The following describes an embodiment of the present disclosure with reference to the drawings.

<Overall configuration example>
1 is an example of an overall configuration according to an embodiment of the present disclosure. The air conditioning management system 1 includes an air conditioner 10, a server 20, and a terminal 30. The air conditioner 10, the server 20, and the terminal 30 can transmit and receive data to and from each other via any network.

[Air conditioner]
The air conditioner 10 includes one or more outdoor units and one or more indoor units. A unit consisting of one or more outdoor units and one or more indoor units connected by refrigerant piping is called a system (also called a refrigerant system). A building or the like (hereinafter also referred to as a property) in which the air conditioner 10 is installed has one or more systems. In one embodiment of the present disclosure, it is possible to set the ratio of indoor units to be stopped among the indoor units included in the air conditioner 10. For example, it may be possible to set the ratio of indoor units to be stopped among all air conditioners in the property (i.e., air conditioners in all systems), or it may be possible to set the ratio of indoor units to be stopped among each air conditioner in the property (i.e., each system).

[server]
The server 20 is a device that simulates the amount of power consumption of the air conditioner 10. For example, the server 20 is configured from one or more computers.

For example, the server 20 acquires information on the past power consumption of the air conditioner 10 (e.g., the amount of power consumed in one year) from the air conditioner 10. The server 20 also acquires information input to the terminal 30 on the time to stop the air conditioner 10 and the percentage of the air conditioner 10 to be stopped. The server 20 also calculates the amount of power consumption when the air conditioner 10 is stopped at the time input to the terminal 30 for the percentage input to the terminal 30 based on the past power consumption (i.e., the amount of power consumed when the air conditioner 10 is stopped at that percentage at that time). The server 20 also causes the terminal 30 to display the calculated amount of power consumption (i.e., the amount of power consumed when the air conditioner 10 is stopped at that percentage at that time).

[Device]
The terminal 30 is a device into which the time for stopping the air conditioners 10 and the percentage of the air conditioners 10 to be stopped are input. For example, the terminal 30 is a personal computer, a tablet, a smartphone, or the like.

For example, the terminal 30 accepts input from an operator of the terminal 30 (e.g., a person who manages the air conditioners) of the time to stop the air conditioners 10 and the percentage of the air conditioners 10 to be stopped, and transmits this to the server 20. The terminal 30 also receives the results of a simulation of the power consumption of the air conditioners 10 from the server 20 and displays them.

Note that, although this specification mainly describes an embodiment in which the server 20 simulates the amount of power consumption and displays the results of the simulation on the terminal 30, the terminal 30 may also execute at least a part of the processing for simulating the amount of power consumption.

<Hardware Configuration>
2 is a hardware configuration diagram of the server 20 and the terminal 30 according to an embodiment of the present disclosure. The server 20 and the terminal 30 can include a control unit 1001, a main memory unit 1002, an auxiliary memory unit 1003, an input unit 1004, an output unit 1005, and an interface unit 1006. Each of these will be described below.

The control unit 1001 is a processor (e.g., a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), etc.) that executes various programs installed in the auxiliary memory unit 1003.

The main memory unit 1002 includes a non-volatile memory (ROM (Read Only Memory)) and a volatile memory (RAM (Random Access Memory)). The ROM stores various programs, data, etc. required for the control unit 1001 to execute the various programs installed in the auxiliary memory unit 1003. The RAM provides a working area into which the various programs installed in the auxiliary memory unit 1003 are expanded when they are executed by the control unit 1001.

The auxiliary memory unit 1003 is an auxiliary memory device that stores various programs and information used when the various programs are executed.

The input unit 1004 is an input device through which the operator of the server 20 and the terminal 30 inputs various instructions to the server 20 and the terminal 30.

The output unit 1005 is an output device that outputs the internal state of the server 20 and the terminal 30, etc.

The interface unit 1006 is a communication device for connecting to a network and communicating with other devices.

The processing performed by the control unit 1001 is described below.

The control unit 1001 (e.g., the control unit 1001 of the server 20) acquires information on the past power consumption of the air conditioner 10. For example, the control unit 1001 (e.g., the control unit 1001 of the server 20) periodically (e.g., every hour) collects information on the power consumption of the outdoor units of the air conditioner 10 (i.e., the amount of power consumed by the outdoor units of each system) from a communicable device connected to the air conditioner 10, stores the information in a memory unit (main memory unit 1002, auxiliary memory unit 1003), and acquires the stored information on the past power consumption.

[Past power consumption]
Here, the past power consumption will be described. The past power consumption is the amount of power actually consumed by the air conditioner 10. For example, the power consumption is the amount of power consumed over one year. For example, the power consumption is the amount of power consumed by time period (for example, every hour).

For example, the power consumption is the power consumption of the air conditioners 10 of each system installed in the property. For example, the power consumption may be the power consumption of the outdoor unit of the air conditioner (since the power consumption of the indoor unit is smaller than that of the outdoor unit, it is possible to use only the power consumption of the outdoor unit and not the power consumption of the indoor unit in the power consumption simulation), or it may be the power consumption of the indoor unit and the outdoor unit of the air conditioner.

For example, information on the amount of power consumption collected from the air conditioner 10 is managed and stored for each system. The amount of power consumed by the outdoor unit of each system may be stored as the amount of power consumption of that system (the amount of power consumed by the outdoor unit of each system may be apportioned and stored as the amount of power consumption of each indoor unit), or the amount of power consumed by the indoor unit and outdoor unit of each system may be stored as the amount of power consumption of that system.

The control unit 1001 (e.g., the control unit 1001 of the server 20) acquires and sets (stores) information input to the terminal 30 regarding the time to stop the air conditioners 10 and the percentage of the air conditioners 10 to be stopped. For example, the control unit 1001 (e.g., the control unit 1001 of the server 20) acquires and sets (stores) information regarding the time to stop the air conditioners 10 of each system installed in the property specified by the terminal 30 (i.e., the property input to the terminal 30) (i.e., the time to stop each system) and the percentage of the air conditioners 10 to be stopped in each system (i.e., the percentage of the indoor units to be stopped among the indoor units included in each system).

The control unit 1001 (e.g., the control unit 1001 of the server 20) calculates the amount of power consumption that would be consumed if the air conditioner 10 were stopped at the rate acquired by the control unit 1001 (e.g., the control unit 1001 of the server 20) at the time acquired by the control unit 1001 (e.g., the control unit 1001 of the server 20) based on the amount of power consumption in the past acquired by the control unit 1001 (e.g., the control unit 1001 of the server 20). For example, the control unit 1001 (e.g., the control unit 1001 of the server 20) subtracts the amount of power consumed by the air conditioner 10 at the rate of each system at the time the air conditioner 10 of each system is stopped from the amount of power actually consumed by the air conditioner 10 in the past.

The control unit 1001 (e.g., the control unit 1001 of the server 20) causes the power consumption calculated by the control unit 1001 (e.g., the control unit 1001 of the server 20) to be displayed on the terminal 30 or the like. The control unit 1001 (e.g., the control unit 1001 of the server 20) may also display the effect of the reduction in power consumption (e.g., the reduced power consumption (kWh), the reduced electricity bill (yen)).

Methods
FIG. 3 is a flowchart of a simulation process for the amount of power consumption of an air conditioner according to an embodiment of the present disclosure.

In step 1 (S1), the control unit 1001 (e.g., the control unit 1001 of the server 20) acquires information on the past power consumption of the air conditioner 10. For example, the control unit 1001 (e.g., the control unit 1001 of the server 20) periodically (e.g., every hour) collects the power consumption of the outdoor unit of the air conditioner 10 (i.e., the amount of power consumed by the outdoor unit of each system) from a communicable device connected to the air conditioner 10, stores it in a memory unit (main memory unit 1002, auxiliary memory unit 1003), and acquires the stored information on the past power consumption.

For example, the control unit 1001 acquires information on the amount of power consumed by the outdoor units of air conditioners of each system installed in the property specified by the terminal 30 (i.e., the property input to the terminal 30) by time period (e.g., the amount of power consumed over the past year).

In step 2 (S2), the control unit 1001 (e.g., the control unit 1001 of the server 20) acquires and sets (stores) information entered into the terminal 30 regarding the time to stop the air conditioner 10 and the percentage of the air conditioner 10 to be stopped.

For example, the control unit 1001 acquires and sets (stores) information on the time to stop the indoor units of the air conditioners 10 of each system installed in the property S1 (i.e., the stop time for each system) and the percentage of indoor units to be stopped in each system.

In step 3 (S3), the control unit 1001 (e.g., the control unit 1001 of the server 20) calculates the amount of power consumption for the time for which the indoor units are stopped and the ratio of indoor units to be stopped set in S2, based on the past power consumption amount acquired in S1.

For example, the control unit 1001 subtracts the amount of power consumed by the air conditioner 10 in each system of S2 during the time when the air conditioner 10 in each system of S2 is stopped from the amount of power actually consumed by the air conditioner 10 in the past obtained in S1.

In step 4 (S4), the control unit 1001 (e.g., the control unit 1001 of the server 20) causes the power consumption calculated in S3 to be displayed on the terminal 30 or the like. The control unit 1001 (e.g., the control unit 1001 of the server 20) may also display the effect of the reduction in power consumption (e.g., the reduced power consumption (kWh), the reduced electricity bill (yen)).

For example, the control unit 1001 causes the terminal 30 to display the screens described in Figures 4 to 9.

<Bulk setting target>
In one embodiment of the present disclosure, the time to stop and the rate of stopping can be set collectively for each air conditioner (e.g., system). Furthermore, upon receiving an instruction as to whether or not to set an air conditioner as the target of the collective setting (e.g., by clicking on the collective setting exclusion 15 in FIG. 8 ), the control unit 1001 can execute collective setting of the time and rate for the air conditioners (e.g., systems) that are the target of the collective setting. Note that the control unit 1001 does not execute collective setting for air conditioners (e.g., systems) that are not the target of the collective setting, even if an instruction to set them collectively is received.

<Simulation target>
In one embodiment of the present disclosure, an instruction as to whether or not to include each air conditioner (e.g., system) in the power consumption simulation (i.e., the target for calculating the power consumption after reduction) is received (e.g., received through the target setting 18 in FIG. 9 ), and the control unit 1001 can calculate the power consumption of only the air conditioner (e.g., system) that is the target of the calculation. In other words, each system can be excluded from the simulation.

<Screen>
Hereinafter, examples of screens (for example, screens displayed on the terminal 30) will be described with reference to FIGS.

FIG. 4 is an example of a screen according to an embodiment of the present disclosure. For example, screen 110 showing the results of a simulation of reducing the amount of power consumed by air conditioners can include a screen 111 regarding the amount of power consumed by all systems (described in detail in FIG. 7), and a screen 112 regarding the amount of power consumed by each of all systems (described in detail in FIG. 8 and FIG. 9). Furthermore, screen 110 showing the results of a simulation of reducing the amount of power consumed by air conditioners can include property selection 11, effect of reducing the amount of power consumed 12, time setting (all at once) 13 (described in detail in FIG. 5), and ratio setting (all at once) 14 (described in detail in FIG. 6).

For example, an operator of the terminal 30 (e.g., a person who manages the air conditioner) specifies a desired property in property selection 11 on the screen of FIG. 4. In effect of reduction in power consumption 12, the effect of reduction in power consumption (e.g., reduced power consumption (kWh), reduced electricity bill (yen)) is displayed when the air conditioner 10 is stopped for the amount of power actually consumed by the air conditioner 10 in the past at the rate entered into the terminal 30 at the time entered into the terminal 30.

Figure 5 is an example of a screen according to an embodiment of the present disclosure. Specifically, the screen of Figure 4 shows an area (time setting (all at once) 13) for setting the time to stop the air conditioners 10 for all systems at once. The operator of the terminal 30 can input the time to stop the air conditioners of all systems installed in the property specified by the operator (in the example of Figure 5, start: 9 pm to end: 7 am for all systems) and set them all at once.

Figure 6 is an example of a screen according to an embodiment of the present disclosure. Specifically, the screen of Figure 4 shows an area (ratio setting (all at once) 14) for setting the percentage of air conditioners 10 to be stopped for all systems at once. The operator of the terminal 30 can input the percentage of all systems of air conditioners installed in the property specified by the operator (80 percent for all systems in the example of Figure 6) and set it all at once.

Figure 7 is an example of a screen according to an embodiment of the present disclosure. Specifically, in Figure 4, screen 111 regarding the power consumption of all systems is shown. The screen regarding the power consumption of all systems of the air conditioner includes the calculated power consumption (i.e., the power consumption when the air conditioner 10 is stopped at the time input to the terminal 30 and the rate input to the terminal 30) and the past power consumption (i.e., the amount of power actually consumed by the air conditioner 10 in the past).

As shown in FIG. 7, the past power consumption (in the example of FIG. 7, actual results for the past year (annual power consumption (kWh))) of each system (systems A, B, C, D, E, F, G, H, I, J, K, L, M, N, O) at the time specified to be displayed (in the example of FIG. 7, display time start: 21:00 to end: 07:00) and the power consumption (in the example of FIG. 7, simulation results (annual power consumption (kWh))) when the air conditioners are stopped at the specified time for the specified percentage of the past power consumption are displayed.

In addition, the power consumption of some of the air conditioners in multiple systems installed in the property may be displayed, rather than the power consumption of all air conditioners in the property. For example, only the air conditioners in the systems that rank high in a predetermined ranking (e.g., in order of highest past power consumption, highest power consumption after reduction, greatest effect of power consumption reduction, etc.) may be displayed.

Figures 8 and 9 show the screens 112 in Figure 4 for the power consumption of each of all systems (when the system is the subject of a simulation (Figure 8) and when the system is not the subject of a simulation (Figure 9)). The screen for the power consumption of each of all air conditioner systems includes the past power consumption by system and time period. Each will be explained below.

Figure 8 is an example of a screen according to an embodiment of the present disclosure. Specifically, in Figure 4, a screen 112 for the power consumption of each system of all systems (when it is the target of the simulation) is shown. The operator of the terminal 30 (e.g., the person who manages the air conditioners) can specify whether or not to exclude from the target of the collective setting in the collective setting exclusion 15. The operator of the terminal 30 (e.g., the person who manages the air conditioners) can specify the time to stop the air conditioners of each system (system A in the example of Figure 8) in the time setting (for each system) 16. The operator of the terminal 30 (e.g., the person who manages the air conditioners) can specify the proportion of the air conditioners to be stopped in each system (system A in the example of Figure 8) in the ratio setting (for each system) 17. Note that the power consumption (kWh) for the past year and the effect of reducing the power consumption (kWh) may be displayed for each system.

Figure 9 is an example of a screen according to an embodiment of the present disclosure. Specifically, in Figure 4, a screen 112 is shown regarding the power consumption of each system of all systems (when not subject to simulation). The operator of the terminal 30 (e.g., a person who manages the air conditioners) can specify whether or not to exclude a system from the target of the power consumption simulation in the target setting 18.

<Power consumption correction>
Hereinafter, the correction of the power consumption amount will be described with reference to FIGS.

In one embodiment of the present disclosure, the control unit 1001 can correct the amount of power consumption when the air conditioner is started after the time to stop the air conditioner has elapsed, and calculate the amount of power consumption when the air conditioner is stopped for the proportion input to the terminal 30 at the time input to the terminal 30. Specifically, the control unit 1001 adds the amount of power consumption when the air conditioner is started after being stopped (i.e., the amount of power consumption that would not have occurred if the air conditioner had not been stopped) to calculate the amount of power consumption when the air conditioner 10 is stopped for the proportion input to the terminal 30 at the time input to the terminal 30.

Figure 10 is a diagram for explaining the correction of power consumption according to an embodiment of the present disclosure. The "power consumption" in Figure 10 indicates the power consumption for each time period in the past (in the example of Figure 10, the "time" from midnight onwards, from 1:00 am onwards, ..., from 10:00 pm onwards, and from 11:00 pm onwards). The time for stopping the air conditioners is set to be from 11:00 pm onwards to 7:00 am the following day. In addition, the proportion x of the air conditioners to be stopped is set to 0.8 (i.e., the proportion β (= 1 - x) of the power consumption after reduction = 0.2).

The simulation result for the time to shut down the air conditioner is calculated by multiplying the past power consumption by the percentage of power consumption after reduction (β) (i.e., 1 - percentage of air conditioners to be shut down x).

The simulation results for the times when the air conditioner is not shut down, other than when the air conditioner is started, are the same as the past power consumption amounts.

The simulation results for the time when the air conditioner is started (from 7:00 in the example of Figure 10) during which the air conditioner is not stopped are calculated by adding the amount of power consumption that is expected to occur when the air conditioner is started to the amount of power consumption in the past.

For example, the amount of power consumption expected to occur when starting an air conditioner is calculated as "past power consumption during a specified time period before start-up x percentage of air conditioners to be started x weighting coefficient according to the difference between the start-up time and the specified time."

For example, the weighting factor α1 one hour before the start is set to 0.9, the weighting factor α2 two hours before the start is set to 0.3, and the weighting factor α3 three hours before the start is set to 0.1.
(1) 1 hour before start-up (i.e., from 6:00 a.m.): Past power consumption 1 hour before start-up (i.e., 30) × Proportion of air conditioners to be started (i.e., 0.8) × Weighting coefficient α1 (i.e., 0.9)
(2) 2 hours before start (i.e., from 5:00 onward): past power consumption 2 hours before start (i.e., 20) × ratio of air conditioners to be started (i.e., 0.8) × weighting coefficient α2 (i.e., 0.3)
(3) 3 hours before start-up (i.e., from 4:00 a.m.): past power consumption 3 hours before start-up (i.e., 10) × ratio of air conditioners to be started (i.e., 0.8) × weighting coefficient α3 (i.e., 0.1)
The simulation result when the air conditioner is started (from 7:00 in the example of Figure 10) will be the past power consumption (i.e., 40) plus the values of (1), (2), and (3) above (i.e., 67.2).

Figure 11 is a diagram for explaining the correction of power consumption according to one embodiment of the present disclosure. Figure 11 is a graph showing the numerical values of Figure 11.

As described above, according to the embodiment of the present disclosure, the control unit 1001 (e.g., the control unit 1001 of the server 20) of the air conditioning management system 1 including the server 20 and the terminal 30 acquires information on the past power consumption of the air conditioner 10 (e.g., acquires the power consumption of the outdoor unit of each system as the power consumption of that system), acquires information on the time to stop the air conditioner 10 (e.g., the time for each system) and the percentage of the air conditioner 10 to be stopped (e.g., the percentage of the indoor units to be stopped for each system) input to the terminal 30, calculates the power consumption when the air conditioner 10 is stopped at that percentage at that time based on the past power consumption, and displays the calculated power consumption (e.g., displays on the terminal 30). This makes it possible to accurately simulate the power consumption of the air conditioner 10 when there are air conditioners 10 that can be stopped and air conditioners 10 that should not be stopped.

Preferably, the control unit 1001 of the air conditioning management system 1 corrects the amount of power consumption when the air conditioner 10 is started after the time for stopping the air conditioner 10 has elapsed, and calculates the amount of power consumption when the air conditioner 10 is stopped at that rate during that time. This allows the amount of power consumption when the air conditioner 10 is started after being stopped to be reflected, allowing for an accurate simulation.
