[0020] The terminal device 5 is a smart device such as a smartphone, tablet terminal, or PC owned by the user. The terminal device 5 displays the air conditioning or ventilation status of the room R using the operating information of the air conditioning device 1 and the ventilation device 2 and environmental information received from the remote controller 4.

[0021] 2 is a control block diagram of the display system 100 pertaining to embodiment 1. The air conditioning apparatus 1 is connected to a remote controller 4 so as to be able to communicate by wire or wirelessly. The air conditioning apparatus 1 receives control signals from the remote controller 4 and operates based on the received control signals. The air conditioning apparatus 1 also periodically (for example, every 10 minutes) transmits operating information of its own device to the remote controller 4.

[0022] The ventilation device 2 is connected to the remote controller 4 so as to be able to communicate by wire or wirelessly. The ventilation device 2 receives control signals from the remote controller 4 and operates based on the received control signals. The ventilation device 2 also periodically (e.g., every 10 minutes) transmits its own operating information to the remote controller 4.

[0023] The information acquisition device 3 is connected to the remote controller 4 so as to be able to communicate by wire or wirelessly. The information acquisition device 3 periodically (for example, every 10 minutes) acquires environmental information of the room R and transmits the acquired environmental information to the remote controller 4.

[0024] The remote controller 4 is connected to the air conditioning device 1, the ventilation device 2, the information acquisition device 3, and the terminal device 5 so as to be able to communicate via wired or wireless communication. As shown in Fig. 2 , the remote controller 4 includes an operation device 41, a display device 42, a communication device 43, a control device 44, and a storage device 45.

[0025] The operation device 41 is made up of, for example, a plurality of operation buttons or a touch panel, and is operated by the user when inputting instructions to the air conditioner 1 and the ventilator 2. The display device 42 is, for example, a liquid crystal display or an organic EL display, and displays settings and operating information, etc. of the air conditioner 1 and the ventilator 2. The communication device 43 is a communication interface that performs wired communication or wireless communication such as a wireless PAN or wireless LAN with the air conditioner 1, the ventilator 2, the information acquisition device 3, and the terminal device 5.

[0026] The control device 44 is composed of a processor such as a CPU or GPU, a processing circuit such as an ASIC or FPGA, or both. The control device 44 transmits control signals to the air conditioning device 1 and the ventilator 2 based on instructions from the user input via the operation device 41. The control device 44 also stores the operating information received from the air conditioning device 1 and the ventilator 2 and the environmental information received from the information acquisition device 3 in the storage device 45 on an hourly basis. Furthermore, the control device 44 transmits past operating information and environmental information stored in the storage device 45 to the terminal device 5 in response to a request from the terminal device 5.

[0027] The storage device 45 is, for example, a non-volatile semiconductor memory such as a ROM or a flash memory, an HDD, an SSD, etc. The storage device 45 stores the operating information received from the air conditioning device 1 and the ventilator 2 and the environmental information received from the information acquisition device 3.

[0028] Fig. 3 shows an example of operating information and environmental information stored in the remote controller 4 according to embodiment 1. As shown in Fig. 3, the storage device 45 of the remote controller 4 stores time-series data of operating information received from the air conditioning device 1 and the ventilator 2, and time-series data of environmental information received from the information acquisition device 3. In the example of Fig. 3, the operating mode and set temperature of the air conditioning device 1 and the set air volume of the ventilator 2 are stored as operating information, and the indoor temperature, indoor humidity, CO ２ 3, only a portion of the data is shown, but the storage device 45 stores time-series data of the operating information of the air conditioning device 1 and the ventilator 2 and environmental information for, for example, the past 13 months.

[0029] 2 , the terminal device 5 is wirelessly connected to the remote controller 4. The terminal device 5 includes an operation device 51, a display device 52, a communication device 53, a control device 54, and a storage device 55.

[0030] The operation device 51 includes, for example, a touch panel and operation buttons, and is operated when the user inputs instructions regarding the display of the status of the room R. The display device 52 is, for example, a liquid crystal display or an organic EL display, and displays the status of the room R. The communication device 53 is a communication interface that performs wireless communication with the remote controller 4 via a wireless PAN or a wireless LAN.

[0031] The control device 54 is composed of a processor such as a CPU or GPU, a processing circuit such as an ASIC or FPGA, or both. The control device 54 performs status display processing for displaying the status of the indoor R by executing an application program stored in the storage device 55. In the status display processing, the control device 54 receives from the remote controller 4 the operating information and environmental information of the air conditioning device 1 and the ventilator 2 for the past day specified by the user, generates a status display screen 7 ( FIG. 6 ) showing the status of the indoor R for that day, and displays it on the display device 52.

[0032] The storage device 55 is, for example, a non-volatile semiconductor memory such as a ROM or a flash memory, a volatile semiconductor memory such as a RAM, an HDD, an SSD, etc. The storage device 55 stores application programs executed by the control device 54 and various data such as screen data used in executing the application programs.

[0033] 4 is a diagram showing the flow of operation of the display system 100 according to embodiment 1. As shown in Fig. 4, first, operation information from the air conditioning device 1 and the ventilator 2 and environmental information from the information acquisition device 3 are periodically transmitted to the remote controller 4 (S1). The remote controller 4 stores the received operation information and environmental information in the storage device 45 (S2).

[0034] Here, the air conditioning apparatus 1, the ventilator 2, and the information acquisition device 3 transmit information synchronously. This allows the remote controller 4 to acquire operating information and environmental information for the same time. Furthermore, the interval at which the air conditioning apparatus 1, the ventilator 2, and the information acquisition device 3 transmit information is not limited to the 10-minute interval exemplified above. Furthermore, although the air conditioning apparatus 1, the ventilator 2, and the information acquisition device 3 transmit information periodically, this is not limitative. For example, during times of the day when there is no need to check the status of the indoor R, such as at night, the transmission of information by the air conditioning apparatus 1, the ventilator 2, and the information acquisition device 3 may be stopped, or the interval at which information is transmitted may be longer than during the day.

[0035] In response to a user instruction, the control device 54 of the terminal device 5 starts an application program related to processing for displaying the status of the room R (S3). Then, the control device 54 displays a date selection screen 6 on the display device 52 (S4). Fig. 5 shows an example of the date selection screen 6 displayed on the terminal device 5 according to the first embodiment. The date selection screen 6 is a screen for the user to select a past day on which they want to check the status of the room R.

[0036] As shown in Fig. 5, the date selection screen 6 has a year / month selection section 61, a date selection section 62, and a confirm button 63. The user selects the date by selecting the year / month and date in the year / month selection section 61 and the date selection section 62 and pressing the confirm button 63. The date selection screen 6 is not limited to the example in Fig. 5, and may be any screen that allows the user to select the year / month and date.

[0037] 4 , when a date is selected on the date selection screen 6 and the decision button 63 is pressed, the control device 54 accepts the date selection (S5). Then, it requests the remote controller 4 for driving information and environmental information for the selected date (S6). The control device 44 of the remote controller 4 extracts time-series data for the requested date from the driving information and environmental information stored in the storage device 45 and transmits it to the terminal device 5 (S7). The control device 54 of the terminal device 5 generates the status display screen 7 based on the time-series data of the driving information and environmental information received from the remote controller 4 and displays it on the display device 52 (S8).

[0038] Fig. 6 is an example of a status display screen 7 displayed on the terminal device 5 according to Embodiment 1. As shown in Fig. 6, the status display screen 7 includes a status display section 71 that includes operating information about the air conditioning device 1 and the ventilator 2 and environmental information, and selection buttons 72 for selecting items to be displayed on the status display section 71.

[0039] The status display unit 71 includes time series data of operating information for the air conditioning device 1 and the ventilator 2, and time series data of environmental information, for the day selected on the date selection screen 6. Furthermore, the status display unit 71 displays the time series data of operating information and the time series data of environmental information on the same time axis. Furthermore, in the example of Fig. 6, the time series data of operating information and the time series data of environmental information are displayed overlapping each other.

[0040] In FIG. 6, the horizontal axis represents time, and the vertical axis represents indoor temperature and CO ２ In addition, in Figure 6, the indoor temperature and CO ２ To distinguish it from the concentration, the indoor temperature is shown with a dashed line, and the CO ２Although the concentrations are shown as solid lines, they may also be shown in different colors or thicknesses.

[0041] In addition, in FIG. 6 , the operating information includes an icon and set temperature indicating the operating mode of the air conditioning apparatus 1, an icon and set airflow rate indicating the operation of the ventilation apparatus 2, and vertical lines corresponding to each piece of operating information, which are displayed on the time axis (horizontal axis). To distinguish between the operating information of the air conditioning apparatus 1 and the operating information of the ventilation apparatus 2, the operating information of the air conditioning apparatus 1 is displayed using a dashed line and the operating information of the ventilation apparatus 2 is displayed using a dashed line. However, these may be displayed in different colors or thicknesses. Furthermore, the icons indicating the operating information may be displayed in different colors depending on the operating status. For example, if the air conditioning apparatus 1 is operating in cooling mode, the icon may be blue, and if the air conditioning apparatus 1 is operating in heating mode, the icon may be red. Furthermore, the color may be further varied depending on the details of the operating status, such as if the air conditioning apparatus 1 is operating in cooling mode and the set temperature is 20°C, the icon may be dark blue, and if the air conditioning apparatus 1 is operating in cooling mode and the set temperature is 28°C, the icon may be light blue. The display on the status display unit 71 in Figure 6 shows that the air conditioning device 1 started cooling operation at 12:00 with a set temperature of 28°C, and that the set temperature was changed to 27°C at 14:00. It also shows that the ventilation device 2 started operation at around 12:30 with a set air volume of "high," and that the set air volume was changed to "low" at 15:50.

[0042] Although FIG. 6 only displays driving information and environmental information from 8:00 to 20:00, by scrolling the status display section 71, driving information and environmental information for other times can be displayed.

[0043] The selection buttons 72 are provided corresponding to the items displayed in the status display section 71. In the example of FIG. 6, the selection buttons 72 are "Set temperature" of the air conditioning device 1, "Set air volume" of the ventilation device 2, "Room temperature" and "CO ２ The items are "color density" and "color density," and selection buttons 72 corresponding to these items are provided. By pressing a selection button 72, the user can switch between displaying and hiding the corresponding item.

[0044] 7 is another example of the status display screen 7 displayed on the terminal device 5 according to the first embodiment. For example, when the user operates the selection button 72 and selects not to display the "set temperature" and "set air volume," the status display section 71 displays the indoor temperature and CO 2 , which are environmental information, as shown in FIG. ２ Only the concentration is displayed.

[0045] The effects of the display system 100 of this embodiment will be described. First, conventionally, the effects of air conditioning and ventilation were confirmed by the user actually feeling whether the indoor temperature had become comfortable or not, or by the user checking whether the set temperature and the indoor temperature were the same. In this case, only the current effect was known, and it was not possible to review past effects later. Furthermore, when scheduling the operation time and set temperature of the air conditioner 1 in advance, the user had to predict and set the time while remembering how long it would take for the air conditioning effect to appear, and what time the indoor temperature would start to rise, etc. In this case, it was difficult for the user to clearly remember the past indoor R conditions, making it difficult to set a schedule to achieve a comfortable state. Regarding the ventilation device 2, ２ It is difficult for the user to feel the increase or decrease in concentration. ２ The only way to judge the effect was by looking at the change in concentration values.

[0046] As such, the effects of air conditioning and ventilation are difficult to see, making it difficult for users to confirm their effectiveness. In contrast, in this embodiment, time-series data of operating information for the air conditioning device 1 and ventilation device 2 and time-series data of environmental information such as indoor temperature are displayed on the same time axis on the terminal device 5, making the correlation between changes in operating information and changes in environmental information clear. This allows users to easily confirm the effects of air conditioning and ventilation.

[0047] For example, from the indoor temperature graph in the status display unit 71 in Figure 6 and the operating information of the air conditioner 1, the user can easily understand what the indoor temperature was before the air conditioner 1 started operating, how it changed after operation, and how much the indoor temperature changed before and after the set temperature was changed from 28°C to 27°C. ２ From the graph of the concentration and the operation information of the ventilation device 2, the CO ２ What is the concentration in ppm, how has it changed after operation, and how much CO was present before and after the set air volume of the ventilation device 2 was changed from "strong" to "weak"? ２ The user can easily grasp whether the concentration has changed, etc. Furthermore, by displaying both the operating information of the air conditioning device 1 and the operating information of the ventilation device 2 on the status display unit 71, the user can also check the effect of ventilation on the indoor temperature.

[0048] This allows the user to easily determine when to operate or stop the air conditioning device 1 and the ventilation device 2 to make the room more comfortable, or when to change the set temperature of the air conditioning device 1 or the set air volume of the ventilation device 2 to make the room more comfortable. As a result, the user can operate the remote controller 4 to advance the start time of the air conditioning device 1 or adjust the air volume of the ventilation device 2. In this way, by performing the display of this embodiment, the effects of air conditioning and ventilation can be visualized, and the user can be prompted to control the air conditioning device 1 and the ventilation device 2 to improve comfort.

[0049] Furthermore, by displaying time-series data of the operating information of the air conditioning device 1 and the ventilation device 2 and time-series data of environmental information such as the indoor temperature in an overlapping manner, it is possible to easily compare them. Furthermore, by displaying the status display screen 7 on the display device 52 of the terminal device 5, it is possible to display multiple items in different colors in an overlapping manner without being subject to screen size and memory restrictions, as compared to when displaying on the remote controller 4. This makes it easier to see the status of the room R.

[0050] Furthermore, when time-series data of operational information and time-series data of environmental information are displayed simultaneously on one screen, the increased amount of displayed information makes it difficult to see each piece of information, making it difficult to understand changes in status. In contrast, in this embodiment, the operational information of the air conditioning device 1 and the ventilator 2 is displayed as icons, making it possible to grasp the operational status at a glance. This makes the display on the status display unit 71 easier to read than when the operational information is displayed as text.

[0051] The status display screen 7 displayed on the terminal device 5 is not limited to the example shown in Fig. 6. Modified examples of the status display screen 7 will be described below.

[0052] (Modification 1) Fig. 8 is an example of a status display screen 7 according to Modification 1. In Embodiment 1, the operating information of the air conditioning apparatus 1 and the ventilation apparatus 2 is displayed using vertical lines as shown in Fig. 6 . However, as shown in Fig. 8 , the operating information of at least one of the air conditioning apparatus 1 and the ventilation apparatus 2 may be displayed using dots. In this case, when a point is selected (tapped) by the user, the operating information corresponding to the selected point is displayed using text and an icon. In the example of Fig. 8 , when the point indicated by the outline arrow is selected by the user, the operating information corresponding to the selected point (cooling: 27°C) is displayed using text and an icon. This simplifies the display of the status display unit 71, making it easier to see.

[0053] (Variation 2) Fig. 9 is an example of a status display screen 7 according to Variation 2. As shown in Fig. 9, the operating information of at least one of the air conditioning apparatus 1 and the ventilator 2 may be displayed using dots and horizontal lines. In the example of Fig. 9, the operating information of the air conditioning apparatus 1 is displayed using dots and horizontal lines. The dots indicate the start and end points of the operating information, and the horizontal lines connect the start and end points. In the example of Fig. 9, it is shown that the air conditioning apparatus 1 was operated at a set temperature of 28°C from 9:00 to 14:00, and at a set temperature of 27°C from 14:00 to 17:00. By displaying the operating status in this manner, it is possible to grasp the operating status in more detail.

[0054] The display method of the driving information is not limited to Modification 1 and Modification 2, and any display may be used as long as the correspondence between the environmental information and the driving information can be clearly seen. For example, in Modification 1, dots, characters, and icons may both be displayed. In Modification 2, characters may not be displayed, and characters may be displayed only when a dot or a horizontal line is selected by the user. Furthermore, the background of the graph of the environmental information may be displayed in a different color depending on the driving information.

[0055] (Modification 3) Fig. 10 is an example of the status display screen 7 according to Modification 3. In the first embodiment, the indoor temperature and CO ２ Although the time series data of the environmental information such as the concentration is displayed in a line graph, at least one of the environmental information may be displayed in a bar graph. ２ The time series data of the concentration is displayed as a bar graph. The values ​​of the bar graph are, for example, CO per 30 minutes. ２ This makes it easier to distinguish between the environmental information when displaying time-series data of a plurality of environmental information items on the status display unit 71, and improves visibility.

[0056] (Modification 4) Fig. 11 is an example of the status display screen 7 according to Modification 4. As shown in Fig. 11, the environmental information may be displayed in different colors depending on the value of the time-series data. For example, in the example of Fig. 11, ２ In the concentration bar graph, CO ２ Concentrations of 1000 ppm or less and concentrations of more than 1000 ppm are displayed in different colors. This allows the user to easily determine whether the environmental information is within the appropriate range, i.e., whether the indoor R condition is comfortable. The vertical axis or background of the environmental information graph on the status display unit 71 may be color-coded according to the value of the time-series data.

[0057] (Modification 5) FIG. 12 is an example of the status display screen 7 according to Modification 5. In the first embodiment, the operating information and environmental information for one day selected by the user are displayed, but the operating information and environmental information for multiple days may be displayed on the status display screen 7. In this case, multiple dates are selected on the date selection screen 6. When multiple dates are selected, the control device 54 displays the status display section 71 for each date in multiple tabs, as shown in FIG. 12. When the user selects a tab, the status display section 71 for each date is displayed. This allows the user to check the status of the indoor R on multiple days and determine whether the operation is comfortable.

[0058] (Variation 6) FIG. 13 is an example of the status display screen 7 according to Variation 6. As in Variation 5, when multiple dates are selected by the user, the driving information and environmental information for each date may be displayed overlapping each other, as shown in FIG. 13. In this case, the driving information and environmental information for each date are displayed overlapping each other so that the times of the driving information and environmental information match. Alternatively, one of multiple days may be selected so that the display for each date is different. In the example of FIG. 13, "August 24, 2022" is selected, and the driving information and environmental information for the unselected "August 31, 2022" are displayed in gray so as not to stand out.

[0059] This allows the user to easily compare the indoor R conditions on multiple different days and determine whether driving is comfortable. Furthermore, when displaying driving information and environmental information for multiple days in an overlapping manner, a selection button 72 may be provided for selecting items for each date. This allows only the necessary items for each date to be displayed, making the status display section 71 easier to read.

[0060] (Variation 7) Fig. 14 is an example of the status display screen 7 according to Variation 7. As shown in Fig. 14, a year / month selection section 61 and a date selection section 62 may be displayed on the status display screen 7. In this case, the status display screen 7 of Fig. 14 is displayed at the same time as the date selection screen 6 is displayed. Before a date is selected, the driving information and environmental information are not displayed on the status display section 71. Then, when a date is selected, the driving information and environmental information for the selected date are displayed on the status display section 71. This allows both operation and display on a single screen, improving convenience.

[0061] (Modification 8) Fig. 15 is an example of the status display screen 7 according to Modification 8. As environmental information, indoor temperature and CO ２ In addition to the concentration, the indoor humidity, which is the humidity in the room R, and the PM2.5 concentration may also be displayed. In Fig. 15, a line graph of the indoor humidity is displayed on the status display unit 71 instead of the indoor temperature. For example, when the air conditioning apparatus 1 is performing a dry operation to dehumidify the room R, the status display unit 71 can visualize the change in humidity due to the performance of the dry operation, thereby urging the user to control the air conditioning apparatus 1 to improve comfort.

[0062] 16 is an example of the status display screen 7 according to Modification 9. The environmental information related to the environment of the room R and the information acquisition device 3 that acquires the environmental information are not limited to those in the example of Embodiment 1. The environmental information includes comfort information of the room R such as temperature and humidity, CO ２ The information acquisition device 3 may be at least one of indoor R air quality information such as concentration, PM2.5 concentration, or status information such as the number of people in the room R, weather, outdoor temperature, power consumption, electricity bill, or illuminance. The information acquisition device 3 may be an infrared sensor or camera that acquires the number of people in the room or the illuminance of the room R, a communication terminal that acquires weather and outdoor temperature information from an external server that manages and stores weather information, an outdoor temperature sensor that measures the outdoor temperature, a device that acquires power consumption from the air conditioner 1 and the ventilator 2, or an information processing device that acquires power consumption from the air conditioner 1 and the ventilator 2 and calculates the electricity bill per unit time.

[0063] The status display unit 71 may display at least one of the following environmental information: the number of people in the room, the weather, the outdoor temperature, and the electricity rate. In the example of Fig. 16, time series data of the weather and the number of people in the room are displayed using icons and line graphs. From the display of Fig. 16, it is possible to see the CO ２ It is possible to check changes in concentration, changes in indoor humidity due to weather, and changes in electricity charges due to operation of the air conditioning device 1 and the ventilation device 2. This allows the user to determine a comfortable operation taking into account various situations.

[0064] In addition, the status display unit 71 does not display status information, and the user can select comfort information (temperature, humidity) or air quality information (CO ２ When a portion of the graph of the comfort information or air quality information (e.g., concentration, PM2.5 concentration) that appears to need improvement is selected (clicked) (either the time-series data of the comfort information or the air quality information), status information corresponding to the time of the selected portion may be displayed. For example, when a user clicks on the 12 o'clock portion of the graph of the indoor R temperature, the number of people occupying the room, the weather, the outdoor temperature, etc. at 12 o'clock may be displayed. Furthermore, the cause of discomfort may be estimated using a machine learning model or the like that is trained to output the cause of discomfort using on-site information including the number of people occupying the room R, the weather, and the outdoor temperature, and operation information, among the status information. When a portion of the graph of the comfort information or the air quality information that appears to need improvement is selected by the user, the estimated cause of discomfort may be displayed on the status display screen 7. Examples of causes of discomfort include a higher number of people than usual, a higher outdoor temperature than usual resulting in poor air conditioning efficiency, or a malfunction of the air conditioning device 1 or the ventilation device 2 (e.g., a clogged filter) because the on-site information is the same as usual.

[0065] (Modification 10) Fig. 17 is an example of a status display screen 7 according to Modification 10. As shown in Fig. 17, the status display screen 7 may have an advice display section 73 that displays advice regarding the operation of the air conditioner 1 or the ventilation device 2. The control device 54 of the terminal device 5 generates advice regarding the operation of the air conditioner 1 or the ventilation device 2 based on the environmental information and the operating information, and displays it on the status display screen 7. For example, in the case of Fig. 17, the control device 54 ２ Since the concentration will be high, advice urging the operation of the ventilation device 2 from 11:00 is generated and displayed on the advice display unit 73.

[0066] When the environmental information falls outside a preset range, the control device 54 displays advice to encourage the operation or stop of the air conditioning device 1 or the ventilation device 2, or to change the set temperature or set air volume, before the time when the environmental information falls outside the range. Also, when there are multiple pieces of environmental information, advice may be generated for each piece of environmental information, and one of the multiple pieces of advice may be displayed according to the priority of the environmental information set by the user. For example, ２ If the indoor temperature is more important than the concentration, advice regarding the indoor temperature is displayed. The priority of each piece of information can be set by the user.

[0067] This makes it possible to clearly prompt the user to control the air conditioning device 1 to improve comfort. Furthermore, in addition to the advice, the advice display unit 73 may display an operation unit for setting a schedule for the air conditioning device 1 and the ventilator 2, or a link for jumping to a screen for setting a schedule. This allows the user to easily set a schedule in accordance with the advice. Furthermore, the control device 54 may display, on the status display unit 71, a prediction of environmental information when the control in accordance with the advice is implemented, and a prediction of environmental information when the control in accordance with the advice is not implemented.

[0068] (Modification 11) FIG. 18 shows an example of the status display screen 7 according to Modification 11. In the above-described embodiment and modifications, the terminal device 5 displays the operating information and environmental information for the past day selected by the user. However, the terminal device 5 may display the operating information and environmental information for the current day in real time. In this case, the terminal device 5 may receive the operating information and environmental information directly from the air conditioning apparatus 1, the ventilation apparatus 2, and the information acquisition device 3, or may receive the operating information and environmental information in real time via the remote controller 4. For example, the terminal device 5 periodically requests the operating information and environmental information from the remote controller 4, receives the operating information and environmental information from the remote controller 4, generates the status display screen 7, and displays it on the display device 52. If the horizontal axis of the status display screen 7 is in units of one hour, the terminal device 5 requests the operating information and environmental information from the remote controller 4 every hour. Alternatively, the remote controller 4 may voluntarily transmit the operating information and environmental information to the terminal device 5. This allows the state of the indoor air R in a hospital or beauty salon to be displayed, thereby highlighting the effectiveness of infection control measures. Furthermore, the current CO ２ Since environmental information such as concentration and power consumption can be visualized, it is possible to influence the operation of the air conditioning device 1 or the ventilation device 2 by the user.

[0069] 18 , the status display screen 7 may also have an operation unit 74 that is operated to control the operation of the air conditioning apparatus 1 or the ventilation apparatus 2. The operation unit 74 includes a plurality of operation buttons for operating, stopping, and setting the temperature of the air conditioning apparatus 1, and for operating, stopping, and setting the air volume of the ventilation apparatus 2. This allows the user to quickly control the operation of the air conditioning apparatus 1 or the ventilation apparatus 2 after checking the current status.

[0070] Furthermore, the control device 54 of the terminal device 5 may predict future changes in the environmental information and display the prediction results on the status display screen 7 to prompt the user to take proactive action. ２ By displaying a prediction that the concentration is likely to exceed the threshold, the user can proactively start operating the ventilation device 2 or increase the airflow rate.

[0071] The control device 54 of the terminal device 5 may predict future environmental information using a trained model that uses current driving information and environmental information as input data and future environmental information as output data. The trained model is constructed by learning past driving information and environmental information and is stored in the storage device 55. Note that prediction of future environmental information may be performed by a device other than the terminal device 5, such as the remote controller 4 or a cloud server.

[0072] (Variation 12) Fig. 19 is an example of a status display screen 7 according to Variation 12. In the above-described embodiment and variations, the time-series data of the operating information and the time-series data of the environmental information are displayed overlapping each other, but the time-series data of the operating information and the time-series data of the environmental information may be displayed so as not to overlap each other. In the example of Fig. 19, in the status display unit 71, an icon indicating the operating mode of the air conditioning device 1, which is the operating information, and the set temperature are displayed in a position that does not overlap with a graph of the indoor temperature, which is the environmental information. This makes the display on the status display unit 71 even easier to see.

[0073] (Modification 13) Fig. 20 is an example of the status display screen 7 according to Modification 13. In the above-described embodiment and modifications, time-series data of a plurality of environmental information items are displayed in an overlapping manner, but these items may also be displayed individually. The status display unit 71 of this modification has a first status display unit 71a including the operating information of the air conditioning device 1 and the indoor temperature, and a second status display unit 71b including the operating information of the ventilation device 2 and the CO ２ and a second status display section 71b including the concentration. The first status display section 71a and the second status display section 71b have the same time axis but are displayed without overlapping. Furthermore, an icon and set temperature indicating the operating information of the air conditioning device 1, and an icon and air volume indicating the operating information of the ventilation device 2, are displayed outside the area where the environmental information graph is displayed. Here, the "area where the environmental information graph is displayed" refers to the inside of a frame formed by the time axis and the axis of the environmental information data. This allows multiple pieces of information to be displayed without overlapping, making the display of the status display section 71 even easier to read. Note that multiple pieces of environmental information may be displayed on separate tabs, which can be switched between.

[0074] Embodiment 2. Embodiment 2 will be described. The display system 100 of Embodiment 2 differs from Embodiment 1 in the content of the status display screen 7A displayed on the terminal device 5. The configuration of the display system 100 is the same as that of Embodiment 1. FIG. 21 is an example of a status display screen 7A according to Embodiment 2. As shown in FIG. 21 , a status display section 71A on the status display screen 7A of this embodiment includes time series data of the operating information of the air conditioning device 1, time series data of the environmental information, and also time series data 710 of the comfort level. The time series data 710 of the comfort level is displayed on the same time axis as the time series data of the operating information and the time series data of the environmental information.

[0075] The comfort level is the comfort level in the room R and is calculated by the control device 54 of the terminal device 5. The control device 54 calculates the comfort level for each time period based on the operation information and environmental information of the air conditioner 1 received from the remote controller 4. Specifically, the control device 54 compares the difference ΔT, which is the indoor temperature included in the environmental information minus the set temperature of the air conditioner 1 included in the operation information, with a preset threshold, and classifies the comfort level into three levels: "high (comfortable)," "medium (normal)," and "low (uncomfortable)." For example, during cooling operation, the control device 54 classifies the comfort level as "low (uncomfortable)" if ΔT is 4°C or higher, "medium (normal)" if ΔT is 2°C or higher but less than 4°C, and "high (comfortable)" if ΔT is less than 2°C. Furthermore, during heating operation, the control device 54 classifies the comfort level as "low (uncomfortable)" if ΔT is less than -4°C, "medium (normal)" if ΔT is -4°C or higher but less than -2°C, and "high (comfortable)" if ΔT is -2°C or higher.

[0076] The comfort level time-series data 710 is displayed using icons or characters indicating the comfort level. In the example of FIG. 21 , the comfort level is expressed using facial expressions. Note that the icons indicating the comfort level are not limited to the example of FIG. 21 , and any icon that allows identification of "high (comfortable)," "medium (normal)," and "low (uncomfortable)" may be used. Furthermore, "high (comfortable)," "medium (normal)," and "low (uncomfortable)" may be expressed by using different colors for the icons indicating the comfort level. Furthermore, the comfort level may be displayed in two or fewer levels, or four or more levels, or may be displayed using characters or numerical values.

[0077] According to this embodiment, by displaying the time series data of driving information, the time series data of environmental information, and the time series data of comfort level 710, the user can intuitively recognize which times they need to be careful about and which time settings they should review.

[0078] 21, a case has been described in which a comfort level based on the indoor temperature related to the operation of the air conditioning device 1 is displayed. However, the status display unit 71A of this embodiment can also display a comfort level based on the CO ２ In this case, the control device 54 may display the comfort level based on the CO concentration included in the environmental information received from the remote controller 4. ２ Based on the concentration, the control device 54 calculates the comfort level for the ventilation device 2 at each time. ２ The control device 54 compares the concentration with a preset threshold value and classifies the comfort level into three levels: "high (comfortable)", "medium (normal)", and "low (uncomfortable)". ２ If the concentration is 1100 ppm or higher, the comfort level is rated as "low (uncomfortable)", if it is 1000 ppm or higher but less than 1100 ppm, it is rated as "medium (average)", and if it is less than 1000 ppm, it is rated as "high (comfortable)".

[0079] The control device 54 may also calculate a comfort level from a plurality of pieces of driving information and environmental information and display it on the status display unit 71A. For example, the control device 54 may calculate a comfort level based on the indoor temperature, CO ２The control device 54 may calculate a comfort level based on the concentration, humidity, and PM2.5, respectively, and display the lowest comfort level as a representative comfort level on the status display unit 71A. Alternatively, the control device 54 may correct the comfort level calculated based on the environmental information using the operating information. Specifically, the control device 54 may correct the comfort level based on the indoor temperature according to the set airflow rate of the ventilation device 2 and display the corrected comfort level on the status display unit 71A. For example, even when the indoor temperature is the same, the perceived temperature changes depending on whether or not there is airflow. Therefore, when the air conditioning device 1 is operating in heating mode, the control device 54 corrects the comfort level lower as the set airflow rate of the ventilation device 2 increases. When the air conditioning device 1 is operating in cooling mode, the control device 54 corrects the comfort level higher as the set airflow rate of the ventilation device 2 increases. This allows a comfort level that closely matches the conditions in the room R to be calculated.

[0080] In addition, when one comfort level is calculated from a plurality of pieces of driving information and environmental information and displayed on the status display unit 71A in this way, the display of the comfort level may be changed depending on the environmental information on which it is based. For example, the color of the comfort level based on the indoor temperature and the color of the CO ２ The color of the comfort level may be different depending on the concentration. Alternatively, when the comfort level icon on the status display unit 71A is tapped, the underlying environmental information may be displayed as an icon or text. By calculating the comfort level from multiple pieces of operational information and environmental information, it is possible to display a comfort level that takes into account various comfort levels in the interior R, making it easier to determine which device settings need to be reviewed. Furthermore, the control device 54 may calculate the comfort level using information such as the outside air temperature or weather. Also, a comfort level item may be provided on the selection button 72, and the comfort level may be displayed only when the comfort level is selected.

[0081] (Modification 14) Fig. 22 is an example of a status display screen 7A according to Modification 14. As shown in Fig. 22, on the status display screen 7A, time-series data 710 of comfort level may be displayed outside the graph of environmental information. Furthermore, the display of each time on the time axis may be made different depending on the comfort level. When the display of the time axis is made different depending on the comfort level, the display of the icon indicating the comfort level may be omitted. Furthermore, an index for calculating the comfort level (the difference ΔT between the indoor temperature and the set temperature, or CO ２In this case, it is easier for the user to determine which time setting should be reviewed.

[0082] (Modification 15) FIG. 23 is an example of a status display screen 7A according to Modification 15. As shown in FIG. 23 , the status display screen 7A may display time-series data 710 of comfort levels for multiple days. The multiple days are selected using the date selection screen 6 of Embodiment 1. In FIG. 23 , three days' worth of time-series data 710 of comfort levels is displayed, but the user can arbitrarily select how many days to display. Also, in FIG. 23 , the status display unit 71A displays a graph of environmental information for one selected day from multiple days. However, graphs for multiple days may be displayed overlapping each other, or graphs for each day may be displayed individually on one screen. This makes it easier to compare the driving status and comfort level for each day and makes it easier to determine when it is time to review the settings.

[0083] (Modification 16) Fig. 24 is an example of a status display screen 7A according to Modification 16. As shown in Fig. 24, the status display screen 7A displays time-series data 710a of the comfort level based on the indoor temperature and CO ２ The time-series data 710b of the comfort level based on the concentration may be displayed on one screen. This allows the comfort level for each environmental information item to be compared, and can serve as an indicator of how the settings should be revised.

[0084] (Modification 17) Fig. 25 is an example of a status display screen 7A according to Modification 17. As shown in Fig. 25, on the status display screen 7A, the operating information of the air conditioning device 1 and the ventilation device 2 is displayed in the form of a comfort level based on the indoor temperature and CO ２ Alternatively, the comfort level based on the concentration may be displayed in the area where the comfort level is displayed. In Fig. 25, only the comfort level for one selected day out of multiple days (9 / 19 in the case of Fig. 25) is displayed as an icon, and the operating information for the air conditioning device 1 and the ventilator 2 is displayed in the area where the comfort level icon and the time axis are displayed. This makes it easier to understand the relationship between the operating information and the comfort level.

[0085] The above is a description of the embodiments, but the present disclosure is not limited to the above embodiments and can be modified or combined in various ways without departing from the spirit of the present disclosure. For example, embodiments 1 and 2 and variations 1 to 17 can be combined in any way. For example, embodiment 2 can be combined with variation 10, and when the user taps the icon indicating a "low (uncomfortable)" comfort level, advice regarding the operation of the air conditioning device 1 or the ventilation device 2, an operation unit for setting the air conditioning device 1 and the ventilation device 2, or a link to a screen for performing the operation can be displayed. This makes it possible to easily change the setting for the time during which the user feels uncomfortable.

[0086] Furthermore, in the above embodiment, the display system 100 is configured to include the air conditioning device 1 and the ventilation device 2, but it is sufficient for the display system 100 to include at least one of the air conditioning device 1 and the ventilation device 2. The terminal device 5 may display at least one of the operating information of the air conditioning device 1 or the operating information of the ventilation device 2 together with environmental information. Alternatively, the display system 100 may include an air purifier in addition to the air conditioning device 1 and the ventilation device 2, and display the operating information of the air purifier together with environmental information.

[0087] In the above embodiment, the information acquisition device 3 is provided separately from the air conditioning device 1, the ventilation device 2, and the remote controller 4 to acquire environmental information, but this is not limiting. For example, the information acquisition device 3 may be an indoor temperature sensor built into the air conditioning device 1, or a CO ２ In this case, the remote controller 4 receives environmental information in addition to the operating information from the air conditioning apparatus 1 or the ventilation apparatus 2.

[0088] Furthermore, in the above embodiment, the storage device 45 of the remote controller 4 is configured to store the operation information of the air conditioning device 1 and the ventilator 2 and the environmental information of the room R, but the operation information and the environmental information may be stored in other external devices such as a cloud server. In this case, the terminal device 5 acquires the operation information and the environmental information by wirelessly communicating with the external device.

[0089] In the above embodiment, the status display screen 7 is generated in the control device 54 of the terminal device 5, but the status display screen 7 may be generated in the remote controller 4, a cloud server, or the like, and transmitted to the terminal device 5. Furthermore, in the above second embodiment, the comfort level is calculated in the control device 54 of the terminal device 5, but the comfort level may be calculated in the control device 44 of the remote controller 4, a control device provided in the cloud server, or the like, and transmitted to the terminal device 5. When the status display screen 7 is generated or the comfort level is calculated in the terminal device 5, the load on the remote controller 4 can be reduced, and there is no need to connect to a cloud server via the Internet, etc., which is convenient. On the other hand, when the status display screen 7 is generated or the comfort level is calculated in the cloud server, it is also possible to obtain operating information and environmental information of rooms other than the room R and perform a comparative display for each room.

[0090] Furthermore, in the above embodiment, the terminal device 5 is configured to only display the state of the room R, but the terminal device 5 may also operate the air conditioning apparatus 1 and the ventilation apparatus 2. Specifically, the control device 54 of the terminal device 5 displays an operation screen for controlling the operation of the air conditioning apparatus 1 and the ventilation apparatus 2 on the display device 52. Then, in response to input by the user on the operation screen, it transmits a control signal to the remote controller 4. The operation of the air conditioning apparatus 1 and the ventilation apparatus 2 is controlled by transmitting the control signal from the terminal device 5 from the remote controller 4 to the air conditioning apparatus 1 and the ventilation apparatus 2. This allows the user to check the control of the air conditioning apparatus 1 or the ventilation apparatus 2 to improve comfort by looking at the display on the terminal device 5, and then use the terminal device 5 to control the air conditioning apparatus 1 or the ventilation apparatus 2, improving convenience.

[0091] Furthermore, in the status display screen 7 of Modification 10, the advice display section 73 may be provided with a button for selecting whether or not to execute the advice control. When the user selects to execute the advice control, the control device 54 transmits a control signal related to the advice control to the remote controller 4. This makes it possible to easily carry out operation that reflects the advice in the air conditioning device 1 or the ventilator 2. This improves user comfort.

[0092] Furthermore, the layout of the status display section 71, the selection buttons 72, the advice display section 73, and the operation section 74 on the status display screen 7 is not limited to the above-described embodiment and modified examples. For example, the selection buttons 72 for selecting environmental information to be displayed and the selection buttons 72 for selecting driving information to be displayed may be displayed in different areas. Specifically, the selection buttons 72 for selecting environmental information may be displayed in an area near the vertical axis of the status display section 71 showing the environmental information, and the selection buttons 72 for selecting driving information may be displayed in an area near the display of the driving information (e.g., near the horizontal axis). Furthermore, a display for switching dates or a link to the date selection screen 6 may be displayed in the area displaying the date above the status display section 71. Alternatively, the layout of the status display section 71, the selection buttons 72, the advice display section 73, and the operation section 74 may be arbitrarily changed by the user. This allows the status display screen 7 to be easily operated by the user, improving convenience.

[0093] Furthermore, the icons indicating the operating information in the above-described embodiment and modified examples may be still images or videos. For example, the icon indicating the operating information of the air conditioning device 1 may be an animation that alternates between a graphic or symbol indicating cooling operation and text indicating the set temperature. Furthermore, the icon indicating the operating information of the ventilation device 2 may be an animation in which a graphic representing a fan rotates at a speed corresponding to the set airflow rate. This allows multiple pieces of operating information to be represented by a single icon, thereby reducing the display space and making the display of the status display unit 71 easier to see.

[0094] Furthermore, the display method of the operating information and the environmental information on the status display screen 7 does not have to be the same. For example, the shape, color, or thickness of the display of the operating information may be changed in conjunction with the operation of the device, or the shape, color, or thickness of the display of the operating information or environmental information of a part estimated to be in an abnormal state may be changed from the display of other parts.
