(Knowledge, etc. on which this disclosure is based)
At the time when the inventors came up with the present disclosure, there was a technique for detecting the outside air temperature of a building in which an air conditioner is installed and changing the set temperature of the air conditioner according to the change in the outside air temperature.
However, since the outside air temperature is only one of the factors that affect the comfort of the space to be conditioned, even if the set temperature of the air conditioner is changed based on the outside temperature, the comfort of the space to be conditioned may not be ensured. highly sexual. Therefore, the inventors found a problem that the set temperature of the air conditioner is often changed in order to ensure comfort in the space to be conditioned, and it is difficult to suppress the energy consumption of the air conditioner. In order to solve the problem, the subject of the present disclosure has been constructed. In addition, the inventors have also discovered that when the set temperature of the air conditioner is changed, there is a general tendency to seek excessive comfort, and the energy consumption of the air conditioner tends to increase. , came to constitute the subject matter of the present disclosure in order to solve the problem. Note that excessively seeking comfort means, for example, setting the set temperature unnecessarily low during cooling operation and setting the set temperature unnecessarily high during heating operation.
Accordingly, the present disclosure provides a management system capable of maintaining the comfort of the space to be conditioned and suppressing the energy consumption of the air conditioner.

Hereinafter, embodiments will be described in detail with reference to the drawings. However, more detailed description than necessary may be omitted. For example, detailed descriptions of well-known matters or redundant descriptions of substantially the same configurations may be omitted.
It should be noted that the accompanying drawings and the following description are provided to allow those skilled in the art to fully understand the present disclosure and are not intended to limit the claimed subject matter thereby.

The air conditioner 10A includes a control device 11, an outdoor unit 12, an indoor unit 13, an operation unit 14, a communication device 15, and an outside air temperature sensor 18. Air conditioners 10B, 10C, 10D and other air conditioners 10 are similarly configured. Note that the configuration of FIG. 1 is an example, and there is no limit to the number of outdoor units 12 and indoor units 13 provided in the air conditioner 10A. For example, the air conditioner 10A may be configured to air-condition a plurality of spaces in the facility 1A using a plurality of indoor units 13 .

Although not shown, the outdoor unit 12 includes a compressor, various valves such as a four-way valve and an on-off valve, an outdoor heat exchanger, and a refrigerant circuit connecting them. The indoor unit 13 includes various valves such as an expansion valve and an on-off valve, an indoor heat exchanger, and a refrigerant circuit connecting these. The refrigerant circuit of the outdoor unit 12 and the refrigerant circuit of the indoor unit 13 are connected.

The control device 11 is connected to the outdoor unit 12, the indoor unit 13, the operating unit 14, and the outdoor temperature sensor 18. The control device 11 controls the operation of the compressor provided in the outdoor unit 12 and the opening and closing of the valves provided in the outdoor unit 12 and the indoor unit 13 so that the temperature of the space to be conditioned reaches the set target temperature. Then, the air conditioner 10 is operated. The control device 11 includes, for example, a memory and a processor, and the processor controls the air conditioner 10A according to data stored in the memory by executing a program stored in the memory. The processor of controller 11 is, for example, a microcontroller integrated with memory. The control device 11 corresponds to an example of a control unit in the present disclosure.

An outside air temperature sensor 18 is connected to the control device 11 . It is a temperature sensor that detects the air temperature, and the detection method of the outside air temperature sensor 18 is not limited. The outside air temperature sensor 18 is installed in the outdoor unit 12, for example.

The target temperature set in the air conditioner 10A will be referred to as the set temperature in the following description.
The operation unit 14 has switches and the like for operating the air conditioner 10A. The operation unit 14 is, for example, a controller installed in the facility 1A. By operating the operation unit 14, it is possible to instruct the control device 11 to start and stop the operation of the air conditioner 10A, and to change the set temperature. The control device 11 performs operations such as starting and stopping the operation of the air conditioner 10A and changing the set temperature according to the operation of the operation unit 14 . In the following description, among the operations performed by the operation unit 14, an operation for changing the set temperature of the air conditioner 10 is called a temperature change operation.

The communication device 15 is a device that communicates with the management server 100 via the communication network N. The communication device 15 is a device that connects to a communication network N via a public line network, a WAN (Wide Area Network), a LAN (Local Area Network), an IP communication line network, or the like, and performs data communication. The communication device 15 may be a wireless communication device that connects to the communication network N by performing wireless communication such as a cellular communication system or Wi-Fi. The communication device 15 receives setting data SD described later from the management server 100 and transmits operation data RD described later to the management server 100 . The communication device 15 corresponds to an example of a transmitter in the present disclosure.

The air conditioners 10B, 10C, 10D and other air conditioners 10 included in the management system 1000 have the same configuration as the air conditioner 10A. These air conditioners 10 are provided with a control device 11 . The control device 11 operates the outdoor unit 12 and the indoor unit 13 according to the operation of the operation unit 14, thereby air-conditioning the space to be conditioned.

The management server 100 transmits the setting data SD to the air conditioners 10 connected to the management server 100. All the air conditioners 10 managed by the management server 100 share the operation related to the setting data SD and the operation data RD, which will be described later.

The setting data SD includes the temperature setting of the air conditioner 10, and more specifically, the temperature setting during the cooling operation and the temperature setting during the heating operation. The control device 11 receives the setting data SD through the communication device 15 and operates the air conditioner 10 at the set temperature designated by the received setting data SD.

The setting data SD may include information regarding the temperature change operation. Specifically, the setting data SD may include information as to whether or not the temperature changing operation is permitted. The setting data SD may include information instructing to return the setting temperature to the temperature before the change when the control device 11 changes the setting temperature according to the temperature change operation. In this case, the setting data SD may include information specifying a time limit from when the set temperature is changed until the set temperature is returned to the temperature before the change.

The control device 11 determines whether or not to permit the temperature change operation according to the setting data SD. When the setting data SD designates that the temperature changing operation is permitted, the control device 11 changes the set temperature according to the temperature changing operation.

Furthermore, the management server 100 transmits to the air conditioner 10 a control parameter CP for determining the set temperature of the air conditioner 10 based on the outside air temperature detected by the outside air temperature sensor 18 by the control device 11 . The control device 11 autonomously determines the set temperature of the air conditioner 10 based on the control parameter CP received by the communication device 15 . The control parameter CP will be described later.

In this embodiment, in the facility 1, it is possible to start and stop the operation of the air conditioner 10 and switch between cooling and heating by operating the operation unit 14. The set temperature of the air conditioner 10 is the temperature specified by the set data SD or the temperature determined by the control device 11 according to the control parameter CP. Further, in the air conditioner 10, it is allowed to change the set temperature according to the operation of the temperature change operation. When receiving a temperature change operation, the control device 11 changes the set temperature in accordance with the temperature change operation, and after a predetermined time limit has elapsed since the set temperature was changed, the set temperature is returned to the temperature before the change. Let

The control device 11 generates operation data RD indicating that the temperature change operation has been accepted, and transmits the data to the management server 100 via the communication device 15 . As shown in FIG. 1, the operation data RD includes, for example, at least one of a facility ID and an air conditioner ID. The facility ID is identification information that identifies each of the facilities 1A, 1B, 1C, 1D and other facilities 1. FIG. The air conditioner ID is identification information that identifies each of the air conditioners 10A, 10B, 10C, 10D, and other air conditioners 10 .

The operation data RD includes the date and time when the temperature change operation was performed and the outside air temperature when the operation was performed. The operation data RD may include the set temperature after change.
The management server 100 receives and stores the operation data RD transmitted by the air conditioner 10 . Based on the operation data RD, the management server 100 determines the control parameter CP used in the process of determining the set temperature of the air conditioner 10 corresponding to the outside air temperature. The management server 100 determines the control parameter CP for each facility 1 or each air conditioner 10 .

From the viewpoint of energy saving, it is not recommended to prioritize the comfort of the people in the space to be conditioned when setting the temperature setting of the air conditioner 10 . Specifically, for example, if a person in the space to be conditioned can freely operate the operation unit 14 to change the set temperature, the energy consumption of the air conditioning apparatus 10 is not taken into account, so it is thought that the energy consumption will increase. be done. Therefore, it is conceivable to limit the set temperature of the air conditioner from the viewpoint of saving energy. For example, the Ministry of Economy, Trade and Industry recommends setting the air conditioning temperature to 28° C. during cooling operation in summer and 20° C. during heating operation in winter. However, when these temperatures are used as the set temperatures of the air conditioner 10, the comfort of the space to be conditioned may decrease, and it is a problem to achieve both the comfort of the space to be conditioned and energy saving.

The indoor temperature of the space to be conditioned is affected by the outdoor temperature. Furthermore, the position and shape of the building, the position of the space to be harmonized in the building, the sunlight in the space to be harmonized, etc. affect the indoor temperature of the space to be harmonized. If the set temperature of the air conditioner 10 is determined based only on the outside air temperature without considering these influences, the possibility that the comfort of the space to be conditioned by the air conditioner 10 will be reduced cannot be ruled out.

Therefore, the management system 1000 of this embodiment makes it possible to determine the set temperature of the air conditioner 10 according to the characteristics of the space to be conditioned. That is, the management server 100 generates, for each air conditioner 10, a control parameter CP for determining the set temperature of the air conditioner 10 based on the outside air temperature, and transmits the control parameter CP to the air conditioner 10. FIG. The air conditioner 10 determines the set temperature from the outside air temperature detected by the outside air temperature sensor 18 according to the control parameter CP transmitted by the management server 100 . The control parameters CP generated by the management server 100 are adapted to the conditions of each air conditioner 10 . Therefore, in each air conditioner 10, energy consumption can be suppressed while maintaining the comfort of the space to be conditioned.

[2. Management server configuration]
FIG. 2 is a block diagram of the management server 100. As shown in FIG.
The management server 100 has a control unit 110 and a server communication device 150 .

The control unit 110 includes a processor 120 and a memory 130. The processor 120 is composed of a CPU (Central Processing Unit), an MPU (Micro-Processing Unit), and other arithmetic processing units. The memory 130 is a storage device that stores programs and data executed by the processor 120 in a non-volatile manner. Memory 130 may comprise magnetic storage devices, semiconductor storage devices, or other types of non-volatile storage devices. Specifically, the memory 130 has a HDD (Hard Disk Drive), a flash ROM (Read Only Memory), an SSD (Solid State Drive) composed of a flash ROM, and the like. The memory 130 may include a RAM (Random Access Memory) forming a work area of the processor 120 . Processor 120 is an example of a computer in this disclosure.

Memory 130 stores a control program 131 executed by processor 120 . The control program 131 corresponds to an example of a program in this disclosure.
The memory 130 stores temperature setting data 132 , history DB (database) 133 , control parameters CP, and power consumption DB 135 . These are data that are processed or generated by processor 120 .

The temperature setting data 132 is data of the temperature setting of the air conditioner 10 . The temperature setting data 132 includes the set temperature data included in the setting data SD. The temperature setting data 132 may be data of a setting temperature common to all air conditioners 10 . Also, the temperature setting data 132 may include data of temperature setting that differs for each air conditioner 10 or each facility 1 .

The history DB 133 includes history of temperature change operations in the air conditioner 10 .
FIG. 2 shows a configuration example of the history DB 133. As shown in FIG. The history DB 133 stores data of temperature changing operations performed in the air conditioner 10 . The data stored in the history DB 133 is, for example, record format data in which air conditioner IDs and setting change histories are associated with each other. This configuration is an example, and in the records stored in the history DB 133, the facility ID may be associated with the setting change history instead of the air conditioner ID.

One record stored in the history DB 133 corresponds to one temperature change operation in one air conditioner 10. The record of the history DB 133 includes the setting change date and time, the type of operation, the outside air temperature, the set temperature, and the set temperature after the change. The setting change date and time is the date and time when the set temperature is changed according to the operation of the operation unit 14 and is substantially the same as the date and time when the control device 11 accepts the operation of the operation unit 14 . The operation type indicates the operating state of the air conditioner 10 when the temperature changing operation is performed. In this embodiment, the operation type is either cooling or heating. The outside air temperature is the outside air temperature when the temperature changing operation is performed. The set temperature is the set temperature of the air conditioner 10 when the temperature change operation is performed. This set temperature is the temperature instructed by the management server 100 to the air conditioner 10 by means of the setting data SD. The set temperature after change is the set temperature of the air conditioner 10 that has been changed as a result of the temperature change operation.

In this way, the history DB 133 includes the history of temperature change operations for each air conditioner 10 in association with the air conditioner ID. In the example of FIG. 2, only the records in which the operation type is cooling are illustrated, but the history DB 133 can store data received by the management server 100 throughout the year.

The control parameter CP is data for the control device 11 to autonomously determine the set temperature of the air conditioner 10 . The control parameter CP may be data processed by the control device 11 . Also, the control parameter CP may be a program that defines the arithmetic processing executed by the control device 11 or an arithmetic expression for the arithmetic processing executed by the control device 11 . Further, the control parameter CP may include coefficients and constants used in arithmetic processing executed by the control device 11 . The control parameter CP includes at least the set temperature of the air conditioner 10 corresponding to the outside air temperature or data for determining the set temperature.

The power consumption DB 135 stores data indicating the power consumption of the air conditioner 10 . The power consumption DB 135 stores data indicating the power consumption in association with the air conditioner ID of the air conditioner 10, for example. The data stored in the power consumption DB 135 is, for example, power consumption data for each day. Data delimiters can be changed as appropriate, and the data stored in the power consumption DB 135 may be power consumption data for each facility.

The processor 120 controls each part of the management server 100 by executing the control program 131 . The processor 120 includes an acquisition unit 121, a determination unit 122, a setting unit 123, and a processing unit 124 as functional units. Each of these functional units is realized by the cooperation of software and hardware when the processor 120 executes the control program 131 .

A server communication device 150 is connected to the control unit 110 . The server communication device 150 is a communication device connected to the communication network N. FIG. The server communication device 150 includes, for example, a connector for connecting a communication cable, and an interface circuit for inputting/outputting signals through the connector. Further, for example, the server communication device 150 may be a wireless communication device that includes an antenna and a wireless circuit and connects to the communication network N via a wireless communication line.

The acquisition unit 121 communicates with the air conditioner 10 through the server communication device 150 and receives the operation data RD from the air conditioner 10 . The acquisition unit 121 adds data to the history DB 133 based on the operation data RD and updates the history DB 133 .

The acquisition unit 121 also communicates with the air conditioner 10 through the server communication device 150 and receives data on power consumption from the air conditioner 10 . Acquisition unit 121 adds data to power consumption DB 135 based on the received data, and updates power consumption DB 135 .

The determination unit 122 determines whether the data acquired by the acquisition unit 121 satisfies the conditions necessary for the process of determining the control parameter CP. For example, the determination unit 122 determines whether or not the number of data acquired by the acquisition unit 121 is equal to or greater than the number required for the process of determining the control parameter CP.

The setting unit 123 sets the preset temperature of the air conditioner 10 . For example, the setting unit 123 generates setting data SD based on the temperature setting data 132 and transmits the setting data SD to the air conditioner 10 by the server communication device 150 .

The processing unit 124 generates the control parameter CP based on the data stored in the history DB 133. Generating the control parameter CP is synonymous with determining the control parameter CP. The processing unit 124 , for example, generates control parameters CP for each air conditioner 10 and stores them in the memory 130 . The control parameter CP stored in the memory 130 is transmitted to the air conditioner 10 by the temperature setting data 132. FIG.

The processing unit 124 generates comparison data that compares the case where the air conditioner 10 operates not based on the control parameters CP and the case where the air conditioner 10 operates according to the control parameters CP. The processing unit 124 generates comparison data in which power consumptions are compared based on data stored in the power consumption DB 135, for example. In this case, the comparison data is the power consumption when the air conditioner 10 is operated at the set temperature specified by the setting data SD, and the power consumption when the set temperature is determined according to the control parameter CP. are data for comparison. The comparison data is, for example, power consumption when the air conditioner 10 is operated at the set temperature specified by the setting data SD and power consumption when the set temperature is determined according to the control parameter CP. , including graphs and tables for visual comparison. The comparison data is transmitted to one or both of the terminal device 5 and the mobile terminal device 7 and displayed on the display 51 or the display 71 .

[3. Operation of management system]
FIG. 3 is a flow chart showing the operation of the management system 1000. As shown in FIG.
In FIG. 3, the operations of steps SA1-SA2, SA4-SA9, SA11, SA13-SA15 are executed by the management server 100. FIG. The operations of steps SA3, SA10 and SA12 are executed by the management server 100 and the air conditioner 10. FIG.

The processing unit 124 determines control parameter generation conditions (step SA1). The processing unit 124 generates a control parameter CP corresponding to each air conditioner 10 managed by the management server 100 . The processing unit 124 also generates a control parameter CP for the heating operation and a control parameter CP for the cooling operation of the air conditioner 10 . Therefore, in step SA1, the processing unit 124 determines a control parameter generation condition, which is a condition regarding generation of the control parameter CP. Specifically, the control parameter generation condition includes the air conditioner ID of the air conditioner 10 to which the control parameter CP is applied. The control parameter generation condition may include a driving type to which the control parameter CP is applied. The operation type is heating or cooling.

The determination in step SA1 identifies the air conditioner 10 for which the control parameter CP is to be generated. The management server 100 can execute the operations of FIG. 3 in parallel for a plurality of air conditioners 10 . In the following description, an example will be described in which it is determined in step SA1 that the target for generating the control parameter CP is the air conditioner 10A.

The setting unit 123 transmits setting data SD including the temperature setting to the air conditioner 10A for which the control parameter CP is to be generated (step SA2).
Acquisition unit 121 executes an operation data acquisition process on air conditioner 10A (step SA3). The operation data acquisition process is a process of acquiring operation data RD from the air conditioner 10A and accumulating it in the history DB 133 .

FIG. 4 is a sequence diagram showing the operation data acquisition process executed in step SA3 of FIG. In FIG. 4, steps SB1 to SB4 indicate operations of the management server 100, and steps SC1 to SC9 indicate operations of the air conditioner 10. FIG. Here, an example in which the air conditioner 10A executes steps SC1 to SC9 will be described.

The control device 11 receives the setting data SD transmitted by the management server 100, and starts operating the air conditioner 10A according to the setting data SD (step SC1). During operation of the air conditioner 10A, the control device 11 determines whether or not there is a temperature change operation by the operation unit 14 (step SC2). When determining that the temperature change operation has not been performed (step SC2; NO), the control device 11 proceeds to step SC7, which will be described later.

When the controller 11 determines that the temperature change operation has been performed (step SC2; YES), it changes the set temperature of the air conditioner 10A according to the temperature change operation (step SC3). The control device 11 generates operation data RD including the content of the temperature change operation by the operation unit 14 (step SC4). The control device 11 determines whether or not the return timing for returning the set temperature has been reached (step SC5), and if the return timing has not been reached (step SC5; NO), the operation of the air conditioner 10A is continued. wait while

The return timing is determined, for example, by the time limit after the set temperature is changed according to the temperature change operation. The time limit is designated, for example, by setting data SD. For example, if the time limit is 30 minutes, the control device 11 determines that the return timing has been reached 30 minutes after changing the set temperature in step SC3 (step SC5). The return timing may be determined based on time. For example, the control device 11 may set the first hour on the hour after changing the set temperature as the return timing, or may set the second hour on the hour after changing the set temperature as the return timing. In this case as well, the return timing is specified by the setting data SD. This configuration can be applied when the control device 11 has an RTC (Real Time Clock) and can acquire the current time.

When the controller 11 determines that the return timing has been reached (step SC5; YES), the set temperature of the air conditioner 10A is returned to the set temperature before the change (step SC6). The set temperature before change is the set temperature before the set temperature is changed in step SC3. After that, the controller 11 proceeds to step SC6.

At step SC6, the control device 11 determines whether or not the transmission timing for transmitting the operation data RD has arrived (step SC7). If it is determined that the transmission timing has not been reached (step SC7; NO), the control device 11 returns to step SC2. If it is determined that the transmission timing has been reached (step SC7; YES), the control device 11 transmits the operation data RD to the management server 100 through the communication device 15 (step SC8).

The transmission timing is specified by the setting data SD or set in the control device 11 in advance. The transmission timing may be one or more times of the day. In this case, the control device 11 transmits the operation data RD once or multiple times a day. The control device 11 generates the operation data RD corresponding to the temperature change operation performed before reaching the transmission timing, and transmits the operation data RD to the management server 100 . The control device 11 may generate operation data RD including data relating to a plurality of temperature change operations, or may collectively transmit a plurality of operation data RD corresponding to one temperature change operation to the management server 100. good too. The transmission timing may be once in a plurality of days, or may be in a longer cycle. Also, the transmission timing may be determined by the number of temperature change operations. For example, the transmission timing may be reached every time the temperature changing operation is performed a set number of times.

The acquisition unit 121 receives the operation data RD transmitted by the air conditioner 10A (step SB1). Acquisition unit 121 stores information included in received operation data RD in history DB 133 in association with the air conditioner ID of air conditioner 10A, and updates history DB 133 (step SB2).

Furthermore, the control device 11 transmits data indicating the power consumption of the air conditioner 10A to the management server 100 (step SC9). Acquisition unit 121 receives the power consumption data transmitted by air conditioner 10A (step SB3). The acquisition unit 121 associates the received power consumption data with the air conditioner ID of the air conditioner 10A, stores the data in the power consumption DB 135, and updates the power consumption DB 135 (step SB4).

Unless the management server 100 gives an instruction, the air conditioner 10A operates according to the operation to start operation, the operation to end operation, and the temperature change operation by the operation unit 14, and repeats steps SC1 to SC10.

In the operation example of FIG. 4, the frequency at which the control device 11 transmits the operation data RD matches the frequency at which the power consumption data is transmitted. This is just an example, and for example, the timing of transmitting the power consumption data may be different from the timing of transmitting the operation data RD. For example, the control device 11 may transmit daily power consumption data of the air conditioner 10A to the management server 100 once a week or once a month in step SC9.

Further, the control device 11 may be configured to generate the operation data RD only for a temperature change operation instructing a temperature change in a specific direction among the temperature change operations. The specific direction is, for example, a direction that enhances the comfort of the space to be conditioned by the air conditioner 10A. In this case, the temperature change operation for instructing a temperature change in a specific direction is specifically a temperature change operation for changing the set temperature to a lower temperature during the cooling operation of the air conditioner 10A, and during the heating operation. is a temperature change operation that changes the set temperature to a higher temperature. Also, the specific direction may be a direction in which the power consumption of the air conditioner 10A increases.

In this case, if the control device 11 determines that the temperature change operation has been performed (step SC2; YES), it changes the set temperature of the air conditioner 10A in step SC3 regardless of the direction of the temperature change. After that, the control device 11 generates the operation data RD in step SC4 if the temperature change operation is to change the set temperature in a specific direction. Further, the control device 11 skips step SC4 when the temperature change operation is not an operation to change the set temperature in a specific direction. As a result, the history DB 133 accumulates data related to temperature change operations in a specific direction.

Returning to FIG. 3, the determination unit 122 determines whether or not a predetermined period of time has elapsed since the operation data acquisition process of step SA3 was started (step SA4). The predetermined period is a preset period, and may be, for example, a period of one week, one month, several months, or longer.

When determining that the predetermined period has not passed (step SA4; NO), the determination unit 122 determines whether or not the amount of operation data RD acquired in step SA3 is excessive (step SA5). The acquisition unit 121 and the air conditioner 10A repeatedly execute the operation data acquisition process of step SA3 until the predetermined period elapses. The determination unit 122 determines whether or not the number of pieces of acquired operation data RD is too large before the predetermined period elapses. At step SA5, the determination unit 122 compares, for example, a threshold value determined corresponding to the time from the start of the operation data acquisition process at step SA3 and the number of data items stored in the history DB 133. FIG.

When the determination unit 122 determines that the acquired data is not excessive (step SA5; NO), the acquisition unit 121 returns to step SA3 and executes operation data acquisition processing with the air conditioner 10A.

When the determination unit 122 determines that the acquired data is excessive (step SA5; YES), the setting unit 123 changes the operating conditions of the air conditioner 10A (step SA6). The operating conditions include the set temperature of the air conditioner 10A. The operating conditions include the return timing of the air conditioner 10A. At step SA6, the setting unit 123 transmits to the air conditioner 10A the setting data SD designating the operating conditions of the air conditioner 10A after the change.

At step SA6, the setting unit 123 changes the operating conditions so that the number of temperature change operations in the air conditioner 10A is reduced or is less likely to increase. In other words, the operating conditions are changed so as to increase comfort in the space to be conditioned by the air conditioner 10A. For example, the set temperature is changed to a lower temperature when the air conditioner 10A is in cooling operation, and the set temperature is changed to a higher temperature during heating operation. Also, the setting unit 123 may delay the return timing. In this case, it takes longer for the set temperature changed by the temperature change operation to return to the temperature before the change, so the temperature change operation can be suppressed.

On the other hand, if it is determined that the predetermined period has passed (step SA4; YES), the determination unit 122 executes operation data determination processing (step SA7). The operation data determination process is a process of determining whether the data included in the history DB 133 is sufficient data for determining the control parameter CP.

As described above, the determination unit 122 may use the number of temperature change operations as a criterion for determining whether the data is sufficient for determining the control parameter CP. In this case, the determining unit 122 determines in step SA7 whether or not the number of temperature change operations performed in a predetermined period is equal to or greater than a preset threshold value, thereby obtaining data acquired from the air conditioner 10A. determines whether or not satisfies the conditions. Then, in step SA7, if the number of temperature change operations performed in the predetermined period is less than the threshold, the determination unit 122 determines that the data acquired from the air conditioning apparatus 10A does not satisfy the conditions, and performs the operation in the predetermined period. It is determined that the data acquired from the air conditioner 10A satisfies the condition when the number of temperature change operations received is equal to or greater than the threshold. The number of temperature change operations performed in the air conditioning apparatus 10A during a predetermined period can be determined from the temperature change operation data included in the history DB 133 .

In this embodiment, an example in which the determination unit 122 performs determination including the quality of data in the history DB 133 will be described with reference to FIG. 5 . FIG. 5 is a flow chart showing the operation data determination process executed at step SA7 in FIG.
The determination unit 122 specifies an air conditioner ID to be subjected to determination processing (step SD1), and extracts setting change history data associated with the specified air conditioner ID from the history DB 133 (step SD2).

Based on the data extracted in step SD2, the determination unit 122 counts the number of temperature change operations for each day and for each outside temperature (step SD3). Thereby, the determination unit 122 associates the number of temperature change operations per day with the outside air temperature. The determination unit 122 performs a regression analysis on the correlation between the number of temperature change operations per day and the outside air temperature, and obtains a regression line (step SD4).

Fig. 6 is a chart showing an example of a regression line. FIG. 6 is a scatter diagram plotting data with the horizontal axis representing outside air temperature and the vertical axis representing temperature change operation per day. Point P1 in the figure indicates the data collected in step SD3. FIG. 6 shows an example of a regression line obtained by regression analysis by RG1. The regression line RG1 is a straight line generated using the method of least squares, but this is an example. As the method of regression analysis, in addition to the method of least squares, geometric mean regression, principal component regression, or other methods can be used, and any method that can obtain a regression line as an approximation can be used. Alternatively, the determination unit 122 may simply perform a process of obtaining an approximate expression in step SD4.

The magnitude of the slope of the regression line RG1 indicates the degree to which the number of temperature change operations changes due to the outside temperature. A large slope of the regression line RG1 indicates that the number of times of temperature change operation changes greatly depending on the outside air temperature. Here, the magnitude of the slope of the regression line RG1 means the magnitude of the absolute value of the slope. In the example of FIG. 6, the number of temperature change operations per day has a positive correlation with the outside temperature, but it is also possible that the number of temperature change operations has a negative correlation with the outside temperature. .

Returning to FIG. 5, the determination unit 122 determines whether or not the slope of the regression line obtained in step SD4 is equal to or greater than a threshold (step SD5). The threshold is a value preset in the control unit 110 and stored in the memory 130, for example. If the slope of the regression line is equal to or greater than the threshold (step SD5; YES), the determination unit 122 determines that the data acquired from the air conditioner 10A in the operation data acquisition process satisfies the conditions (step SD6), and Return to processing.

On the other hand, when the slope of the regression line is smaller than the threshold (step SD5; NO), the determination unit 122 determines that the data acquired from the air conditioner 10A does not satisfy the conditions (step SD7), and returns to the process of FIG. .

The determination unit 122 refers to the determination result of the operation data determination process (step SA8). Here, when it is determined that the data acquired from the air conditioner 10A in the operation data acquisition process satisfies the condition (step SA8; YES), the processing unit 124 performs the control parameter generation process based on the data in the history DB 133. Execute (step SA9). The control parameter generation process will be described later.

After that, in step SA10, the operation of the air conditioner 10A based on the control parameter CP is started (step SA10). Here, the setting unit 123 transmits the control parameter CP generated in step SA9 to the air conditioner 10A, and the air conditioner 10A receives the control parameter CP. The control device 11 detects the outside air temperature with the outside air temperature sensor 18 and applies the outside air temperature to the control parameter CP to determine the set temperature of the air conditioner 10A. The control device 11 performs operation based on the set temperature determined by the control parameter CP.

When it is determined in the operation data determination process that the data does not satisfy the conditions (step SA8; NO), the setting unit 123 changes the operating conditions of the air conditioner 10A (step SA11). The details of the operating conditions are as described for step SA6.

In step SA11, the operating conditions of the air conditioner 10A in the operation data acquisition process are changed so as to facilitate acquisition of the operation data RD. That is, the setting unit 123 changes the operating conditions so that the number of temperature change operations in the air conditioner 10A is increased. This change is to change the operating conditions so that the comfort in the conditioned space of the air conditioner 10A is lowered. For example, the set temperature is changed to a higher temperature when the air conditioner 10A is in cooling operation, and the set temperature is changed to a lower temperature during heating operation. Also, the setting unit 123 may advance the return timing. In this case, since the time required for the set temperature changed by the temperature change operation to return to the temperature before the change is shortened, the temperature change operation can be accelerated. At step SA11, the setting unit 123 transmits to the air conditioner 10A the setting data SD designating the operating conditions of the air conditioner 10A after the change.

The acquisition unit 121 executes operation data acquisition processing similar to that of step SA7 (step SA12). After that, the determination unit 122 determines whether or not a predetermined period of time has passed since the operation data acquisition process of step SA12 was started (step SA13). The predetermined period is the same as step SA4.

When the determining unit 122 determines that the predetermined period has not elapsed (step SA13; NO), the process returns to step SA12. The acquisition unit 121 and the air conditioner 10A repeatedly execute the operation data acquisition process of step SA12 until the predetermined period elapses.

When determining that the predetermined period has passed (step SA13; YES), the determination unit 122 executes the operation data determination process in the same manner as in step SA7 (step SA14). After that, the determination unit 122 refers to the determination result of the operation data determination process (step SA15). Here, when it is determined that the data acquired from the air conditioner 10A in the operation data acquisition process does not satisfy the conditions (step SA15; NO), the control unit 110 returns to step SA12. Here, control unit 110 may return to step SA11 and change the operating conditions by setting unit 123 . Specifically, the operating conditions of the air conditioner 10A in the operation data acquisition process may be further changed so that the operation data RD can be acquired more easily.

If it is determined in the operation data acquisition process that the data acquired from the air conditioner 10A satisfies the conditions (step SA15; YES), the processing unit 124 proceeds to step SA9 and executes the control parameter generation process (step SA9).

FIG. 7 is a flow chart showing an example of control parameter generation processing executed in step SA9 of FIG.
The processing unit 124 identifies the air conditioner ID of the air conditioner 10 to which the control parameter CP is applied (step SE1). Here, the air conditioner ID of the air conditioner 10A is specified. Processing unit 124 extracts data corresponding to the air conditioner ID specified in step SE1 from history DB 133 (step SE2).

The processing unit 124 further extracts the outside air temperature and the set temperature changed by the temperature change operation from the data extracted in step SE2 (step SE3). The set temperature changed by the temperature change operation is called the changed temperature. The processing unit 124 performs a regression analysis for obtaining a correlation between the outside air temperature and the changed temperature, and obtains a regression line (step SE4). The method of regression analysis is as described in step SD4, and as an example, a process of obtaining an approximate expression by the method of least squares can be adopted.

FIG. 8 is a chart showing an example of a regression line, showing an example of the regression line calculated in step SE4 of FIG. FIG. 8 is a scatter diagram plotting data with the outside air temperature on the horizontal axis and the average set temperature of the air conditioner 10A on the vertical axis. The set temperature on the vertical axis is the set temperature after being changed by the temperature change operation in the air conditioner 10A. The set temperature value plotted in the chart of FIG. 7 may be an average value obtained by averaging a plurality of changed set temperature values corresponding to one outside air temperature. A point P2 in the figure indicates the data extracted in step SE3.

An example of a regression line obtained by regression analysis is indicated by RG2 in FIG. The regression line RG2 is a straight line generated using the method of least squares, but this is an example. As the method of regression analysis, in addition to the method of least squares, geometric mean regression, principal component regression, or other methods can be used, and any method that can obtain a regression line as an approximation can be used. Alternatively, the processing unit 124 may simply perform a process of obtaining an approximate expression in step SE4.

A regression line RG2 indicates the correlation between the outside air temperature and the set temperature of the air conditioner 10A set by operating the operation unit 14. For example, when the set temperature is set to a low temperature while the outside air temperature is high, this indicates that the person in the space to be harmonized feels that the space to be harmonized is hot.

Returning to FIG. 7, the processing unit 124 uses the regression line obtained in step SE4 to calculate the recommended set temperature for each outside air temperature (step SE5). The processing unit 124 generates a control parameter CP that enables the control device 11 to obtain the recommended set temperature based on the outside air temperature (step SE6). The processing unit 124 stores the generated control parameter CP in the memory 130 in association with the air conditioner ID of the air conditioner 10A (step SE7). The control parameter CP thus generated reflects the correlation between the set temperature set by the person in the space to be harmonized and the outside air temperature, as shown in FIG. In addition, the control parameter CP is a parameter that determines the set temperature of the air conditioner 10A so as to operate the air conditioner 10A so as to reduce the energy consumption of the air conditioner 10A.

The air conditioner 10A uses the control parameter CP generated in the process of FIG. 7 to determine the set temperature of the air conditioner 10A based on the outside air temperature detected by the outside air temperature sensor 18. The air conditioner 10A can perform control suitable for the environment of the space to be conditioned by the air conditioner 10A by using the control parameter CP generated using the operation data RD generated by the air conditioner 10A. Therefore, the air conditioner 10A can be operated including the influence of the environment of the building including the space to be conditioned and the sunlight in the space to be conditioned, thereby maintaining the comfort of the space to be conditioned. Furthermore, since the set temperature of the air conditioner 10A can be prevented from being set to an excessively low or high temperature, the energy consumption of the air conditioner 10A can be suppressed while maintaining the comfort of the conditioned space.

The number of times the operation in FIG. 3 is executed in the management system 1000 is not limited to one. The management system 1000 may perform the operation of FIG. 3 when the air conditioner 10 performs the cooling operation, generate control parameters CP for the cooling operation, and apply them to the air conditioner 10 . In this case, the operation of FIG. 3 is started at the timing when the air conditioner 10 starts the cooling operation. For example, when the air conditioner 10 is operated to specify the cooling operation as the operation type, the operation data RD indicating the start of the cooling operation is transmitted to the management server 100, and this operation data RD serves as a trigger for the management server. 100 performs the process of FIG. Similarly, the management system 1000 may perform the operation of FIG. 3 when the air conditioner 10 starts heating operation, generate control parameters CP for heating operation, and apply them to the air conditioner 10. .

The processing unit 124 can generate the control parameter CP for the cooling operation by extracting and using the data during the cooling operation from the history DB 133, and similarly generates the control parameter CP for the heating operation. can also

Also, the management system 1000 may perform the operation of FIG. 3 while the air conditioner 10 is operating using the control parameters CP. In this case, steps SA1 and SA2 can be omitted. For example, the operation of FIG. 3 may be performed at intervals of one year, two years, or more. In this case, the control parameter CP can be updated in response to changes in the environment of the space to be harmonized and changes in the mode of use of the space to be harmonized. In addition, when the space to be harmonized is the work place, it is possible to cope with the change of the person working in the space to be harmonized. Furthermore, the operation of FIG. 3 may be executed and the control parameter CP may be updated at the timing designated by the operation of the operation unit 14 . In this case, the control parameter CP can be updated according to the situation of the administrator who manages the air conditioner 10 and the user of the space to be conditioned.

In this case, the management system 1000 may use the management server 100 to manage the date when the control parameter CP was applied to each air conditioner 10 . The management server 100 updates the control parameter CP for which a predetermined period of time has passed since it was applied, by the operation shown in FIG.

FIG. 9 is a flowchart showing another example of control parameter generation processing. The operation of FIG. 9 is executed by the processing unit 124 instead of the operation shown in FIG.
In FIG. 9, steps SE1 to SE6 are common to the operation in FIG. After generating the control parameter CP in step SE6, the processing unit 124 counts the number of temperature change operations for each outside temperature zone based on the data extracted in step SE2 (step SE11).

The processing unit 124 generates additional data to be added to the control parameter CP (step SE12). In step SE12, the processing unit 124 determines the allowable number of temperature change operations for each outside air temperature zone and the temperature range that can be changed by the temperature change operation, based on the number of times counted in step SE11. Then, the processing unit 124 generates additional data indicating the determined allowable number of times and the temperature range.

The processing unit 124 updates the control parameter CP by adding the additional data generated in step SE12 to the control parameter CP generated in step SE6, and stores the updated control parameter CP in the memory 130 (step SE13).

The allowable number of temperature change operations determined in step SE12 refers to whether or not the air conditioner 10A allows temperature change operations, and the number of temperature change operations accepted by the air conditioner 10A per day or per predetermined time period. Point to the number of times. The allowable number of temperature change operations may be, for example, once, three, five, or the like per day or per predetermined period of time. In addition, the processing unit 124 can set the allowable number of temperature change operations to 0, that is, determine not to allow the temperature change operation. The processing unit 124 determines the allowable number of temperature change operations for each outside air temperature zone. The width of the outside air temperature zone may be determined appropriately, and may be, for example, a width of 5°C, 2°C, or 1°C.

The temperature range of the temperature change operation refers to the temperature range in which the set temperature of the air conditioner 10A can be changed by the temperature change operation. For example, the processing unit 124 has a first threshold T1 and a second threshold T2 as thresholds for the number of temperature change operations, where T1>T2. For the first outside air temperature zone, if the number of times NT of temperature change operations counted in step SE11 is T1<NT, processing unit 124 sets the temperature range that can be changed by the temperature change operation in the first outside air temperature zone to ± 5°C. For the second outside air temperature zone, if the number of times N of temperature change operations counted in step SE11 is T2<NT<T1, the processing unit 124 determines the temperature range that can be changed by the temperature change operation in the second outside air temperature zone. shall be ±3°C. For the third outside air temperature zone, if the number of times N of temperature change operations counted in step SE11 is NT<T2, the processing unit 124 adjusts the temperature range that can be changed by the temperature change operation in the third outside air temperature zone. 1°C. Further, when the number NT of temperature change operations counted in step SE11 for the fourth outside air temperature zone is 0, the processing unit 124 sets the changeable temperature range by the temperature change operation to 0 in the fourth outside air temperature zone. °C.

According to the operation example of FIG. 9, it is possible to allow the temperature change operation while the air conditioner 10A is being operated based on the control parameter CP within an appropriate range. Therefore, it is possible to further improve the comfort of people in the space to be conditioned by the air conditioner 10A.

In the operation example of FIG. 9, the control parameter CP may include a time limit from when the temperature change operation is performed until the set temperature is restored to the state before the change. That is, in addition to the temperature range that can be changed by the temperature changing operation, or instead of this, additional data indicating the time limit may be included in the control parameter CP. For example, the control parameter CP may specify a long time limit in association with the outside air temperature range in which the temperature change operation is performed frequently, and may specify a short time limit in association with the outside air temperature range in which the temperature change operation is performed frequently. good. The time limit may be determined stepwise, for example, 30 minutes, 60 minutes, 120 minutes, and the like.

FIG. 10 is a flowchart showing another example of control parameter generation processing. The operation of FIG. 10 is executed by the processing unit 124 instead of the operation shown in FIG. 7 or 9. FIG.

In FIG. 10, steps SE1 to SE5 are common to the operation in FIG.
Based on the recommended set temperature calculated in step SE5, the processing unit 124 performs a process of generating a first control parameter CP (step SE21) and a process of generating a second control parameter CP (step SE22). Execute.

Both the first control parameter CP and the second control parameter CP enable the control device 11 in the air conditioner 10A to obtain the recommended set temperature based on the outside air temperature. Among these, the first control parameter CP is used when the air conditioner 10A performs normal operation. The second control parameter CP is used when the air conditioner 10A performs energy saving operation. That is, processing unit 124 generates control parameters CP for normal operation and control parameters CP for energy saving operation in steps SE21 and SE22. The process of FIG. 10 is effective when the air conditioner 10A can switch between normal operation and energy saving operation by operating the operation unit 14 .

Based on the data extracted in step SE2, the processing unit 124 tallies the number of temperature change operations for each outside temperature zone (step SE23). Processing unit 124 generates additional data to be added to control parameter CP (step SE24). In step SE24, the processing unit 124 determines the allowable number of temperature change operations for each outside air temperature zone and the temperature range that can be changed by the temperature change operation, based on the number of times counted in step SE22. This process is the same as step SE12. Furthermore, in step SE24, the processing unit 124 generates first additional data to be applied to the first control parameter CP and second additional data to be applied to the second control parameter CP.

When the first control parameter CP is for normal operation and the second control parameter CP is for energy-saving operation, the second additional data has a narrower range of temperature change operation than the first additional data. For example, in the second additional data, the allowable number of temperature change operations in the same outside air temperature range is smaller than in the first additional data, and the changeable temperature range is narrow.

The processing unit 124 updates the control parameter CP and stores it in the memory 130 (step SE25). At step SE25, the processing unit 124 updates the first control parameter CP by adding the first additional data to the first control parameter CP. Also, the second control parameter CP is updated by adding the second additional data to the second control parameter CP. The processing unit 124 stores the updated first control parameter CP and second control parameter CP in the memory 130 in association with the air conditioner ID of the air conditioner 10A.

According to the operation example of FIG. 10, the manager of the air conditioner 10A switches the operating state of the air conditioner 10A between the normal operation and the energy-saving operation. set temperature can be set. As a result, the balance between the comfort of the space to be conditioned and the energy consumption can be changed according to the manager's request within a range that does not impair the comfort of the space to be conditioned by the air conditioner 10A.

The processing of steps SE21, SE22, and SE25 described in FIG. 10 can also be applied to steps SE6 and SE7 of FIG. In this case, the control parameters CP for normal operation and energy-saving operation can be generated in a manner that does not include the allowable number of temperature change operations and the changeable temperature range.

Thus, in the management system 1000, the management server 100 generates control parameters CP suitable for each air conditioner 10, and operates the air conditioner 10 based on the control parameters CP. As a result, each air conditioner 10 can reduce energy consumption while maintaining the comfort of the space to be conditioned.

FIG. 11 is an explanatory diagram showing how the air conditioner 10 operates based on the control parameters CP. FIG. 11 shows an example of the set temperature of the air conditioner 10 that is set corresponding to the outside air temperature based on the control parameter CP. Further, FIG. 11 shows the set temperatures in the energy saving operation as a comparative example.

Air conditioners 1, 2, 3, and 4 in FIG. 11 indicate different air conditioners 10, respectively. For example, the air conditioner 1 refers to the air conditioner 10A. Similarly, it may be considered that the air conditioner 2 refers to the air conditioner 10B, the air conditioner 3 refers to the air conditioner 10C, and the air conditioner 4 refers to the air conditioner 10D. Further, FIG. 11 shows, as an example, a case where the control parameter CP is applied during cooling operation.

As described above, the set temperature for energy-saving operation is, for example, 28°C regardless of the outside air temperature. On the other hand, if the control parameter CP is applied, the air conditioner 10 can determine the set temperature suitable for the installation environment of the air conditioner 10 according to the outside air temperature.

For example, the air conditioner 1 in FIG. 11 sets the set temperature to 25°C when the outside temperature is lower than 22°C, and sets the set temperature to 24°C when the outside temperature is 23°C or higher and lower than 26°C. On the other hand, the air conditioner 2 sets the set temperature to 28°C when the outside air temperature is lower than 24°C. Different control parameters CP are provided from the management server 100 to the air conditioners 10A, 10B, 10C, and 10D. Therefore, as illustrated in FIG. 11, each air conditioner 10 can determine different set temperatures for the same outside air temperature.

Since the set temperatures of the air conditioner 10 during the cooling operation shown in FIG. 11 are all lower than the set temperatures during the energy saving operation, comfort in the space to be conditioned is improved. Also, by changing the set temperature of the air conditioner 10 according to the outside air temperature, so-called excessive cooling can be avoided, and energy consumption of the air conditioner 10 can be suppressed. A similar effect can be obtained during heating operation.

The management system 1000 also has a function of visualizing changes in the energy consumption of the air conditioner 10 and the comfort of the space to be conditioned before and after applying the control parameter CP, and providing this to the administrator.

FIG. 12 is a sequence diagram showing the operation of the management system 1000. FIG. Steps SF1 to SF7 in FIG. 12 show operations of the management server 100, and steps SG1 to SG3 show operations of the terminal device 5. FIG. The mobile terminal device 7 may perform the operations of steps SG1 to SG3.

The terminal device 5 transmits a comparison data request to the management server 100 according to the operation of the administrator who uses the terminal device 5 (step SG1). The comparison data request includes an air conditioner ID that identifies the air conditioner 10 for which comparison data is to be generated. The comparison data request may specify the type of comparison data. The types of comparison data include, for example, one or more of power consumption comparison and the number of temperature change operations. In the following description, a case where power consumption comparison is designated as the type of comparison data will be described.

The acquisition unit 121 receives the comparison data request transmitted by the terminal device 5 (step SF1). Processing unit 124 identifies the air conditioner ID included in the comparison data request (step SF2).

FIG. 13 is a diagram showing an example of display data based on comparison data.
FIG. 13 is a scatter diagram plotting data with the outside air temperature on the horizontal axis and the power consumption per day or per predetermined period on the vertical axis. FIG. 13 shows comparison data comparing power consumption when the air conditioner 10A performs normal operation without using the control parameter CP, energy-saving operation without using the control parameter CP, and operation using the control parameter CP. indicates Normal operation is operation in a state in which temperature change operations can be executed without restriction by operating the operation unit 14 . The energy-saving operation is an operation in which the set temperature of the air conditioner 10A is set to a temperature determined by the Ministry of Economy, Trade and Industry and the like. The set temperature in energy saving operation is, for example, 28° C. during cooling operation and 20° C. during heating operation. In the energy-saving operation, the temperature change operation cannot be performed, or the number of temperature change operations or the changeable temperature range is more severely restricted than in the normal operation.

Point P3 in the figure indicates data for normal operation without control parameter CP, and point P4 indicates data for energy saving operation without control parameter CP. Point P5 indicates data for operation using the control parameter CP.

The data displayed in FIG. 13 includes a regression curve obtained by regression analysis to facilitate data comparison. Symbol RG3 indicates a regression curve obtained by regression analysis of the data of point P3. Symbol RG4 is a regression curve resulting from regression analysis of data at point P4, and symbol RG5 is a regression curve resulting from regression analysis of data at point P5. These regression curves are obtained by the processing unit 124 performing regression analysis in step SF5. The method of regression analysis can be the method of least squares, geometric mean regression, principal component regression, or other methods, and is appropriately selected as described above. The regression curves RG3, RG4, RG5 may be straight lines.

The display data in FIG. 13 visualizes and presents to the administrator how the power consumption of the air conditioner 10A changes depending on whether the air conditioner 10A uses the control parameter CP or not. For example, it is shown that the air conditioner 10A uses the control parameter CP to reduce power consumption more than when the energy saving operation is performed without using the control parameter CP.

FIG. 14 is a diagram showing another example of display data based on comparison data.
FIG. 14 shows comparison data comparing the execution status of the temperature changing operation in the air conditioner 10A. That is, FIG. 14 is a scatter diagram plotting data with the outside air temperature on the horizontal axis and the number of temperature change operations per day or predetermined time on the vertical axis.

The data in FIG. 14 compare temperature changing operations when the air conditioner 10A performs normal operation without using the control parameter CP, energy saving operation without using the control parameter CP, and operation using the control parameter CP. .

A point P6 in the figure indicates data for normal operation without using the control parameter CP, and a point P7 indicates data for energy saving operation without using the control parameter CP. Point P8 indicates data for operation using the control parameter CP.

The data displayed in FIG. 14 includes a regression curve obtained by regression analysis to facilitate data comparison. Symbol RG6 indicates a regression curve obtained by regression analysis of the data of point P6. Symbol RG7 is a regression curve obtained by regression analysis of data at point P7, and symbol RG8 is a regression curve obtained by regression analysis of data at point P8. These regression curves are obtained by the processing unit 124 performing regression analysis in step SF5.

The display data in FIG. 14 visualizes and presents to the administrator the number of times the temperature change operation has been performed in the space to be conditioned for each of the cases where the air conditioner 10A uses the control parameter CP and where it does not. The temperature changing operation is performed by a person in the space to be harmonized in order to improve the comfort of the space to be harmonized. Therefore, it can be considered that the greater the number of temperature change operations, the lower the comfort of the space to be harmonized. Also, from the viewpoint of energy saving, it is effective to limit the temperature changing operation, and the point P7 and the regression curve RG7 indicate that the temperature changing operation is limited in the energy saving operation.

In the example of FIG. 14, when the air conditioner 10A uses the control parameter CP, the number of temperature change operations is reduced compared to normal operation without using the control parameter CP. In other words, it can be said that the comfort of the harmonized space is improved by using the control parameter CP.

The display data in FIGS. 13 and 14 are visualizations of data relating to any one of the air conditioners 10 connected to the management server 100. FIG. This is just an example, and for example, data obtained by comparing power consumption or the number of temperature change operations in a plurality of air conditioners 10 may be visualized as one piece of display data and displayed on the
