Description

  The present invention relates to a control device that controls air conditioning in an air conditioning target area (for example, a production factory) in which equipment that generates heat when operating is installed.

  In a production line for processing or assembling products, a heating device constituting the line, or equipment such as a motor, a controller, and a transformer of the production device generates heat and releases a large amount of heat into the air.

  On the other hand, in clean rooms required for manufacturing semiconductors, etc., printing lines, precision processing lines, etc., air conditioning is performed to keep the temperature in the production plant at a substantially constant value for the purpose of stabilizing the processing accuracy of the products, etc. In order to suppress the temperature rise due to heat radiation from the facility, an air conditioner with high cooling capacity is used.

  For this reason, when the production line is stopped and there is no heat dissipation, a high-capacity air conditioner is activated, and the production factory is cooled beyond the set temperature (overshoot), resulting in wasted power consumption. There was a problem.

As a method for solving such a problem, Patent Document 1 discloses environmental data (air temperature, CO ₂ concentration, power consumption) in an air-conditioning target area, and the operation status of a device in the target area and human activity. There has been proposed a method of changing the set temperature of the air conditioner to an optimum value from the increase / decrease of environmental data that changes depending on the presence or absence. According to the method of Patent Literature 1, since the temperature change in the air conditioning target region can be predicted in advance and the operating capacity of the air conditioner can be set, waste of power consumption due to excessive cooling or the like can be suppressed.

  Furthermore, Patent Document 2 calculates the time required to reach the set temperature from the power consumption of the equipment in the air-conditioning target area and the current temperature, and selects the optimal air-conditioning control pattern from the calculation result to select the power consumption. There has been proposed a method for reducing this.

  However, the method of Patent Document 1 is not suitable for use in a production factory that requires control to a constant temperature because the operating capacity of the air conditioner is set by changing the set temperature. In addition, it is necessary to derive the relationship between the environmental data and the set temperature in advance, but the relationship varies depending on the combination of various data such as the size of the target area, the outside air temperature, equipment, people, and the arrangement of air conditioners. It is difficult to accurately grasp in advance in the production factory.

  Moreover, since the method of Patent Document 2 is control at a constant temperature setting, it can be applied to a production factory, but it is necessary to derive the relationship between environmental data and a control pattern in advance. Therefore, even when the method of Patent Document 2 is applied to a production factory, an accurate relationship among various data combinations such as the size of the target area, the outside air temperature, the device, the person, the arrangement of the air conditioner, etc. The problem remains that it cannot be set.

<Embodiment 1>
(Overall configuration of control system)
Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic diagram showing a production factory to which a control system according to an embodiment of the present invention is applied. FIG. 2 is a block diagram showing a schematic configuration of the control system.

  The control system 1 of this embodiment includes a plurality of production lines (equipment) 11 to 19, a plurality of air conditioners 21 to 28, and a control device 50 installed in one production factory (air conditioning target area) 10. Prepare.

  Each of the production lines 11 to 19 is a facility that generates heat when operated, including various production apparatuses that process or assemble products. Each of the production lines 11 to 19 is connected to wattmeters 41 to 49 that measure the amount of power consumed in the production line.

  The air conditioners 21, 22, 25, and 26 are ceiling-suspended air conditioners, and the air conditioners 23, 24, 27, and 28 are floor-type air conditioners. Each of the air conditioners 21 to 28 is connected to one of the corresponding attached outdoor units 31 to 38. The number of outdoor units connected to the air conditioner is not particularly limited. For example, the air conditioner 24 is connected to two outdoor units 33 and 34, the air conditioner 28 is connected to two outdoor units 37 and 38, and the other air conditioners are connected to one outdoor unit. The air conditioning capability of the air conditioner can be increased by increasing the number of connected outdoor units. Further, one outdoor unit may be shared by a plurality of air conditioners. For example, the air conditioner 21 and the air conditioner 22 share the outdoor unit 31, and the air conditioner 25 and the air conditioner 26 share the outdoor unit 35.

  The air conditioners 21 to 28 are controlled so that the ambient temperature is measured during operation and the measured temperature becomes a predetermined set temperature. For example, during the cooling operation, the air conditioners 21 to 28 perform an operation of lowering the room temperature (temperature lowering operation) when the measured temperature is higher than the set temperature, and temporarily stop when the measured temperature is lower than the set temperature. In the heating operation, the air conditioners 21 to 28 temporarily stop when the measured temperature is higher than the set temperature, and perform an operation (temperature increase operation) for raising the temperature of the room when the measured temperature is lower than the set temperature.

  The control device 50 controls the operations of the plurality of air conditioners 21 to 28. The control device 50 divides the plurality of air conditioners 21 to 28 into a first group that operates regardless of the operation of the production lines 11 to 19 and a second group that is operated and controlled according to the operation of the production line. Control according to the group.

(Configuration of control device)
Next, the internal configuration of the control device 50 will be described. As shown in FIG. 2, the control device 50 includes a group information storage unit 51, an air conditioning-line correspondence table storage unit (facility identification information storage unit) 52, a control unit 53, and an input unit 54. .

  The group information storage unit 51 is a group indicating an air conditioner belonging to the first group that is operated regardless of the operation of the production lines 11 to 19 and an air conditioner belonging to the second group that is operation-controlled according to the operation of the production line. Store information. FIG. 3 is a diagram illustrating an example of group information stored in the group information storage unit 51. As shown in FIG. 3, here, the air conditioners 21 and 25 belong to the first group, and the other air conditioners 22 to 24 and 26 to 28 belong to the second group.

  The group information storage unit 51 stores group information corresponding to a user input to the input unit 54. Therefore, when changing the group to which a certain air conditioner belongs, the user inputs the fact to the input unit 54, and the group information storage unit 51 updates the group information according to the input.

  The air conditioner-line correspondence table storage unit 52 includes, for each of the air conditioners 22 to 24 and 26 to 28 belonging to the second group, air conditioner identification information indicating the air conditioner, and manufacturing installed closest to the air conditioner. An air conditioning-line correspondence table is stored in which first line identification information (first facility identification information) for identifying a line is associated with a first threshold value for determining the stop of the production line. FIG. 4 is a diagram illustrating an example of the air conditioning-line correspondence table stored in the air conditioning-line correspondence table storage unit 52.

  The first threshold value is smaller than the power consumption during a predetermined period (for example, 10 minutes) when the corresponding production line is operating, and is smaller than the power consumption during the predetermined period when the production line is stopped. A slightly larger value is set.

  The air conditioning-line correspondence table storage unit 52 stores an air conditioning-line correspondence table corresponding to a user input to the input unit 54. Therefore, when the layout in the production factory 10 is changed, the user inputs an instruction to change the first line identification information corresponding to the new layout to the input unit 54, and the air conditioning-line correspondence table storage unit 52 performs the air conditioning- Update the line correspondence table.

  The control part 53 controls each air conditioner 21-28 according to a group. The control unit 53 controls the air conditioners 21 and 25 belonging to the first group so as to perform an operation according to a conventional set temperature. That is, the air conditioners 21 and 25 belonging to the first group operate so that the measured temperature becomes the set temperature.

  Moreover, the control part 53 air-conditions the 1st line identification information and 1st threshold value corresponding to the air conditioning apparatus identification information which show the said air conditioning apparatus with respect to each of the air conditioning apparatuses 22-24 and 26-28 which belong to a 2nd group. -Read from the line correspondence table. Based on the measurement data of the wattmeter connected to the production line indicated by the read first line identification information, the control unit 53 uses the power consumption amount for a predetermined period (for example, a period 10 minutes past the current time) ( Hereinafter, the first power consumption amount) is calculated and compared with the first threshold value.

  As described above, the first threshold value is smaller than the power consumption amount in a predetermined period (for example, 10 minutes) when the production line is operating (operating), and the predetermined period when the manufacturing line is stopped. A value slightly larger than the amount of power consumption in is set. Therefore, when the calculated first power consumption amount is lower than the first threshold, the control unit 53 can determine that the production line indicated by the first line identification information is stopped. When the calculated first power consumption is equal to or greater than the first threshold, the control unit 53 can determine that the production line indicated by the first line identification information is operating.

  When the control unit 53 determines that the production line is stopped, the control unit 53 stops the operation of the air conditioner during the cooling operation, and operates the air conditioner during the heating operation. On the other hand, when it is determined that the production line is operating, the control unit 53 operates the air conditioner during the cooling operation and stops the air conditioner during the heating operation. The air conditioner controlled to operate by the control unit 53 is controlled so that the measured temperature becomes the set temperature.

  As described above, the control unit 53 divides the plurality of air conditioners 21 to 28 into the first group and the second group, and the air conditioners 21 and 25 belonging to the first group are related to the operating state of the production lines 11 to 19. The air conditioners 22 to 24 and 26 to 28 belonging to the second group are controlled according to the operating states of the production lines 11 to 19. Therefore, the second group of air conditioners 22 to 24 and 26 to 28 can be operated according to the heat radiation amount of the production lines 11 to 19. As a result, the second group of air conditioners 22 to 24 and 26 to 28 can avoid unnecessary operation in accordance with the heat radiation from the production lines 11 to 19 and can save power. For example, when the production lines 11 to 19 are stopped and there is no heat dissipation, useless operation can be avoided by stopping the cooling operation of the air conditioners 22 to 24 and 26 to 28 of the second group. The air conditioners 21 and 25 belonging to the first group are operated regardless of the operating states of the production lines 11 to 19. Therefore, for example, at the time of cooling operation, the temperature in the production factory is maintained at the set temperature by the air conditioner belonging to the first group even when the equipment is not operating.

  As described above, the temperature of the production factory can be kept constant without consuming wasteful power by a simple setting of dividing the plurality of air conditioners 21 to 28 into the first group and the second group. That is, it is not necessary to acquire in detail the environmental data that changes according to the conditions of the production factory as in Patent Documents 1 and 2. Further, even if the layout of the equipment and air conditioners in the air conditioning target area is changed, it is not necessary to acquire environmental data as in Patent Documents 1 and 2 again.

(Flow of control processing of air conditioner (during cooling operation))
Next, an example of control processing of the air conditioners 21 to 28 in the present embodiment will be described with reference to FIG. FIG. 5 is a flowchart showing a flow of control processing of the air conditioners 21 to 28 in the present embodiment. In addition, FIG. 5 is an example in the case of air-conditioning operation of the air conditioners 21-28 in summer.

  First, the control unit 53 selects one of the air conditioners 21 to 28 to be controlled. Then, the control unit 53 determines whether or not the air conditioner to be controlled belongs to the second group (S1). The control unit 53 determines S1 by referring to the group information stored in the group information storage unit 51.

  When the air conditioner to be controlled does not belong to the second group (No in S1), that is, when the air conditioner to be controlled belongs to the first group, the control unit 53 uses the air conditioner to control the air conditioner to be controlled. The measured temperature is compared with the set temperature (S2). When the measured temperature is higher than the set temperature (Yes in S2), the control unit 53 causes the air-conditioning apparatus to be controlled to perform a temperature lowering operation (S3). On the other hand, when the measured temperature is equal to or lower than the set temperature (No in S2), the control unit 53 temporarily stops the air conditioner to be controlled (S4).

  When the air conditioner to be controlled belongs to the second group (Yes in S1), the control unit 53 air-conditions the first line identification information and the first threshold corresponding to the air conditioner identification information indicating the air conditioner to be controlled. Read from the line correspondence table (S5). Thereby, the control part 53 can pinpoint the manufacturing line nearest to the air conditioner of control object.

  Next, the control unit 53 determines the first period of a predetermined period (for example, a period of 10 minutes past the current time) from the measurement data of the wattmeter connected to the production line indicated by the first line identification information read in S5. One power consumption is calculated. The control unit 53 can calculate the first power consumption amount by accumulating the past measurement data of the wattmeters 41 to 49 corresponding to the respective production lines 11 to 19. And the control part 53 judges whether the calculated 1st power consumption is more than the 1st threshold value read by S5 (S6).

  When the first power consumption is equal to or greater than the first threshold (Yes in S6), the control unit 53 determines that the production line is operating, and shifts to the process of S2 for the air conditioner to be controlled. That is, the control unit 53 causes the controlled air conditioner to perform a normal operation according to the set temperature without reducing the air conditioning capacity.

  On the other hand, when the first power consumption is less than the first threshold (No in S6), the control unit 53 determines that the production line is stopped, and stops the operation of the controlled air conditioner (S7). . For example, when the first power consumption of the production line 12 indicated by the first line identification information is lower than the first threshold (0.5 kW, see FIG. 4), the control target placed on the floor in the vicinity of the production line 12 The operation of the air conditioner 23 is stopped. Further, when the first power consumption of the production line 15 indicated by the first line identification information is lower than the first threshold (0.3 kW, see FIG. 4), the control target installed immediately above the production line 15 The operation of an air conditioner 26 is stopped. Then, it returns to S1 again and repeats the process of S1-S7.

  The control part 53 performs the process of S1 to S7 about all the air conditioners 21-28.

  As described above, the control unit 53 determines, for each of the air conditioners belonging to the second group, (1) the first power consumption amount of the production line (facility) indicated by the first line identification information corresponding to the air conditioner is predetermined. If the air conditioner is less than the first threshold value, the air conditioner is stopped. (2) If the first power consumption is equal to or greater than the first threshold value, the air conditioner is operated without reducing the air conditioning capacity.

  As a result, the air conditioners 22 to 24 and 26 to 28 belonging to the second group are cooled and operated so that the measured temperature becomes the set temperature only when the nearest production line is operating. It is stopped when the production line installed nearby is stopped. As a result, when the production line is stopped and there is no heat radiation from the production line, the nearby air conditioner is not operated wastefully, and overcooling can be prevented. Further, when the production line is in operation, a nearby air conditioner can be operated, and a temperature increase due to heat radiation from the production line can be effectively prevented.

(Flow of control processing of air conditioner (during heating operation))
Next, another example of the control processing of the air conditioners 21 to 28 in the present embodiment will be described with reference to FIG. FIG. 6 is an example in the case where the air conditioners 21 to 28 are operated for heating in winter.

  First, the control unit 53 performs the same processing of S1 as in FIG. When the air conditioner to be controlled does not belong to the second group (No in S1), that is, when the air conditioner to be controlled belongs to the first group, the control unit 53 uses the air conditioner to control the air conditioner to be controlled. The measured temperature is compared with the set temperature (S8). When the measured temperature is lower than the set temperature (Yes in S8), the control unit 53 causes the air conditioning device to be controlled to perform a temperature raising operation (S9). On the other hand, when the measured temperature is equal to or higher than the set temperature (No in S8), the control unit 53 temporarily stops the air conditioner to be controlled (S4).

  When the controlled air conditioner belongs to the second group (Yes in S1), the control unit 53 performs the processes of S5 and S6 as in the first embodiment. That is, the control unit 53 calculates the first power consumption amount for a predetermined period in the production line closest to the air conditioner to be controlled, and compares it with the first threshold value.

  When the first power consumption is less than the first threshold (No in S6), the control unit 53 determines that the production line is stopped, and shifts to the process of S8 for the air conditioner to be controlled. That is, the air conditioner to be controlled is caused to perform a normal operation according to the set temperature without lowering the air conditioning capacity.

  On the other hand, when the first power consumption is equal to or greater than the first threshold (Yes in S6), the control unit 53 determines that the production line is operating and stops the operation of the air conditioner to be controlled (S7). . Then, it returns to S1 again and repeats the process of S1-S9 (except S2 and S3).

  The control part 53 performs the process of S1 to S9 (except S2 and S3) shown in FIG. 6 about all the air conditioners.

  As described above, the control unit 53 determines, for each of the air conditioners belonging to the second group, (1) the first power consumption amount of the production line (facility) indicated by the first line identification information corresponding to the air conditioner is predetermined. The air conditioner is stopped when it is equal to or greater than the first threshold, and (2) when the first power consumption is less than the first threshold, the air conditioner is operated without reducing the air conditioning capacity.

  As a result, the air conditioners 22 to 24 and 26 to 28 belonging to the second group are heated so that the measured temperature becomes the set temperature only when the nearest production line is stopped. It is stopped when a nearby production line is in operation. As a result, when the production line is in operation and there is heat radiation from the production line, a nearby air conditioner is not heated unnecessarily. In addition, when the production line is stopped, a nearby air conditioner can be operated for heating, and a temperature decrease due to the absence of heat radiation from the production line can be effectively prevented.

  In the above description, the air conditioning / line correspondence table storage unit 52 stores information indicating the production line closest to the air conditioning apparatus as the first line identification information. However, the present invention is not limited to this, and the air conditioning-line correspondence table storage unit 52 may store information indicating a manufacturing line in the vicinity of the air conditioner as the first line identification information. For example, when the heat radiation amount when the second closest production line is operated is much larger than the heat radiation amount when the nearest production line is operated, information indicating the second closest production line is displayed. You may set as 1 line identification information. Thereby, it is possible to control the operation of the air conditioner according to the operation of a production line installed in the vicinity and having a large amount of heat radiation.

<Embodiment 2>
Another embodiment of the present invention will be described. For convenience of explanation, members having the same functions as those in the first embodiment are denoted by the same reference numerals as those in the first embodiment, and description thereof is omitted.

  In the first embodiment, when any air conditioner is stopped due to a failure, if the air conditioner adjacent to the air conditioner is stopped in the process of S7, the air conditioning capability may be extremely reduced. . Moreover, when an adjacent production line stops simultaneously, the adjacent air conditioner also stops simultaneously. Therefore, depending on the layout of the production factory, the air conditioning capability may be extremely reduced. In the present embodiment, such a problem can be solved.

  FIG. 7 is a diagram illustrating the control system 101 according to the second embodiment. As FIG. 7 shows, each air conditioner 21-28 differs from Embodiment 1 by the point connected with the wattmeters 61-68 which measure the electric energy consumed by the said air conditioner. The control device 150 of the present embodiment is different from the control device 50 of the first embodiment in that the control device 150 includes a control unit 153 instead of the control unit 53 and further includes a peripheral device information storage unit 155.

  The peripheral device information storage unit 155 includes, for each of the air conditioners 22 to 24 and 26 to 28 belonging to the second group, air conditioner identification information for identifying the air conditioner, and an air conditioner (periphery) positioned around the air conditioner. Peripheral device information in which peripheral device identification information (device identification information) for identifying the air conditioner) is associated with a second threshold value for determining the stop of the peripheral air conditioner is stored. FIG. 8 is a diagram illustrating an example of peripheral device information.

  The second threshold is smaller than the power consumption during a predetermined period (for example, 10 minutes) when the corresponding air conditioner is operating, and is smaller than the power consumption during the predetermined period when the air conditioner is stopped. A slightly larger value is set.

  The peripheral device information storage unit 155 stores peripheral device information according to user input to the input unit 54. Therefore, when the layout in the production factory is changed, the user inputs an instruction to change peripheral device information according to the new layout to the input unit 54, and the peripheral device information storage unit 155 updates the peripheral device information according to the input.

  The control unit 153 controls the air conditioners 21 to 28 according to the group, like the control unit 53 of the first embodiment. However, the control processing for the air conditioners 22 to 24 and 26 to 28 belonging to the second group is different from that of the first embodiment.

  For each of the air conditioners 22 to 24 and 26 to 28 belonging to the second group, the control unit 153 sets the first line identification information and the first threshold corresponding to the air conditioner identification information indicating the air conditioner to the air conditioning line. Read from the correspondence table. Based on the measurement data of the wattmeter connected to the production line indicated by the read first line identification information, the control unit 153 performs the first power consumption for a predetermined period (for example, a period that goes back 10 minutes from the current time). An amount is calculated and compared to a first threshold. Then, similarly to the first embodiment, the control unit determines that the production line is stopped when the calculated first power consumption is lower than the first threshold, and the calculated first power consumption is the first power consumption. If it is equal to or greater than one threshold, it is determined that the production line is operating. The control unit 153 operates the air conditioner when it is determined that the production line is stopped during the heating operation, and operates the air conditioner when it is determined that the production line is operating during the cooling operation.

  On the other hand, when it is determined that the production line is stopped during the cooling operation, or when the control unit 153 determines that the production line is operating during the heating operation, the control unit 153 performs the following processing. That is, the control unit 153 reads the peripheral device identification information and the second threshold corresponding to the air conditioner identification information indicating the air conditioner to be controlled from the peripheral device information. And the control part 153 is based on the measurement data of the wattmeter of the air conditioner shown by the read peripheral device identification information, and is the power consumption amount (henceforth, the following 10 minutes from the present time) 2nd power consumption amount) is calculated and compared with the second threshold value.

  As described above, the second threshold value is a value that is smaller than the power consumption amount during the predetermined period when the air conditioner is operating and slightly larger than the power consumption amount during the predetermined period when the air conditioner is stopped. Is set. Therefore, when the second power consumption amount is lower than the second threshold, the control unit 153 can determine that the air conditioner is stopped.

  When the second power consumption is equal to or less than the second threshold, the control unit 153 determines that the surrounding air conditioner is operating, and stops the controlled air conditioner. On the other hand, when the second power consumption amount is less than the second threshold, the control unit 153 determines that the surrounding air conditioner is stopped, and operates the controlled air conditioner without stopping. The air conditioner controlled to operate by the control unit 153 is controlled so that the measured temperature becomes the set temperature.

(Flow of control processing of air conditioner (during cooling operation))
Next, an example of the control processing of the air conditioner in the present embodiment will be described with reference to FIG. FIG. 9 is a flowchart showing a flow of control processing of the air conditioner in the present embodiment. In addition, FIG. 9 is an example in the case of air-conditioning operation of an air conditioner in summer. Since the processing from S1 to S6 is the same as that of the first embodiment (see FIG. 5), the description is omitted here.

  When the first power consumption amount is less than the first threshold value in S6 (No), the control unit 153 sets the peripheral device identification information and the second threshold value corresponding to the air conditioner identification information indicating the air conditioner to be controlled as the peripheral device information. The air conditioner located around the air conditioner to be controlled is specified (S11).

  Next, the control unit 153 calculates the second power consumption amount for a predetermined period (for example, a period 10 minutes past the current time) based on the measurement data of the power meter of the air conditioner indicated by the peripheral device identification information. To do. The control unit 153 can calculate the second power consumption amount by accumulating past measurement data of the power meters 61 to 68 corresponding to the air conditioners 21 to 28. Then, the control unit 153 compares the calculated second power consumption amount with the second threshold value read in S11 (S12).

  When the second power consumption is equal to or greater than the second threshold (Yes in S12), the control unit 153 determines that the surrounding air conditioner is operating, and stops the controlled air conditioner (S7). On the other hand, when the second power consumption is less than the second threshold (No in S12), the control unit 153 determines that the surrounding air conditioner is stopped, and proceeds to the process of S2. That is, the air conditioner to be controlled is caused to perform a normal operation according to the set temperature without lowering the air conditioning capacity.

  For example, even if the production line 15 closest to the air conditioner 26 to be controlled is stopped, if the air conditioner 27 (see FIG. 8) around the air conditioner 26 is stopped, the air conditioner 26 is operated. On the other hand, when the air conditioner 27 (see FIG. 8) around the air conditioner 26 is operating, the air conditioner 26 is stopped. Thereby, the extreme fall of the air-conditioning capability in a production factory by both the adjacent air-conditioning apparatus 26 and the air-conditioning apparatus 27 stopping can be prevented. Moreover, useless power consumption can be prevented by stopping the air conditioner 26 when the surrounding air conditioner 27 is operating.

  Control part 153 performs processing of S1 to S12 shown in Drawing 9 about all the air conditioners 21-28.

  As described above, the control unit 153 determines, for each of the air conditioners belonging to the second group, (1) the first power consumption amount of the production line indicated by the first line identification information corresponding to the air conditioner is less than the first threshold value. And when the second power consumption of the air conditioner indicated by the peripheral device identification information corresponding to the air conditioner is equal to or greater than a predetermined second threshold, the air conditioner is stopped, and (2) the first When the power consumption is greater than or equal to the first threshold or the second power consumption is less than the second threshold, the air conditioner is operated without reducing the air conditioning capacity.

  As a result, the air conditioners 22 to 24 and 26 to 28 belonging to the second group are only in the cooling operation when the nearest production line is stopped and the surrounding air conditioners are in operation. Is stopped. As a result, it is possible to prevent an extreme decrease in the air conditioning capacity in the production factory.

(Flow of control processing of air conditioner (during heating operation))
Next, an example of the control processing of the air conditioner in the present embodiment will be described with reference to FIG. In addition, FIG. 10 is an example in the case of heating operation of the air conditioners 21 to 28 in winter.

  Since the processes of S1, S4 to 6, S8, and S9 are the same as those of the first embodiment shown in FIG. 6, the description thereof is omitted here.

  When the first power consumption amount is greater than or equal to the first threshold in S6 (Yes), the control unit 153 sets the peripheral device identification information and the second threshold corresponding to the air conditioner identification information indicating the air conditioner to be controlled as the peripheral device information. The air conditioner located around the air conditioner to be controlled is specified (S11).

  Next, the control unit 153 calculates the second power consumption amount for a predetermined period (for example, a period 10 minutes past the current time) based on the measurement data of the power meter of the air conditioner indicated by the peripheral device identification information. To do. The control unit 153 can calculate the second power consumption amount by accumulating past measurement data of the power meters 61 to 68 corresponding to the air conditioners 21 to 28. Then, the control unit 153 compares the calculated second power consumption amount with the second threshold value read in S11 (S12).

  When the second power consumption is equal to or greater than the second threshold (Yes in S12), the control unit 153 determines that the surrounding air conditioner is operating, and stops the controlled air conditioner (S7). On the other hand, when the second power consumption is less than the second threshold (No in S12), the control unit 153 determines that the surrounding air conditioner is stopped, and proceeds to the process of S2. That is, the air conditioner to be controlled is operated according to the normal set temperature without reducing the air conditioning capacity.

  Control part 153 performs processing of S1 to S12 shown in Drawing 10 about all the air conditioners 21-28.

  As described above, the control unit 153 has (1) the first power consumption of the production line indicated by the first line identification information corresponding to the air conditioner for the air conditioners belonging to the second group. If the second power consumption amount of the air conditioner indicated by the peripheral device identification information corresponding to the air conditioner is equal to or greater than the predetermined second threshold, the air conditioner is stopped, and (2) When the first power consumption amount is less than the first threshold value or the second power consumption amount is less than the second threshold value, the air conditioner is operated without reducing the air conditioning capability.

  As a result, the air conditioners 22 to 24 and 26 to 28 belonging to the second group are heated only when the nearest production line is in operation and the surrounding air conditioners are in operation. Is stopped. As a result, it is possible to prevent an extreme decrease in the air conditioning capacity in the production factory.

<Embodiment 3>
Still another embodiment of the present invention will be described. For convenience of explanation, members having the same functions as those in the first embodiment are denoted by the same reference numerals as those in the first embodiment, and description thereof is omitted.

  Depending on the production plant, the amount of heat released during operation in a plurality of production lines may differ. For example, a production line may include a heating device, but a surrounding production line may not include a heating device. Such an air conditioner installed in the vicinity of a production line that does not include a heating device plays a role of preventing a temperature rise due to heat radiation from the production line including the heating device around the production line. Therefore, if the air conditioner in the vicinity thereof is stopped in synchronization with the stop of the production line that does not include the heating device as in the first embodiment, the air conditioning capability in the production factory may be extremely reduced. There is. In the present embodiment, such a problem can be solved.

  FIG. 11 is a diagram illustrating a control system 201 according to the present embodiment. As shown in FIG. 11, the control device 250 of the present embodiment includes a control unit 253 instead of the control unit 53, and an air conditioning-line correspondence table storage unit 252 instead of the air conditioning-line correspondence table storage unit 52. This differs from the control device 50 of the first embodiment.

  The air conditioner-line correspondence table storage unit 252 is installed at the closest position of the air conditioner and the air conditioner identification information indicating the air conditioner for each of the air conditioners 22 to 24 and 26 to 28 belonging to the second group. Peripheral manufacturing which is the first line identification information for identifying the production line, the first threshold value for determining the stop of the production line, and the production line installed around the production line and selected as the line to be monitored An air conditioning-line correspondence table is stored in which second line identification information for identifying a line is associated with a third threshold value for determining the stop of a peripheral production line. FIG. 12 is a diagram illustrating an example of the air-conditioning / line correspondence table stored in the air-conditioning / line correspondence table storage unit 252.

  Note that the third threshold value is smaller than the power consumption during a predetermined period (for example, 10 minutes) when the corresponding peripheral manufacturing line is operating (operating), and is the predetermined value when the peripheral manufacturing line is stopped. A value slightly larger than the power consumption during the period is set.

  As the peripheral production line, for example, a production line having a large heat dissipation amount including a heating device is appropriately selected. Note that it is not necessary to set peripheral manufacturing lines for all air conditioners, and it is only necessary to set monitored production lines for some air conditioners according to the layout in the production factory. For example, as illustrated in FIG. 12, the second line identification information is not set for the air conditioner 27. This is because the production lines 15 and 17 around the production line 16 closest to the air conditioner 27 do not include a heating device, and the amount of heat radiation is small, so that monitoring is not necessary. Further, like the air conditioner 23, a plurality of second line identification information and third threshold values may be set for one air conditioner.

  The air conditioning-line correspondence table storage unit 252 stores an air conditioning-line correspondence table corresponding to a user input to the input unit 54. Therefore, when the layout in the production factory 10 is changed, the user inputs an instruction to change the first line identification information and the second line identification information corresponding to the new layout to the input unit 54, and the air conditioning-line correspondence table storage unit Reference numeral 252 updates the air conditioning-line correspondence table according to the input.

  The control part 253 controls each air conditioner 21-28 according to a group similarly to the control part 53 of Embodiment 1. FIG. However, the control processing for the air conditioners 22 to 24 and 26 to 28 belonging to the second group is different from that of the first embodiment.

  For each of the air conditioners 22 to 24 and 26 to 28 belonging to the second group, the control unit 253 sets the first line identification information and the first threshold value corresponding to the air conditioner identification information indicating the air conditioner to the air conditioning line. Read from the correspondence table. Based on the measurement data of the wattmeter connected to the production line indicated by the read first line identification information, the control unit 253 performs the first power consumption for a predetermined period (for example, a period that goes back 10 minutes from the current time). An amount is calculated and compared to a first threshold. Then, similarly to the first embodiment, the control unit 253 determines that the production line is stopped when the calculated first power consumption is lower than the first threshold, and the calculated first power consumption is If it is equal to or greater than the first threshold, it is determined that the production line is operating. The control unit 253 operates the air conditioner when it is determined that the production line is stopped during the heating operation, and operates the air conditioner when it is determined that the production line is operating during the cooling operation.

  On the other hand, when it is determined that the production line is stopped during the cooling operation, or when the control unit 253 determines that the production line is operating during the heating operation, the control unit 253 performs the following processing. That is, the control unit 253 reads out the second line identification information and the third threshold corresponding to the air conditioner to be controlled from the air conditioning-line correspondence table, and measures the wattmeter of the production line indicated by the read second line identification information. Based on the data, a power consumption amount (hereinafter, referred to as a third power consumption amount) for a predetermined period (for example, a period 10 minutes past the current time) is calculated and compared with a third threshold value.

  As described above, the third threshold value is smaller than the power consumption amount in a predetermined period when the corresponding peripheral manufacturing line is operating (operating), and in the predetermined period when the peripheral manufacturing line is stopped. A value slightly larger than the power consumption is set. Therefore, when the calculated third power consumption is lower than the third threshold, the control unit 253 can determine that the peripheral manufacturing line is stopped. When the third power consumption is equal to or less than the third threshold, the control unit 253 determines that the peripheral production line is in operation and operates the controlled air conditioner without stopping it. On the other hand, when the third power consumption amount is less than the third threshold, the control unit 253 determines that the peripheral manufacturing line is stopped, and stops the controlled air conditioner. The air conditioner controlled to operate by the control unit 253 is controlled so that the measured temperature becomes the set temperature.

(Flow of control processing of air conditioner (during cooling operation))
Next, an example of the control processing of the air conditioner in the present embodiment will be described with reference to FIG. FIG. 13 is a flowchart showing a flow of control processing of the air conditioner in the present embodiment. FIG. 13 is an example of a case where the air conditioner is operated for cooling in summer. Since the processing from S1 to S6 is the same as that of the first embodiment (see FIG. 5), the description is omitted here.

  When the first power consumption amount is less than the first threshold value in S6 (No), the control unit 253 sets the second line identification information and the third threshold value corresponding to the air conditioner identification information indicating the air conditioner to be controlled. Is determined based on the air conditioning-line correspondence table (S13).

  When the second line identification information and the third threshold corresponding to the air conditioner identification information are not set (No in S13), the control unit 253 determines that there is no peripheral production line to be monitored, and controls the air conditioning to be controlled. The apparatus is stopped (S7).

  When the second line identification information and the third threshold corresponding to the air conditioner identification information are set (Yes in S13), the control unit 253 reads out the second line identification information and the third threshold. The read second line identification information indicates the peripheral production line to be monitored. Then, the control unit 253 calculates the third power consumption amount for a predetermined period (for example, a period 10 minutes past the current time) based on the measurement data of the power meter of the production line indicated by the second line identification information. To do. The control unit 253 compares the calculated third power consumption amount with the third threshold value (S14).

  When the third power consumption is less than the third threshold (Yes in S14), the control unit 253 determines that the peripheral production line to be monitored is stopped, and stops the controlled air conditioner (S7). . On the other hand, when the third power consumption is greater than or equal to the third threshold (No in S14), the control unit 253 determines that the peripheral manufacturing line to be monitored is operating, and proceeds to the process of S2. That is, the air conditioner to be controlled is operated according to the normal set temperature without reducing the air conditioning capacity.

  For example, even if the nearest production line 15 is stopped with respect to the air conditioner 26 to be controlled, if the peripheral production line 16 (see FIGS. 1 and 12) is operating, the air conditioner 26 is operated. On the other hand, if the peripheral production line 16 is also stopped, the air conditioner 26 is stopped. Thereby, when the production line 16 is operated and dissipates heat, the air conditioner 26 is operated, so that an extreme decrease in the air conditioning capacity in the production factory can be prevented. Further, when the production line 16 is stopped, useless power consumption can be prevented by stopping the air conditioner 26.

  Also, as shown in FIG. 12, the air conditioner 23 in which a plurality of peripheral production lines are set may be processed as follows in S14. The control unit 253 reads out the combination of the second line identification information and the third threshold value for each peripheral production line. And the 3rd power consumption calculated | required from the measurement data of the wattmeter of the manufacturing line shown by 2nd line identification information for every combination is compared with a 3rd threshold value. In all combinations, if the third power consumption is less than the third threshold, it is determined Yes in S14, otherwise it is determined No in S14. Alternatively, when the third power consumption is less than the third threshold in at least one combination, it may be determined as Yes in S14, and may be determined as No in S14 in other cases. For example, for the air conditioner 23 to be controlled, the third power consumption of the production line 11 is less than the third threshold (1 kW), and the third power consumption of the production line 13 is less than the third threshold (1 kW). If so, the process proceeds to S7. Or you may transfer to the process of S7, when the 3rd power consumption of at least one of the production line 11 and the production line 12 is less than a 3rd threshold value.

  Control part 253 performs processing of S1 to S14 shown in Drawing 13 about all the air conditioners 21-28.

  As described above, the control unit 253, for each of the air conditioners belonging to the second group, (1) the first power consumption of the production line indicated by the first line identification information corresponding to the air conditioner is a predetermined first. When the third power consumption of the peripheral production line indicated by the second line identification information corresponding to the air conditioner is less than the threshold value and less than the predetermined third threshold value, the air conditioner is stopped, 2) When the first power consumption is greater than or equal to the first threshold or the third power consumption is greater than or equal to the third threshold, the air conditioner is operated without reducing the air conditioning capacity.

  Thereby, as for the air conditioners 22-24, 26-28 belonging to the second group, only when the nearest production line is stopped and the peripheral production line to be monitored is also stopped, Stopped. As a result, it is possible to prevent an extreme decrease in the air conditioning capacity in the production factory.

Is determined based on the air conditioning-line correspondence table (S13).

  When the second line identification information and the third threshold corresponding to the air conditioner identification information are not set (No in S13), the control unit 253 determines that there is no peripheral production line to be monitored, and controls the air conditioning to be controlled. The apparatus is stopped (S7).

  When the second line identification information and the third threshold corresponding to the air conditioner identification information are set (Yes in S13), the control unit 253 reads out the second line identification information and the third threshold. The read second line identification information indicates the peripheral production line to be monitored. Then, the control unit 253 calculates the third power consumption amount for a predetermined period (for example, a period 10 minutes past the current time) based on the measurement data of the power meter of the production line indicated by the second line identification information. To do. The control unit 253 compares the calculated third power consumption amount with the third threshold value (S14).

  When the third power consumption is less than the third threshold (Yes in S14), the control unit 253 determines that the peripheral production line to be monitored is stopped, and proceeds to the process of S8. That is, the air conditioner to be controlled is operated according to the normal set temperature without reducing the air conditioning capacity. On the other hand, when the third power consumption is equal to or greater than the third threshold (No in S14), the control unit 253 determines that the peripheral production line to be monitored is operating and stops the controlled air conditioner ( S7).

  Control part 253 performs processing of S1 to S14 shown in Drawing 14 about all the air conditioners 21-28.

  As described above, the control unit 253, for each of the air conditioners belonging to the second group, (1) the first power consumption of the production line indicated by the first line identification information corresponding to the air conditioner is a predetermined first. If the third power consumption of the peripheral manufacturing line indicated by the second line identification information corresponding to the air conditioner is equal to or greater than a predetermined third threshold, the air conditioner is stopped, 2) When the first power consumption is less than the first threshold or the third power consumption is less than the third threshold, the air conditioner is operated without reducing the air conditioning capacity.

  As a result, the air conditioners 22 to 24 and 26 to 28 belonging to the second group are only operated when the nearest production line is in operation and the peripheral production line to be monitored is also in operation. Stopped. As a result, it is possible to prevent an extreme decrease in the air conditioning capacity in the production factory.

<Modification>
In the above description, the control units 53, 153, and 253 stop the air conditioner to be controlled in step S7. However, in the step of S7, the control units 53, 153, and 253 may perform control to reduce the air conditioning capability of the air conditioner to be controlled. For example, when connected to two outdoor units such as the air conditioner 24 and the air conditioner 28, the operation of the air conditioners 24 and 28 is performed by reducing the air conditioning capability by stopping only one of the outdoor units. You may let them.

  Further, when the air conditioner 24 is connected to two outdoor units like the air conditioner 24 and the air conditioner 28 and the air conditioning capacity is reduced by stopping one of the outdoor units in S7, the following processing may be performed. . That is, in S7, it is determined whether one of the two outdoor units has already stopped. And when one has already stopped, since the air-conditioning capability has already fallen, the other one is maintained as it is without stopping. On the other hand, when both of the two outdoor units are operating, one of them is stopped to reduce the air conditioning capacity.

  According to said structure, about the air conditioner which belongs to a 2nd group, a driving | operation is controlled according to the operating state of the said installation. The amount of heat released from the equipment depends on the operating state of the equipment. Therefore, by operating the second group of air conditioners according to the operating state of the facility, the second group of air conditioners can be operated according to the heat radiation amount of the facility.
