Also, in the following drawings, in order to make each configuration easier to understand, the scale and number in each structure may be different from those in the actual structure.

[0014] (Configuration of Component Diagnosis System) FIG. 1 is a block diagram showing an example of a component diagnosis system according to the first embodiment. The component diagnosis system includes, for example, a plurality of air conditioners 100, a data server device 200, an owner's terminal device 300, and a maintenance technician's terminal device 400. In the following description, when collectively referring to a plurality of air conditioners 100, they will be simply referred to as "air conditioner 100". The data server device 200, the owner's terminal device 300, and the maintenance technician's terminal device 400 have a communication interface (not shown) such as a NIC (Network Interface Card) or a wireless communication module for connecting to the network NW. In the following description, the user of the air conditioner 100 will be referred to as "user", the owner of the air conditioner 100 will be referred to as "owner", and the person who provides services such as maintenance of the air conditioner 100 as an occupation will be referred to as "maintenance technician".

[0015] The air conditioner 100 includes, for example, an outdoor unit 10, an indoor unit 20, and a communication device 30. The communication device 30 may be connected via a wired signal line or communicatively connected wirelessly, for example, as long as it can communicate with the indoor unit 20 and the outdoor unit 10. The outdoor unit 10 is disposed outdoors. The indoor unit 20 is disposed indoors. The outdoor unit 10 and the indoor unit 20 are connected to each other by a circulation path portion through which the refrigerant circulates. The air conditioner 100 adjusts the temperature of the indoor air by performing heat exchange between the refrigerant flowing in the circulation path portion and the indoor air where the indoor unit 20 is disposed.

[0016] The air conditioner 100 communicates with, for example, the operation unit 110 and the information processing terminal 120.

Examples of the refrigerant 19 include a fluorine-based refrigerant having a low global warming potential (GWP: Global Warming Potential), or a hydrocarbon-based refrigerant.

[0022] The outdoor unit 10 includes, for example, a housing 11, a compressor 12, a heat exchanger 13, a flow control valve 14, a blower 15, a four-way valve 16, and a control unit 17. Inside the housing 11, the compressor 12, the heat exchanger 13, the flow control valve 14, the blower 15, the four-way valve 16, and the control unit 17 are accommodated.

[0023] The compressor 12, the heat exchanger 13, the flow control valve 14, and the four-way valve 16 are provided in a portion of the circulation path section 18 that is located inside the housing 11.

[0024] The four-way valve 16 is provided in a portion of the circulation path section 18 that is connected to the refrigerant discharge side of the compressor 12. The four-way valve 16 switches the path of the refrigerant 19 flowing in the circulation path section 18 between the path indicated by the solid line and the path indicated by the broken line. The path indicated by the solid line is a path that returns the refrigerant 19 discharged from the compressor 12 to the compressor 12 via the heat exchanger 13, the flow control valve 14, and the indoor unit 20. The path indicated by the broken line is a path that returns the refrigerant 19 discharged from the compressor 12 to the compressor 12 via the indoor unit 20, the flow control valve 14, and the heat exchanger 13.

[0025] The indoor unit 20 includes a housing 21, a heat exchanger 22, a blower 23, and a control unit 24. The housing 21 houses the heat exchanger 22, the blower 23, the control unit 24, and a communication device 30 inside. The indoor unit 20 is capable of performing a cooling operation for cooling the air in the room where the indoor unit 20 is disposed and a heating operation for heating the air in the room where the indoor unit 20 is disposed.

[0026] When performing a cooling operation with the air conditioner 100, the refrigerant 19 circulates so as to return to the compressor 12 through the compressor 12, the heat exchanger 13 of the outdoor unit 10, the flow control valve 14, and the heat exchanger 22 of the indoor unit 20 in this order, as indicated by the solid arrow. In the cooling operation, the heat exchanger 13 in the outdoor unit 10 functions as a condenser, and the heat exchanger 22 in the indoor unit 20 functions as an evaporator.

[0027] When the air conditioner 100 performs a heating operation, the refrigerant 19 circulates through the compressor 12, the heat exchanger 22 of the indoor unit 20, the flow rate adjustment valve 14, and the heat exchanger 13 of the outdoor unit 10 in this order and returns to the compressor 12 as indicated by the dashed arrow. In the heating operation, the heat exchanger 13 in the outdoor unit 10 functions as an evaporator, and the heat exchanger 22 in the indoor unit 20 functions as a condenser.

[0028] The control unit 24 is mounted on the control board in the indoor unit 20 together with the storage unit 24a. The communication device 30 is connected, for example, wired or wirelessly to the signal output terminal of the control board. The control unit 24 controls each part of the indoor unit 20. The control unit 17 is mounted on the control board in the outdoor unit 10 together with the storage unit 17a. The control unit 17 controls each part of the outdoor unit 10. The control unit 24 and the control unit 17 are realized, for example, by a processor such as a CPU (Central Processing Unit) executing a program stored in a program memory. Software, firmware, or a combination of software and firmware is described as a program, and the program is stored in the program memory. Also, some or all of the functional units may be realized by hardware such as LSI (Large Scale Integration), ASIC (Application Specific Integrated Circuit), or FPGA (Field-Programmable Gate Array), or may be realized by the cooperation of software and hardware. The storage units 17a and 24a are realized by, for example, non-volatile or volatile semiconductor memories such as RAM (Random Access Memory), ROM (Read Only Memory), flash memory, EPROM (Erasable Programmable Read Only Memory), EEPROM (Electrically Erasable and Programmable ROM).

[0029] Specifically, the control unit 24 communicates with the operation unit 110 and the information processing terminal 120. The control unit 24 receives signals from sensors (not shown) mounted on the outdoor unit 10 and the indoor unit 20. The control unit 24 controls the motor in the blower 23. The control unit 24 supplies a control signal for operating the outdoor unit 10 to the control unit 17. The control unit 17 controls the motor in the compressor 12, the motor in the blower 15, the actuator in the four-way valve 16, and the actuator in the flow rate adjustment valve 14.

[0030] The sensors may include, for example, temperature sensors that detect various temperatures such as the outside air temperature, the room temperature, the refrigerant pipe temperature, and the shell temperature of the compressor 12, sensors that detect various driving amounts such as the driving amount of the blower 15, the driving amount of the blower 23, and the driving amount of the compressor 12, sensors that detect various operations such as the operation of the flow rate adjustment valve 14 and the operation of the four-way valve 16, refrigerant leakage sensors arranged around the outdoor unit 10 and the indoor unit 20, and the like.

[0031] FIG. 4 is a block diagram showing an example of the functional configuration of the air conditioner 100 and the data server device 200 in the first embodiment. The air conditioner 100 includes, for example, a control unit 130 corresponding to the control units 17 and 24, a data acquisition unit 132, a processing unit 134, a storage unit 136 corresponding to the storage units 17a and 24a, an external communication unit 138, and an in-house communication unit 140. The external communication unit 138 corresponds to the communication device 30. Note that the communication device 30 may be connected to the control board of the outdoor unit 10 or the control board of the indoor unit 20, as long as it can acquire the operation data and component operation data stored in the control board. The processing of the control unit 130 described below may be performed by either one of the control units 17 or 24 or distributed. The storage unit 136 described below may be either one of the storage units 17a or 24a or distributed. The data acquisition unit 132 and the processing unit 134 are realized, for example, by a processor such as a CPU executing a program stored in a program memory.

[0032] The control unit 130 outputs control signals to each part of the air conditioner 100. The data acquisition unit 132 acquires the operation data and component operation data of the air conditioner 100. The storage unit 136 stores the operation data and component operation data of the air conditioner 100. The component operation data stored in the storage unit 136 is updated to the value integrated by the processing unit 134 acquired by the data acquisition unit 132. The processing unit 134 transmits the operation data and component operation data stored in the storage unit 136 to the data server device 200 via the external communication unit 138. The external communication unit 138 is a communication unit that transmits operation data to the data server device 200. The in-house communication unit 152 performs wired communication with the operation unit 110. The in-house communication unit 152 communicates with the information processing terminal 120 using a short-range communication method. The short-range communication method is, for example, Wi-Fi (registered trademark) or bluetooth (registered trademark).

[0033] The data server device 200 includes, for example, a data collection unit 210, a diagnosis unit 220, a notification unit 230, and a storage unit 240. The data collection unit 210 acquires operation data and component operation data by communicating with each of the external communication units 150 provided in a plurality of air conditioners 100. The storage unit 240 stores the component-related information and component operation data collected by the data collection unit 210 in association with each other. The diagnosis unit 220 integrates the component values for each condition based on the component-related information stored in the storage unit 240 and diagnoses the life of the component based on the integrated value of the component for each condition. The diagnosis unit 220 may diagnose the life of the component, for example, by comparing the integrated value of the component with the maintenance cycle. The diagnosis unit 220 may diagnose the life of the component, for example, by comparing the integrated value of the component for each condition with the failure history of the component for each condition. The notification unit 230 notifies the diagnosis result by the diagnosis unit 220 to the owner terminal device 300 or the maintenance provider terminal device 400. Update and Update diagnoses the life of the component based on the integrated value of the component for each condition. The diagnosis unit 220 may diagnose the life of the component, for example, by comparing the integrated value of the component with the maintenance cycle. The diagnosis unit 220 may diagnose the life of the component, for example, by comparing the integrated value of the component for each condition with the failure history of the component for each condition. The notification unit 230 notifies the diagnosis result by the diagnosis unit 220 to the owner terminal device 300 or the maintenance provider terminal device 400.

[0034] The diagnosis unit 220 may update the component life information based on the diagnosis result of the component. The diagnosis unit 220 may refer to the replacement / repair history information and update the life of the component when the outdoor unit 10, the indoor unit 20, or the component is replaced or repaired.

[0035] Note that part or all of the operation data and component operation data may be transmitted from the air conditioner 100 to the data server device 200 at a preset time, for each preset period, or when a preset condition is satisfied. The operation data and component operation data managed in the data server device 200 are transmitted from the air conditioner 100 to the data server device 200 at a preset time, for each preset period, or when a preset condition is satisfied, and may not be stored in the outdoor unit 10 or the indoor unit 20.

[0036] Hereinafter, the operation data and the component operation data will be described. FIG. 5 is a diagram showing an example of operation data and component operation data in the first embodiment. The operation data and the component operation data are transmitted, for example, together with a device ID that identifies the air conditioner 100, for each air conditioner 100 External communication unit 138 and collected by the data collection unit 210.

[0037] FIG. 6 is a diagram showing an example of component operation data and component-related information in the first embodiment. The component operation data is transmitted from the communication device 30 to the air conditioner 100 in association with a component ID that uniquely identifies the component, for example. The component operation data is accumulated in the accumulation unit 240 by the data collection unit 210. The component operation data is, for example, the energization time of the outdoor unit 10, the energization time of the indoor unit 20, the Of the operation timeIt includes data such as the integration time. The component operation data is associated with the component-related information. The storage unit 240 stores, for example, by associating the component-related information and the component operation data transmitted corresponding to the same device ID. The component-related information includes model information corresponding to the type of the air conditioner 100, the manufacturing number information that uniquely identifies the air conditioner 100, and the manufacturing number information that uniquely identifies the component, installation-related information such as the piping length of the refrigerant 19, and environmental information indicating the outside air temperature and cold regions, etc.

[0038] FIG. 7 is a diagram showing an example of a reference value corresponding to the component-related information for each component in the first embodiment. The storage unit 240 stores, for each component, a reference value corresponding to the component-related information. The reference value is a value for the diagnosis unit 220 to diagnose the life of the component. The reference value is a value corresponding to the maintenance cycle indicating the time when the life of the component arrives, but is not limited thereto, and may be a value set at the design stage, or a value corresponding to the notification timing before the time when the life of the component arrives. For example, when X hours is registered as the reference value corresponding to the outside air temperature of the compressor 12, and the integration time of the compressor 12 at the outside air temperature reaches X hours, the diagnosis unit 220 can diagnose that the life of the compressor 12 has arrived. The reference value may be a value for the diagnosis unit 220 to diagnose the failure of the component. For example, when N hours, which is the integration time when the compressor 12 failed in another air conditioner 100, is registered as the reference value corresponding to the integration time of the compressor 12, and the integration time of the compressor 12 reaches N hours, the diagnosis unit 220 can diagnose that it notifies an alarm of the failure of the compressor 12.

[0039] FIG. 8 is a diagram showing the relationship among component-related information, component ID, and component operation data in the first embodiment. FIG. 9 is a diagram showing an example of the relationship between the outside air temperature and the integrated time of the compressor 12 in the first embodiment. The storage unit 240 may store, for example, the component ID and component operation data of a component in association with the component-related information. When the storage unit 240 acquires operation data and component operation data, it refers to the component-related information included in the operation data, and registers the component ID and component operation data corresponding to the component-related information registered in the storage unit 240. Thereby, the storage unit 240 can update the component operation data for each component in association with the component-related information. The storage unit 240 can update, for example, the integrated times T1 to T5 of the compressor 12 for each range of the outside air temperature as shown in FIG. 9. Thereby, the diagnosis unit 220 can diagnose the life of the compressor 12 by comparing the integrated times T1 to T5 of the compressor 12 corresponding to the range of the outside air temperature stored in the storage unit 240 with the reference values corresponding to the integrated times of the compressor 12 for each range of the outside air temperature.

[0040] The diagnosis unit 220 may set a weight coefficient for the component-related information. A higher weight coefficient is set for the component-related information with a higher component load. The diagnosis unit 220 sets, for example, a weight coefficient a corresponding to 0°C or lower, a weight coefficient b corresponding to 0 to 10°C, a weight coefficient c corresponding to 10 to 20°C, a weight coefficient d corresponding to 20 to 30°C, and a weight coefficient e corresponding to over 30°C, and increases the weight coefficient for a temperature range with a higher load on the compressor 12. The diagnosis unit 220 may predict the life or failure of a component by calculating a×T1 + b×T2 + c×T3 + d×T4 + e×T5. For example, when the range of the outside air temperature with the highest load on the compressor 12 is 0°C or lower, the weight coefficient a is set to be the highest. For example, when the load on the compressor 12 increases as the piping length of the refrigerant 19 increases, the weight coefficient corresponding to the longest stage among the multiple stages of the divided piping lengths becomes higher.

[0041] The storage unit 240 may change the reference value for diagnosing components based on component-related information. For example, it is assumed that abnormal detection information indicating that the compressor 12 has failed with an accumulated time of Y hours in an environment where the outside air temperature range is 0°C or lower is obtained. The storage unit 240 can update the reference value corresponding to the accumulated time of the compressor 12 in the outside air temperature range of 0°C or lower to a value close to Y hours.

[0042] Hereinafter, more specific examples of operation data and component operation data will be described. The operation data of the air conditioner 100, the component operation data of the outdoor unit 10, and the component operation data of the indoor unit 20 are data that can be used for diagnosing the lifespan or malfunction of the air conditioner 100, and for diagnosing the lifespan or malfunction of the components included in the air conditioner 100. The operation data is data related to the operation of the air conditioner 100, and includes component-related information including the conditions under which the components included in the air conditioner 100 operate. The component-related information includes data related to the overall operation of the air conditioner 100 such as the operation time of the air conditioner 100, data such as the energization time of the outdoor unit 10, and data such as the energization time of the indoor unit 20. The energization time refers to the operation time of electrical components such as the control board and sensors in the outdoor unit 10 and the indoor unit 20. Note that although the energization time of the outdoor unit 10 and the energization time of the indoor unit 20 are the same, when the indoor unit 20 is replaced with a new one, the energization time of the indoor unit 20 and the energization time of the outdoor unit 10 may be different.

The data server device 200 notifies the owner terminal device 300 and the maintenance technician terminal device 400 that the lifespan of the component has arrived, for example, when the integrated value associated with the component-related information exceeds the reference value. The data server device 200 may input the operation data and the component operation data into the prediction unit 254 and predict the lifespan of the component based on the output of the prediction unit 254. The data server device 200 notifies the prediction results to the owner terminal device 300 and the maintenance technician terminal device 400, for example, when there is a component whose lifespan has elapsed or a component whose lifespan will arrive within a predetermined period.

Thus, according to the data server device 200, the lifespan of components with high integrated values in specific operation modes such as cooling or heating can be diagnosed. For example, when the operation time in the cooling mode is longer than that in other operation modes, the integrated value of the drain pump becomes high, and the owner or maintenance technician can be notified that the lifespan of the drain pump arrives earlier than that of other components.

[0057] According to the data server device 200 in the first embodiment, the integrated value of the components is calculated for each temperature range around the outdoor unit Update Thus, Update Based on the integrated values for each temperature range around the outdoor unit obtained, the lifespan of the components can be diagnosed.

[0058] According to the data server device 200 in the first embodiment, the integrated value of the components corresponding to the pipe length of the refrigerant 19 is Update Thus, Update Based on the integrated values obtained, the components can be diagnosed. Thus, according to the data server device 200, the lifespan of the components can be diagnosed in accordance with the actual situation that the load on the components increases as the pipe length of the refrigerant 19 increases.

[0059] According to the data server device 200 in the first embodiment, for each model information of the air conditioner 100, for each manufacturing number information of the air conditioner 100, and for each manufacturing number information of parts, the integrated value of the parts is Update calculated, Update and the life of the parts can be diagnosed based on the calculated integrated value.

Thus, according to the data server device 200, the life of the parts can be diagnosed in accordance with the actual situation that the life of the parts varies depending on the type of the property.

[0061] According to the data server device 200 in the first embodiment, reference values for diagnosing parts for each condition can be set based on the operation data and parts operation data collected from each of the communication devices 30 respectively mounted on a plurality of air conditioners 100. Thus, according to the data server device 200, the life of the parts can be diagnosed based on the comparison with the reference values set using a large number of operation data and parts operation data. As a result, according to the data server device 200, the diagnostic accuracy can be improved.

[0062] According to the data server device 200 in the first embodiment, a weight coefficient is set corresponding to the load of the parts for each condition, the integrated value of the parts corresponding to the condition is multiplied by the weight coefficient, and the multiplied integrated value of the parts is Update calculated, UpdateThe lifespan of components can be diagnosed based on the integrated values of components for each given condition. Thus, according to the data server device 200, even when the load on the components changes depending on conditions such as the outdoor temperature, the lifespan of the components can be diagnosed while emphasizing the integrated value corresponding to the condition with a high load.

[0063] Hereinafter, a second embodiment will be described. In the description of the second embodiment, the same reference numerals are given to the same parts as in the first embodiment. FIG. 12 is a block diagram showing an example of a component inventory management system in the second embodiment. The component inventory management system in the second embodiment is different from the component diagnosis system in the first embodiment in that a component inventory management device 500 and an order terminal 600 are connected to a network NW. The component inventory management device 500 and the order terminal 600 have communication interfaces (not shown) such as NICs and wireless communication modules for connecting to the network NW and the like. The component inventory management device 500 includes an inventory database 510 for managing the inventory of components in the air conditioner 100. The order terminal 600 is a personal computer or the like operated by a person in charge of an ordering organization that orders components.

[0064] FIG. 13 is a diagram showing an example of information included in the inventory database 510 in the second embodiment. The inventory database 510 includes, for example, component inventory information and procurement forecast quantity information. The component inventory information and the procurement forecast quantity information are created, for example, for each installation area where the conditions under which the components included in the air conditioner 100 operate are different. The installation area is, for example, an area where the conditions under which the air conditioner 100 operates are different, such as the ambient temperature around the outdoor unit 10 such as the weather, but is not limited thereto. The component inventory information and the procurement forecast quantity information may be created for each installation condition of the air conditioner 100, such as an air conditioner 100 for a building or a store and an air conditioner 100 for a home. The component inventory information and the procurement forecast quantity information may be created, for example, for each service station in charge of the business of procuring components.

[0065] The parts inventory information is, for example, information in which a model ID, a part ID, and inventory quantity information are associated. The model is, for example, a model corresponding to cold regions. The part ID is, for example, information associated with the part ID included in the part operation data and part-related information shown in FIG. 6. The inventory quantity information is, for example, the parts inventory quantity in the installation area or service station. The procurement forecast quantity information is information indicating the quantity of parts predicted to need to be procured in the future. The procurement forecast quantity information includes, for example, the procurement forecast quantity one month later, the procurement forecast quantity two months later, and the procurement forecast quantity three months later associated with the model ID and the part ID.

[0066] The parts inventory management device 500 collects information indicating the remaining life of the parts from among the parts life information from the data server device 200 and updates the procurement forecast quantity information. The information indicating the remaining life of the parts is the diagnosis result of the parts life by the data server device 200. The diagnosis result includes not only the part ID, but also the integrated value of the parts for each operating condition of the parts and the installation area information of the parts corresponding to the part ID. Thereby, the parts inventory management device 500 can update the procurement forecast quantity information corresponding to the installation area based on the installation area information.

[0067] For example, when the quantity information corresponding to part A1 in the parts inventory management device 500 is "5", the procurement forecast quantity one month later corresponding to part A1 is "10", and the period required to procure part A1 is one month, the parts inventory management device 500 issues an alert. The parts inventory management device 500 transmits, for example, alert information for causing the ordering terminal 600 to display that the quantity of part A1 may run out of stock one month later to the ordering terminal 600. Thereby, the parts inventory management device 500 can enable the ordering organization to grasp in advance the parts that need to be procured and procure part A1 in advance. Furthermore, the parts inventory management device 500 can cause the service station to arrange the parts that may run out of stock before the parts are ordered.

[0068] Furthermore, the component inventory management device 500 may arrange components in advance at the time or place where the air conditioner 100 is frequently used, such as the time or place when the heating operation or the cooling operation is started. For example, in a cold region, based on the life diagnosed from the integrated time of the compressor 12 corresponding to an outside air temperature around the outdoor unit 10 of 0 degrees or lower as a condition for the component to operate, the component inventory management device 500 can cause the ordering terminal 600 to order the compressor 12 before the start time of the heating operation.

[0069] As described above, according to the component inventory management system of the second embodiment, the data server device 200 calculates the integrated value of the components for each condition under which the components included in the air conditioner 100 operate. Update And the component inventory management device 500 Update collects the results of diagnosing the life of the components based on the integrated values of the components for each of the conditions thus calculated. Based on the diagnosis results, the component inventory management device 500 updates the procurement prediction number information indicating the number of components to be procured in the future for each condition and transmits alert information. As a result, the component inventory management device 500 can order the components in advance before the life of the components that reach the end of their life according to the operating conditions of the components included in the air conditioner 100.
