JP 2007-232312 A

  By the way, in recent years, as a large number of information processing devices accommodated in the device accommodating portion, devices with high heat generation are increasing due to operation, and the amount of cold air (adjusted air amount) for cooling them tends to increase. Therefore, even if an efficient water circulation method using water as a heat medium is adopted, it is necessary to circulate a large amount of water between the heat source device and each air conditioner through the air conditioning pipe.

  However, when circulating a large amount of water in this way, if the air conditioning piping breaks, such as cracks or breaks in the joints, a large amount of water leaks into the building from the air conditioning piping installed inside the building. There is a risk that information processing equipment (or information contained in the equipment) will break down when it gets wet with a large amount of water. In particular, such a situation becomes a serious problem that reduces the reliability of the data center.

  The present invention has been made in view of the above-described situation, and its main problem is to suppress the failure of the information processing device accommodated in the device accommodating portion even when the air conditioning piping is damaged. It is in the point of providing a reliable data center that can.

The first characteristic configuration of the present invention is a data center provided with a plurality of air conditioners for air-conditioning the equipment housing section, and having a equipment housing section for housing a large number of information processing equipment inside.
A central heat source machine that circulates a heat medium between the plurality of air conditioners through an air conditioning pipe and an outdoor balcony are provided,
The air-conditioning piping is arranged in a state where the outdoor balcony is used as a main piping route.

  That is, according to this configuration, first, cold heat or heat can be efficiently generated by the central heat source device that circulates the heat medium between the plurality of air conditioners, and the air conditioning of the device housing portion can be efficiently performed. It becomes possible to do.

  Nevertheless, since the air conditioning piping is arranged with an outdoor balcony as the main piping route, even if the air conditioning piping is broken, such as cracks, the main leakage point of the heat medium can be determined. It can be set as an outdoor balcony separated from the device housing portion, and accordingly, it is possible to prevent the information processing device housed in the device housing portion from being damaged due to breakage of the air conditioning piping.

  Moreover, at the time of maintenance of the air conditioning piping, for example, at the time of large-scale repairs where the piping material of the air conditioning piping is replaced by a large number of workers, the replacement work can be performed on an outdoor balcony that is separated from the equipment accommodating portion. It is possible to prevent a large number of workers from entering a device housing unit that requires high confidentiality.

  Furthermore, if a door for entering the air conditioner installation section is provided on the outside wall of the outdoor balcony, maintenance such as inspection, repair, and renewal of the air conditioner can be performed from the outdoor balcony. It is possible to prevent an operator from entering a device housing unit that requires high confidentiality not only in piping but also in maintenance of an air conditioner.

  That is, according to this first characteristic configuration, it is possible to suppress the occurrence of a failure of the information processing device due to the breakage of the air conditioning piping, and it is possible to maintain high confidentiality of the device accommodating portion even at the time of maintenance, From these things, the reliability as a data center can be improved significantly.

  The second characteristic configuration of the present invention is that the circulation pipe is suspended from the bottom of the outdoor balcony.

  In other words, according to the above configuration, the floor (upper surface) of the outdoor balcony can be released by suspending the air conditioning pipe on the bottom (lower surface) of the outdoor balcony, so that the floor is evacuated. It can be used for various applications such as passages and maintenance spaces. Therefore, the outdoor balcony can be effectively used as compared with the case where the air conditioning pipe is laid on the floor (upper surface) of the outdoor balcony.

  Furthermore, according to this structure, an outdoor balcony becomes a fence with respect to an air conditioning piping, it can prevent that an air conditioning piping is exposed to sunlight or rain, and can prevent deterioration of the air conditioning piping by environmental load.

  Also, if the floor of the outdoor balcony is made of precast concrete board, it will be possible to hang the precast concrete board and air conditioning pipe together by installing air conditioning pipes on the bottom of the precast concrete board on the ground during construction. , Can streamline the construction.

  In addition, the upper floor and the lower floor outdoor balconies are the same in plan view so that the maintenance of the air conditioning piping suspended from the bottom of the upper floor outdoor balcony can be performed using the floor of the lower floor outdoor balcony as the work floor. It is desirable to provide it at a position.

The third characteristic configuration of the present invention is a double floor structure in which the floor structure of the device accommodating portion is disposed above the slab with a space therebetween.
The height position of the floor surface of the outdoor balcony is equivalent to the height position that is closer to the floor surface between the upper surface of the slab of the device housing portion and the floor surface of the device housing portion, or the floor surface of the device housing portion. Or it is in the point set to the substantially equivalent height position.

  In other words, according to this configuration, since the floor structure of the device accommodating portion is a double floor structure in which a floor is disposed above the slab with a space therebetween, the space between the slab and the floor is used for air conditioning. It can be used effectively, for example, by using it as a wind path.

  And according to this configuration, the height position of the floor surface of the outdoor balcony is the height position that is closer to the floor surface of the device housing portion among the upper surface of the slab of the device housing portion and the floor surface of the device housing portion, or Therefore, the height of the floor of the equipment storage section is adopted while adopting the above-described efficient double floor structure for the equipment storage section. For example, to make it easier to move between the equipment housing part and the outdoor balcony, or to install an air conditioner near the wall on the equipment housing part side. Maintenance of the air conditioner from the balcony side can be facilitated.

  The 4th characteristic structure of this invention exists in the point which has arrange | positioned the shielding board on the outer side of the said outdoor balcony.

  That is, according to this configuration, the shielding plate disposed outside the outdoor balcony can prevent intrusion of people from the outside to the outdoor balcony, and can enhance the security function of the data center.

  In addition, according to this configuration, the air-conditioning pipe can be prevented from being exposed to the eyes of an outside person by the hiding action (blind-folding action) of the air-conditioning pipe by the shielding plate, and the design of the exterior of the building is improved. be able to.

  Further, the shielding action of the air conditioning piping by the shielding plate can prevent the air conditioning piping from being exposed to sunlight or rain, and can also prevent deterioration of the air conditioning piping due to the environmental load.

  Moreover, even when an outside air inlet such as a louver is provided on the outer wall on the outdoor balcony side and the outside air conditioning is performed on the equipment accommodating portion, it is possible to prevent rainwater from entering the outside air inlet by this shielding plate, Accordingly, a dedicated rainwater intrusion prevention measure for the outside air intake can be made unnecessary or simple to increase the amount of outside air taken in, and the outside air conditioning can be performed efficiently.

According to a fifth characteristic configuration of the present invention, the shielding plate includes a wave-shaped perforated plate having an upward surface facing obliquely upward and a downward surface facing obliquely downward, and a plurality of holes dispersedly formed. As well as
The aperture ratio of the upward surface is set larger than the aperture ratio of the downward surface.

  In other words, according to this configuration, the shielding plate is composed of a corrugated perforated plate having an upward surface facing obliquely upward and a downward surface facing obliquely downward, and in which a large number of holes are dispersedly formed. Therefore, it is possible to obtain a sufficient strength by the corrugated structure while ensuring an opening area (ventilation area) by a large number of dispersed holes.

  In addition, since the aperture ratio of the upward surface is set to be larger than the aperture ratio of the downward surface, sunlight from the upper side is efficiently taken in by the upward surface having a large aperture ratio, and the downward direction has a small aperture ratio. The surface can effectively block a person's line of sight from the lower side.

  Therefore, it is possible to efficiently and effectively shield the outdoor balcony where the air-conditioning pipes are installed, while ensuring the aperture ratio necessary for the outdoor balcony according to the Building Standard Law as a whole.

  In addition, in the implementation of the fifth characteristic configuration, if the configuration of the second embodiment in which the air conditioning pipe is suspended from the bottom of the outdoor balcony is also implemented, sunlight does not reach the air conditioning pipe with the outdoor balcony as a fence. In other words (in a state in which deterioration due to the environmental load of the air conditioning pipe is suppressed), sunlight can be efficiently taken in from the upper side by the upward surface having a large aperture ratio.

  1 and 2 are equipped with a device accommodation room 2 (an example of a device accommodation unit) that accommodates a large number of information processing devices 1 such as computers, servers, routers, etc. on a plurality of floors, and a central type air conditioning system is adopted. Data center C is shown.

  The air conditioning system includes an air handling unit 3 (an example of an air conditioner) incorporating a blower, a heat exchange coil, and the like (not shown), a water-cooled central heat source unit 4 as a cooling source, and the air handling unit 3 and the center. An air conditioning pipe P that circulates cold water (an example of a heat medium) with the heat source unit 4 is provided as a main component.

  A plurality of air handling units 3 are arranged in parallel with respect to each of the device storage chambers 2. The central heat source unit 4 may be arranged at an appropriate place according to the building structure such as the basement, the ground floor, and the rooftop and the surrounding environment. Reference numeral 5 denotes a cooling tower that cools the cooling water used in the central heat source unit 4 and is appropriately provided depending on the type of the central heat source unit 4.

  The equipment storage chamber 2 accommodates the information processing equipment 1 at a high density by arranging a large number of racks 6 in which the information processing equipment 1 is installed in a multi-tiered state. In addition, an air conditioning machine room 7 in which the air handling unit 3 is installed is provided in the vicinity of the equipment housing room 2.

  In this example, the floor structure of the equipment storage chamber 2 is a double floor structure in which a floor material 2a is provided above the floor slab 2A, and the internal space 2b of the double floor structure is used as an adjacent air conditioning machine. Communicatingly connected to the air inlet 7a formed in the floor portion 7A of the chamber 7 (an example of the lower part of the air conditioning machine room 7), and further connecting the air outlet to a plurality of locations (locations near the rack 6) of the floor material 2a of the equipment storage chamber 2 2c is provided. The air supply duct 3 </ b> A of the air handling unit 3 is connected to the air inlet 7 a of the air conditioning machine room 7.

  That is, the floor internal space 2b of the equipment storage chamber 2 is used as a supply path of the adjusted air SA from the air conditioning machine room 7 to the equipment storage room 2, and the adjustment air SA by the air handling unit 3 of the air conditioning machine room 7 is blown into the intake duct 3A. It is configured to blow upward from the floor of the equipment storage chamber 2 through the mouth 7a, the floor internal space 2b, and the air outlet 2c.

  In addition, the ceiling structure of the equipment storage room 2 is structured to have a ceiling material 2d with a space below the floor slab 2A, and the ceiling back space 2e of the equipment storage room 2 is divided into a partition of the adjacent air conditioning machine room 7. In communication with a return air port 7b formed in the upper part of the wall 7B (an example of the upper part of the air conditioning machine room 7), openings 2f are provided at a plurality of locations of the ceiling material 2d of the device housing chamber 2. A return air duct 3B of the air handling unit 3 is connected to the air inlet 7a of the air conditioning machine room 7.

  That is, the ceiling back space 2e of the device storage chamber 2 is used as a return air path for the indoor air RA from the device storage chamber 2 to the air conditioning machine room 7, and the opening 2f of the device storage chamber 2, the ceiling back space 2e, and the return air port 7b. The indoor air RA is returned to the air handling unit 3 through the return air duct 3B.

  The partition wall 7B between the equipment storage chamber 2 and the air conditioning machine room 7 has a door 7C for entering the air conditioning machine room 7 from the equipment storage room 2 (inside the building) during maintenance of the air handling unit 3 or the like. Is provided.

  In this data center C, an outdoor balcony 8 is provided, and the air-conditioning pipe P is arranged with the outdoor balcony 8 as a main piping path, and water leaks from the air-conditioning pipe P due to breakage of the air-conditioning pipe P or the like. However, the information processing device 1 housed in the device housing chamber 2 is prevented from getting wet.

  The outdoor balcony 8 is installed at least one floor above the installation floor of each air conditioning machine room 7, and in this example, the outdoor balcony 8 on each floor is installed at the same position in plan view. The air-conditioning pipe P is suspended from the bottom of the outdoor balcony 8 in a state of being along the balcony length direction by a lifting tool such as a suspension base 9 attached to the bottom of the outdoor balcony 8.

  Therefore, the outdoor balcony 8 can be used as a maintenance deck for the air-conditioning pipe P, and maintenance of the air-conditioning pipe P can be easily performed while avoiding an operator from entering the highly sensitive equipment storage room. Further, the outdoor balcony 8 can be used as a trap to prevent deterioration of the air conditioning pipe P due to the environmental load (load due to sunlight or wind and rain). Further, by forming the floor portion of the outdoor balcony 8 with a precast concrete plate, the precast concrete plate and the air conditioning piping P are lifted together in a state in which the air conditioning pipe P is attached to the bottom of the precast concrete plate on the ground. It is possible to streamline the construction.

  As shown in FIG. 2, the air-conditioning pipe P includes a system constituted by the outgoing pipe p1 and the return pipe p2, and a plurality of systems constituted by the outgoing pipe p3 and the return pipe p4. The balcony 8 is provided with security devices (not shown) such as monitoring sensors and cameras.

  The air handling unit 3 of the air conditioning machine room 7 on each floor has a pair of going back and forth from the place where the air handling unit 3 is installed in the air conditioning pipe P suspended from the bottom of the balcony one floor above the installation floor or from the vicinity thereof. The branch pipes p5 and p6 are branched and connected to the air handling unit 3 through a through hole 12a formed in the upper part of the outer wall 12 on the installation floor.

  The height position h1 of the floor surface of the outdoor balcony 8 is the height position h2 of the upper surface of the floor slab 2A on the building main body side provided with the device storage chamber 2, and the height position h3 of the floor surface of the device storage chamber 2. Among these, the height position close to the floor of the equipment storage chamber 2 (that is, the height position closer to h3 than h2) is set.

  In this example, in order to construct a double floor structure on the building body side, the girder 10 is a reverse beam (that is, the floor slab 2A is connected to the lower end line of the inner surface 10a of the girder 10), and the flooring 2a is used as the girder. The floor slab 8A of the outdoor balcony 8 is connected to the upper end of the outer surface 10b of the girder 10 so that the height position h1 of the floor surface of the outdoor balcony 8 is set. The height position is set as described above.

  Further, in this data center C, a shielding plate 11 that covers the entire outside of the outdoor balcony 8 (specifically, the outer edge of the outdoor balcony 8) is provided, and the shielding plate 11 conceals the air conditioning pipe P. The action (blindfolding action) prevents the air conditioning pipe P from being exposed to the eyes of an external person, and prevents deterioration of the air conditioning pipe due to the environmental load.

  This shielding plate 11 is fixed to a vertical base material 13 made of steel attached at a predetermined pitch in the balcony length direction by fixing means (not shown) such as screws.

  As shown in FIG. 3, the shielding plate 11 has an upward surface 11A that faces obliquely upward, a downward surface 11C that faces obliquely downward, and a vertical surface 11B that connects these tips, and has a large number of holes. 11a is made of a perforated steel plate (an example of a perforated plate) such as a corrugated punching metal formed in a dispersed manner.

  The opening ratio of the upward surface 11A is set larger than the opening ratio of the downward surface 11C and the opening ratio of the vertical surface 11B. The aperture ratio of each surface 11A to 11C is adjusted by changing the size (opening dimension) of the hole 11a on each surface. In addition, the hole 11a of the vertical surface 11B is configured to be smaller than the downward surface 11C corresponding to the vertical width dimension on the short side.

  Therefore, in the state where sunlight L does not reach the air conditioning pipe P with the outdoor balcony 8 as a fence (that is, in a state where deterioration due to the environmental load of the air conditioning pipe P is suppressed), the upward surface 11A having a large aperture ratio causes the sun from the upper side. The light L (see FIG. 3B) is taken in efficiently, and the human's line of sight E (see FIG. 3B) from the lower side is effective by the downward surface 11C (and the vertical surface 11B) having a small aperture ratio. Therefore, it is possible to efficiently shield the outdoor balcony 8 provided with the air-conditioning pipe P while securing the opening ratio necessary for the outdoor balcony 8 in the Building Standard Law as the entire shielding plate 11. Can be done effectively.

By providing it on the outer wall 7B, the operator may enter the air conditioning machine room 7 from the outdoor balcony 8 and perform maintenance of the air handling unit 3 without entering the highly confidential device housing room 2.

  (2) In the above-described embodiment, the case where the air-conditioning pipe P is suspended from the bottom of the outdoor balcony 8 is shown as an example, but it may be laid on the floor of the outdoor balcony 8 or embedded in the outdoor balcony 8. You may arrange | position in a state.

  (3) The heat medium circulated between the central heat source unit 4 and the air handling unit 3 is not limited to the cold water shown in the above-described embodiment, but is brine, ice water slurry, hot water, steam, a circulating refrigerant of the refrigeration circuit, or the like. There may be.

  (4) In the above-described embodiment, the case where the height position h1 of the floor surface of the outdoor balcony 8 is set to a height position that is closer to the floor surface between the upper surface and the floor surface of the slab 2A of the equipment storage chamber 2 is used. Although shown in the example, it may be set to a height position equivalent to or substantially equivalent to the height position h3 of the floor surface of the device accommodating portion.

  (5) In the above-described embodiment, the case where the entire outer surface of the outdoor balcony 8 is covered with the shielding plate 11 is shown as an example. However, the height range corresponding to the waist wall on the outer side of the outdoor balcony 8 (an example of a partial region) ) May be covered.

  (6) The shielding plate 11 is not limited to the wave shape but may be a flat plate shape or the like, and may be configured not only from the perforated plate but also from a non-porous plate.

(7) As an improvement of the above-described embodiment, an external air inlet such as a louver may be provided on the outer wall 7B on the outdoor balcony 8 side to perform external air conditioning on the device storage chamber 2. In this case, since the intrusion of rainwater into the outside air intake can be prevented by the shielding plate 11, the amount of intake outside air is increased by making unnecessary dedicated rainwater intrusion prevention measures for the outside air intake correspondingly. Therefore, the outside air conditioning can be carried out efficiently.
