  In the present invention, main windows that can provide a comfortable environment by ventilation are determined for each room to be managed. It can be determined that the residents had a comfortable environment by ventilation until just before the residents closed their main windows. Therefore, for example, when the outside temperature rises and the window is closed by the resident, the room temperature and the outside temperature of the room to be managed are acquired, and the room temperature and the outside temperature are values indicating the comfortable environment of the resident. Is stored in the storage device. Then, when the outside air temperature falls during operation of the air conditioner, a message is displayed to the resident that recommends opening the window. Hereinafter, embodiments of the present invention will be described in detail for each example.

(Managed room)
FIG. 1 is a block diagram illustrating an air conditioning system 10 according to the first embodiment.
The room to be managed is temperature-controlled by the air conditioner 14. The building may be a wooden single-family house or an apartment house. There can be any number of rooms to be managed, either single or multiple. The room to be managed may be a part of the room or the whole room. The on / off of the air conditioner 14 and the set temperature are controlled by the air conditioner controller 36. It can also be set by the control terminal 70 operated by the resident. The air conditioning control device 36 can be realized by a computer as will be described later.

  A main window 16 for ventilation is specified for each room to be managed. This is specified from the results of ventilation simulation, and is a window that enables effective ventilation by ventilation. The ventilation simulation will be described later with reference to FIG. Opening and closing sensors 18 are attached to the main windows 16 shown in FIG. The open / close sensor 18 outputs an open / close signal indicating whether the main window 16 is open or closed. Furthermore, it is preferable to output a signal indicating the opening of the window.

  The air conditioning control device 36 acquires the open / close signal output from the open / close sensor 18. The room to be managed is provided with a room temperature sensor 24 for measuring the room temperature, and the air conditioning controller 36 acquires a detection signal output from the room temperature sensor 24. In addition, an outside air temperature sensor 28 for measuring the outside air temperature outside the room to be managed is provided, and the air conditioning controller 36 acquires a detection signal output from the outside air temperature sensor 28. In addition to this, it is preferable to provide a humidity sensor (not shown) that measures the humidity of the room to be managed.

  When the air conditioning control device 36 detects that the main window 16 of the room to be managed is opened by the open / close signal output from the open / close sensor 18, the air conditioning control device 36 stops the operation of the air conditioner 14 in the room. Further, when it is detected that the main window 16 of the room to be managed is closed, the operation of the air conditioner 14 in the room can be started. The air conditioner may be activated automatically or may wait for the resident's input.

  When the air conditioning control device 36 detects that the main window 16 of the room to be managed is closed, the room temperature and the outside air temperature of the room to be managed are detected based on the output signals of the room temperature sensor 24 and the outside air temperature sensor 28. To get. The resident environment data including the room temperature and the outside temperature is stored in the storage device of the air conditioning control device 36. After the main window 16 of the managed room is closed, the outside temperature of the managed room is monitored, and when the outside temperature reaches a value that is a comfortable environment for the resident, A message to recommend opening the window is output by an output device such as the display 32 or the speaker 34. When the window is opened, the air conditioning control device 36 also adjusts the operating state of the ventilation device 22.

FIG. 2 is a specific hardware block diagram of the air conditioning controller 36.
The air conditioning control device 36 can be realized by a general-purpose computer. As shown in the figure, an internal bus 73 of the air conditioning control device 36 includes a CPU (Central Processing Unit) 74, a ROM (Read Only Memory) 76, a RAM (Random Access Memory) 78, and an HDD (Hard Disk) 80. The input / output interface 82 is connected.

  The input / output interface 82 is connected to the display 32, the speaker 34, the air conditioner 14, the ventilator 22, the open / close sensor 18, the room temperature sensor 24, the outside air temperature sensor 26, the communication device 35, and the like. The ROM 76, the RAM 78, and the HDD 80 constitute a storage device of the air conditioning control device 36. The CPU 74, ROM 76, and RAM 78 constitute an arithmetic processing unit. Data used for control is mainly stored and saved in the HDD 80. The computer program executed by the CPU 74 is stored in the ROM 76 or loaded into the RAM 78 and executed.

FIG. 3 is a ventilation simulation diagram 38.
When a window is provided in a building with a floor plan as shown in the figure, it is designed so that a window having an optimal area is arranged at an optimal position in consideration of the direction and environment of the building. For example, when a south wind blows in a south-facing house, a simulation is performed by a computer so that ventilation can be performed by appropriately taking in outside air when the wind passes as shown by an arrow in the figure.

  For example, when the room at the lower right in the ventilation simulation diagram 38 is the room 12 to be managed for managing the room temperature, the main window is the window indicated by the thick arrow in the figure. An open / close sensor is attached to these windows to monitor whether the resident has opened and closed all these windows, and if necessary, a message is output to the resident. Further, in a highly airtight house, in order to ensure a certain amount of ventilation even when the window is closed, a ventilation device that operates continuously for 24 hours is provided in principle. The operation of this ventilator can also be linked to the opening and closing of the window. In the following, the term “ventilator” refers to a ventilator installed for 24 hours continuous operation.

  If the window is designed based on the result of the ventilation simulation, the room temperature reached when the window is opened can be calculated from the outside air temperature and the ventilation rate. Therefore, the reliability of the message output to the resident is improved. Even when the design based on the ventilation simulation is not made, if the appropriate window for ventilation is selected and used as the main window, the following control is possible.

FIG. 4 is an explanatory diagram of the state before and after the occupant tightens the window.
In the figure, the vertical axis represents the temperature, and the horizontal axis represents the passage of time. Until the time t1 in the figure, the main window 16 of the room 12 to be managed was open. However, since both the outside temperature and room temperature rose, the resident closed the main window 16 at time t1. Prior to time t1, the operation of the ventilator 22 is stopped when all the main windows 16 are open. Therefore, the operation of the ventilator 22 was started at time t1. Further, the air conditioner 14 was not operated when the main window 16 was opened. Therefore, the operation of the air conditioner 14 was started at time t1. The room temperature and the outside temperature at time t1 are stored in the storage device of the air conditioning control device 36 as will be described later.

FIG. 5 is an explanatory diagram of the state before and after the operation of the resident.
The vertical and horizontal axes in the figure are the same as in FIG. Until the time t2 in the figure, the main window 16 of the room 12 to be managed is closed. However, since the outside temperature has dropped to the outside temperature stored in the storage device, a message is output to the resident as will be described later. The resident opens the main window 16 at time t2. When the main window 16 was closed, both the air conditioner 14 and the ventilator 22 were in operation. However, the operation of the air conditioner 14 was stopped at time t2. On the other hand, the ventilator 22 operates according to the open state of the main window 16. When the main window is fully opened, the operation of the ventilator 22 is immediately stopped. Since sufficient natural ventilation is possible, power consumption of the ventilator 22 can be saved. However, when the main window can be opened only about half, from time t2, the ventilator 22 continues the operation by reducing the air volume slightly than the full operation. Thereafter, when the main window is fully opened, the operation of the ventilator 22 is stopped. The air conditioning system 10 of the present invention performs the above control, for example.

(Air conditioner)
In FIG. 1, the air conditioner 14 may be installed inside a room to be managed, or may have a structure in which air of an appropriate temperature is supplied to the room to be managed through a duct or the like. The main window 16 is opened, outside air is taken in, and control is performed so as to obtain a comfortable thermal environment for the occupant by natural ventilation or forced ventilation. Accordingly, when the main window 16 is opened, the operation of the air conditioner 14 is stopped. When the main window 16 is closed, the air conditioner can be turned on and off by the resident's intention. Of course, the air conditioner 14 may be automatically activated at the same time as the main window 16 is closed.

  The air conditioning system 10 automatically detects a state in which a resident feels sufficiently comfortable when the main window 16 is opened and outside air is taken in without operating the air conditioner 14. In summer, when the occupant closes the open window and starts the cooling operation of the air conditioner, the environmental temperature at that time is learned. In the winter season, when the occupant closes the opened window and starts the heating operation of the air conditioner, the environmental temperature at that time is learned. In either case, until the window is closed, outside air is taken in without using the air conditioner, and it is determined that the resident is comfortable and the state is stored.

(Window and open / close sensor)
As described above, the main window 16 for ventilation is specified for each room or rooms to be managed. As shown in FIG. 1, an opening / closing sensor 18 is attached to the corresponding main window 16. The main windows 16 are all windows for the purpose of ventilation based on the result of the ventilation simulation described above. The main windows are not all provided on the wall surface of the room to be managed. It may be provided at any location on the outer wall of the building. Furthermore, when the wind for ventilation is weak or in a no-air state, the result of the ventilation simulation may be realized on the condition that the ventilation device 22 is operated. The air conditioning control device 36 acquires an open / close signal output from the open / close sensor 18 attached to the main window 16. It is preferable that the air conditioning control device 36 also controls the operation of the ventilation device 22. In the following first embodiment, a case where a specific resident uses a managed room alone will be described.

(Monitoring of room temperature and outside temperature)
In order to monitor the thermal environment of the room to be managed, a room temperature sensor 24 for measuring the room temperature of the room to be managed is provided. The temperature sensor that measures the outside air temperature is preferably one that measures the temperature around the window that takes in outside air based on the result of the ventilation simulation.

(Window opening and closing and air conditioning control)
When it is detected that the main window 16 of the room to be managed is opened, the operation of the air conditioner 14 in the room to be managed is stopped. When all the main windows 16 are not opened, the air conditioning controller 36 transmits a message notifying the windows to be opened to the display 32, the speaker 34, or the control terminal 70 owned by the resident. . When it is detected that the main window 16 of the room to be managed is closed, the operation of the air conditioner in the room to be managed can be started.

  There may be a case where the main window 16 is closed and the air conditioner 14 is not activated and is temporarily comfortable. It is preferable to control the operation start and temperature setting of the air conditioning by the control terminal 70 possessed by the resident. When the start of operation of the air conditioner 14 is instructed without closing all the main windows 16, the air conditioner controller 36 forgets to close the display 32, the speaker 34, or the control terminal 70 owned by the resident. Send a message notifying you of the window.

(Computer program and data)
FIG. 6 is a functional block diagram of the air conditioning system 10.
The air conditioning system 10 functions as each unit shown in the portion of the arithmetic processing unit 40 in the figure by executing the installed computer program. Then, data is stored in the storage device 42 for this arithmetic processing. The window opening / closing signal receiving means 52 receives the opening / closing signal 20 output from the opening / closing sensor 18 and stores it in the storage device 42. The temperature detection signal receiving means 54 monitors the open / close signal 20 and, when detecting that the main window 16 of the room to be managed is closed, the room temperature data 28 output from the room temperature sensor 24 and the outside air temperature. The outside air temperature data 29 output from the sensor 26 is received and stored in the storage device 42.

  The air conditioning operation control means 56 refers to the opening / closing signal 20 and controls the operation of the air conditioner 14. The ventilator operation control means 58 controls the operation of the ventilator 22 with reference to the open / close signal 20. The situation management data generation means 60 reads the open / close signal 20, the room temperature data 28, and the outside air temperature data 29 from the storage device 42, and the room-by-room situation management data 44 including the operation states of the air conditioning operation control means 56 and the ventilator operation control means 58. Is generated and stored in the storage device 42.

  The environmental data generating means 62 refers to the open / close signal 20, the room temperature data 28, and the outside air temperature data 29, and the room temperature and the outside air temperature when the main window 16 of the room to be managed is closed are the comfortable environment of the resident. The environmental data 46 for each resident indicating this is generated and stored in the status management data 44 for each room. Details of the storage device 42 and the resident environment data 46 will be described later with reference to FIG.

  The screen control means 64 reads the screen data 48 from the storage device 42 and displays it on the display 32. The message output means 66 monitors the open / close signal 20 and the room temperature data 28 while referring to the resident environment data 46, and the main window of the room to be managed is closed and the outside temperature is the comfortable environment of the resident. When the value is reached, the speaker 34 outputs a message to the resident to recommend opening the window. At the same time, the screen data 48 including the message can be generated and output to the screen control means 64.

  The communication control means 67 receives the air conditioning control signal of the control terminal 70 operated by the resident through the communication device 35 and adds the result to the room-by-room situation management data 44. In the second embodiment, the communication control unit 67 also reads the screen data 48 and displays it on the control terminal 70 through the communication device 35. In addition, the air conditioning operation control means 56 can output a message notifying the resident of the main windows necessary for ventilation of the room to be managed when the windows are opened and closed. This message is also output as voice or image.

FIG. 7 is an explanatory diagram showing the structure of data generated by the air conditioning system 10.
FIG. 7A shows an example of the room-by-room situation management data 44 in a state where main windows are closed. This room situation management data 44 is generated for each room to be managed by the situation management data generation means 60. Each data is distinguished by room identification information. The room-by-room situation management data 44 includes the room temperature and humidity acquired by the room temperature sensor 24 and the outside air temperature acquired by the outside air temperature sensor 26. Furthermore, the state acquired by the open / close sensor 18 is recorded for each main window of the room to be managed. In addition, upon receiving notifications from the air conditioning operation control means 56 and the ventilator operation control means 58, the operating states of the air conditioner 14 and the ventilator 22 are included.

  Furthermore, user identification information can be included in consideration of the case where a plurality of residents use the room to be examined. FIG. 7C shows an example of the room-by-room situation management data 44 in a state where main windows are opened. When this data is compared with the data of FIG. 7A, the state of main windows and the operating states of the air conditioner 14 and the ventilator 22 are changed. Each means described in FIG. 6 receives a notification of the event from the situation management data generation means 60 at the timing when the contents of the room-by-room situation management data 44 are rewritten, and refers to the rewritten contents to each of the means. Execute the process.

  FIG. 7B shows an example of the environmental data 46 for each resident. The environmental data 46 for each resident is generated for each resident by the environmental data generating means 62. Each data is distinguished by resident identification information. The comfortable room temperature and the comfortable outside air temperature are recorded by the outputs of the room temperature sensor 24 and the outside air temperature sensor 26 when each resident opens the window. It should be noted that the comfortable room temperature and the comfortable outside temperature may be optimized by learning such that acquisition is repeated and an average value is obtained.

  Furthermore, for example, it is conceivable that the comfortable room temperature differs from the comfortable outside temperature depending on the room, humidity, time when the window is opened, and the season. Therefore, for example, it is preferable to set a parameter that causes a large variation in “comfortable room temperature and comfortable outside temperature” and to store “comfortable room temperature and comfortable outside temperature” for each parameter. In the above explanation, when the outside air temperature becomes equal to the comfortable outside air temperature recorded in the environmental data 46 for each resident while using the air conditioner, a message is output to the resident to open the window. did. At this time, first, a combination of “comfortable room temperature and comfortable outside temperature” may be selected according to the parameters, and then the comfortable outside temperature may be referred to.

(Acquisition of environmental data for each resident by opening and closing windows)
FIG. 8 is an operation flowchart (part 1) of the air conditioning system according to the first embodiment.
A specific operation of the system having the above-described configuration will be described with reference to FIGS. A description will be given of a floor plan as shown in FIG. The room 12 to be managed is provided with the facilities shown in FIG. A resident who uses the room 12 to be managed has used the air conditioner 14 so far. The opening / closing sensor 18 detects that the main window 16 of the room 12 to be managed is closed (step S11). At this time, it can be judged that the resident was comfortable in the thermal environment at least immediately before.

  Therefore, the temperature detection signal receiving unit 54 acquires the room temperature data 28 and the outside air temperature data 29 of the management target room when the main window 16 of the management target room is closed (steps S12 and S13). When the window is closed, the operation of the ventilator 22 that controls the ventilation of the window is stopped (step S14). The environmental data generating means 62 generates the resident-specific environmental data 46 including the resident identification information, the room temperature and the outside air temperature of the room to be managed, and stores the data in the storage device 42 (steps S15, S16, S16). 1). The room temperature and the outside temperature recorded in the resident environment data 46 are information indicating the comfortable environment of the resident in the room to be managed. Since the resident identification information is recorded in the room-by-room situation management data 44, it is referred to (steps S15 and S16).

(Message output recommending window opening)
FIG. 9 is an operation flowchart (No. 2) of the air conditioning system according to the first embodiment.
After the main window 16 of the room to be managed is closed, the air conditioning operation control means 56 initializes the air conditioner 14 so that the room temperature and humidity of the room to be managed are maintained as they are. You can also start driving automatically. As already described with reference to FIGS. 4 and 5, normally, after the window is closed, the outside air temperature rises and the room temperature slightly decreases due to the operation of the air conditioner 14. After that, when the outside air temperature decreases due to the passage of time or weather, and reaches a value that is comfortable for the resident, if the window is opened and ventilation is performed, the room temperature also becomes the value that is welcoming for the resident. It becomes possible to hold.

  Therefore, when the temperature detection signal receiving unit 54 rewrites the room temperature data 28 and the outside air temperature data 29 of the storage device 42, the event is notified to the situation management data generation unit 60. The status management data generation means 60 rewrites the room status management data 44 each time. Then, when the room situation management data 44 is rewritten, the event is notified to the message output means 66. The room temperature management data 44 is referred to (step S21), and the outside air temperatures are compared. (Step S22). When the outside air temperature drops and the outside air temperature outside the room to be managed reaches a value that is the comfortable environment for the resident, the message output means 66 sends a message “ A message indicating that it is recommended to open the window is output (steps S23, 24, and 25). The message is output as text or image data to the display 32 through the screen control means 64. Also, audio data is output to the speaker 34.

  Thereby, the resident opens the window. When the window opening / closing signal receiving means 52 acquires the opening / closing signal 20 of the opening / closing sensor 18, the event is notified to the air conditioning operation control means 56 and the ventilator operation control means 58 (step S26). Under the control of the air conditioning operation control means 56, the air conditioner 14 automatically stops operating (step S27). At the same time, the room temperature of the room to be managed is monitored, and the ventilator 22 is operated so that the room temperature can maintain a value that is a comfortable environment for the occupants (step S28). This control is executed by the ventilator operation control means 58. In order to prevent an increase in room temperature due to insufficient ventilation, it is preferable to operate the ventilator as necessary. As will be described later, it is preferable to provide a ventilation amount adjustment button on the terminal device 70 of the resident so that the resident can adjust the ventilation amount.

(Learning effect)
As described above, by detecting the act of the occupant closing the window, it can be determined that the occupant has obtained a comfortable environment without an air conditioner. Assume that the occupant's comfortable environment is a value such as the outside air temperature or room temperature acquired when the window is closed. Thereby, when outside temperature falls, a message can be transmitted so that a resident may open a window.

  When the main window is closed and the air conditioner is operating, the resident is often unaware of changes in the outside temperature. Therefore, as described above, it is most preferable that the air conditioning system monitors the room temperature and the outside temperature of the room to be managed and outputs a message recommending opening of the window. However, residents themselves may open windows and take in outside air. Then, when the state with the window opened continues, it can be determined that the room temperature and the outside temperature at that time are comfortable for the resident.

  For example, it is assumed that the room temperature of 28 degrees when the resident closes the window in summer is learned as the optimum set temperature. Here, when the resident spontaneously opens the window and takes in outside air, if the room temperature is 29 degrees, it can be determined that the resident feels comfortable even at this temperature. In that case, it is preferable to rewrite the environmental data for each resident so that the optimum set temperature is 29 degrees Celsius. Then, if the room temperature when the resident closes the window is 30 degrees, it can be determined that 30 degrees is uncomfortable and 29 degrees is comfortable. It is good to learn by repeating acquisition of data in this way, and to determine the optimal preset temperature for every resident.

  If the same occupant acquires both data when the main window is opened and when the main window is closed and the air conditioner is activated, the upper and lower limits of the temperature range that the resident feels comfortable with The data indicating that is acquired. For example, when a main window is opened in summer, it can be determined that a comfortable temperature (lower limit) for the occupant is obtained by ventilation. After a while, when the main window was closed and the air conditioner was started, the room temperature increased with the rise of the outside temperature, and the resident reached the limit temperature (upper limit) requiring air conditioning. It can be judged. Therefore, when the above-mentioned environment selection data for each resident is repeatedly acquired and the average value is calculated, a learning operation for obtaining the upper limit value and the lower limit value of the temperature range that the resident feels comfortable can be performed.

(Ventilation effect)
FIG. 10 is an explanatory diagram of the ventilation effect.
When the above control is performed, if all the main windows are not opened and closed, the ventilation effect and the air conditioning effect will be hindered. Therefore, for example, as shown in FIG. 10A, the ventilator operation control means 58 determines whether or not all the main windows are closed (steps S31 and S32) and forgets to close them. The detected window is detected (step S33), and a message to that effect may be output (step S34).

  Further, as shown in FIG. 10B, when the main windows are opened, it is determined whether or not all the windows are opened (steps S41 and S42), and the windows that are forgotten to be opened are detected (step S43). A message to that effect may be output (step S44).

  Further, as shown in FIG. 10 (c), when the main window of the room to be managed is opened, the outside air temperature and the opening degree of the main window are detected (steps S51 and S52), and the necessary ventilation is determined. It is preferable to calculate and control the air volume of the ventilation device 22 (steps S53 and S54). For example, when the resident fully opens the main window, a comfortable environment can be obtained only by natural ventilation, and indoor ventilation is sufficient, so there is no need to operate the ventilator 22. On the other hand, if the resident detects that the main window has been opened by half, for example, the amount of ventilation that is insufficient relative to the designed amount of ventilation is compared with the amount of ventilation when fully opened. The ventilator 22 may be operated to compensate. On the other hand, for example, there is a case where natural ventilation is insufficient even when the main window is completely opened in a windless state. In order to deal with this, when the room temperature is detected and the temperature difference from the outside air temperature becomes larger than a certain level, the ventilator 22 may be operated so as to reduce the temperature difference.

  Moreover, it is preferable that the air conditioner 14 controls the room temperature of the value which is a comfortable environment of the resident recorded in the resident environment data 46 as a standard value. At this time, it accepts the input of information indicating the type of clothes to the resident, status information such as sleeping or cooking, and information indicating the characteristics of the resident such as the elderly, and automatically sets the air conditioner from the standard value. You may perform control to shift to. For example, it accepts the input of information indicating the type of clothing such as warm biz, cool biz, etc., and the input of information indicating characteristics of residents such as characteristics of the elderly and infants, age and gender, and the setting of the air conditioner from the standard value Control for shifting may be executed. For example, even if the resident is the same, when the type of clothing is designated as either “warm” or “cool”, the control may be performed at a point that is raised or lowered once from the optimum set temperature.

  Furthermore, by setting a certain range from the standard value as the fluctuation range and executing fluctuation control for changing the temperature at an arbitrary period, energy saving control as a whole is possible. For example, when the optimum set temperature is set to 28 degrees from the environmental data for each resident and this is set as a reference value, for example, when the set temperature is slowly raised or lowered at a cycle of 10 minutes or 1 hour in the range of 30 degrees to 27 degrees. Good.

(Resident control terminal)
Only certain residents may use the room to be managed. On the other hand, there is a case where a room to be managed is used in which different residents are changed. Several residents may use it at the same time. At this time, each resident has an individual difference in the sensible temperature. In the system of this embodiment, a control method suitable for these cases will be described.

FIG. 11 is an explanatory diagram of an entry / exit management apparatus using the display 32 shown in FIG.
In this embodiment, a means for recognizing at least a resident who closes a main window of a room to be managed is provided unless the room to be managed is used only by a specific resident. This is because the resident environment data 46 for each resident is generated. To recognize which resident is in the room to be managed, a known entrance / exit management device can be used. For example, each resident may have an IC tag and automatically detect entry / exit. In this embodiment, entry / exit management is performed more easily using the display 32.

  In FIG. 11, four residents are registered in advance on the display 32. Then, as shown in the figure, when the resident enters or exits, the resident is pushed a registration button 72. When any of the registration buttons 72 is pushed, the status management data generating unit 60 is notified through the communication device 35 and the communication control unit 67 of the identification information of the corresponding resident and the information on whether the user is in the room. The situation management data generating means 60 rewrites the room-by-room situation management data 44 every time a resident enters and leaves. Then, when the corresponding resident closes the main window, the environmental data generation unit 62 acquires the identification information of the resident and generates the resident-specific environmental data 46.

  The registration button 72 may be a touch switch using a display. When the information of the ID card or tag possessed by the resident is read, the process of automatically pushing the registration button 72 is executed. When there are a plurality of residents in the room to be managed, a message for opening a window may be output by referring only to the environment data 46 of each specific resident. However, the air-conditioning operation control means 56 can also control the air-conditioning apparatus 14 on the basis of the value of the outside air temperature of the resident-specific environment data 46 of a plurality of residents and using that value as a reference. The message output means 66 may output a message for opening a window based on the value.

(Control terminal for each resident)
FIG. 12 is an explanatory diagram of a control terminal for identifying individual residents.
According to a known technique, the resident 68 can control the air conditioner 14 by an application program of a mobile phone. This mobile phone will be called a control terminal 70. In this embodiment, for example, all the residents 68 have the control terminal 70 of the air conditioner 14. If each resident can communicate with the air conditioning control device 36 using the control terminal 70, the air conditioning control device 36 can easily distinguish the resident and perform the above control.

  For example, when the resident 68 closes the window, the probability that the resident 68 activates the air conditioner 14 is high. Accordingly, the air conditioning control device recognizes which resident 68 has activated the air conditioning device 14. The control terminal 70 is preferably provided with a function of performing on / off control of the air conditioner 14 and a function of setting a temperature. Furthermore, as shown in FIG. 12 (b), it is preferable to have a function of displaying a message transmitted from the message output means 66 of the air conditioning control device to the corresponding occupant with characters, images, and sounds. This can be realized if the control terminal 70 is a mobile phone.

  When a common control terminal is used, a button or the like for notifying the operator when operating the control terminal may be provided on the control terminal. The temperature setting of the air conditioner can be freely adjusted by the resident. However, for example, as shown in FIG. 12 (c), the control button is only controlled to “increase temperature” and “decrease temperature”. For example, the temperature changes once every time the button is pressed. The configuration is as follows. This is because when the temperature that the occupant actually feels is optimized, the temperature display indicating the numerical value is not preferable. The same applies to the amount of ventilation.

  The air conditioning control device has already learned the settings that the resident feels comfortable. Therefore, the optimum setting can usually be made automatically. However, when the resident frequently performs the control of “increasing the temperature” or “decreasing the temperature”, the learning result is corrected. For example, when air conditioning has been started with the optimum setting value of 28 degrees, when the resident presses the “decrease temperature” button once, 27 degrees may be corrected to the lowest setting value.

  In the above system, the occupant opens and closes the window as he / she feels, and the room temperature controller monitors the operation and obtains environment selection data for each occupant, thus requiring cumbersome operations such as data registration and setting. And not. Each room in the building can be opened and closed at the optimal timing for each resident, creating a thermal environment that makes full use of ventilation. Therefore, there is an extremely high energy saving effect. In addition, it is said that the thermal environment using ventilation is optimal for the health of residents. If the resident has a habit of actively incorporating this environment, there is an effect that the time that does not depend on the air conditioner is increased more than before.

  Note that the computer program executed by the arithmetic processing unit may be modularized in units illustrated in functional blocks, or may be integrated by combining a plurality of functional blocks. Further, the above computer program may be used by being incorporated into an existing application program. The computer program for realizing the present invention can be recorded on a computer-readable recording medium such as a CD-ROM and installed in any information processing apparatus for use.
