FIG. 2 shows the overall configuration of the air conditioning management system of this embodiment. The air conditioning management system includes an air conditioner 1, a controller 2, a home gateway 3, a center server 4, and an information server 5. The controller 2 and the center server 4 constitute an air conditioning management device that manages the air conditioning device 1 that varies the temperature of the space H.

The air conditioner 1 is installed in a space H (for example, a floor in a building, each room, or a wide public area) where the air conditioning environment is managed by this system. The air conditioner 1 and the controller 2 are connected to the home network NT1. The home network NT1 is connected to the Internet NT2 via the home gateway 3, and the center server 4 and the information server 5 are on the Internet NT2. Exists. The home network NT1 may use any of power line carrier communication, communication using a LAN cable, communication using a dedicated cable, and wireless communication.

Fig. 1 shows the block configuration of the air conditioning management system. In FIG. 1, the home gateway 3 is omitted.

The air conditioner 1 has a function of an air conditioner that changes the temperature (thermal environment) of the space H. That is, the air conditioner 1 is configured to vary the temperature of the space H. The air conditioner 1 includes an operation unit 1a, and an operation state (operation / stop), a target temperature, and the like are set by a user operating the operation unit 1a. Further, the air conditioner 1 is also set to run / stop, target temperature, etc. by remote control by the controller 2. The air conditioner 1 also has a function of transmitting information on actual operation history (history of operation / stop, target temperature, etc.) to the controller 2. That is, the air conditioner 1 is configured to transmit information (operation information) indicating its own operation state (operation / stop, target temperature, etc.) to the controller 2. Therefore, the air conditioner 1 transmits an operation history that is a history of operation information of the air conditioner 1 to the controller 2.

The controller 2 includes a device controller 2a, a receiver 2b, and a transmitter 2c.

The device control unit 2a is connected to the home network NT1 and remotely controls the air conditioner 1 by operating / stopping the air conditioner 1 and setting a target temperature.

The receiving unit 2b is connected to the home network NT1 and receives information from the air conditioner 1. This receiving part 2b comprises the driving history acquisition part. That is, the receiving unit 2b functions as an operation history acquisition unit that acquires an operation history that is a history of operation information of the air conditioner 1.

The transmission unit 2 c is connected to the home network NT 1 and transmits information to the center server 4 via the home gateway 3.

The center server 4 includes a reception unit 4a, a storage timing control unit 4b, a storage unit 4c, an algorithm generation unit 4d, and a device control unit 4e.

The receiving unit 4a receives information from the controller 2 and the information server 5 via the Internet NT2.

The storage timing control unit 4b sets the timing for storing various information in the storage unit 4c.

The storage unit 4c stores various information.

The algorithm generation unit 4d creates a control algorithm for setting the operation / stop timing of the air conditioner 1 and the target temperature, and the device control unit 4e transmits the control algorithm (operation algorithm) to the controller 2.

Next, the operation of this air conditioning management system will be described.

First, the air conditioner 1 transmits past operation history information (each history of operation / stop, target temperature, etc.) to the controller 2. The driving history information is information indicating the driving history. That is, the air conditioner 1 transmits an operation history that is a history of operation information to the controller 2. The transmission timing of this operation history information (operation information) is, for example, when the settings (operation / stop, target temperature) of the air conditioner 1 are manually set by operating the operation unit 1a at regular intervals. In addition, information on the installation location of the air conditioner 1 (living room, kitchen, etc.) is added to the operation history information. For example, the operation information includes an installation location of the air conditioner 1, an operation state (operation / stop), and a target temperature.

In the controller 2, the receiving unit 2 b acquires the operation history information from the air conditioner 1, and the transmission unit 2 c transmits the operation history information to the center server 4. In the center server 4, the receiving unit 4 a acquires operation history information from the controller 2.

The information server 5 stores environmental information (external temperature, humidity, etc.) related to the weather including the location of the space H as needed, and the receiving unit 4a of the center server 4 acquires environmental information from the information server 5. In this way, the receiving unit 4a acquires an environmental history that is a history of environmental information. The environmental information indicates an environmental state that is the state of the environment (inside the space H or outside the space H). The environmental state is a value indicating the state of the environment, and is, for example, a temperature inside the space H, a temperature outside the space H (outside air temperature), a humidity inside the space H, and a humidity outside the space H. That is, the information server 5 constitutes an environment detection unit that detects environment information indicating the state of the environment inside or outside the space H, and the reception unit 4a of the center server 4 is configured to detect the environment inside or outside the space H. An environment information acquisition unit is configured to acquire an environment history that is an environment information history indicating the environment state.

The operation history information is added with a time stamp indicating the time for each event such as operation / stop of the air conditioner 1, operation such as changing the target temperature, or operation state change. That is, the driving information indicates the driving state at a certain time. Therefore, the driving history is time-series data of driving states.

The environment information has a time stamp indicating the measurement time such as outside temperature and humidity. That is, the environmental information indicates the environmental state at a certain time. Therefore, the environmental history is time-series data of environmental conditions.

Then, the storage timing control unit 4b of the center server 4 determines at which time each information is stored in the storage unit 4c based on each time stamp of the operation history information and the environment information. That is, the storage timing control unit 4b associates the driving information with the environmental information based on the time based on the driving history and the environmental history. For example, the storage timing control unit 4b acquires driving information indicating the driving state at the time closest to the predetermined time from the driving history, and acquires environmental information indicating the environmental state at the time closest to the predetermined time from the environmental history. The acquired driving information (driving state) and environmental information (environmental state) are associated with each other. And the memory | storage timing control part 4b memorize | stores the combination of the driving | operation information and environmental information mutually matched on the basis of time in the memory | storage part 4c. This time includes, for example, a predetermined time every day, a time when the air conditioner 1 is operated by the user (operation / stop operation time, target temperature changing operation time), and the presence / absence of a person in the space H. There is a time when the absence state changes (using a human detection means timing (not shown)).

The storage timing control unit 4b sequentially stores the operation history information and environment information at each time (or in the vicinity of each time) determined as described above in association with each other in the storage unit 4c. Accordingly, the storage unit 4c stores a combination of driving information and environmental information associated with each other based on the time based on the driving history and the environmental history. That is, in the storage unit 4c, operation history information and environment information at each time determined by the storage timing control unit 4b are stored in association with each other in a time series as shown in FIG. FIG. 3 is a table format in which time, operation history (operation information), and environment information correspond to each other, and the operation history includes the installation location of the air conditioner 1, the on / off state of the air conditioner 1 (operation / stop state), Each item of the target temperature of the air conditioner 1 is included.

Then, the algorithm generation unit 4d of the center server 4 periodically determines the optimal control algorithm of the air conditioner 1 based on each information stored in the storage unit 4c, and updates the control algorithm.

In the present embodiment, the algorithm generation unit 4d generates an operation algorithm that defines an environmental state condition (change condition) for changing the operation state of the air conditioner 1.

The operation algorithm includes a first algorithm (operation change algorithm) that defines an environmental state condition (operation change condition) for changing the operation state of the air conditioner 1, and an environmental state for setting the target temperature of the air conditioner 1. And a second algorithm (temperature setting algorithm) for defining the above condition (temperature setting condition).

The operation change algorithm defines an operation of changing the operation state of the air conditioner 1 when the current state of the environment satisfies the operation change condition. Here, the operation change condition includes a condition (operation condition) for switching the air conditioner 1 from stop to operation and a condition (stop condition) for switching the air conditioner 1 from operation to stop.

That is, the operation change algorithm defines an operation of changing the operation state of the air conditioner 1 from stop to operation when the current state of the environment satisfies the operation condition. The operating condition is that the current state of the environment is the first environmental state. When the environmental state is the outside air temperature, the operating condition is that the current outside air temperature is equal to or higher than the ON temperature.

The first environmental state (on temperature) is determined by the environmental state (outside temperature) when the operation state of the air conditioner 1 is changed from the stop to the operation. For example, the algorithm generation unit 4d obtains an average of the environmental state with respect to the environmental information associated with the time when the operation state of the air conditioner 1 is changed from the stop to the operation based on the operation history and the environment history. Is selected as the first environmental state. In short, the average of the environmental state (outside air temperature) when the operation state of the air conditioner 1 is changed from the stop to the operation is adopted as the ON temperature.

Also, the operation change algorithm defines an operation of changing the operation state of the air conditioner 1 from operation to stop when the current state of the environment satisfies the stop condition. The stop condition is that the current state of the environment becomes the second environment state. When the environmental state is the outside air temperature, the stop condition is that the current outside air temperature is less than the off temperature.

The second environmental state (off temperature) is determined by the environmental state (outside temperature) when the operation state of the air conditioner 1 is changed from operation to stop. For example, the algorithm generation unit 4d obtains the average of the environmental state for the environmental information associated with the time when the operating state of the air conditioner 1 is changed from driving to stop based on the driving history and the environmental history, and the environmental state Is selected as the second environmental state. In short, the average of the environmental state (outside temperature) when the operating state of the air conditioner 1 changes from operation to stop is adopted as the off temperature.

The temperature setting condition is a condition for setting the target temperature of the air conditioner 1 to a target temperature (set temperature) according to the current state of the environment.

That is, the temperature setting algorithm defines an operation of setting the target temperature of the air conditioner 1 to a set temperature corresponding to the temperature setting condition when the current state of the environment satisfies the temperature setting condition. The temperature setting condition is that the current state of the environment becomes a predetermined state. When the environmental state is an outside air temperature, the temperature setting condition is that the current outside air temperature is included in a predetermined range.

The set temperature is determined by the operation state (target temperature) of the operation information associated with the environment information whose environmental state is the predetermined state. For example, the algorithm generation unit 4d obtains an average of the target temperatures for the operation information associated with the environmental information whose environmental state is a predetermined state, and selects the average of the target temperatures as the set temperature. In short, the average of the target temperatures in the operation information associated with the environmental information whose environmental state is the predetermined state is adopted as the set temperature.

FIG. 4 is a flowchart showing control algorithm creation processing by the algorithm generation unit 4d. Here, outside air temperature is used as environmental information (environmental state). Further, the air conditioner 1 performs a cooling operation in summer.

First, the algorithm generation unit 4d reads data in a predetermined period from the storage unit 4c to the current time (S1).

Next, the algorithm generation unit 4d classifies the data read from the storage unit 4c for each installation location of the air conditioner 1 (S2), and starts an estimation process for each installation location (S3).

And the algorithm production | generation part 4d is the outside air temperature (on temperature) Ton when the air conditioner 1 starts an operation based on the history of the outside air temperature when the operation / stop state of the air conditioner 1 is switched from the stop to the operation. Is statistically estimated (S4). That is, the algorithm generation unit 4d uses the operation information and the environment information as the operation information that satisfies the predetermined (first) operation condition (the operation / stop state of the air conditioner 1 has been switched from stop to operation). Extract the corresponding environmental information (outside temperature). And the algorithm production | generation part 4d determines the parameter (outside temperature Ton) used by an operation | movement algorithm based on the extracted environmental state (outside temperature).

For example, the history of the outside air temperature when the operation / stop state of the air conditioner 1 is switched from the stop to the operation is Ta1, Ta2,. . . , Tan, Ton = (Ta1 + Ta2 + ... + Tan) / N. That is, the average value of the outside air temperature when the operation / stop state of the air conditioner 1 is switched from the stop to the operation is the outside air temperature Ton.

Next, the algorithm generation unit 4d determines the outside air temperature (off temperature) Toff when the air conditioner 1 is stopped based on the history of the outside air temperature when the operation / stop state of the air conditioner 1 is switched from operation to stop. Statistical estimation is performed (S5). That is, the algorithm generation unit 4d satisfies the predetermined (second) operation condition (the operation / stop state of the air conditioner 1 has been switched from operation to stop) based on the extracted operation information and environment information. Extract environmental information (outside temperature) corresponding to driving information. And the algorithm production | generation part 4d determines the parameter (outside temperature Toff) used by an operation | movement algorithm based on the extracted environmental state (outside temperature).

For example, the history of the outside air temperature when the operation / stop state of the air conditioner 1 is switched from operation to stop is Tb1, Tb2,. . . , Tbn, Toff = (Tb1 + Tb2 + ... + Tbn) / N. That is, the average value of the outside air temperature when the operation / stop state of the air conditioner 1 is switched from the operation to the stop is the outside air temperature Toff.

Next, the algorithm generation unit 4d statistically sets a target temperature (set temperature) Tm to be set when the air conditioner 1 is in operation, corresponding to the outside temperature based on the history of the target temperature and the outside temperature. Estimate (S6). That is, the algorithm generation unit 4d extracts driving information (target temperature) corresponding to environmental information whose environmental state (outside air temperature) is a predetermined state (predetermined value) based on the driving information and the environmental information. And the algorithm production | generation part 4d determines the parameter (target temperature Tm) used with an operation | movement algorithm based on driving | operation information (target temperature).

For example, the history of the target temperature of the air conditioner 1 when the outside air temperature is the predetermined value Td1 is Te1, Te2,. . . , Ten, Tma = (Te1 + Te2 + ... + Ten) / N. That is, the average value of the target temperatures when the outside air temperature is Td1 is the target temperature Tm (Tma) corresponding to the outside air temperature Td1.

Similarly, the average value of the target temperature when the outside air temperature is the predetermined value Td2 is set as the target temperature Tm (Tmb) corresponding to the outside air temperature Td2, and the average value of the target temperature when the outside air temperature is the predetermined value Td3. As the target temperature Tm (Tmc) corresponding to the outside air temperature Td3, the target temperature Tm is obtained for each outside air temperature.

That is, the algorithm generation unit 4d averages one or more target temperatures having the same environmental state (outside temperature) based on the operation history (target temperature) and the environment information (outside temperature), and this averaging An operation algorithm using the target temperature is generated. In other words, the algorithm generation unit 4d obtains an average of the target temperature for the operation information associated with the environmental information whose environmental state (outside temperature) is a predetermined state (predetermined value), and operates using the average of the target temperature. Generate an algorithm.

Then, the algorithm generation unit 4d determines whether or not the processing of steps S3 to S6 has been completed for all installation locations (S7). If the processes in steps S3 to S6 have not been completed for all the installation locations, the process returns to step S3, the installation locations are changed, and the above-described processing is repeated. When the processes of steps S3 to S6 are completed for all the installation locations, the process of this flowchart is terminated.

And the algorithm production | generation part 4d is the outside temperature (on temperature) Ton when the air conditioner 1 starts operation, the outside temperature (off temperature) Toff when the air conditioner 1 stops, the target temperature for each outside temperature (setting) Based on each estimation result of (temperature) Tm, an optimal control algorithm (operation algorithm) of the air conditioner 1 is determined.

For example, FIG. 5 is an example of a control algorithm determined by the algorithm generation unit 4d.

The outside air temperature (on temperature) Ton when the air conditioner 1 starts operation and the outside temperature (off temperature) Toff when the air conditioner 1 stops are both the outside air temperature T1. That is, if the current outside air temperature (the current state of the environment) is less than the outside air temperature T1, the air conditioner 1 stops, and if the current outside air temperature is equal to or higher than the outside air temperature T1, the air conditioner 1 operates. Note that the current outside air temperature is obtained from the information server 5. When T1 ≦ outside air temperature (current outside air temperature) <T2, the target temperature of the air conditioner 1 is set to the target temperature Tm12. When T2 ≦ outside air temperature (current outside air temperature), the target temperature of the air conditioner 1 is set. Is set to the target temperature Tm11 (<Tm12). The target temperature Tm12 is a target temperature Tm obtained for an outside air temperature of T1 or more and less than T2, and the target temperature Tm11 is a target temperature Tm obtained for an outside air temperature of T2 or more.

The device control unit 4e transmits this control algorithm to the controller 2. The device control unit 2a of the controller 2 performs remote control of the air conditioner 1 by operating / stopping the air conditioner 1, setting a target temperature, and the like based on this control algorithm.

Further, the controller 2 may present the control algorithm to the user with an image or the like, and prompt the manual operation of the air conditioner 1 according to the control algorithm.

Moreover, as environmental information, in addition to the outside air temperature, indoor and outdoor humidity or the like may be used, and the outside air temperature and humidity may be used in combination.

And this control algorithm is regularly updated, and the optimal control algorithm reflecting the usage of the user can always be used.

As described above, in the present embodiment, air conditioning control corresponding to the usage for each user can be performed in correspondence with the external environment. Therefore, in this system, the comfort of the air-conditioning environment suitable for the user can be realized in consideration of the outdoor environment.

In addition, although the average value calculation was used for deriving the outside air temperature Ton, the outside air temperature Toff, and the target temperature Tm, it may be derived using the least square method. That is, the average of the target temperatures may be obtained by an arithmetic mean or may be obtained by using a least square method.

Further, the algorithm generation unit 4d may statistically estimate the boundary value of the outside air temperature at which the target temperature is switched based on the target temperature and the history of the outside air temperature.

The receiving unit 4a of the center server 4 acquires the operation history information of the air conditioners 1 in the spaces H1 to H3. The receiving unit 4a acquires the environment information of the spaces H1 to H3 from the information server 5. .

That is, in the present embodiment, the receiving unit 4a configures an operation history acquisition unit that acquires the operation history of the corresponding air conditioner 1 for each space H (H1 to H3). The receiving unit 4a constitutes an environment information acquiring unit that acquires a corresponding environment history for each space H (H1 to H3).

The storage unit 4c of the center server 4 stores driving history information and environment information at each time determined by the storage timing control unit 4b in association with each other in time series for each of the spaces H1 to H3. That is, the storage unit 4c is configured to store, for each space H, a combination of driving information and environmental information associated with each other with respect to time. Here, outside temperature is used as environmental information.

The algorithm generation unit 4d obtains an average of the target temperatures for the operation information associated with the environmental information whose environmental state is the predetermined state for each space H. Next, the algorithm generation unit 4d classifies the plurality of spaces H (H1 to H3) into a plurality of groups based on a comparison between the target temperature average and a predetermined threshold value. Next, the algorithm generation unit 4d generates an operation algorithm for each group.

FIG. 9 is a flowchart showing a control algorithm creation process by the algorithm generation unit 4d of the center server 4.

In this flowchart, each of the spaces H1 to H3 (home, etc.) is “a high setting group that tends to set the target temperature higher”, “a standard setting group that tends to set the target temperature as standard”, “ It is determined which of the “low setting group that tends to set the target temperature low” belongs. Note that the air conditioner 1 performs a cooling operation in summer.

First, the algorithm generation unit 4d reads all data in the spaces H1 to H3 in a predetermined period from the storage unit 4c to the current time (S11).

Next, based on the operation history information and the environment information read in step S11, the algorithm generation unit 4d determines target temperatures for grouping from one or more target temperatures when the outside air temperature is the same. A threshold value is determined (S12).

That is, the algorithm generating unit 4d selects the driving information associated with the environmental information in which the environmental state is the predetermined state with respect to the driving history of each of the plurality of spaces H1 to H3, and based on the target temperature indicated by the selected driving information. To determine a predetermined threshold.

For example, in the spaces H1 to H3, the history of the target temperature at the outside air temperature Tf1 is Tg1, Tg2,. . . , Tgn (where Tg1 <Tg2 <... <Tgn). At this time, the threshold value K1 for distinguishing the high setting group from the standard setting group at the outside air temperature Tf1 is K1 = (Tg1 + 2Tgn) / 3. In the outside air temperature Tf1, the threshold value K2 for distinguishing between the standard setting group and the low setting group is K2 = (2Tg1 + Tgn) / 3.

Next, the algorithm generation unit 4d averages one or a plurality of target temperatures when the outside air temperature is the same for each of the spaces H1 to H3 based on the operation history information and the environment information read in step S11. . Then, the algorithm generator 4d compares the target temperature Tmx averaged for each outside air temperature with the threshold values K1 and K2 for each of the spaces H1 to H3, and groups each of the spaces H1 to H3 for each outside air temperature. (S13). As described above, the algorithm generation unit 4d converts the plurality of spaces H (H1 to H3) into a plurality of groups (high setting group, standard setting group, low setting group) based on the comparison between the average of the target temperatures and the predetermined threshold values K1 and K2. Classification).

That is, the space H where the target temperature Tmx> K1 at the outside air temperature Tf1 belongs to the high setting group at the outside air temperature Tf1. In addition, at the outside air temperature Tf1, the space H where K2 <target temperature Tmx ≦ K1 belongs to the standard setting group at the outside air temperature Tf1. Further, at the outside air temperature Tf1, the space H where the target temperature Tmx ≦ K2 belongs to the low setting group at the outside air temperature Tf1.

Specifically, in the space H1, the history of the target temperature at the outside air temperature Tf1 is 18 ° C., 19 ° C., 20 ° C., and 21 ° C. In the space H2, the history of the target temperature at the outside air temperature Tf1 is 22 ° C., 23 ° C., 24 ° C., and 25 ° C. In the space H3, the history of the target temperature at the outside air temperature Tf1 is 26 ° C., 27 ° C., 28 ° C., and 29 ° C. That is, in the spaces H1 to H3, the target temperature history at the outside air temperature Tf1 is 18 ° C., 19 ° C., 20 ° C., 21 ° C., 22 ° C., 23 ° C., 24 ° C., 25 ° C., 26 ° C., 27 ° C., 28 ° C. 29 ° C.

At this time, the threshold value K1 for distinguishing the high setting group from the standard setting group is K1 = (18 + 2 × 29) /3=25.3° C. The threshold value K2 for distinguishing between the standard setting group and the low setting group is K2 = (2 × 18 + 29) /3=21.7° C.

Since the history of the target temperature at the outside air temperature Tf1 in the space H1 is 18 ° C., 19 ° C., 20 ° C., and 21 ° C., the target temperature Tmx in the space H1 averaged at the outside air temperature Tf1 = 19.5 ° C. It becomes. Therefore, the space H1 becomes the target temperature Tmx (19.5 ° C.) <K2 (21.7 ° C.), and becomes a low setting group at the outside air temperature Tf1.

Further, since the history of the target temperature at the outside air temperature Tf1 in the space H2 is 22 ° C., 23 ° C., 24 ° C., and 25 ° C., the target temperature Tmx of the space H2 averaged at the outside air temperature Tf1 = 23.5 ° C. It becomes. Therefore, the space H2 becomes K2 (21.7 ° C.) <Target temperature Tmx (27.5 ° C.) <K1 (25.3 ° C.), and becomes a standard setting group at the outside air temperature Tf1.

Further, since the history of the target temperature at the outside air temperature Tf1 in the space H3 is 26 ° C., 27 ° C., 28 ° C., and 29 ° C., the target temperature Tmx in the space H3 averaged at the outside air temperature Tf1 is 27.5 ° C. Become. Therefore, the space H3 becomes the target temperature Tmx (27.5 ° C.)> K1 (25.3 ° C.), and becomes a high setting group at the outside air temperature Tf1.

Next, for each group, the algorithm generation unit 4d averages one or more target temperatures when the outside air temperature is the same based on the operation history information and the environment information read in step S11. That is, the algorithm generation unit 4d derives a target temperature (set temperature) Tm (Tmy) for each outside air temperature in each group (S14). That is, the algorithm generation unit 4d obtains an average of the target temperatures (that is, the set temperature Tm) for the operation information associated with the environmental information whose environmental state is the predetermined state for each group.

As described above, the algorithm generation unit 4d classifies each space H into one of the high setting group, the standard setting group, and the low setting group for each outside air temperature, and the target temperature (set temperature) for each outside air temperature in each group. Tmy is set.

Further, the algorithm generation unit 4d statistically calculates the outside air temperature Ton when the air conditioner 1 starts operation and the outside air temperature Toff when the air conditioner 1 stops for each of the high setting group, the standard setting group, and the low setting group. (S15). The process of estimating the outside air temperature Ton when the air conditioner 1 starts operation and the outside air temperature Toff when the air conditioner 1 stops are also performed by an averaging process for each group.

Then, the algorithm generation unit 4d instructs the operation of the air conditioner 1 using the target temperature Tmy for each outside air temperature in each group estimated as described above, the outside air temperature Ton at the start of operation, and the outside air temperature Toff at the time of stop. A motion algorithm is generated for each group.

For example, FIG. 10 is an example of a control algorithm (operation algorithm) determined by the algorithm generation unit 4d. In FIG. 10, Y1 is a control algorithm for the high setting group, and Y2 is a control algorithm for the low setting group.

In the control algorithm Y1 of the high setting group, the outside air temperature (on temperature) Ton when the air conditioner 1 starts operation and the outside temperature (off temperature) Toff when the air conditioner 1 stops are both the outside air temperature T11. . That is, if the current outside air temperature is less than the outside air temperature T11, the air conditioner 1 stops, and if the current outside air temperature is equal to or higher than the outside air temperature T11, the air conditioner 1 starts operation. When T11 ≦ outside air temperature (current outside air temperature) <T12, the target temperature of the air conditioner 1 is set to the target temperature Tm22. When T12 ≦ outside air temperature, the target temperature of the air conditioner 1 is set to the target temperature Tm21 (< Tm22). The target temperature Tm22 is a target temperature (set temperature) Tm obtained for an outside air temperature of T11 or more and less than T12, and the target temperature Tm21 is a target temperature (set temperature) obtained for an outside air temperature of T12 or more. Tm.

In the control algorithm Y2 for the low setting group, the outside air temperature (on temperature) Ton when the air conditioner 1 starts operation and the outside temperature (off temperature) Toff when the air conditioner 1 stops are both the outside temperature T21. . That is, if the current outside air temperature is lower than the outside air temperature T21, the air conditioner 1 stops, and if the current outside air temperature is equal to or higher than the outside air temperature T21, the air conditioner 1 starts operation. When T21 ≦ outside air temperature (current outside air temperature) <T22, the target temperature Tm32 of the air conditioner 1 is set. When T22 ≦ outside air temperature (current outside air temperature), the target temperature Tm31 (< Tm32). The target temperature Tm32 is a target temperature (set temperature) Tm obtained for an outside air temperature of T21 or more and less than T22, and the target temperature Tm31 is a target temperature (set temperature) obtained for an outside air temperature of T22 or more. Tm.

Here, target temperature Tm21> target temperature Tm31, target temperature Tm22> target temperature Tm32, T11> T21, and T12> T22 are set.
