The second communication unit 13B is an IF for connecting the adapter 13 to the communication network 5 in communication. The control unit 13D controls the indoor unit 12 with AI (artificial intelligence ). Each indoor unit 12 is provided with an adapter 13. The storage unit 13C includes: an operation record memory 131C, a failure estimation model 132C, and a refrigerant amount estimation model 133C.
The operation record memory 131C periodically collects various operation state data collected from the main body 11A of the outdoor unit 11 and the main body 12A of the indoor unit 12 using the first communication unit 13A, and stores the collected operation state data. The second communication unit 13B transmits the operation state data stored in the operation record memory 131C to the server 3. The server 3 uses the operation state data of the air conditioner 2 as training data, and generates a refrigerant amount estimation model and a failure estimation model based on the training data, which will be described in detail later. Further, the server 3 transmits the generated refrigerant quantity estimation model and the generated failure estimation model to the adapter 13 via the communication network 5. The adapter 13 receives the refrigerant quantity estimation model 133C and the failure estimation model 132C from the server 3 using the second communication unit 13B, and stores the received refrigerant quantity estimation model 133C and failure estimation model 132C in the storage unit 13C.

The failure estimation model 132C can estimate a failure of the air conditioner 2, for example, an abnormality related to fouling of the outdoor heat exchanger, locking of the expansion valve, or deterioration of the compressor.
The refrigerant amount estimation model 133C estimates the current remaining refrigerant amount in the refrigerant circuit, not shown, in the main body 11A of the outdoor unit 11 and the main body 12A of the indoor unit 12 by inputting partial operation state data collected from the main body 11A of the outdoor unit 11 and the main body 12A of the indoor unit 12. For example, the refrigerant quantity estimation model 133C estimates the current refrigerant quantity remaining in the refrigerant circuit using at least the rotation speed of the compressor, the refrigerant discharge temperature of the compressor, the heat exchanger temperature, the opening degree of the expansion valve, and the outside air temperature in the operation state data indicating the operation state at the time of operation. As a result, the refrigerant quantity presumption model 133C can presume an abnormality caused by the shortage of the refrigerant quantity.

Next, the operation of the air conditioning system 1 of the present embodiment will be described. Fig. 10 is an explanatory diagram showing an example of the processing operation of the air conditioning system 1 from the start of the test operation request to the completion of the maintenance operation. The server 3 notifies the smartphone terminal 4 of the user of the air conditioner 2 corresponding to the preset rule of the commissioning request at the preset timing (step S1). The preset timing is a timing of issuing a trial operation request, for example, a timing of once a day. The preset time is not limited to once a day, and may be changed to once every two days or once every three days, for example. The preset rule is a condition for grouping the air conditioners 2 for which the maintenance worker 6 is responsible for in a preset period, and is, for example, a condition for specifying the air conditioners 2 of a group corresponding to setting region information indicating a setting region for identifying the arrangement position of the air conditioners 2 and the number information indicating the number of air conditioners 2.
When receiving the test operation request, the smartphone terminal 4 displays a test operation request screen 43A shown in fig. 8 on the display unit 43. The user of the smartphone terminal 4 can check the commissioning request screen 43A and confirm the commissioning request of the air conditioner 2. Then, the smartphone terminal 4 requests the air conditioner 2 to start the test operation in response to the test operation start operation on the test operation request screen 43A (step S2). The air conditioner 2 performs the test operation in response to the test operation start request. When the air conditioner 2 performs the test operation, the server 3 is notified of the test operation result (step S3). Further, when the air conditioner 2 performs the test operation and an abnormality of the air conditioner 2 is estimated using the refrigerant amount estimation model 133C or the failure estimation model 132C, for example, the abnormality content is acquired as a test operation result.
The server 3 receives the test operation result from the air conditioner 2, and notifies the maintenance recommendation to the smartphone terminal 4 when the received content is the content indicating that the air conditioner 2 is estimated to be abnormal (step S4). Upon receiving the maintenance recommendation from the server 3, the smartphone terminal 4 displays a maintenance recommendation screen 43B shown in fig. 9. The user of the smartphone terminal 4 can view the maintenance recommendation screen 43B and confirm the maintenance recommendation of the air conditioner 2. The smartphone terminal 4 displays a maintenance reservation screen 43C shown in fig. 9 in accordance with the maintenance recommendation operation on the maintenance recommendation screen 43B. The user of the smartphone terminal 4 can view the maintenance reservation screen 43C and input reservation contents of the maintenance job.
The smartphone terminal 4 transmits a maintenance reservation request to the server 3 in accordance with the maintenance reservation operation on the maintenance reservation screen 43C (step S5). When receiving the maintenance reservation request from the smartphone terminal 4, the server 3 notifies the maintenance worker 6 of the maintenance request according to the maintenance reservation content (step S6). Further, since the maintenance request is generated after the request for the trial operation only from the smartphone terminal 4 of the air conditioner 2 of the preset rule at the preset timing described above, the maintenance recommendation received at the same time in the intermediate period can be distributed and concentrated, that is, the maintenance request based on the trial operation result can be distributed by distributing the time of the trial operation of the air conditioner 2. Then, the maintenance worker 6 performs a maintenance operation of the air conditioner 2 as a maintenance target (step S7).
When a test operation is requested for each air conditioner 2, for example, a test operation of 30000 air conditioners 2 in a region in which a certain service point is responsible is started at the same time, and the test operation result is obtained in such a manner that 200 air conditioners 2 need maintenance, and the number of air conditioners 2 that can be maintained by the maintenance worker 6 in one day is assumed to be 100. In this case, since the total maintenance work of the air conditioners 2 in the area is 200, the maintenance worker 6 takes two days.
In the air conditioning system 1 of the present embodiment, based on the above-described assumption, the preset timing is set to five times per day in the intermediate period, and the preset rule is set to 6000 of the air conditioners 2 of 30000 in the same region as one group. In this case, the server 3 makes a test operation request for the smart phone terminals 4 of 6000 users of the air conditioners 2 in the same area every day, and requests test operation for the smart phone terminals 4 of all the users of the air conditioners 2 in the same area for five days. As a result, the number of maintenance recommendations generated based on the one-day test run result is reduced, that is, the number of maintenance recommendations is dispersed to five days. Further, by dispersing the time of the test operation of the air conditioner 2 in the region, the maintenance request (maintenance reservation) is dispersed based on the test operation result. By distributing the maintenance requests (maintenance reservations), the jobs of the maintenance operators 6 are distributed, and the job load of the maintenance operators 6 can be reduced.
Fig. 11 is a flowchart showing an example of the processing operation of the control unit 45 in the smartphone terminal 4 related to the trial operation request reception process. In fig. 11, the control unit 45 of the smartphone terminal 4 determines whether or not a commissioning request has been received from the server 3 (step S11). When the test run request is received (yes in step S11), the control unit 45 displays the test run request screen 43A shown in fig. 8 on the display unit 43 (step S12). As a result, the user of the smartphone terminal 4 can check the commissioning request screen 43A and confirm that the air conditioner 2 needs to be commissioned.
The control unit 45 determines whether or not a test run start operation (button operation of the button 432A) on the test run request screen 43A is detected (step S13). When the test operation start operation is detected (yes in step S13), the control unit 45 executes the test operation of the air conditioner 2, and ends the processing operation shown in fig. 11. After the process operation related to the trial operation request reception process is completed, the user of the smartphone terminal 4 can perform the trial operation of the air conditioner 2 by the button operation on the trial operation request screen 43A.
When the operation start operation is not detected (no in step S13), the control unit 45 determines whether or not the operation to reject the test operation (button operation of the button 433A) is detected (step S14). When the control unit 45 detects the rejection of the test operation (yes in step S14), it does not execute the test operation, and ends the processing operation shown in fig. 11.
When the test operation request is not received (no in step S11), the control unit 45 ends the processing operation shown in fig. 11. If the operation to reject the test operation is not detected (no in step S14), the control unit 45 proceeds to step S13 to determine whether or not the operation to start the test operation is detected.
Fig. 12 is a flowchart showing an example of the processing operation of the control unit 45 in the smartphone terminal 4 related to the maintenance reservation processing. The control unit 45 in the smartphone terminal 4 shown in fig. 12 determines whether or not the maintenance recommendation has been received from the server 3 (step S21). When the maintenance recommendation is received (yes in step S21), the control unit 45 displays the maintenance recommendation screen 43B shown in fig. 9 on the display unit 43 (step S22). As a result, the user of the smartphone terminal 4 can check the maintenance recommendation screen 43B and confirm the test operation result of the air conditioner 2.
The control unit 45 determines whether or not a maintenance recommendation start operation (button operation of the button 434B) on the maintenance recommendation screen 43B is detected (step S23). When the maintenance recommended start operation is detected (yes in step S23), the control unit 45 displays the maintenance reservation screen 43C on the display unit 43 (step S24). As a result, the user of the smartphone terminal 4 can check the maintenance reservation screen 43C and confirm the input content of the maintenance reservation of the air conditioner 2. The control unit 45 determines whether or not the maintenance reservation start operation (the button operation of the confirm button 437C) on the maintenance reservation screen 43C is detected (step S25).
When detecting the maintenance reservation start operation on the maintenance reservation screen 43C (yes in step S25), the control unit 45 transmits a maintenance reservation request to the server 3 (step S26), and ends the processing operation shown in fig. 12. As a result, the user of the smartphone terminal 4 can input a maintenance reservation on the maintenance reservation screen 43C. The user can use the smartphone terminal 4 to input reservation information including a customer name, a postal code, an address, a mailbox, a telephone number, a maintenance desired time, a model name 439C of the air conditioner, and the like, regarding the air conditioner 2 as a maintenance target. When the maintenance recommendation is not received (no in step S21), the control unit 45 ends the processing operation shown in fig. 12.
When the maintenance recommended start operation is not detected (no in step S23), the control unit 45 determines whether or not the maintenance recommended operation (button operation of the button 435B) is detected (step S27). When the control unit 45 detects that the maintenance recommended operation is denied (yes in step S27), the maintenance recommended screen 43B is erased (step S28), and the processing operation shown in fig. 12 is ended.
When the maintenance recommendation rejection operation is not detected (no in step S27), the control unit 45 proceeds to step S23 to determine whether or not the maintenance recommendation start operation is detected.
When the maintenance reservation start operation is not detected (no in step S25), the control unit 45 determines whether or not the maintenance reservation rejection operation (the button operation of the cancel button 438C) is detected (step S29). When the control unit 45 detects that the maintenance reservation operation is denied (yes in step S29), the maintenance reservation screen 43C is removed (step S30), and the processing operation shown in fig. 12 is ended. When the maintenance reservation refusal operation is not detected (no in step S29), the control unit 45 proceeds to step S25 to determine whether or not the maintenance reservation start operation is detected.
Fig. 13 is a flowchart showing an example of the processing operation of the control unit 35 in the server 3 in relation to the test run request processing. In fig. 13, the control unit 35 in the server 3 determines whether or not the preset timing is detected (step S31). When the preset timing is detected (yes in step S31), the control unit 35 refers to the device management table 341 to specify the unspecified air conditioner IDs of the group corresponding to the preset rule (step S32).
The control unit 35 refers to the device management table 341 and specifies the terminal ID corresponding to the specified air conditioner ID (step S33). The control unit 35 transmits a test operation request to the smartphone terminal 4 corresponding to the specified terminal ID (step S34). As a result, the server 3 requests the commissioning only for the smartphone terminal 4 of the air conditioner 2 corresponding to the air conditioner ID specified by the preset rule at the preset timing. The control unit 35 sets the requested commissioning flag 342C corresponding to the terminal ID of the smartphone terminal 4 that has transmitted the commissioning request to "1" and updates the content of the commissioning management table 342 (step S35). The server 3 can check the air conditioner ID and the terminal ID for which the test operation is requested by referring to the requested test operation flag 342C of the test operation management table 342.
Further, after updating the requested trial operation flag 342C to "1", the control unit 35 determines whether or not there is an unspecified air conditioner ID (step S36). If there is an unspecified air conditioner ID (yes in step S36), the control unit 35 proceeds to step S31 to determine whether or not a preset timing is detected. That is, the server 3 can specify an unspecified air conditioner ID suitable for the preset rule at each preset time. If there is no unassigned air conditioner ID (step S36: no), the control unit 35 ends the processing operation shown in fig. 13. If the preset timing is not detected (no in step S31), the control unit 35 proceeds to step S31 to determine whether the preset timing is detected. That is, the server 3 does not request a commissioning until the preset is detected.
Fig. 14 is a flowchart showing an example of the processing operation of the control unit 35 in the server 3 relating to the test result notification processing. In fig. 14, the control unit 35 in the server 3 determines whether or not the test result is received from the air conditioner 2 (step S41). When the air conditioner 2 detects an abnormality in the air conditioner 2 using the failure estimation model 132C and the refrigerant amount estimation model 133C, the test operation result is transmitted to the server 3. When the test result is received (yes in step S41), the control unit 35 extracts the air conditioner ID and the maintenance content from the test result (step S42).
The control unit 35 refers to the test run management table 342, identifies the terminal ID corresponding to the extracted air conditioner ID (step S43), transmits a maintenance recommendation to the smartphone terminal 4 corresponding to the identified terminal ID (step S44), and ends the processing operation shown in fig. 14. As a result, the server 3 can send a maintenance recommendation to the smartphone terminal 4 of the user of the air conditioner 2 based on the test operation results from the air conditioners 2. When the test result is not received (step S41: no), the control unit 35 ends the processing operation shown in fig. 14.
Fig. 15 is a flowchart showing an example of the processing operation of the control unit 35 in the server 3 in relation to the reservation registration processing. In fig. 15, the control unit 35 in the server 3 determines whether or not a maintenance reservation request has been received from the smartphone terminal 4 (step S51). When receiving the maintenance reservation request (yes in step S51), the control unit 35 extracts reservation information from the maintenance reservation request (step S52). The reservation information is information related to the air conditioner 2, which is the maintenance target, including the customer name, the zip code, the address, the mailbox, the telephone number, the maintenance desired time, the model name 439C of the air conditioner, and the like.
The control unit 35 registers the maintenance work time, maintenance content, customer information, terminal ID, and air conditioner ID in the reservation information in the maintenance management table 343 (step S53). The server 3 can refer to the maintenance management table 343 to confirm reservation information for each maintenance ID. The control unit 35 selects the maintenance operator 6 corresponding to the maintenance content (step S54), notifies the maintenance operator 6 of the maintenance content (step S55), and ends the processing operation shown in fig. 15. When the maintenance reservation request is not received (no in step S51), the control unit 35 ends the processing operation shown in fig. 15.
As described above, the server 3 of the present embodiment classifies the plurality of managed air conditioners 2 into groups according to the preset rule, and notifies the smartphone terminal 4 of the user of the air conditioner 2 in the group of the test operation request issued to the air conditioner 2 in the group in order to request the test operation for each group at a timing shifted from the middle period. As a result, the time periods in which each air conditioner 2 is put into trial operation can be distributed, and thus the maintenance work can be suppressed from being concentrated in one of the intermediate periods, and the work load on the maintenance worker 6 can be reduced. Further, by performing maintenance work in the intermediate period, it is possible to avoid a situation in which the air conditioner 2 cannot be operated during the operation period due to the maintenance work.
When receiving the commissioning request, the smartphone terminal 4 requests the air conditioner 2 corresponding to the user of the smartphone terminal 4 to start commissioning according to a preset operation. Further, the air conditioner 2 performs the test operation in response to the request for starting the test operation, and when the test operation result requiring maintenance of the air conditioner 2 is detected, notifies the server 3 of the test operation result. When receiving the result of the test operation from the air conditioner 2, the server 3 notifies the smart phone terminal 4 of the user of the air conditioner 2 of a recommendation of maintenance of the air conditioner 2. As a result, the user of each smart phone terminal 4 can quickly receive the maintenance work by acquiring the maintenance recommendation from the test result of the test operation of the air conditioner 2 performed at the staggered timing, and can avoid a situation in which the air conditioner 2 cannot be operated due to the maintenance work at the operation timing.
Upon receiving the maintenance recommendation from the server 3, the smartphone terminal 4 notifies the server 3 of information on the reservation of the maintenance work of the air conditioner 2 in accordance with a preset reservation operation. As a result, the customer can easily reserve the maintenance job.
When the failure of the air conditioner 2 is estimated by using the failure estimation model 132C based on the start of the test operation, the air conditioner 2 notifies the server 3 of the failure as a result of the test operation. As a result, each air conditioner 2 can notify the server 3 of the result of the test run using the failure estimation model 132C.
When it is estimated that the current remaining refrigerant amount flowing in the air conditioner 2 is insufficient by using the refrigerant amount estimation model 133C from the start of the test operation of the air conditioner 2, the air conditioner 2 notifies the server 3 of the result of the test operation. As a result, each air conditioner 2 can notify the server 3 of the result of the test operation using the refrigerant amount estimation model 133C.
As an example of the trial run request processing of the present embodiment, a case is shown in fig. 13 in which an unspecified air conditioner ID corresponding to a preset rule is specified, and a more specific example of the preset rule will be described based on fig. 16 to 18.
Fig. 16 is a flowchart showing an example of the processing operation of the control unit 35 in the server 3 in relation to the first test operation request processing. In fig. 16, the control unit 35 in the server 3 determines whether or not the preset timing is detected (step S61). When the preset timing is detected (yes in step S61), the control unit 35 refers to the device management table 341 and specifies the region as a preset rule in accordance with the zip code for identifying the group (step S62). The preset rule is to group the arrangement positions of the air conditioners 2 according to the zip codes registered by the user, and associate the air conditioner IDs of the air conditioners 2 corresponding to the zip codes with the group of the zip codes. Alternatively, the group may be made in accordance with the city and county village local units provided in the air conditioner 2, instead of the zip code.
The control unit 35 refers to the equipment management table 341 and specifies an unspecified air conditioner ID in the specified area (step S63). The control unit 35 refers to the device management table 341 and specifies the terminal ID corresponding to the specified air conditioner ID (step S64). The control unit 35 transmits a test operation request to the smartphone terminal 4 corresponding to the specified terminal ID (step S65). The control unit 35 sets the requested commissioning flag 342C corresponding to the terminal ID of the smartphone terminal 4 that has transmitted the commissioning request to "1" and updates the content of the commissioning management table 342 (step S66).
Further, after setting the requested trial operation flag 342C to "1", the control unit 35 determines whether or not there is an unspecified area (step S67). If there is an unspecified area (yes in step S67), the control unit 35 proceeds to step S61 to determine whether or not the preset timing is detected. If there is no unspecified area (step S67: no), the control unit 35 ends the processing operation shown in fig. 16. If the preset timing is not detected (no in step S61), the control unit 35 proceeds to step S61 to determine whether the preset timing is detected.
The control unit 35 that executes the first test run request processing designates, at each preset timing, a region corresponding to an unspecified zip code from among the plurality of zip codes as a preset rule for identifying the arrangement position of the air conditioner 2, and designates an unspecified air conditioner ID within the designated region. Further, the control unit 35 requests the smartphone terminal 4 of the user of the specified air conditioner 2 to perform a test operation based on the terminal ID of the specified air conditioner 2. As a result, the trial operation requests to the smartphone terminal 4 of the user of the air conditioner 2 are distributed for each specified region, and the acquisition timing of the trial operation result is distributed, so that the timing of the maintenance reservation can be distributed. By dispersing the timing of maintenance reservation, the jobs of the maintenance worker 6 are dispersed, and the job load of the maintenance worker 6 is reduced. Further, since the trial operation requests are distributed in the area unit, the moving distance at the time of the maintenance work of the maintenance worker 6 is shortened, and the work load of the maintenance worker 6 can be reduced.
Fig. 17 is a flowchart showing an example of the processing operation of the control unit 35 in the server 3 in relation to the second test operation request processing. In fig. 17, the control unit 35 in the server 3 determines whether or not the preset timing is detected (step S71). When the preset timing is detected (yes in step S71), the control unit 35 refers to the device management table 341 and specifies the preset number of air conditioner IDs from the plurality of air conditioner IDs as a preset rule (step S72).
The control unit 35 refers to the device management table 341 and specifies the terminal ID corresponding to the specified air conditioner ID (step S73). The control unit 35 transmits a test operation request to the smartphone terminal 4 corresponding to the specified terminal ID (step S74). The control unit 35 sets the requested commissioning flag 342C corresponding to the terminal ID of the smartphone terminal 4 that has transmitted the commissioning request to "1" and updates the content of the commissioning management table 342 (step S75).
Further, after setting the requested trial operation flag 342C to "1", the control unit 35 determines whether or not there is an unspecified air conditioner ID (step S76). If there is an unspecified air conditioner ID (yes in step S76), the control unit 35 proceeds to step S71 to determine whether or not the preset timing is detected. If there is no unassigned air conditioner ID (no in step S76), the control unit 35 ends the processing operation shown in fig. 17. If the preset timing is not detected (no in step S71), the control unit 35 proceeds to step S71 to determine whether the preset timing is detected.
The control unit 35 that executes the second test operation request processing specifies, as a preset rule, a preset number of unspecified air conditioner IDs from the plurality of air conditioner IDs at each preset timing, and requests a test operation from the smartphone terminal 4 of the specified user of the air conditioner 2 based on the terminal ID of the specified air conditioner 2. As a result, the trial operation requests to the smartphone terminal 4 of the user of the air conditioner 2 are distributed for each preset number, and the acquisition timing of the trial operation result is distributed, so that the maintenance reserved timing can be distributed. By dispersing the timing of maintenance reservation, the jobs of the maintenance worker 6 are dispersed, and the job load of the maintenance worker 6 is reduced. For example, the number of trial runs of the air conditioner 2 is halved to suppress the number of maintenance operations, thereby reducing the work load of the maintenance worker 6.
Further, as the preset rule, a case is exemplified in which a preset number of unspecified air conditioner IDs are specified from a plurality of air conditioner IDs at each preset timing, but as a different preset rule, a region such as city and county town for identifying the arrangement position of the air conditioner 2 may be specified at each preset timing, and the preset number of unspecified air conditioner IDs may be specified within the specified region.
Fig. 18 is a flowchart showing an example of the processing operation of the control unit 35 in the server 3 in relation to the third test operation request processing. In fig. 18, the control unit 35 in the server 3 determines whether or not the preset timing is detected (step S81). When the control unit 35 detects the preset timing (yes in step S81), it refers to the device management table 341 and designates an unspecified model as a preset rule (step S82).
The control unit 25 designates the number of models corresponding to the unspecified model (step S83). The control unit 35 refers to the device management table 341 and specifies, among the air conditioner IDs of the specified model, the number of unspecified air conditioners IDs specified (step S84).
The control unit 35 refers to the device management table 341 and specifies the terminal ID corresponding to the specified air conditioner ID (step S85). The control unit 35 transmits a test operation request to the smartphone terminal 4 corresponding to the specified terminal ID (step S86). The control unit 35 sets the requested commissioning flag 342C corresponding to the terminal ID of the smartphone terminal 4 that has transmitted the commissioning request to "1" and updates the content of the commissioning management table 342 (step S87).
Further, after setting the requested test run flag 342C to "1", the control unit 35 determines whether or not there is an unspecified air conditioner ID among the unspecified air conditioner IDs of the specified model (step S88). If there is an unspecified air conditioner ID (yes in step S88), the control unit 35 determines whether or not a preset timing is detected (step S89).
When the control unit 35 detects the preset timing (yes in step S89), it proceeds to step S83 to specify the number of specified units corresponding to the specified model. Further, in the case where the preset timing is not detected (no in step S89), the control section 35 proceeds to step S89 in order to determine whether the preset timing is detected.
If there is no unspecified air conditioner ID among the unspecified air conditioner IDs of the specified model (step S88: no), the control unit 35 determines whether or not there is an unspecified model (step S90). If there is an unspecified model (yes in step S90), the control unit 35 proceeds to step S82 to specify the unspecified model. If there is no model not specified (no in step S90), the control unit 35 ends the processing operation shown in fig. 18.
When the control unit 35 does not detect the preset timing (no in step S81), the processing operation shown in fig. 18 is ended.
The control section 35 that executes the third test run request processing designates, as a preset rule, an unspecified model from among the plurality of models at each preset timing, and designates a preset number of unspecified air conditioner IDs from among the unspecified air conditioner IDs of the designated model. Further, based on the terminal ID of the specified air conditioner 2, a commissioning is requested to the smartphone terminal 4 of the user of the specified air conditioner 2. As a result, the trial operation requests to the smartphone terminal 4 of the user of the air conditioner 2 are distributed for each predetermined model number, and the acquisition timing of the trial operation result is distributed, so that the maintenance reserved timing can be distributed. By dispersing the timing of maintenance reservation, the jobs of the maintenance worker 6 are dispersed, and the job load of the maintenance worker 6 is reduced. For example, by reducing the number of test runs per day for a model with a high failure rate, the work load on the maintenance worker 6 can be reduced.
For convenience of explanation, the server 3 requests the smartphone terminal 4 of the user of the air conditioner 2 to perform a test operation, and generates a refrigerant amount estimation model and a failure estimation model for each air conditioner 2 based on the operation state data collected by the air conditioner 2. However, the function of generating the refrigerant quantity estimation model and the failure estimation model may be executed by another server, and may be changed as appropriate.
The server 3 has been exemplified as notifying the smartphone terminal 4 of a recommendation of maintenance of the air conditioner 2 when a failure of the air conditioner 2 is estimated. However, the present invention is not limited to the case of estimating the failure of the air conditioner 2. The server 3 may notify the recommendation of the maintenance of the air conditioner 2 when, for example, the failure rate of the air conditioner 2 is equal to or greater than a predetermined threshold, the maintenance frequency of the air conditioner 2 is equal to or greater than a predetermined number of times, and the operation accumulation time of the air conditioner 2 is equal to or greater than a predetermined time. The server 3 may notify the recommendation of maintenance of the air conditioner 2 when the commodity selling period of the air conditioner 2 has exceeded the preset period or the commodity warranty period of the air conditioner 2 has exceeded the preset period.
Further, the case where the air conditioner 2 uses the failure estimation model 132C and the refrigerant amount estimation model 133C to estimate the failure of the air conditioner 2 is exemplified. However, the control unit 13D of the air conditioner 2 may detect various sensors in the air conditioner 2 based on the start of the test operation, for example, a power-on failure of the air conditioner 2, a remote controller operation failure, a cooling failure, a heating failure, a wind direction plate operation failure, or an abnormal discharge temperature failure.
The case where the air conditioner 2 performs the commissioning when detecting the commissioning start operation from the smartphone terminal 4 is exemplified. Instead of the above example, the air conditioner 2 may be configured to temporarily suspend execution of the test operation when a person is detected in the air-conditioning space by a human body detection sensor, not shown, of the indoor unit 12 when the test operation start operation is detected, and to execute the test operation only after no person is detected in the air-conditioning space. Further, if the execution of the test operation is requested from the air conditioner 2 by the server 3, the test operation may be executed even if the test operation from the smartphone terminal 4 is not detected, on the premise that the user of the air conditioner 2 agrees in advance.
Further, the case where the air conditioner 2 performs the commissioning in the case where the commissioning start operation from the smartphone terminal 4 is detected is exemplified. However, the commissioning start operation by the smartphone terminal 4 is not limited. The user can also view the display screen of the information on the test run transmitted to the smartphone terminal 4, and can perform a test run start operation using the remote control 14 or the like of the air conditioner 2, and can make appropriate changes.
In addition, each constituent element of each portion shown in the drawings is not necessarily physically constituted as shown in the drawings. That is, the specific form of the dispersion and combination of the respective portions is not limited to that shown in the drawings, and the entire or a part thereof may be functionally or physically dispersed or combined in any unit according to various loads, use conditions, and the like.
Further, the various processing functions performed by each device may be executed in all or any of the above-described processing functions on a CPU (central processing unit ) (or a microcomputer such as an MPU (micro processing unit ), an MCU (micro control unit, micro Controller Unit)). It is apparent that all or any part of the various processing functions may be executed on a program analyzed and executed by a CPU (or a microcomputer such as an MPU or an MCU) or on hardware using wired logic.
