Description

  The present invention relates to a rack in which rack-mounted computers are stored side by side in a height direction, an air conditioning system for cooling the rack-mounted computer stored in the rack, and an air conditioning method.

  As computer equipment has become more open, computer equipment has become smaller and the tendency to mount computer equipment in a rack at a high density has increased. It has increased. In addition, with the opening of computer equipment, computer equipment vendors and rack vendors are rarely involved in computer room building design and air conditioner design, and after computer room building design is complete, There are increasing examples of recognizing thermal problems since the start of operation of computer equipment installed in computer rooms.

  In order to cool computer equipment mounted on a rack with a height of about 2m from the experience of dealing with the heat problem of such a computer room, the design of the conventional air conditioner in the computer room, that is, the amount of heat generated, Appropriate cooling efficiency could not be obtained by the method of selecting an air conditioner based on the calculation result of air flow and setting the device layout. Even if the cooling capacity and required air volume of the air conditioner are set sufficiently, the path between the cooling airflow supplied by the air conditioner and the exhaust heat stream discharged from the computer equipment is not properly formed. The cooling efficiency was deteriorated.

  However, even if these causes are found, it is difficult to make drastic improvements after the computer room architectural design and construction work is completed. There are many examples to deal with by doing. The conventional measures of adding air conditioning equipment and investing in equipment and power to improve cooling efficiency are burdensome for companies seeking to reduce costs and require a reduction in environmental impact. Considering the global situation, it may be a factor that lowers the market value of corporate value.

Therefore, it is necessary to drastically review the conventional design method and construction method for the temperature control by the air conditioner in the computer room. The overwhelming majority of conventional computer room construction is the installation of computer equipment and replacement of computer equipment in existing computer rooms, and it is necessary to solve the thermal problems that occur at that time.

  As described above, problems in the computer room air conditioning system related to the present invention will be described with reference to FIGS.

  Along with the transition of the computer equipment from the mainframe computer equipment 100 to the rack-mounted computer equipment 101, the conventional computer room air-conditioning method deteriorates the air flow distribution and causes a heat problem that causes a heat pool (hot spot). Has occurred. There are mainly three causes for the deterioration of the airflow distribution in the computer room.

  The first cause is that the computer equipment is changed from an underfloor air-conditioning mainframe computer equipment 100 as shown in FIGS. 9 and 10 to an atmospheric air-conditioning rack-mounted computer equipment 101 as shown in FIGS. Due to the transition to The computer room underfloor blowout package type air conditioner 105 (hereinafter referred to as an air conditioner) used in the computer room sucks the equipment exhaust heat airflow A1 exhausted from the computer equipment from above, and heat exchanger 105a. Heat is exchanged by evaporation in the air, and the cooling airflow A2 is supplied to the air conditioning duct space 107 below the floor between the double floor 106a and the foundation floor 106b by the blower fan 105b. This is because the consistency of the airflow between the air conditioner 105 and the rack-mounted computer device 101 is deteriorated, and it is difficult to make the temperature distribution in the computer room uniform.

  More specifically, in the conventional mainframe type computer apparatus 100, the design exclusively for the housing is independently performed, and the floor cut 106a provided on the floor 106 on which the housing 100a is installed is provided. The air-conditioning cooling airflow A2 is sucked into the housing 100a from the bottom surface air inlet 100b provided on the bottom surface of the housing 100a, and the cooling airflow A2 is sent upward through the apparatus main body 100e by the blower fan 100d. The structure which discharge | releases apparatus waste heat airflow A1 of the mainframe type computer apparatus 100 from the top | upper surface exhaust port 100c of this was taken. For this reason, the airflow in the conventional mainframe type computer apparatus 100 is sufficiently aligned with the direction of the airflow by the air conditioner 105, and the mainframe type computer apparatus 100 can be efficiently cooled.

  On the other hand, as shown in FIGS. 11 and 12, the recent rack-mounted computer equipment 101 has a structure mounted on a rack 111 having versatility. The cooling structure has been changed to take the cooling airflow from the vent hole of the door 112a and exhaust the equipment exhaust heat airflow A1 from the vent hole of the rear door 112b with the exhaust hole of the rack 111 or the rack blower fan 112d disposed in the vicinity of the upper surface 112c. .

  The cooling airflow A2 supplied from the air conditioner 105 passes through the underfloor air-conditioning duct space 107 between the double floor 106a and the foundation floor 106b, and is provided with a floor panel 106c (so-called gallery, gallery, grill, louver) with a vent hole. Through a vent hole of a perforated floor panel, etc.) and blown up on the floor. However, in the air conditioner, since sufficient wind power that allows the cooling airflow to reach the top of the rack 111 having a height of about 2 m cannot be obtained, the computer equipment mounted from the middle to the top in the height direction of the rack 111. It is difficult to cool 101 efficiently. Therefore, depending on the conditions such as the location of the rack and the height of the rack, the air conditioning conditions by the air conditioner, the ceiling height of the computer room, and the building conditions such as the height of the air conditioning duct space under the floor, the temperature difference inside the rack Will occur.

  The second cause is that the air flow rate by the air conditioner 105 is large, so that the cooling airflow A3 blown up from the floor panel with the vent holes is blown up to the upper front of the rack 111 and reaches the air conditioner 105. This is because a so-called short return airflow A4 is generated in which the cooling airflow A3 returns to the air conditioner 105 without being sufficiently used for cooling. For this reason, although the lower part of the rack 111 is cooled, the cooling airflow A2 is not supplied from the middle stage to the upper stage in the height direction of the rack 111, so that the temperature difference in the height direction inside the rack 111 is large. In addition, since the cooling efficiency by the air conditioner 105 is deteriorated, wasteful power consumption by the air conditioner 105 is caused.

  The third cause is that the rack-mounted computer equipment 101 is downsized year by year, and the user uses the rack 111 having a higher height for the purpose of space saving. This is because there is a tendency to install. For this reason, the mounting density of the rack-mounted computer device 101 in the rack 111 and the heat generation density in the computer room are overcrowded, and the temperature distribution in the computer room is not uniformized.

  Further, as the mounting density of the rack-mounted computer equipment 101 in the rack 111 is increased, the required amount of cooling air flow increases, so that the cooling air flow from the middle stage to the upper stage of the rack 111 by the air conditioning device 105 is increased. A2 is not sufficiently supplied, and exhaust heat from the rack-mounted computer device 101 stays on the back surface and the top surface of the rack 111. Then, the staying device exhaust heat flows toward the front surface of the rack 111 through the path above the rack 111, and the rack-mounted computer device 101 sucks the exhaust heat flow again. Exhaust heat reflux A5 is generated. As a result, a temperature difference occurs in the height direction of the rack 111 according to the height of the rack 111.

  Therefore, in order to improve the airflow by the air conditioner, it is necessary to review the fundamental architectural structure and air conditioning structure from the design stage. However, the computer equipment operation manager recognizes the thermal problem as described above only after installing the computer equipment in the computer room and starting the operation. Therefore, it is very difficult to make a radical architectural design change of the computer room after the operation of the computer equipment is started. For this reason, there is a demand for more effective measures for airflow improvement without changing the design of the building structure or air conditioning structure.

  As a measure for improving the temperature distribution in the computer room, setting the temperature of the cooling airflow A2 by the air conditioner 105 to be lower is considered as the simplest method. However, even when the temperature of the cooling airflow A2 supplied by the air conditioner 105 is lowered, the cooling airflow A2 is not sufficiently blown up to the upper portion of the rack 111. For this reason, in this method, the temperature of the upper part of the rack 111 is not changed, and the temperature of the lower part of the rack 111 is lowered. This results in increasing the temperature difference between the upper part and the lower part of the rack 111.

  As another countermeasure, there is a method of increasing the amount of air supplied to the atmosphere by rotating the blower fan of the air conditioner 105 at a high speed or expanding the opening area of the vent hole of the floor panel 106c with the vent hole. It is done. However, even when such measures are taken, sufficient wind power to blow up to the top of the rack 111 cannot be obtained. As a result, the temperature distribution between the upper and lower portions of the rack 111 is increased.

  Therefore, measures that have been considered to be the most effective in the past have been to install a blower around the rack to improve the airflow, place a rack-mounted air conditioner inside the rack, This is a method of adding a new cooling device, such as adding an air conditioning device to the vehicle. However, when adding an air conditioner, the location where the air conditioner can be installed and the power are limited, so it may not be possible to install the air conditioner. Since measures are only taken, it is difficult to improve the entire computer room.

  Further, as in the conventional measures described above, in the method of setting the temperature of the air conditioner low to suppress the temperature rise or additionally installing the air conditioner, the capital investment of the computer equipment operation manager or Electricity burden increases, and it is against the reduction of energy consumption, resulting in a lack of consideration for the global environment.

  In other words, the above-described conventional method has poor cooling efficiency for cooling the rack-mounted computer equipment mounted on the rack, and requires air-conditioning power that is higher than the power used by the rack-mounted computer equipment. However, this is a problem in cooling rack-mounted computer equipment.

  Therefore, the present invention solves the above-described problems, and enables the airflow adjustment member to block the airflow drawn into the air conditioner from the middle of the rack height direction, thereby improving the cooling efficiency of the rack-mounted computer equipment. It is an object to provide a rack, an air conditioning system, and an air conditioning method that can be performed.

  In order to achieve the above-described object, the rack according to the present invention includes a plurality of rack-mounted computer devices arranged side by side in the height direction, and is supplied with a cooling airflow from below the floor through the inside through the air conditioner. The airflow adjustment member for controlling the airflow by an air conditioner by covering the space between the racks and other racks arranged at intervals is provided.

In addition, an air conditioning system according to the present invention includes a plurality of racks in which a plurality of rack-mounted computer devices are stored side by side in the height direction,
A cooling airflow that flows from the bottom of the room where multiple racks are placed to the upper side of the rack through the interior of the rack is supplied, and the exhausted airflow that has escaped from the rack to the ceiling is circulated and stored in the rack. An air conditioner for cooling rack-mounted computer equipment
And an air conditioning system in which a first rack row and a second rack row in which a plurality of racks are arranged are arranged with a space therebetween, wherein the first and second rack rows Each rack is provided with an airflow adjusting member for covering the space.

Further, the air conditioning method according to the present invention includes a first rack row and a second rack row in which a plurality of racks in which a plurality of rack-mounted computer devices are arranged and stored in the height direction are arranged,
A cooling airflow that flows from the bottom of the room where multiple racks are placed to the upper side of the rack through the interior of the rack is supplied, and the exhausted airflow that has escaped from the rack to the ceiling is circulated and stored in the rack.

Air is circulated by the air conditioner in a state where the space is covered by the airflow regulating members provided in the racks of the first rack row and the second rack row.

  According to the present invention, the rack is provided with an airflow adjustment member for controlling the airflow by the air conditioner so as to cover a space with other racks arranged at intervals, thereby discharging from the rack-mounted computer equipment. The cooling heat supplied from the air conditioner is controlled by suppressing the exhaust heat recirculation where the exhausted heat stream is drawn into the rack-mounted computer equipment and the short return airflow drawn into the air conditioner from the middle of the rack height direction. This makes it possible to efficiently supply the airflow in the height direction inside the rack, and to efficiently cool the rack-mounted computer equipment.

The side door panel 20 is made of a light-transmitting material, and can transmit illumination light in the computer room.

  As shown in FIG. 7, a plurality of rack-mounted computer devices 1 are mounted in the racks 11a and 11b, respectively. The rack-mounted computer device 1 draws the air-conditioning cooling airflow A2 from the vent hole of the front door 12a with the air intake hole of the rack 11, and releases the exhaust heat airflow toward the rear surface 12b of the rack 11 by the device blower fan 1a. To do.

  A predetermined number of rack blower fans 12d are attached to the top plate 12c of the racks 11a and 11b in order to discharge the exhaust heat stream from the rack-mounted computer device 1 to the top surface of the rack 11.

  As shown in FIG. 1, the plurality of racks 11 (11 a, 11 b) are arranged with their front surfaces facing the air conditioner 5 side adjacent to each other. A desired number of racks 11 are installed according to the capacity of the computer room and the cooling performance of the air conditioner 5. In the configuration example shown in FIGS. 1 to 8, an example is shown in which rack rows 13 and 14 including five racks 11 are arranged in two rows facing each other with a space therebetween. Each rack 11 of the first rack row 13 and each rack 11 of the second rack row 14 are arranged with the front door 12a side facing each other.

  The ceiling panel 15 of the rack 11 is moved to the front door 12a side of the rack 11 along the ceiling slide rail 17, and the ceiling frames 16 of the racks 11 facing each other are brought into contact with each other to be engaged. It is fixed to the rail 17.

  When a plurality of racks 11 are installed, the side door panel 20 provided on the side surface of one side of the rack 11b disposed at both ends of the rack rows 13 and 14 is arranged along the side door slide rail 22 with the rack 11b. The side door frames 21 of the other racks 11 b facing each other are brought into contact with each other and engaged with each other, and the side door frames 21 are fixed to the side door slide rails 22. Further, when a person goes in and out of the space between the first rack row 13 and the second rack row 14, the side door panel 20 is moved along the side door slide rail 22 toward the back surface 12 b of the rack 11 b. Now you can enter.

  Regarding the air conditioning system configured as described above, the operation of the air conditioning device 5 for circulating the air in the computer room will be described with reference to FIGS. 1, 2, 7 and 8.

  The cooling airflow A3 supplied from the air conditioner 5 is supplied to the entire computer room through the air conditioning duct space 107 below the double floor 6a. The airflow-controlled cooling airflow A3 passes through the ventilation holes of the floor panel 6c with ventilation holes installed on the double floor 6a on the front door 12a side of the rack 11, and the cooling airflow A3 is placed on the floor of the rack 11 on the front door 12a side. Is supplied.

  In the conventional configuration, a part of the cooling airflow A2 that is supplied from above the floor of the double floor 106a to the floor through the ventilation hole of the floor panel 106b with ventilation holes is not supplied to the rack-mounted computer device 101. In addition, the short return airflow A4 that flows from the space on the front door 112a side of the rack 111 toward the air conditioner 105 side and is returned to the air conditioner 105 without being used for cooling is returned (recirculated). Will occur.

  On the other hand, according to the present embodiment, the cooling airflow that has not been supplied to the rack-mounted computer device 1 and has been drawn into the air conditioning device 5 is blocked by the side door panel 20, thereby reducing the supply amount of the cooling airflow A <b> 2. Almost all can be supplied to the rack 11.

  The rack-mounted computer equipment 1 takes in the cooling airflow A3 from the vent of the front door 12a of the rack 11, and the equipment exhaust heat airflow is generated by the equipment blower fan 1a of the rack-mounted computer equipment 1 and the rack blower fan 12d of the rack 11. Is exhausted toward the rear surface 12b side and the upper part of the rack 11. In the conventional configuration, a part of the air flow thus exhausted passes through the space between the ceiling of the computer room and the top plate of the rack 11 and wraps around the front door 12a side of the rack 11 to mount the rack. The type computer 1 forms an undesired exhaust heat stream circulation path that sucks in its own exhaust heat stream.

  On the other hand, according to the present embodiment, the ceiling panel 15 provided in the rack 11 can also block the exhaust heat flow that flows above the rack 11 and circulates to the front door 12a side, and the floor panel 6c with a vent hole is provided. It is possible to efficiently supply the cooling airflow A3 that is blown up on the floor through the ventilation holes of the rack 11 from the lower part to the upper part of the rack 11 in the whole height direction.

  Further, at the upper part of the side door panel 20, when the air conditioner 5 stops, the rack 11 has a front door 12 a side of the first rack row 13 and a front door 12 a side of the second rack row 14. A side panel 23 with vents is provided for supplying air to the space therebetween.

  As described above, according to the air conditioning system of the present embodiment, each rack 11 of the first rack row 13 and the second rack row 14 includes the first rack row 13 and the second rack row 14. A ceiling panel 15 and a side door panel 20 are provided for covering the space between them. With this configuration, the exhaust heat flow released from the rank 11 is prevented from being drawn into the computer equipment 1 from the front door 12a side of the rack 11 through the top of the rack 11 and air from the middle of the rack 11 in the height direction. The cooling air flow drawn into the adjusting device 5 can be shut off. That is, according to the present embodiment, the following effects can be obtained.

  The first effect is that a cooling airflow having a uniform temperature can be supplied in the height direction from the lower part to the upper part of the rack 11. The reason is that the exhaust heat flow of the rack-mounted computer device 1 can be suppressed around the rack 11 and the temperature distribution in the height direction from the lower part to the upper part of the rack 11 can be reduced.

  As a second effect, the reach distance of the cooling air flow by the air conditioning device is extended, and the computer room can be uniformly cooled. The reason for this is that a part of the cooling airflow A3 blown up from the floor panel with a vent hole has been used in the past, and is not used to cool the computer equipment, but is directly recirculated to the air conditioner. . However, according to the present embodiment, almost the entire supply amount of the cooling airflow can be supplied to the computer equipment 1 in the rack 11, so that the wasteful recirculation of the cooling airflow is suppressed and the reach of the cooling airflow is increased. Because it can.

  As a third effect, the set temperature of the air conditioner can be set higher than before, and the operation can be performed while suppressing the energy consumption of the air conditioner. The reason is that the cooling airflow supplied from the air conditioner can be supplied so that the temperature from the lower part to the upper part of the rack is constant, so that it is necessary to extremely lower the temperature under the floor as in a conventional computer room. This is because it disappears. For example, in a conventional computer room, the temperature of the cooling airflow supplied to the rack is set to about 20 ° C. to 28 ° C. by setting the air supply temperature of the air conditioner to about 18 ° C. On the other hand, in this embodiment, by setting the temperature of the cooling airflow supplied by the air conditioner to about 23 ° C., the temperature of the cooling airflow supplied to the rack is 23 ° C. to the operating temperature recommended for computer equipment. It becomes possible to set to a constant temperature of about 25 ° C. That is, in this example, since the set temperature of the air conditioner can be set higher by about 5 ° C., the power consumption by the air conditioner can be suppressed. Furthermore, according to the present invention, the operating temperature of the computer device 1 can be kept low, and the computer device 1 can be used stably.

  As a fourth effect, it is possible to reduce the number of installed air conditioners in the computer room, and it is possible to suppress excessive capital investment and power costs. The reason is that the warm air in the computer room is efficiently ventilated by the air conditioner, so that the cooling efficiency by the air conditioner is improved. As a result, it is possible to sufficiently cool by a minimum number of air conditioners, and in order to cool the entire computer room as in the past, an air conditioner that is more than the heat load in the computer room is installed. This is because it is not necessary. Conventionally, as a measure to make up for the shortage of air volume in the computer room, it has been necessary to add supply power along with measures such as increasing the number of air conditioning devices or installing a separate blower fan. According to the above, by adopting a simple configuration in which the rack 11 is provided with the ceiling panel 15 and the side door panel 20, no additional supply power is required, energy consumption is reduced, and optimal cooling and exhaust heat treatment are performed. Can also take into account the global environment.
