  In the above-described conventional technology, the underfloor space of the free access floor can be partitioned by a partition plate, but the structure for attaching the partition plate is complicated, and for example, the rack containing IT equipment such as a data center is frequently increased or decreased. If the position of the rack is changed or the position is changed, the installation position of the partition plate can be changed easily and quickly in response to the increase or decrease of the rack or the position change, and the flow direction of air such as cooling air flowing under the floor Could not be changed easily. For this reason, heat problems that make the system unstable, such as heat accumulation (a phenomenon in which high temperature parts appear in areas that should be low temperature such as the intake surface of IT equipment), are likely to occur, and there are no racks in the initial operation of the data center. (Cooling not required) If the cold air diffuses into the underfloor area, excess air conditioning power will be used. In order to reduce power consumption, the development of technology that makes it possible to easily change the flow of cooling air in the underfloor space is aimed at reducing power consumption and increasing carbon dioxide emissions in the larger data centers associated with IT. At present, trying to reduce the amount, it is a prominent problem.

  The technique disclosed in this application has been made to solve the above-described problems, and an object thereof is to provide a technique that can easily change the air flow in the underfloor space.

  In order to solve the above-described problem, the free access floor is a free access floor formed by arranging a plurality of free access panels on a foundation floor via a space, and any of the plurality of free access panels is provided. Each of the one or any of the plurality of free access panels is provided with a slit, and a partition plate for defining a flow direction of the air flowing through the space is suspended from the surface of the free access panel. It is provided so that it can be inserted and removed.

  There is an effect that the flow of air in the underfloor space can be easily changed.

  Hereinafter, embodiments will be described with reference to the drawings. It should be noted that the free access floor in the embodiment can be applied to a floor of a data center where a server or the like constitutes and stores racks that are frequently increased or decreased or rearranged.

  FIG. 1 is a plan view showing a part of a free access floor, and FIG. 2 is a cross-sectional view taken along the line II-II in FIG. 1 and 2, the free access floor 1 is arranged so that a plurality of free access panels 1a are arranged in a plane to form a floor. The free access floor 1 is supported by a plurality of columns 3 erected on the foundation floor 2, and a space is formed between the free access floor 1 and the foundation floor 2.

  In this example, each free access panel 1a has a rectangular shape, and each column 3 supports a position where the tops of the four free access panels 1a are in contact. Thereby, each support | pillar 3 is supported in the position which makes the top part of each free access panel 1a the approximate center of the support surface of each support | pillar 3. As shown in FIG.

  A slit 5 is provided in some of the free access panels 1a. The slit 5 is provided in any one of the plurality of free access panels 1a or each of the plurality of free access panels 1a.

  Of these slits 5, the predetermined slit 5 has a partition plate 6 that determines the flow direction of the air flowing through the space formed between the foundation floor 2 and the free access floor 1, as shown in FIG. 3. Inserted. The partition plate 6 is provided so as to hang from the surface of the free access panel 1a and be detachable.

  In the above configuration, the slit 5 described above is provided between the support columns 3 that support each free access panel 1a on the foundation floor 2 in the free access panel 1a in which the slit 5 is provided, and when the partition plate 6 is inserted, The support 3 and the partition plate 6 can spatially partition one side of the free access panel 1a.

  In addition, about the slit 5 into which the partition plate 6 is not inserted, as shown in FIG. 4, the closing plate 7 is fitted to close the slit 5. That is, each slit 5 is provided with a stepped portion 5a on the upper surface side of the free access panel 1a, and a closing plate 7 is fitted into the stepped portion 5a to face the free access panel 1a, that is, the surface of the free access floor 1. Is kept flush with the slit 5. Moreover, when using the partition plate 6, the partition plate 6 is supported by latching the support part 6a provided in the upper edge of the partition plate 6 to the step part 5a.

  The partition plate 6 shown in FIG. 4 is a plate-like member such as wood or plastic, and is integrally formed with the support portion 6a.

  In FIG. 1, the case where one slit 5 is provided in one free access panel 1a has been described. However, as shown in FIGS. 5A, 5B, and 5C, one free access panel is provided. A plurality of slits 5 may be provided in 1a, and a partition plate 6 may be inserted into each. In the case of FIG. 5, the plurality of slits 5 are provided so as to be orthogonal to each other or parallel to each side of the rectangular free access panel 1a.

  Here, another configuration of the partition plate will be described. Although the partition plate 6 shown in FIG. 3 is composed of a plate-like member, the partition plate 16 can be composed of a flexible member as shown in FIG. In the partition plate 16 shown in FIG. 6, a partition portion 16b made of a flexible fabric having a size and shape sufficient to block the space under the panel is attached to the support portion 16a, and a plurality of weights 16c are attached to the lower edge thereof. It is constituted by. As this fabric, for example, a synthetic fabric such as nylon or polyester, a vinyl chloride sheet, or the like can be used. Further, a metal material such as iron or a plastic resin material can be used for the weight 16c.

  By making the partition plate 16 flexible in this way, for example, as shown in FIG. 7A, when there is an obstacle 9 on the foundation floor 2, the upper end of the partition plate 16 from the free access floor 1. The hanging amount of the partition plate 16 (the length in the height direction of the partition portion 16b) can be adjusted without projecting the portion (support portion 16a), and the underfloor space can be easily partitioned. Moreover, as shown in FIG.7 (b), it is the same also when the foundation floor 2 becomes high.

  When the partition plate is formed of a flexible member, the partition plate is attached to the support portion as shown in FIG. 8 with the adhesive or adhesive on the upper edge of the flexible member 16d constituting the partition portion 16b. As shown in FIG. 9, the upper edge of the flexible member 16d can be mechanically fixed with a hook, a pin, a screw 11, or the like.

  FIG. 10 shows an example of the free access floor 1 according to the embodiment. A cooling air flow path R is formed under the floor by combining a plurality of free access panels 1a provided with partition plates 6 (or 16). That is, the cooling air blown from the air conditioner 20 is efficiently flowed only through the flow path formed by being partitioned by the partition plate, and does not flow to other places where cooling is not required. The flow path can be easily changed by using or not using a partition plate or appropriately selecting the slit direction of the free access panel with respect to the slit of the free access panel.

  Thereby, according to the embodiment, for example, cold air to an area that does not require cooling can be easily shut off at the initial operation of the data center, so that the power cost of the air conditioner can be reduced. In addition, the analysis accuracy can be improved because it can be easily matched with the analysis area cut out when modeling the air conditioning simulation. Furthermore, it is possible to easily work from above the free access floor and to change the flow direction of the wind with a rack device, an air conditioner, and the like installed.
