  The indoor air conditioner 5 generates cooling air supplied to each ICT device 1. In this embodiment, two indoor air conditioners 51 and 52 are installed. Hereinafter, the indoor air conditioner 5 on the left side of the page is referred to as a first indoor air conditioner 51, the indoor air conditioner 5 on the right side of the page is referred to as a second indoor air conditioner 52, and these indoor air conditioners 51 and 52 are collectively referred to as indoor air conditioners. It is described as Machine 5.

  The first indoor air conditioner 51 and the second indoor air conditioner 52 are indoor air conditioners having the same structure. That is, as shown in FIG. 2, the first indoor air conditioner 51 and the second indoor air conditioner 52 include an air handling unit (AHU) having coolers 51A and 52A, flow rate adjusting valves 51B and 52B, blowers 51C and 52C, and the like. It is composed of.

  The coolers 51A and 52A cool the air by exchanging heat between the cold water supplied from the heat source device 7 and the air supplied to the room. The heat source device 7 generates cold heat. The cold heat is supplied to the coolers 51A and 52A by cold water as a heat medium.

  The heat medium, that is, cold water is supplied to the coolers 51A and 52A (indoor air conditioner 5) by the primary pump P1 and the secondary pump P2. The flow rate adjusting valves 51B and 52B are provided in the respective coolers 51A and 52A. The flow rate adjusting valves 51B and 52B adjust the circulation amount of cold water supplied to the coolers 51A and 52A.

  For this reason, the temperature of the cold water supplied to the cooler 51A (referred to as the first cooler 51A) and the temperature of the cold water supplied to the cooler 52A (referred to as the second cooler 52A) are the same temperature. On the other hand, the amount of circulating water in the first cooler 51A and the amount of circulating water in the second cooler 52A vary according to the cooling capacity required for each indoor air conditioner 5.

The heat source unit 7A is configured by a vapor compression refrigerator that circulates a refrigerant such as chlorofluorocarbon to move the heat on the low temperature side to the high temperature side. The cooling tower 7B cools the cooling water by exchanging heat between the cooling water heat-exchanged with the refrigerant and at least one of air and water.

2.2 Capability Control of Air Conditioning System The cooling capacity generated in each cooler 5 includes the flow rate adjustment valves 51B and 52B, the blower capacity of the fans 51C and 52C, and the amount of cold water supplied to the coolers 51A and 52A (two It varies depending on the amount of water delivered by the next pump P2), the temperature of the cold water (the refrigeration capacity generated by the heat source device 7), and the like.

  The refrigerating capacity generated in the heat source device 7, that is, the refrigerating capacity generated in the heat source unit 7A (vapor compression type refrigerating machine) is added to the cooling capacity of the cooling tower 7B, the circulating water amount of the cooling water, etc. It varies depending on the rotational speed of the provided compressor and the opening degree of the expansion valve.

  The integrated control device 10 includes an air conditioner control unit 10A, a secondary pump control unit 10B, a primary pump control unit 10C, a heat source control unit 10D, a cooling water pump control unit 10E, and a cooling tower control unit 10F. Indirectly control each component device.

  The air conditioner control unit 10A controls the operation of the indoor air conditioner 5, that is, the flow rate adjusting valves 51B and 52B and the blowers 51C and 52C. The secondary pump control unit 10B controls the amount of cold water supplied to the indoor air conditioner 5 by controlling the operation of the secondary pump P2.

  The primary pump control unit 10C controls the operation of the primary pump P1. The heat source control unit 10D controls the heat source unit 7A, that is, the rotational speed of the compressor, the opening degree of the expansion valve, and the like. The cooling water pump control unit 10E controls the operation of the cooling water pump P3 to control the circulation amount of the cooling water. The cooling tower control unit 10F controls the amount of air blown from the outdoor blower (not shown) and the amount of water sprayed from the water sprinkler (not shown).

  The integrated control device 10 and the control units 10A to 10F are configured by a computer having a CPU, a ROM, a RAM, and the like. A program for executing control of each device is stored in advance in a nonvolatile storage unit such as a ROM provided in the integrated control device 10 and the control units 10A to 10F.

2.3 Control of Air Conditioning System by Integrated Control Device etc. Each control unit 10A to 10F has a drive circuit that drives a control target of the control unit, and directly controls the control target. The integrated control device 10 issues a control command signal to each of the control units 10A to 10F.

That is, after receiving the control command signal from the integrated control device 10, each of the control units 10A to 10F autonomously executes specific control for realizing the content of the control command signal.
For example, each indoor air conditioner 5 is provided with a blown air temperature sensor S1 and an intake air temperature sensor S2. Each blown air temperature sensor S1 detects the temperature of air supplied to the room from the indoor air conditioner 5, that is, the temperature of heat that has been subjected to heat exchange in the coolers 51A and 52A (hereinafter referred to as blown air temperature).

  Each intake air temperature sensor S2 detects the temperature of the air before heat exchange in the coolers 51A and 52A, that is, the temperature of the air sucked into each indoor air conditioner 5 (hereinafter referred to as the intake air temperature). Each intake air temperature sensor S <b> 2 detects the temperature of the air sucked into the indoor air conditioner 5 from the upper side in the vertical direction of each indoor air conditioner 5.

  The air conditioner control unit 10A adjusts each flow rate so that the temperature difference between the blown air temperature and the intake air temperature becomes the “target temperature difference (hereinafter, target temperature difference ΔTo)” set by the integrated control device 10. The valves 51B and 52B and the fans 51C and 52C are controlled.

  That is, the air conditioner control unit 10A autonomously controls the operation of the indoor air conditioner 5 so that the current target temperature difference ΔTo becomes the current target temperature difference ΔTo unless the new target temperature difference ΔTo is set by the integrated control device 10.

  Specifically, when the difference between the current temperature difference and the target temperature difference ΔTo increases in the area where the first ICT device 1A is installed, the air conditioner control unit 10A determines the opening degree of the flow rate adjustment valve 51B and the first blower. The cooling capacity of the first indoor air conditioner 51 is increased by increasing the air flow rate of 51C.

  When the difference between the current temperature difference and the target temperature difference ΔTo becomes small in the area where the first ICT device 1A is installed, the air conditioner control unit 10A determines the opening degree of the flow rate adjustment valve 51B and the blast amount of the first blower 51C. The cooling capacity of the first indoor air conditioner 51 is reduced from the current time by reducing the size.

  Similarly, when the difference between the current temperature difference and the target temperature difference ΔTo increases in the area where the second ICT device 1B is installed, the air conditioner control unit 10A determines the opening degree of the flow rate adjustment valve 52B and the second blower 52C. The cooling capacity of the second indoor air conditioner 52 is increased by increasing the air flow rate.

  When the difference between the current temperature difference and the target temperature difference ΔTo becomes small in the area where the second ICT device 1B is installed, the air conditioner control unit 10A determines the opening degree of the flow rate adjustment valve 52B and the blower amount of the second blower 52C. The cooling capacity of the second indoor air conditioner 52 is reduced from the current time by reducing the size.

  The target temperature difference ΔTo is a value stored in the integrated control device 10 or the air conditioner control unit 10A as a preset fixed value, a value determined by the integrated control device 10 according to a predetermined rule, or the like. Any of them may be used.

  The “predetermined rule” is, for example, a target temperature based on a temperature difference between a preset target indoor air temperature and an actual indoor air temperature (temperature detected by the room temperature sensor S5). For example, a rule for determining the difference ΔTo.

  As long as the primary pump control unit 10C and the secondary pump control unit 10B do not receive a flow rate change command from the integrated control device 10, chilled water with a preset flow rate (hereinafter also referred to as a target chilled water circulation rate) circulates. The primary pump P1 and the secondary pump P2 are autonomously controlled.

  Then, when the primary pump control unit 10C and the secondary pump control unit 10B receive the flow rate change command from the integrated control device 10, the primary pump P1, the secondary pump is set with the received new circulation amount as the target cold water circulation amount. The pump P2 is controlled autonomously.

  On the discharge side of the primary pump P1 or the secondary pump P2 (in this embodiment, the primary pump P1), a cold water temperature sensor S3 that detects the temperature of the cold water is provided. The heat source control unit 10D autonomously controls the operation of the heat source unit 7A so that the cold water temperature detected by the cold water temperature sensor S3 becomes the “target cold water discharge temperature” set by the integrated control device 10. To do.

  The cooling water pump control unit 10 </ b> E autonomously controls the operation of the cooling water pump P <b> 3 so that the cooling water circulation amount becomes the “target cooling water circulation amount” set by the integrated control device 10.

  The cooling tower control unit 10F autonomously operates the cooling tower 7B so that the temperature of the cooling water cooled by the cooling tower 7B becomes the “target cooling water temperature” set by the integrated control device 10. To control. The “cooling water temperature” is detected by the cooling water temperature sensor S4.

3. Operation control of each ICT device 3.1 Overview of operation control (see Fig. 3)
The operation state (operation rate) of each ICT device 1 is controlled by the operation control unit 20. The operation control unit 20 includes a request amount determination unit and a processing amount determination unit. The request amount determination unit determines the total amount of processing requests based on processing requests from at least one terminal device.

  The processing amount determination unit determines the execution processing amount of each of the plurality of ICT devices 1. The operation control unit 20 controls the operation state (operation rate) of the ICT device 1 according to the execution processing amount determined by the processing amount determination unit.

  The processing amount determination unit can determine the execution processing amount of each ICT device 1 in the normal mode or the power saving mode. In the normal mode, the processing amount determination unit determines the execution processing amount of each ICT device 1 based on the operation rate determined by the request amount determination unit.

  In the power saving mode, the processing amount determination unit determines the execution processing amount of each ICT device 1 based on the operating rate of the equipment device (in the present embodiment, each indoor air conditioner 5). Note that the processing amount determination unit according to the present embodiment determines the execution processing amount in any mode in accordance with an instruction from a person who manages the server room.

  The “execution processing amount of the ICT device 1 (hereinafter also including the virtual information processing device)” refers to the information processing amount actually executed by the ICT device 1 (hereinafter referred to as the actual processing amount) and the ICT. This is the information processing amount of at least one of the information processing amounts scheduled to be executed by the apparatus 1 (hereinafter referred to as “expected processing amount”).

  Therefore, for example, when the breakdown of the execution processing amount is only the expected processing amount (execution processing amount = expected processing amount), at least the ICT device 1 that can execute the processing, that is, the ICT device 1 that is not in the stopped state is at least There is one.

  As the execution processing amount increases, the number of ICT devices 1 that can execute processing and the number of ICT devices 1 that actually execute processing (hereinafter collectively referred to as active ICT devices) are stepwise. To increase. That is, when the increase / decrease amount of the execution processing amount exceeds, for example, a preset increase / decrease amount, the number of operating ICT devices changes.

  “The operating rate of the equipment (in this embodiment, each indoor air conditioner 5)” is the ratio of “the current refrigeration capacity and the necessary refrigeration capacity” to “the maximum refrigeration capacity that can be generated in each indoor air conditioner 5”. Or the “current refrigeration capacity and necessary refrigeration capacity” itself refers to the size. “Necessary refrigeration capacity” refers to a control target refrigeration capacity such as a refrigeration capacity necessary for setting the target temperature difference ΔTo, for example.

  The operation control unit 20 is configured in a computer having a CPU, a ROM, a RAM, and the like, and its operation is realized according to a program stored in advance in a nonvolatile storage unit such as a ROM. The required amount determination unit and the processing amount determination unit according to the present embodiment are realized by the above program.

2.2 Power saving mode control <Overview of power saving mode control>
When the power saving mode is selected by the administrator, the operation control unit 20 determines the execution processing amount of each of the plurality of ICT devices 1 based on the operation rate of each indoor air conditioner 5. The operation control unit 20 recognizes the operation rate of each indoor air conditioner 5 via the integrated control device 10.

<Centralized control method>
The centralized control method is a control method that is executed when the operating rate Ro of any one of the indoor air conditioners 5 is less than the first operating rate R1. That is, the operation control unit 20 performs processing on any one of the plurality of ICT devices 1 when the operation rate Ro of any indoor air conditioner 5 is less than the preset first operation rate R1. Concentrate execution.

  That is, the operation control unit 20 determines that at least one ICT device from among the plurality of ICT devices 1 according to a preset rule when the operation rate Ro of any one of the indoor air conditioners 5 is less than the first operation rate R1. 1 is set to the stopped state, and the ICT device 1 that is not in the stopped state is set to a state in which processing can be executed.

  For example, when the operation rate Ro of any one of the indoor air conditioners 5 becomes less than the first operation rate R1, the operation control unit 20 causes the ICT device 1 (hereinafter referred to as centralized operation) to concentrate the execution of processing according to a preset rule. Select ICT equipment).

  Thereafter, the operation control unit 20 shifts the processing that has been processed by the other ICT devices 1 to the central operation ICT device to increase the execution processing amount of the central operation ICT device, and at least one of the other ICT devices 1. The ICT device 1 of the stand is brought into a stopped state.

  Then, the operation control unit 20 stops the power supply device that supplies power to the ICT device 1 that is in the stopped state and the indoor air conditioner 5 that blows cooling air to the ICT device 1 that is in the stopped state. A command signal is issued to the power feeding device and the indoor air conditioner 5 (integrated control device 10).

  Specifically, for example, when the operation rate Ro of the second indoor air conditioner 52 becomes less than the first operation rate R1, the operation control unit 20 performs the process executed by the second ICT device 1B as the first ICT device. While shifting to 1A, the 2nd ICT apparatus 1B is made into a halt condition.

  For this reason, the 2nd indoor air conditioner 52 which supplies cold air to the 2nd ICT apparatus 1B stops, and the electric power feeder which supplies electric power to the 2nd ICT apparatus 1B stops. Therefore, the operation rate of the indoor air conditioner 5 that supplies cold air to the central operation ICT device and the operation rate of the power supply device that supplies power to the central operation ICT device increase.

  That is, the “first operating rate R1” means that at least one of the plurality of indoor air conditioners 5 is stopped and the refrigerating capacity of the indoor air conditioner 5 stopped by the other indoor air conditioners 5 is supplemented. Is the availability rate.

<First distributed control method>
The first distributed operation method is a control method that is executed when the operation rate Ro of each indoor air conditioner 5 is equal to or higher than the first operation rate R1.

  That is, the operation control unit 20 determines the execution processing amount of each of the plurality of ICT devices 1 based on the decrease amount when the operation rate Ro decreases when the operation rate Ro is equal to or higher than the first operation rate R1.

  Further, when the operation rate Ro increases when the operation rate Ro is equal to or higher than the first operation rate R1, the operation control unit 20 determines the execution processing amount of each of the plurality of ICT devices 1 based on the increase amount.

  Specifically, when both the first indoor air conditioner 51 and the second indoor air conditioner 52 are operating, for example, the operating rate of the first indoor air conditioner 51 is higher than the operating rate of the second indoor air conditioner 52. In this case, the operation control unit 20 shifts a part of the processing being executed by the second ICT device 1B to the first ICT device 1A.

  Thereby, in 2nd ICT equipment 1B, the amount of execution processing according to the amount of reduction of the operation rate of the 2nd indoor air conditioner 52 is determined, and in 1st ICT equipment 1A, the operation rate of the 1st indoor air conditioner 51 rises. The execution processing amount corresponding to the amount is determined.

<Second distributed control method>
The second distributed control method is a control method that is executed when the operation rate Ro of any one of the indoor air conditioners 5 is greater than the preset second operation rate R2. Note that the second operating rate R2 is larger than the first operating rate R1.

  That is, for example, when the operation rate Ro of the first indoor air conditioner 51 is larger than the second operation rate R2, the operation control unit 20 can execute the process in the first ICT equipment 1A that the first indoor air conditioner 51 takes charge of. The number of ICT devices 1 is increased compared to when the operation rate Ro is equal to or less than the second operation rate R2.

<Third distributed control method>
The third distributed control method is a control method that is executed when the operating rate Ro of any of the indoor air conditioners 5 exceeds the preset third operating rate R3. The third operating rate R3 is a value larger than the second operating rate.

  That is, when the operation rate Ro of any one of the indoor air conditioners 5 exceeds the third operation rate R3, the operation control unit 20 determines the number of executable ICT devices 1 and the operation rate Ro is the third operation rate. Reduce compared to R3 or lower.

  That is, in the third distributed control method, in any of the indoor air conditioners 5, when the refrigeration capacity margin falls below a predetermined predetermined margin, or the refrigeration capacity margin can fall below the predetermined margin. This is a control method that ensures air conditioning capacity in preparation for an unexpected situation by securing a predetermined margin when performance is high.

<Details of power saving mode control>
FIG. 4 is an example of a flowchart showing details of the power saving mode control. A program for executing the flow church shown in FIG. 4 is executed by the operation control unit 20. When this program is started, first, the operating rate Ro of each indoor air conditioner 5 is determined (S1).

  Next, it is determined whether each operating rate Ro is equal to or higher than the first operating rate R1 (S3). When it is determined that the operating rate Ro is equal to or higher than the first operating rate R1 (S3: YES), it is determined whether the operating rate Ro is equal to or higher than the second operating rate R2 (S5).

  When it is determined that the operating rate Ro is equal to or higher than the second operating rate R2 (S5: YES), it is determined whether the operating rate Ro is equal to or higher than the third operating rate R2 (S7). When it is determined that the operating rate Ro is less than the third operating rate R3 (S7: NO), after the number of executable ICT devices 1 is increased to a number corresponding to the size of the operating rate Ro (S9) The execution processing amount of each of the plurality of ICT devices 1 is determined (S11), and then S1 is executed again.

  When it is determined in S5 that the operation rate Ro is less than the second operation rate R2 (S5: NO), the number of executable ICT devices 1 is not increased and each of the plurality of ICT devices 1 is increased. The execution processing amount is determined (S11).

  If it is determined in S7 that the operating rate Ro is equal to or higher than the third operating rate R3 (S7: YES), the number of executable ICT devices 1 is decreased or the executable ICT device 1 Without increasing the number (S13), the execution processing amount of each of the plurality of ICT devices 1 is determined (S11).

When it is determined in S3 that the operation rate Ro is not equal to or higher than the first operation rate R1 (S3: NO), the operation control unit 20 concentrates the process on any ICT device 1 (S13).
3.

As a result, the power consumption of the information processing system can be reduced.

  Further, since the operation control unit 20 concentrates processing on any ICT device 1, it is possible to reduce the number of ICT devices 1 in a standby state (idling state). Therefore, it is possible to reduce the power consumption necessary for operating the ICT device 1. As a result, the power consumption of the indoor air conditioner 5 (air conditioning system) can also be reduced.
