Description

The present invention relates to a communication terminal device for operating an air conditioner via a communication network, and an air conditioning system.

In recent years, there is a technique for operating the start and stop of operation of an air conditioner from a communication terminal device by downloading a dedicated application to a communication terminal device such as a smartphone (for example, Patent Document 1).

Further, in household electronic devices (home appliances) including air conditioners, various measures are taken to reduce power consumption (energy saving). As a technology to reduce the power consumption of the air conditioner, it corresponds to the stop time when the amount of power required to temporarily stop and then restart the operation to reach the set temperature and the amount of power when the operation is continued are the same. There is a technique for calculating the branching time (branching point time) to be performed and notifying the user (for example, Patent Documents 2 and 3). By notifying the branch time, the user can reduce the power consumption by selecting continuation if the scheduled time to leave the room is shorter than the branch time and selecting stop if the scheduled time is longer than the branch time.

In Patent Documents 2 and 3, no study is made on the timing of notification for effectively using the branch time. Therefore, in the configurations of Patent Documents 2 and 3, it cannot be said that the function of notifying the branch time is effectively used, and there is a problem that the opportunity to save energy is missed.

For example, in Patent Document 3, the branch time is displayed on a remote controller or a communication terminal device, or is notified by voice output, but the timing of the notification is always displayed or when there is a request from the user. It is stated that only display is displayed.

However, in the configuration where the display is always displayed, the interest in the branch time is diminished, and there is a risk that the opportunity to save energy by using the information on the branch time is lost. Further, in the configuration of displaying only when the user requests it, it is not displayed unless the user requests it, so that the user may not even notice the existence of the function of notifying the branch time.

One aspect of the present invention is to realize a communication terminal device and an air conditioning system capable of more effectively saving energy by using information on branch time.

In order to solve the above problems, the communication terminal device according to one aspect of the present invention consumes power and operates to make the operation of the air conditioner the same as the room temperature before the stop after temporarily stopping the operation.

In order to solve the above problems, the communication terminal device according to another aspect of the present invention consumes power and operates to make the operation of the air conditioner once stopped and then restarted to be the same as the room temperature before the stop. A communication terminal device including a notification unit for notifying a branch time corresponding to a stop time at which the power consumption becomes the same when continued, and a notification control unit for notifying the notification unit of the branch time. The notification control unit notifies the branch time immediately before the time when the operation of the air conditioner is estimated to be stopped.

In order to solve the above problems, the program according to one aspect of the present invention is a program for operating a computer as a communication terminal device according to one aspect of the present invention, and is the broadcast control unit and the input control unit. , And a program for operating the computer as the communication control unit.

In order to solve the above problems, the air conditioning system according to one aspect of the present invention is connected to an air conditioner, a server connected to the air conditioner by a communication network, and the server and the communication network. The operation of the communication terminal device for operating the air conditioner via the server and the air conditioner provided in the air conditioner, the server or the communication terminal device is temporarily stopped and then restarted before the stop. The air conditioner or the communication terminal device is provided with a branch time calculation unit that calculates a branch time corresponding to a stop time in which the power consumption for making the room temperature the same and the power consumption when the operation is continued are the same.

[First Embodiment]
Hereinafter, an embodiment of the present invention will be described in detail. FIG. 1 is a diagram showing a schematic configuration of an air conditioning system 30 according to the present embodiment. As shown in FIG. 1, the air conditioning system 30 includes an air conditioner 1 installed in a user's house 31, a server 40, and a communication terminal device 50 of the user of the air conditioner 1, each of which is via a communication network 32. It is connected. Note that FIG. 1 shows a portion of the air conditioning system 30 relating to a certain user's house 31, and in reality, a plurality of air conditioners in the plurality of user's houses are connected to the server 40.

The air conditioner 1 connects to the communication network 32 and communicates with the server 40. The user's house 31 is provided with a wireless LAN (Wireless Local Area Network) that forms part of the communication network 32. The relay station of the wireless LAN is connected to the communication network 32 including the Internet. The relay station is a communication device such as a WiFi (registered trademark) router or a WiFi (registered trademark) access point. Although the configuration including the Internet is illustrated here as the communication network 32, a telephone line network, a mobile communication network, a CATV (CAble TeleVision) communication network, a satellite communication network, or the like can also be used. The communication terminal device 50 and the Internet in the communication network 32 are connected by using a 4G (4th Generation), LTE (Long Term Evolution), a home or public WiFi (registered trademark) access point, or the like.

The server 40 registers the combination of the air conditioner 1 and the communication terminal device 50. The server 40 enables the operation (remote control) of the air conditioner 1 by the communication terminal device 50 in which the combination is registered. The server 40 receives operation data, room temperature, outside air temperature, and the like indicating the operation contents of the air conditioner 1 from the air conditioner 1. Further, the server 40 is also connected to an external server (not shown) via the communication network 32, and the outside air temperature can be acquired from the weather forecast system.

The communication terminal device 50 is a communication terminal device such as a smartphone or tablet of the user of the air conditioner 1, and an application for operating the air conditioner 1 is downloaded. In the case of a short distance such as in the user's house 31, the communication terminal device 50 and the air conditioner 1 may be connected by Bluetooth (registered trademark) or the like without going through the server 40.

The air conditioner 1 is a device that performs air conditioning operation (air conditioning operation), and when it receives an instruction from the communication terminal device 50 via the server 40, it cools, heats, blows air, dehumidifies, and air based on the instruction. Perform air conditioning operation such as cleaning. As described above, the air conditioner 1 transmits operation data, room temperature, outside air temperature, and the like to the server 40. The operation data includes set temperature, operation type (cooling, heating, ventilation, dehumidification, air purification, etc.), operation mode (automatic mode, wind power setting mode, energy-saving operation mode, etc.), power on (operation start), power off (power off (operation start)). Information such as stop) is included.

FIG. 2 is a block diagram showing the configuration of the air conditioning system 30. As shown in FIG. 2, the air conditioner 1 includes an air conditioner control unit 10, a communication unit 21, a storage unit 22, an air conditioning operation unit 23, an outdoor temperature sensor 24, an indoor temperature sensor 25, and a remote controller (hereinafter, simply referred to as a remote controller). It is equipped with 26 and the like.

The communication unit 21 enables communication between the air conditioner 1 and an external device. The storage unit 22 stores various information / programs necessary for the operation of the air conditioner 1. The air-conditioning operation unit 23 has functions such as cooling, heating, ventilation, dehumidification, deodorization, and ventilation, and performs these operations as appropriate under the control of the air-conditioning operation control unit 11 of the air conditioner control unit 10.

The outdoor temperature sensor 24 detects the outside air temperature, which is the temperature of the outside air, and the indoor temperature sensor 25 detects the room temperature, which is the temperature of the room (room) which is an air-conditioned space. Although not shown, the air conditioner 1 includes an indoor unit installed indoors to blow out conditioned air and an outdoor unit installed outdoors to exchange heat with the outside air. Normally, the indoor temperature sensor 25 is mounted on the indoor unit, and the outdoor temperature sensor 24 is mounted on the outdoor unit.

The remote controller 26 has an operation start (operation ON), an operation stop (operation OFF), an operation type (cooling, heating, dehumidification, ventilation, air purification, etc.) and an operation mode (automatic mode, wind force setting mode, energy saving) for the air conditioner 1. Accepts user instructions such as operation mode) and change of set temperature. The accepted user instruction is transmitted from the remote controller 26 to the air conditioner 1.

The air conditioner control unit 10 controls the operation of each unit of the air conditioner 1. The air conditioner control unit 10 is composed of a computer device composed of, for example, an arithmetic processing unit such as a CPU or a dedicated processor, and controls the operation of each part of the air conditioner 1 according to an information / program stored in the storage unit 22. do.

The air conditioner control unit 10 is constructed with an air conditioner operation control unit 11. The air-conditioning operation control unit 11 controls the air-conditioning operation unit 23 to perform air-conditioning operations such as cooling, heating, ventilation, dehumidification, and air cleaning. The air-conditioning operation control unit 11 controls the air-conditioning operation unit 23 so that the room temperature becomes a set temperature during the cooling operation and the heating operation. In the automatic mode and the wind setting mode, the set temperature is kept constant. On the other hand, in the energy-saving operation mode, the set temperature is gradually relaxed and changed toward the outside air temperature. Hereinafter, a mode in which the set temperature is maintained constant, such as the automatic mode and the wind power setting mode, is referred to as a normal operation mode (normal operation).

The air-conditioning operation control unit 11 normally operates in the normal operation mode in the cooling operation and the heating operation, and shifts to the energy-saving operation mode (energy-saving operation) when the energy-saving operation mode is set. The energy-saving operation mode can be set by using the remote controller 26, the input receiving unit of the main body of the air conditioner 1 (usually the indoor unit), the communication terminal device 50 associated with the air conditioner 1, and the like. can.

The timing of the transition from the normal operation mode to the energy-saving operation mode may be when the energy-saving operation mode is set. It may be when it is detected. Alternatively, it may be migrated by another trigger.

In the energy-saving operation mode, the time width and the temperature width when the set temperature is gradually relaxed may be stored in the storage unit 22 and may be a fixed value. Further, the user may be able to set by using the remote controller 26, the input receiving unit of the main body of the air conditioner 1, the communication terminal device 50, and the like.

The server 40 includes a server control unit 41, a communication unit 42, a storage unit 43, and the like that control the operation of each unit of the server 40. The communication unit 42 enables communication between the server 40 and the external device. The storage unit 43 stores various information / programs necessary for the operation of the server 40.

The server control unit 41 controls the operation of each unit of the server 40 according to the information / program stored in the storage unit 43, which is composed of a computer device including, for example, an arithmetic processing unit such as a CPU or a dedicated processor. A branch time calculation unit 45 is constructed in the server control unit 41.

In the present embodiment, the configuration in which the branch time calculation unit 45 is provided in the server control unit 41 is exemplified, but the branch time calculation unit 45 is the air conditioner control unit 10 of the air conditioner 1 or the communication terminal device 50. It may be provided in the terminal control unit 60 described later. In short, the branch time calculation unit 45 may be included in the air conditioning system 30.

In the branch time calculation unit 45, when the air conditioner 1 is performing the cooling operation or the heating operation, the power consumption A when the operation is temporarily stopped and then restarted, and the power consumption B when the operation is continued are determined. Calculate the branch time corresponding to the same stop time. The power consumption A when the operation of the air conditioner 1 is temporarily stopped and then restarted is the power consumption for restarting the operation after stopping and making it the same as the room temperature before the stop. As described above, since the server 40 receives the operation data, the outside temperature, the room temperature, etc. of the air conditioner 1 from the air conditioner 1, the power consumption A and the power consumption B can be calculated.

FIG. 3 is a schematic diagram illustrating a branch time in which the power consumption A when the operation is temporarily stopped and then restarted and the power consumption B when the operation is continued are the same. In FIG. 3, the horizontal axis represents time and the vertical axis represents the power consumption of the air conditioner 1.

As shown in FIG. 3, when the stop time is short (the elapsed time from stopping the operation is short), the power consumption is smaller when the operation is continued than when the operation is stopped. When the operation is continued, the operation is performed in a stable state where the room temperature has reached the set temperature. In the stable state, the so-called thermo-off operation in which the compressor or the like is stopped is performed, and the power consumption is extremely small.

On the other hand, once the operation is stopped, when the operation is restarted (at the start of the operation), the operation with extremely large power consumption such that the compressor is fully operated is performed in order to bring the room temperature to the set temperature. Therefore, even if the downtime is short, the power consumption is high. Therefore, when the time for stopping the air conditioner 1 is short, the power consumption can be suppressed by selecting the continuation of the operation.

However, even if the operation is in a stable state, the total power consumption accumulated increases as the operation time becomes longer. Therefore, as shown in FIG. 3, the power consumption when restarting after stopping is exceeded at some time, and after that, the power consumption can be suppressed by selecting the operation stop.

The branch time calculation unit 45 reads out the start-up electric energy and the steady-state electric energy stored in the storage unit 43 at the start of operation, temporarily stops the operation, and then restarts and stops. The branching time at which the power consumption A for making the room temperature the same as the previous room temperature and the power consumption B when the operation is continued is calculated is calculated. In FIG. 3, the time Tm3 is the branch time.

It goes without saying that the power consumptions A and B change depending on the performance of the air conditioner 1, but also change depending on the performance of the room, the outside air temperature, and the like. Room performance is the temperature maintenance performance of the room. In the case of a room with low temperature maintenance performance, since the room temperature approaches the outside air temperature in a short time, the slope of the graph showing the power consumption when the operation is continued becomes large, and the branching time becomes short. The slope of the graph showing the amount of power consumption when the operation is stopped is also large, but it is smaller than the slope increase of the graph when the operation is continued. Even when the outside temperature is high, the branching time is short because the room temperature approaches the outside temperature in a short time.

Further, the power consumption B when the operation is continued is different between the normal operation mode and the energy saving operation mode. The method of calculating the power consumption B in the energy-saving operation mode will be described in detail in the fourth embodiment. Since the method for calculating the power consumption B in the normal operation mode can be calculated by using the known methods described in Patent Documents 2 and 3 described above, no further description will be given.

Returning to FIG. 2, it is preferable that the branch time calculation unit 45 always calculates the branch time while the air conditioner 1 is performing the cooling operation or the heating operation. This is because, as described above, the branching time changes from moment to moment depending on the outside air temperature and the like. The server control unit 41 transmits the calculated branch time to the communication terminal device 50. Considering that the branch time changes from moment to moment, it is preferable to transmit the branch time in real time.

The communication terminal device 50 includes a terminal control unit (input control unit, communication control unit) 60, a communication unit 51, a storage unit 52, a display unit 53, an input unit 54, and a voice output unit that control the operation of each unit of the communication terminal device 50. It includes 55, an oscillating unit 56, and the like. The communication unit 51 enables communication between the communication terminal device 50 and the external device. The storage unit 52 stores various information / programs necessary for the operation of the communication terminal device 50.

The display unit 53, the voice output unit 55, and the oscillation unit 56 are notification units for notifying the user of information. The display unit 53 displays characters, images, and the like, the voice output unit 55 uses sound and voice, and the oscillation unit 56 vibrates the communication terminal device 50 to notify the content of information or the existence of information.

The input unit 54 receives an instruction input from the user, and is an input by a key or a button, an input by a touch operation using the display unit 53, a voice input by a microphone, and the like.

The terminal control unit 60 is composed of a computer device composed of, for example, an arithmetic processing unit such as a CPU and a dedicated processor, and controls the operation of each unit of the communication terminal device 50 according to information / programs stored in the storage unit 52. The terminal control unit 60 is constructed with an air conditioner operation unit 61, a position information acquisition unit 63, and a notification control unit 62.

The air conditioner operation unit 61 accepts the operation of the air conditioner 1. The air conditioner operation unit 61 is constructed by a dedicated application downloaded to the communication terminal device 50 or the like. The air conditioner operation unit 61 displays an operation screen for operating the air conditioner 1 on the display unit 53, and receives an instruction input using the operation screen. The instruction content received by the air conditioner operation unit 61 is transmitted to the air conditioner 1 via the server 40, and the air conditioner 1 executes the instructed operation. When the communication terminal device 50 is connected to the air conditioner 1 without going through the server 40, it can be transmitted to the air conditioner 1 without going through the server 40. Further, the operation screen may include a request button or the like for requesting the display of the branch time from the user.

The position information acquisition unit 63 acquires the position information of the communication terminal device 50. The position information acquisition unit 63 is realized by, for example, a GPS function.

The notification control unit 62 controls the notification unit described above to actively notify the branch time received from the server 40 at a preset timing. In the present embodiment, the notification timing is set when the communication terminal device 50 is separated from the installation position of the air conditioner 1 by a set distance or more. When the notification control unit 62 detects that the communication terminal device 50 is separated from the installation position of the air conditioner 1 by a set distance or more from the position information acquired by the position information acquisition unit 63, the notification control unit 62 actively notifies the branch time.

To actively notify the branch time is, for example, to display it on the screen of the display unit 53 by using the notification function. Displaying using the notification function means notifying as notification. As a result, a state in which the dedicated application for operating the air conditioner 1 is not started (a state in which the operation screen is not open), a state in which the screen is locked, or an image of another application is displayed on the screen. Even when it is displayed, the branch time can be notified to the user.

In this case, more preferably, the voice output unit 55, the oscillation unit 56, or both of them are used to display the branch time in a notification format together with the ringtone and / or vibration. When the notification unit is provided with a light emitting unit such as an LED, the light emitting unit may be used together.

Further, when the notification timing is reached while the operation screen of the air conditioner 1 is displayed, the notification control unit 62 displays the branch time in a pop-up on the operation screen so that the branch time is conspicuous. indicate.

FIG. 4 is a diagram for explaining the timing at which the branch time in the air conditioning system 30 is notified. As shown in FIG. 4, the position (setting point) of the user's house 31 of the air conditioner 1 is registered in the notification control unit 62 of the communication terminal device 50 as the installation position of the air conditioner 1. The notification control unit 62 constantly determines whether or not the position information of the communication terminal device 50 acquired by the position information acquisition unit 63 is separated by a set distance r or more.

When it is determined that the position of the communication terminal device 50 is separated from the set point by the set distance r or more, the notification control unit 62 notifies the branch time with the stop time as 0 hour. That is, if the time when the position of the communication terminal device 50 is separated from the set point by the set distance r or more is, for example, "10:10 AM", the operation of the air conditioner 1 is stopped at this "10:10 AM". The branch time, which is the stop time at which the power consumption A and the power consumption B when the operation is continued is the same, is calculated. The set distance r may be a fixed value set in advance, but it is preferable that the set distance r has a configuration that can be appropriately set by the user of the air conditioner 1.

Both (a) and (b) of FIG. 5 are diagrams showing an example of a screen for notifying the branch time displayed on the display unit 53 of the communication terminal device 50. In the example shown in (a) of FIG. 5, the branch time is effectively used, such as "If you go out for up to XX minutes, it seems that the electricity bill will be better if you leave the energy-saving operation on." A message 70 prompting for power saving is displayed. "○○ minutes" is the branch time.

As a result, for example, even if the air conditioner 1 is scheduled to return immediately and goes out without stopping, and then forgets that the air conditioner 1 is in operation and tries to move beyond the set distance r, the branch time By being notified, it is possible to remember that the vehicle is in operation, and at this point, it is possible to review whether to continue or stop the operation again. Further, when the energy-saving operation mode is not set, the branch time in the energy-saving operation mode is notified, so that the transition to the energy-saving operation mode can be instructed at this point.

When the message 70 is displayed by the notification function, by touching (tapping) the display portion of the message 70, the dedicated application is activated and the operation screen of the air conditioner 1 is displayed. This makes it possible to stop the air conditioner 1 or instruct the transition to the energy-saving operation mode using the operation screen. If the communication terminal device 50 is locked, it is necessary to release the lock.

In the example shown in FIG. 5B, a stop button 71 for receiving an instruction to stop the operation of the air conditioner 1 is displayed together with the message 70. By touching the stop button 71, the air conditioner 1 can be stopped without starting the dedicated application. If the communication terminal device 50 is locked, it is necessary to release the lock.

Further, even when the branch time is popped up on the operation screen while the operation screen of the air conditioner 1 is already displayed, the stop button 71 is accompanied by the message 70 as in the example shown in FIG. 5B. By displaying, the air conditioner 1 can be stopped without taking steps such as turning off the pop-up display and returning to the operation screen.

As described above, according to the above configuration, when the communication terminal device 50 of the user of the air conditioner 1 is separated from the installation position of the air conditioner 1 by a set distance r or more, the branch time information is transmitted to the communication terminal device 50. Be actively notified. Therefore, the user can receive this notification and review whether to continue or stop the operation based on the branch time from this point in time. As a result, the notification of the branch time can be effectively used to save energy.

[Second Embodiment]
A second embodiment of the present invention will be described below. For convenience of explanation, the same reference numerals are given to the members having the same functions as the members described in the above-described embodiment, and the description thereof will not be repeated.

In the communication terminal device 50 of the first embodiment, the timing for notifying the branch time is set when the communication terminal device 50 is separated from the installation position of the air conditioner 1 by a set distance r or more. On the other hand, in the present embodiment, the timing for notifying the branch time is set immediately before the time when the operation of the air conditioner 1 is scheduled to be stopped.

The notification control unit 62A, which will be described later, notifies the branch time immediately before the scheduled time when the operation of the air conditioner 1 estimated based on the operation data of the air conditioner 1 is to be stopped. Since the method for notifying the branch time and the like are the same as those in the first embodiment, here, the time when the operation of the air conditioner 1 is scheduled to be stopped is estimated based on the operation data of the air conditioner 1. The method will be explained.

FIG. 6 is a block diagram showing a configuration of an air conditioning system 30A including the communication terminal device 50A according to the present embodiment. As shown in FIG. 6, the air conditioning system 30A includes a server 40A instead of the server 40, and a communication terminal device 50A instead of the communication terminal device 50. The server 40A includes a scheduled stop time acquisition unit 46 in the server control unit 41A. The communication terminal device 50A includes a notification control unit 62A in place of the notification control unit 62 in the terminal control unit 60A. The terminal control unit 60A may not include the position information acquisition unit 63. These points are different from the first embodiment.

In this embodiment, the configuration in which the scheduled stop time acquisition unit 46 is provided in the server control unit 41A is exemplified, but the scheduled stop time acquisition unit 46 is the air conditioner control unit 10 of the air conditioner 1 or the communication terminal. It may be provided in the terminal control unit 60A of the device 50A. In short, the scheduled stop time acquisition unit 46 may be included in the air conditioning system 30.

The scheduled stop time acquisition unit 46 derives and acquires the scheduled stop time that can be estimated to be stopped from the operation data of the air conditioning operation unit 23 received from the air conditioner 1. The targets of the operation (air conditioning operation) for deriving the scheduled stop time are the cooling operation and the heating operation. The server control unit 41A transmits the acquired scheduled stop time to the communication terminal device 50A, and the communication terminal device 50A stores this in the storage unit 52.

As described above, the operation data includes the time when the air conditioning operation unit 23 started operation, the time when the operation was stopped, the operation type, the operation mode, the set temperature, and the changed time when the set temperature was changed. It contains various information such as the later set temperature. Therefore, the scheduled stop time can be obtained by finding the pattern of the time (time) at which the cooling operation and the heating operation are stopped from such operation data by learning.

For example, as a general usage of an air conditioner, when waking up in the morning, the air conditioning operation of heating in winter and cooling in summer is started, and the operation is stopped when going out to work or school. There is such a usage. For example, an operation pattern as shown in FIG. 7 can be obtained from one week's operation data of a user of such usage. FIG. 7 is a diagram showing an example of an operation pattern of the air conditioner.

In the example of FIG. 7, from Monday to Friday, the operation is started at about 6:15 am and stopped at about 8:45 am. Saturday and Sunday deviate from this pattern. When the operation pattern as shown in FIG. 7 is confirmed in other weeks, the scheduled stop time acquisition unit 46 determines 8:45 am as the "scheduled stop time" on weekdays and acquires it.

Driving patterns are related to life patterns, and life patterns are often different on holidays and non-holidays. Therefore, it is preferable to learn and acquire the scheduled stop time for each day of the week or separately for weekdays and holidays.

The notification control unit 62A of the communication terminal device 50A reads out the scheduled stop time from the storage unit 52, and notifies the branch time immediately before the scheduled stop time. Immediately before the scheduled stop time is a short time such as 3 minutes or 5 minutes before the scheduled stop time. This time may also be a fixed value set in advance, but it is preferable that the time can be appropriately set by the user of the air conditioner 1.

As described above, according to the above configuration, the information on the branch time is actively notified to the communication terminal device 50A immediately before the user of the air conditioner 1 tries to stop the air conditioner 1. Therefore, in response to this notification, the user can select whether to continue or stop the operation based on the branch time. As a result, the notification of the branch time can be effectively used to save energy.

[Fourth Embodiment]
A fourth embodiment of the present invention will be described below. For convenience of explanation, the same reference numerals are given to the members having the same functions as the members described in the above-described embodiment, and the description thereof will not be repeated.

In this embodiment, a method of calculating the power consumption B when the operation is continued in the energy-saving operation mode will be described.

The branch time calculation unit 45 has a function of learning the amount of electric power of the air conditioner 1 by dividing it into situations. Specifically, the following (1) to (4) are acquired by learning.
(1) The amount of electric power per hour (Wh) in a stable state for each difference between the outside air temperature and the room temperature.
(2) The amount of electric power (Wh) per hour during energy-saving operation in which the set temperature is gradually relaxed from the stable state for each difference between the outside air temperature and the room temperature.
(3) The amount of electric power (Wh) required to reach the set temperature when the operation is temporarily stopped and then restarted for each difference between the outside air temperature and the room temperature and for each difference between the room temperature and the set temperature.
(4) To reach the set temperature before the room temperature is relaxed from the stable state where the energy-saving operation is canceled and the set temperature is relaxed for each difference between the outside air temperature and the room temperature and for each difference between the room temperature and the set temperature. The amount of power required for (Wh).

FIG. 8 is an example of a table of electric energy (Wh) of the air conditioner 1 per hour during energy-saving operation for each difference between the outside temperature and the room temperature in (2) above, which was learned by the branch time calculation unit 45. It is a figure which shows. In the example of FIG. 8, the difference between the outside air temperature and the room temperature is 1 ° C. or higher and lower than 3 ° C., 3 ° C. or higher and lower than 6 ° C., 6 ° C. or higher and lower than 9 ° C., 9 ° C. or higher and lower than 12 ° C., and 12 ° C. or higher and lower than 15 ° C. It is divided into 5 stages, and the amount of electric power per hour in each stage is acquired by learning. For example, when the difference between the outside air temperature and the room temperature is 7 ° C., 450 Wh is used as the amount of electric power per hour.

FIG. 9 shows the original set temperature of the room temperature when the energy-saving operation is canceled for each difference between the outside air temperature and the room temperature and for each difference between the room temperature and the set temperature created by the branch time calculation unit 45. It is a figure which shows an example of the table of the electric energy (Wh) of the air conditioner 1 required to reach. In the energy-saving operation, the operation at the time of starting, which consumes an extremely large amount of power as in the case where the operation is temporarily stopped and then restarted, is not performed. Therefore, the operation is created separately from FIG. 10 described later. In the example of FIG. 9, the difference between the outside air temperature and the room temperature is 1 ° C. or higher and lower than 3 ° C., 3 ° C. or higher and lower than 6 ° C., 6 ° C. or higher and lower than 9 ° C., 9 ° C. or higher and lower than 12 ° C., and 12 ° C. or higher and lower than 15 ° C. It is divided into 5 stages, and the difference between the room temperature and the set temperature is created in 1 ° C increments. For example, when the difference between the outside air temperature and the room temperature is 7 ° C. and the difference between the room temperature and the set temperature is 4 ° C. when shifting from the energy-saving operation to the normal operation, 900 Wh is used as the amount of electric power required for returning.

FIG. 10 shows the room temperature when the operation is temporarily stopped and then restarted for each difference between the outside air temperature and the room temperature and for each difference between the room temperature and the set temperature created by the branch time calculation unit 45. It is a figure which shows an example of the table of the electric energy (Wh) of the air conditioner 1 required to reach a set temperature. Similar to FIG. 9, in FIG. 10, the difference between the outside air temperature and the room temperature is 1 ° C. or higher and lower than 3 ° C., 3 ° C. or higher and lower than 6 ° C., 6 ° C. or higher and lower than 9 ° C., 9 ° C. or higher and lower than 12 ° C., 12 ° C. or higher. It is divided into 5 stages of less than 15 ° C, and the difference between the room temperature and the set temperature is created in 1 ° C increments. For example, when the difference between the outside air temperature and the room temperature is 7 ° C. and the difference between the room temperature and the set temperature is 4 ° C. when the operation is temporarily stopped and then restarted, 1100 Wh is used as the amount of electric power required for returning.

Further, the branch time calculation unit 45 creates a table of the room temperature change width when the operation of the room in which the air conditioner 1 is installed is stopped for each difference between the outside air temperature and the room temperature and for each hour by learning. do. It should be noted that the table having such a temperature range is different between the cooling operation and the heating operation. Further, even if the performance of the air conditioner 1 is the same, it differs depending on the performance of the room in which the air conditioner 1 is installed. The branch time calculation unit 45 has a function of determining the performance of the room. The function will be described in detail in the fifth embodiment.

FIG. 11 is a table of room temperature change width when the operation of the room in which the air conditioner 1 is installed is stopped for each difference between the outside air temperature and the room temperature and for each time, which is created by the branch time calculation unit 45. It is a figure which shows an example. As shown in FIG. 11, the range of change in room temperature increases as the difference between the outside air temperature and the room temperature increases and the elapsed time increases.

The content learned by the branch time calculation unit 45 as described above is stored in the storage unit 43. In this embodiment, since it is assumed that the branch time calculation unit 45 is provided in the server 40, a table required by the learning function is created. However, when the branch time calculation unit 45 is provided in the air conditioner 1 or the communication terminal device 50 and does not have a learning function, even if the configuration is such that a table corresponding to the performance of the air conditioner 1 is provided in advance. good. In that case, since the table of the room temperature change width shown in FIG. 11 changes depending on the performance of the room, a plurality of tables may be provided in advance and the user may select the table according to the performance of the room.

Next, the procedure for calculating the branch time by the branch time calculation unit 45 will be described. The branch time calculation unit 45 reads out the content learned from the storage unit 43. The branch time calculation unit 45 estimates the amount of electric power for each elapsed time, assuming that the energy-saving operation is started from the current room temperature of the room in which the air conditioner 1 is installed (first estimation).

In the first estimation, the table of FIG. 8 is used. For example, when the set temperature is relaxed by 1 ° C. in 15-minute increments, the electric energy is estimated at each stage in which the set temperature is changed by 1 ° C. every 15 minutes. The electric energy for 15 minutes in the first stage in which the set temperature is relaxed by 1 ° C. is calculated as 450/4 = 112.5Wh when the difference between the outside air temperature and the room temperature is 7 ° C. The electric energy for the following 15 minutes in the second step is calculated as 112.5 Wh if the difference between the outside air temperature and the room temperature is 7 ° C, and 300/4 = 75 Wh if the difference is less than 6 ° C.

Next, the branch time calculation unit 45 estimates the amount of electric power until the room temperature reaches the original set temperature when the energy-saving operation is canceled (second estimation). In the second estimation, the table of FIG. 9 is used. For example, when the set temperature is relaxed by 1 ° C in 15-minute increments, the amount of power required to return to the original set temperature at each stage where the set temperature is changed by 1 ° C is estimated every 15 minutes. .. The amount of power required to return the room temperature to 1 ° C in the first 15 minutes after loosening the set temperature by 1 ° C is 600 Wh when the difference between the outside air temperature and the room temperature is 7 ° C, and the difference between the outside air temperature and the room temperature. When is 5 ° C., it becomes 500 Wh. In addition, the amount of electric power required to cancel the energy-saving operation and return the room temperature to 4 ° C 60 minutes after the fourth stage in which the set temperature is relaxed by 4 ° C is 900 Wh when the difference between the outside air temperature and the room temperature is 7 ° C. When the difference between the outside air temperature and the room temperature is 5 ° C., it is 800 Wh.

The branch time calculation unit 45 saves energy by adding the amount of power required for returning the room temperature obtained in the second estimation to the original set temperature to the amount of power during the energy-saving operation obtained in the first estimation. Generate an estimated electric energy table including the period from operation to its release. FIG. 12 is a diagram showing an example of an estimated electric energy amount (power consumption B) table for each time at a certain temperature including the period from energy saving operation to its release, which is created by the branch time calculation unit 45.

Next, the branch time calculation unit 45 estimates the power consumption when the operation of the air conditioner 1 is temporarily stopped and then restarted. The power consumption when restarting after stopping may be calculated first. The branch time calculation unit 45 estimates the room temperature at the time of restarting the operation for each elapsed time using the table of the room temperature change width in FIG. 11, and the amount of electric power required to reach the room temperature from the estimated room temperature to the set temperature. Is calculated using the table of FIG.

The branch time calculation unit 45 generates an estimated electric energy table required to return the estimated room temperature calculated using the table of FIG. 10 to the original set temperature. FIG. 13 is a diagram showing an example of an estimated electric energy amount (power consumption A) table for each time when the operation is temporarily stopped and then restarted, which is created by the branch time calculation unit 45.

The branch time calculation unit 45 creates a graph as shown in FIG. 3 described above based on the data of the estimated electric energy table shown in FIGS. 12 and 13 to obtain the branch time.

[Fifth Embodiment]
A fifth embodiment of the present invention will be described below. For convenience of explanation, the same reference numerals are given to the members having the same functions as the members described in the above-described embodiment, and the description thereof will not be repeated.

Here, a method of determining the room performance by the branch time calculation unit 45 will be described with reference to FIGS. 14 to 16. 14 (a) and 16 (b) are diagrams for explaining a method for determining room performance.

(Determination method 1): As shown in FIG. 14A, when the heating operation is stopped, the room temperature decreases over time (low speed) in the room (high performance) A having high temperature maintenance performance. On the other hand, in the room C with low temperature maintenance performance (low performance), the room temperature drops in a short time (high speed). In room B (medium performance) where the temperature maintenance performance is medium, the speed decreases at the speeds of room A and room C. Although not shown, the same applies when the cooling operation is stopped, and the temperature changes in the direction of increase, but the speed of the temperature change is slow in the room (high performance) A where the temperature maintenance performance is high, and the temperature is maintained. It becomes faster in a room with low performance (low performance) C.

Therefore, the performance of the room can be determined from the room temperature (average) after a predetermined time when the operation is stopped. As shown in FIG. 14 (b), if the average room temperature drop temperature T after t hours when the heating operation is stopped is within T1, the performance is high, and if it is larger than T1 ° C but below T2 ° C, the performance is high, T2. If it is higher than ℃, it is judged that the performance is low. Here, T1 <T2. Further, T1 and T2, which are threshold values for such determination, are set by the difference between the outside air temperature and the room temperature. In the example of FIG. 14B, the room A having an average room lowering temperature T of T1 or less has high performance, the room B having a temperature larger than T1 ° C. but lower than T2 ° C. is in performance, and the room C having a temperature lower than T2 ° C. has performance. It is judged to be low.

(Determination method 2): As shown in FIG. 15A, when the heating operation is started, the room temperature reaches the set temperature in a short time and stabilizes in the room (high performance) A having high temperature maintenance performance. do. On the other hand, in the room C with low temperature maintenance performance (low performance) C, the room temperature reaches the set temperature and stabilizes over time. In room B (during performance) where the temperature maintenance performance is medium, the temperature is stabilized between room A and room C over time. Although not shown, the same applies when the cooling operation is started, and the temperature changes in the direction of decrease, but the time until stabilization is short in the room (high performance) A where the temperature maintenance performance is high. Room with low temperature maintenance performance (low performance) C becomes longer.

Therefore, the performance of the room can be determined from the time (average) required for the room temperature to stabilize at the start of operation. As shown in FIG. 15B, if the average time required to stabilize the room temperature after the start of the heating operation is within M1, the performance is high, and if it is larger than M1 but M2 or less, the performance is higher than M2. If it is large, it is judged that the performance is low. Here, M1 <M2. Further, M1 and M2, which are threshold values for such determination, are set by the difference between the outside air temperature and the room temperature. In the example of FIG. 9B, it is determined that the room A having an average required time M of M1 or less has high performance, the room B larger than M1 but M2 or less is in performance, and the room C larger than M2 has low performance. To.

(Determination method 3): As shown in FIG. 16A, in the room (high performance) A having high temperature maintenance performance after the start of heating operation, the average operating capacity (watt) when the room temperature is stable is small. On the other hand, in the room (low performance) C where the temperature maintenance performance is low, the average operating capacity when the room temperature is stable becomes large. In the room (medium performance) B where the temperature maintenance performance is medium, the average operating capacity between the room A and the room C is obtained. Although not shown, the same applies when the cooling operation is started, and the temperature changes in the direction of decrease. However, the average operating capacity when the room temperature is stable is in the room (high performance) A where the temperature maintenance performance is high. It is high in a room (low performance) C, which is low and has low temperature maintenance performance.

Therefore, the performance of the room can be determined from the average operating capacity when the room temperature is stable. As shown in FIG. 16B, if the average operating capacity W is within W1, it is determined to be high performance, if it is larger than W1 but smaller than W2, it is judged to be in performance, and if it is larger than W2, it is judged to be low performance. Here, W1 <W2. Further, W1 and W2, which are threshold values for such determination, are set by the difference between the outside air temperature and the room temperature. In the example of FIG. 16B, it is determined that the room A having an average operating capacity W within W1 has high performance, the room B larger than W1 but less than W2 is in performance, and the room C larger than W2 has low performance. The room.
