Description

Private room status display device, private room status display system, private room status display method and program

[0001] The present disclosure relates to a private room status display device, a private room status display system, a private room status display method, and a program.

[0002] In recent years, it is not uncommon for offices to have multiple individual work booths (i.e., private rooms) in addition to rooms with multiple fixed desks. In such offices, the rules are often set up so that private rooms can be used on a first-come, first-served basis, and when an employee or other user of the office wants to use a private room, they usually go to the nearest private room and check whether the room is in use.

[0003] In order to eliminate the hassle for users as described above, it would be desirable to enable users to check the usage status of private rooms from a remote location, such as with the private room management system described in Patent Document 1.

[0004] Patent No. 5759043

[0005] However, the private room management system described in Patent Document 1 requires the installation of dedicated sensors (door sensors and human presence sensors) in the private rooms to obtain information on the usage status of the private rooms, which poses the problem of high system implementation and operating costs.

[0006] Therefore, there is a need for new technology that allows users to check the occupancy status of private rooms from a distance.

[0007] The present disclosure has been made in consideration of the above-mentioned situation, and aims to provide a private room status display device, etc., which allows the usage status of a private room to be checked from a remote location and can be reduced in cost.

[0008] In order to achieve the above-mentioned object, the private room status display device of the present disclosure comprises an environmental information acquisition means for acquiring environmental information of the private room from an environmental adjustment device that adjusts the environment of the private room, a usage status estimation means for estimating the current usage status of the private room based on the acquired environmental information, and a usage status display means for displaying the estimated usage status of the private room.

[0009] This allows the usage status of private rooms to be checked from a distance, which also helps reduce costs.

[0011] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings.

[0012] (Embodiment 1) Fig. 1 is a diagram showing the overall configuration of a private room status display system 1 in embodiment 1. The private room status display system 1 is a system that displays the usage status of multiple private rooms provided in an office building, and includes a private room status display device 2 and an indoor unit 3 installed in each private room.

[0013] <Private Room Status Display Device 2> The private room status display device 2 is an example of a private room status display device according to the present disclosure. The private room status display device 2 is installed in or near a room in which multiple fixed seats are provided. As shown in FIG. 2 , the private room status display device 2 includes a display 20, a communication interface 21, a CPU (Central Processing Unit) 22, a ROM (Read-Only Memory) 23, a RAM (Random-Access Memory) 24, and an auxiliary storage device 25. These components are interconnected via a bus 26.

[0014] The display 20 includes a display device such as a liquid crystal display, an organic EL (Electroluminescence) display, etc. The display 20 displays a screen showing the usage status of each private room under the control of the CPU 22. The communication interface 21 is hardware for communicating with each indoor unit 3.

[0015] The CPU 22 provides overall control over the private room status display device 2. Details of the functions of the private room status display device 2 realized by the CPU 22 will be described later. The ROM 23 stores multiple pieces of firmware and data used when these pieces of firmware are executed. The RAM 24 is used as a work area for the CPU 22. The auxiliary storage device 25 is composed of a readable / writable nonvolatile semiconductor memory, a HDD (Hard Disk Drive), etc. Examples of the readable / writable nonvolatile semiconductor memory include an EEPROM (Electrically Erasable Programmable Read-Only Memory) and a flash memory. The auxiliary storage device 25 stores a private room status display program, which is a program for displaying the usage status of each private room, and data used when the private room status display program is executed.

[0016] The private room status display device 2 can acquire the private room status display program or an update program for updating the private room status display program from another device via communication. These programs can also be stored and distributed on a computer-readable recording medium such as a CD-ROM (Compact Disc Read-Only Memory), a DVD (Digital Versatile Disc), a magneto-optical disk, a USB (Universal Serial Bus) memory, a HDD (HDD), a SSD (Solid-State Drive), or a memory card. When such a recording medium is directly or indirectly attached to the private room status display device 2, the private room status display device 2 can read the private room status display program or an update program from the recording medium and install it on itself.

[0017] <Indoor unit 3> The indoor unit 3 is an example of an environmental conditioning device according to the present disclosure. The indoor unit 3 is a ceiling-mounted or wall-mounted indoor unit that is installed in each individual room and conditions the air in that room. The indoor unit 3 is connected to an outdoor unit (not shown) installed outdoors via a transmission line (not shown) so that they can communicate with each other, and is also connected by a refrigerant pipe (not shown) for circulating a refrigerant.

[0018] Although not shown, the indoor unit 3 includes a control circuit, actuators such as a fan and a solenoid valve, a heat exchanger, a temperature sensor for measuring the room temperature, a humidity sensor for measuring the room humidity, and a communication interface for communicating with the private room status display device 2. In response to a request from the private room status display device 2 at regular intervals, the indoor unit 3 transmits environmental data to the private room status display device 2, including its own device ID (identifier) ​​and the measured temperature and humidity values. The private room temperature and humidity are each examples of environmental information related to the present disclosure. The device ID is information for identifying each indoor unit 3, such as a serial number. The indoor unit 3 may also transmit environmental data to the private room status display device 2 at regular intervals.

[0019] <Functional Configuration of Private Room Status Display Device 2> Fig. 3 is a block diagram showing the functional configuration of the private room status display device 2. As shown in Fig. 3, the private room status display device 2 includes an environmental data acquisition unit 200, a usage status estimation unit 201, and a usage status display unit 202. These functional units are realized when the CPU 22 executes the private room status display program stored in the auxiliary storage device 25.

[0020] The environmental data acquisition unit 200 is an example of an environmental information acquisition means according to the present disclosure. The environmental data acquisition unit 200 acquires environmental data from each indoor unit 3 at regular intervals (e.g., every minute). Specifically, the environmental data acquisition unit 200 transmits a command to each indoor unit 3 requesting the transmission of environmental data at regular intervals, and receives and acquires the environmental data sent from each indoor unit 3 in response to the command. When the environmental data acquisition unit 200 acquires environmental data from an indoor unit 3, it references the private room information storage unit 250 and acquires the private room ID corresponding to the device ID included in the environmental data. The environmental data acquisition unit 200 then sorts the acquired environmental data by private room ID in chronological order and stores the data in the environmental data storage unit 251.

[0021] The private room information storage unit 250 is a memory area provided by the auxiliary storage device 25, and stores private room information. As shown in FIG. 4, the private room information includes a private room ID, an equipment ID, a name, and location information. The private room ID is an ID assigned in advance to identify each private room. The name is a nickname for the private room. The location information is information indicating the location of the private room, such as the floor number. The private room information is written in advance to the private room information storage unit 250 by an administrator. The environmental data storage unit 251 is a memory area provided by the auxiliary storage device 25, and stores the history of environmental data for each private room.

[0022] The usage status estimation unit 201 is an example of a usage status estimation means according to the present disclosure. The usage status estimation unit 201 estimates the usage status of each private room based on the latest environmental data for each private room and thresholds stored in the threshold storage unit 252. The threshold storage unit 252 is an example of an estimated environmental information storage means according to the present disclosure. The threshold storage unit 252 is a memory area provided by the auxiliary storage device 25 and stores thresholds used in estimating the usage status. The thresholds include a temperature threshold and a humidity threshold, each of which has a predetermined value according to the season (summer, winter, intermediate season, etc.) and the time of day and is written in advance to the threshold storage unit 252 by an administrator. The temperature threshold and the humidity threshold are each an example of estimated environmental information according to the present disclosure.

[0023] The usage status estimation unit 201 reads the temperature threshold and humidity threshold corresponding to the current season and time from the threshold storage unit 252. Then, for one of the rooms selected sequentially from all the rooms, the usage status estimation unit 201 compares the latest temperature with the read temperature threshold, and if the latest temperature is higher than the temperature threshold, it estimates that the room is in use. This estimation is based on the fact that the human body is a heat source, and therefore the temperature of a room where a person is present is expected to rise.

[0024] On the other hand, if the latest temperature is equal to or lower than the temperature threshold, the usage status estimation unit 201 compares the latest humidity in the room with the read humidity threshold, and if the latest humidity is higher than the humidity threshold, it estimates that the room is in use. This estimation is based on the fact that the human body emits water vapor from the skin, so the humidity in a room where a person is present is expected to increase.

[0025] Furthermore, the usage status estimation unit 201 estimates that a private room whose latest temperature is equal to or lower than the temperature threshold value and whose latest humidity is equal to or lower than the humidity threshold value is not in use, i.e., is vacant. The usage status estimation unit 201 notifies the usage status display unit 202 of the private room ID of the estimated private room and the estimation result.

[0026] The usage status display unit 202 is an example of a usage status display means according to the present disclosure. The usage status display unit 202 displays the usage status of each private room in a predetermined manner on the display 20 based on the estimation result of the usage status of each private room by the usage status estimation unit 201. Note that how the usage status is displayed is a matter of design discretion. For example, the usage status display unit 202 may display the usage status of each private room in text (e.g., "Personal booth 201 in use," "Personal booth 202 vacant," etc.). Alternatively, the usage status display unit 202 may display the usage status of each private room using an icon.

[0027] <Private Room Status Display Processing> Fig. 5 is a flowchart showing the procedure of private room status display processing executed by the private room status display device 2. The private room status display device 2 periodically (for example, every minute) executes the following private room status display processing.

[0028] (Step S100) The private room status display device 2 acquires environmental data from the indoor units 3 installed in each private room. After that, the process of the private room status display device 2 proceeds to step S101.

[0029] (Step S101) The private room status display device 2 reads out the temperature threshold and humidity threshold corresponding to the current season and time from the threshold storage unit 252. After that, the process of the private room status display device 2 proceeds to step S102.

[0030] (Step S102) The private room status display device 2 selects one private room to be the target of usage status estimation from all private rooms. After that, the process of the private room status display device 2 proceeds to step S103.

[0031] (Step S103) The private room status display device 2 determines whether the latest temperature of the selected private room is higher than the read temperature threshold. If the latest temperature is not higher than the temperature threshold (Step S103; NO), the process of the private room status display device 2 proceeds to Step S104. On the other hand, if the latest temperature is higher than the temperature threshold (Step S103; YES), the process of the private room status display device 2 proceeds to Step S105.

[0032] (Step S104) The private room status display device 2 determines whether the latest humidity of the selected private room is higher than the read humidity threshold. If the latest humidity is higher than the humidity threshold (Step S104; YES), the processing of the private room status display device 2 proceeds to Step S105. On the other hand, if the latest humidity is not higher than the humidity threshold (Step S104; NO), the processing of the private room status display device 2 proceeds to Step S106.

[0033] (Step S105) The private room status display device 2 estimates that the private room is in use. After that, the process of the private room status display device 2 proceeds to step S107.

[0034] (Step S106) The private room status display device 2 estimates that the private room is vacant. After that, the process of the private room status display device 2 proceeds to step S107.

[0035] (Step S107) The private room status display device 2 determines whether there are any unselected private rooms to be used for estimating usage status. If there are any unselected private rooms (Step S107; YES), the process of the private room status display device 2 returns to Step S102. On the other hand, if there are no unselected private rooms (Step S107; NO), the process of the private room status display device 2 proceeds to Step S108.

[0036] (Step S108) Based on the estimation result of the usage status of each private room, the private room status display device 2 displays the usage status of each private room in a predetermined manner on the display 20. Thereafter, the private room status display device 2 ends the private room status display process for this cycle.

[0037] As described above, in the private room status display system 1 according to the present embodiment, the private room status display device 2 estimates and displays the usage status of each private room based on the temperature and humidity of each private room. This allows the user to easily check the usage status of each private room from a remote location without having to travel to the location to check.

[0038] In addition, since the private room status display device 2 acquires temperature and humidity (i.e., environmental information) from the indoor units 3 installed in each private room, costs can be reduced in introducing and operating the private room status display system 1.

[0039] (Variation 1) The usage status estimation unit 201 may estimate that a private room is in use if the latest temperature is greater than a value obtained by adding a predetermined value (hereinafter referred to as the "first value") to the temperature threshold. The usage status estimation unit 201 may also estimate that a private room is in use if the latest humidity is greater than a value obtained by adding a predetermined value (hereinafter referred to as the "second value") to the humidity threshold. In this case, the usage status estimation unit 201 estimates that a private room is vacant if the latest temperature is equal to or less than the value obtained by adding the first value to the temperature threshold and the latest humidity is equal to or less than the value obtained by adding the second value to the humidity threshold.

[0040] (Variant 2) The usage status estimation unit 201 may estimate that the private room is in use if the latest temperature is greater than the temperature threshold and the latest humidity is greater than the humidity threshold, and may estimate that the private room is vacant if the latest temperature is equal to or less than the temperature threshold or the latest humidity is equal to or less than the humidity threshold.

[0041] (Modification 3) In the above embodiment, the indoor unit 3 is exemplified as an environmental adjustment device, but other examples of the environmental adjustment device include an air purifier, a ventilation device, an air conditioning ventilation device, etc. ２ If a sensor is installed to measure the concentration, ２ In this case, the threshold value storage unit 252 stores the CO concentration according to the season and time. ２ The concentration threshold is written in advance by the administrator. ２ The concentration is the CO 2 concentration corresponding to the current season and time read from the threshold storage unit 252. ２ If the concentration is higher than the threshold value, the room is determined to be in use. ２ The concentration is CO ２ If the concentration is equal to or less than the concentration threshold, the usage status estimation unit 201 determines that the private room is vacant.

[0042] Furthermore, if the environmental adjustment device installed in the private room is equipped with a thermal image sensor such as an infrared thermograph, the thermal image acquired by the thermal image sensor can be used as environmental information. In this case, the usage status estimation unit 201 analyzes the latest thermal image and determines that the private room is in use if it detects the presence of a person, and determines that the private room is vacant if it does not detect the presence of a person.

[0043] (Modification 4) In order to monitor the environmental conditions, temperature, humidity, CO ２ In the case where a sensor for measuring environmental information such as concentration is installed, the usage status estimation unit 201 may estimate the usage status of the private room based on the environmental information acquired from the sensor.

[0044] (Variant 5) The private room status display device 2 may pre-store in the auxiliary storage device 25 the trend of time series changes in environmental information such as temperature and humidity when a person enters a private room, and the trend of time series changes in environmental information such as temperature and humidity when a person leaves a private room, as an entry pattern and an exit pattern, respectively, and may estimate the usage status of the private room by estimating that a person has entered the private room if the time series changes in the acquired environmental information match the entry pattern, and that a person has left the private room if the time series changes in the acquired environmental information match the exit pattern.

[0045] (Variation 6) As shown in FIG. 6 , the private room status display device 2 may further include a threshold estimation unit 203 that estimates a threshold value. The threshold estimation unit 203 is an example of an environmental information estimation means according to the present disclosure. The threshold estimation unit 203 estimates the temperature for each future time period for each private room based on the latest temperature and the operation plan information stored in the operation plan information storage unit 253. The operation plan information storage unit 253 is an example of an operation plan information storage unit according to the present disclosure. The operation plan information storage unit 253 is a memory area provided by the auxiliary storage device 25. The operation plan information is, for example, information that specifies the date and time for switching between operation / stop, set temperature, and operation mode (cooling, heating, etc.) for each indoor unit 3. The threshold estimation unit 203 stores the temperature for each time period estimated for each private room in the threshold storage unit 252 as the temperature threshold for each time period for each private room.

[0046] Furthermore, the threshold estimation unit 203 estimates the humidity for each future hour for each individual room based on the latest humidity and the operation plan information, and stores the humidity estimated for each individual room at each hour as the humidity threshold for each individual room in the threshold storage unit 252. When estimating the usage status of a single individual room, the usage status estimation unit 201 reads out the temperature threshold and humidity threshold corresponding to the individual room and the current time from the threshold storage unit 252. The usage status estimation unit 201 then compares the latest temperature of the individual room with the read-out temperature threshold, and, if necessary, compares the latest humidity of the individual room with the read-out humidity threshold, thereby estimating the usage status of the individual room.

[0047] In this way, the temperature threshold and humidity threshold are values ​​estimated based on the operation plan information, and therefore are highly accurate, which improves the accuracy of estimation of the usage status of the private rooms by the usage status estimation unit 201. Note that the threshold estimation unit 203 may further take into account the current outside air conditions (temperature, humidity), weather forecasts, etc., to estimate the temperature and humidity of each private room at each future time.

[0048] (Variation 7) All or part of the functional units (see FIG. 3) of the private room status display device 2 may be realized by dedicated hardware, such as a single circuit, a composite circuit, a programmed processor, an ASIC (Application-Specific Integrated Circuit), an FPGA (Field-Programmable Gate Array), or a combination thereof.

[0049] The technical ideas according to the above-described modifications may be realized independently or in appropriate combination.

[0050] (Embodiment 2) Fig. 7 is a diagram showing the overall configuration of a private room status display system 1A in embodiment 2. The private room status display system 1A is a system that displays the usage status of multiple private rooms provided in an office building, and includes a private room status estimation device 4, an indoor unit 5 installed in each private room, and a user terminal 6.

[0051] <Private Room Status Estimation Device 4> The private room status display device 4 is an example of a private room status estimation device according to the present disclosure.

In response to a request from the private room situation estimation device 4 at regular intervals, the indoor unit 5 transmits environmental data including its own device ID and the measured temperature and humidity values ​​to the private room situation estimation device 4. Note that the indoor unit 5 may also transmit environmental data to the private room situation estimation device 4 on its own accord at regular intervals.

[0057] <User Terminal 6> The user terminal 6 is an example of a display device according to the present disclosure. The user terminal 6 is an electronic device carried by a user who is an associate of the office building, and is, for example, a smart device such as a smartphone or tablet terminal. As shown in FIG. 9 , the user terminal 6 includes a display 60, an operation reception unit 61, a communication interface 62, a CPU 63, a ROM 64, a RAM 65, and an auxiliary storage device 66. These components are connected to each other via a bus 67.

[0058] The display 60 includes a display device such as a liquid crystal display, an organic EL display, etc. The display 60 displays various screens etc. in response to user operations under the control of the CPU 63. The operation reception unit 61 includes one or more input devices such as a push button, a touch panel, a touch pad, etc., receives operation input from the user, and outputs a signal related to the received operation to the CPU 63.

[0059] The communication interface 62 is hardware for communicating with the private room situation estimation device 4. The CPU 63 performs overall control of the user terminal 6. The ROM 64 stores multiple pieces of firmware and data used when these pieces of firmware are executed. The RAM 65 is used as a work area for the CPU 63.

These programs can also be stored and distributed on a computer-readable recording medium such as a CD-ROM, DVD, optical magnetic disk, USB memory, HDD, SSD, or memory card. When such a recording medium is directly or indirectly attached to the user terminal 6, the user terminal 6 can read the private room usage status presentation app or the update program from the recording medium and install it on the user terminal 6.

[0062] <Functional Configuration of Private Room Status Estimation Device 4> Fig. 10 is a block diagram showing the functional configuration of the private room status estimation device 4. As shown in Fig. 10, the private room status estimation device 4 includes an environmental data acquisition unit 400, a usage status estimation unit 401, and a usage status display instruction unit 402. These functional units are realized by the CPU 42 executing the above-mentioned private room status estimation program stored in the auxiliary storage device 45.

[0063] The environmental data acquisition unit 400 is an example of an environmental information acquisition means according to the present disclosure. The environmental data acquisition unit 400 acquires environmental data from each indoor unit 5 at regular intervals (e.g., every minute). Specifically, the environmental data acquisition unit 400 transmits a command to each indoor unit 5 at regular intervals requesting the transmission of environmental data, and receives and acquires the environmental data sent from each indoor unit 5 in response to the command. Upon acquiring environmental data from an indoor unit 5, the environmental data acquisition unit 400 references the private room information storage unit 450 and acquires the private room ID corresponding to the device ID included in the environmental data. The environmental data acquisition unit 400 then sorts the acquired environmental data by private room ID in chronological order and stores the data in the environmental data storage unit 451.

[0064] The private room information storage unit 450 is a memory area provided by the auxiliary storage device 45, and stores private room information. The configuration of the private room information is similar to the private room information stored in the private room information storage unit 250 in embodiment 1 (see FIG. 4). The private room information is written in advance to the private room information storage unit 450 by an administrator. The environmental data storage unit 451 is a memory area provided by the auxiliary storage device 45, and stores the history of environmental data for each private room.

[0065] The usage status estimation unit 401 is an example of a usage status estimation means according to the present disclosure. The usage status estimation unit 401 estimates the usage status of each private room based on the latest environmental data for each private room and thresholds stored in the threshold storage unit 452. The threshold storage unit 452 is a memory area provided by the auxiliary storage device 45 and stores thresholds used in estimating the usage status. The thresholds include a temperature threshold and a humidity threshold, and values ​​corresponding to the season (summer, winter, intermediate season, etc.) and the time of day are determined in advance and written in the threshold storage unit 452 by an administrator.

[0066] The usage status estimation unit 401 reads out the temperature threshold and humidity threshold corresponding to the current season and time from the threshold storage unit 452. Then, for one of the rooms selected sequentially from all the rooms, the usage status estimation unit 401 compares the latest temperature with the read temperature threshold, and if the latest temperature is higher than the temperature threshold, it estimates that the room is in use.

[0067] On the other hand, if the latest temperature is below the temperature threshold, the usage status estimation unit 401 compares the latest humidity in the room with the read humidity threshold, and if the latest humidity is higher than the humidity threshold, it estimates that the room is in use.

[0068] The usage status estimation unit 401 estimates that a room whose latest temperature is equal to or lower than the temperature threshold and whose latest humidity is equal to or lower than the humidity threshold is not in use, i.e., is vacant. The usage status estimation unit 401 notifies the usage status display instruction unit 402 of the room ID of the estimated room and the estimation result.

[0069] The usage status display instruction unit 402 is an example of a usage status information transmission means according to the present disclosure. The usage status display instruction unit 402 generates usage status information indicating the usage status of each private room based on the estimation result of the usage status of each private room by the usage status estimation unit 401, and transmits the generated usage status information to the user terminal 6 of the user, thereby instructing the user terminal 6 to display the usage status of each private room. When the user terminal 6 receives the usage status information under the operation of the private room usage status presentation app, it displays the usage status of each private room on the display 60 in a predetermined manner based on the received usage status information.

[0070] 11 is a flowchart showing the procedure of the private room situation estimation process executed by the private room situation estimation device 4. The private room situation estimation device 4 periodically (for example, every minute) executes the following private room situation estimation process.

[0071] (Step S200) The private room situation estimation device 4 acquires environmental data from the indoor units 5 installed in each private room. After that, the process of the private room situation estimation device 4 proceeds to step S201.

[0072] (Step S201) The private room situation estimation device 4 reads the temperature threshold and humidity threshold corresponding to the current season and time from the threshold storage unit 452. After that, the process of the private room situation estimation device 4 proceeds to step S202.

[0073] (Step S202) The private room status estimation device 4 selects one private room to be the target of usage status estimation from all private rooms. After that, the process of the private room status estimation device 4 proceeds to step S203.

[0074] (Step S203) The private room situation estimation device 4 determines whether the latest temperature of the selected private room is higher than the read temperature threshold. If the latest temperature is not higher than the temperature threshold (Step S203; NO), the processing of the private room situation estimation device 4 proceeds to Step S204. On the other hand, if the latest temperature is higher than the temperature threshold (Step S203; YES), the processing of the private room situation estimation device 4 proceeds to Step S205.

[0075] (Step S204) The private room situation estimation device 4 determines whether the latest humidity of the selected private room is higher than the read humidity threshold. If the latest humidity is higher than the humidity threshold (Step S204; YES), the processing of the private room situation estimation device 4 proceeds to Step S205. On the other hand, if the latest humidity is not higher than the humidity threshold (Step S204; NO), the processing of the private room situation estimation device 4 proceeds to Step S206.

[0076] (Step S205) The private room situation estimation device 4 estimates that the private room is in use. After that, the process of the private room situation estimation device 4 proceeds to step S207.

[0077] (Step S206) The private room situation estimation device 4 estimates that the private room is vacant. After that, the process of the private room situation estimation device 4 proceeds to step S207.

[0078] (Step S207) The private room situation estimation device 4 determines whether there are any private rooms that have not been selected as targets for usage status estimation. If there are any unselected private rooms (step S207; YES), the processing of the private room situation estimation device 4 returns to step S202. On the other hand, if there are no unselected private rooms (step S207; NO), the processing of the private room situation estimation device 4 transitions to step S208.

[0079] (Step S208) The private room situation estimation device 4 instructs the user terminal 6 to display the usage status of each private room. In detail, the private room situation estimation device 4 generates usage status information indicating the usage status of each private room based on the estimation result of the usage status of each private room, and transmits the generated usage status information to the user's user terminal 6. Thereafter, the private room situation estimation device 4 ends the private room situation estimation process for this cycle.

[0080] As described above, in the private room status display system 1A of this embodiment, the private room status estimation device 4 estimates the usage status of each private room based on the temperature and humidity of each private room, and transmits usage status information based on the estimated results to the user terminal 6. The user terminal 6 displays the usage status of each private room in a predetermined manner on the display 60 based on the usage status information received from the private room status estimation device 4. This allows the user to easily check the usage status of each private room from a remote location without having to travel to the site to check.

[0081] In addition, since the private room status estimation device 4 acquires temperature and humidity (i.e., environmental information) from the indoor units 5 installed in each private room, costs can be reduced in the introduction and operation of the private room status display system 1A.

[0082] Furthermore, the user can check the usage status of each private room via the user terminal 6, which greatly improves convenience for the user.

[0083] (Variation 1) All or part of the functional units (see FIG. 10 ) of the private room situation estimation device 4 may be realized by dedicated hardware, such as a single circuit, a composite circuit, a programmed processor, an ASIC, an FPGA, or a combination thereof.

[0084] (Modification 2) The technical ideas of modifications 1 to 6 in embodiment 1 can also be applied to this embodiment.

[0085] The technical ideas according to the above-described modifications may be realized independently or in appropriate combination.

[0086] The present disclosure allows various embodiments and modifications without departing from the broad spirit and scope. Furthermore, the above-described embodiments are intended to explain the present disclosure and do not limit the scope of the present disclosure. In other words, the scope of the present disclosure is defined by the claims, not the embodiments. Various modifications made within the scope of the claims and within the meaning of the disclosure equivalent thereto are considered to be within the scope of the present disclosure.
