JP 2011-220877 A

Here, construction of an information processing equipment room with a low ceiling height has been demanded mainly for cost reduction. 5A and 5B are side views schematically showing a heat pool in the information processing equipment room, where FIG. 5A is a conventional information processing equipment room with a ceiling height, and FIG. 5B is an information processing equipment room with a low ceiling height. It is. However, as shown in FIG. 5, when the ceiling height of the information processing equipment room is lowered, there is a possibility that a heat pool is generated near the ceiling of the information processing equipment room due to exhaust heat of the information processing equipment. When a heat pool is generated in this way, it is conceivable that the heat pool does not stay only in the vicinity of the ceiling, but moves or diffuses to some extent that can affect the information processing device. In such a case, the information processing device is exposed to a high temperature, resulting in a risk of malfunction or failure of the information processing device, a risk of reducing the cooling efficiency of the information processing device, and an increase in the processing load of the cooling coil. The risk of increasing may be increased, which was not preferable.
In addition, assuming that the temperature distribution in the information processing equipment room is not uniform (that is, assuming the occurrence of heat pools), the set temperature is lowered as a whole in accordance with the part that is likely to be in the high temperature range. Although it is conceivable to maintain the environmental conditions, the entire chamber is excessively cooled, which is not preferable. In view of the above points, there has been a demand for an air conditioning system capable of preventing the generation of heat pools near the ceiling of the information processing equipment room.

  Further, the air conditioning system 100 according to the related art needs to install the cooling coil 120 not only in the duct area 103 but also in the UPS chamber 104 in order to process the exhaust heat of the UPS 140. Therefore, the number of installed cooling coils 120 increases, the number of refrigerant supply pipes (not shown) for supplying refrigerant to the cooling coils 120 increases, and it is necessary to secure an installation space for the cooling coils 120 in the UPS chamber 104. was there.

  Therefore, even when a space to be cooled with a relatively low ceiling height (corresponding to the information processing equipment room 101 in the prior art) is constructed, it is possible to prevent the accumulation of heat and the auxiliary ventilation space ( There has been a demand for an air conditioning system that can reduce the cooling means (cooling coil 120 in the prior art) that needs to be installed in the UPS chamber 104 in the prior art.

  The present invention has been made in view of the above, and even when a cooling target space having a relatively low ceiling height is constructed, it is possible to prevent the occurrence of heat accumulation and an auxiliary air blowing space. Even if it is subject to heat treatment (for example, when equipment with exhaust heat such as UPS is installed in the auxiliary ventilation space), it is possible to reduce the cooling means required to install in the auxiliary ventilation space Is to provide a simple air conditioning system.

  In order to solve the above-described problems and achieve the object, the air conditioning system according to claim 1 is adjacent to a cooling target space including a device to be cooled along a predetermined direction with respect to the cooling target space. And the cooling space that is arranged so as to allow the space to be cooled and the ventilation space to communicate with each other and that cools the air. An air conditioning system that cools the equipment by forming a flow of air that circulates to the cooling space sequentially through the space and the space to be cooled, and is disposed in the cooling space to reduce the flow of air. An air blowing unit to be formed; a cooling unit arranged in the cooling space for cooling air; and an auxiliary air blowing space arranged to communicate the cooling target space and the ventilation space with each other. Auxiliary air blowing means that forms an air flow from the ventilation space through the auxiliary air blowing space to a heat storage region in which heat of the device accumulates in the space to be cooled. .

  The air conditioning system according to a second aspect is the air conditioning system according to the first aspect, wherein the auxiliary air blowing space is a space in which a power supply device that supplies power to the device is arranged.

  The air conditioning system according to a third aspect is the air conditioning system according to the first or second aspect, wherein the auxiliary air blowing space is disposed at a position facing the cooling space with the cooling target space and the ventilation space interposed therebetween.

According to the air conditioning system of claim 1, since the air flow from the ventilation space to the heat storage area of the space to be cooled is formed through the auxiliary ventilation space, the cooling air is blown to the heat storage area, so that the ceiling height is increased. Even when a relatively low cooling target space is constructed, it is possible to prevent the accumulation of heat and to move the device to a high temperature environment due to the movement or diffusion of heat accumulation to some extent to the extent that the heat accumulation affects the device. It is possible to reduce the possibility of being exposed, and to reduce the risk of malfunction or failure of the device, the risk of reducing the cooling efficiency of the device, and the risk of increasing the processing load of the cooling means.
In addition, even if the auxiliary air blowing space is a target of heat treatment, the cooling means installed in the cooling space can also be used for heat treatment of the auxiliary air blowing space to reduce the cooling means that need to be installed in the auxiliary air blowing space. Compared with the case where a dedicated cooling means for the heat treatment is installed in the auxiliary air blowing space, it is possible to reduce the number of cooling means installed, and consequently, the auxiliary air blowing space can be saved.

  According to the air conditioning system of the second aspect, since the auxiliary air blowing space is a space where the power supply device is arranged, the exhaust heat of the power supply device is processed by the cooling means arranged in the cooling space, and the auxiliary air blowing space. In addition, it is possible to perform exhaust heat processing of the power supply device without installing other cooling means, and it is possible to reduce the number of cooling means installed, which in turn makes it possible to save space in the auxiliary air blowing space. .

  According to the air conditioning system of the third aspect, since the auxiliary air blowing space is arranged at a position facing the cooling space across the cooling target space and the ventilation space, it is the farthest position from the cooling space in the cooling target space, It is possible to form an air flow at a position where the heat of the device easily accumulates, and it is possible to further prevent the accumulation of heat in the space to be cooled.

Each rack 6 constituting the rack row is arranged such that the direction of the suction surface and the direction of the blowing surface are aligned. In addition, a plurality of such rack rows (four rows in the present embodiment) are arranged in parallel along a direction (in the present embodiment, the width direction) orthogonal to the specific direction. The plurality of rack rows are arranged so that the respective suction surfaces and the blow-out surfaces face each other, and the space thus provided on the suction surface side of the rack rows is referred to as “cold aisle”. The space provided on the blowing surface side of the row is referred to as “hot aisle” and will be described below. In addition, a capping material may be provided from the upper end of each rack row to the ceiling material of the chamber 2 to be cooled, and the air of the cold aisle flows into the hot aisle without passing through the inside of the rack 6 by this capping material. This can be prevented and the cooling efficiency of the information processing device can be improved.

  Here, a connection hole (not shown) for connecting the cold aisle and the ventilation chamber 3 is formed in the floor material of the chamber 2 to be cooled, and the air in the ventilation chamber 3 is passed through the connection hole to the cold aisle. It is configured to be flowable.

  The ventilation chamber 3 is a ventilation space arranged so as to be adjacent to the cooling target chamber 2 along a predetermined direction (the height direction in the present embodiment), and is cooled in the cooling chamber 4. This is a space for allowing air to flow to the cooling target chamber 2 through the ventilation chamber 3. In the present embodiment, as shown in FIG. 1, the ventilation chamber 3 and the UPS chamber 5 are described as being integrally formed without being separated from each other by an inner wall or the like. The configuration is not limited to this as long as the configuration allows air to flow into the UPS chamber 5. For example, the ventilation chamber 3 and the UPS chamber 5 may be separated by an inner wall or the like, and a plurality of ventilation holes (not shown) for connecting the ventilation chamber 3 and the UPS chamber 5 to each other may be provided on the inner wall. Moreover, although the utilization use of this ventilation chamber 3 is arbitrary, you may utilize as space for performing the maintenance inspection of the information processing apparatus arrange | positioned in the chamber 2 to be cooled, for example.

  The cooling chamber 4 is a cooling space in which the cooling coil 10 cools the air, and is arranged so that the cooling target chamber 2 and the ventilation chamber 3 communicate with each other. Here, in this cooling chamber 4, a plurality of (six in this embodiment) cooling coils 10 and blower fans 20 are arranged along the width direction, and the cooling chamber 4 is secured by a known method such as screwing. It is fixed to the inner wall. A plurality of (three in the present embodiment) openings 11 a are provided along the width direction on the inner wall that partitions the cooling target chamber 2 and the cooling chamber 4. A plurality of (three in the present embodiment) openings 11b are provided along the width direction on the inner wall that partitions the two.

(Configuration-air conditioning system)
Then, each component which comprises the air conditioning system 1 is demonstrated.

(Configuration-Air conditioning system-Cooling coil)
The cooling coil 10 is a cooling unit that is disposed in the cooling space and cools the air. The cooling coil 10 is installed on the suction surface side of the blower fan 20 and is a known cooler that cools the air taken into the blower fan 20. Means. Here, the specific configuration of the cooling coil 10 is arbitrary, but in the present embodiment, a known refrigerant that cools air using a refrigerant supplied via a refrigerant supply pipe (not shown). The description will be made assuming that the coil is a coil. In addition, this refrigerant | coolant supply pipe | tube is a refrigerant | coolant supply means which supplies a refrigerant | coolant with respect to the cooling coil 10, Comprising: It is comprised as a hollow annular body formed with the metal, resin, etc. The specific configuration of the refrigerant supply pipe is arbitrary. For example, the refrigerant supply pipe is connected to a cooling tower (not shown) disposed in a space outside the information processing facility, and is cooled by the cooling tower. The well-known structure which supplies the cooled water to the cooling coil 10 as a refrigerant | coolant is employable. As described above, in the present embodiment, description is made on the assumption that cooling water is used as the refrigerant. However, other refrigerants may be used, for example, steam or gas may be used. Further, the number of cooling coils 10 installed may be different depending on the size of the cooling target chamber 2, the heat generation amount of the information processing device, the heat generation amount of the UPS 30, and the like in the present embodiment, but along the width direction. The explanation will be made assuming that 6 units are arranged in parallel.

(Configuration-Air conditioning system-Blower fan)
The blower fan 20 is a blower unit that forms a flow of air, and the number of the blower fans 20 is arbitrary. In the present embodiment, a total of six blower fans 20 are juxtaposed along the width direction. Explain that it is. In the following description, it is assumed that one of these is used as a spare blower fan 20 and is used when another blower fan 20 fails. Here, the specific installation method of each blower fan 20 is arbitrary. For example, in a state in which the suction surface faces upward and the blowout surface faces downward, the cooling chamber 4 is fixed by a known method such as screwing. It demonstrates as what is fixed to the inner wall etc. In the blower fans 20 thus formed, each blower fan 20 sucks air above the cooling chamber 4 and blows it downward to form an air flow.

(Configuration-Air conditioning system-UPS)
The UPS 30 is power supply means for supplying power to the information processing device, and is disposed in the UPS room 5. The UPS 30 can be configured as a power supply device such as a known uninterruptible power supply device, but its specific configuration is known and will not be described in detail.

(Configuration-Air conditioning system-Auxiliary fan)
The auxiliary fan 40 is auxiliary air blowing means that forms an air flow from the ventilation chamber 3 through the UPS chamber 5 to the heat storage region 50 of the cooling target chamber 2. Specifically, the auxiliary fan 40 is provided in a pipe route installed from the vicinity of the ceiling of the UPS chamber 5 to the inner wall between the cooling target chamber 2 and the UPS chamber 5. Here, the end on the UPS chamber 5 side in this pipe will be referred to as a suction port 41, and the end on the cooling target chamber 2 side will be referred to as a blow-out port 42, and will be described below. The auxiliary fan 40 sucks air in the vicinity of the ceiling of the UPS chamber 5 from the suction port 41 and blows it out from the blowout port 42 to the chamber 2 to be cooled, so that the auxiliary fan 40 passes through the UPS chamber 5 from the ventilation chamber 3. A flow of air reaching the cooling target chamber 2 is formed. In this way, by causing air to flow into the heat storage region 50 in the cooling target chamber 2, it is possible to prevent the accumulation of heat in the cooling target chamber 2. Note that the “heat storage area” 50 is an area in which heat of the information processing device is particularly accumulated, and includes, for example, a hot aisle and the vicinity of the ceiling of the cooling target chamber 2.

  In addition, as long as the above air flows can be formed, the position of the air outlet 42 is arbitrary. However, in the present embodiment, as shown in FIG. 1, it is formed at a position in the vicinity of the center in the height direction of the cooling target chamber 2 and on the extension line of the hot aisle as shown in FIG. It is assumed that air is blown from the outlets 42 along the extending direction of the rack 6. The direction in which the air outlet 42 blows air is arbitrary. For example, the air may be blown obliquely upward, but in the present embodiment, the air is blown out in the horizontal direction. Moreover, you may comprise the blower outlet 42 so that the position and blowing direction of the blower outlet 42 can be suitably changed according to the generation | occurrence | production state of a heat pool, etc. Further, the specific configuration of the auxiliary fan 40 is arbitrary, and for example, it can be formed as a known fan in the same manner as the blower fan 20 described above.

(Air conditioning treatment)
Next, an air conditioning process executed by the air conditioning system 1 configured as described above will be described.

  First, the blower fan 20 provided in the cooling chamber 4 sucks air from above in the cooling chamber 4 and blows out air downward in the cooling chamber 4. As a result, as shown in FIG. 1, air circulates to the cold aisle sequentially through the cold aisle, the inside of the rack 6, the hot aisle, the opening 11 a, the cooling chamber 4, the opening 11 b, and the ventilation chamber 3. To do. The auxiliary fan 40 provided in the UPS chamber 5 sucks air in the vicinity of the ceiling of the UPS chamber 5 from the suction port 41 and blows air from the blowout port 42 to the cooling target chamber 2. As a result, as shown in FIG. 1, air flows from the ventilation chamber 3 to the cooling target chamber 2 through the UPS chamber 5, the suction port 41, and the air outlet 42 in order.

  Here, first, the air taken into the cold aisle from the ventilation chamber 3 cools the information processing device by passing through the inside of the rack 6, and is heated by the heat generated by the information processing device at this time to be a high temperature (for example, , 30 ° C.) and incorporated into hot aisle. Further, the air taken into the UPS chamber 5 from the ventilation chamber 3 cools the UPS 30, and becomes a high temperature (for example, 24 ° C.) heated by the heat generated by the UPS 30 at this time. It is taken into the hot aisle through the air outlet 42. That is, the air that has passed through mutually different paths, that is, the air that has passed through the inside of the rack 6 and the air that has passed through the suction port 41 and the air outlet 42 is taken into the hot aisle.

  Then, the air taken into the hot aisle is taken into the cooling chamber 4 through the vicinity of the ceiling of the chamber 2 to be cooled and the opening 11a sequentially, and is cooled by the cooling coil 10 of the cooling chamber 4 to be cooled to a low temperature (for example, 18 ° C). And the air cooled in this way is taken in into the ventilation chamber 3 through the opening part 11b. Then, the air taken into the ventilation chamber 3 in this way is the air taken into the cold aisle again through the connection hole provided in the floor of the chamber 2 to be cooled, and the air taken into the UPS chamber 5 again. It is divided into. The air taken into the cold aisle again passes through the inside of the rack 6 to cool the information processing equipment, and the air taken into the UPS room 5 again passes through the inlet 41 and the outlet 42 again. By blowing air to the cooling target chamber 2, this contributes to prevention of heat accumulation in the heat storage region 50. Thereafter, similarly, as described above, the information processing device is cooled by the air flowing in the rooms of the information processing facility.

  In this way, by installing the auxiliary fan 40 in the auxiliary air blowing space, it is possible to simultaneously achieve the prevention of heat accumulation in the information processing equipment room and the reduction of the cooling means installed in the auxiliary air blowing space.

  In the present embodiment, the UPS chamber 5 is disposed at a position facing the cooling chamber 4 with the cooling target chamber 2 and the ventilation chamber 3 interposed therebetween, and the air outlet 42 is an opening in the cooling target chamber 2. 11a is provided on the inner wall at a position opposite to the inner wall provided with 11a. In this manner, by providing the air outlet 42 at a position farthest from the opening 11a where heat accumulation is likely to occur, the cooling air can be efficiently blown to the heat storage region 50, and generation of heat accumulation is further reduced. This can be further prevented. This is the end of the description of the air conditioning process by the air conditioning system 1.

(Effect of embodiment)
As described above, according to the present embodiment, since the air flow from the ventilation chamber 3 to the heat storage region 50 of the cooling target chamber 2 through the UPS chamber 5 is formed, the cooling air is blown to the heat storage region 50. Even when the cooling target room 2 having a relatively low ceiling height is constructed, it is possible to prevent the generation of heat pool and to move or diffuse to some extent to which the heat pool affects the information processing equipment. The possibility of the information processing device being exposed to a high temperature environment can be reduced, the risk of malfunction or failure of the information processing device, the risk of reducing the cooling efficiency of the information processing device, and the increase in the processing load of the cooling coil 10 Risk can be reduced.
Further, even when the UPS chamber 5 is a target of heat treatment, the cooling coil 10 installed in the cooling chamber 4 can also reduce the cooling means that needs to be installed in the UPS chamber 5 by using the heat treatment of the UPS chamber 5. As a result, the number of cooling means installed can be reduced as compared with the case where a dedicated cooling means for the heat treatment is installed in the UPS chamber 5, and thus the space of the UPS chamber 5 can be saved.

  Further, since the UPS chamber 5 is a space in which the power supply device is arranged, the exhaust heat of the power supply device is processed by the cooling coil 10 arranged in the cooling chamber 4, and another cooling coil 10 is installed in the UPS chamber 5. Therefore, the exhaust heat treatment of the UPS 30 can be performed without reducing the number of cooling units installed, and thus the space in the UPS room 5 can be saved.

  In addition, since the UPS chamber 5 is disposed at a position facing the cooling chamber 4 with the cooling target chamber 2 and the ventilation chamber 3 interposed therebetween, the UPS chamber 5 is the farthest position from the cooling chamber 4 in the cooling target chamber 2 and the heat of the information processing device. Therefore, it is possible to form an air flow at a position where it is easy to accumulate, and to further prevent the accumulation of heat in the cooling target chamber 2.

In addition, although the number of the modules 61 is arbitrary, in this modification, the complex type air conditioning system 60 in which six modules 61 are arranged is illustrated. Here, each module 61 may be devised so that the UPS 30 and the cooling room 4 are aggregated so that the flow line of the administrator of the UPS 30 and the flow fan 20 or the cooling coil 10 does not intersect. desirable. Specifically, as shown in FIG. 3, the modules 61 are arranged side by side in the same direction along the width direction and are arranged side by side in the symmetrical direction along the depth direction, thereby collecting the UPS chambers 5 of the modules 61. In addition, by forming a passage 62 that communicates with each UPS room 5 between the UPS rooms 5, it is possible to collect the flow lines of the manager. Thus, by forming the composite air conditioning system 60 by arranging a plurality of modules 61 in parallel, the composite air conditioning system 60 suitable for the number of information processing devices to be cooled, the amount of heat generation, and the like is configured. It becomes possible to do.

(About the blower fan)
In this Embodiment, although demonstrated as what arrange | positions the ventilation fan 20 only in the cooling chamber 4, it is not limited to this. For example, a ventilation fan 20 that blows air toward the cold aisle may be added inside the ventilation chamber 3 to increase the power of blowing as a whole.

(Appendix)
The air conditioning system according to appendix 1 includes a cooling target space including a device to be cooled, a ventilation space arranged to be adjacent to the cooling target space along a predetermined direction, the cooling target space, and the cooling target space. A cooling space arranged to communicate the ventilation space with each other, wherein the cooling space is configured to cool the air from the cooling space to the cooling space sequentially through the ventilation space and the space to be cooled. An air-conditioning system that cools the equipment by forming a circulating air flow, and a blower unit that is arranged in the cooling space to form the air flow; A cooling means for cooling, and auxiliary air blowing means installed in an auxiliary air blowing space arranged to communicate the space to be cooled and the ventilation space with each other, from the ventilation space Via the serial auxiliary blowing space and a supplementary blowing means the heat of the device to form a flow of air leading to the heat storage region for storing in said space to be cooled.

  The air conditioning system according to attachment 2 is the air conditioning system according to attachment 1, wherein the auxiliary air blowing space is a space in which a power supply device that supplies power to the device is arranged.

  The air conditioning system according to appendix 3 is the air conditioning system according to appendix 1 or 2, wherein the auxiliary air blowing space is disposed at a position facing the cooling space with the cooling target space and the ventilation space interposed therebetween.

(Additional effects)
According to the air conditioning system described in appendix 1, the air flow from the ventilation space to the heat storage area of the space to be cooled is formed via the auxiliary air blowing space. Even when a relatively low cooling target space is constructed, the generation of heat accumulation is prevented, and the equipment is exposed to a high temperature environment due to the movement or diffusion of heat accumulation to some extent to the extent that the heat accumulation affects the equipment. It is possible to reduce the risk of device malfunction and failure, the risk of reducing the cooling efficiency of the device, and the risk of increasing the processing load of the cooling means.
In addition, even if the auxiliary air blowing space is a target of heat treatment, the cooling means installed in the cooling space can also be used for heat treatment of the auxiliary air blowing space to reduce the cooling means that need to be installed in the auxiliary air blowing space. Compared with the case where a dedicated cooling means for the heat treatment is installed in the auxiliary air blowing space, it is possible to reduce the number of cooling means installed, and consequently, the auxiliary air blowing space can be saved.

  According to the air conditioning system described in appendix 2, since the auxiliary air blowing space is a space where the power supply device is arranged, the exhaust heat of the power supply device is processed by the cooling means arranged in the cooling space, and the auxiliary air blowing space is formed. The exhaust heat processing of the power supply device can be performed without installing other cooling means, the number of installed cooling means can be reduced, and the space for the auxiliary ventilation space can be saved.

  According to the air conditioning system described in appendix 3, the auxiliary air blowing space is disposed at a position facing the cooling space with the cooling target space and the ventilation space interposed therebetween, and is therefore the farthest position from the cooling space in the cooling target space. Therefore, it is possible to form an air flow at a position where the heat is easily accumulated, and to further prevent the accumulation of heat in the space to be cooled.
