Description

  The present invention relates to a computer room air conditioning system.

Conventionally, various air conditioning systems for adjusting the air flow and temperature in a certain space have been proposed.
In this type of air conditioning system, there is a computer room that adjusts the air flow and temperature around the equipment in the computer room where IT equipment and communication devices that tend to be highly integrated and heat-generating are installed. Air conditioning systems are known.
As an air conditioning system for a computer room, for example, a plurality of equipment storage racks arranged opposite to each other across a passage, and a side of the equipment storage rack, which is disposed outside the passage in the extending direction. Some are equipped with an air conditioner.

  Under such a configuration, when the air conditioner sends the cooling air toward the passage, the cooling air is sucked into the equipment housing rack. The cooling air is warmed by cooling the equipment housed in the equipment housing rack, and then blown out from the upper surface or the back surface of the equipment housing rack. The air thus warmed and blown out flows in the upper space of the computer room, is sucked into the air conditioner and cooled again, and then sent out toward the passage. Thereby, the flow and temperature of the air in the computer room are controlled.

However, some of the air that has been warmed and blown out from the equipment housing rack may be directly returned to the passage from the upper space without being sent to the air conditioner. In this case, the air recirculated to the passage is sucked into the equipment housing rack again in a warmed state, thereby reducing the cooling efficiency of the equipment.
Therefore, for example, in the air conditioning system for a computer room described in Patent Document 1, a space in the passage and the space above the passage are provided by bridging a shielding plate between the upper surfaces of the equipment storage racks facing each other across the passage. To regulate the flow of air.

Japanese Patent No. 3833515

  However, in such a computer room air conditioning system, the arrangement of equipment storage racks is diversified according to various on-site layouts. As described above, the equipment storage racks are opposed to each other across the passage. It is not always done. In this case, as in Patent Document 1 described above, it is not possible to bridge the shielding plate between the device accommodation racks.

  Here, the case where a shielding board cannot be bridge | crossed between apparatus accommodation racks is demonstrated concretely using figures. 26 to 28 are plan views for explaining the layout in the computer room, and reference numeral 3 in the figure indicates a passage provided in the computer room. In FIGS. 26 to 28, the passage 3 extends in the vertical direction of the figure, and the floor of the passage 3 is provided with a floor opening 5 for sending the cooling air toward the passage 3. It has been. Reference numeral 7 in the drawing denotes a plurality of equipment storage racks arranged along the passage 3. In the example of FIG. 26, the equipment accommodating rack 7 is disposed along the passage 3 only on one side (the right side in FIG. 26) of the passage 3 in the width direction (the left-right direction in FIG. 26). In the example of FIG. 27, the wall surface 1A of the computer room is located on the opposite side (left side in FIG. 27) across the passage 3 of the equipment housing rack 7. In such a case, even if it tries to bridge the said shielding board from the upper surface of the apparatus accommodation rack 7 toward the channel | path 3, it will be in a cantilever state, Therefore This shielding board cannot be arrange | positioned.

  In addition, as shown in FIG. 28, even when the equipment-accommodating racks 7 are arranged to face each other across the passage 3 in the width direction, the equipment-accommodating rack 7 on one side in the width direction is The length along the passage 3 may be set longer than the device housing rack 7 on the other side in the direction. Also in this case, the shielding plate cannot be provided in a portion (region X shown in FIG. 28) of the one-side device housing rack 7 that is not disposed opposite to the other-side device housing rack 7. In addition, in the installation examples of FIGS. 26 to 28, a plurality of equipment storage racks 7 are arranged along the passage 3 to form a so-called “line”. In some cases, the column is not configured. That is, there are cases where the equipment-accommodating rack 7 is installed alone or randomly, and in such a case, the shield cannot be provided.

  The present invention has been made in view of such circumstances. For example, even in an on-site layout in which a device storage rack is disposed only on one side in the width direction of the passage, An object of the present invention is to provide an air conditioning system for a computer room that can reliably partition the external space and can efficiently cool the equipment accommodated by the equipment accommodation rack.

In order to achieve the above object, the present invention proposes the following means.
That is, the present invention is installed along a passage having an internal space under the floor, supplies air from the front surface facing the passage, and blows out heated air from the upper surface or the back surface, and the sucked air. Cooling air sent from the air conditioner flows through the internal space and flows from the floor opening provided in the floor of the passage onto the floor of the passage. An air conditioning system for a computer room in which cooling air cools a device housed in the device housing rack, and then flows through a space above the device housing rack and is sucked into the air conditioner again. A shielding body having a ceiling wall portion extending from the upper surface of the equipment housing rack toward the passage side, and a sidewall portion extending from the ceiling wall portion toward the floor is provided. Equipment storage Front side passage space defined from the external space on the rack defined forms intersection angles between the side wall and the top wall portion is an angle adjustable by rotating the side wall portion In addition, the size of the space in the passage is adjustable, the crossing angle is set corresponding to a dimension along the width direction of the passage of the floor opening, and the lower end portion of the side wall portion is It arrange | positions rather than the floor opening part on the outer side of the said width direction .

  According to the computer room air conditioning system of the present invention, the top wall portion of the shield partitions the space in the passage and the upper space of the equipment housing rack, and the side wall portion is for accommodating the space in the passage and the equipment in the passage. A side space located on the side opposite to the front side of the rack (that is, outside the side wall) is defined. With such a configuration, the space in the passage is surely partitioned from the external space and airtightness is ensured. Therefore, the cooling space is surely filled into the space in the passage covered with the shield and sucked from the front of the equipment housing rack, so that the cooling efficiency of the equipment housed in the equipment housing rack is enhanced. .

  Specifically, the cooling air sent from the air conditioner to the space in the passage does not return to the air conditioner without cooling the equipment in the equipment storage rack. Further, the heated air blown from the equipment housing rack is prevented from being directly recirculated into the passage space and sucked from the front surface of the equipment housing rack, and is reliably sent to the air conditioner. . Therefore, since the air conditioner can be operated with the minimum necessary air volume, the efficiency of the air conditioner is improved.

  And this shielding body is set as simple installation which has arrange | positioned at least one part of the top wall part on the upper surface of the rack for apparatus accommodation, and has arrange | positioned the lower end part of a side wall part on the floor of a channel | path. Therefore, when installing this shield, unlike the conventional case, it is not easily affected by the layout of the computer room, such as the relative positional relationship between the equipment accommodation rack and other equipment accommodation racks and peripheral equipment. .

  That is, this shielding body can be installed even in the case where the equipment storage rack is disposed only on one side in the width direction of the passage, for example. It can also be installed when the wall surface of the computer room is arranged on the opposite side across the passage of the equipment housing rack. In addition, when the equipment housing racks are arranged opposite to each other with the passage therebetween, the shielding body is also provided in the passage space in the case where the front surface and the rear surface of the equipment housing rack face each other with the passage therebetween. Can be easily defined. In addition, when the equipment storage racks are arranged to face each other across the passage, the length along the extending direction of the passage in the equipment storage rack arranged on one side (the other side) in the width direction of the passage is Even when the length of the equipment storage rack arranged on the other side (one side) in the width direction is set longer than the length, the shield corresponding to the long part of the equipment storage rack The body can be installed easily. In addition, the present invention can be applied to a case other than an installation in which a plurality of equipment-accommodating racks are arranged along a passage and constitute a so-called “line”. In other words, the above-described shielding body can be easily installed even when the rack for housing equipment that generates high heat is singly or randomly installed.

  Furthermore, according to such a configuration of the shield, the size (capacity) of the space in the passage covered by the shield can be freely set. Therefore, for example, the capacity of the passage space can be changed according to the amount of cooling air required for air conditioning design.

Further , the crossing angle formed between the side wall portion and the top wall portion can be adjusted by rotating the side wall portion. Specifically, by rotating the side wall portion around its upper end portion, the floor side end portion (that is, the lower end portion) of the side wall portion approaches and separates from the front surface of the equipment housing rack. Therefore, the side wall portion can be rotated and the position of the lower end portion can be adjusted according to the size (width) of the floor opening portion opened in the floor of the passage.

  When the width of the floor opening is large, the shield covers the floor opening sufficiently by rotating the side wall in a direction away from the front surface of the equipment storage rack. A sufficient amount of cooling air can be taken into the inner space. On the other hand, when the width of the floor opening is small, the capacity of the space in the passage can be reduced by rotating the side wall in a direction approaching the front surface of the equipment housing rack, so that the cooling efficiency is further improved. .

  In the computer room air conditioning system according to the present invention, the side wall portion and the top wall portion may be connected to each other by a hinge member.

  According to the computer room air conditioning system of the present invention, since the side wall and the top wall are connected to each other by the hinge member, the aforementioned angle adjustment can be easily performed. In this case, there is an advantage that the angle adjustment can be freely performed at the site even after the shielding body is installed or when the equipment housing rack is replaced.

  Moreover, the computer room air conditioning system which concerns on this invention WHEREIN: The said side wall part and the said ceiling wall part are good also as mutually connecting through the flexible part which can be plastically deformed.

  According to the computer room air conditioning system of the present invention, the side wall portion and the ceiling wall portion are connected via the flexible portion that can be plastically deformed, so that an external force is applied to the flexible portion to cause plastic deformation. Thus, the angle adjustment described above can be easily performed. Further, in this case, after the angle adjustment described above, fixing such as screwing is not particularly required, so that the workability is excellent.

  Moreover, the computer room air conditioning system which concerns on this invention WHEREIN: The caster member is arrange | positioned by the edge part of the said floor side of the said side wall part.

  According to the computer room air conditioning system of the present invention, since the caster member is disposed at the end of the side wall on the floor side, it is easy to move when installing the shield to the equipment storage rack. It is. Also, in general, equipment storage racks are relatively high and contain heavy communication devices, etc., so that when an earthquake or the like occurs, the top surface is However, according to this configuration, the shield can be installed without being fixed to the floor of the passage. Therefore, when the equipment housing rack vibrates or swings due to an earthquake or the like, the shield is The device accommodating rack moves on the floor so as to correspond to the displacement of the device accommodating rack, so that the device accommodating rack and the shield are prevented from being damaged.

Can be compactly accommodated by winding or overlapping. And when a side wall part is accommodated, work space can fully be ensured in a channel | path.

  Specifically, for example, other equipment accommodation racks and peripheral equipment (hereinafter “other equipment”) are installed on the opposite side across the passage of one equipment accommodation rack provided with a shield. In such a case, at the time of maintenance of other equipment, the side wall portion can be accommodated as necessary to ensure a sufficient working space in the passage. When the maintenance is completed, the side wall portion is returned to the original state, so that the space in the passage and the external space are partitioned again.

Further, since the sheet member on the side wall portion has flexibility as described above, it can be easily deformed and prevented from being damaged when the equipment housing rack and the shield are vibrated or swung due to an earthquake or the like. .
Specifically, for example, a curtain-like sheet member supported by the top wall can be considered as such a side wall. In this case, the sheet member can be folded and compactly accommodated along the passage, and the passage space can be easily opened and closed. Alternatively, the side wall portion may be formed of a roll-shaped sheet member that is supported by the top wall portion and can be accommodated by being wound toward the top wall portion. The space can be easily opened and closed, airtightly shielded, and the side wall portion is less likely to get in the way during work.

The shaft portion 12A is disposed on the upper surface 7B of the equipment accommodating rack 7, and is slidably inserted into the washer 9D of the support member 9. Thereby, the top wall part 12 can be rotated around the shaft part 12 </ b> A with respect to the equipment housing rack 7. Then, as indicated by a two-dot chain line in FIG. 3, each shield 11 can be rotated around each shaft portion 12 </ b> A by the above-described rotation of the top wall portion 12.

  Further, the shaft portion 12A of the top wall portion 12 is detachably connected to the support member 9, and a washer in which the shaft portion 12A is attached to the support member 9 by pushing the top wall portion 12 upward. It can be easily removed from 9D. Thus, the top wall 12 is movable along the width direction of the passage 3 with respect to the top surface 7B in a state where the top wall portion 12 is removed from the top surface 7B of the equipment housing rack 7.

  As shown in FIG. 4, a stopper 12 </ b> B is provided at the approximate center along the width direction of the passage 3 on the lower surface of the top wall 12. When the top wall portion 12 is moved from the front surface 7A side to the rear surface 7D side of the equipment housing rack 7 as described above, the stopper 12B and the front surface 9F facing the passage 3 side of the support member 9 are provided. The movement of the top wall portion 12 is regulated by abutting.

  The side wall 13 of the shield 11 has a substantially rectangular plate shape, and the upper end of the side wall 13 is connected to the end of the top wall 12 that faces away from the device housing rack 7 side. In FIG. 4, the side wall 13 is fixedly supported on the top wall 12 by forming an intersection angle θ with the top wall 12. The intersection angle θ is set in advance corresponding to the dimension (width dimension) along the width direction of the floor opening 5 that opens to the double floor 4. In the present embodiment, the intersection angle θ is 90 °. Has been.

  Specifically, the crossing angle θ can be adjusted by rotating the side wall 13 with respect to the top wall 12 and is fixed to a predetermined angle after the adjustment. And by adjusting the crossing angle θ, the size of the space in the passage 3 can be adjusted, and the lower end portion of the side wall portion 13 can be arranged outside the floor opening 5 in the width direction. Yes. Thereby, the shield 11 is installed so as to sufficiently cover the floor opening 5.

  The distance L between the inner surface 13A facing the passage 3 side of the side wall portion 13 and the front surface 7A of the equipment housing rack 7 can be variously set by adjusting the crossing angle θ as described above. Therefore, for example, when the width dimension of the floor opening 5 of the double floor 4 is large, by turning the side wall portion 13 around its upper end portion and setting the crossing angle θ to an obtuse angle of 90 ° or more, The inner surface 13 </ b> A of the side wall portion 13 extends so as to be gradually separated from the front surface 7 </ b> A of the equipment housing rack 7 as it goes from the upper end portion to the lower end portion, and the lower end portion thereof is closer to the width direction than the floor opening portion 5. Arranged outside.

  As shown in FIG. 1, a pair of caster members 15 made of, for example, a free caster is disposed at the end (lower end) of the side wall 13 on the double floor 4 side. These caster members 15 are arranged at the lower end portion of the side wall portion 13 so as to be separated from each other along the extending direction of the passage 3. A sponge rubber 16 is disposed in the gap between the caster members 15 at the lower end of the side wall portion 13.

Further, as shown in FIG. 5, the caster member 15 is attached to the lower end portion of the side wall portion 13 by screws, for example, and the amount of protrusion protruding from the lower end portion toward the double floor 4 side by screw adjustment is set. Adjustable.
The side wall portion 13 configured as described above can approach and separate from the front surface 7A of the equipment housing rack 7 when the top wall portion 12 is removed from the upper surface 7B of the equipment housing rack 7 as described above. It is said that.

  Further, sponge rubbers (seal portions) 17 are provided between the shields 11 adjacent to each other along the extending direction of the passage 3 to partition the space in the passage 3 and the external space. These sponge rubbers 17 are each formed in a substantially L shape corresponding to the end face of the shield 11 facing the extending direction of the passage 3.

  In other words, the passage 3 is partitioned on one side in the width direction by the front surface 7A of the equipment housing rack 7 and the front surface 9F of the support member 9 thereabove, and on the other side in the width direction by the side wall portion 13 of the shield 11. ing. The passage 3 is partitioned by the top wall 12 of the shield 11 at the top. In this way, the space in the passage 3 is defined and is partitioned from the external space, and airtightness is further secured by the sponge rubbers 16 and 17.

  Further, as shown in FIG. 1, at the end portion along the extending direction of the passage 3, the front surface 7 </ b> A of the device housing rack 7 installed at the end portion, and the shield mounted on the device housing rack 7. 11 and an end cap (end shield) 18 formed corresponding to the cross-sectional shape of the space in the passage 3 surrounded by the double floor 4 is disposed. The end cap 18 has a U-shaped cross-section disposed on the side surface 7E facing the outside in the extending direction of the passage 3 in the equipment accommodating rack 7 and the end surface facing the outside in the extending direction in the shield 11. Alternatively, it includes a frame member 18A having a C-shaped cross section, and a sheet-like cap member 18B that is detachable from the frame member 18A and has flexibility.

  Specifically, the frame member 18A and the cap member 18B of the end cap 18 are airtightly connected by a fastener structure or the like. When the worker accesses the passage 3, the cap member 18B is removed from the frame member 18A or a part thereof is opened so as to enter the passage 3.

  Instead of the end cap 18 described above, a door-like end cap (end shield) 19 that can open and close the passage 3 may be provided corresponding to the cross-sectional shape of the space in the passage 3. . Specifically, the end cap 19 is disposed corresponding to the upper surface 7B of the equipment housing rack 7 and the top wall 12 of the shield 11, and extends along the width direction of the passage 3, and the passage 3 And a door member 19B that can be opened and closed by moving in the width direction along the rail member 19A. When the worker accesses the passage 3, the door member 19 </ b> B is opened so as to enter the passage 3.

In addition, a receiving rubber 20 is arranged to extend in the vertical direction between the side surface 7E of the equipment housing rack 7 disposed at the end along the extending direction of the passage 3 and the door member 19B of the end cap 19. The gap between the side surface 7E and the door member 19B is sealed.
Further, although not particularly illustrated, the end cap configured in this manner may be disposed at the other end opposite to the end along the extending direction of the passage 3.

  Moreover, the air conditioning apparatus 8 is formed in a substantially rectangular parallelepiped box shape. The air conditioner 8 is spaced apart from the side of the equipment housing racks 7 arranged along the passage 3. Specifically, the air conditioning device 8 is spaced apart from the outside of the end cap along the extending direction of the passage 3. Has been placed. The air conditioner 8 sucks and cools the air flowing in the upper space of the computer room 1 from the suction port of the upper surface 8A and then cools it from the blowout port of the lower surface 8B communicating with the internal space 2 of the double floor 4. It is configured to blow out as working air.

  As described above, according to the computer room air conditioning system 10 according to the present embodiment, the top wall 12 of the shield 11 divides the space in the passage 3 and the upper space of the equipment accommodating rack 7, The side wall portion 13 defines a space in the passage 3 and a side space located on the opposite side of the passage 3 from the front surface 7A side of the equipment accommodating rack 7 (that is, outside the side wall portion 13). With such a configuration, the space in the passage 3 is reliably partitioned from the external space and airtightness is ensured. Therefore, the cooling air sent out from the air conditioner 8 is surely filled in the passage 3 covered with the shield 11 and is sucked in from the front surface 7A of the equipment housing rack 7 so as to be filled with the equipment housing rack 7. The cooling efficiency of the equipment housed inside is increased.

  Specifically, the cooling air sent from the air conditioner 8 into the passage 3 is not returned to the air conditioner 8 without cooling the equipment in the equipment housing rack 7. Further, the hot air blown out from the equipment housing rack 7 is prevented from being directly recirculated into the passage 3 and sucked from the front surface 7A of the equipment housing rack 7, and is reliably sent to the air conditioner 8. It is done. Therefore, since the air conditioner 8 can be operated with the minimum necessary air volume, the efficiency of the air conditioner 8 is improved.

  And this shield 11 arrange | positions the edge part by the side of the said back surface 7D of the top wall part 12 on the upper surface 7B of the equipment accommodating rack 7, and the caster member 15 in the lower end part of the side wall part 13 is on the floor of the channel | path 3 It is considered to be a simple installation that is only arranged. Therefore, when the shield 11 is installed, the influence of the layout of the computer room 1 such as the relative positional relationship between the equipment housing rack 7 and other equipment housing racks and peripheral devices as in the prior art. It is hard to receive.

  In other words, the shield 11 can be installed when the equipment accommodating rack 7 is arranged only on one side in the width direction of the passage 3 as in the present embodiment. It can also be installed when the wall surface of the computer room 1 is arranged on the opposite side across the 3. In addition, when the equipment housing racks 7 are opposed to each other with the passage 3 interposed therebetween, the front surface 7A and the back surface 7D of the equipment housing rack 7 face each other with the passage 3 interposed therebetween. The space in the passage 3 can be easily defined by installing the shield 11. In addition, when the equipment-accommodating racks 7 are arranged opposite to each other with the passage 3 therebetween, the extending direction of the passage 3 in the equipment-accommodating rack 7 arranged on one side (the other side) in the width direction of the passage 3 Even when the length along the length is set longer than the length of the equipment storage rack 7 arranged on the other side (one side) in the width direction, the long portion of the equipment storage rack 7 Corresponding to this, the shield 11 of the present embodiment can be easily installed. In addition, the present embodiment can be applied to a case other than an installation in which a plurality of equipment-accommodating racks 7 are arranged along the passage 3 and constitute a so-called “line”. That is, even if the high heat-generating device housing rack 7 is installed alone or randomly, the above-described shield 11 can be easily installed.

  Further, according to such a configuration of the shield 11, the capacity of the space in the passage 3 covered by the shield 11 can be freely set. For example, in the passage 3 according to the amount of cooling air required for air conditioning design. The capacity of the space can be changed.

  In addition, the crossing angle θ formed between the side wall portion 13 and the top wall portion 12 of the shield 11 can be adjusted by rotating the side wall portion 13. Thus, by rotating the side wall part 13, the lower end part of the side wall part 13 can be moved closer to and away from the front surface 7 </ b> A of the equipment housing rack 7. Therefore, the side wall part 13 can be rotated in accordance with the size (width dimension) of the floor opening 5 opened in the floor of the passage 3.

  That is, when the width dimension of the floor opening 5 of the passage 3 is large, the side wall 13 is rotated around its upper end in a direction away from the front surface 7A of the equipment accommodating rack 7, thereby shielding the shield 11. Sufficiently covers the floor opening 5, so that a sufficient amount of cooling air can be taken into the passage 3. On the other hand, when the width dimension of the floor opening 5 of the passage 3 is small, the passage covered with the shield 11 is made by rotating the side wall portion 13 in a direction approaching the front surface 7A of the equipment housing rack 7. Since the capacity of the internal space 3 can be reduced, the cooling efficiency can be further increased.

  Further, since the caster member 15 is disposed at the lower end portion of the side wall portion 13, it is easy to move at the time of installation or the like where the shield 11 is mounted on the equipment housing rack 7. In addition, since the equipment storage rack 7 is relatively high in height as described above and contains a heavy communication device or the like, the upper surface 7B of the equipment storage rack 7 is provided when an earthquake or the like occurs. Although it may be greatly displaced with respect to the floor surface, according to this configuration, the shield 11 can be installed without being fixed to the double floor 4 of the passage 3, so that the equipment accommodating rack 7 is caused by an earthquake or the like. When oscillating or swinging, the shield 11 moves on the floor so as to correspond to the displacement of the equipment housing rack 7, and the equipment housing rack 7 and the shielding body 11 are prevented from being damaged.

  Further, since the caster member 15 can adjust the amount of projection that projects from the lower end portion of the side wall portion 13 toward the double floor 4 side, the caster member 15 reliably contacts the floor surface of the passage 3. In addition, the installation state of the shield 11 is stabilized. Further, when the angle is adjusted by rotating the side wall portion 13 as described above, the distance from the lower end portion of the side wall portion 13 to the floor surface varies, but the protrusion amount of the caster member 15 is adjusted. It can be easily handled.

  The top wall 12 of the shield 11 is detachably connected to the upper surface 7B of the equipment housing rack 7, and the top wall 12 is removed from the upper surface 7B, whereby the side wall of the shield 11 is removed. Since the portion 13 can be moved closer to and away from the equipment housing rack 7, the width of the passage 3 covered by the shield 11 can be easily changed.

  Therefore, for example, when other equipment is installed on the opposite side across the passage 3 of the equipment housing rack 7 provided with the shield 11, it is necessary for maintenance of other equipment. Accordingly, the side wall 13 is brought closer to the front surface 7A of the one device housing rack 7 and the shield 11 is moved toward the one device housing rack 7 so that a work space can be easily secured in the passage 3. . When the maintenance is completed, the side wall portion 13 is separated from the front surface 7A of the single device housing rack 7, and the top wall portion 12 is reconnected to the upper surface 7B of the device housing rack 7 so that the shield 11 is restored. Return to the state.

  Further, since the top wall portion 12 of the shield 11 can be rotated around the shaft portion 12A disposed on the upper surface 7B of the device housing rack 7, the device housing rack 7 vibrates or is caused by an earthquake or the like. When swinging, the top wall portion 12 is rotated around the shaft portion 12 </ b> A with respect to the equipment housing rack 7. According to such a structure, it is suppressed that the shield 11 largely vibrates or swings integrally with the equipment housing rack 7 in the event of an earthquake or the like, and the equipment housing rack 7 and the shield 11 are Damage is prevented.

  The computer room air conditioning system 10 is provided with a plurality of shields 11 along the passage 3, and the space inside the passage 3 and the external space are partitioned between the adjacent shields 11. Since the sponge rubbers 17 are disposed, the cooling air is prevented from leaking from between the shields 11 to the external space, and the space in the passage 3 is efficiently filled. Therefore, the cooling efficiency of the equipment in the equipment housing rack 7 is sufficiently ensured.

  Further, a sponge rubber 16 is disposed in the gap between the caster members 15 at the lower end portion of the side wall portion 13, and the side surface 7 </ b> E and the end cap 19 of the equipment accommodating rack 7 disposed at the end portion along the extending direction of the passage 3. Since the receiving rubber 20 is disposed between the door member 19B and the door member 19B, the airtightness of the space in the passage 3 is sufficiently secured.

  Further, since the end cap 18 is disposed at the end of the passage 3 in the extending direction so as to correspond to the cross-sectional shape of the passage 3, the inner space and the outer space of the passage 3 are surely partitioned. The Therefore, the cooling air filled in the space in the passage 3 leaks into the external space, or the hot air after cooling the equipment in the equipment housing rack 7 is directly recirculated into the passage 3. Is more reliably prevented.

  In addition, since the end cap 18 has a flexible sheet-like cap member 18B, it can be easily deformed and damaged when the equipment housing rack 7 and the shield 11 are vibrated or swung due to an earthquake or the like. Is prevented. Further, when an operator enters the passage 3, the end cap 18 can be attached and detached easily to enter and exit.

  Further, when the end cap 19 capable of opening and closing the passage 3 is provided, the airtightness of the space in the passage 3 can be secured, and the door member 19B can be simply opened and closed along the rail member 19A. The worker can easily access the passage 3.

Next, modified examples of the shield 11 and the support member 9 described in the present embodiment will be described with reference to FIGS. 6 and 7.
In the modification shown in FIG. 6, the support member 9 is mounted on the upper surface 7 </ b> B of the equipment housing rack 7. As an alternative to the shaft portion 12A described above, an elastic hinge member that connects an end surface of the top wall portion 12 of the shield 11 facing the back surface 7D side and an end surface of the horizontal member 9B of the support member 9 facing the back surface 7D side. A pair of 21 is provided.

  These elastic hinge members 21 are made of an elastically deformable material such as an elastomer, and are spaced apart from each other along the extending direction of the passage 3 and are fixed to the top wall portion 12 and the support member 9 by screws or the like. Has been. Thus, the top wall 12 is connected to the upper surface 7B of the equipment accommodating rack 7 via these elastic hinge members 21.

  According to such a configuration, the shield 11 is rotatable so as to open and close the passage 3 around the elastic hinge member 21. In the event of an earthquake or the like, the elastic hinge member 21 that connects the equipment-accommodating rack 7 and the shield 11 acts to be elastically deformed to absorb vibrations or swings, and the equipment-accommodating rack 7 and the shield. As a result, the apparatus housing rack 7 and the shield 11 are prevented from being damaged.

  Further, in this case, when the earthquake or the like is subsided, the posture (position) of the shield 11 with respect to the equipment housing rack 7 is restored to the original state by the elastic restoring force of the elastic hinge member 21, so that the recovery work after the earthquake or the like can be performed. Easy. In addition, when removing the shield 11 from the equipment-accommodating rack 7, a screw or the like for fixing the elastic hinge member 21 may be removed.

  Further, in the modification shown in FIG. 7, an adapter member 22 having a U-shaped cross section or a C-shaped cross section is detachably attached to the top of the support member 9 described in the modified example of FIG. And instead of fixing the elastic hinge member 21 to the end surface of the support member 9 on the back surface 7D side, the adapter member 22 is fixed to the end surface of the back surface 7D side. In this case, the top wall 12 of the shield 11 can be easily attached to and detached from the top surface 7B of the equipment housing rack 7, and the movement in the width direction with respect to the top surface 7B of the top wall 12 can also be performed easily. .

(Second Embodiment)
Next, a computer room air conditioning system 30 according to a second embodiment of the present invention will be described with reference to FIGS.
