts 56 are connected to the end surface portions 55a and 55b, respectively. Even if it is the structure of Fig.9 (a), (b), the pressure loss at the time of ventilation can still be reduced by setting it as a flat chamber as mentioned above.

  The air conditioning chamber 31 can be formed in a bag shape. Specifically, a vacuum heat insulating material, polystyrene foam, or polyurethane foam formed in a bag shape is employed.

  In the above embodiment, air is sent from the ceiling-side air conditioning chamber 31 to the space on the lower floor. However, air can also be sent from the floor-side air conditioning chamber 31 to the space on the upper floor. Good. That is, the air conditioning facility is a floor air conditioning facility. In this case, instead of the configuration in which the opening 31 a is formed in the lower surface portion of the air conditioning chamber 31, the opening 31 a is formed in the upper surface portion of the air conditioning chamber 31. And the blowing grill 33 is attached to the opening part 31a of the chamber upper surface part.

  ・ In addition to the floor space of the building, an air conditioning chamber is installed in the lower floor space of the lowest floor of the building (the lower floor space of the first floor), and the ceiling space on the top floor of the building (the ceiling and roof of the top floor) It is also possible to install an air conditioning chamber in between.

  -In the above-mentioned embodiment, although the example of application to a unit type building was explained, the present invention is applied to buildings of other structures such as a building constructed by a steel frame construction method and a building constructed by a conventional wooden construction method. Can be applied. In any case, in a building in which the space under the floor or the back of the ceiling is partitioned by a horizontal member such as a beam, a flat air conditioning chamber may be installed in the partitioned space.
