  By the way, recent information communication equipment includes standard information communication equipment that is guaranteed to operate in a standard temperature range of about 15 ° C. to 27 ° C., and high temperature durable information communication that is guaranteed to operate in a temperature range higher than 35 ° C. There is equipment. The high temperature durable information communication equipment can be operated without any problems even in a higher temperature environment than before, and by adopting this, the air temperature of the air conditioning equipment can be set high, and accordingly In order to save air-conditioning energy, it is expected that the use of high-temperature durable information communication equipment will increase in the future.

  However, at present, standard information communication devices are installed in most server rooms, and it is not realistic to immediately replace all of these with high temperature durable information communication devices. As a result, some existing standard information and communication equipment will be gradually replaced with high-temperature and durable information and communication equipment, and in reality, the standard information and communication equipment and high-temperature and durable information and communication equipment will coexist in the server room. Can be considered.

  If it summarizes in this point, in the technique of patent document 1, when air-conditioning the room where standard information communication equipment and high temperature endurance information communication equipment coexist, when supplying the conditioned air of the temperature according to standard information communication equipment, For high temperature durable information and communication equipment, excessively low temperature air is supplied, which wastes energy. On the other hand, if conditioned air having a temperature suitable for the high temperature durable information communication device is supplied, operation of the standard information communication device is hindered. In order to prevent these problems, there is a problem that a room must be partitioned into a standard information communication equipment area and a high temperature durable information communication equipment area, and a system for supplying conditioned air having a temperature suitable for each of them must be constructed. In this case, it is preferable to minimize the layout change.

  The present invention has been made in view of such a point, and aims to cool each information communication device more efficiently in a room where the standard information communication device and the high temperature durable information communication device as described above coexist, Another object of the present invention is to minimize layout changes when a standard information communication device and a high temperature durable information communication device coexist in a room in which an existing standard information communication device is in operation.

In order to achieve the above object, the present invention includes a standard information communication device having an intake surface on the front side and an exhaust surface on the back side and guaranteed to operate in a standard temperature range, and an intake surface on the front side and a back side. An air conditioning system for a room containing an exhaust surface and a high temperature durable information communication device that is guaranteed to operate up to a temperature range higher than the standard temperature range,
Standard equipment row arranged in a row so that the front side of the standard information communication equipment is on the same side, and high temperature endurance arranged in a row so that the front side of the high-temperature information communications equipment is on the same side The high temperature durable device row is arranged so that the front side of the high temperature durable device row faces in a space where the device row is arranged on the same row and exhaust from the back side of the standard device row is exhausted,
It has an air conditioner that takes in the exhaust from the high temperature durable equipment row as return air and supplies it to the front side space of the standard equipment row in the room as supply air.
Here, the standard equipment row and the high-temperature durable equipment row are the standard equipment and the high-temperature durable equipment itself stacked in multiple layers, or the standard information communication equipment and the high-temperature durable information communication equipment that are tall are arranged in the horizontal direction. In addition to the case of forming a row, it may be a case where it is mounted on a rack to form a rack row of standard equipment, a rack row of high temperature durable equipment, or a mixed form thereof. Good. Further, the front side space of the standard equipment row to which the air supply from the air conditioner is supplied includes not only the front side space but also a space communicating with the front side space, for example, a side space of the standard equipment row. .

  According to the present invention, the air supply from the air conditioner supplied to the front side space of the standard equipment row is sucked from the intake surface by the small fan included in the standard information communication equipment of the standard equipment row, After cooling, the temperature is raised and exhausted to the back side space. And since the front side of the high temperature durable device row, that is, the intake surface side faces this back side space, the air in the back side space is provided in the high temperature durable information communication device of the high temperature durable device row. The air is sucked from the intake surface by a small fan, and after cooling the device, the temperature is further raised and exhausted to the back side space. The operation of the high temperature durable information communication equipment is guaranteed in a temperature range higher than the standard temperature range, so the air taken in by the high temperature durable information communication equipment is higher in temperature than the air taken in by the standard information communications equipment, that is, Even air that has passed through the standard equipment line that the standard information communication equipment exhausts to the back side can be used for cooling the high temperature durable information communication equipment, and there is no problem in the operation of the high temperature durable information communication equipment. Therefore, the air supply from the air conditioner can be efficiently used for cooling the standard information communication device and the high temperature durable information communication device. In addition, because the standard equipment row and the high temperature durable equipment row are arranged on the same row, the layout flexibility is high, and the high temperature durable equipment row is introduced to the existing room that accommodates only the standard equipment row. Or even partially replace it without changing the basic layout.

  The space to which the air supply from the air conditioner is supplied and the back side space of the high temperature durable device row may be partitioned by a partition material.

  Moreover, the space where the air supply from the air conditioner is supplied and the space where the exhaust from the back side of the standard equipment row is exhausted may be partitioned by a partition material.

  A bypass part for introducing the supply air may be provided in a space in which exhaust from the back side of the standard device row is exhausted without passing through the standard device row from the front side space of the standard device row. Good.

  Other than introducing the air in the front side space of the high temperature durable device row from the front side space of the high temperature durable device row into the back side space of the high temperature durable device row without passing through the high temperature durable device row You may have a bypass part. The bypass part is not only a closed system flow path in which the spaces communicated with each other by a duct or the like, for example, each space is adjacent and there is no partition between them, or an opening is provided in a partitioning member, etc. It may be an open air flow path.

  These bypass units may be provided with an air volume adjustment mechanism or a backflow prevention mechanism. By doing so, it is possible to prevent the high temperature air from the high temperature region side from flowing to the low temperature region side. Examples of the air volume adjusting mechanism include an air volume adjusting damper VD and a motor damper MD, and the adjustment of the opening degree of these mechanisms may be either manual or automatic. Examples of the backflow prevention mechanism include a slight differential pressure damper and a backflow prevention damper. In order to realize simply, for example, by opening in vinyl and providing another piece of vinyl so as to cover the opening, a function of preventing backflow can be obtained. In addition, about an open-type bypass flow path, an opening should be formed in the part of a partition material, and such a backflow prevention mechanism should just be provided in the said opening part. Furthermore, the bypass portion has an opening degree according to the differential pressure between the front side space of the standard device row, the front side space of the high temperature durable device row, and the back side space of the high temperature durable device row. A flow rate adjusting mechanism for adjusting the flow rate may be provided. In the case of a closed system flow path such as a duct, a variable damper may be provided in the duct. For the open bypass channel, an opening may be formed in the partition member, and for example, a shutter, a door body, or the like whose opening degree is variable may be provided in the opening.

  A part of the air in the space where the exhaust from the back side of the standard equipment row is exhausted may be directly taken into the air conditioner.

  Exhaust gas from the high-temperature durable device row may be configured to be taken into the air conditioner as return air after being cooled through a device for using waste heat.

  The supply air volume of the air supply of the air conditioner is the total intake air volume of all standard information communication devices installed in the standard equipment row, and all the high temperature durable information communication devices installed in the high temperature durable device row. It may be controlled to be larger than the total intake air volume.

  According to the present invention, in a room where standard information communication equipment and high-temperature-resistant information communication equipment coexist, it is possible to cool information communication equipment more efficiently and efficiently than the conventional information communication equipment. It is also possible to minimize layout changes when standard information communication equipment and high-temperature tolerant information communication equipment coexist in a room that accommodates existing standard information communication equipment in operation. .

  Hereinafter, an air conditioning system for a room accommodating information communication equipment according to an embodiment will be described. FIG. 1 schematically shows a plane of the air conditioning system 1 according to the embodiment. Standard device rows SL1 and SL2 in which racks 10 in which standard information communication devices such as servers, which are guaranteed to operate in a temperature range, for example, 15 ° C. to 27 ° C. are arranged in multiple stages, are arranged in the longitudinal direction. They are arranged in parallel. Each standard equipment row SL1, SL2 is arranged so that the back side (exhaust side) of the standard information communication equipment mounted on the rack 10 faces each other. In the example shown in FIG. 1, for convenience of explanation, a state in which two standard device rows SL1 and SL2 are arranged in the room R is shown. Of course, the present invention is arranged in such a two-row arrangement. However, the standard information communication devices mounted on the rack 10 are arranged so that the back surfaces (exhaust side) and the front surfaces (suction side) face each other, thereby arranging two or more standard device rows SL. The present invention can also be applied to an example (for example, an arrangement in which a plurality of modes of the air conditioning system 1 are arranged in the vertical direction in FIG. 1 with the standard device rows SL in parallel).

  The standard information communication device sucks the air on the front side by a small fan (not shown) and uses it to cool each standard information communication device, and then exhausts the heated air to the back side. It is like that.

  Bypass portions 30, 31 and a space at one end (right end in FIG. 1) of the standard equipment rows SL1 and SL2, operate in a temperature range higher than the standard temperature range, for example, 35 ° C. or higher. The high-temperature durable device rows HL1 and HL2 in which the racks 20 in which the guaranteed high-temperature durable information communication devices are mounted in multiple stages are arranged in the longitudinal direction are parallel to each other in a space, and the standard device row SL1 and the high-temperature durable device The row HL1, the standard equipment row SL2, and the high temperature durable equipment row HL2 are installed so as to be located on the same row. And the bypass parts 40 and 41 are each arrange | positioned at the one end part (right side edge part in a figure) of each high temperature durable apparatus row | line HL1 and HL2.

  As viewed from the longitudinal path (here, hot aisle H) that separates the opposing racks, each high temperature durable equipment row HL1, HL2 has a front side (intake side) of the high temperature durable information equipment mounted on the rack 20. They are arranged so that they face each other. That is, the standard device row SL1 and the high-temperature durable device row HL1, and the standard device row SL2 and the high-temperature durable device row HL2 are arranged in the same row, but for the mounted communication devices, the standard device rows SL1 and SL2 The standard information communication equipment mounted on the rack 10 is arranged so that the back surfaces (exhaust sides) face each other, whereas the high temperature durability mounted on the rack 20 of the high temperature durable equipment row HL1, HL2. The information communication devices are arranged so that the front surfaces (intake side) face each other.

In the example shown in FIG. 1, for convenience of explanation, a state in which two rows of high-temperature durable device rows HL1 and HL2 are arranged in the room R is shown. For example, a high temperature durable device row may be provided behind the high temperature durable device row HL1 and the high temperature durable device row HL2. Even in an example in which two or more high-temperature durable device rows HL are arranged by arranging the high-temperature durable information communication devices mounted on the rack 20 so that the front surfaces (suction side) and the back surfaces (exhaust side) face each other. There is application.
For convenience of explanation, a portion where high-temperature exhaust heat gathers as Super Hot Isle SH is expressed as “Isle”, but the same space (area) in the rack containing the high temperature durable information communication device or in the upper part of the rack And the space may be returned to the RA or heat exchanger as a part where high-temperature exhaust heat is collected.

  An air conditioning machine room M is provided at one end wall of the room R, and air conditioners 2 and 3 such as package air conditioners are installed in the air conditioning machine room M, and the return air from the room R is taken in. Then, the temperature is lowered by a direct expansion coil or the like of the refrigerant, and then supplied into the chamber R as the supply air SA. In this example, the supply air SA is supplied to the other end side space of the standard device rows SL1 and SL2. Therefore, the front side space of the standard equipment rows SL1 and SL2 and the space between the standard equipment rows SL1 and SL2 and the machine room M are formed by the supply air SA, for example, about 25 ° C. A “U” -shaped cold aisle C is formed. The supply route of the supply air SA from the air conditioners 2 and 3 can be a known technique applied to this type of so-called server room. For example, supply from the floor surface through the underfloor space, supply from the ceiling surface through the ceiling back space, supply from the supply port formed in the wall surface of the room R, and the like can be employed. This also applies to the embodiments described later.

  The air of the cold aisle C is sucked from the front and back sides by a small fan (not shown) of a standard information communication device mounted on the rack 10 of the standard device rows SL1 and SL2, and is used for cooling the standard information communication device. After the temperature rises, the air is exhausted to the back surface (exhaust side), that is, the space between the standard device rows SL1 and SL2. Therefore, a hot aisle H of about 35 ° C. is formed in the space between the standard device rows SL1 and SL2. Since this hot aisle H communicates with the space between the high temperature durable equipment rows HL1 and HL2, the air of this hot aisle H is the high temperature durable information mounted on the rack 20 of the high temperature durable equipment rows HL1 and HL2. A small fan (not shown) provided in the communication device sucks in from the front surface (intake side) and is used to cool the high temperature durable information communication device and then exhausts to the back surface (exhaust side). The exhaust at this time has a high temperature of 35 ° C. to 50 ° C., for example. Accordingly, the space on the back side of the high temperature durable device rows HL1 and HL2 forms a super hot aisle SH that is higher in temperature than the hot aisle H.

  The air of super hot aisle SH, hot aisle H, and cold aisle C should not be mixed. Therefore, in this air conditioning system 1, in order to avoid air contamination of cold aisle C, hot aisle H, super hot aisle SH, An appropriate partition is provided between the rear side end portions (peripheral portions) of the standard equipment rows SL1 and SL2 and the front side end portions (peripheral portions) of the high temperature durable equipment rows HL1 and HL2 and the ceiling, the vicinity of the ceiling, and the floor surface. It is preferable to install the materials 4, 5, 6, 7, and 8 so as to enhance the airtightness and independence of each space. It is preferable to use a heat-insulating material for this kind of partition material, and it is preferable to appropriately select a panel-like material or a sheet-like material depending on the part.

  The hot air of the super hot aisle SH is introduced into the air conditioners 2 and 3 of the air conditioning machine room M as the return air RA1. As the introduction route to the air conditioners 2 and 3, a known technique applied to this kind of so-called server room can be applied. For example, the route from the return vent formed on the floor to the space below the floor, the route from the return vent formed on the ceiling to the space behind the ceiling, the route from the return vent formed on the wall of the room R, etc. And ducts may be used as needed. This also applies to the embodiments described later.

  Further, a part of the air of the hot aisle H may be directly introduced from the hot aisle H to the air return ports of the air conditioners 2 and 3 in the air conditioning machine room M as the return air RA2. The temperature of the return air RA2 from the hot aisle H is lower than the temperature of the return air RA1 from the super hot aisle SH. In addition, a known technique of this kind can be adopted for the introduction route of the return air RA2 to the air conditioners 2 and 3 as well as the return air RA2.

  The above-described bypass portions 30, 31, 40, 41 may be configured as, for example, bypass openings formed in the partition members 5, 6, and in that case, an opening variable shutter for flow rate adjustment is provided in the bypass openings. And a backflow prevention mechanism is provided.

  According to the air conditioning system according to the above configuration, the air in the cold aisle C is used for cooling the standard information communication equipment mounted on the racks 10 of the standard equipment rows SL1 and SL2, and then the temperature is raised to hot aisle H. Exhausted. The hot aisle H air is used to cool the high temperature durable information communication devices mounted on the high temperature durable device rows HL1 and HL2. The high-temperature air thus used for cooling the high-temperature durable information communication device is further heated from the super hot aisle SH on the back side of the high-temperature durable device row HL1, HL2 as the return air RA1, the air conditioner 2, Return to 3

  Therefore, according to the air-conditioning system 1 according to the embodiment, both the standard information communication device whose operation is guaranteed in the standard temperature range and the high temperature durable information communication device whose operation is guaranteed even in the temperature range higher than the standard temperature range are accommodated. Even in the room R, the information communication devices can be efficiently cooled.

Moreover, in the air-conditioning equipment used in the conventional one-pass type air-conditioning system, it is operated at a temperature difference equivalent to the intake / exhaust temperature difference (10 to 15 ° C.) of the information communication equipment. On the other hand, in the air conditioning system 1 according to the embodiment, the temperature difference between the intake and exhaust of the information communication device is in two stages, that is, the standard information communication device and the high temperature durable information communication device. obtain. For example, if the intake / exhaust temperature difference of the standard information communication device (10-15 ° C.) is the same as the normal (10-15 ° C.), the air conditioning system 1 will eventually It is possible to ensure that the temperature difference between the intake and exhaust air of the air conditioners 2 and 3 is 20 to 30 ° C. For this reason, in order to process the heat generation load of the information communication device, the air supply amount of the air conditioner is reduced. That is, the amount of heat to be processed is calorie [kW] = air specific heat [kJ / (kg · K)] × air volume [m ³ / s] × air density (for example, 1.2) [kg / m ³ ] × temperature difference [K In the case of the same amount of heat, the air volume decreases if the temperature difference between the return air of the air conditioners 2 and 3 is increased. Therefore, as in the above example, when the hot air of the hot aisle H is once again used as the intake air for the high temperature durable information communication device, the temperature difference between the supply air and the return air of the air conditioners 2 and 3 is increased. The supply air volume can be reduced. In addition, since the temperature difference between the supply air and the return air is large, the efficiency of the air conditioner is improved, that is, the operation efficiency including the heat source side is improved, and the operation of the system is improved.

  In addition, since the air conditioner has a larger temperature difference as described above compared to the temperature difference of the return air of the conventional air conditioner, for example, the temperature span of the heat source equipment when the heat medium of the air conditioner is cold water also has a large temperature difference. It is expected that the temperature difference between the inlet and outlet of the refrigerator that generates the cold water can be greatly increased. Moreover, the standard information communication device and the high temperature durable information communication device were mounted in separate rack rows, and the exhausts were separated and used for cooling the standard information communication devices mounted in the standard device rows SL1 and SL2. Since the later high-temperature exhaust is used for cooling the high-temperature durable information communication device, the exhaust after use of the standard information communication device is effectively used. And since the exhaust after cooling a high temperature durable information-communication apparatus in that way becomes high temperature of 35 degreeC-50 degreeC, for example, the utility value of waste heat is increasing.

  Such high-temperature air can be used, for example, to improve the operation efficiency of the heat source of the air conditioner in the server room. For example, in a data center where an absorption refrigerator is operated with steam made from boiler or factory waste heat, etc., the boiler water is preheated with the heat of high-temperature air to assist steam production. As a result, it can assist cooling. Of course, as other applications other than the cooling of the communication information equipment described above, for example, used as a heat source for air conditioning in other places and rooms, that is, for manufacturing hot water or assisting it, for heating, other than data center It can also be used to improve the efficiency of the heat source for air conditioning.

  In the example shown in FIG. 2, in order to use the exhaust heat of the high-temperature return air RA1 from the super hot aisle SH, the waste heat is used during the introduction route of the return air RA1 to the air conditioners 2 and 3. Equipment, for example, heat exchangers 51 and 52 are provided. For example, the heat exchangers 51 and 52 are guided with a heat medium that circulates between the heat demand devices of different systems. Thus, as described above, the waste heat can be effectively used and the temperature of the return air RA1 introduced into the air conditioners 2 and 3 can be lowered, thereby reducing the load on the air conditioners 2 and 3. Is possible. If the temperature of the return air RA1 is lowered to a temperature similar to that of the hot aisle H, for example, about 30 ° C. by the heat exchangers 51 and 52, a part or all of the return air RA1 is hot without being introduced into the air conditioners 2 and 3. You may make it return to Isle H. The heat exchangers 51 and 52 are not devices that generate waste heat, and a cooling tower may be connected via a pipe.

  By the way, as described above, an information communication device has a server fan for cooling inside, and is usually configured such that the rotation speed of the fan is controlled according to the amount of heat generated by the operation of the information communication device. . Accordingly, the air volume for each rack row varies depending on the operating status of the information communication equipment. For example, the air flow rate of the entire fan included in the standard information communication device mounted in the standard device rows SL1 and SL2 is larger than the air flow rate of the entire fan included in the high temperature durable information communication device mounted in the high temperature durable device row HL1 and HL2. If it is larger, an excessive air volume is supplied to the high-temperature durable device rows HL1, HL2, which causes a problem that the back pressure of the server fan increases and the server fan fails.

  Conversely, the air flow of the entire fan included in the standard information communication device mounted in the standard device rows SL1 and SL2 is the same as the air flow of the entire fan included in the high temperature durable information communication device mounted in the high temperature durable device row HL1 and HL2. If it is smaller than that, the air flow for the high-temperature durable device rows HL1 and HL2 will be insufficient, causing a failure due to overheating of the high-temperature durable information communication device, a shutdown for self-protection, and a back flow of hot exhaust gas in the high-temperature durable information communication device. This causes problems such as high-temperature tolerant information and communication equipment itself running out of control.

  In this regard, in the air conditioning system 1 according to the embodiment, since the bypass units 30 and 31 are provided, the airflow does not pass between the cold aisle C and the hot aisle H without passing through the standard equipment rows SL1 and SL2. Can be passed around. Moreover, since the bypass parts 40 and 41 are provided, it is possible for the airflow to pass between the hot aisle H and the super hot aisle SH without passing through the high-temperature durable device rows HL1 and HL2. Therefore, it is possible to prevent failure of the server fan, failure due to overheating caused by insufficient airflow, shutdown, and thermal runaway due to the airflow fluctuation for each rack row due to the operation status of the information communication apparatus as described above.

  For the bypass units 30, 31, 40, 41, for example, a damper, an MD (motor damper), a VD (air volume adjustment damper), a balance damper, or a differential pressure damper is used as a device (flow rate adjustment mechanism) for adjusting the bypass air volume. Can do. As for the control method, for example, when the opening degree of the bypass damper is adjusted according to the differential pressure between the spaces of the cold aisle C, the hot aisle H, and the super hot aisle SH, or when automatic control is not used, If a differential pressure is applied, the amount of bypass can be adjusted by installing a check damper that opens according to the differential pressure direction. In addition, it is also possible to measure the intake air temperature of the rack and close the bypass damper to increase the air volume of the air conditioner when the temperature exceeds a predetermined temperature so that the cool air can flow through the rack. It is also possible to measure the power used in each rack and control the bypass damper opening according to the magnitude of the power.

  Note that the air volume of the entire fan included in the standard information communication device mounted in the standard device rows SL1 and SL2 is larger than the air flow of the entire fan included in the high temperature durable information communication device mounted in the high temperature durable device row HL1 and HL2. In some cases, part of the air in the hot aisle H may be returned directly to the air conditioners 2 and 3.

  The position where the bypass portion is provided is not particularly limited, but in order to prevent (reduce) the high temperature air of the super hot aisle SH from flowing back to the cold aisle C, the bypass portions 30 and 31 on the cold aisle C side and the super hot aisle It is desirable that the SH side bypass units 40 and 41 be provided apart from each other.

  In the air conditioning system 1 shown in FIGS. 1 and 2, the standard equipment rows SL1 and SL2 and the high temperature durable equipment rows HL1 and HL2 are not arranged in a cascade in terms of layout, but are arranged in the same row. In an existing server room, etc., when replacing a rack row equipped with some standard information communication equipment with a rack row equipped with high temperature durable information communication equipment, the orientation of the high temperature durable information communication equipment is opposite to that of the standard information communications equipment. Therefore, when these information communication equipment columns coexist, the layout change can be minimized.

  In the air conditioning system 61 shown in FIG. 3, the high temperature durable device rows HL1 and HL2 are arranged opposite to the room R and another room RS, and the air conditioners 2 and 3 are arranged in the same row as the standard device rows SL1 and SL2, respectively. Shows the layout. That is, the hot aisle H formed in the exhaust side space of the standard equipment rows SL1 and SL2 is used as the intake side space of the high temperature durable equipment rows HL1 and HL2 and the inlet (introduction) side space of the air conditioners 2 and 3. The air conditioners 2 and 3 are provided with a return port on the back and an air supply port on the front, and the air supply port is directed to the cold aisle C so that the air supply direction is opposite to that of the standard equipment rows SL1 and SL2. The high-temperature return air RA1 from the high-temperature durable device rows HL1 and HL2 is lowered through the heat exchangers 51 and 52 for use of waste heat and then introduced into the hot aisle H. The space area between the room R and the room RS may be used as a passage, and the partition members 5 and 6 may be used as maintenance entrances. In addition, the room R and the room RS are not separated from each other, but are separated from each other by a heat insulating wall having improved heat insulating properties, such as a heat insulating material, without providing a space between the two areas. May be.

  According to the air conditioning system 61, the supply air from the air conditioners 2 and 3 is supplied to the intake side space of the standard equipment rows SL1 and SL2, and the cold aisle C is formed in the intake side space. The air of the cold aisle C is sucked by a small fan of a standard information communication device mounted on the rack 10 of the standard device row SL1, SL2, and is used to cool the standard information communication device, and then the temperature is raised. The hot aisle H on the side is exhausted. The air in the hot aisle H is used for cooling the high temperature durable information communication devices in the high temperature durable device rows HL1 and HL2 configured by the rack 20 equipped with the high temperature durable information communication devices arranged with the hot aisle H as the intake side. used. As a result, the hot air whose temperature is further increased is exhausted to the super hot aisle SH. The air of the super hot aisle SH is lowered by the heat exchangers 51 and 52 while being returned to the hot aisle H as the return air RA1, and then returned to the hot aisle H.

  The air conditioning system 61 is useful when there is no room to provide the air conditioning machine room M, can improve the rack installable space ratio (rentable ratio) in the room R, and can be a merit for the data center operator. Since the high temperature durable equipment rows HL1 and HL2 and the super hot aisle SH are set in a room RS different from the room R, the temperature barrier property due to the separation between the cold aisle C and the super hot aisle SH is good.

In the air conditioning system 71 shown in FIG. 4, the high temperature durable equipment rows HL1 and HL2 are arranged opposite to each other with the hot aisle H on the same side as the standard equipment rows SL1 and SL2 in the room R and on the air conditioning machine room M side. Super hot aisle SH is set in the space on the back side of the high temperature durable equipment rows HL1, HL2 and partitioned by the partition members 72, 73, the rack 10 of the standard equipment rows SL1, SL2, and the air conditioning machine room M It is.
Note that the super hot aisle SH is formed small on the back side of the high-temperature-resistant equipment and is partitioned so that high-temperature exhaust flows in the upper space of the region on the back side of the rack 20. The partition area of the upper space on the side is also represented as super hot aisle SH. By doing in this way, the area of the cold aisle C can be ensured widely. The return air RA1 from the super hot aisle SH is configured to be introduced into the air conditioning machine room M in which the air conditioners 2 and 3 are installed. The return air RA2 from the hot aisle H is also introduced into the air conditioning machine room M. Note that the bypass portions 40 and 41 of the super hot aisle SH may be set at one end of the high temperature durable device rows HL1 and HL2, if necessary.
