[Modes for carrying out the invention] 【0010】 (Knowledge and other information that formed the basis of this disclosure) At the time the inventors conceived this disclosure, there was a technology in which a management server determined the optimal set temperature based on the outside temperature and the history of past temperature setting changes, and then set that temperature for the air conditioner. Generally, in the use of air conditioners, there is a trade-off between energy saving performance (hereinafter, energy saving may be abbreviated as "energy saving") and comfort. However, the inventors discovered that with conventional technology, the user's demands regarding energy saving performance and comfort were not reflected in the air conditioner settings. In order to solve this problem, the inventors came to constitute the subject matter of this disclosure. 【0011】 Therefore, this disclosure provides an air conditioning system, control method, and program that can reflect user requirements regarding energy-saving performance and comfort in their settings. 【0012】 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. 【0013】 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. 【0014】 (Embodiment 1) [1-1. Structure] [1-1-1. Configuration of the air conditioning system] FIG. 1 is a diagram showing the configuration of the air conditioning system in Embodiment 1. As shown in FIG. 1, the air conditioning system 1000 is a system that air - conditions the conditioned space S by the air conditioner 1. The air - conditioning of the conditioned space S includes cooling, heating, dehumidification, air supply, ventilation, etc. In this embodiment, the case where the air conditioner 1 cools and heats the conditioned space S will be described. The conditioned space S is a space owned by the facility H and is a space to be air - conditioned by the air conditioner 1. Note that the facility H may be, for example, a house, an office, a store (including the backyard), a medical facility, a public facility, etc. 【0015】 The air conditioning system 1000 includes the air conditioner 1. In the example of FIG. 1, the air conditioning system 1000 includes four or more air conditioners 1. Note that the number of air conditioners 1 included in the air conditioning system 1000 is not limited to four or more and may be less than four. The air conditioner 1 includes an indoor unit 11 and an outdoor unit 12. The air conditioner 1 performs air - conditioning operation by the indoor unit 11 and the outdoor unit 12 and air - conditions the conditioned space S where the indoor unit 11 is installed. The air conditioner 1 is connected to the network NW and communicates with devices connected to the network NW. The network NW is a communication network composed of a public line network, a dedicated line, the Internet, or other communication networks. 【0016】 The air conditioning system 1000 includes the terminal device 2. The terminal device 2 is a terminal used by the administrator P who manages the facility H. Note that the administrator P is not limited to a person and may be a subject having the management authority of the facility H (for example, a company operating the facility H). This administrator P is an example of a user. 【0017】 In the example of FIG. 1, the terminal device 2 is a laptop computer, but it may also be a tablet computer, a desktop computer, or a smartphone. The terminal device 2 is connected to the network NW. The terminal device 2 displays information related to the air conditioner 1 such as power consumption for each facility H. Further, the terminal device 2 performs various setting inputs to the management server 3 based on the operation of the administrator P. 【0018】 The air conditioning system 1000 includes a management server 3. The management server 3 is a server device that manages the air conditioner 1. The management server 3 is connected to the network NW and performs information processing with the air conditioner 1 and the terminal device 2 as clients. Note that the management server 3 may be a server device owned by the administrator P or a server device not owned by the administrator P. 【0019】 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 weather server 4 at least includes a forecast value of the outside air temperature of the facility H. For example, the weather data provided by the weather server 4 includes the measured values from the past (a few hours ago) to the present and the predicted values for the future (a few hours later) of the outside air temperature, humidity, wind direction, wind speed, and weather conditions of a predetermined area associated with the location information of the facility H such as the address and postal code of the facility H. Note that the weather server 4 may calculate and provide the pinpoint weather data of the facility H from the location information of the facility H. 【0020】 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 each constituted by a single device. For example, the management server 3 and the weather server 4 may be constituted by including a plurality of server devices with different processing contents, or may be constituted by the same server device. 【0021】 [1-1-2. Configuration of the air conditioner 1] Referring to Figure 1, the configuration of the air conditioning system 1 will be described. The air conditioning system 1 comprises an indoor unit 11, an outdoor unit 12, a remote control 13, and a communication device 14. Note that the number of indoor units 11 and outdoor units 12 in the air conditioning system 1 may be multiple. 【0022】 The indoor unit 11 and the outdoor unit 12 are connected by refrigerant piping and control wiring. Thus, in the air conditioning system 1, the indoor unit 11 and the outdoor unit 12 constitute a refrigerant cycle. 【0023】 The remote control 13 is installed on a wall or the like in the air-conditioned space S. The remote control 13 has multiple operation buttons for the user of the air conditioner 1 to start or stop operation, operate menus, use cursor keys, etc. The remote control 13 also has a display panel that displays, for example, the set temperature of the air conditioner 1 and the operating status of the indoor unit 11. 【0024】 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 the set temperature of the air conditioning unit 1 is changed, the communication device 14 sends operation data RD to the management server 3. 【0025】 Operation data RD is data indicating that an operation to change the set temperature has been received. Operation data RD records the air conditioner ID (Identification), date and time of change, type of air conditioner, set temperature before change, and set temperature after change. 【0026】 The air conditioner ID is the identification information for air conditioning unit 1. The change date and time is the date and time when the set temperature of air conditioning unit 1 was changed. The air conditioning type is the type of air conditioning performed by air conditioning unit 1, and in this embodiment, it indicates cooling or heating. The set temperature before change is the set temperature of air conditioning unit 1 before the change. The set temperature after change is the set temperature of air conditioning unit 1 after the change. 【0027】 Furthermore, the operation data RD also includes information showing the operating history of the air conditioning system 1 during heating and cooling until the set temperature is changed. Specifically, the operation data RD includes the operating time of heating and cooling at the set temperature before the change, and the amount of energy (power consumption) consumed by the indoor unit 11 and outdoor unit 12, etc., during that operating time. 【0028】 The communication device 14 receives configuration data SD from the management server 3. The configuration data SD contains configuration information related to the air conditioning of the air conditioning unit 1. For example, the configuration data SD is data that instructs the setting of the temperature of the air conditioning unit 1, and the temperature to be set in the air conditioning unit 1 is recorded. The communication device 14 operates the air conditioning unit 1 based on the received configuration data SD. For example, the communication device 14 operates the air conditioning unit 1 at the temperature recorded in the configuration data SD. Details of the configuration of the communication device 14 will be described later. 【0029】 [1-1-3. Configuration of Management Server 3] Figure 2 shows an example of the configuration of the management server 3 in Embodiment 1. As shown in Figure 2, the management server 3 comprises a server control device 30 and a server communication device 31. 【0030】 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 interface circuits to which other devices and sensors are connected. 【0031】 Server memory 310 is memory that stores programs and data. Server memory 310 stores control programs 311, management database 312, user request information 313, and data to be processed by the server processor 300. Server memory 310 has a non-volatile storage area. Server memory 310 may also have a volatile storage area and constitute the work area of ​​the server processor 300. Server memory 310 is composed of, for example, ROM (Read Only Memory) or RAM (Random Access Memory). 【0032】 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 contains the air conditioner ID, communication information, location of facility H, type of air conditioning, current set temperature, and management data. 【0033】 The communication information is information for communicating with the air conditioning unit 1, for example, the address information of the communication device 14. The location of facility H is the location of facility H where the air conditioning unit 1 is installed, for example, the address of facility H. The current set temperature is the set temperature set on the air conditioning unit 1. 【0034】 The management data is data used to manage the operating performance of the air conditioning unit 1 during heating and cooling. Specifically, the management data includes information related to changes in the set temperature of the air conditioning unit 1. 【0035】 Figure 3 shows an example of management data in Embodiment 1. As shown in Figure 3, the management data MD records time periods in one-hour increments from 0:00 to 23:59. More specifically, the management data MD records time periods from N:00 to N:59 for each of the 0:00 to 23:00 time periods. Here, N is an integer from 0 to 23. 【0036】 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. Note that 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. 【0037】 The management data MD records one collection data AD for each pair of time period and outside temperature. The collection data AD contains information related to the history of changes in the set temperature of the air conditioner 1. The collection data AD collects various data within a predetermined range of the set temperature. The set temperature to be set on the air conditioner 1 is determined from the predetermined range of the set temperature indicated by the collection data AD by the processing of the flowchart described later. 【0038】 The collected data AD records the set temperatures of multiple air conditioners 1 in 1°C increments within a predetermined range. In the example in Figure 3, the collected data AD records 23°C, 24°C, 25°C, 26°C, and 27°C. In other words, in the example in Figure 3, the predetermined range of set temperatures shown in the collected data AD is 23°C to 27°C. 【0039】 The collected data AD records the number of actual settings, the number of changes, and the probability of change for each recorded set temperature. In other words, the collected data AD is an example of the set temperature change history. In the example in Figure 3, the collected data AD records the number of actual settings, the number of changes, and the probability of change for each of the following temperatures: 23°C, 24°C, 25°C, 26°C, and 27°C. 【0040】 The "actual count" indicates the number of times the corresponding set temperature was set to air conditioner 1. The "number of changes" indicates the number of times the corresponding set temperature was changed to another set temperature. The "probability of changes" indicates the probability that the corresponding set temperature was changed to another set temperature. The probability of changes is calculated, for example, by dividing the corresponding number of changes by the corresponding actual count. 【0041】 Furthermore, the management data MD also includes information on the amount of energy consumed by the air conditioning unit 1 during heating and cooling, based on the information contained in the operation data RD. Specifically, the management data MD includes the date and time when the set temperature was changed, the operating time of heating and cooling at the previous set temperature, and the amount of energy consumed (power consumption) during that operating time. 【0042】 User request information 313 is information about user requests entered by the user via the input unit 306. User request information 313 includes user requests regarding the energy-saving performance and comfort of the air conditioning system 1 during heating and cooling. Note that energy-saving performance and comfort are in a trade-off relationship with each other. Therefore, as for the energy-saving performance and comfort of the air conditioning system 1 during heating and cooling, user request information 313 includes user requests for at least one of energy-saving performance and comfort. For example, user request information 313 includes information regarding user requests for at least one of energy-saving performance and comfort, associated with the air conditioner ID that identifies the air conditioning system 1. 【0043】 The energy-saving performance of the air conditioning system 1 during heating and cooling refers to the extent to which it can operate with reduced energy consumption compared to the standard amount of energy consumed during conventional heating and cooling operation. For example, energy-saving performance can be expressed as an energy saving rate, which is the percentage (%) of energy saved compared to the standard energy consumption during heating and cooling. 【0044】 The comfort level of the air conditioning system 1 during heating and cooling refers to the degree of comfort felt by users in the conditioned space S when the system is operated at the temperature set by the management server 3. For example, if users in the conditioned space S feel comfortable, they will not have any complaints about the set temperature and will therefore not change it. Conversely, if users in the conditioned space S feel uncomfortable, they will change the set temperature due to their dissatisfaction. Therefore, one indicator of the degree of comfort felt by users in the conditioned space S is the number of times the management server 3 changes the set temperature. As an example of this indicator, a higher number of temperature changes indicates discomfort, while a lower number of temperature changes indicates comfort. 【0045】 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. The server communication device 31 communicates with the air conditioner 1, the terminal device 2, and the weather server 4 according to the control of the server control device 30. 【0046】 The server processor 300 functions as a communication control unit 301, acquisition unit 302, update unit 303, determination unit 304, setting unit 305, and input unit 306 by reading and executing the control program 311 stored in the server memory 310. 【0047】 The communication control unit 301 communicates with the air conditioning unit 1, the terminal unit 2, and the weather server 4 via the server communication device 31. 【0048】 The acquisition unit 302 acquires the outside air temperature. The acquisition unit 302 processes one record R and acquires the outside air 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 information requesting a forecast value of the outside air temperature for a time period including the current time, and it records 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 records the time period from H hours and 0 minutes to H+1 hours and 0 minutes. Note that H is an integer from 0 to 24, and M is an integer from 0 to 59. 【0049】 When the communication control unit 301 receives 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 ​​corresponding to the location and time period of 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. In this embodiment, when the acquisition unit 302 calculates the average value of the forecast values, it either truncates the decimal part or rounds it to the nearest whole number. 【0050】 The update unit 303 updates the management DB 312. Every hour at L minutes, the update unit 303 updates the actual count recorded in the collected data AD. 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 update of the actual count, every hour at L minutes, 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 set of outside temperature and degree acquired by the acquisition unit 302. Then, the update unit 303 increments the actual count corresponding to the currently set temperature recorded in the record R to be processed from the actual count recorded in the identified collected data AD. The update unit 303 also updates the change probability corresponding to the incremented actual count to a change probability that reflects the actual count after the increment. 【0051】 Now, with reference to Figure 4, we will explain how to update the actual count. Figure 4 is a diagram illustrating how to update the actual count in Embodiment 1. 【0052】 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. 【0053】 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". 【0054】 Next, the update of the update unit 303 will be explained. When the communication control unit 301 receives operation data RD, the update unit 303 updates the management DB 312 based on the received operation data RD. The update unit 303 identifies the record R containing the air conditioner ID of the received operation data RD from the management DB 312. Then, the update unit 303 updates the current set temperature of the identified record R to the changed set temperature recorded in the received operation data RD. The update unit 303 also updates the air conditioner type of the identified record R to the air conditioner type recorded in the received operation data RD. 【0055】 Furthermore, the update unit 303 causes the acquisition unit 302 to acquire the outside air temperature based on the record R identified by the received operation data RD. Next, 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. 【0056】 Next, the update unit 303 refers to the received operation data RD and increments the number of changes recorded in the identified collected data AD that corresponds to the pre-change setting temperature recorded in the received operation data RD. 【0057】 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. 【0058】 Furthermore, the update unit 303 stores information regarding the amount of energy consumed by the air conditioning unit 1 during heating and cooling, which is included in the operation data RD, in the record R identified from the air conditioner ID of the received operation data RD. Specifically, the update unit 303 stores in the record R the date and time when the set temperature was changed, the operating time of heating and cooling at the previous set temperature, and the amount of energy consumed (power consumption) during that operating time. 【0059】 Now, with reference to Figure 5, we will explain how to update the number of changes. Figure 5 is a diagram illustrating how to update the number of changes in Embodiment 1. 【0060】 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. In Figure 5, the update unit 303 identifies the collected data AD corresponding to the 2 PM hour and the outside temperature of 34°C from the management data MD recorded in the record R to be processed. 【0061】 In the explanation of Figure 5, an example is given where the pre-change setting temperature recorded in the received operation data RD is 25°C. Also in the explanation of Figure 5, an example is given where the post-change setting temperature recorded in the received operation data RD is 24°C. 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. In addition, 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. 【0062】 Returning to the explanation of Figure 2, the determination unit 304 determines the set temperature to be set in the air conditioner 1. Details of the determination method of the determination unit 304 will be described later. 【0063】 The setting unit 305 sets the set temperature determined by the determination unit 304 to the air conditioner 1. The setting unit 305 sets the set temperature to the air conditioner 1 based on the record R to be processed. More specifically, the setting unit 305 generates setting data SD 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. The generated setting data SD contains the set temperature determined by the determination unit 304. 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. 【0064】 The input unit 306 is a processing unit that receives input from administrator P via the server communication device 31 to the terminal device 2. Specifically, for each air conditioning unit 1, the input unit 306 receives administrator P's requests regarding the energy-saving performance and comfort of the air conditioning unit 1 during heating and cooling via the operation screen of the terminal device 2. The input unit 306 records the administrator P's requests for the air conditioning unit 1 received in this way in the user request information 313, associating them with the air conditioner ID of the air conditioning unit 1. 【0065】 For example, the input unit 306 receives the target energy saving rate from the administrator P as an indicator of the energy-saving performance of the air conditioning unit 1 during heating and cooling, and records it in the user request information 313. The input unit 306 also receives the number of changes to the target set temperature (number of changes per day) from the administrator P as an indicator of the comfort level of the air conditioning unit 1 during heating and cooling, and records it in the user request information 313. 【0066】 [1-2. Operation] Next, the operation of each part of the air conditioning system 1000 according to Embodiment 1 will be described. Figure 6 is a flowchart showing an example of the operation of the management server 3 in Embodiment 1. 【0067】 The flowchart in Figure 6 is a flowchart performed for each air conditioning unit 1. In other words, the flowchart in Figure 6 is an operation performed for each record R stored in the management DB 312. 【0068】 As shown in Figure 6, the input unit 306 receives input from administrator P regarding the energy-saving performance and comfort of the air conditioning system 1 during heating and cooling via the terminal device 2 (S1). The input unit 306 records the requests received from administrator P in user request information 313. In Embodiment 1, the target energy saving rate for the air conditioning system 1 during heating and cooling is received from administrator P and recorded in user request information 313. 【0069】 Next, the acquisition unit 302 acquires the outside temperature based on the record R to be processed (S2). The process for acquiring the outside temperature (S2) will be described in detail. 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 will contain time periods such as 10:00 to 11:00, 11:00 to 12:00, 12:00 to 1:00, etc. Note that the time periods included in the forecast value request information are, as an example, up to 8 hours in the future from the current time. 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, a forecast value for 10:00 and a forecast value for 11:00) corresponding to the location and time of 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 for each time period and acquires the calculated average value as the outside temperature. For example, the acquisition unit 302 acquires the outside temperature for the time period from 10:00 to 11:00 by averaging the forecast value for 10:00 and the forecast value for 11:00. 【0070】 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 (S3). The process for identifying the collection data AD (S3) will be described in detail. The determination unit 304 identifies the collection data AD corresponding to each time period and the set of outside temperature and temperature acquired in S2 from the management data MD recorded in the record R to be processed. 【0071】 Next, the determination unit 304 performs a determination process (S4). The determination process is the process of determining the set temperature to be set for the air conditioner 1 for each time period. In the determination process, the collected data AD identified in S3 is the target of processing. 【0072】 The decision process (S4) will be described in detail. In the decision process, the decision unit 304 reads the change probability for the set temperature from the collected data AD corresponding to the set temperature pair. Then, the decision unit 304 identifies a set temperature for which the change probability satisfies a predetermined criterion. 【0073】 Here, the determination unit 304 uses a value corresponding to the administrator P's request recorded in the user request information 313 as a criterion for determining the set temperature. Specifically, the determination unit 304 replaces the target energy saving rate, target number of changes, etc., which are input as administrator P's requests regarding energy saving performance and comfort, with the corresponding change probability. 【0074】 In Embodiment 1, the system receives the target energy saving rate from the administrator P. The determination unit 304 then refers to table data showing the correspondence between the energy saving rate and the change probability, and replaces the target energy saving rate with the corresponding change probability. This table data showing the correspondence with the change probability is created in advance based on past performance of the target facility or similar facilities, or simulations. For example, if the target energy saving rate is low, the comfort level, which is in a trade-off relationship, will be high. Therefore, the probability of changing the set temperature corresponding to the target energy saving rate will be low. Conversely, if the energy saving rate is high, the comfort level, which is in a trade-off relationship, will be low. Therefore, the probability of changing the set temperature corresponding to the target energy saving rate will be high. 【0075】 The determination unit 304 identifies the set temperature from the collected data AD, using the change probability corresponding to the target energy saving rate as a reference (threshold). For example, the determination unit 304 identifies a set temperature that has been changed infrequently by the user, i.e., a set temperature below a predetermined threshold. The determination unit 304 also records the change probability used as the reference (threshold) to identify the set temperature as an actual value in the management data MD. 【0076】 Based on the probability of changing the set temperature corresponding to the target energy saving rate described above, for example, during cooling, the higher the target energy saving rate, the higher the set temperature the determination unit 304 will determine. Conversely, during heating, the higher the target energy saving rate, the lower the set temperature the determination unit 304 will determine. 【0077】 Next, the determination unit 304 identifies the setting temperature among the identified setting temperatures that will result in the lowest energy consumption (energy saving) during operation of the air conditioner 1. Specifically, the determination unit 304 sets the highest temperature among the identified setting temperatures as the setting temperature during cooling, and conversely, sets the lowest temperature among the identified setting temperatures as the setting temperature during heating. In the determination process (S4), the above process is performed for each time period to determine the setting temperature for each time period. 【0078】 Figure 7 illustrates the case in Embodiment 1 where the user selects the target energy saving rate. Figure 7 shows an example of determining the set temperature for cooling the air conditioner 1 during the 8-10 o'clock period when the outside temperature is 30.0°C. 【0079】 The input unit receives the administrator P's requests (targets) regarding the energy-saving performance of the air conditioning unit 1 during cooling via the operation screen of the terminal device 2. As shown in Figure 7, the administrator P, as a user, inputs the target energy-saving rate (10%, 15%, 20%, etc.) via the operation screen of the terminal device 2. As a result, the target energy-saving rate (10%, 15%, 20%, etc.) is recorded in the user request information 313. This input from administrator P corresponds to the processing of S1 described above (see Figure 6). 【0080】 The determination unit 304 replaces the target energy saving rate (10%, 15%, 20%, etc.) entered by the administrator P with the corresponding probability of changing the set temperature (5%, 10%, 15%, etc.). The determination unit 304 uses the replaced change probability as a reference (threshold) to determine the set temperature. 【0081】 For example, if the target energy saving rate is 10%, the determination unit 304 sets the probability of changing the corresponding set temperature to 5%. Then, using this 5% change probability as a threshold, the determination unit 304 identifies set temperatures below the threshold from among the candidate set temperatures at an outside temperature of 30.0°C (...25.5°C, 26.0°C, 26.5°C, 27.0°C, 27.5°C...). In the illustrated example, 26.0°C and 25.5°C are identified. Then, the determination unit 304 decides that 26.0°C, the highest of the identified set temperatures, is the set temperature. 【0082】 Furthermore, the determination unit 304 sets the probability of changing the corresponding set temperature to 10% if the target energy saving rate is 15%. Then, the determination unit 304 uses this 10% change probability as a threshold and identifies set temperatures below the threshold from among the candidate set temperatures at an outside temperature of 30.0°C (...25.5°C, 26.0°C, 26.5°C, 27.0°C, 27.5°C...). In the illustrated example, 26.5°C, 26.0°C, and 25.5°C are identified. Then, the determination unit 304 decides that 26.5°C, the highest of the identified set temperatures, is the set temperature. 【0083】 Furthermore, the determination unit 304 sets the probability of changing the corresponding set temperature to 15% if the target energy saving rate is 20%. Then, the determination unit 304 uses this 15% change probability as a threshold and identifies set temperatures below the threshold from among the candidate set temperatures at an outside temperature of 30.0°C (...25.5°C, 26.0°C, 26.5°C, 27.0°C, 27.5°C...). In the illustrated example, 27.0°C, 26.5°C, 26.0°C, and 25.5°C are identified. Then, the determination unit 304 decides that 27.0°C, the highest of the identified set temperatures, is the set temperature. 【0084】 Next, the setting unit 305 sets the determined set temperature for each time period to the air conditioner 1 (S5). Specifically, the setting unit 305 notifies the air conditioner 1 via the communication control unit 301 of the set data SD, which is a set of the outside air temperature and the set temperature for each time period. 【0085】 Furthermore, at the beginning of the day (for example, at midnight), the management server 3 may obtain the setting data SD for a full day's worth of time periods (midnight to 4 AM, 4 AM to 8 AM, 8 AM to 12 PM, etc.) through the operations described above, and then notify the air conditioning unit 1 of the average of all the time period settings as the setting for the full day. 【0086】 [1-3. Effects, etc.] As described above, in the air conditioning system 1000, the input unit 306 receives input from the administrator P regarding at least one of the energy-saving performance of the air conditioning unit 1 and the comfort of the air-conditioned space S when air conditioning the space S. When the determination unit 304 determines the set temperature of the air conditioning unit 1 based on the change history of the set temperature of the air conditioning unit 1, it determines the set temperature based on the criteria corresponding to the administrator P's received request. 【0087】 According to this, in the air conditioning system 1000, the set temperature of the air conditioning unit 1 is determined based on criteria that correspond to the requirements of the administrator P regarding at least one of the energy-saving performance of the air conditioning unit 1 and the comfort of the air-conditioned space S. Therefore, the air conditioning system 1000 can reflect the user's requirements regarding energy-saving performance and comfort in its settings. 【0088】 Furthermore, the input unit 306 receives the target energy saving rate for the air conditioning system 1. The determination unit 304 selects a set temperature from among the candidate set temperatures such that the probability of changing the set temperature based on the change history satisfies the threshold change probability corresponding to the received energy saving rate. 【0089】 According to this, the air conditioning system 1000 can determine the set temperature of the air conditioner 1 so as to satisfy the energy saving rate targeted by the administrator P. In other words, the air conditioning system 1000 can reflect the energy saving rate targeted by the administrator P in the set temperature of the air conditioner 1. 【0090】 (Embodiment 2) Next, Embodiment 2 will be described. 【0091】 [2-1. Structure] The configuration of each part of the air conditioning system 1000 in Embodiment 2 is the same as the configuration of each part of the air conditioning system 1000 in Embodiment 1, and a detailed explanation thereof will be omitted as appropriate. 【0092】 [2-2. Operation] Next, the operation of each part of the air conditioning system 1000 in Embodiment 2 will be described. Embodiment 2 differs from Embodiment 1 in that it receives requests from the administrator P regarding comfort rather than energy-saving performance during heating and cooling of the air conditioning device 1. Specifically, in Embodiment 2, at S1 in Figure 6, the input unit 306 receives from the administrator P the number of changes to the target set temperature (number of changes per day). Note that the target number of changes is not limited to the number of changes per day, but may be, for example, the number of changes per time period. 【0093】 In Embodiment 2, the determination unit 304 refers to table data showing the correspondence between the number of changes per day and the probability of change, and replaces the target number of changes per day with the corresponding probability of change. This table data showing the correspondence with the probability of change is created in advance based on past performance of the target facility or similar facilities, or simulations. For example, if the target number of changes per day is small, the probability of change will be low, and therefore the probability of change for the corresponding set temperature will be low. Conversely, if the target number of changes per day is large, the probability of change will be high, and therefore the probability of change for the corresponding set temperature will be high. 【0094】 The determination unit 304 identifies the set temperature from the collected data AD, using the change probability corresponding to the target number of changes per day as a criterion (threshold). For example, the determination unit 304 identifies set temperatures that have been changed infrequently by users, i.e., set temperatures below a predetermined threshold. 【0095】 Based on the change probability corresponding to the target number of changes per day mentioned above, for example, during cooling, the decision unit 304 will determine a lower set temperature as the target number of changes decreases. Conversely, during heating, the decision unit 304 will determine a higher set temperature as the target number of changes decreases. 【0096】 Figure 8 illustrates the case in Embodiment 2 where the user selects the target number of changes. Figure 8 shows an example of determining the set temperature for cooling the air conditioner 1 during the 8-10 o'clock period when the outside temperature is 30.0°C. 【0097】 As shown in Figure 8, administrator P, acting as a user, enters the target number of changes per day (0.5 changes / day, 1 change / day, 2 changes / day, etc.). As a result, the user request information 313 records the target number of changes per day (0.5 changes / day, 1 change / day, 2 changes / day, etc.). 【0098】 The decision unit 304 replaces the target number of changes per day entered by the administrator P (0.5 times / day, 1 time / day, 2 times / day, etc.) with the corresponding probability of changing the set temperature (5%, 10%, 20%, etc.). The decision unit 304 uses the replaced probability of change as a reference (threshold) to determine the set temperature. 【0099】 For example, if the target number of changes per day is 0.5 times / day, the determination unit 304 sets the probability of changing the corresponding set temperature to 5%. Then, using this 5% change probability as a threshold, the determination unit 304 identifies set temperatures below the threshold from among the candidate set temperatures at an outside temperature of 30.0°C (...25.5°C, 26.0°C, 26.5°C, 27.0°C, 27.5°C...). In the illustrated example, 26.0°C and 25.5°C are identified. Then, the determination unit 304 decides that 26.0°C, the highest of the identified set temperatures, is the set temperature. 【0100】 Furthermore, the determination unit 304 sets the probability of changing the corresponding set temperature to 10% if the target number of changes per day is 1. Next, the determination unit 304 uses this 10% change probability as a threshold and identifies set temperatures below the threshold from among the candidate set temperatures at an outside temperature of 30.0°C (...25.5°C, 26.0°C, 26.5°C, 27.0°C, 27.5°C...). In the illustrated example, 26.5°C, 26.0°C, and 25.5°C are identified. Next, the determination unit 304 decides that 26.5°C, the highest of the identified set temperatures, is the set temperature. 【0101】 Furthermore, the determination unit 304 sets the probability of changing the corresponding set temperature to 20% if the target number of changes per day is 2. Next, the determination unit 304 uses this 20% change probability as a threshold and identifies set temperatures below the threshold from among the candidate set temperatures at an outside temperature of 30.0°C (...25.5°C, 26.0°C, 26.5°C, 27.0°C, 27.5°C...). In the illustrated example, 27.0°C, 26.5°C, 26.0°C, and 25.5°C are identified. Next, the determination unit 304 decides that 27.0°C, the highest of the identified set temperatures, is the set temperature. 【0102】 [2-3. Effects, etc.] As described above, in Embodiment 2, the input unit 306 receives the number of times the target set temperature in the air conditioner 1 has been changed. The determination unit 304 selects a set temperature from among the candidate set temperatures such that the probability of changing the set temperature based on the change history satisfies a threshold for the change probability corresponding to the number of changes received. 【0103】 According to this, the air conditioning system 1000 can determine the set temperature of the air conditioner 1 in such a way that it satisfies the number of temperature changes required by the administrator P, which is the target level of comfort. In other words, the air conditioning system 1000 can reflect the comfort level targeted by the administrator P in the set temperature of the air conditioner 1. 【0104】 (Embodiment 3) Next, Embodiment 3 will be described. 【0105】 [3-1. Structure] The configuration of each part of the air conditioning system 1000 in Embodiment 3 is the same as the configuration of each part of the air conditioning system 1000 in Embodiment 1, and a detailed explanation thereof will be omitted as appropriate. 【0106】 [3-2. Operation] Next, the operation of each part of the air conditioning system 1000 in Embodiment 3 will be described. Embodiment 3 differs from Embodiment 1 in that it presents the past performance of the air conditioning device 1 to the administrator P and accepts user requests regarding energy-saving performance and comfort based on that performance. 【0107】 Specifically, in Embodiment 3, at S1 in Figure 6, the input unit 306 presents the past performance of the air conditioning system 1 to the administrator P via the terminal device 2. Then, the input unit 306 receives user requests regarding energy-saving performance and comfort based on the presented past performance. 【0108】 Figure 9 is a flowchart showing an example of the operation in Embodiment 3, which involves presenting results and receiving user input. Specifically, the flowchart for operations S11 to S13 shown in Figure 9 corresponds to the process of S1 described above (see Figure 6). Therefore, after the flowchart shown in Figure 9, the processes of S2 to S5 described above are executed. As shown in Figure 9, the input unit 306 reads the management DB 312 and identifies the record R of the air conditioning unit 1 to be configured (S11). 【0109】 Next, the input unit 306 reads the past performance of the air conditioning system 1 regarding energy-saving performance and comfort (for example, the performance for the previous month) from the management data MD of the identified record R. Specifically, the input unit 306 reads from the management data MD for the most recent month, including the operating time of heating and cooling at the outside air temperature, the amount of energy consumed during that operating time (power consumption), information on the operation of changing the set temperature, and the change probability used as a criterion (threshold) to determine the set temperature. 【0110】 The input unit 306 presents to the administrator P via the operation screen of the terminal device 2, etc., the past performance of the air conditioner 1 read out regarding energy saving performance and comfort (S12). Specifically, the input unit 306 compares the amount of energy consumed as a standard at a predetermined outside air temperature with the actual performance of the air conditioner 1 (cooling and heating operation time and the amount of energy consumed during that operation time) to calculate the actual value of the energy saving rate and present it to the administrator P. The input unit 306 also calculates the number of temperature change operations per unit time from the information on temperature change operations and presents it to the administrator P. In addition, the input unit 306 calculates the average of the change probability used as a standard (threshold) to identify the temperature and presents it to the administrator P. Since energy saving performance and comfort are in a trade-off relationship, the past performance presented by the input unit 306 only needs to be at least one of energy saving performance or comfort. 【0111】 Next, the input unit 306 receives input from administrator P regarding past performance in terms of energy-saving performance and comfort via the terminal device 2 (S13). For example, the input unit 306 presents administrator P with options such as "emphasize energy-saving performance," "emphasize comfort," and "continue as in past performance" in relation to past performance in terms of energy-saving performance and comfort. Administrator P inputs the user's request regarding past performance by selecting the desired option from the presented options. 【0112】 Figure 10 is a diagram illustrating the case in Embodiment 3 where performance data is presented and user input is performed. As shown in Figure 10, the input unit 306 displays the past performance data (previous month's performance) of the air conditioner 1 regarding energy saving performance and comfort on the operation screen G1 of the terminal device 2 and presents it to the administrator P. Specifically, the input unit 306 displays the energy saving rate, the average number of temperature setting changes (monthly), and the change probability set to the standard (threshold) adopted by the management server 3 as the previous month's performance data of the air conditioner 1 on the operation screen G1. 【0113】 Next, the input unit 306 presents administrator P with options regarding the previous month's performance. Specifically, the input unit 306 presents administrator P with options such as "same as last month" if the performance is the same as last month, options to be more energy-efficient than last month's performance, and options to be more comfortable than last month's performance. For example, options to be more energy-efficient than last month's performance include "I want to slightly increase the energy saving rate" and "I want to try harder to save energy." Also, options to be more comfortable than last month's performance include "I want to make it a little more comfortable" and "I want to prioritize comfort more." The input unit 306 records the options received from administrator P in user request information 313. 【0114】 In Embodiment 3, at S4 in Figure 6, the determination unit 304 uses the change probability corresponding to the request (choice) of administrator P recorded in user request information 313 as a criterion for determining the set temperature. 【0115】 For example, if the administrator P's request (option) is "similar to this month's performance" (same as the previous month), the decision unit 304 sets the same 10% as the previous month as the baseline (threshold). Also, if the administrator P's request (option) is more energy-saving, such as "I want to slightly increase the energy saving rate" or "I want to work harder on energy saving," the decision unit 304 sets the baseline (threshold) to 15% and 20%, respectively. Furthermore, if the administrator P's request (option) is more comfort-oriented, such as "I want to make it a little more comfortable" or "I want to prioritize comfort more," the decision unit 304 sets the baseline (threshold) to 7% and 5%, respectively. 【0116】 [3-3. Effects, etc.] As described above, in Embodiment 3, when the input unit 306 receives a request from the administrator P, it presents past performance data for at least one of the energy-saving performance of the air conditioning unit 1 and the comfort of the air-conditioned space S, based on the management data MD of the air conditioning unit 1. 【0117】 According to this, in the air conditioning system 1000, when the administrator P inputs their requests regarding at least one of the energy-saving performance of the air conditioning device 1 and the comfort of the air-conditioned space S, past performance regarding energy-saving performance and comfort can be checked. 【0118】 Furthermore, the input unit 306 accepts input from administrator P regarding past performance data presented. 【0119】 According to this, administrator P can easily set energy-saving performance and comfort levels based on past performance. 【0120】 (Other embodiments) As described above, Embodiments 1 to 3 have been explained as examples disclosed in this application. However, the technology in this disclosure is not limited thereto and can be applied to embodiments that have been modified, replaced, added, or omitted. Furthermore, it is possible to combine the components described in Embodiments 1 to 3 to create new embodiments. Therefore, other embodiments are described below as examples. 【0121】 In embodiments 1 to 3 described above, the user input received by the input unit 306 via the server communication device 31 was exemplified as input from administrator P from terminal device 2. In other embodiments, the user input received by the input unit 306 via the server communication device 31 may be from the remote control 13 of the air conditioner 1. Specifically, the input unit 306 may be configured to receive input from the operation screen of the remote control 13 via the communication device 14 and the server communication device 31. 【0122】 In embodiments 1 to 3 described above, the configuration includes the outside air temperature as a parameter for determining the set temperature to be set in the air conditioning system 1. In other embodiments, the configuration 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. 【0123】 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. 【0124】 In embodiments 1 to 3 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. 【0125】 In embodiments 1 to 3 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. 【0126】 In other embodiments, the terminal device 2 may be configured to perform operations related to the management server 3. Specifically, the terminal device 2 comprises a control device corresponding to the server control device 30, a storage device corresponding to the server memory 310, and a communication device corresponding to the server communication device 31. The control device of the terminal device 2 provides the functions of the communication control unit 301, acquisition unit 302, update unit 303, determination unit 304, setting unit 305, and input unit 306 described above. In this case, the control device of the terminal device 2 corresponds to a "computer," and the program executed by the control device of the terminal device 2 corresponds to a "program." Furthermore, regarding the control of the air conditioning system 1, instead of the communication device 14, one of the indoor unit 11, outdoor unit 12, or remote control 13 may be configured to have the functions of the communication device 14 described above. 【0127】 In embodiments 1 to 3 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 these other embodiments, the determination unit 304 determines the set temperature based on the number of changes corresponding to the time period. 【0128】 In embodiments 1 to 3 described above, the management data MD is configured to store the number of changes for each pair of time zone and ambient temperature. In other embodiments, 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. 【0129】 In embodiments 1 to 3 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 embodiments 1 to 3 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 a number of changes close to the current conditions (for example, a number of changes of ±1°C relative to the ambient temperature acquired by the acquisition unit 302). 【0130】 The program executed by the management server 3, etc., in this embodiment is provided as an installable or executable file recorded on a computer-readable recording medium such as an optical recording medium like a DVD (Digital Versatile Disk), a USB memory, or a semiconductor memory device like an SSD (Solid State Disk). Alternatively, the program may be stored on a computer connected to a network such as the Internet and provided or distributed by downloading it via the network. Furthermore, the program may be pre-installed in ROM or the like. 【0131】 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 claims or their equivalents. 【0132】 (Note) Based on the above description of embodiments, the following technologies are disclosed. 【0133】 (Technology 1) An air conditioning system that air-conditions a space to be air-conditioned using an air conditioning device, comprising: an input unit that receives input from a user regarding at least one of the energy-saving performance of the air conditioning device and the comfort of the space to be air-conditioned when air-conditioning the space; and a determination unit that determines the set temperature to be set on the air conditioning device based on criteria corresponding to the received user request when determining the set temperature to be set on the air conditioning device.
