Figure 1 is a block diagram showing the configuration of one embodiment of an air conditioning equipment management system in this embodiment. The air conditioning equipment management system 10 is configured by connecting a monitoring device 100 attached to air conditioning equipment, for example, an indoor unit or an outdoor unit of a heating and cooling equipment, a server 200 that receives and processes information from the monitoring device 100, and a management terminal 300 that functions as an air conditioning equipment management device for managing the air conditioning equipment management system 10, via a communication line such as the Internet.

The monitoring device 100 is attached to the air conditioning equipment to be monitored, and has a function for acquiring data related to the air conditioning equipment, such as data indicating the operating status and error codes, from the air conditioning equipment to be monitored, and transmitting the acquired data to the server 200 via a communication line. In this embodiment, the monitoring device 100 is composed of, for example, a circuit board and communication equipment, and is attached to the indoor unit of a heating and cooling equipment or the outdoor unit of a heating and cooling equipment.

The server 200 receives data on the operating status and error codes of the air conditioning equipment to be monitored from the monitoring device 100, and executes processing to transmit the received data to the management terminal 300. FIG. 2 is a block diagram showing the configuration of one embodiment of the server 200 in this embodiment. The server 200 includes a communication module 201, a control device 202, and a recording device 203.

The communication module 201 includes a module for connecting the server 200 to a communication line such as the Internet, wirelessly or by wire. The server 200 communicates with the monitoring device 100 and the management terminal 300 by connecting to the Internet via the communication module 201.

The control device 202 is made up of a CPU, memory, and other peripheral circuits, and controls the entire server 200. The memory that makes up the control device 203 is, for example, a volatile memory such as an SDRAM. This memory is used as a work memory for the CPU to expand a program when the program is executed, and as a buffer memory for temporarily recording data. For example, data received via the communication module 201 is temporarily recorded in the buffer memory.

The recording device 203 is a recording device for recording various data stored by the server 200, program data to be executed by the control device 202, etc., and may be, for example, a hard disk drive (HDD) or a solid state drive (SSD). The program data recorded in the recording device 203 is provided by being recorded on a recording medium such as a CD-ROM or DVD-ROM, or provided via a network, and the user can install the acquired program data in the recording device 203, thereby enabling the control device 202 to execute the program.

The management terminal 300 may be a terminal owned by a person, company, or organization that manages the air conditioning equipment management system 10, such as a smartphone, tablet terminal, or personal computer. Figure 3 is a block diagram showing the configuration of one embodiment in which a personal computer is used as the management terminal 300. The management terminal 300 includes an operating member 301, a connection interface 302, a control device 303, a recording device 304, and a display device 305.

The operating members 301 include various devices, such as a keyboard and a mouse, that are operated by the operator of the management terminal 300.

The connection interface 302 is an interface for connecting the management terminal 300 to a communication line such as the Internet, and may be, for example, a wired LAN module for connecting to the Internet via a wire, or a wireless LAN module for connecting to the Internet wirelessly. In this embodiment, the management terminal 300 communicates with the server 200 via the connection interface 302.

The control device 303 is made up of a CPU, memory, and other peripheral circuits, and controls the entire management terminal 300. The memory that makes up the control device 303 is, for example, a volatile memory such as an SDRAM. This memory is used as a work memory for the CPU to expand programs when the programs are executed, and as a buffer memory for temporarily recording data. For example, data read via the connection interface 302 is temporarily recorded in the buffer memory.

The recording device 304 is a recording device for recording various data stored by the management terminal 300, data of programs to be executed by the control device 303, and the like, and may be, for example, a hard disk drive (HDD) or a solid state drive (SSD). The program data recorded in the recording device 304 is provided by being recorded on a recording medium such as a CD-ROM or DVD-ROM, or provided via a network, and the user can install the acquired program data in the recording device 304, thereby enabling the control device 303 to execute the program.

The display device 305 is, for example, an LCD monitor, and displays various information output from the control device 303.

In the air conditioning equipment management system 10 in this embodiment, data indicating the operating status and error code data acquired by the monitoring equipment 100 attached to the air conditioning equipment to be monitored are transmitted to the server 200 via a communication line. In the server 200, the control device 202 transmits the data received from the monitoring equipment 100 to the management terminal 300. The management terminal 300 then executes processing to manage the air conditioning equipment to be monitored based on the data indicating the operating status and error code data of the air conditioning equipment to be monitored received via the server 200. The monitoring equipment 100 periodically acquires data indicating the operating status at a preset time interval, for example, once an hour, and transmits it to the server 200. The error code is also transmitted to the server 200 when an error such as a breakdown occurs in the air conditioning equipment. The following mainly describes the content of the processing executed by the management terminal 300.

First, the data indicating the operating status of the monitored air conditioning equipment acquired by the monitoring device 100 will be described. The data indicating the operating status of the monitored air conditioning equipment includes indoor unit data, system data, and individual outdoor unit data. The indoor unit data includes information on room temperature (control board sensor), room temperature (remote control display), indoor suction temperature, indoor coil temperature, indoor coil temperature, indoor blowing temperature, and indoor PMV opening. The system data includes information on the number of connected indoor units, total horsepower of connected indoor units, number of connected outdoor units, and total horsepower of outdoor units. The individual outdoor unit data includes information on compressor 1 discharge temperature, compressor 2 discharge temperature, high pressure sensor detected pressure, low pressure sensor detected pressure, suction temperature, outdoor coil temperature, liquid side temperature, outdoor air temperature, low pressure saturation temperature, compressor 1 current, compressor 2 current, PMV 1+2 opening, compressors 1 and 2 ON/OFF, outdoor fan mode, and outdoor unit horsepower. Note that the data contents indicating the operating status of the air conditioning equipment being monitored described here are merely examples, and the data acquired by the monitoring device 100 is not limited to these.

The operator of the management terminal 300 creates a ledger by registering in advance information on air conditioning equipment to be monitored by the air conditioning equipment management system 10. For example, when registering air conditioning equipment installed in a store, information on the outdoor unit and indoor unit installed in the store is registered in advance. There are no particular limitations on the method of registering air conditioning equipment information, but for example, the control device 303 may import CAD or PDF drawing data and process the data, or may read a two-dimensional code to identify equipment information and process the data. The ledger data is recorded in the recording device 304, and when information on air conditioning equipment to be monitored is newly registered, the control device 303 adds it to the ledger data and registers it. This completes the ledger, which registers information such as the location where the air conditioning equipment to be monitored is installed, the model number, and product details.

The operator of the management terminal 300 can operate the management terminal 300 to input information about the location of the air conditioning equipment registered in the ledger. Information about the equipment location can include, for example, climate information for the area in which the air conditioning equipment is installed, the direction in which the air conditioning equipment is installed, information about the location of the air conditioning equipment, and the estimated annual operating hours of the air conditioning equipment. When information about the equipment location is input, the control device 303 adds the input information to the ledger and updates the ledger.

Based on the ledger data, the control device 303 can predict when air conditioning equipment will require updating work, the risk of breakdowns occurring, and so on. For example, if air conditioning equipment requires updating work every 10 years, the control device 303 can notify the user when the time for updating work is approaching, or when the risk of breakdowns has increased. In this way, by predicting breakdowns and the risk of breakdowns in advance, and proposing expected update times, trouble during peak times can be avoided. Note that generation AI may also be used to predict when updating work will be required, the risk of breakdowns occurring, and so on.

In addition, based on the scanned drawings, etc., the amount of fluorocarbon filled in the air conditioning equipment can be associated with and registered in the ledger. In this case, if the control device 303 automatically calculates the interval for fluorocarbon inspections by a qualified person and registers this in the ledger, it will be possible to comply with regulations. For example, the ledger can be used to ascertain the serial number, making it possible to check the inventory of parts in the future. The ledger also identifies the year of manufacture and installation date, making it possible to propose replacement work at an appropriate time. It can also comply with national refrigerant regulations, and can provide warnings and alerts for replacement based on information on regulations for fluorocarbon gas types. Furthermore, the registered ledger can also be used as an equipment ledger for each store, so it can also be used for asset management.

When the control device 303 detects that a failure or error has occurred in the monitored air conditioning equipment based on data indicating the operating status of the monitored air conditioning equipment and error code data received via the server 200, it notifies a pre-designated contact. For example, the email address of the facility where the air conditioning equipment is installed or the maintenance company that maintains the air conditioning equipment may be registered as the contact.

When the control device 303 receives from the server 200 an error code output from the air conditioning equipment being monitored, it notifies a pre-registered contact of the contents of the error code. This makes it possible to notify the facility where the air conditioning equipment is installed or a maintenance company that an error has occurred in the air conditioning equipment. Furthermore, when the control device 303 detects a possible malfunction in the air conditioning equipment based on data indicating the operating status of the air conditioning equipment being monitored received from the server 200, it notifies a pre-registered contact that the air conditioning equipment may have malfunctioned. At this time, the notification may include data indicating the operating status of the air conditioning equipment where the malfunction has occurred or an error code. This makes it possible to notify the facility where the air conditioning equipment is installed or a maintenance company that there may be a malfunction in the air conditioning equipment.

The control device 303 monitors data received from the server 200 indicating the operating status of the monitored air conditioning equipment, and determines that there are signs of an impending malfunction in the air conditioning equipment in the following cases, for example, and notifies the occurrence of the malfunction. If the compressor discharge temperature is below a specified value, the compressor discharge pressure is below a specified value, and the outdoor unit coil temperature (heat exchanger temperature) is below a specified value, the control device 303 determines that there is a high possibility that the compressor has malfunctioned. In this case, there may be a refrigerant leak from the piping or the compressor, so the signs of compressor malfunction can be detected.

Furthermore, if the coil temperature (heat exchanger temperature) of the outdoor unit is outside the specified value, and the rotation of the opening degree of the expansion valve (PMV) of the outdoor unit is outside the specified value, and the coil temperature (heat exchanger temperature) of the indoor unit is outside the specified value and the rotation of the opening degree of the expansion valve (PMV) of the indoor unit is outside the specified value, the control device 303 determines that there is a high possibility that the heat exchanger of the outdoor unit or the indoor unit is malfunctioning. In this case, for example, there may be a refrigerant leak from the heat exchanger or poor heat transfer due to corrosion of the heat exchange fins, so it is possible to detect signs of malfunction of the heat exchanger.

The control device 303 also detects that defrost operation may not start during heating if the compressor discharge temperature and pressure do not increase, the outdoor unit coil temperature (heat exchanger temperature) is below the low temperature side, and the outdoor air temperature is below the low temperature side of the operating range. In this case, for example, defrost operation may not start during heating due to reduced ventilation performance of the heat exchange fins of the indoor unit or reduced ventilation performance due to snow accumulation around the outdoor unit, so it is possible to detect signs of failure in defrost operation during heating.

In addition, the operating data of the air conditioning equipment is constantly measured at specified intervals and the data is sent to the management terminal 300, so the control device 303 can immediately detect fluorocarbon gas leaks. When the control device 303 detects a fluorocarbon gas leak, it notifies a pre-registered contact that a fluorocarbon gas leak has occurred. Since fluorocarbon gas leaks require particular vigilance, the air conditioning equipment may be automatically shut down when an error occurs, or the air conditioning equipment may be shut down from the management terminal 300. The use of the air conditioning equipment management system 10 in this embodiment can also accommodate exemptions from simple inspections stipulated in the Fluorocarbon Restraint Act, as well as the storage of evidence.

Conventionally, when an air conditioning device malfunctioned, the customer had to call or email the manufacturer or maintenance company from where the device was installed to request a response. In contrast, by using the air conditioning device management system 10 in this embodiment, a pre-registered contact can be automatically notified when an air conditioning device malfunctions or when signs of an impending malfunction are detected. Also, conventionally, each air conditioning device manufacturer had a system for sending error codes to contractors and customers by attaching their own device, but by using the air conditioning device management system 10, any manufacturer can notify of malfunctions.

In addition, because notifications of malfunctions are sent to designated contractors such as maintenance companies, the contractor's workers can rush to the site immediately without waiting for contact from the customer at the location where the air conditioning equipment is installed. Since responding to refrigerant gas leaks is particularly urgent, being able to send notifications directly to contractors is extremely meaningful. This allows freon gas leaks to be repaired quickly, preventing accidents and ozone layer destruction.

In addition, conventionally, a maintenance company staff member would visit the facility where the air conditioning equipment was installed, identify the installation location, and then begin measuring error numbers and operating data to determine whether there was a malfunction and then bring parts to carry out repairs at a later date. However, by using the air conditioning equipment management system 10 in this embodiment, the maintenance company staff member can grasp the data and error codes indicating the operating status of the air conditioning equipment that has malfunctioned in advance, and can determine which equipment (model number and system) is malfunctioning before arriving at the site. Furthermore, the maintenance company staff member can prepare the necessary parts in advance based on the operating data and error numbers, so they can head to the site with the parts in hand. This saves time and manpower, and since the parts are prepared in advance, repairs can be made on the spot.

In addition, the notification of the occurrence of the malfunction can be sent to the facility where the air conditioner is installed, so that the people in the facility where the air conditioner is installed can be aware of the occurrence of the malfunction. Conventionally, when a malfunction occurs in an air conditioner, only an error code is displayed on the remote control, etc., making it difficult to understand the details of the malfunction. In this embodiment, the control device 303 can include information in the notification as to what is malfunctioning and what action should be taken on the spot, so that the people in the facility where the air conditioner is installed can understand the details of the malfunction and how to deal with the malfunction. If a generating AI is introduced when notifying the malfunction, it will be possible to provide countermeasures and estimated costs required for the malfunction in a conversational format. Furthermore, if a generating AI is introduced, it will be possible to accept calls even at night or during holidays.

Figure 4 is a flowchart showing the flow of the driving data transmission process executed by the monitoring device 100 in this embodiment. The process shown in Figure 4 is executed by a control circuit (not shown) as a program that is activated at the timing of transmitting data indicating the driving status, for example, once an hour.

In step S10, a control circuit (not shown) acquires data indicating the operating status, i.e., operating data, from the air conditioning equipment to be monitored and transmits it to the server 200. Then, the process ends.

Figure 5 is a flowchart showing the flow of the error code transmission process executed by the monitoring device 100 in this embodiment. The process shown in Figure 5 is executed by a control circuit (not shown) as a program that is started when it is detected that the air conditioning device to be monitored has output an error code.

In step S110, the control circuit (not shown) transmits the error code output from the air conditioning device being monitored to the server 200. Then, the process ends.

Figure 6 is a flowchart showing the flow of processing executed by the server 200 in this embodiment. The processing shown in Figure 6 is executed by the control device 202 as a program that is started when data indicating the operating status or error code data is received from the monitoring device 100.

In step S210, the control device 202 transmits the data received from the monitoring device 100 to the management terminal 300 as described above. Then, the process ends.

Figure 7 is a flowchart showing the flow of processing executed by the management terminal 300 in this embodiment. The processing shown in Figure 7 is executed by the control device 303 as a program that is started when data indicating the operating status or error code data is received from the server 200. Note that in Figure 7, it is assumed that the registration of the above-mentioned ledger has already been completed.

In step S310, the control device 303 determines whether or not an error code has been received from the server 200. If the determination in step S310 is negative, the process proceeds to step S330. On the other hand, if the determination in step S310 is positive, the process proceeds to step S320.

In step S320, the control device 303 notifies the preregistered contact of the contents of the error code received from the server 200, as described above. Then, the process proceeds to step S330.

In step S330, the control device 303 performs a failure determination process to monitor the data indicating the operating status of the monitored air conditioning equipment received from the server 200, as described above, and to determine whether there are signs of a failure in the air conditioning equipment. Then, the process proceeds to step S340.

In step S340, the control device 303 determines whether or not the determination process in step S330 has detected a possible malfunction in the air conditioning equipment. If the determination in step S340 is negative, the process ends. On the other hand, if the determination in step S340 is positive, the process proceeds to step S350.

In step S350, the control device 303 notifies the preregistered contacts that there is a possibility of a malfunction in the air conditioning equipment, as described above. Then, the process ends.

According to the embodiment described above, the following advantageous effects can be obtained.
(1) The monitoring device 100 acquires data relating to the air conditioning equipment, such as data indicating the operating status and error codes, from the air conditioning equipment to be monitored, and in the management terminal 300, when the control device 303 receives an error code output from the air conditioning equipment to be monitored, it notifies a pre-registered contact of the contents of the error code, and when it detects a possibility of a malfunction in the air conditioning equipment based on the data indicating the operating status of the air conditioning equipment to be monitored, it notifies a pre-registered contact of the possibility of a malfunction in the air conditioning equipment. This allows for rapid notification when an error occurs in the air conditioning equipment or when a malfunction is suspected.

(2) The air conditioning equipment management system 10 includes a server 200 that receives information from the monitoring equipment 100 and transmits it to the management terminal 300. The monitoring equipment 100 transmits data related to the air conditioning equipment to the server 200, and the management terminal 300 receives the data related to the air conditioning equipment from the server 200 and processes it. This allows data related to the air conditioning equipment to be transmitted from the monitoring equipment 100 to the management terminal 300 via, for example, a cloud server.

(3) The monitoring device 100 is configured to acquire data indicating the driving status at a preset time interval and transmit the data to the server 200. This allows data to be automatically transmitted at a predetermined time interval.

(4) The control device 303 performs processing to detect possible malfunctions in the air conditioning equipment based on data indicating the operating status of the air conditioning equipment being monitored, and as a result, when it detects a possible malfunction in the air conditioning equipment, it notifies a pre-registered contact. In this way, it is possible to detect and notify possible malfunctions in the air conditioning equipment.

(5) Based on data showing the operating status of the air conditioning equipment being monitored, the control device 303 determines that there is a high possibility that the compressor is malfunctioning if the compressor discharge temperature is below a specified value, the compressor discharge pressure is below a specified value, and the outdoor unit coil temperature (temperature of the heat exchanger) is below a specified value. This makes it possible to detect signs of compressor malfunction, since there may be a refrigerant leak from the piping or the compressor.

(6) The control device 303 is configured to determine that there is a high possibility that the heat exchanger of the outdoor unit or the indoor unit is malfunctioning if the coil temperature (heat exchanger temperature) of the outdoor unit is outside of a specified value, the rotation of the opening degree of the expansion valve (PMV) of the outdoor unit is outside of a specified value, and the coil temperature (heat exchanger temperature) of the indoor unit is outside of a specified value and the rotation of the opening degree of the expansion valve (PMV) of the indoor unit is outside of a specified value. This makes it possible to detect signs of malfunction of the heat exchanger, for example, because there is a possibility of poor heat transfer due to a refrigerant leak from the heat exchanger or corrosion of the heat exchange fins.

(7) The control device 303 detects that defrost operation may not start during heating if the compressor discharge temperature and pressure do not increase, the outdoor unit coil temperature (heat exchanger temperature) is below the low temperature side, and the outdoor air temperature is below the low temperature side of the operating range. This makes it possible to detect signs of failure in the defrost operation during heating, since defrost operation may not start during heating due to, for example, reduced ventilation performance of the heat exchange fins of the indoor unit or reduced ventilation performance due to snow accumulation around the outdoor unit.

(8) When the control device 303 detects a fluorocarbon gas leak from an air conditioner, it notifies a pre-registered contact that a fluorocarbon gas leak has occurred. This allows for immediate detection and notification of a fluorocarbon gas leak, which can help prevent accidents and ozone layer destruction.

--Variations--
The air conditioning equipment management system 10 according to the embodiment described above can also be modified as follows.
(1) In the above embodiment, a notification of a failure is sent to a designated contractor such as a maintenance company, and therefore the maintenance company staff can bring the necessary parts in advance based on the operation data and the error number and head to the site. In this case, the maintenance company staff may be able to check the inventory status of the air conditioner parts in real time. This allows the maintenance company staff to obtain information on the failure details of the air conditioner, the error number, and the inventory status of the parts. Furthermore, if the maintenance company staff can grasp the inventory status of the parts, they can deal with equipment that has discontinued parts by only proposing renewal work, and do not need to go to judge the failure, so that improvement in work efficiency can be expected. For example, for equipment that is more than 10 years old, renewal work can be proposed, so that sudden responses in the summer and unnecessary failure repairs can be avoided.

(2) In the above-described embodiment, an example was described in which the control device 303 monitors data indicating the operating status of the monitored air conditioning equipment received from the server 200, and detects signs of compressor failure, signs of heat exchanger failure, and signs of failure in defrosting operation during heating. However, the signs of failure to be detected are not limited to these, so long as they are failures that can be detected based on data indicating the operating status of the monitored air conditioning equipment.

As long as the characteristic functions of the present invention are not impaired, the present invention is not limited to the configurations in the above-described embodiments. In addition, the present invention may be configured by combining the above-described embodiments with multiple modified examples.
