  In the server room, as described in Patent Document 2, rack rows are arranged by a number of racks that accommodate servers. Cold air for cooling the servers housed in these racks is supplied to the server room, but the position of the cold air outlets and the direction of the cold air flow so that appropriate air conditioning can be performed according to the arrangement of the rack rows Is set.

  In order to perform efficient air conditioning, it is preferable that the cold air supplied to the server room is returned to the air conditioner from a predetermined position after being subjected to desired cooling. However, the supplied cold air may be returned to the air conditioner without being supplied into the rack. For example, as shown in FIG. 12, when the front surfaces of the rack rows 1a in which the racks 1 are arranged side by side face each other across the passage 2a, the cold wind Ac indicated by the white arrow is free access The floor is blown from the floor surface of the passage 2a to the server room and supplied into the rack 1. The cold air Ac supplied into the rack 1 is used for cooling the server accommodated in the rack, and is discharged from the rear surface of the rack 1. The back surfaces of the rack row 1a are installed facing each other across the passage 2b, and the discharged hot air Ah merges in the passage 2b. The air conditioner 3 is installed at a position facing each of the passages 2a and 2b, and is collected by sucking the hot air Ah, cooled, and then blown out again to the server room. Some of the cold air Ac blown and supplied from the floor surface flows along the passage 2a without being supplied to the rack 1 and is directly collected by the air conditioner 3. If the amount of cold air Ac that is recovered without being used for cooling becomes large, the air conditioning efficiency is lowered and wasteful air conditioning is performed. In consideration of this point, it is not realistic to change the installation position of the rack row and the air conditioner. Therefore, the cold air blowing direction is directed to the inside of the rack 1 or the like. The part is returned to the air conditioner 3 without being cooled.

  Further, there is a case where the hot air that has been heated to cool the servers in the rack 1 flows from the end of the rack row 1a and interferes with the flow path of the cold air. For this reason, when the temperature of the interfered cold air rises and this is used for cooling the server, the server may not be cooled to a predetermined state.

  Also, if it takes a long time to install a new server in a rack that does not contain a server, this empty rack will cause the flow of cold air to be different from the design of the air conditioning, which is irregular. The air conditioning efficiency of the server room may be reduced.

  Therefore, the present invention provides a structure for improving the efficiency of air conditioning in the server room, which can appropriately adjust the flow path of the conditioned air supplied to the server room and suppresses the decrease in the air conditioning efficiency of the server room. It is aimed.

  As a technical means for achieving the above object, the air conditioning efficiency structure in the server room according to the present invention is an air conditioning efficiency in the server room in which a plurality of racks capable of accommodating a plurality of servers are installed in a row. The air-conditioning structure is characterized in that the air path regulating sheet is disposed in front of the air inlet of the air conditioner and facing the cool air flow path.

  The cold air that is about to be returned to the air conditioner without being cooled is prevented from being sucked from the suction port by being obstructed by the air path regulating sheet. On the other hand, since the warm air supplied for cooling flows into the air path regulating sheet from an oblique direction, it is sucked from the suction port.

  According to a second aspect of the present invention, there is provided a server room air conditioning efficiency structure, wherein the server room air conditioning efficiency structure in which a plurality of racks capable of accommodating a plurality of servers are arranged in a row is arranged in a rack row. Cold air is fed into the sandwiched passage and supplied into the rack from the front of the rack, and the warm air heated for cooling is discharged from the back of the rack, and the end of the front of the rack row is It is characterized in that an air path regulating sheet extended outward from the rack row is provided.

  The hot air supplied to cool the servers in the rack is discharged from the back of the rack and returned to the air conditioner, and then flows along the end face of the rack row and flows into the front side of the rack row. And However, it is prevented from colliding with the air path regulating sheet and flowing to the front side of the rack row.

  According to a third aspect of the present invention, there is provided a server room air-conditioning efficiency structure, wherein the server room air-conditioning efficiency structure in which a plurality of racks capable of accommodating a plurality of servers are arranged in a line is provided. An air path regulating sheet is disposed at an appropriate position in the periphery, and an opening is formed in a part of the air path regulating sheet.

  Mixing of the flow of cold air and the flow of hot air is suppressed by the air path regulating sheet. At this time, if mixing is always prevented, the balance between the supply amount of the cold air supplied from the air conditioner and the return amount of the hot air may be lost. For this reason, an imbalance in the air volume is prevented through an opening formed in a part of the air path regulating sheet.

  In particular, when a considerable period of time is required to install a server in an empty rack, this air path regulation sheet is used, and the period until this installation becomes long. It is effective to correct.

  According to a fourth aspect of the present invention, there is provided a server room air conditioning efficiency structure, wherein the server room air conditioning efficiency structure in which a plurality of racks capable of accommodating a plurality of servers are arranged in a row is arranged in a rack row.

  Hereinafter, based on the preferred embodiment shown in the drawings, a structure for improving the efficiency of air conditioning in a server room according to the present invention will be specifically described.

  In the embodiment shown in FIG. 1, as shown in FIG. 2, the air path regulating sheet 5 is placed on the ceiling in front of the air inlet of the air conditioner 3 a facing the passage 2 a through which the cold air Ac flows. It is suspended from 4 and installed. Further, the airflow regulating sheet 5 is not installed in the air conditioner 3b facing the passage 2b sandwiched between the backs of the racks 1.

  In the structure for improving the efficiency of air conditioning in the server room according to this embodiment, the cool air Ac blown from the floor of the passage 2a flows along the passage 2a without being supplied into the rack 1, and enters the air conditioner 3a. The cold air Ac to be reached collides with the air flow regulating sheet 5 and is returned to the server room again without being returned to the air conditioner 3a. In addition, as shown in FIG. 1, the hot air Ah is returned to the air conditioner 3b installed facing the passage 2b, and from the space between the air conditioner 3a and the air path regulating sheet 5 to the air conditioner 3a. Returned. For this reason, it is preferable that the space | interval of the sheet | seat 5 for an air path regulation and the air conditioner 3a is set as an appropriate magnitude | size so that the warm air Ah is sucked.

  In the embodiment shown in FIG. 3, the air path regulating sheet 6 is suspended from the end of the rack row 1a in which the racks 1 are juxtaposed, and on the side of the passage 2 through which the cold air Ac is blown.

  The cold air Ac blown out from the passage 2 is guided by the air path regulating sheet 6 and flows to be used for air conditioning in the server room. On the other hand, when the hot air Ah discharged from the rear surface of the rack 1 tries to wrap around from the end surface of the rack row 1a to the front surface side of the rack 1, it collides with the air path regulating sheet 6 and thus the cold air Ac Desired air conditioning can be performed by the cold air Ac without interference.

  In the embodiment shown in FIG. 4, for example, when there is an empty rack 1 in preparation for the addition of servers, when it takes a long period of time to install equipment such as a server in the empty rack 1, Since it is useless to supply the cold air Ac to the empty rack 1, the air path regulating sheet 7 is disposed in an appropriate state around the rack row 1 a of the empty rack 1. At this time, since the airflow regulating sheet 7 does not exist in the original air conditioning design, the balance between the supply amount of the cold air and the return amount of the hot air is lost, and the desired air conditioning efficiency is ensured. This is inconvenient. In order to eliminate this inconvenience, an opening 7a is formed in the air path regulating sheet 7, and the inside and outside of the air path regulating sheet 7 are communicated.

  According to the embodiment shown in FIG. 4, the inside and outside of the air path regulating sheet 7 communicate with each other through the opening 7a, whereby the cold air Ac and the hot air Ah are exchanged, and the cold air Ac and the warm air are exchanged. This is intended to prevent an imbalance in the air volume with the wind Ah.

  By the way, as shown in FIG. 5, the air path regulating sheets 5, 6, 7 are arranged on the curtain ring 11 slidably connected to the curtain rail 10 as a support bracket on the ceiling 4. The hooks 12 locked to (6, 7) are linked and suspended. In this case, since a gap is formed by the portion of the curtain ring 11 and the hook 12, both sides of the air path regulating sheet 5 (6, 7) communicate with each other through the gap, and airtightness is impaired. Thus, the cold wind Ac may leak as indicated by the arrow P. Therefore, as shown in FIG. 6, the shielding sheet material 13 between the ceiling 4 and the curtain rail 10 is sandwiched, and the front end portion of the shielding sheet material 13 is attached to the air path regulating sheet 5 (6, 7). It is positioned below the upper end.

  The shielding sheet material 13 covers the curtain ring 11 and the hook 12, and shields the gap formed by them. For this reason, the cold air Ac is prevented from leaking by the shielding sheet material 13 as indicated by the arrow Q in FIG.

  FIG. 7 is a front view showing an example of the curtain rail 10. A curtain ring 11 is attached to the carriage 11 a on the curtain rail 10, and the carriage 11 a is slidable with respect to the curtain rail 10. Further, stoppers 11b are provided on both sides of the carriage 11a located at both ends of the curtain rail 10, and the carriage 11a located at both ends is fixed at the positions.

  FIG. 8 is a side view illustrating a support state of the lower end portion of the air path regulating sheet 5 (6, 7) when the air path regulating sheet 5 (6, 7) passes above the rack 1. FIG. The upper end portion of the air path regulating sheet 5 (6, 7) is slidably linked by the curtain rail 10 as described above. A hook-and-loop fastener 14a is attached to the lower end of the air path regulating sheet 5 (6, 7), and a hook-and-loop fastener 14b to be engaged with and disengaged from the hook-and-loop fastener 14a is attached to the upper surface of the rack 1. Yes.

  By engaging the hook-and-loop fasteners 14a and 14b, the lower end portion of the air path regulating sheet 5 (6, 7) is not opened, and the air tightness by the air path regulating sheet 5 (6, 7). Is maintained.

  FIG. 9 shows another structure when the air path regulating sheet 5 (6, 7) is suspended above the rack 1. In the case of the air path regulating sheet 5 (6, 7) suspended above the rack 1, it is slidably supported by the garten rail 10 and the air path regulating sheet 5 (6, 7) is slid. It is inconvenient if the movement is allowed. That is, since the air path regulating sheet 5 (6, 7) in the upper part of the rack 1 is shorter than the other parts, the air path regulating sheet 5 (6, 7) is slid. If the short part is displaced, the lower part of the short part is opened and the airtightness is impaired. For this reason, it is not necessary to make the air path regulating sheet 5 (6, 7) suspended above the rack 1 slidable. Therefore, as shown in FIG. 9, one side of the support bracket 20 made of equilateral angle steel is fixed to the ceiling 4 with a fixing bolt 21 or the like, and the flat bar 22 can be fixed to the other side with a fixing bolt 23 or the like. Then, the air path regulating sheet 5 (6, 7) is sandwiched between the other side of the support bracket 20 and the flat bar 22, and the fixing bolt 23 is tightened to wind the air path regulating sheet 5 (6, 7). Is fixed.

  Further, the lower end portion of the air path regulating sheet 5 (6, 7) is prevented from being detached from the upper surface of the rack 1 by the hook-and-loop fasteners 14a and 14b, as in the embodiment shown in FIG. is there.

  According to the embodiment shown in FIG. 9, the air path regulating sheet 5 (6, 7) suspended above the rack 1 does not move carelessly. Therefore, the air path regulating sheet 5 ( The airtightness according to 6, 7) is reliably maintained.

  Further, a weight 25 made of a stainless steel chain or the like is attached to the lower end portion of the air path regulating sheet 5 (6, 7) suspended at a portion other than the upper portion of the rack 1 as shown in FIG. The air path regulating sheet 5 (6, 7) is suspended in tension due to its weight.

  In the embodiment described above, the air path regulating sheet 5 (6, 7) has been described as a sheet-like one. However, as shown in FIG. 11, a plurality of belt-like sheet materials 30 are suspended. It doesn't matter. It is a so-called warm shape, and it is preferable that the end of the strip-shaped sheet material 30 is suspended by being overlapped with the end of the adjacent strip-shaped sheet material 30. According to the warm air-conditioning sheet 5 (6, 7), an operator or an administrator can easily pass the air-path restricting sheet 5 (6, 7) by scraping the belt-like sheet material. it can. In addition, these sheet materials 30 are suspended in a state of being always tensioned by appropriately setting the width of the overlapping portion or appropriately adjusting the weight of the sheet material 30 so as not to be inadvertently opened.
