Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram showing a configuration of an air conditioning control system 1 according to the present embodiment. The air conditioning control system 1 includes a plurality of air conditioners 10 (air conditioner 10-1, air conditioner 10-2, air conditioner 10-3) installed in a room to be air conditioned, and each air conditioner 10 is air conditioned. Sensor 20 (sensor 20-1, sensor 20-2, sensor 20-3) installed in each zone to be operated, air conditioner 10 and air conditioner control device 100 connected to sensor 20 are provided. Here, the plurality of air conditioners 10 (the air conditioners 10-1, the air conditioner 10-2, and the air conditioner 10-3) have the same configuration, and are described as the air conditioners 10 when there is no need to individually explain them. The plurality of sensors 20 (sensor 20-1, sensor 20-2, sensor 20-3) have the same configuration, and will be described as sensors 20 when there is no need to explain them individually.

  A plurality of racks in which computer devices and the like are installed are provided in a room to be air-conditioned by the air conditioning control system 1. The first zone in which the air conditioner 10-1 is in charge of cooling, the second zone in which the air conditioner 10-2 is in charge of cooling, and the third zone in which the air conditioner 10-3 is in charge of cooling are the main zones. It is the space used as the object of air-conditioning control in an embodiment. Such a zone is determined in advance in order to keep the indoor environment in the zone in a stable state based on the calorific value of the computer equipment or rack installed in the zone and the ability of the air conditioner 10 in charge of air conditioning of the zone. It is an area that is In this way, each air conditioner 10 cools a space to be controlled called a predetermined zone. That is, the zone virtually divides the air-conditioning control target area into a plurality of areas, and uses the divided area as a zone to air-condition the zone to which one or a plurality of air conditioners 10 are allocated. Here, the range of the region and the heat generation amount of the rack may be different depending on the zone, and the temperature setting of each air conditioner 10 may be different. The air conditioner 10 appropriately cools the zone that it is in charge of according to the amount of heat generated by the racks arranged in each zone.

  The air conditioner 10 performs air conditioning and cooling of the zone according to the indoor state of the zone that it is in charge of. The air conditioner 10 includes a computer device having a control unit that controls its own operation, a storage unit, and the like. The air conditioner 10 includes a detection unit 11. The detection part 11 is comprised with the temperature sensor and humidity sensor with which self is provided, and detects the value (for example, temperature and humidity) which shows the indoor state around self. The air conditioner 10 performs air conditioning control based on indoor state information generated according to a value indicating the indoor state acquired by the detection unit 11. The air conditioner 10 stores a preset value such as a preset temperature or preset humidity in its storage unit, and a measured value such as temperature or humidity detected by the detector 11 exceeds the set value range. In such a case, the air-conditioning load is increased and the indoor environment is maintained at a set value.

In addition, the air conditioner control device 100 has its own supply air temperature (T _sa ), supply air volume (F _sa ), current performance (Q), outside air temperature (T _oa ) acquired by the detection unit 11, and outside air humidity. Air conditioner state information including information indicating the state of itself and its surrounding environment such as (W _oa ) is output to the air conditioner control device 100.
The sensor 20 is installed in a zone to be air-conditioned by any one of the air conditioners 10 and detects the temperature and humidity at that point, or the heat generation amount (power consumption) of the rack installed in the zone, and the zone state Information is output to the air conditioner control device 100.

  The air conditioner control device 100 includes an indoor state acquisition unit 110, a disturbance value calculation unit 130, a zone information storage unit 120, an indoor state information storage unit 140, an indoor state prediction unit 150, an operation control unit 160, an expectation A capability calculation unit 170, an air conditioner information storage unit 180, and an output unit 190 are provided, and the air conditioning operations of the plurality of air conditioners 10 are controlled.

  The indoor state acquisition unit 110 acquires indoor state information of air conditioner state information output from each of the plurality of air conditioners 10 and zone state information output from the plurality of sensors 20. The indoor state acquisition unit 110 can calculate a change in the indoor environment by acquiring indoor state information at each predetermined measurement timing.

  In the zone information storage unit 120, zone information relating to each zone in the room to be air-conditioned is stored. In the zone information, the identification information of the air conditioner in charge of the corresponding zone, the result value of the annual load calculation in the corresponding zone, the heat capacity and time constant of the corresponding zone, the identification information of the adjacent zone, and the adjacent Zone information including information on the contact area with the zone is stored in advance.

The disturbance value calculation unit 130 indicates a disturbance that is an uncertain factor for a change in the indoor environment based on the indoor state information acquired by the indoor state acquisition unit 110 and the heat capacity of the zone stored in the zone information storage unit 120. It is a calculating part which calculates a disturbance value. The disturbance value calculation unit 130 obtains Q _other indicating the disturbance of the zone according to the following thermal balance equation (1).

Here, (C _fur + C _air ) on the left side is a constant indicating the heat capacity of the zone, and is stored in advance in the zone information storage unit 120. As shown in FIG. 2, dT _i ÷ dt is a measured value indicating a change in room temperature according to time. A term indicated by a dot added to the upper part of Q _equip (hereinafter referred to as Q _equip (dot)) is a measured value indicating power consumption. Q _wall (dot) is a through-flow heat from the outside world, and is estimated from the thermal load calculation result stored in the zone information storage unit 120. Here, based on the annual heat load calculation result, a scatter diagram of the once-through heat load as shown in FIG. 3 is generated in advance. Thereby, the once-through heat load according to the outside air temperature and the room temperature can be calculated.

Q _ml (dot) is the inflow heat from the adjacent room zone and the amount of heat transferred. Q _ml (dot) is calculated based on, for example, a mixed loss model of HVACSIM + which is a dynamic simulation. For example, as shown in FIG. 4, when the zones of Zone 1 and Zone 2 are adjacent to each other, the height of the zone in Zone 1 is H, the width of the zone is W, and the ground contact surface of another zone from the supply point from the air conditioner in the zone Up to XLP, the volume of the zone is V1, the room temperature is T1, the supply air volume from the air conditioner is G1, and the supply temperature is SAT1. Similarly, if each value in Zone 2 is defined, the inflow heat can be calculated by the program expression shown in FIG. In FIG. 5, the heat amount (kcal) of the mixing loss of Zone 1 is calculated as XML1, and the heat amount (kcal) of the mixing loss of Zone 2 is calculated as XML2. The values of XML1 and XML2 are each multiplied by 1/860 to change the unit to kw, and the amount of heat transferred can be calculated as OUT (1) or OUT (2).

Q _S (dot) in the above formula (1) is the amount of heat supplied from the air conditioner, and can be determined from the measured value by F _sa × (T−T _sa ). Q _other (dot) indicates a disturbance that is an uncertain factor with respect to a change in the indoor environment, and is another amount of heat. This _Qother (dot) cannot be measured, and _Qother (dot) is obtained by solving the above equation (1) for this term. Here, when any one of the plurality of air conditioners 10 fails, the load of the failed air conditioner 10 may be allocated to the adjacent air conditioners 10. For example, as shown in FIG. 6, when the air conditioner 10-2 fails, the air conditioner 10-1 is responsible for the fourth zone and the air conditioner 10-3 is responsible for the fifth zone. -2 is allocated to the air conditioner 10-1 and the air conditioner 10-3. Also, the disturbance value calculation unit 130 causes the indoor state information storage unit 140 to store the values used in the equation (1) and the calculated Q _other (dot) value.

Similarly, X _other is calculated by the following equilibrium equation (2) regarding humidity. Here, ρ _i V _i e _m is a constant indicating the water content of the zone. dW _i ÷ dt is a measurement value indicating a change in absolute humidity. Q _equip ÷ h _fg is a measured value indicating the latent heat load from the device. F _sa (dot) (A _sa −W _i ) is a measured value indicating the supply load from the air conditioner. X _other (dot) indicates a disturbance that is an uncertain factor with respect to a change in the indoor environment, and is another amount of heat.

  The room state information storage unit 140 stores the room state information acquired by the room state acquisition unit 110 and the disturbance value calculated by the disturbance value calculation unit 130. The room state information storage unit 140 stores values acquired by the room state acquisition unit 110 at regular intervals and calculated by the disturbance value calculation unit 130. FIG. 7 is a diagram illustrating a data example of room state information stored in the room state information storage unit 140. As shown in FIG. 7, the indoor state information storage unit 140 stores the latest (t) indoor state information acquired by the indoor state acquisition unit 110 and a predetermined interval before (t−1, t−2,... ) Is stored.

  The indoor state prediction unit 150 is based on the indoor state information stored in the indoor state information storage unit 140, and after a certain time (t + 1, t + 2, Predict the room temperature at t + 3,. For example, as shown in FIG. 8, the indoor state prediction unit 150 includes indoor state information including power consumption, once-through heat, inflow heat, heat supplied from the air conditioner, and other heat amounts stored in the room state information storage unit 140. From the value, a predicted value of future indoor state information is calculated by moving average. Moreover, the indoor state prediction unit 150 calculates a future room temperature change by the following equation (3) based on the predicted value of the indoor state information.

And based on said Formula (3), the predicted value of future room temperature (T _{i, t + 1} ) is calculated by the following Formula (4). Here, it is assumed that the time constant τ is known.

From the above formula (3) and the above formula (4), the room temperature can be calculated by adding a first-order lag element to the heat balance when the room is assumed to be completely confused. Similarly, the indoor humidity _{Wi, t + 1} can also be calculated.
The operation control unit 160 inputs the predicted value of the future room temperature calculated by the room state information storage unit 140 to each detection unit 11 included in the air conditioner 10, thereby depending on the measurement timing by the detection unit 11 and the sensor 20. First, the indoor state information is input to the air conditioner 10 to control the air conditioning.

  The air conditioner information storage unit 180 stores air conditioner information indicating the device characteristics of the air conditioner 10. The device characteristics are information related to the air conditioner provided in advance by the air conditioner manufacturer, and are expressed by a coefficient of performance COP (Coefficient of Performance). For example, the air conditioner information provided from the manufacturer includes a capability value representing the maximum capacity of the air conditioner 10 by taking into consideration the COP characteristic with respect to the outside air and the COP characteristic with respect to the room temperature.

The expected capacity calculation unit 170 calculates the predicted value of the expected capacity of the air conditioner 10 that keeps the indoor environment of the zone at the set value according to the future predicted value of the room temperature calculated by the indoor state prediction unit 150. The expected capacity calculation unit 170 outputs a warning to the output unit 190 when the predicted value of the calculated expected capacity exceeds the capacity value of the corresponding air conditioner 10 stored in the air conditioner information storage unit 180. For example, the expected capacity calculation unit 170 obtains the specific enthalpy h _{i, n} of the room air from the combination of room temperature and humidity stored in the room state information storage unit 140. The expected capacity calculation unit 170 obtains the specific enthalpy h _{sa, n} of the supply air from the combination of the supply air temperature and humidity of the air conditioner stored in the indoor state information storage unit 140. Further, the expected capacity calculation unit 170 obtains the specific enthalpy h _{oa, n} of the room air from the combination of the outside air temperature and the humidity stored in the room state information storage unit 140. Here, the capacity of the air conditioner is Q _n = F _sa × (hi _{, n−} h _{sa, n} ). The expected capacity calculation unit 170 stores information corresponding to a table as shown in FIG. 9 indicating the expected capacity value of the air conditioner according to the outside air temperature and the room temperature in its own storage area. Calculate the expected capacity of the air conditioner according to Further, the expected capacity calculation unit 170 may compare the specific enthalpy of the room and the specific enthalpy of the outside air, estimate the outside air cooling operation time, and control the operation of a ventilation fan (not shown). When the room is set to a certain temperature at a specific time, the air conditioning operation change time may be estimated from the indoor trend indicated by the indoor state information stored in the indoor state information storage unit 140.

  The output unit 190 outputs an alarm input from the expected ability calculation unit 170. The output unit 190 is, for example, a display, and performs predetermined image processing on the screen information input from the expected ability calculation unit 170 and displays an alarm on the screen. Further, for example, the output unit 190 may output a warning sound as a speaker.

Next, an operation example in which the air conditioning control system 1 according to the present invention controls air conditioning will be described with reference to FIG.
First, the indoor state acquisition unit 110 acquires indoor state information of air conditioner state information output from each of the plurality of air conditioners 10 and zone state information output from the plurality of sensors 20 (step S1). Here, as shown in FIG. 7, the indoor state information storage unit 140 stores the indoor state information at the measurement time point between the current time point (t) and the time point (t−1) before a certain interval. The disturbance value calculation unit 130 calculates a disturbance value for the zone to be air-conditioned based on the indoor state information acquired by the indoor state acquisition unit 110 and the heat capacity of the zone stored in the zone information storage unit 120 (step S2). ). Then, the indoor state prediction unit 150 is based on the indoor state information stored in the indoor state information storage unit 140 after a certain time (for example, t) when the indoor state acquisition unit 110 acquires the latest indoor state ( For example, a predicted value of room temperature at t + 1) is calculated (step S3).

  The operation control unit 150 inputs the predicted value of the room temperature calculated by the room state information storage unit 140 to each detection unit 11 provided in the air conditioner 10, and controls the operation of the air conditioner 10 (step S4). Then, the expected capacity calculation unit 170 calculates the predicted value of the expected capacity of the air conditioner 10 that operates so as to keep the indoor environment of the zone at the set value in accordance with the future predicted value of the room temperature calculated by the indoor state prediction unit 150. Calculate (step S5). When the expected capacity calculation unit 170 determines that the calculated predicted values of the plurality of expected capacities exceed the capability values of the corresponding air conditioner 10 stored in the air conditioner information storage unit 180 (step S6: YES) ), A warning is output to the output unit 190 (step S7).

  On the other hand, when the expected capacity calculation unit 170 determines in step S6 that the predicted value of the calculated expected capacity does not exceed the capacity value of the corresponding air conditioner 10 stored in the air conditioner information storage unit 180, the disturbance value The calculating unit 130 determines whether or not a predetermined time has elapsed (step S8). Here, the fixed time is an interval shorter than the measurement timing, and the air conditioner control device 100 predicts the disturbance value and inputs the predicted value of the room temperature to the air conditioner 10 to control the operation of the air conditioner 10. It is decided according to. When the disturbance value calculation unit 130 determines that a certain time has elapsed (step S8: YES), it determines whether it is a predetermined measurement timing (step S9).

  If the disturbance value calculation unit 130 determines in step S9 that the measurement timing is not predetermined (step S9: NO), the process returns to step S2, and thereafter, from step S2 to step S8 until the measurement timing is reached. Repeat the process. On the other hand, if the disturbance value calculation unit 130 determines in step S9 that it is a predetermined measurement timing (step S9: YES), the process returns to step S1. Then, the indoor state acquisition unit 110 acquires the indoor state information of the air conditioner state information output from each of the plurality of air conditioners 10 and the zone state information output from the plurality of sensors 20 again, from step S1. The process up to step S9 is repeated.

As described above, according to the present embodiment, the room state prediction unit 150 predicts and calculates the future room temperature of the zone before the room temperature rises and the rack is burdened. Thus, it is possible to perform control for immediately increasing the load of the air conditioner and lowering the temperature by inputting the predicted room temperature value to the air conditioner 10.
Further, according to the present embodiment, even if any one of the plurality of air conditioners 10 breaks down, another air conditioner 10 is instantly based on the power consumption of the rack that has been measured until now. Since the predicted room temperature is sent to the room temperature, the room temperature will not be sufficiently high. As a result, the room can be cooled in advance before the rack temperature rises.

In this way, the air conditioner control device 100 quickly acquires the information on the air conditioner 10 and the zone over time, quickly grasps the state of the room, and considers the change state of each zone. Control to keep the zone comfortable.
Even if the air conditioner 10 does not break down, the air conditioner control device 100 uses the estimation method such as moving average based on the power consumption of each zone acquired over time to estimate future rack consumption. By predicting the power, when the room temperature rises, the predicted room temperature can be sent to the air conditioner 10 in advance.

Further, according to the configuration of the air conditioner control device 100 of the present embodiment, the respective calculation units of the disturbance value calculation unit 130, the room state prediction unit 150, and the expected capability calculation unit 170 process the respective processes in parallel. It is possible to reflect the calculation result in the control of the air conditioner 10-1 efficiently and immediately.
Moreover, since each calculating part and each memory | storage part are accommodated in the single computer apparatus, wiring is simplified and it becomes possible to make the air conditioning control system 1 whole compact.

  As described above, according to the present embodiment, by controlling the operation of the air conditioner 10 in advance before the zone temperature rises, the zone can be stabilized without applying an excessive load to the air conditioner 10 or the rack. And can be kept in a cooled state.

  In the present embodiment, the indoor state prediction unit 150 calculates the predicted value of the future indoor information by moving average from the change in the indoor state information with time. For example, a probability density function, a neural network, etc. The predicted value of the future indoor state may be calculated using the above.

In the present embodiment, three air conditioners 10, sensors 20, and zones have been described as examples. However, one or two or more than four may be used. A plurality of sensors 20 may be installed in one zone.
Further, the indoor state acquisition unit 110 may acquire indoor state information indicating a change in the indoor environment at a predetermined interval a plurality of times, or more than a certain amount of indoor state information that enables the indoor state prediction unit 150 to perform prediction processing. After acquiring, the indoor state information may not be newly acquired.

  In the present embodiment, the expected capacity calculation unit 170 compares the calculated expected capacity value with the air conditioning function capability stored in the air conditioner information storage unit 180, and when the air conditioning function capability is lower than the display capability, Although an alarm is output to the output unit 190, a similar alarm may be transmitted to an external building management system or the like via a network.
