Description

  The present invention relates to an air conditioning facility, an air conditioning control device, a control method, a program, and a recording medium for controlling air conditioning in a computer room or the like.

  When an electronic device installed in a room such as a computer room starts operating, the temperature inside the device rises due to heat generation. In order to suppress this temperature rise, conventionally, an underfloor air conditioning system as shown in FIG. 12 has been adopted to suppress the temperature rise of the electronic device and the computer room. The underfloor air conditioning system mentioned above is provided with an air inlet for an electronic device installed on the free access floor through the floor gallery provided on the free access floor through which the cooling air sent from the air conditioner passes under the free access floor. It is configured to blow up to the front. In addition, the exhaust discharged from the electronic device is sent to the air conditioner through the exhaust duct.

  In the above-described underfloor air conditioning system, as shown in FIG. 13, there is no special air passage or the like under the free access floor of the computer room, the entire underfloor is filled with cooling air from the air conditioner, and the cooling air is The electronic device was cooled by blowing up from a louver provided on the inlet side of the electronic device. Therefore, in the underfloor air conditioning system described above, it is necessary to fill the cooling air even under the floor of the area where the electronic device is not installed, and it is necessary to cool the most among the electronic devices installed in the computer room. Since air conditioning must be performed according to the apparatus, there is a problem that an air conditioning facility having a cooling capacity / air blowing capacity larger than necessary is required.

  In order to solve the above problem, a technique for replacing an underfloor air-conditioning duct according to an increase or decrease of racks to be installed is disclosed (for example, Patent Document 1). In addition, a technique is also disclosed in which a dedicated intake-side fan is provided in the lower-floor duct portion on the intake port side of each electronic device in order to send the cooling air flowing through the under-floor intake duct to the electronic device (for example, Patent Document 2).

  Further, in relation to the above-described problem, in order to suppress the temperature rise in the image forming apparatus, a temperature sensor that transmits the temperature instead of the radio signal is provided in the vicinity of the module constituting the image forming apparatus. A technique for adjusting the amount of cooling air and adjusting the direction of wind based on a radio signal from a sensor is disclosed (for example, Patent Document 3).

  However, in the technique of Patent Document 1 described above, since the cooling air sent from the air conditioner cannot be dynamically switched, the cooling air cannot be intensively and efficiently blown to an electronic device that requires cooling. There was a problem.

  Further, the technique disclosed in Patent Document 2 has a problem in that restrictions on the layout of the apparatus become large because it is necessary to provide a dedicated fan in the duct portion of each electronic apparatus. Furthermore, since electric power is required to operate the fan and it is necessary to cool the heat generated by operating the fan, there has been a problem that more cooling air than necessary is required. Furthermore, in the technique of Patent Document 2, similarly to Patent Document 1, cooling air is blown to an electronic device that does not require cooling, and the cooling air is concentrated and efficiently applied to the electronic device that requires cooling. There was a problem that it was not possible to blow.

  On the other hand, the technique disclosed in Patent Document 3 is a technique for controlling the temperature inside the image forming apparatus housing. What is an underfloor air conditioning system that controls air conditioning from the mutual relationship between a computer room and an electronic device installed in the computer room? There is a big gap. For this reason, the technique of Patent Document 3 cannot be simply applied to an underfloor air conditioning system.

  The present invention has been made in view of such circumstances, and does not supply cooling air to the entire surface under the floor, but air conditioning equipment, air conditioning control apparatus, and control method for supplying cooling air to necessary portions in a concentrated manner.

The rack information setting unit 11 is rack information setting means for accepting setting inputs such as position information of a rack installed in a computer room or the like, information of an electronic device mounted on the rack, and the like. The rack information storage unit 12 is a rack information storage unit that stores information input from the rack information setting unit 11. The main information stored in the rack information storage unit 12 includes, for example, rack installation location information, mounting position information of electronic devices mounted in each rack (for example, the number of EIA (Electronic Industries Alliance)), each rack The recommended operating temperature range and the intake / exhaust temperature difference allowable value of the electronic device mounted on the.

The determination unit 14 is a determination unit that compares the information from the monitoring unit 10 with the information from the rack information storage unit 12 to determine the operation. The control unit 13 is a control unit that controls the air conditioning of the entire computer room based on the determination result of the determination unit 14 .

  The temperature measuring device 2 is a temperature measuring means, and for example, a temperature sensor can be applied. The temperature measurement device 2 communicates with the intake air temperature measurement unit 20 that measures the intake air temperature of the electronic device, the exhaust temperature measurement unit 21 that measures the exhaust temperature of the electronic device, and the air conditioning control device 1 and transmits and receives data. Part 22. The temperature measuring device 2 constantly monitors the intake air temperature and the exhaust gas temperature of the electronic device, and transmits the monitoring result to the monitoring unit 10 via the communication unit 22.

  In the unit shape panel 3, each partition plate is modularized, and the partition plate is an example of a wind direction adjusting unit 30 that can freely change the opening / closing angle based on an instruction from the control unit 13 of the air conditioning control device 1. It has. The unit shape panel 3 receives an instruction from the control unit 13 by communication means (not shown). Here, the free access floor, for example, as shown in FIG. 3, can use the space created between the panel and the original floor by placing the support leg on the original floor and fitting the panel on the support leg. It is a floor structure. In the free access floor shown in the example of FIG. 3, the height of the support legs is 350 mm to 450 mm, and the panel is a square having a side of 450 mm to 465 mm.

  The air conditioner 4 is a device that blows cooling air to prevent the temperature of the electronic device from rising. In addition, in FIG. 2, the air-conditioning equipment which concerns on this embodiment gave and demonstrated the example provided with the air-conditioning control apparatus 1, the temperature measurement apparatus 2, the unit shape panel 3, and the air conditioner 4. FIG. However, if the air conditioner 4 and the wind direction adjusting unit 30 shown in FIG. 1 are provided, the above-described effects of the present invention can be produced and the above-described problems can be solved.

  FIG. 4 shows a schematic configuration example of the air conditioning equipment according to the present embodiment. In the example shown in FIG. 4, five racks are installed on the free access floor. FIG. 4 shows a state in which cooling air intensively flows on the lower surface of the intake side floor of these racks, and only one of the racks is further blown from the operating state of the mounted electronic device. Is unnecessary, and the state where the blowing of cooling air is suppressed is shown as an example.

  In FIG. 4, the state of the partition plate under the free access floor is illustrated in a simplified manner, but the details include a louver as shown in FIG. 5. In addition, each louver can dynamically control its opening / closing angle based on an instruction from the control unit 13 of the air conditioning control device 1.

  FIG. 6 shows an operation outline example of the air conditioning equipment according to this embodiment. FIG. 7 shows an example of the flow of operations in the air conditioning equipment according to this embodiment. Below, the operation example of the air-conditioning equipment which concerns on this embodiment is demonstrated using the figure shown in FIG.6 and FIG.7.

  The air-conditioning equipment according to the present embodiment first has racks installed on the free access floor of the computer room, and when each rack is equipped with an electronic device, the position information of the installed racks and the racks are installed. The rack information setting unit 11 accepts input of information such as the mounting position information (for example, the number of EIAs) of the electronic device, the recommended operating temperature range of the electronic device mounted in each rack, the intake / exhaust temperature difference allowable value, and the like. Thus, the information as described above is registered in the rack information storage unit 12 as a database (DB: data base) (step S1). For racks installed in the computer room in advance, rack information and electronic device information are registered in the database in advance.

  Here, an example of information stored in the rack information storage unit 12 will be described. FIG. 8 shows an example of computer room location information. FIG. 9 is an example of rack installation location information in the case of the layout shown in FIG. In this example, the rack information storage unit 12 stores rack type, rack position information, mounted device information such as electronic devices mounted on the rack, electronic device mounting position information, and the like. The rack information storage unit 12 also stores information on each electronic device as shown in FIG. In FIG. 10, for example, the rack information storage unit 12 includes information on equipment that is an electronic device mounted on the rack, a lower limit value and an upper limit value of the recommended operating temperature of the electronic device, and an allowable value of a temperature difference between the intake air temperature and the exhaust gas temperature. Information such as the maximum intake / exhaust temperature difference is also stored.

  As described above, when new racks are installed, the first thing to do is to allow the cooling air to reach the place where each rack is installed and from the floor under the shortest path from the air outlet of the air conditioner 4 This is to control the partition plate of the unit-shaped panel 3 that is modularized, and the control by this series of operations is the basis of air conditioning control.

  That is, the air conditioning control device 1 controls the partition plates in each direction of the free access floor modularized for each unit shape panel 3 in the path from the air conditioner 4 to the cooling air inlet of the newly installed rack. Thus, the flow path is changed, and adjustment is performed so that the cooling air blows out from the floor glazing portion near the cooling air inlet. On the other hand, the louver opening / closing angle of each partition plate of the free access floor 3 in which the air conditioning control device 1 is modularized for each unit-shaped panel 3 for an area where no electronic device is installed and a rack that does not require cooling air To adjust the flow path so that the cooling air does not blow out from the inlet side louver. When a rack is further added to the computer room, the air-conditioning control device 1 optimizes the flow path again so that the cooling air can reach the inlet side floor gallery portion of the added rack. become.

  FIG. 5 shows an example in which the opening / closing angle of the louver modularized for each unit-shaped panel 3 is controlled. FIG. 5A shows an example of a louver controlled so as to allow cooling air to pass therethrough, and FIG. 5B shows an example of a louver controlled so as not to pass cooling air. Has been. As described above, the control unit 13 controls the angle of the louver, so that the flow path of the cooling air can be dynamically switched.

  5B shows an example in which the louver is closed so as not to pass the cooling air, but the louver is not completely closed, but the opening degree is adjusted so that a small amount of the cooling air is passed. Of course, it is possible. That is, since the air conditioning control device 1 can dynamically adjust the opening / closing angle of the louver to determine the opening degree, it is also possible to finely adjust the amount of cooling air supplied to the electronic device.

  FIG. 11 shows an example of the flow of louver control processing by the air conditioning control device 1 according to this embodiment. Here, an example of a method for dynamically switching the cooling air flow path will be described with reference to the flowchart shown in FIG. The case where N racks are installed in the direction in which the cooling air flows from the air conditioner 4 will be described as an example. The initial setting of the louver modularized for each unit-shaped panel 3 is the position direction in which the louver is closed. . For convenience of explanation, the direction of the cooling air from the air conditioner 4 is set so that it flows from the west side to the east side of the computer room. A cooling air flow path formed under the floor made of unit-shaped panels in which the racks 1 to N are installed is referred to as a cooling air flow path A. Then, a flow path formed under the floor formed by the unit-shaped panel on the south side of the row of cooling air flow paths A is referred to as a cooling air flow path B. Here, the cooling air passage A is provided with a louver for supplying cooling air to the rack on the floor, and the cooling air passage B is described as an example in which no louver is provided.

  As the air conditioning control operation, the air conditioning control device 1 starts louver control for the first rack (n = 1) (step S1101), but will be described below until the control for the Nth rack is completed. Repeat the operation. However, there are cases where N = 1.

  First, the control unit 13 determines whether or not the cooling air needs to be supplied to the rack n (step S1102). When it is determined that the cooling air needs to be supplied to the rack n (step S1102 / YES), the control unit 13 determines whether n = 1, that is, the rack n is the first rack (step S1103). ). When the rack n is the first rack, that is, the rack at the west end (step S1103 / YES), since the rack n is installed at a position closest to the air conditioner, the control unit 13 causes the rack n to be Control is performed to open the louver on the west side of the unit panel An, which is a unit shape panel in which is installed, and close the louver on the south side (step S1105). Then, the control unit 13 closes the louver on the west side of the unit panel Bn, which is the unit-shaped panel on the south side of the unit panel An (step S1106). Thereby, the cooling air from the air conditioner 4 can be supplied to the rack n at the shortest distance.

  On the other hand, when the rack n is not the first rack, that is, the rack at the west end in step S1103 (step S1103 / NO), the control unit 13 determines that the rack n-1 is a rack installed on one west side of the rack n. In step S1104, it is determined whether cooling air is necessary. When the control unit 13 determines that the cooling air is necessary for the rack n−1 (step S1104 / YES), the process proceeds to the processes of step S1105 and step S1106. That is, since the rack n-1 requires cooling air, the control unit 13 may control the cooling air to be blown from the rack n-1 to the rack n via the cooling air flow path A. It is not necessary to control to make a detour so that cooling air is not supplied to 1.

  When the control unit 13 determines in step S1104 that the cooling air is not required for the rack n-1 (step S1104 / NO), control is performed to open the louver on the west side of the unit panel Bn and close the louver on the south side. (Step S1107). Then, the control unit 13 performs control to close the west louver of the unit panel An and open the south louver (step S1108). As a result, the cooling air from the air conditioner 4 can be supplied to the rack n that requires cooling air, bypassing the rack n-1 that does not require cooling air.

  Next, it is determined whether or not the rack n to be processed is the Nth rack, that is, n = N (step S1117). When n = N and the rack n is determined to be the east end rack (step S1117 / YES), the control unit 13 closes the west louver of the unit panel An + 1 and the south louver of the unit shape panel Bn + 1. Close control is performed (step S1118), and the air conditioning control processing operation is terminated.

  On the other hand, if it is determined in step S1117 that rack n is not the east end rack (step S1117 / NO), n = n + 1 is set (step S1119), and the rack on the east side of rack n controlled by the above processing is set. In order to perform control, the process proceeds to step S1102.

  When it is determined in step S1102 that the cooling air is not necessary for the rack n (step S1102 / NO), the control unit 13 determines the louver on the west side and the south side of the unit shape panel An that is the unit shape panel in which the rack n is installed. The louver is closed (step S1109). Then, the control unit 13 determines whether n = 1, that is, the rack n is a west end rack (step S1110). When n = 1 (step S1110 / YES), since there is no rack on the west side of the rack n, the control unit 13 opens the louver on the west side of the unit shape panel An-1 (step S111). The south louver of An-1 is opened (step S1114), the west and south louvers of the unit shape panel Bn-1 are closed (step S1115), and then the west louver of the unit shape panel Bn is opened, and the south louver is opened. Close control is performed (step S1116). By controlling the louver by the control unit 13 in this way, it is possible to form a cooling air flow path that bypasses the rack n so as not to supply the cooling air. Next, the process proceeds to step S1117, and the same operation as that described above is performed.

  On the other hand, if the control unit 13 determines in step S1110 that the rack n is not the west end rack (step S1110 / NO), it is determined whether or not the cooling air is required for the rack n-1 (step S1112). When the control unit 13 determines that the cooling air is necessary for the rack n−1 (step S1112 / YES), the control unit 13 proceeds to the process of step S1114 and performs the same operation as the process described above. As described above, the control unit 13 controls the louver, thereby forming a cooling air flow path that does not supply cooling air to the rack n-1 and the rack n.

  When the control unit 13 determines in step S1112 that the cooling air is not required for the rack n-1 (step S1112 / NO), control is performed to close the louver on the west side of the unit shape panel An-1 (step S1113). . Then, the process proceeds to step S1116, and the same operation as that described above is performed. In this way, the control unit 13 controls the louver, thereby forming a cooling air flow path that supplies cooling air to the rack n-1 and does not supply cooling air to the rack n.

  By repeating the operation as described above, it becomes possible to suppress and control the flow of cooling air into the inlet side of the rack. The above operation is an example, and the present invention is not limited to this.

  Next, when the electronic device mounted in each rack starts operation, it is classified into those that need to lower the temperature of the electronic device and those that do not need to be, depending on the type and operating status of the electronic device. Think about different cases.

  First, the intake air temperature measurement unit 20 and the exhaust gas temperature measurement unit 21 of the temperature measurement device 2 attached to each rack or electronic device measure the intake air temperature and the exhaust gas temperature of each electronic device (step S2). And from the monitoring result of said step S2, the air-conditioning control apparatus 1 calculates the intake-exhaust temperature difference which is a difference of the intake temperature of each electronic device, and exhaust temperature (step S3).

  From the intake / exhaust temperature difference calculated in step S3 and the information registered in the rack information storage unit 12, the determination unit 14 of the air conditioning control device 1 determines whether or not the electronic device needs to be supplied with cooling air. (Step S4, Step S6). When the determination unit 14 determines that the electronic device is in an operating state that does not require cooling air, the control unit 13 controls the opening / closing angle of the air direction adjusting unit 30 to thereby control the rack inlet side galley of the electronic device. Adjust so that the cooling air does not reach the part. At this time, in the case where there is a rack on which an electronic device that requires cooling air continues to be installed at a position farther from the flow path of the cooling air that connects between the air conditioner 4 and the electronic device that does not require cooling air, Thus, a detour is created by the action of the control unit 13 and control is performed so as to continue supplying cooling air to an electronic device that requires cooling air.

  On the other hand, when the determination unit 14 determines that the cooling air needs to be supplied to the electronic device, the control unit 13 determines whether it is necessary to send the cooling air more than the current state. Then, the control unit 13 controls the opening / closing angle of the louver, which is a modular partition plate in the vicinity of the inlet side louver part of the rack on which the electronic device is mounted, so that the amount of cool air blown to the electronic device is reduced. adjust.

  If the determination unit 14 determines that it is not necessary to control the louver from the intake / exhaust temperature difference calculated in step S3 and the information stored in the rack information storage unit 12 (step S4 / NO, step S6 / NO), the control unit 13 does not control the louver.

  When all the electronic devices mounted on the rack installed in the computer room have stopped operating (step S8 / YES), the operation of the air conditioning equipment controlling the underfloor air conditioning is terminated. On the other hand, if all the electronic devices mounted on the rack installed in the computer room have not stopped operating (step S8 / NO), the air conditioning equipment performs air conditioning control by repeating the above-described processing.

  In the present embodiment, the air conditioner control unit needs cooling air for each electronic device based on the intake / exhaust temperature difference, which is the difference between the intake air temperature and the exhaust gas temperature of each electronic device measured by the temperature measurement device. Although the example of determining whether or not is described, it is needless to say that the present invention is not limited to this. For example, the temperature in each electronic device is directly measured by the temperature measuring device, and based on the measured temperature, the determination unit of the air conditioning control device determines whether or not each electronic device requires cooling air. It is also possible.

  According to the present embodiment, the opening / closing angle of each direction of the wind direction adjusting unit 30 modularized for each unit shape panel is dynamically controlled, so a rack is arranged instead of sending cooling air to the entire surface under the floor. It becomes possible to supply cooling air intensively to the lower part of the floor. Thereby, in a computer room or the like, it is not necessary to operate the air conditioning equipment with a higher cooling capacity than necessary, and energy saving operation with the operating capacity of the air conditioner lowered to the limit is possible.

  In addition, the air conditioning control device constantly monitors the racks that require cooling air and the racks that do not, among racks that are arranged in a computer room, etc. It is possible to control so that the cooling air is blown intensively from the portion. Therefore, regardless of the installation location (layout) of electronic devices that require cooling air and the room temperature distribution in the computer room, the air conditioner can blow the cooling air that is needed in the place where it is needed on a rack basis. In addition, the width of the computer room layout can be increased.

Further, in the embodiment described above, taking a louver example as cooling air adjustment means, by the air conditioning control device controls the opening angle of the louver, intensive from the intake port side louver portion of the rack which require cooling air In the above description, an example of controlling the cooling air to blow is described. However, the present invention is not limited to this. For example, a shutter or the like is adopted as the cooling air adjusting means , the shutter is modularized for each unit panel, and the air conditioning control means dynamically controls opening and closing of the shutter, thereby Functions and effects similar to those of the embodiment can be obtained.

  Here, similarly to the louver described above, even with the shutter, the degree of opening and closing of the cooling air can be adjusted, and it is of course possible to allow a small amount of cooling air to pass. That is, the air conditioning control device can dynamically adjust the degree of opening and closing of the shutter to determine the opening degree, so that it is possible to finely adjust the amount of cooling air supplied to the electronic device.

  Note that a program for a CPU (Central Processing Unit) to execute the processes shown in the flowcharts of the drawings constitutes a program according to the present invention. As a computer-readable recording medium for recording the program, a semiconductor storage unit, an optical and / or magnetic storage unit, or the like can be used. By using such a program and a recording medium in a system having a configuration different from that of each of the above-described embodiments and causing the CPU to execute the program, substantially the same effect as the present invention can be obtained.

  Although specifically described above based on the preferred embodiment, the present invention is not limited to the above-described air conditioning equipment, air conditioning control device, control method, program, and recording medium, and does not depart from the spirit of the invention. It goes without saying that various changes can be made.
