In the embodiment, the temperature measured by the indoor temperature sensor 19 at the time of step S101 is defined as the indoor temperature Trb before the start of operation, and the temperature measured by the outdoor temperature sensor 18 is defined as the outdoor temperature To.

After the processing in step S101 is completed, the air conditioner 1 performs the processing in step S102. In step S102, the air conditioner side storage unit 38 stores the pre-operation indoor temperature Trb and the outdoor temperature To acquired in step S101.

After the processing of step S102 is completed, the air conditioner 1 performs the processing of step S103. In step S103, the command unit 41 transmits a command signal to start the operation of the air conditioning device 1 to the air conditioning unit 42, and starts the operation of the air conditioning device 1. In the embodiment, the command unit 41 includes a command signal for changing the four-way valve 14 to a flow path corresponding to the operation stored in the mode data, a command signal for setting the opening degree of the expansion valve 12 to a predetermined opening degree, and a command signal. A command signal for starting the operation of the compressor 10, a command signal for starting the operation of the indoor blower 16, and a command signal for starting the operation of the outdoor blower 16 are transmitted to the air conditioning unit 42. The air-conditioning unit 42 that has received various command signals starts operation, and the air-conditioning device 1 starts the air-conditioning in the room.

After the processing of step S103 is completed, the air conditioner 1 performs the processing of step S104. In step S104, the air conditioner 1 performs a standby process. The standby process is a process of waiting until the temperature of the air in the room reaches the arrival determination temperature Tac, which will be described later, after the air conditioning device 1 starts air conditioning in the room.

FIG. 6 is a flowchart of the standby process of the air conditioner according to the embodiment. Here, the standby process will be described in detail with reference to FIG.

When the standby process is started, the air conditioner 1 performs the process of step S201. In step S201, the timer unit 36 starts measuring the arrival time touch. When the timer unit 36 starts measuring the arrival time touch, the timer unit 36 resets the arrival time touch and measures the time from 0.

After the processing of step S201 is completed, the air conditioner 1 performs the processing of step S202. In step S202, the temperature acquisition unit 37 acquires the standby room temperature Trs. The standby room temperature Trs is the temperature of the air in the room during the standby process. In the embodiment, the temperature measured by the indoor temperature sensor 19 at the time of step S202 is defined as the standby indoor temperature Trs.

After the processing of step S202 is completed, the air conditioner 1 performs the processing of step S203. In step S203, the first determination unit 40 determines whether or not the air conditioner 1 is operating in the cooling operation mode. In the embodiment, the first determination unit 40 acquires the mode data stored in the air conditioner side storage unit 38, and when the mode data is data indicating that the operation is performed in the cooling operation mode, air is used. If it is determined that the air conditioner 1 is operating in the cooling operation mode and the mode data is data indicating that the operation is performed in the heating operation mode, it is assumed that the air conditioner 1 is operating in the heating operation mode. to decide.

In the process of step S203, when the first determination unit 40 determines that the air conditioner 1 is operating in the cooling operation mode (steps S203, YES), the air conditioner 1 performs the process of step S204. conduct. In step S204, the first determination unit 40 determines whether or not the standby room temperature Trs acquired in step S202 is equal to or lower than the arrival determination temperature Tac in the cooling operation mode. That is, in step S204, the first determination unit 40 determines whether or not the condition of Trs ≦ Tac is satisfied. The arrival determination temperature Tac in the cooling operation mode is a value obtained by adding the permissible difference temperature ΔTs, which is predetermined to a value of 0 or more, to the set temperature Ts. Since the set temperature Ts and the permissible difference temperature ΔTs are predetermined values, the arrival determination temperature Tac in the cooling operation mode is also a predetermined value.

In the process of step S204, when the first determination unit 40 determines that the standby room temperature Trs is equal to or lower than the arrival determination temperature Tac (step S204, YES), the air conditioner 1 performs the process of step S205. .. In step S205, the timer unit 36 ends the measurement of the arrival time touch. That is, the arrival time touch measures the time from the start of the process of step S201 to the start of the process of step S205. In other words, when the air conditioner 1 is operating in the cooling operation mode, the arrival time tack is such that the temperature of the air in the room is equal to or less than the arrival determination temperature Tac after the air conditioner 1 starts the operation in the cooling operation mode. I am measuring the time until it becomes.

After the processing of step S205 is completed, the air conditioner 1 performs the processing of step S206. In step S206, the air conditioner side storage unit 38 stores the arrival time touch for which the measurement was completed in step S205.

After the processing in step S206 is completed, the air conditioner 1 ends the standby processing.

In the process of step S204, when the first determination unit 40 determines that the standby room temperature Trs is larger than the arrival determination temperature Tac (step S204, NO), the air conditioner 1 returns to the process of step S202 and returns to the process of step S202. The temperature acquisition unit 37 acquires the standby room temperature Trs.

In the process of step S203, when the first determination unit 40 determines that the air conditioner 1 is not operating in the cooling operation mode (steps S203, NO), the air conditioner 1 performs the process of step S207. conduct. In step S207, the first determination unit 40 determines whether or not the standby room temperature Trs acquired in step S202 is equal to or higher than the arrival determination temperature Tah in the heating operation mode. That is, in step S207, the first determination unit 40 determines whether or not the condition of Trs ≧ Tah is satisfied. The arrival determination temperature Tah in the heating operation mode is a value obtained by subtracting the permissible difference temperature ΔTs, which is set to a value of 0 or more in advance, with respect to the set temperature Ts. Since the set temperature Ts and the permissible difference temperature ΔTs are predetermined values, the arrival determination temperature Tah in the heating operation mode is also a predetermined value.

In the process of step S207, when the first determination unit 40 determines that the standby indoor temperature Trs is equal to or higher than the arrival determination temperature Tah (steps S207, YES), the air conditioner 1 performs the process of step S205. , The measurement of the arrival time touch is completed. That is, when the air conditioner 1 is operating in the heating operation mode, the arrival time touch is such that the temperature of the air in the room becomes equal to or higher than the arrival determination temperature Tah after the air conditioner 1 starts operation in the heating operation mode. I am measuring the time until it becomes. After the process of step S205 is completed, the air conditioner 1 performs the process of step S206, and the air conditioner side storage unit 38 stores the arrival time touch. After the processing in step S206 is completed, the air conditioner 1 ends the standby processing.

In the process of step S207, when the first determination unit 40 determines that the standby room temperature Trs is smaller than the arrival determination temperature Tah (steps S207, NO), the air conditioner 1 returns to the process of step S202. The temperature acquisition unit 37 acquires the standby room temperature Trs.

The operation data storage control after the standby process in step S104 is completed will be described with reference to FIG. After the processing of step S104 is completed, the air conditioner 1 performs the processing of step S105. In step S105, the data generation unit 43 generates an operation data group and an arrival time data group. The operation data group is a data group indicating under what circumstances the air conditioner 1 is operating, and is composed of a plurality of data. The operation data group includes at least the room temperature Trb before the start of operation and model data. Further, in the embodiment, the operation data group includes the outdoor temperature To, the set temperature Ts, and the installation date in addition to the indoor temperature Trb before the start of operation and the model data. The arrival time data group is a data group relating to the time from the start of operation of the air conditioner 1 to the arrival determination temperature, and is composed of a single data or a plurality of data. The arrival time data group includes at least the arrival time touch. In the embodiment, the arrival time data group includes only the arrival time touch. In the following description, when both the operation data group and the arrival data group are referred to, they are simply referred to as a data group.

After the processing of step S105 is completed, the air conditioner 1 performs the processing of step S106. In step S106, the air conditioner side transmission unit 44 converts the data group generated in step S105 into a signal, and transmits the converted signal to the server 5. Here, the signal transmitted from the air conditioner 1 in step S106 is referred to as a storage feed signal.

After the processing of step S106 is completed, the server 5 performs the processing of step S107. In step S107, the server-side receiving unit 54 receives the stored feed signal transmitted from the air conditioner 1 in step S106. Further, in step S107, the server-side receiving unit 54 converts the stored feed signal into a format in which the server-side storage unit 55 can store the data group.

After the processing of step S107 is completed, the server 5 performs the processing of step S108. In step S108, the server-side storage unit 55 associates and stores the data included in the data group. That is, in step S108, the server-side storage unit 55 stores at least the room temperature Trb before the start of operation, the model data, and the arrival time touch in association with each other. Further, in the embodiment, the server-side storage unit 55 stores the indoor temperature Trb before the start of operation, the set temperature Ts, the arrival time touch, the outdoor temperature To, the model data, and the installation date in association with each other. Further, in the following description, the operation data group and the arrival time data group stored in the server-side storage unit 55 will be referred to as a storage operation data group and a storage arrival time data group, respectively. Further, when it refers to both the storage operation data group and the storage arrival time data group, it is referred to as a storage data group. Further, the indoor temperature Trb before the start of operation, the set temperature Ts, the outdoor temperature To, the model data, the installation date, and the arrival time stored in the storage unit 55 on the server side are stored. And the memory model data, the memory installation date, and the memory arrival time, respectively.

FIG. 7 is a diagram for explaining data stored in the server-side storage unit according to the air conditioning system of the embodiment. As shown in FIG. 7, in the server-side storage unit 55, the same ID (Identification) includes the pre-operation indoor temperature Trb, the set temperature Ts, the arrival time touch, the outdoor temperature To, the model data, and the installation date included in the same storage feed signal. It is associated and memorized by adding. For example, the storage model data of MSZ-AXXX with ID 0001, the storage installation date of February 14, 2010, the storage temperature of 28.0 ° C before air conditioning, and the storage of 30.0 ° C. The outdoor temperature, the storage set temperature of 24.0 ° C., and the storage arrival time of 730 sec are the data originally included in the same storage feed signal.

The operation data storage control after the processing of step S108 is completed will be described with reference to FIG. After the processing of step S108 is completed, the server 5 performs the processing of step S109. In step S109, the server-side transmission unit 58 transmits the storage return signal to the air conditioner 1 that has transmitted the storage feed signal. The storage return signal includes data for notifying that the data included in the operation data group and the arrival time data group is stored in the server-side storage unit 55.

After the processing in step S109 is completed, the server 5 ends the operation data storage control. Further, after the processing in step S109 is completed, the air conditioner 1 performs the processing in step S110. In step S110, the air conditioner side receiving unit 45 receives the accumulated return signal transmitted from the server 5 in step S109. After the processing of step S110 is completed, the air conditioner 1 ends the operation data storage control.

The air conditioning system 100 controls the accumulation of operation data. As a result, the server 5 accumulates the data included in the operation data group and the arrival time data group generated by the air conditioner 1 connected to the server 5 so as to be able to transmit or receive the data. For example, in FIG. 1, the server 5 stores the data included in the operation data group and the arrival time data group generated by the four air conditioner 1s 1a to 1d.

Further, when the set temperature Ts is changed while the air conditioning system 100 is processing the operation data accumulation control from step S101 to step S105, the air conditioning system 100 performs the operation before the set temperature Ts is changed. The operation data storage control is terminated and the operation data storage control is newly started.

FIG. 8 is a sequence diagram of operation data analysis control of the air conditioning system according to the embodiment. Next, the operation data analysis control of the air conditioning system 100 will be described with reference to FIG. In the operation data analysis control, analysis is performed based on the operation data group of the air conditioner 1 at the time of the operation data analysis control and the storage data group stored in the server 5, and whether or not the capacity of the air conditioner 1 is deteriorated. It is a control to judge whether or not. Further, the operation data analysis control starts the operation of the air conditioner 1 when the user inputs an operation to operate the air conditioner 1 to the input unit 39 or when the time reaches a preset operation start time. It is executed when you do. That is, in the embodiment, the operation data analysis control is started at the same timing as the operation data accumulation control. Further, when the operation data analysis control is executed, the storage unit 38 on the air conditioner side determines the set temperature Ts and whether the air conditioner 1 operates in the cooling operation mode or the heating operation mode. The mode data and the analysis correction value Td are stored. The analysis correction value Td is a value used in determining whether or not the capacity of the air conditioner 1 is deteriorated in the operation data analysis control, and is predetermined to be an arbitrary value of 0 or more.

When the air conditioning system 100 starts the operation data analysis control, the air conditioning device 1 first performs the process of step S301. In step S301, as in step S101, the temperature acquisition unit 37 sets the pre-operation indoor temperature Trb, which is the temperature of the indoor air before the air conditioner 1 starts operation, and the outdoor temperature To, which is the temperature of the outdoor air. get. Since the process of step S301 is the same as the process of step S101 described above and the operation data analysis control and the operation data storage control are started at the same timing, the process of step S101 and step S301 is the same one process. It may be.

After the processing of step S301 is completed, the air conditioner 1 performs the processing of step S302. In step S302, the air conditioner side storage unit 38 stores the pre-operation indoor temperature Trb and the outdoor temperature To acquired in step S301 in the same manner as in step S102. For the same reason as in step S301, step S102 and step S302 may be treated as the same process.

After the processing of step S302 is completed, the air conditioner 1 performs the processing of step S303. In step S303, the data generation unit 43 generates an operation data group. The operation data group generated in step S303 is the same as the operation data group described in the process of step S105. When the processing of step S105 is performed before the processing of step S303, the operation data group generated in step S105 is used as the operation data group in the operation data analysis control without generating the operation data group in step S303. You may use it. Further, when the processing of step S303 is performed before the processing of step S105, the operation data group generated in step S303 is used as the operation data group in the operation data storage control without generating the operation data group in step S105. You may use it.

After the processing of step S303 is completed, the air conditioner 1 performs the processing of step S304. In step S304, the air conditioner side transmission unit 44 converts the operation data group generated in step S303 into a signal, and transmits the converted signal to the server 5. Here, the signal transmitted from the air conditioner 1 in step S304 is referred to as an analysis feed signal.

After the process of step S304 is completed, the air conditioner 1 performs the process of step S305. In step S305, similarly to step S103, the command unit 41 transmits a command signal to start the operation of the air conditioning device 1 to the air conditioning unit 42, and starts the operation of the air conditioning device 1. If the process of step S103 has already been performed and the air conditioner 1 is operating at the time when the process of step S305 is started, the process of step S305 is omitted and the process of step S305 is treated as completed.

After the process of step S304 is completed, the server 5 performs the process of step S306. In step S306, the server-side receiving unit 54 receives the analysis feed signal transmitted from the air conditioner 1 in step S304. Further, in step S306, the server-side receiving unit 54 converts the analysis feed signal into a format in which the analysis unit 56 can acquire the data of the operation data group.

After the process of step S306 is completed, the server 5 performs the process of step S307. In step S307, the analysis unit 56 extracts from the server-side storage unit 55 the storage arrival time associated with the storage operation data group related to the data of the operation data group included in the analysis feed signal. In the embodiment, the pre-operation indoor temperature Trb, the set temperature Ts, the outdoor temperature To, the model data, and the storage date, which are included in the analysis feed signal, are related to the pre-operation indoor temperature, the storage set temperature, and the storage outdoor temperature, respectively. And the storage arrival time associated with the storage model data and the storage installation date is extracted. More specifically, the associated storage pre-start indoor temperature, storage set temperature Ts, storage outdoor temperature To, and storage model data are analyzed in step S306. The pre-operation indoor temperature Trb and the set temperature are included in the feed signal. The Ts, the outdoor temperature To, and the model data match, and the storage arrival time after the installation date in which the associated storage installation date is included in the analysis feed signal is extracted.

The process of step S307 will be described in detail with reference to FIG. 7. For example, the data of the operation data group included in the analysis feed signal received in step S306 is that the model data is MSZ-AXXXX, the installation date is January 30, 2010, and the room temperature Trb before air conditioning is 28. It is assumed that the temperature is 0 ° C., the outdoor temperature To is 30.0 ° C., and the set temperature Ts is 24.0 ° C. In this case, the storage arrival time extracted by the process of step S307 is 730 sec with

ID

0001, 710 sec with

ID

0007, and 720 sec with ID 0008. As for ID0002, the storage model data is different from the model data included in the analysis feed signal. Therefore, for ID0003, the storage outdoor temperature is different from the outdoor temperature To included in the analysis feed signal. Is different from the air conditioning pre-chamber temperature Trb included in the analysis feed signal, so the storage set temperature is different from the set temperature Ts included in the analysis feed signal for ID0005, so the storage installation date is included in the analysis feed signal for ID0006. Since it is before the installation date, the arrival time data with each ID is not extracted.

The operation data analysis control after the processing of step S307 is completed will be described with reference to FIG. After the processing of step S307 is completed, the server performs the processing of step S308. In step S308, the calculation unit 57 calculates the threshold time tt based on the memory arrival time extracted in step S307. As a method of calculating the threshold time tt based on the memory arrival time, for example, a method in which the average value of the memory arrival time extracted in step S307 is set as the threshold time tt, and a method in which the storage arrival time extracted in step S307 has a large indoor space. The method of setting the weighted average value in consideration of the size of the indoor space with the increased weight to be applied as the threshold time tt, the method of setting the median value of the storage arrival time extracted in step S307 as the threshold time tt, or the method of extracting in step S307. Examples thereof include a method in which the most frequent value of the stored memory arrival time is set as the threshold time tt. In the embodiment, the average value of the memory arrival time extracted in step S307 is defined as the threshold time tt.

A specific example of the processing in step S308 will be described. For example, it is assumed that the memory arrival times extracted in step S307 are 730 sec, 710 sec, and 720 sec. In this case, in the embodiment, the average value of the storage arrival times extracted in step S307 is set as the threshold time tt, so that the threshold time tt is 720 sec.

After the process of step S308 is completed, the server 5 performs the process of step S309. In step S309, the server-side transmission unit 58 transmits the analysis return signal to the air conditioner 1 that has transmitted the analysis transmission signal. The analysis return signal includes the threshold time tt derived in step S308. That is, in step S309, the server 5 provides the air conditioner 1 with the threshold time tt.

After the processing in step S309 is completed, the server 5 ends the operation data analysis control. Further, after the processing of step S305 and step S309 is completed, the air conditioner 1 performs the processing of step S310. In step S310, the air conditioner side receiving unit 45 receives the analysis return signal transmitted from the server 5 in step S309. Further, in step S310, the receiving unit 45 on the air conditioner side converts the analysis return signal into a format in which the second determination unit 46 can acquire the threshold time tt.

After the processing of step S310 is completed, the air conditioner 1 performs the processing of step 311. In step S311, the air conditioner 1 performs a capacity reduction determination process. The capacity reduction determination process is a process for determining whether or not the capacity of the air conditioner 1 is reduced.

FIG. 9 is a flowchart of the capacity reduction determination process of the air conditioner according to the embodiment. Here, the capacity reduction determination process will be described in detail with reference to FIG.

When the capacity reduction determination process is started, the air conditioner 1 performs the process of step S401. In step S401, the timer unit 36 starts measuring the elapsed time t. When the timer unit 36 starts measuring the elapsed time t, the timer unit 36 resets the elapsed time t and measures the time from 0.

After the processing of step S401 is completed, the air conditioner 1 performs the processing of step S402. In step S402, the second determination unit 46 determines whether or not the elapsed time t has elapsed the threshold time tt included in the analysis return signal received in step S310. That is, in step S402, the second determination unit 46 determines whether or not the condition of t ≧ tt is satisfied.

In the process of step S402, when the second determination unit 46 determines that the elapsed time t has not elapsed the threshold time tt (steps S402, NO), the air conditioner 1 performs the process of step S402 again. ..

In the process of step S402, when the second determination unit 46 determines that the elapsed time t has passed the threshold time tt (step S402, YES), the air conditioner 1 performs the process of step S403. In step S403, the temperature acquisition unit 37 acquires the indoor temperature Tra after the threshold time, which is the temperature of the air in the room after the threshold time tt has elapsed. In the embodiment, the temperature measured by the indoor temperature sensor 19 at the time of step S403 is defined as the indoor temperature Tra after the threshold time.

After the processing of step S403 is completed, the air conditioner 1 performs the processing of step S404. In step S404, the second determination unit 46 determines whether or not the air conditioner 1 is operating in the cooling operation mode. In the embodiment, the second determination unit 46 acquires the mode data stored in the air conditioner side storage unit 38 as in step S203, and the mode data indicates that the operation is performed in the cooling operation mode. If, it is determined that the air conditioner 1 is operating in the cooling operation mode, and if the mode data is data indicating that the operation is performed in the heating operation mode, the air conditioner 1 is operated in the heating operation mode. Judge that you are doing.

In the process of step S404, when the second determination unit 46 determines that the air conditioner 1 is operating in the cooling operation mode (steps S404, YES), the air conditioner 1 performs the process of step S405. conduct. In step S405, the second determination unit 46 determines whether or not the capacity of the air conditioner 1 is reduced based on the room temperature Tra after the threshold time, the set temperature Ts, and the analysis correction value Td acquired in step S403. In the embodiment, in step S405, the second determination unit 46 determines whether or not the room temperature Tra after the threshold time is larger than the sum of the set temperature Ts and the analysis correction value Td. That is, in step S405, the second determination unit 46 determines whether or not the condition of Tra> Ts + Td is satisfied. Further, the second determination unit 46 of the embodiment determines that the capacity of the air conditioner 1 is reduced when the condition of Tra> Ts + Td is satisfied, and when the condition of Tra> Ts + Td is not satisfied, the air conditioner is harmonized. It is determined that the capacity of the device 1 has not deteriorated.

FIG. 10 shows the temperature of the air in the room and the start of operation of the air conditioner when the second determination unit of the air conditioner according to the embodiment determines that the capacity of the air conditioner has not deteriorated in the cooling operation mode. This is an example of a graph showing the relationship with the elapsed time from. FIG. 11 shows the temperature of the air in the room and the start of operation of the air conditioner when the second determination unit of the air conditioner according to the embodiment determines that the capacity of the air conditioner is reduced in the cooling operation mode. This is an example of a graph showing the relationship with the elapsed time from. The reason why it is possible to determine whether or not the capacity of the air conditioner 1 is reduced based on the room temperature Tra after the threshold time, the set temperature Ts, and the analysis correction value Td will be described with reference to FIGS. 10 and 11. In FIGS. 10 and 11, it is assumed that the process of starting the operation of the air conditioner 1 in step S305 and the process of starting the measurement of the elapsed time t in step S401 are started at substantially the same timing.

Since the air conditioner 1 is operated in the cooling operation mode, the temperature of the air in the room decreases as the elapsed time from the start of operation of the air conditioner increases in both FIGS. 10 and 11. However, the amount of decrease in the temperature of the indoor air per elapsed time is smaller in FIG. 11 than in FIG. Therefore, assuming that the room temperature after the threshold time is Tra, which is the temperature of the air in the room when the elapsed time reaches the threshold time tt, the room temperature after the threshold time in FIG. 11 is compared with the room temperature Tra after the threshold time in FIG. Tra is higher.

The room temperature Tra after the threshold time in FIG. 10 is smaller than the sum of the set temperature Ts and the analysis correction value Td. Therefore, in FIG. 10, the condition of Tra> Ts + Td is not satisfied.

The room temperature Tra after the threshold time in FIG. 11 is larger than the sum of the set temperature Ts and the analysis correction value Td. Therefore, in FIG. 11, the condition of Tra> Ts + Td is satisfied.

Further, in the embodiment, the threshold time tt matches the indoor temperature Trb before the start of operation, the set temperature Ts, the outdoor temperature To, and the model data of the air conditioner 1 that controls the operation data analysis, and the installation date is the operation. The average value of the storage arrival time of the air conditioner 1 after the air conditioner 1 that controls the data analysis is used. Therefore, the fact that the condition of Tra> Ts + Td is not satisfied can be said to be higher or equivalent to the average cooling capacity of the air conditioner 1 of the same model installed under the same environment. Further, satisfying the condition of Tra> Ts + Td means that the cooling capacity is lower than the average cooling capacity of the air conditioner 1 of the same model installed under the same environment. Further, the cooling capacity corresponds to the capacity of the air conditioner 1 in the cooling operation mode. Therefore, it can be determined whether or not the capacity of the air conditioner 1 is reduced based on the room temperature Tra after the threshold time, the set temperature Ts, and the analysis correction value Td.

The capacity reduction determination process after the process of step S405 is completed will be described with reference to FIG. When the second determination unit 46 determines that the capacity of the air conditioner 1 is reduced in the process of step S405 (steps S405 and YES), the air conditioner 1 performs the process of step S406. In step S406, the notification control unit 47 controls the notification unit 48 so that the notification unit 48 notifies the user that the capacity of the air conditioner 1 is reduced. In the embodiment, in step S406, the notification control unit 47 generates display data to be displayed on the display, which is the notification unit 48, and the display displays the generated display data.

FIG. 12 is a diagram showing an example of display contents displayed on the notification unit of the air conditioner according to the embodiment. In the embodiment, the display content shown in FIG. 12 is displayed on the notification unit 48 in step S407. The display contents include the symbol information 48a and the character information 48b. The symbol information 48a uses a symbol to notify that the capacity of the air conditioner 1 is reduced. The symbol information 48a is, for example, a graph showing the relationship between the temperature of the air in the room and the time. The character information 48b uses characters to notify that the capacity of the air conditioner 1 is reduced. The character information 18a is, for example, a sentence of "the cooling capacity is reduced". In addition, the text information 18a of the embodiment is a sentence of "As a result of analyzing the operation data of the same model and the operation data of this air conditioner, the cooling capacity is reduced, so it is recommended to purchase a new air conditioner." Is displayed, and the text is a text prompting a new purchase of the air conditioner 1.

The capacity reduction determination process after the process of step S406 is completed will be described with reference to FIG. After the end of step S406, the air conditioner 1 ends the capacity reduction determination process.

When the second determination unit 46 determines that the capacity of the air conditioner 1 has not decreased in the process of step S405 (steps S405 and NO), the air conditioner 1 ends the capacity decrease determination process.

When the second determination unit 46 determines that the air conditioner 1 is not operating in the cooling operation mode in the process of step S404 (step S404, NO), the air conditioner 1 performs the process of step S407. conduct. In step S407, the second determination unit 46 determines whether or not the capacity of the air conditioner 1 is reduced based on the room temperature Tra after the threshold time, the set temperature Ts, and the analysis correction value Td acquired in step S403. In the embodiment, the air conditioner 1 is operated in the heating operation mode. Therefore, in the embodiment, in step S407, the second determination unit 46 determines whether or not the room temperature Tra after the threshold time is smaller than the difference between the set temperature Ts and the analysis correction value Td. That is, in step S405, the second determination unit 46 determines whether or not the condition of Tra <Ts-Td is satisfied. Further, the second determination unit 46 of the embodiment determines that the capacity of the air conditioner 1 is reduced when the condition of Tra <Ts-Td is satisfied, and does not satisfy the condition of Tra <Ts-Td. In that case, it is determined that the capacity of the air conditioner 1 has not deteriorated.

As described in step S405, in the embodiment, the threshold time tt is a combination of the indoor temperature Trb before the start of operation of the air conditioner 1 performing operation data analysis control, the set temperature Ts, the outdoor temperature To, and the model data. However, the average value of the past arrival times of the air conditioner 1 after the installation date of the air conditioner 1 whose operation data analysis control is performed is used. Therefore, the fact that the condition of Tra <Ts-Td is not satisfied can be said to be higher or equivalent to the average heating capacity of the air conditioner 1 of the same model installed under the same environment. .. Further, satisfying the condition of Tra <Ts-Td means that the heating capacity is lower than the average heating capacity of the air conditioner 1 of the same model installed under the same environment. Further, the heating capacity corresponds to the capacity of the air conditioner 1 in the heating operation mode. Therefore, it can be determined whether or not the capacity of the air conditioner 1 is reduced based on the room temperature Tra after the threshold time, the set temperature Ts, and the analysis correction value Td.

When the second determination unit 46 determines that the capacity of the air conditioner 1 is reduced (step S407, YES), the air conditioner 1 performs the processing of step S406, and then the air conditioner 1. 1 ends the capacity reduction determination process. Since the process of step S406 is the same as the process described above, the description thereof will be omitted.

When the second determination unit 46 determines that the capacity of the air conditioner 1 has not decreased in the process of step S407 (step S407, NO), the air conditioner 1 ends the capacity decrease determination process.

An example of modification of the embodiment will be described.

In the embodiment, when the indoor temperature before the start of the storage operation matches the indoor temperature Trb before the start of the operation, the indoor temperature before the start of the storage operation is related to the indoor temperature Trb before the start of the operation, but the present invention is not limited to this. When the room temperature before the start of the storage operation is within the temperature range in which the room temperature Trb is contained, the room temperature before the start of the storage operation may be related to the room temperature Trb before the start of the operation. For example, the indoor temperature before the start of the storage operation is lower than the indoor temperature Trb before the start of operation by a predetermined temperature, which is equal to or higher than the indoor temperature Trbl before the start of operation, and is higher than the indoor temperature Trb before the start of operation by a predetermined temperature. If it is within the range of the room temperature Trbh or less, it may be related to the room temperature Trb before the start of operation. More specifically, when the indoor temperature Trb before the start of operation is 30.0 ° C., 29.5 ° C., which is 0.5 ° C. lower than the indoor temperature Trb before the start of operation, is set as the lower limit indoor temperature Trbl before the start of operation. When the upper limit pre-start room temperature Trbh is 30.5 ° C, which is 0.5 ° C higher than the pre-start room temperature Trb, and the pre-start room temperature falls within the temperature range of 29.5 ° C to 30.5 ° C. The room temperature before the start of operation may be related to the room temperature Trb before the start of operation. Similarly, regarding the storage set temperature, when the storage set temperature is within the temperature range in which the set temperature Ts is entered, the storage set temperature may be related to the set temperature Ts. Similarly, regarding the storage outdoor temperature, when the storage outdoor temperature falls within the temperature range in which the outdoor temperature To enters, the storage outdoor temperature may be related to the outdoor temperature To.

However, if the room temperature before the start of the memory operation matches the room temperature Trb before the start of the operation and the room temperature before the start of the memory operation is related to the room temperature Trb before the start of the operation, the room temperature Trb before the start of the operation is entered. When the room temperature before the start of the storage operation is within the temperature range, the room temperature before the start of the storage operation can derive a more appropriate threshold time tt as compared with the case where the room temperature before the start of the operation is related to the room temperature Trb. In the latter case, for example, when the majority of the room temperature before the start of the memory operation is higher than the room temperature Trb before the start of the memory operation, the room temperature before the start of the memory operation is the room temperature before the start of the memory operation. This is because the case where the temperature in the room before the start of the memory operation is related to the temperature Trb in the room before the start of the operation when it matches the temperature in the front room Trb includes a case where a clearly appropriate threshold time tt is set. Therefore, when the indoor temperature before the start of the memory operation matches the indoor temperature Trb before the start of the operation, it is desirable that the indoor temperature before the start of the memory operation is related to the indoor temperature Trb before the start of the operation. This also applies to the storage set temperature and the storage outdoor temperature.

In the embodiment, when the storage model data matches the model data, the storage model data is related to the model data, but the present invention is not limited to this, and even if the storage model data and the model data do not exactly match. The storage model data and the model data may be related. For example, when the air conditioner whose model data is MSZ-AXXX is replaced by the air conditioner whose model data is MSZ-AZZZ due to a model change, when the model data is MSZ-AXXX, the stored model data is MSZ-AZZZ. Data may also be relevant.

However, as in the case of the room temperature before the start of storage operation, if the storage model data matches the model data and the storage model data is related to the model data, the storage model data and the model data do not exactly match. Even so, a more appropriate threshold time tt can be derived as compared with the case where the storage model data and the model data are related. Therefore, when the stored model data matches the model data, it is desirable that the stored model data is related to the model data.

In the embodiment, when the memory installation date is a date after the installation date, the memory installation date is related to the installation date, but the present invention is not limited to this, and the memory installation date is a date before the installation date. Even if there is, it may be said that the storage model data and the model data are related.

However, if the storage installation date is later than the installation date and the storage model data is related to the model data, even if the storage installation date is earlier than the installation date, it will be the storage model data. A more appropriate threshold time tt can be derived as compared with the case where the model data is involved. This means that if the storage installation date is earlier than the installation date, the storage operation data associated with the storage installation date is the storage operation data for the air conditioner older than the air conditioner for which the installation date was acquired. This is because there is a high possibility that the data is stored operation data when the capacity is lowered as compared with the case where the storage installation date is a date after the installation date. It is clear that a more appropriate threshold time tt is set when the storage operation data is smaller when the capacity is reduced. Therefore, it is preferable that the storage model data is related to the model data when the storage installation date is later than the installation date.

Further, in the embodiment, the indoor temperature before the start of operation Trb, the set temperature Ts, the outdoor temperature To, the model data, and the storage date related to the installation date are stored. And the memory arrival time associated with the memory installation date is extracted, but not limited to this. At least the storage arrival time associated with the storage pre-start indoor temperature and the storage model data related to the pre-operation start room temperature Trb and the model data may be extracted. However, a more appropriate threshold time tt is set by specifying using the set temperature Ts, the outdoor temperature To, and the installation date. Further, the storage arrival time associated with the storage data related to the data may be extracted by using the indoor temperature Trb before the start of operation, the set temperature Ts, the outdoor temperature To, the model data, and the data other than the installation date.

Further, in the embodiment, the calculation unit 57 is provided in the server 5, but the present invention is not limited to this, and the calculation unit 57 may be provided in the air conditioner 1. In this case, the arithmetic unit 57 is realized by the

The analysis return signal transmitted in step S309 includes the storage arrival time extracted in step S307. Then, after the processing of step S309 is completed, the air conditioner 1 performs the processing of step S308 to derive the threshold time tt.
