2. Description of the Related Art Conventionally, in a computer room such as a communication machine room, a plurality of IT equipment storage racks are arranged side by side to form a rack group, and this rack group is installed oppositely across a passage. There is what was installed. In such a general air conditioning system for a computer room, cold air blown out from an air conditioner is supplied into a double floor, and this cold air is supplied into a passage through a double floor opening panel between opposing rack groups. After that, it is supplied to the IT equipment to cool it.
However, a part of the cool air supplied into the passage through the double floor opening panel is mixed with the warm air exhausted from the IT equipment, which may cause a high temperature failure of the IT equipment and a decrease in efficiency of air conditioning.
Therefore, there is a configuration in which the warm air exhausted from the IT equipment and the cool air blown out from the air conditioner are not mixed by covering the ends of the passages between the rack groups, the ceiling, and the like with a shield. (For example, refer to Patent Document 1).

Japanese Patent No. 3833515

  By the way, when the rack group which opposes at the time of an earthquake etc. behave differently, in order to make the said shield follow this behavior, it is easy to become a complicated structure using many members. In addition, when maintaining equipment such as building lighting and fire alarms above the rack, it may be possible to remove the upper shield covering the upper side of the passage, but when the upper shield is made of panel material. However, there are problems such as poor work efficiency of removing panel materials one by one, danger of dropping the panel material during removal work, and securing a place for the removed panel material.

  The present invention has been made in view of the above circumstances, and in a computer room air conditioning system that uses a passage between racks arranged opposite to each other as an air guide passage, an upper shield covering the upper portion of the passage is simple and low-cost. It is an object of the present invention to facilitate the maintenance of the equipment above the rack and to make the upper shield correspond to different behaviors of the opposing rack group.

  As a means for solving the above-mentioned problem, the invention described in claim 1 is a device housing rack group which is installed on both sides of the passage to supply cooling air from the air supply surface and exhaust air heated from the exhaust surface. And cooling air blown out from the air conditioning device is blown to the floor through holes provided in the floor surface through the internal space under the floor, and the cooling air is supplied to the rack group. In a computer room air conditioning system that cools the equipment housed in the rack and then flows on the exhaust surface of the rack group as hot air and is sucked back into the air conditioner, the upper shield that covers the upper part of the passage And the upper shield is supported on both upper surfaces of the rack groups facing each other across the passage, and is movably supported on at least one of the upper surfaces. Frame-shaped frame If divided into a plurality of divided bodies together is removably attached to said frame, a portion of each of said plurality of divided bodies, characterized in that it comprises a seat which is fixedly held in the frame.

According to this configuration, the cost of the upper shield can be reduced by a simple structure in which the frame is placed across the upper surfaces of the opposing rack groups and the seat is attached to the frame. Moreover, it becomes easy to install the upper shielding body covering the upper part of the passage, and it is a simple construction without large-scale processing, so that the construction cost can be reduced. In addition, the cost can be reduced by diverting the existing frame material and sheet material. Further, by using a sheet for the upper shield, it is possible to avoid danger such as dropping of the panel material.
In addition, even if different behavior due to an earthquake or the like occurs in the opposing rack group, the frame is allowed to move differently because the frame of the upper shield is movably supported on at least one of the upper surfaces of the opposing rack group. However, it can be supported and the upper shield can be prevented from falling or breaking.
Further, by attaching and detaching the sheet divided in the length direction of the passage for each divided body, the upper shield can be easily opened and closed, and the maintenance work of the equipment above the rack can be easily performed. In addition, since a part of each divided body of the seat is fixed to the frame, it becomes possible to remove it from the frame while holding a part of each divided body in the frame. In addition to making it unnecessary to secure, it is possible to prevent an intake / exhaust failure caused by the sheet blocking the intake / exhaust port. Moreover, compared with the case where a panel material is used, the opening / closing operation | work of an upper shield can be simplified, working time can be shortened, and an air-conditioning state can be maintained favorable.

In the present invention, if the seat is configured to be detachably attached to the frame with a hook-and-loop fastener, the upper shield can be easily opened and closed, and maintenance of the equipment above the rack can be further facilitated. .
In the present invention, the sheet divided body is roughly divided into a first divided body that is attached to and detached from the frame from above and a second divided body that is attached to and detached from the frame from below, the first divided body and the first divided body. As long as the two divided bodies are arranged alternately, the plurality of divided bodies can be easily attached and detached as compared with the case where all the divided bodies are attached and detached from above or below the frame. In particular, when the seat is attached / detached from the passage, the seat can be attached in the order from the first divided body to the second divided body, and the sheet can be removed in the order from the second divided body to the first divided body. It is possible to easily attach and detach all the divided bodies and open and close the sheets from the inside.
In the present invention, if the structure is provided with a restricting member that is fixed to the upper surface of the rack group and restricts movement along the plane of the frame, the frame falls off the rack group due to excessive movement of the frame along the plane. This can be prevented.
In the present invention, if the second restriction member is provided between the upper surface of the rack group and the frame to restrict the movement of the frame, the frame falls over the restriction member and falls off the rack group. This can be prevented.
In the present invention, the frame includes a beam portion extending in the length direction, a beam portion extending perpendicularly to the length direction and detachably connected to the beam portion via a connector, and the beam portion. If the frame has a leg portion that extends downward from the intersection with the beam portion and is detachably connected to the beam portion and the beam portion via the connector, the existing frame member is used. The frame can be formed easily and at a low cost, and when the number of racks in the opposite rack group is different, it is easy to take measures such as replacing the legs with a length that reaches the floor surface. be able to. In addition, it is possible to cope with cases where the heights of the opposing rack groups are different, and it is easy to expand and contract when the number of racks increases or decreases.

  According to the present invention, in a computer room air conditioning system in which a path between groups of racks arranged opposite to each other is used as a wind guide path, the upper shield covering the upper side of the path has a simple and low-cost configuration, and the equipment above the rack Thus, the upper shield can be made to cope with different behaviors of the opposing rack groups.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 shows a computer room air conditioning system configured in a computer room of a building. The computer room is surrounded by the floor 1, a wall and a ceiling (not shown). A double floor 2 is provided above the floor 1 in a spaced manner. On the double floor 2, a plurality of IT equipment storage racks 3 are installed. The plurality of IT equipment storage racks 3 form a pair of rack groups 3L arranged in half in a row in the figure. The pair of rack groups 3L are opposed to each other with the passage 4 therebetween. Hereinafter, a direction along the rack group 3L is referred to as a length direction, and a direction orthogonal to the length direction is referred to as a width direction.

  In the internal space 5 below the double floor 2, electrical wiring (not shown) of each rack 3 and the like are accommodated. An air conditioner 6 is installed on the double floor 2 at a position spaced in the length direction from the end of the passage 4 in the extending direction of the passage 4. The air conditioner 6 sucks indoor air from the suction port 6a on the upper surface and cools it. The air cooled by the air conditioner 6 is sent to the internal space 5 of the double floor 2 from the air outlet 6b on the bottom surface of the air conditioner 6 as cooling air. The electrical wiring of the air conditioner 6 is also accommodated in the internal space 5 of the double floor 2.

  A portion of the double floor 2 facing the passage 4 is a perforated panel 7 having a large number of blowout holes. From the perforated panel 7, the cooling air sent to the internal space 5 of the double floor 2 is blown out into the passage 4. Each rack 3 has a front surface facing the passage 4 of the housing 3a as an air supply surface 3b. Each rack 3 takes in the cooling air blown into the passage 4 into the housing 3a from the air supply surface 3b, and cools the IT equipment accommodated in the housing 3a. The warm air after the device is cooled is exhausted upward (or in the back direction) from a fan 3c provided on the top surface (or the back surface) of the housing 3a.

Here, the basic operation of the computer room air conditioning system will be described.
During the operation of each rack 3, the fan 3 c operates and the air conditioner 6 is operated, and the cooling air blown out from the air conditioner 6 is supplied to the internal space 5 of the double floor 2. The cooling air supplied to the internal space 5 receives the blowing pressure of the air conditioner 6 and the suction pressure of the fan 3c, blows out from the perforated panel 7 on the floor surface into the passage 4, and the air supply surface of each rack 3 3b is sucked into the housing 3a. The cooling air sucked into the housing 3a is discharged upward or rearward of the housing 3a after cooling the heat generating device in the housing 3a. The released air (warm air) passes above each rack 3 and is sucked into the suction port 6a of the air conditioner 6, and again becomes cooling air and is blown out into the internal space 5.

  In each rack 3, an upper shield is provided between the upper surfaces 3d of the opposing rack groups 3L so that the warm air exhausted from the upper surface or the rear surface of the housing 3a is not directly sucked from the front surface of the housing 3a. It is desirable to close the top. Further, the end of the passage 4 in the length direction is provided with an end shield that extends between the ends of the opposing rack group 3L in order to suppress the discharge of the cool air supplied into the passage 4. It is desirable to close the ends.

Hereinafter, the upper shield 10 of the present embodiment will be described.
As shown in FIGS. 2 and 3, the upper shield 10 is attached to the frame 11 in a detachable manner, and a frame-like frame 11 that spans the upper surfaces 3 d of the rack group 3 </ b> L facing each other across the passage 4. And a sheet 21 covering the upper part of the passage 4.

  The frame 11 includes a tubular girder portion 12 extending along the length direction, and a tubular beam portion 13 extending along the width direction and detachably connected to the girder portion 12 via a connector 15. And a leg portion 14 having a tubular shape that extends downward from a crossing portion of the beam portion 12 with the beam portion 13 and is detachably connected to the beam portion 12 and the beam portion 13 via a connector 15. The frame 11 is supported on both upper surfaces 3d of the opposing rack group 3L by grounding the leg portions 14 to the upper surface 3d of the rack group 3L. A disc leg 14a for securing a ground contact area to the upper surface 3d of the rack group 3L is attached to the lower end portion of the leg portion 14. The disc leg 14a is preferably provided with a stopper (for example, an anti-slip sheet 14b described later) with respect to the upper surface 3d.

  Referring also to FIG. 5, the connector 15 is formed with insertion portions 15 a, 15 b, and 15 c of the beam portion 12, the beam portion 13, and the leg portion 14 that are orthogonal to each other. The number of the insertion parts 15a of the girder part 12 differs in the connecting tool 15 at the intermediate part in the longitudinal direction of the frame 11 and at the end part in the longitudinal direction (see FIG. 2). The girder part 12, the beam part 13, the leg part 14, the disc leg 14a, and the connector 15 are formed with rigidity by a metal or resin.

A pair of girders 12 have the same length as that of the rack group 3L in the length direction, and are provided as a pair spaced apart in the width direction. The pair of girders 12 are respectively arranged above the portions of the facing rack group 3L on the passage 4 side. The girder 12 may be divided in the length direction. In this case, as indicated by a chain line in FIG. 3, the frame 11 can be easily expanded and contracted as the number of racks increases or decreases.
The beam portion 13 has a length extending between the pair of beam portions 12 in the width direction, and a plurality of beams (five in this embodiment) are provided apart from each other in the length direction.
A plurality of leg portions 14 are provided for each position corresponding to the beam portion 13 in the length direction.

The frame 11 is supported on both upper surfaces 3d of the opposing rack group 3L in a state of being placed from above.
As shown in FIG. 5, the disk leg 14a of the frame 11 is grounded to the upper surface 3d of the rack group 3L via a non-slip sheet 14b such as a rubber plate. As a result, the position of the frame 11 in the horizontal direction (the direction along the surface along the two upper surfaces 3d) is stabilized in a normal time when the rack group 3L is not greatly shaken.

  Surface fasteners 24 and 25 for detachably attaching the sheet 21 are appropriately disposed on the upper and lower surfaces of the beam portion 12, the beam portion 13 and the leg portion 14 of the frame 11. The hook-and-loop fasteners 24 and 25 are defined in, for example, JIS L 3416, and are fixed to the frame 11 and the sheet 21 with a double-sided tape, an adhesive, or the like.

  Since the frame 11 is not fixed to the upper surfaces 3d and is supported only by placing, the frame 11 can move horizontally and move upward with respect to the rack group 3L even when a large behavior occurs in the rack group 3L due to an earthquake or the like. Is possible. That is, the frame 11 is supported so as to be movable with respect to the upper surfaces 3d of the opposing rack group 3L. For this reason, even when the rack groups 3L facing each other behave differently, the different behavior can be allowed without the frame 11 being deformed, broken or dropped.

  As shown in FIG. 2, a width direction stopper 16 for defining the amount of horizontal movement of the frame 11 in the width direction is fixed at a position adjacent to the leg portion 14 of the frame 11 on both upper surfaces 3d in the width direction. Established. For example, a plurality of width direction stoppers 16 are provided corresponding to the plurality of leg portions 14 of the frame 11. The width direction stopper 16 defines the amount of movement of the frame 11 in the width direction and prevents the frame 11 from falling into the passage 4.

Is fixed. The length direction stopper 17 is provided only at the end in the length direction of the frame 11, for example, but may be provided corresponding to the plurality of leg portions 14. The length direction stopper 17 defines the amount of movement of the frame 11 in the length direction, and prevents the frame 11 from falling off in the length direction.

  Between each width direction stopper 16 and the corresponding leg part 14, for example, a cable 18 made of a steel cord is bridged with a slack. The cable 18 prevents the frame 11 from dropping. In other words, the cable 18 can also be dropped even when the frame 11 is pushed up to the rack group 3L due to an earthquake or the like and is separated from the upper surface 3d of the rack group 3L and over the stoppers 16 and 17. To prevent.

  As shown in FIG. 3, the seat 21 includes a rectangular top plate portion 21 a extending between the pair of beam portions 12 of the frame 11, and a side plate portion 21 b extending by bending downward from both ends in the width direction of the top plate portion 21 a. And have. The sheet 21 is made of, for example, a sheet material having flexibility and strength and a certain degree of airtightness. The sheet 21 is divided into a plurality of divided bodies in the length direction. Hereinafter, the upper left divided body in the figure is referred to as a first divided body 22, and the lower right divided body in the figure is referred to as a second divided body 23.

  4 and 5 together, the first divided body 22 is detachably attached to the spar 12, the beam 13 and the leg 14 from the outside of the frame 11 with a surface fastener 24. On the other hand, the second divided body 23 is detachably attached to the beam portion 12, the beam portion 13, and the leg portion 14 from the inside of the frame 11 with a surface fastener 25. Reference numeral 26 in FIG. 5 denotes a binding band that prevents the end portions of the hook-and-loop fasteners 24 and 25 from being peeled off from the frame 11.

  An edge portion 22a of the first divided body 22 on the second divided body 23 side overlaps the beam portion 13 and the leg portion 14 located at the same position in the length direction from the outside of the frame 11, and the beam portion 13 and the leg portion 14 are overlapped. A surface fastener 24 is attached to the frame 11 from the outside. On the other hand, the edge 23a of the second divided body 23 on the first divided body 22 side overlaps the beam portion 13 and the leg portion 14 from the inside of the frame 11, and the beam portion 13 and the leg portion 14 from the inside of the frame 11. Mounted by hook and loop fasteners 25.

  Referring to FIG. 4, edge portions 22 a and 23 a on the other side of first divided body 22 and second divided body 23 are attached so as to be wound around beam portion 13. The surface fastener 24 for attaching the first divided body 22 to the beam portion 13 is provided along the outer peripheral surface of the beam portion 13 from the edge 13a outside the frame 11 of the beam portion 13 to the second divided body 23 side.

  Even if the surface fasteners 24 and 25 have regions extending in the shortening direction of the divided body attached to the end edges 13a and 13b from the inner and outer end edges 13a and 13b of the beam portion 13, the length of the sheet fastener 21 is reduced. When a pulling force in the direction acts, a force in the peeling direction acts on the region, and thus the effect of increasing the attachment strength of the divided body is thin. As shown in FIG. 4, the surface fasteners 24, 25 are provided on the sheet 21 when they are provided in regions extending from the inner and outer edges 13 a, 13 b of the beam portion 13 to the extending direction of the divided body attached to the edges 13 a, 13 b. When the pulling force in the length direction is applied, a force in the shearing direction that is relatively difficult to peel off acts on the region. Therefore, the area of the surface fasteners 24 and 25 is suppressed, and the attachment strength of the divided body is efficiently increased. be able to.

  As shown in FIG. 2 and FIG. 3, in the frame 11, when the space between the beam portion 13 and the leg portion 14 adjacent in the length direction is defined as one section, the first divided body 22 and the second divided body 23 are It is provided so as to cross over 11 two sections.
