In the server room 1, a plurality of server racks 2 are arranged, and a plurality of air conditioners 3 for performing air conditioning in the server room 1 are provided. In the server rack 2, a server is accommodated as an information technology (IT) device.

The inside of the server room 1 is supplied with cool air by a plurality of air conditioners 3 in order to eliminate an area that is excessively cooled (an area where excessively cool air is supplied) or a hot spot area. In the server room 1, as the temperature control in the server room 1, an air supply temperature constant control for constantly controlling the temperature (air supply temperature) of air blown from the air conditioner 3, A constant intake temperature control is performed to control the temperature of the air (intake temperature) constantly (see, for example, Patent Document 1).

[Principle of the invention]

First, the principle of the present invention will be described. As a principle of the present invention, the intake temperature (one point for one rack) of the server rack is measured for a server rack installed in the server room. The air conditioning zone is specified and defined by determining the response of the intake temperature of the server rack by lowering the set value of the air supply temperature of only one air conditioner for a certain period of time.

Fig. 5 shows the images of the air conditioning zones served by the air conditioners 3-1 to 3-6 as Z1 to Z6. The density of the openings (grill panels) of the floor changes depending on the load density of the IT devices because the amount of cool air required by the server rack 2 differs depending on the density of the IT devices mounted on the server rack 2. As a result, the size of the air conditioning zone Z occupied by one air conditioner 3 fluctuates.

One of the reasons that it is difficult to understand the air conditioning zone is the complexity of the air flow. That is, complicated processes such as airflow analysis are indispensable and are generally recognized. On the contrary, the present inventors paid attention to the relationship between the air flow and the temperature of the server room. Since the server room has a high heat density, it requires a very large amount of air for cooling. Therefore, there is a strong correlation between the rack temperature and the air supply temperature of the air conditioner. Therefore, when the temperature difference is changed by changing the supply air temperature of the air conditioner, heat exchange between the air conditioning zones due to the turbulence of the airflow or the temperature difference is less likely to occur compared with the normal air conditioning zone. By clarifying the above-described characteristics, the air conditioning zone is grasped by using the operation of the supply air temperature or the temperature change of the trend.

[Embodiment Mode]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Fig. 1 is a view showing the main part of an air conditioning system 100 including an air conditioning zone discriminating apparatus in a server room according to an embodiment of the present invention. In Fig. 1, the same reference numerals as those in Fig. 5 denote the same or equivalent components as those described with reference to Fig. 5, and a description thereof will be omitted.

In order to simplify the explanation in Fig. 1, three air conditioners 3-1 to 3-3 are provided for sharing the air conditioner in the server room 1, and the air conditioners 3-1 to 3-3 And the air conditioning zones (Z) in charge are Z1 to Z3. It is assumed that three server racks 2 are provided as one server rack group 4 and three server rack groups 4 are provided in the server room 1. [ Of the three server rack groups 4-1 to 4-3, the three server racks 2 constituting the server rack group 4-1 are the server racks 2-1 to 2-3, The three server racks 2 constituting the server rack group 4-2 are used as the server racks 2-4 to 2-6 and the three server racks 2 constituting the server rack group 4-3 are used Server racks 2-7 to 2-9.

In this embodiment, a rack temperature sensor S is provided in each server rack 2 for measuring the temperature of the air sucked into the server rack 2 as the rack temperature. That is, rack temperature sensors S1 to S9 are provided for the server racks 2-1 to 2-9. Each air conditioner 3 is provided with an air supply temperature sensor 5 for measuring the temperature of the air blown from the air conditioner 3 as the air supply temperature. That is, supply air temperature sensors 5-1 to 5-3 are provided for the air conditioners 3-1 to 3-3.

The air conditioning system 100 is provided with an air conditioning zone determination device 6 for determining an air conditioning zone Z occupied by each air conditioner 3 in the server room 1. [ This air conditioning zone determination device 6 corresponds to the air conditioning zone determination device in the server room according to the embodiment of the present invention. This air conditioning zone determination device 6 is realized by hardware consisting of a processor and a storage device, and a program for realizing various functions in cooperation with these hardware.

The air conditioning zone determination device 6 includes a rack temperature sensor attribute storage unit 61, a rack temperature variation observation unit 62, and a rack temperature sensor attribute determination unit 63. [ The relationship between the rack temperature sensor S and the temporarily determined air conditioning zone Z as a zone to which the rack temperature sensor S belongs is stored as an attribute of the rack temperature sensor in the rack temperature sensor attribute storage unit 61. [

The rack temperature change monitoring unit 62 determines one of the air conditioners 3-1 to 3-3 as the property judging object air conditioner 3 (3-N) It is checked whether or not the measured value of the supply air temperature to the server room 1 has changed. If there is no change, the set value of the supply air temperature is changed, and then the attribute determination target air conditioner 3-N A change in the rack temperature measured by the rack temperature sensor S temporarily determined as a sensor belonging to the air conditioning zone Z (ZN) is observed. The rack temperature change monitoring unit 62 not only has a function of observing changes in the rack temperature but also changes the setting values of the supply air temperature to the server room 1 from the air conditioners 3-1 to 3-3 Function.

The rack temperature sensor attribute determination unit 63 determines whether or not the rack temperature sensor S in which the change in the rack temperature is observed based on the change in the rack temperature observed by the rack temperature change observation unit 62 is detected by the attribute determination target air conditioner (3-N). If it is determined that the sensor belongs to the air conditioning zone (ZN) occupied by the property judging air conditioner (3-N), the sensor The temperature sensor S is determined as the rack temperature sensor belonging to the air conditioning zone ZN in which the property judging object air conditioner 3-N takes charge, and the temperature sensor S is set as the rack temperature sensor belonging to the air conditioning zone ZN The air conditioning zone ZN temporarily determined for the rack temperature sensor S is set to the air conditioning zone Z (ZN + 1) in which the next air conditioner 3 (3-N + 1) 1)).

The rack temperature change observer 62 also outputs the next air conditioner 3-N + 1 to the new property judging object air conditioner 3-N after the rack temperature sensor property judging unit 63 finishes the process , It is checked whether or not the measured value of the supply air temperature to the server room 1 from the new property determination target air conditioner 3-N has changed. If there is no change, the set value of the supply air temperature is changed A change in the rack temperature measured by the rack temperature sensor S temporarily determined as a sensor belonging to the air conditioning zone ZN occupied by the new property determination target air conditioner 3-N is observed. The rack temperature sensor attribute determination unit 63 repeats the above-described process until the air conditioning zone Z to which all the rack temperature sensors S belong is determined.

2 is a flowchart for explaining the processing performed in the air conditioning zone determination device 6 in more detail. First, the air conditioning zone Z to which each rack temperature sensor S belongs is determined temporarily (step S101). In this example, the zones to which the rack temperature sensors S1 to S3 belong are temporarily determined as the air conditioning zone Z1, the zones to which the rack temperature sensors S4 to S6 belong are temporarily determined as the air conditioning zone Z2, The zone to which the sensors S7 to S12 belong is temporarily decided as the air conditioning zone Z3. The relationship between the provisionally determined rack temperature sensor S and the air conditioning zone Z is stored in the rack temperature sensor attribute storage unit 61 as an attribute of the rack temperature sensor.

The provisional determination in step S101 may be performed by the air conditioning zone determination device 6 itself or by an operator. In addition, the temperature distribution (plan view) of the air-conditioning area may be created and displayed based on the measurement data from each rack temperature sensor S, or the air supply temperature of each of the air conditioners 3 and the measured rack temperature sensors S , And may temporarily determine the correlation between each rack temperature sensor S and each air conditioner 3. [0051]

Next, the air conditioning zone determining device 6 sets N = 1 (step S102), and sets the N = 1 st air conditioner 3-1 as the property judging object air conditioner. Then, the measurement value (supply air temperature measurement value) of the supply air temperature sensor 5-1 attached to the air conditioner 3-1 to be subjected to the property determination is acquired (step S103). The measured values (intake temperature) of the rack temperature sensors S1 to S3 temporarily determined as sensors belonging to the air conditioning zone Z1 of the air conditioner 3-1 to be subjected to the attribute determination are acquired (step S104) . Then, a deviation (temperature deviation) between the measurement values of the acquired rack temperature sensors S1 to S3 and the air supply temperature measurement value of the attribute judgment target air conditioner 3-1 is calculated (step S105).

Then, the air conditioning zone determining device 6 confirms whether there is a change in the supply air temperature measurement value of the property judging air conditioner 3-1 (step S106). Here, if there is a variation in the supply air temperature measurement value of the air conditioner 3-1 (YES in step S106), the process immediately proceeds to step S108. If there is no change in the air supply temperature measurement value of the air conditioner 3-1 to be subjected to the attribute determination (NO in step S106), the air supply temperature setting value of the air conditioner 3-1 to be subjected to attribute determination is lowered by a predetermined value / S107), and the process proceeds to step S108.

In step S108, the air conditioning zone determining device 6 acquires the supply air temperature measurement value of the air conditioner 3-1 as the attribute determination target, in the same manner as in step S103. In step S109, similarly to step S104, the measured values of the rack temperature sensors S1 to S3 temporarily determined as sensors belonging to the air conditioning zone Z1 occupied by the air conditioner 3-1 to be subjected to attribute determination (Suction temperature).

The air conditioning zone determining device 6 then calculates the deviation (temperature deviation) between the measurement values of the rack temperature sensors S1 to S3 and the air supply temperature measurement value of the property judging air conditioner 3-1 Step S110), it is checked whether there is a change in the temperature deviation obtained in Step S105 and the temperature deviation obtained in Step S110 (Step S111). The variation of the temperature deviation is identified for each calculated temperature variation. That is, the temperature deviation is checked for each of the rack temperature sensors S1 to S3. In addition, whether or not the temperature deviation fluctuates is determined as a predetermined threshold value.

Here, if there is no change in the temperature deviation (NO in step S111), the air conditioning zone determining device 6 sets the rack temperature sensor S to the air conditioning zone Z1 And the zone to which the rack temperature sensor S belongs is determined as the air conditioning zone Z1 in which the property judging object air conditioner 3-1 is responsible, (Step S112). On the other hand, when there is a variation in the temperature deviation (YES in step S111), the rack temperature sensor S is not a sensor belonging to the air conditioning zone Z1 occupied by the attribute judgment target air conditioner 3-1 (There is no correlation between the supply air temperature and the rack temperature), and the air conditioning zone Z1 temporarily determined as the zone to which the rack temperature sensor S belongs is determined as the air conditioning zone Z2) (step S113).

For example, when there is no variation in the temperature deviation of the rack temperature sensors S1 and S2 and there is a variation in the temperature deviation of the rack temperature sensor S3 in step S111, the zone where the rack temperature sensors S1 and S2 belong As the air conditioning zone Z1 occupied by the property judging air conditioner 3-1 and sets the air conditioner zone temporarily determined for the rack temperature sensor S3 as the air conditioning zone occupied by the next air conditioner 3-2 Z2) (see Fig. 3).

Then, the air conditioning zone determining device 6 confirms whether or not the air conditioning zone to which all the rack temperature sensors S belong is determined (step S114). In this case, since it is confirmed that N is not the last (N = 3) (NO in step S115), N = 0 is satisfied, since the air conditioning zone to which all the rack temperature sensors S belong is not yet determined (NO in step S114) N + 1 = 2 (step S116), and N = 2nd air conditioner 3-2 becomes the next property judging air conditioner, and the process returns to step S103.

As a result, the air conditioner to be subjected to the property determination is switched from the air conditioner 3-1 to the air conditioner 3-2, and the processes in and after step S103 are repeated. In this process, for example, when there is no variation in the temperature deviation of the rack temperature sensors S3, S4, S5 and the temperature deviation of the rack temperature sensor S6 varies, the rack temperature sensors S3, S4, Is determined as the air conditioning zone Z2 occupied by the air conditioner 3-2 for which the property is to be judged and the air conditioner zone temporarily determined for the rack temperature sensor S6 is determined by the next air conditioner 3-3 And is changed to the air conditioning zone Z3 (see Fig. 4).

In the same manner, the processes of steps S103 to S116 are repeated until the air conditioning zone to which all the rack temperature sensors S belong is determined in step S114. If it is confirmed that N is the last (N = 3) (YES in step S115), that is, even if all the rack temperature sensors S belong to the air conditioner 3-3 If the air conditioning zone is not confirmed, the process returns to step S102, and the process from step S103 onward is repeated with N = 1.

In the process performed by the air conditioning zone determining device 6, the rack temperature change monitoring unit 62 performs the processes of steps S102 to S110, and the rack temperature sensor attribute determination unit 63 performs the processes of steps S111 to S116 .

In this way, according to the air conditioning zone determination device 6 of the present embodiment, the rack temperature sensor S and the rack temperature sensor S belong to the air conditioner The relationship with the air conditioning zone Z will be determined and the air conditioning zone Z occupied by each air conditioner 3 can be grasped accurately and the temperature of the server rack 2 can be cooled more appropriately And the operation processing can be realized.

2, the measured value of the rack temperature sensor S temporarily determined as a sensor belonging to the air conditioning zone Z occupied by the property judging object air conditioner 3-N and the measured value of the rack temperature sensor S (Temperature deviation) from the measured value of the supply air temperature of the rack 3-N is observed as an index showing a change in the rack temperature measured by the rack temperature sensor S (when there is no variation in the temperature deviation, (There is a relationship between supply air temperature and rack temperature), there is no change in the rack temperature (regardless of the supply air temperature and the rack temperature) when there is a variation in the temperature deviation], and the variation in the observed temperature deviation It is determined whether or not the rack temperature sensor S whose temperature deviation is observed is a sensor belonging to the air conditioning zone Z carried by the attribute judgment target air conditioner 3. On the other hand, Belonging to the air conditioning zone (Z) It is also possible to observe only the change in the measured value of the rack temperature sensor S temporarily determined as the sensor and to make a determination based on the observed change in the measured value of the rack temperature sensor S.
