Means for Solving the Problems

[0005] The air conditioning system of the present disclosure is an air conditioning system that air conditions an air-conditioned space by an air conditioner, and includes a determination unit that determines an optimal set temperature to be set in the air conditioner, and an acquisition unit that acquires environmental information of the air-conditioned space. The determination unit is an air conditioning system that determines an operation mode of the air conditioner based on the determined set temperature and the environmental information acquired by the acquisition unit.

[0006] The control method for an air conditioning system of the present disclosure is a control method for an air conditioning system that air-conditions a space to be air-conditioned using an air conditioning device, wherein the processor is instructed to perform a process of determining the optimal set temperature to be set in the air conditioning device and a process of acquiring environmental information of the space to be air-conditioned, and the determination process determines the operating mode of the air conditioning device based on the determined set temperature and the environmental information acquired by the acquisition process.

[0007] The program of this disclosure causes a processor mounted on an information processing device to perform the following: a process to determine the optimal set temperature to be set in an air conditioning device that air-conditions a space to be air-conditioned; and a process to acquire environmental information of the space to be air-conditioned. The determining process determines the operating mode of the air conditioning device based on the determined set temperature and the environmental information acquired by the acquisition process. [Effects of the Invention]

[0008] The air conditioning system, control method for the air conditioning system, and program described herein determine the operating mode of the air conditioning unit based on the optimal set temperature determined by the determination unit and acquired environmental information, thereby enabling the air conditioning unit to operate in an operating mode corresponding to the set temperature and environmental information. This improves user comfort and suppresses an increase in energy consumption of the air conditioning unit. [Brief explanation of the drawing]

[0010] (Knowledge and other information that formed the basis of this disclosure) At the time the inventors conceived this disclosure, there was a technology that allowed for changing the set temperature of an air conditioner in response to changes in the outside air temperature. However, even if the set temperature of an air conditioner is changed based on the outside air temperature, comfort in the conditioned space is not guaranteed. Therefore, users may change the set temperature of the air conditioner in order to improve the comfort of the conditioned space. Generally, when the set temperature of an air conditioner is changed, users tend to demand excessive comfort, and when the set temperature is changed, the energy consumption of the air conditioner tends to increase. Furthermore, even if a target temperature is set on the air conditioner, if this target temperature is higher than the room temperature and the air conditioner is operating in heating mode, or if the target temperature is lower than the room temperature and the air conditioner is operating in cooling mode, it takes time for the room temperature to reach the target temperature. The inventors discovered that this makes it difficult to improve user comfort and suppress the increase in energy consumption of the air conditioner, and the subject of this disclosure was created to solve this problem. Furthermore, excessive pursuit of comfort refers to, for example, setting the temperature unnecessarily low during cooling operation, or setting the temperature unnecessarily high during heating operation. Therefore, this disclosure provides an air conditioning system, a control method for the air conditioning system, and a program that can improve user comfort and suppress an increase in energy consumption of the air conditioning system.

[0011] The embodiments will be described in detail below with reference to the drawings. However, some unnecessarily detailed explanations may be omitted. For example, detailed explanations of already well-known matters or redundant explanations of substantially identical configurations may be omitted. The attached drawings and the following description are provided to enable those skilled in the art to fully understand this disclosure and are not intended to limit the subject matter described in the claims.

[0012] (Embodiment) [1. Configuration of the Embodiment] [1-1. Air Conditioning System Configuration] Figure 1 shows the system configuration of the air conditioning system 1000. The air conditioning system 1000 is a system that air-conditions a space S using an air conditioning device 1. The operating modes of the air conditioning operation performed by the air conditioning device 1 include cooling operation, heating operation, dehumidification operation, fan operation, and ventilation, but in this embodiment, the case in which the air conditioning operation performed by the air conditioning device 1 is cooling operation and heating operation will be described. The space S is a space owned by a facility H and is the space that the air conditioning device 1 air-conditions. Examples of facilities H include houses, offices, shops, medical facilities, and public facilities.

[0013] The air conditioning system 1000 includes an air conditioning unit 1. Figure 1 shows a case where the air conditioning system 1000 includes four or more air conditioning units 1, but the number of air conditioning units 1 included in the air conditioning system 1000 is not limited to four or more, and may be less than four. The air conditioning unit 1 includes an indoor unit 11 and an outdoor unit 12, and performs air conditioning operation using the indoor unit 11 and the outdoor unit 12 to air condition the air-conditioned space S in which the indoor unit 11 is installed. The air conditioning unit 1 is connected to a network NW and communicates with devices connected to the network NW. The network NW is a communication network consisting of a public telephone network, a dedicated line, the internet, or other communication networks.

[0014] The air conditioning system 1000 includes a management server 3. The management server 3 is a server device that manages the air conditioner 1 and corresponds to an information processing device. The management server 3 is connected to the network NW and performs information processing with the air conditioner 1 as a client. Note that the management server 3 may be a server device owned by the administrator P or may not be a server device owned by the administrator P.

[0015] The air conditioning system 1000 includes a weather server 4. The weather server 4 is a server device that provides a service for providing weather data. The weather data provided by the server includes at least a forecast value of the outside air temperature of the facility H.

[0016] In each figure, the management server 3 and the weather server 4 are each represented by one block, but this does not necessarily mean that the management server 3 and the weather server 4 are constituted by a single device. For example, the management server 3 and the weather server 4 may be configured to include a plurality of server devices with different processing contents, or may be configured by the same server device.

[0017] [1-2. Configuration of the air conditioner] Referring to FIG. 1, the configuration of the air conditioner 1 will be described. The air conditioner 1 includes an indoor unit 11, an outdoor unit 12, a remote controller 13, and a communication device 14. Note that the air conditioner 1 may be configured to include a plurality of indoor units 11 and outdoor units 12.

[0018] The indoor unit 11 and the outdoor unit 12 are connected by a refrigerant pipe and a control wiring. Thereby, in the air conditioner 1, a refrigerant cycle is constituted by the indoor unit 11 and the outdoor unit 12.

[0019] The remote controller 13 is installed on the wall surface of the air-conditioned space S or the like. The remote controller 13 includes a plurality of operation buttons for a user of the air conditioner 1 to perform an operation to start or stop the operation, a menu operation, a cursor key operation, and the like. Further, the remote controller 13 includes, for example, a display panel for displaying the set temperature of the air conditioner 1, the operating state of the indoor unit 11, and the like.

[0020] The communication device 14 is connected to the network NW and communicates with the management server 3. The communication device 14 also controls various parts of the air conditioning unit 1. Whenever there is a change in the set temperature of the air conditioning unit 1, the communication device 14 sends operation data RD to the management server 3.

[0021] Operation data RD is data indicating that an operation to change the set temperature has been accepted. Operation data RD includes organization ID (Identification), group ID, air conditioner ID, change date and time, operating mode information, set temperature before change, and set temperature after change. The Organization ID is information that identifies the organization, such as a company or group, that owns the air conditioning unit 1. The group ID is information used to group air conditioning units owned by the organization with the organization ID. For example, air conditioning units installed on the same floor or in the same room may be assigned the same group ID. The air conditioner ID is information that identifies air conditioning unit 1. The change date and time is the date and time when the set temperature of air conditioner 1 was changed. The operating mode information indicates the type of air conditioning operation performed by the air conditioning unit 1, and in this embodiment, it indicates either cooling or heating. The pre-change setting temperature is the pre-change setting temperature for air conditioner 1. The post-change setting temperature is the post-change setting temperature for air conditioner 1.

[0022] Furthermore, the communication device 14 acquires the room temperature of the air-conditioned space S from the remote control 13 at predetermined intervals and transmits measurement data TD, including the acquired room temperature, to the management server 3. The measurement data TD includes the organization ID, group ID, and air conditioner ID. The predetermined interval is arbitrary and may be, for example, 30 minutes or 1 hour. The room temperature is measured, for example, by the remote control 13, and the room temperature measured by the remote control 13 is output to the communication device 14.

[0023] Furthermore, the communication device 14 receives setting data SD from the management server 3. Setting data SD is data that instructs the set temperature and the operating mode of the air conditioning system to be set on the air conditioning system 1. When the communication device 14 receives the setting data SD, it sets the set temperature included in the received setting data to the target temperature of the air conditioning system 1, and sets the operating mode included in the setting data SD to the operating mode of the air conditioning system 1.

[0024] [1-3. Configuration of the Management Server] Figure 2 shows the configuration of the management server 3. The management server 3 comprises a server control device 30 and a server communication device 31.

[0025] The server control device 30 includes a server processor 300 such as a CPU (Central Processing Unit) and an MPU (Micro Processing Unit), server memory 310, and an interface circuit for inputting and outputting data.

[0026] The server memory 310 is a memory that stores programs and data. The server memory 310 stores the control program 311, the management DB (Database) 312, and calculation data calculated by the server processor 300. The server memory 310 has a non-volatile storage area. Alternatively, the server memory 310 may also have a volatile storage area that constitutes the work area of ​​the server processor 300. The server memory 310 is composed of, for example, ROM (Read Only Memory) or RAM (Random Access Memory).

[0027] Management DB312 is a database that manages data related to air conditioning unit 1. Management DB312 has one record R for each air conditioning unit 1. Each record R includes organization ID, group ID, air conditioner ID, communication information, facility location information, operating mode information, current set temperature, room temperature data, and management data MD. The communication information is information for communicating with the air conditioning device 1, and is, for example, the address information of the communication device 14. The facility location information is information indicating the location of facility H where the air conditioning unit 1 is installed, and is, for example, the address of facility H. The operating mode information indicates the type of air conditioning operation performed by the air conditioning unit 1, and in this embodiment, it indicates either cooling or heating. The currently set temperature is the temperature set in air conditioning unit 1. Room temperature data corresponds to an example of environmental information. Room temperature data is data transmitted from the air conditioning unit 1 as measurement data TD. The server control device 30 registers the room temperature data included in the received measurement data TD in the corresponding record R of the management DB 312. In this embodiment, the case where the environmental information is room temperature is illustrated as an example, but it is also possible to include room temperature and humidity in the environmental information. Management data MD is data that manages information regarding changes in the set temperature of the air conditioning unit 1 during cooling and heating.

[0028] Figure 3 shows an example of management data MD. The management data MD records time periods in one-hour increments from 0:00 to 23:59. More specifically, for each of the time periods from 0:00 to 23:00, the management data MD records time periods from N:00 to N:59, where N is an integer between 0 and 23.

[0029] Furthermore, the management data MD records multiple ambient temperatures in 1°C increments. The range of ambient temperatures recorded in the management data MD includes at least the range of temperatures that the ambient air at facility H can reach. The range of ambient temperatures recorded in the management data MD may be the same regardless of the location of facility H, or it may be a different range depending on the location of facility H.

[0030] The management data MD records one collected data AD, which is a pair of one time period and one outside air temperature. The collected data AD contains information about the history of changes to the set temperature of the air conditioner 1. The collected data AD includes the set temperature, the number of changes, the number of changes, and the probability of change. Based on the data contained in the collected data AD, the set temperature to be set for the air conditioner 1 is determined.

[0031] The collected data AD records the set temperatures of multiple air conditioning units 1 in 1°C increments. Figure 3 shows an example where 23°C, 24°C, 25°C, 26°C, and 27°C are recorded as collected data AD, but the range of set temperatures included in the collected data AD is arbitrary.

[0032] The collected data AD records the number of actual sessions, the number of changes, and the probability of changes for each recorded set temperature. In the example in Figure 3, the collected data AD records the number of actual sessions, the number of changes, and the probability of changes for each set temperature of 23°C, 24°C, 25°C, 26°C, and 27°C. The "actual count" indicates the number of times the corresponding set temperature was set in air conditioner 1. The number of changes indicates the number of times the temperature setting has been changed from one setting to another. The change probability indicates the probability that the temperature was changed from a corresponding set temperature to another set temperature. The change probability is calculated by dividing the number of corresponding changes by the number of actual changes.

[0033] Returning to the explanation of Figure 2, the server communication device 31 is equipped with hardware such as a communication circuit that conforms to a predetermined communication standard, and communicates with the air conditioning device 1 and the weather server 4 according to the control of the server control device 30.

[0034] The server processor 300 functions as a communication control unit 301, acquisition unit 302, update unit 303, determination unit 304, and setting unit 305 by reading and executing the control program 311 stored in the server memory 310.

[0035] The communication control unit 301 communicates with the air conditioning unit 1 and the weather server 4 via the server communication device 31.

[0036] The acquisition unit 302 acquires the outside air temperature. The acquisition unit 302 processes one record R and acquires the outside temperature based on the record R being processed. More specifically, the acquisition unit 302 generates forecast value request information based on the record R being processed and outputs the generated forecast value request information to the communication control unit 301. The forecast value request information is a request to acquire a forecast value of the outside temperature for a time period including the current time, and includes the location of the facility H recorded in the record R being processed and the time period for which the request is made. For example, if the current time is H hours and M minutes, the forecast value request information will record the time period from H hours and 0 minutes to H+1 hours and 0 minutes. H is an integer from 0 to 24, and M is an integer from 0 to 59. When the communication control unit 301 receives the forecast value request information from the acquisition unit 302, it transmits the received forecast value request information to the weather server 4. The communication control unit 301 then receives multiple forecast values ​​from the weather server 4 that correspond to the location of the facility H and the time period recorded in the transmitted forecast value request information. The acquisition unit 302 calculates the average of the forecast values ​​received by the communication control unit 301 and acquires the calculated average value as the outside air temperature. In this embodiment, when calculating the average of the forecast values, the acquisition unit 302 either truncates the decimal part or rounds it to the nearest whole number.

[0037] The update unit 303 updates the management DB 312. The update unit 303 updates the actual count recorded in the collected data AD at L minutes past every hour. The update unit 303 updates the actual count for each record R. Here, L is an integer from 0 to 59, for example, 0. To elaborate on the updating of the actual count, at L minutes past every hour, the update unit 303 first causes the acquisition unit 302 to acquire the outside temperature based on the record R to be processed. Next, the update unit 303 refers to the management data MD of the record R to be processed and identifies the collected data AD corresponding to the time period including the current time and the pair of outside temperature and degree acquired by the acquisition unit 302.

[0038] In detail, the update unit 303 identifies one of the collected data ADs included in the management data MD. Next, the update unit 303 increments by 1 the number of actual values ​​recorded in the identified collected data AD that corresponds to the current set temperature recorded in the record R to be processed. The update unit 303 also updates the change probability corresponding to the incremented number of actual values ​​to reflect the change probability after the increment.

[0039] Now, referring to Figure 4, we will explain how to update the actual figures. Figure 4 is a diagram illustrating the update of the performance figures. The explanation in Figure 4 illustrates a case where the current time when updating the actual count is in the 2 PM hour, and the outside air temperature acquired by the acquisition unit 302 is 34°C. The explanation in Figure 4 also illustrates a case where the air conditioning unit 1 is operating in cooling mode. In the case of Figure 4, the update unit 303 identifies the collected data AD corresponding to the time period in the 2 PM hour and the outside air temperature of 34°C from the management data MD recorded in the record R to be processed.

[0040] In the explanation of Figure 4, we illustrate the case where the current set temperature recorded in the record R to be processed is 25°C. That is, in the explanation of Figure 4, we illustrate the case where the set temperature set in the air conditioner 1 is 25°C. In the case of Figure 4, the update unit 303 increments the number of actual occurrences corresponding to 25°C from "4" to "5" among the actual occurrences recorded in the identified collected data AD. Also, in the case of Figure 4, along with the update of the actual occurrences, the update unit 303 updates the change probability corresponding to 25°C from "3 / 4" to "3 / 5".

[0041] Next, we will explain the update operation of the update unit 303 based on the operation data RD received by the communication control unit 301. The communication control unit 301 receives operation data RD and outputs the received operation data RD to the update unit 303. The update unit 303 updates the management DB 312 based on the operation data RD input from the communication control unit 301. The update unit 303 identifies record R from the management DB 312 that contains the organization ID, group ID, and air conditioner ID of the input operation data RD. Next, the update unit 303 updates the current set temperature of the identified record R to the changed set temperature recorded in the input operation data RD.

[0042] Next, the update unit 303 instructs the acquisition unit 302 to acquire the outside air temperature based on the record R identified by the input operation data RD. Then, the update unit 303 identifies the collected data AD corresponding to the time period including the current time and the outside air temperature / degrees acquired by the acquisition unit 302 from the management data MD of the identified record R.

[0043] Next, the update unit 303 refers to the input operation data RD, and if the changed set temperature is lower than the changed set temperature, it increments the number of changes recorded in the identified collected data AD that corresponds to the changed set temperature recorded in the input operation data RD by 1. Furthermore, the update unit 303 also updates the change probability corresponding to the incremented number of changes to reflect the change probability after the increment.

[0044] Now, referring to Figure 5, we will explain how to update the number of changes. Figure 5 is a diagram illustrating the update of the number of changes. Figure 5 illustrates a case where the current time when updating the number of changes is in the 2 PM hour, and the outside temperature acquired by the acquisition unit 302 is 34°C. Figure 5 also illustrates a case where the air conditioning unit 1 is operating in cooling mode. The update unit 303 identifies the collected data AD corresponding to the 2 PM hour and the outside temperature of 34°C from the first management data MD1 recorded in the record R to be processed.

[0045] In the example shown in Figure 5, the case where the pre-change setting temperature recorded in the input operation data RD is 25°C is illustrated. In the explanation of Figure 5, the case where the post-change setting temperature recorded in the input operation data RD is 24°C is illustrated. In this example, the update unit 303 increments the number of changes corresponding to 25°C from "3" to "4" among the number of changes recorded in the identified collected data AD. Also, in the case of Figure 5, the update unit 303 updates the change probability corresponding to 25°C from "3 / 4" to "4 / 4" along with the update of the number of changes.

[0046] Returning to the explanation of Figure 2, the determination unit 304 determines the set temperature to be set in the air conditioner 1 and the operating mode for air conditioning operation based on the number of times each temperature has been set, the number of times this set temperature has been changed, the probability that the set temperature will be changed, etc. Details of the determination method of the determination unit 304 will be described later.

[0047] The setting unit 305 sets the set temperature and operating mode determined by the determination unit 304 to the air conditioner 1. The setting unit 305 sets the set temperature and operating mode to the air conditioner 1 based on the record R to be processed. More specifically, the setting unit 305 generates setting data SD including the set temperature and operating mode, and outputs the generated setting data SD and the communication information recorded in the record R to be processed to the communication control unit 301. Based on the communication information received from the setting unit 305, the communication control unit 301 transmits the setting data SD received from the setting unit 305 to the air conditioner 1. The air conditioner 1 receives the setting data SD via the communication device 14. The air conditioner 1 extracts the set temperature and operating mode contained in the setting data SD, sets the operating mode of the air conditioner 1 to the extracted operating mode, and changes the target temperature to the extracted set temperature.

[0048] [2. Operation of the Embodiment] Next, the operation of each part of the air conditioning system 1000 according to this embodiment will be described. Figures 6 and 7 are flowcharts showing the operation of the management server 3.

[0049] The flowcharts in Figures 6 and 7 are flowcharts that start at K minutes past every hour. Here, K is an integer from 0 to 59, for example, 0. Furthermore, the flowcharts in Figures 6 and 7 are flowcharts performed for each air conditioning unit 1. In other words, the flowcharts in Figures 6 and 7 are operations performed for each record R stored in the management DB 312.

[0050] The acquisition unit 302 acquires the outside temperature based on the record R to be processed (step SA1). Step SA1 is described in detail below. The acquisition unit 302 generates forecast value request information based on the record R to be processed and outputs the generated forecast value request information to the communication control unit 301. For example, if the current time is 10:00, the forecast value request information records the time period from 10:00 to 11:00. When the communication control unit 301 receives the forecast value request information from the acquisition unit 302, it transmits the received forecast value request information to the weather server 4. The communication control unit 301 then receives from the weather server 4 multiple forecast values ​​(for example, the forecast value for 10:00 and the forecast value for 11:00) corresponding to the location and time period of the facility H recorded in the transmitted forecast value request information. The acquisition unit 302 calculates the average of the forecast values ​​received by the communication control unit 301 and acquires the calculated average value as the outside temperature.

[0051] Next, the determination unit 304 identifies the collection data AD to be processed from the management data MD recorded in the record R to be processed (step SA2).

[0052] Step SA2 will be described in detail. The determination unit 304 identifies the collected data AD corresponding to the time period including the current time and the outdoor temperature temperature acquired in step SA1 from the management data MD recorded in the record R to be processed. Here, the time period including the current time is treated as the target time to determine the set temperature to be set in the air conditioner 1, but a future time period, such as 3 hours later, may also be treated as the target time.

[0053] Next, the determination unit 304 performs a determination process to determine the set temperature based on the identified collected data AD (step SA3). The determination process is the process for determining the set temperature to be set in the air conditioner 1. In the determination process, the collected data AD identified in step SA2 is the target of processing. For details of the determination process, refer to the flowchart shown in Figure 7.

[0054] Next, the decision unit 304 obtains the room temperature from the management DB 312 and compares the obtained room temperature with the set temperature determined in the decision process (step SA4). If the obtained room temperature is lower than the determined set temperature (step SA4 / NO), the decision unit 304 determines the operating mode of the air conditioner 1 to be heating operation (step SA6). If the obtained room temperature is higher than the determined set temperature (step SA4 / YES), the decision unit 304 determines the operating mode of the air conditioner 1 to be cooling operation (step SA5).

[0055] Next, the setting unit 305 generates setting data SD, which includes the determined set temperature and operating mode (step SA7), and outputs it to the communication control unit 301. The communication control unit 301 transmits the setting data SD input from the setting unit 305 to the air conditioner 1 (step SA8).

[0056] Figure 7 is a flowchart showing the operation of the decision unit 304 in the decision process. The determination unit 304 determines whether the set temperature included in the collected data AD to be processed satisfies the following first condition (step SA301). Condition 1: There must be a first set temperature and a second set temperature.

[0057] The first set temperature is a set temperature where the corresponding change probability is above a predetermined threshold. An example of a predetermined threshold is 0.1 (10%). The second set temperature is a temperature that is lower than the first set temperature included in the collected data AD, and is registered as one temperature below the first set temperature, and whose corresponding change probability is less than a predetermined threshold.

[0058] Here, we will explain the first set temperature and the second set temperature using Figure 3. The collected data AD shown in Figure 3 shows that a change probability of "0 / 3" is recorded for a set temperature of 23°C, a change probability of "0 / 1" is recorded for a set temperature of 24°C, a change probability of "3 / 4" is recorded for a set temperature of 25°C, a change probability of "2 / 3" is recorded for a set temperature of 26°C, and a change probability of "4 / 4" is recorded for a set temperature of 27°C.

[0059] When the predetermined threshold is 0.1, in the example of collected data AD shown in Figure 3, 25°C, 26°C, and 27°C correspond to the first set temperature, and 24°C, which is registered as one temperature lower than the first set temperature, corresponds to the second set temperature. Note that the collected data AD shown in Figure 3 satisfies the first condition described above.

[0060] Returning to the explanation of the flowchart shown in Figure 7, if the decision unit 304 determines that the first condition is met (step SA301: YES), it determines whether there are multiple second set temperatures in the set temperature data AD to be processed (step SA302).

[0061] If the determination unit 304 determines that there are no multiple second set temperatures (step SA302: NO), it determines the second set temperature as the set temperature to be set on the air conditioner 1 (step SA303).

[0062] Here, we will use Figure 3 to explain step SA303 in detail. When the predetermined threshold is 0.1, in the collected data AD shown in Figure 3, 24°C is the second set temperature, and the other set temperatures do not correspond to the second set temperature. Therefore, when the predetermined threshold is 0.1 and the collected data AD to be processed is the collected data AD shown in Figure 3, the determination unit 304 determines in step 303 that 24°C is the set temperature to be set for the air conditioner 1.

[0063] On the other hand, if the determination unit 304 determines that there are multiple second set temperatures (step SA33: YES), it determines the second set temperature that best maximizes the comfort of the air-conditioned space S among the set temperatures recorded in the collected data AD to be processed as the set temperature to be set on the air conditioning unit 1 (step SA304).

[0064] The setting temperature that maximizes the comfort of the air-conditioned space S among the setting temperatures recorded in the collected data AD is the lowest setting temperature among the setting temperatures recorded in the collected data AD, when the air conditioning system 1 is performing cooling.

[0065] Now, with reference to Figure 8, step SA304 will be explained in detail. Figure 8 shows an example of collected data (AD). The collected data AD shown in Figure 8 records a change probability of "0 / 3" for a set temperature of 23°C, a change probability of "1 / 4" for a set temperature of 24°C, a change probability of "0 / 2" for a set temperature of 25°C, a change probability of "2 / 3" for a set temperature of 26°C, and a change probability of "4 / 4" for a set temperature of 27°C.

[0066] When the predetermined threshold is 0.1, in the collected data AD shown in Figure 8, 24°C, 26°C, and 27°C correspond to the first set temperature. Furthermore, since 24°C and 26°C correspond to the first set temperature, 23°C and 25°C, which are 1°C lower than these first set temperatures and have a change probability less than the predetermined threshold, correspond to the second set temperature. Therefore, when the predetermined threshold is 0.1 and the collected data AD to be processed is the collected data AD shown in Figure 8, the determination unit 304 determines that 23°C is the second set temperature to be set for the air conditioner 1, if the air conditioning performed by the air conditioner 1 is cooling.

[0067] Returning to the explanation of step SA301, if the determination unit 304 determines that the first condition is not met (step SA301: NO), it determines whether all of the set temperatures recorded in the collected data AD to be processed are the first set temperature or the third set temperature (step SA305). The third set temperature is a set temperature in which the corresponding change probability is less than a predetermined threshold. For example, in the example of collected data AD shown in Figure 3, 23°C and 24°C are the third set temperatures, and 24°C is the third set temperature. Since a temperature one level lower than the first set temperature of 25°C and with a change probability less than a predetermined threshold is determined to be the second set temperature, 24°C is determined to be both the second and third set temperature, and 23°C is determined to be the third set temperature.

[0068] If the determination unit 304 determines that all of the set temperatures recorded in the collected data AD to be processed are first set temperatures (step SA305: first set temperature), it determines the set temperature that will result in the highest comfort level of the air-conditioned space S from among the set temperatures included in the collected data AD to be processed as the set temperature to be set on the air conditioning unit 1 (step SA306).

[0069] Returning to the explanation of step SA305, if the determination unit 304 determines that all of the set temperatures recorded in the collected data AD to be processed are third set temperatures (step SA305: third set temperature), it determines the set temperature that results in the smallest energy savings for the air conditioner 1 from among the set temperatures included in the collected data AD to be processed as the set temperature to be set for the air conditioner 1 (step SA307).

[0070] The setting temperature that results in the lowest energy consumption of the air conditioner 1 among the set temperatures recorded in the collected data AD is the highest set temperature among the set temperatures recorded in the collected data AD when the operating mode of the air conditioner 1, as indicated by the operating mode information, is cooling. Conversely, when the operating mode of the air conditioner 1, as indicated by the operating mode information, is heating, it is the lowest set temperature among the set temperatures recorded in the collected data AD.

[0071] [3. Variant] (Variation 1) In the embodiment described above, the case of setting the set temperature and operating mode was explained for a single air conditioning unit 1. However, when multiple indoor units 11 of the air conditioning system 1 are installed in the same space, if there is a mix of indoor units 11 set to cooling mode and indoor units 11 set to heating mode, energy savings will not be achieved.

[0072] Therefore, among multiple air conditioning units 1 belonging to the same group ID, the air conditioning unit 1 to be configured is determined in advance. This air conditioning unit 1 to be configured is called the master unit, and other air conditioning units 1 that have the same organization ID and group ID as this master unit are called slave units. The server control device 30 refers to the record R of the air conditioning unit 1 of the master unit and sets the set temperature and operating mode. Then, when the server control device 30 sets the set temperature and setting mode of the air conditioning unit 1 of the master unit, it sets the set temperature and setting mode of the air conditioning unit 1 of the slave units to be the same as the set temperature and setting mode of the air conditioning unit 1 of the master unit.

[0073] In this modified example 1, the operating modes of multiple air conditioning units 1 set to the same group ID can be synchronized to either cooling or heating. For example, multiple air conditioning units 1 installed on the same floor can be set to the same operating mode. Therefore, heating or cooling can be efficiently performed on the floor where these multiple air conditioning units 1 are installed.

[0074] (Modification 2) Furthermore, although the above-described embodiment explained how to determine the set temperature and operating mode for the air conditioner 1, the airflow rate of the air blown out by the air conditioner 1 may also be set based on the difference between the room temperature and the set temperature. For example, if the difference between the room temperature data and the set temperature is 4°C or more, the airflow of the air conditioner 1 is set to "high". Furthermore, if the difference between the room temperature data and the set temperature is greater than 2°C but less than 4°C, the airflow of the air conditioner 1 is set to "medium". Furthermore, if the difference between the room temperature data and the set temperature is 2°C or less, the airflow of the air conditioner 1 is set to "low".

[0075] In this modified example 2, the server control device 30 includes an acquisition unit 302 and a determination unit 304 as functional units. The acquisition unit 302 acquires the room temperature of the air-conditioned space S. The determination unit 304 determines the set temperature to be set in the air conditioner 1 based on the number of changes stored in the server memory 310, and determines the airflow rate of the air conditioner 1 based on the difference between the determined set temperature and the room temperature acquired by the acquisition unit 302.

[0076] This allows the set temperature of the air conditioner 1 to be determined based on the number of times the set temperature has been changed, thereby setting the air conditioner 1 to a temperature that is less likely to cause discomfort to the user. Furthermore, the airflow of the air conditioner 1 is determined based on the difference between the determined set temperature and the acquired room temperature. As a result, the airflow of the air conditioner 1 can be controlled to be the optimal amount, improving user comfort and suppressing an increase in the energy consumption of the air conditioner.

[0077] [4. Effects of the Embodiments, etc.] As explained above, the air conditioning system 1000 is a system that air-conditions a space S using an air conditioning device 1, and includes a determination unit 304 that determines the optimal set temperature to be set in the air conditioning device 1, and an acquisition unit 303 that acquires environmental information of the space S. Based on the determined set temperature and the environmental information acquired by the acquisition unit 303, the determination unit 304 determines the operating mode of the air conditioning device 1. Therefore, the operating mode of the air conditioner 1 is determined based on the optimal set temperature determined by the determination unit 304 and the acquired environmental information, so that the air conditioner 1 can be operated in an operating mode that corresponds to the set temperature and environmental information. This suppresses a decrease in user comfort and suppresses an increase in energy consumption of the air conditioner 1 compared to when an operating mode that does not correspond to the environmental information is executed.

[0078] The acquisition unit 303 acquires the room temperature of the air-conditioned space S as environmental information, and the determination unit 304 determines whether to set the operating mode of the air conditioning unit 1 to cooling operation or heating operation based on the determined set temperature and the room temperature acquired by the acquisition unit 303. Therefore, the operating mode of the air conditioner 1 is determined to be either cooling or heating based on the set temperature and the room temperature of the conditioned space S acquired as environmental information by the acquisition unit 303. For example, if the set temperature is higher than the room temperature, the operating mode of the air conditioner 1 is determined to be heating, and if the set temperature is lower than the room temperature, the operating mode of the air conditioner 1 is determined to be cooling, thus setting the optimal operating mode corresponding to the set temperature and the room temperature of the conditioned space S. Therefore, a decrease in user comfort can be suppressed, and the increase in energy consumption of the air conditioner 1 can be suppressed compared to when an operating mode that does not correspond to environmental information is executed.

[0079] The determination unit 304 determines the operating mode of the air conditioner 1 to be heating operation if the determined set temperature is higher than the room temperature acquired by the acquisition unit 303, and determines the operating mode of the air conditioner 1 to be cooling operation if the determined set temperature is lower than the room temperature acquired by the acquisition unit 303. Therefore, the system can be set to an optimal operating mode corresponding to the set temperature and the room temperature of the air-conditioned space S. This suppresses a decrease in user comfort and reduces the increase in energy consumption of the air conditioner 1 compared to when an operating mode that does not correspond to environmental information is executed.

[0080] The air conditioning system according to Technical Reference 1, wherein the acquisition unit 303 acquires the room temperature of the air-conditioned space S as environmental information, and the determination unit 304 determines the airflow rate of the air conditioning device 1 based on the difference between the determined set temperature and the room temperature acquired by the acquisition unit 303.

[0081] Therefore, the airflow rate of the air conditioner 1 is determined based on the difference between the set temperature and the acquired room temperature. This shortens the time it takes for the air conditioner 1 to reach the set temperature, thereby suppressing a decrease in user comfort.

[0082] The server memory 310 stores the number of times the set temperature was set and the number of times the set temperature was changed for each set temperature of the air conditioner 1. The determination unit 304 determines the optimal set temperature to be set in the air conditioner 1, based on at least the number of setting cycles and the number of changes. Therefore, the optimal setting temperature is determined based on at least the number of times it has been set and the number of times it has been changed. For example, by determining the optimal setting temperature to be one that has been set many times and changed few times, it is possible to set the temperature to the user's preference, thereby suppressing a decrease in user comfort.

[0083] (Technology 6) The server memory 310 stores the number of times a time period and outside temperature have been set and the number of times they have been changed. The determination unit 304 identifies the number of setting cycles and the number of change cycles to refer to based on the target time for determining the optimal set temperature and the ambient temperature at that time, and determines the optimal set temperature based on the identified number of setting cycles and change cycles. Therefore, based on the set time and the ambient temperature at that time, the number of setting and change counts to be referenced are identified, and the optimal set temperature is determined based on the identified number of setting and change counts. As a result, the optimal set temperature can be determined based on the set time and the ambient temperature at that time, and the number of setting and change counts associated with them, thereby suppressing a decrease in user comfort.

[0084] The determination unit 304 determines the optimal set temperature based on the probability that the set temperature of the air conditioner 1 will be changed. Therefore, since the optimal set temperature is determined based on the probability that the set temperature of the air conditioner 1 will be changed, for example, by setting the optimal set temperature to a temperature at which the probability of the set temperature being changed is low, the probability of the user changing the set temperature can be reduced, and a decrease in user comfort can be suppressed.

[0085] [5. Other Embodiments] As described above, the above embodiments have been explained as examples disclosed in this application. However, the technology in this disclosure is not limited to these embodiments and can be applied to embodiments that have been modified, replaced, added, or omitted. Furthermore, it is possible to combine the components described in the above embodiments to create new embodiments. Therefore, other embodiments are described below as examples.

[0086] In the embodiment described above, the parameter for determining the set temperature to be set in the air conditioning system 1 includes the outside air temperature. In other embodiments, the parameter may include, instead of or in conjunction with the outside air temperature, the outside air humidity, the amount of solar radiation in a predetermined area including the location of facility H, the amount of precipitation in a predetermined area including the location of facility H, etc.

[0087] In other embodiments, the management server 3 may further store the update date and time when updating the number of actual changes or the number of modifications. In these other embodiments, the change probability may be calculated with priority given to updates with more recent update dates and times.

[0088] In the embodiment described above, the predetermined range indicated by the collected data AD is the range from 23°C to 27°C. However, this predetermined range is merely an example and may be the range of settable temperatures that the air conditioner 1 can set, or it may be the range within the settable temperature range that the air conditioner 1 can set that is expected to be set by the user.

[0089] In the embodiment described above, the multiple set temperatures included in the predetermined range indicated by the collected data AD are set temperatures in 1°C increments. In other embodiments, the increment of the set temperatures included in the predetermined range is not limited to 1°C, but may be, for example, 0.5°C increments.

[0090] In other embodiments, at least one of the functions of the acquisition unit 302, update unit 303, determination unit 304, and setting unit 305 may be executed not by the server control device 30, but by a control device that controls each part of the terminal device 2 or a control device that controls each part of the air conditioner 1 (for example, a communication device 14). In these other embodiments, the control devices that control each part of the terminal device 2 or the control devices that control each part of the air conditioner 1 correspond to "computers". Also in these other embodiments, a program for realizing at least one of the functions of the acquisition unit 302, update unit 303, determination unit 304, and setting unit 305, which is executed by a control device that controls each part of the terminal device 2 or the control device that controls each part of the air conditioner 1, corresponds to "program". Also in these other embodiments, the memory of the terminal device 2 or the air conditioner 1 may store the management data MD. Furthermore, if the control device that controls each part of the air conditioning unit 1 functions as the setting unit 305, the setting unit 305 sets the set temperature for the air conditioning unit 1 by controlling each part of the air conditioning unit 1. In other words, in this case, the setting unit 305 does not generate setting data SD.

[0091] In the embodiment described above, the management data MD stores the number of changes for each pair of time period and ambient temperature. In other embodiments, instead of storing the number of changes for each pair of time period and ambient temperature, the server memory 310 may store the number of changes for each set temperature for each time period. In this other embodiment, the determination unit 304 determines the set temperature based on the number of changes corresponding to the time period.

[0092] In the embodiment described above, the management data MD is configured to store the number of changes for each pair of time zone and ambient temperature. In another embodiment, instead of storing the number of changes for each set temperature, the server memory 310 may be configured to store the number of changes for each set temperature for each ambient temperature. In this other embodiment, the determination unit 304 determines the set temperature based on the number of changes corresponding to the ambient temperature.

[0093] In the embodiment described above, the set temperature is determined based on the time period including the current time and the number of changes that match the ambient temperature acquired by the acquisition unit 302. In other words, in the embodiment described above, the set temperature is determined based on the number of changes that match the current conditions. In other embodiments, the set temperature may also be determined by considering the number of changes that are close to the current conditions (for example, the number of changes of ±1°C relative to the ambient temperature acquired by the acquisition unit 302).

[0094] In the embodiment described above, when there are multiple second and third set temperatures, the setting temperature that maximizes the comfort of the air-conditioned space S is determined as the set temperature to be set. However, the setting temperature that minimizes the energy consumption of the air conditioning device 1 may also be determined as the set temperature to be set.

[0095] The server processor 300 may consist of a single processor or multiple processors. These processors may also be hardware programmed to implement the corresponding functional units. That is, these processors may consist of, for example, an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array).

[0096] The configuration of the management server 3 shown in Figure 2 is merely an example, and the specific implementation is not particularly limited. In other words, it is not necessarily required that hardware corresponding to each part be implemented individually; it is also possible to configure the system so that a single processor executes programs to realize the functions of each part. Furthermore, some of the functions realized by software in the above-described embodiment may be implemented by hardware, or vice versa.

[0097] The step units in the flowcharts shown in Figures 6 and 7 are divided according to the main processing content to facilitate understanding of the operation, and the operation is not limited by the way the processing units are divided or the names of the processing units. Depending on the processing content, it may be further divided into more step units. Alternatively, it may be divided so that one step unit contains even more processing. Furthermore, the order of the steps may be changed as appropriate, as long as it does not hinder the intent of this disclosure.

[0098] Since the embodiments described above are for illustrative purposes of the technology described herein, various modifications, substitutions, additions, omissions, etc., can be made within the scope of the claims or equivalents thereof.

[0099] (Note) Based on the above description of embodiments, the following technologies are disclosed.

[0100] (Technology 1) An air conditioning system that air-conditions a space to be air-conditioned using an air conditioning device, comprising: a determination unit that determines the optimal set temperature to be set in the air conditioning device; and an acquisition unit that acquires environmental information of the space to be air-conditioned, wherein the determination unit determines the operating mode of the air conditioning device based on the determined set temperature and the environmental information acquired by the acquisition unit.

[0101] With this configuration, the operating mode of the air conditioner is determined based on the optimal set temperature determined by the decision unit and the acquired environmental information. Therefore, the air conditioner can be operated in an operating mode that corresponds to the set temperature and environmental information. This suppresses a decrease in user comfort and also suppresses an increase in the energy consumption of the air conditioner compared to when an operating mode that does not correspond to the environmental information is executed.

[0102] (Technology 2) The air conditioning system according to Configuration 1, wherein the acquisition unit acquires the room temperature of the air-conditioned space as environmental information, and the determination unit determines whether to set the operating mode of the air conditioning device to cooling operation or heating operation based on the determined set temperature and the room temperature acquired by the acquisition unit.

[0103] With this configuration, the operating mode of the air conditioner is determined to be either cooling or heating based on the set temperature and the room temperature of the conditioned space acquired as environmental information by the acquisition unit. For example, if the set temperature is higher than the room temperature, the operating mode of the air conditioner is determined to be heating, and if the set temperature is lower than the room temperature, the operating mode of the air conditioner is determined to be cooling, thus setting the optimal operating mode corresponding to the set temperature and the room temperature of the conditioned space. Consequently, a decrease in user comfort can be suppressed, and the increase in energy consumption of the air conditioner can be suppressed compared to when an operating mode that does not correspond to environmental information is executed.

[0104] (Technology 3) The air conditioning system according to Technical Reference 2, wherein the determination unit determines the operating mode of the air conditioning system to heating operation if the determined set temperature is higher than the room temperature acquired by the acquisition unit, and determines the operating mode of the air conditioning system to cooling if the determined set temperature is lower than the room temperature acquired by the acquisition unit.

[0105] With this configuration, if the set temperature is higher than the room temperature, the air conditioner's operating mode is set to heating, and if the set temperature is lower than the room temperature, the air conditioner's operating mode is set to cooling. This allows the system to be set to the optimal operating mode corresponding to the set temperature and the room temperature of the conditioned space. As a result, a decrease in user comfort is suppressed, and the increase in energy consumption of the air conditioner is suppressed compared to when an operating mode that does not correspond to environmental information is executed.

[0107] In this configuration, the airflow rate of the air conditioner is determined based on the difference between the set temperature and the acquired room temperature. Therefore, the time it takes to reach the set temperature in the air conditioner can be reduced, thus suppressing a decrease in user comfort.

[0109] With this configuration, the optimal setting temperature is determined based on at least the number of times it has been set and the number of times it has been changed. For example, by determining the optimal setting temperature to be one that has been set many times and changed few times, the user's preferred setting temperature can be set, thus preventing a decrease in user comfort.

[0110] (Technology 6) The air conditioning system according to Technical Reference No. 5, wherein the storage unit stores the number of setting cycles and the number of changes for each set of time period and outside temperature, and the determination unit identifies the number of setting cycles and the number of changes to refer to based on the set of target time and outside temperature for that target time, and determines the optimal setting temperature based on the identified number of setting cycles and the number of changes.

[0111] According to this configuration, the number of setting and changing cycles to be referenced is identified based on the set of the target time and the ambient temperature at that time, and the optimal set temperature is determined based on the identified number of setting and changing cycles. Therefore, the optimal set temperature can be determined based on the number of setting and changing cycles associated with the target time and the ambient temperature at that time, thereby suppressing a decrease in user comfort.

[0112] (Technology 7) The air conditioning system according to any one of the technologies 1 to 4, wherein the determination unit determines the optimal set temperature based on the probability that the set temperature of the air conditioning device will be changed.

[0113] In this configuration, the optimal set temperature is determined based on the probability that the set temperature of the air conditioner will be changed. By setting the set temperature of the air conditioner to a temperature at which the probability of changing the set temperature is low, for example, the probability of users changing the set temperature can be reduced, thereby suppressing a decrease in user comfort.

[0114] (Technology 8) A method for controlling an air conditioning system that air-conditions a space to be air-conditioned using an air conditioning device, wherein a processor is instructed to perform a process of determining the optimal set temperature to be set in the air conditioning device and a process of acquiring environmental information of the space to be air-conditioned, and the determination process determines the operating mode of the air conditioning device based on the determined set temperature and the environmental information acquired by the acquisition process.

[0115] With this configuration, the operating mode of the air conditioner is determined based on the determined optimal set temperature and acquired environmental information, allowing the air conditioner to operate in an operating mode that corresponds to the set temperature and environmental information. This suppresses a decrease in user comfort and reduces the increase in energy consumption of the air conditioner compared to when an operating mode that does not correspond to the environmental information is executed.

[0116] (Technology 9) A program that causes a processor mounted on an information processing device to perform the following: a process to determine the optimal set temperature to be set in an air conditioning system that air-conditions a space to be air-conditioned; and a process to acquire environmental information of the space to be air-conditioned; wherein the determination process determines the operating mode of the air conditioning system based on the determined set temperature and the environmental information acquired by the acquisition process.

[0117] With this configuration, the operating mode of the air conditioner is determined based on the determined optimal set temperature and acquired environmental information, allowing the air conditioner to operate in an operating mode that corresponds to the set temperature and environmental information. This suppresses a decrease in user comfort and reduces the increase in energy consumption of the air conditioner compared to when an operating mode that does not correspond to the environmental information is executed.
