Summary of the Invention

Problems to be Solved by the Invention

[0004] In a conventional air conditioning system, a ventilation duct communicates from a space where a heating device is installed to a space where it is not installed, and a duct fan provided in the ventilation duct sends warm air from the heating device to send warm air to the space where it is not installed.

[0005] However, when the duct fan sends warm air from the space where the heating device is installed to the space where it is not installed, the space where it is not installed warms from the upper part and gradually moves downward. The user wants to warm their feet, that is, the lower part of the space, and there is a problem that it takes time for the lower part of the space to warm up.

[0006] The present disclosure has been made to solve the above problems, and by providing an opening / closing device in a communication part that communicates the lower part of the space where the air conditioner is installed and the lower part of the space where it is not installed, an air conditioning system that sends warm air or cold air to the lower part of the space where it is not installed and improves comfort is obtained.

Means for Solving the Problems

In addition, a first temperature sensor is installed in the first space and a second temperature sensor is installed in the second space. The communication unit acquires the set temperature of the air conditioner, the first measured temperature of the first temperature sensor, and the second measured temperature of the second temperature sensor. When the absolute value of the difference between the set temperature and the first measured temperature is within the range of the first threshold, and the absolute value of the difference between the first measured temperature and the second measured temperature exceeds the second threshold, the control unit performs control to open the switchgear. [Effects of the Invention]

Modes for Carrying Out the Invention

[0010] Embodiment 1. FIG. 1 is a configuration diagram showing an air conditioning system 1 of Embodiment 1. The air conditioning system 1 includes an air conditioner 11, a first temperature sensor 31, a second temperature sensor 32, an opening / closing device 51, a control device 61, and a control panel 71. Further, the air conditioning system 1 is in a building. The building has a first space 21 and a second space 22. Although not shown, the building is a building, a house, etc.

[0011] The control device 61 includes a communication unit 62 and a control unit 63. The communication unit 62 is communicably connected to the air conditioner 11, the first temperature sensor 31, the second temperature sensor 32, and the control panel 71.

[0012] The air conditioner 11 adjusts the temperature and humidity and blows air in the first space 21. For example, the air conditioner 11 is an air conditioner. The user of the air conditioner 11 sets the temperature, humidity, etc. by operating the control panel 71. When the user sets cooling or heating, the air conditioner 11 starts cooling or heating the first space 21 and the second space 22. Alternatively, the control unit 63 may set the temperature, humidity, etc., and the communication unit 62 may transmit the set temperature, set humidity, etc. to the air conditioner 11.

[0013] The operation between the control panel 71, the air conditioner 11, and the communication unit 62 is as follows: For example, the user sets the cooling temperature on the control panel 71. Next, the control panel 71 transmits the cooling temperature to the air conditioner 11, and the air conditioner 11 receives the cooling temperature. Upon receiving the temperature, the air conditioner 11 sets the temperature and begins the cooling operation to reach that temperature. Subsequently, the communication unit 62 transmits a request for the set temperature to the air conditioner 11. The air conditioner 11 receives the request for the set temperature. Upon receiving the request, the air conditioner 11 reads the already set cooling temperature and transmits a response of the set temperature to the communication unit 62. The communication unit 62 receives the response of the set temperature.

[0014] Partition 12 divides a space within a building into multiple sections. The partition 12 shown in Figure 1 separates the first space 21 from the second space 22. There are no restrictions on the material or thickness of the partition 12. For example, the partition 12 can be a wall, a divider, a sliding door, a shoji screen, etc.

[0015] The first space 21 is a single space where an air conditioner 11 is installed, separated by, for example, side walls, windows, ceiling, floor, doors, and partitions 12. The first space 21 is, for example, a living room.

[0016] The second space 22 is a single space where the air conditioner 11 is not installed, separated by, for example, side walls, windows, ceiling, floor, doors, and partitions 12. The second space 22 is connected to the first space 21 by a connecting section 41. The second space 22 may include, for example, a dressing room, a pantry, or an entrance hall.

[0017] At least one of the first space 21 and the second space 22 is preferably composed of highly insulated side walls, windows, ceilings, floors, doors, etc. However, a configuration that is not highly insulated is also acceptable.

[0018] The first temperature sensor 31 measures the temperature of the first space 21. The temperature measured in the first space 21 is called the first measured temperature. In the operation between the first temperature sensor 31 and the communication unit 62, for example, the communication unit 62 sends a request for the first measured temperature to the temperature sensor 31. Next, the temperature sensor 31 receives the request. After that, the temperature sensor 31 sends a response of the measured first measured temperature to the communication unit 62. The communication unit 62 receives the response of the first measured temperature sent from the temperature sensor 31.

[0019] The second temperature sensor 32 measures the temperature of the second space 22. The operation between the second temperature sensor 32 and the communication unit 62 is similar to the operation between the first temperature sensor 31 and the communication unit 62.

[0020] Examples of the types of first temperature sensors 31 and second temperature sensors 32 include IC temperature sensors, thermocouples, thermistors, and infrared non-contact temperature sensors. The first temperature sensor 31 and second temperature sensor 32 may be different types of temperature sensors. The first temperature sensor 31 may be built into the air conditioner 11.

[0021] The connecting section 41 connects the first space 21 and the second space 22, which are separated by the partition 12. For example, the type of connecting section 41 is a hole in the partition 12, a duct, a sleeve, etc. It is desirable that the connecting section 41 be in contact with the floor. At the very least, it should be in the lower part of the partition 12.

[0022] The opening / closing device 51 is installed in the communication section 41. The type of opening / closing device 51 is an electrically operated shutter, an electrically operated valve, etc. The operation between the opening / closing device 51 and the communication unit 62 is as follows: For example, the communication unit 62 sends a request to open the opening / closing device 51. When the opening / closing device 51 receives the request to open, it starts the opening operation. After completing the opening operation, the opening / closing device 51 sends an open response to the communication unit 62. The communication unit 62 receives the open response from the opening / closing device 51.

[0023] The opening / closing device 51 has an opening (not shown) through which cold or warm air passes from the first space 21 to the second space 22. For example, this is an opening through which cold or warm air passes when an electrically operated shutter or the like is opened. It is desirable that this opening has a large surface area.

[0024] Figure 2 is a diagram showing the configuration of the control device 61 in the air conditioning system 1.

[0025] The communication unit 62 is connected to the air conditioner 11, the first temperature sensor 31, the second temperature sensor 32, the switchgear 51, and the control panel 71 in a communication-enabled manner. Specific types of communication include wired communication such as Ethernet®, and wireless communication such as Wi-Fi®, Bluetooth®, and infrared communication. The communication unit 62 communicates using components such as connectors for wired communication and antennas for wireless communication. Figure 2 shows an example of an antenna as the communication component.

[0026] For example, in communication between the control unit 63, the communication unit 62, and the second temperature sensor 32, the communication unit 62 receives a request from the control unit 63 for the measurement temperature of the second space 22, and the communication unit 62 transmits the request to the second temperature sensor 32. The second temperature sensor 32 then transmits a response for the second measurement temperature, and the communication unit 62 receives the response for the second measurement temperature. The communication unit 62 transmits the response for the measurement temperature of the second space 22 to the control unit 63, and the control unit 63 obtains the response for the measurement temperature of the second space 22.

[0027] The control unit 63 transmits a request to the communication unit 62. The receiving communication unit 62 transmits the request to one of the following devices: the air conditioner 11, the first temperature sensor 31, the second temperature sensor 32, the switchgear 51, or the control panel 71. The receiving device transmits a response to the communication unit 62. The control unit 63 receives the response from the communication unit 62.

[0028] The functions of the communication unit 62 and the control unit 63 can be realized by a processing circuit. For example, the processing circuit includes at least one processor 100a and at least one memory 100b. For example, the processing circuit includes at least one dedicated hardware 200.

[0029] When the processing circuit comprises at least one processor 100a and at least one memory 100b, the functions of the communication unit 62 and the control unit 63 are realized by software, firmware, or a combination of software and firmware. At least one of the software and firmware is written as a program. At least one of the software and firmware is stored in at least one memory 100b. The at least one processor 100a realizes the functions of the communication unit 62 and the control unit 63 by reading and executing the program stored in at least one memory 100b. The at least one processor 100a is also called a central processing unit, processing unit, arithmetic unit, microprocessor, microcomputer, or DSP. For example, the at least one memory 100b is a non-volatile or volatile semiconductor memory such as RAM, ROM, flash memory, EPROM, EEPROM, magnetic disk, flexible disk, optical disk, compact disk, minidisc, DVD, etc.

[0030] If the processing circuit includes at least one dedicated hardware 200, the processing circuit may be implemented as, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof. For example, the functions of the communication unit 62 and the control unit 63 may each be implemented in the processing circuit. For example, the functions of the communication unit 62 and the control unit 63 may be implemented together in the processing circuit.

[0031] Some functions of the communication unit 62 and the control unit 63 may be implemented using dedicated hardware 200, while others may be implemented using software or firmware. For example, the function of controlling the air conditioner 11 may be implemented using a processing circuit as dedicated hardware 200, while functions other than controlling the air conditioner 11 may be implemented by at least one processor 100a reading and executing a program stored in at least one memory 100b.

[0032] In this way, the processing circuit realizes the functions of the communication unit 62 and the control unit 63 through hardware 200, software, firmware, or a combination thereof.

[0033] As a prerequisite for control, the memory 100b of the control unit 63 stores a first threshold and a second threshold in advance. The first threshold is the value at which it is determined that the first measured temperature is approaching the set temperature. The second threshold is the value at which it is determined that the first measured temperature and the second measured temperature are far apart.

[0034] The control panel 71 is a device for displaying the status of the first space 21 and the second space 22 and for operating them. For example, it may be a display such as a 7-segment LED, liquid crystal, or OLED (Organic Light Emitting Diode) to indicate the status, or a user interface (UI) such as a touch panel, buttons, or numeric keypad for operation by the user. The control panel is not limited to the control panel 71 shown in Figure 1; for example, a tablet, smartphone, or remote controller may be used, wirelessly connected to at least one of the air conditioner 11 and the communication unit 62, allowing the user to operate cooling, heating, etc., and set the temperature, humidity, etc.

[0035] Figure 3 is an operation diagram of the air conditioning system 1 shown in Embodiment 1.

[0036] In the following descriptions of the operations of Embodiments 1 to 4, the operation of internal communication of the control device 61, that is, communication between the control unit 63 and the communication unit 62, will be omitted for the sake of brevity. Hereafter, "the communication unit 62 sends a request" means "the control unit 63 sends a request to the communication unit 62, and the communication unit 62 receives the request. Next, the communication unit 62 sends a request." Similarly, "the communication unit 62 receives a response" means "the communication unit 62 receives a response, and the communication unit 62 sends a response to the control unit 63. Next, the control unit 63 receives the response."

[0037] In step C1, the communication unit 62 sends a request to the air conditioner 11 to read the operating status of the air conditioner 11, and the communication unit 62 receives a response from the air conditioner 11 regarding the operating status. The control unit 63 determines whether the operating status is ON. The operating state of the air conditioner 11 refers to the state in which the air conditioner 11 is operating (ON) or in which it is stopped (OFF). For example, the stopped (OFF) state can be changed to the operating (ON) state by a user using a remote controller or the like. In other words, power is still supplied even when the unit is stopped (OFF). If the operating state is not ON, the control unit 63 proceeds to the next determination (step C9). When the operating state is ON, the control unit 63 proceeds to the next determination (step C2).

[0038] In step C2, the communication unit 62 sends a request to read the cooling and heating status of the air conditioner 11 and receives a response regarding the cooling and heating status of the air conditioner 11. The control unit 63 determines whether the cooling or heating is ON. Note that "cooling status" refers to the state where the air conditioning is ON or OFF. Similarly, "heating status" refers to the state where the heating is ON or OFF. When neither the cooling nor the heating is ON, the control unit 63 proceeds to the next operation (step C7). When the cooling or heating function is ON, the control unit 63 performs the following operation (step C3).

[0039] In step C3, the temperature set in the air conditioner 11 is called the set temperature. The communication unit 62 sends a request for this set temperature to the air conditioner 11. When the air conditioner 11 receives the request for the set temperature, it reads the set temperature. The air conditioner 11 sends a response of the read set temperature to the communication unit 62. The communication unit 62 receives the response of the set temperature sent from the air conditioner 11. Similarly, the temperature measured by the first temperature sensor 31 is called the first measured temperature. The communication unit 62 sends a request for this first measured temperature to the first temperature sensor 31. When the first temperature sensor 31 receives the request for the first measured temperature, it measures the temperature. Once the first temperature sensor 31 has finished measuring the temperature, it sends a response of the measured first measured temperature to the communication unit 62. The communication unit 62 receives the response of the first measured temperature sent from the first temperature sensor 31. Similarly, the temperature measured by the second temperature sensor 32 is called the second measured temperature. The communication unit 62 sends a request for this second measured temperature to the second temperature sensor 32. When the second temperature sensor 32 receives the request for the second measured temperature, it measures the temperature. Once the second temperature sensor 32 has finished measuring the temperature, it sends a response of the measured second measured temperature to the communication unit 62. The communication unit 62 receives the response of the second measured temperature sent from the second temperature sensor 32. In this way, the control unit 63 acquires the set temperature of the air conditioner 11, the first measured temperature of the first temperature sensor 31, and the second measured temperature of the second temperature sensor 32. Hereafter, examples of cooling and heating in Embodiment 1 will be shown step by step.

[0040] In the example of air conditioning in step C3, the temperature set by the user for air conditioning is 26°C, the temperature measured by the first temperature sensor 31 is 34°C, the temperature measured by the second temperature sensor 32 is 35°C, the predetermined first threshold is 1°C, and the predetermined second threshold is 1°C.

[0041] Figure 4 shows an example of the cooling function of the control panel 71 during step C3, which is part of Embodiment 1.

[0042] The types of operation buttons shown in Figure 4 are common to both the first space 21 and the second space 22: a "cooling" button, a "heating" button, a "▲" button to increase the set temperature, a "▼" button to decrease the set temperature, a "humidity control" button, a "▲" button to increase the set humidity, and a "▼" button to decrease the set humidity. In addition, there are buttons that operate only the second space 22: a second space "off" button 81, a "timer" button 82, a "top" button 83, and a "human motion sensor" button 84. The types of displays shown in Figure 4 are the first space 21, the air conditioner 11, the switchgear 51, the second space 22, the set temperature value, the first measured temperature value, and the second measured temperature value. In Figure 4, the set humidity, the measured humidity of the first space 21, the measured humidity of the second space 22, and the timer time are not displayed because they have not been set or measured.

[0043] In the cooling example of step C3, the set temperature is 26°C, the first measured temperature is 34°C, and the second measured temperature is 35°C, and these values ​​are displayed on the control panel 71 in Figure 4. On the other hand, the "Cooling" button, the "▲" button to increase the set temperature, and the "▼" button to decrease the set temperature are all operational. Operational buttons are displayed with a white background. The other "heating" button is disabled. Disabled buttons are displayed with a black background. The second space "off" button 81 is disabled, so its background is displayed with a black background. Furthermore, the opening / closing device 51 is in the closed state, and the background color indicating the opening / closing device 51 is displayed in black.

[0044] In the heating example in step C3, the temperature set by the user for heating is 18°C, the temperature measured by the first temperature sensor 31 is 7°C, the temperature measured by the second temperature sensor 32 is 5°C, the predetermined first threshold is 1°C, and the predetermined second threshold is 1°C.

[0045] In step C4, the difference between the set temperature and the first measured temperature is called the set temperature difference. The control unit 63 calculates the absolute value of the set temperature difference. It then determines whether the calculated absolute value of the set temperature difference is less than or equal to the first threshold. If the value is not below the first threshold, the control unit 63 performs the following operation (step C7). If the value is below the first threshold, the control unit 63 proceeds to the next determination (step C5).

[0046] In the example of air conditioning in step C4, if the set temperature is 26°C and the first measured temperature is 34°C, proceed to step C7. On the other hand, if the set temperature is 26°C and the first measured temperature is 27°C, the absolute value of the set temperature difference is 1°C, which satisfies the first threshold of 1°C or less, so proceed to step C5.

[0047] In the heating example in step C4, when the set temperature is 18°C ​​and the first measured temperature is 7°C, the process proceeds to step C7. On the other hand, when the set temperature is 18°C ​​and the first measured temperature is 17°C, the absolute value of the set temperature difference is 1°C, which satisfies the first threshold of 1°C or less, so the process proceeds to step C5.

[0048] In step C5, the difference between the first measured temperature and the second measured temperature is called the ambient temperature difference. The control unit 63 calculates the absolute value of the ambient temperature difference. It then determines whether the calculated absolute value of the ambient temperature difference exceeds the second threshold. If the second threshold is not exceeded, the control unit 63 performs the following operation (step C7). When the second threshold is exceeded, the control unit 63 performs the following operation (step C6).

[0049] In the air conditioning example in step C5, when the first measured temperature is 26°C and the second measured temperature is 35°C, the absolute value of the difference is 9°C, which exceeds the second threshold of 1°C, so step C6 is executed. On the other hand, when the first measured temperature is 26°C and the second measured temperature is 27°C, the absolute value of the ambient temperature difference is 1°C, which does not exceed the second threshold of 1°C, so step C7 is executed.

[0050] In the heating example in step C5, when the first measured temperature is 17°C and the second measured temperature is 5°C, the absolute value of the difference is 12°C, which exceeds the second threshold of 1°C, so step C6 is executed. On the other hand, when the first measured temperature is 17°C and the second measured temperature is 16°C, the absolute value of the ambient temperature difference is 1°C, which does not exceed the second threshold of 1°C, so step C7 is executed.

[0051] In step C6, the communication unit 62 sends an open request to the switchgear 51, and the switchgear 51 receives the open request. If the switchgear 51 is already open, it maintains that state and the process is completed. If the switchgear 51 is not open, it performs an opening operation and completes the opening operation. After that, the switchgear 51 sends an open response to the communication unit 62, and the communication unit 62 receives the response that the switchgear 51 has opened. When the opening / closing device 51 opens, cold or warm air at the temperature of the first space 21 enters the second space 22. The cold or warm air that enters mixes due to thermal equilibrium, and the temperature of the second space 22 approaches the temperature of the first space 21. In particular, if the opening / closing device 51 is aligned with the floor surface, the temperature of the first space 21 can easily enter the floor of the second space 22, i.e., the floor surface of the second space 22.

[0052] Figure 5 shows an example of cooling on the control panel 71 during step C6 of Embodiment 1. From Figure 5 onward, for the sake of clarity in the explanation, the control panel 71 will be shown with the buttons operated or the values ​​displayed in Figure 4. The switchgear 51 is in the open state, and the background color indicating the switchgear 51 is shown as white. Cold air enters the second space 22 from the first space 21, and the mixing of the air that entered the second space 22 and the air in the second space 22 due to thermal equilibrium is represented by arrow 91. Note that the arrow 91 representing the mixing of air in the second space 22 is not limited to the one shown; any shape of arrow representing the mixing of air is acceptable.

[0053] After the control unit 63 has performed step C6, the control unit 63 performs the next operation (step C8). After the control unit 63 has performed step C7, the control unit 63 performs the next operation (step C8).

[0054] In step C7, the communication unit 62 sends a closing request to the switchgear 51, and the switchgear 51 receives the closing request. If the switchgear 51 is already closed, it maintains that state and the process is completed. If the switchgear 51 is not already closed, it performs the closing operation and completes the closing operation. After that, the switchgear 51 sends a closed response to the communication unit 62, and the communication unit 62 receives the closed response from the switchgear 51. After performing step C7, the control unit 63 performs the next operation (step C8).

[0055] In step C8, the communication unit 62 sends a request for the specified waiting time T to the control panel 71. The control panel 71 receives the request for the specified waiting time T. Upon receiving the request, the control panel 71 reads the set waiting time T and sends a response to the communication unit 62 for the set waiting time T. The communication unit 62 receives the set waiting time T. The control unit 63 counts down the timer according to the set waiting time T. For example, when the waiting time T is set to 5 minutes, the timer time display 85 on the control panel 71 displays 5 minutes and waits until it is reduced from 5 minutes to 0 seconds. Also, when the timer starts counting down, the second space of the control panel 71 "OFF" The background color of button 81 changes from black to white. In other words, when the user presses the second space "Off" button 81... It becomes operable. When the user operates the second space "Off" button 81, the waiting time T is forcibly ended. It becomes 0 seconds. After the waiting time T has elapsed, the timer display 85 on the control panel 71 will show 0 seconds. The control unit 63 then proceeds to the next determination (step C9).

[0056] In step C9, the state in which the user has operated the "Off" button 81 for the second space to turn off the cooling and heating of the second space 22 is called the second space air conditioning OFF state. The communication unit 62 sends a request for the second space air conditioning OFF state to the control panel 71, and the control panel 71 receives the request for the second space air conditioning OFF state. The control panel 71 reads the second space air conditioning OFF state and sends a response of the second space air conditioning OFF state to the communication unit 62. The control unit 63 determines whether the cooling and heating of the second space 22 is OFF. If the cooling and heating in the second space 22 are not in the OFF state, the control unit 63 proceeds to the next determination (step C1). When the cooling and heating in the second space 22 are turned OFF, the control unit 63 performs the following operation (step C10).

[0057] In step C10, the communication unit 62 sends a closing request to the switchgear 51, and the switchgear 51 receives the closing request. If the switchgear 51 that received the request is already closed, it maintains that state and the process is completed. If the switchgear 51 that received the request is not already closed, it performs the closing operation and completes the closing operation. After that, the switchgear 51 sends a closed response to the communication unit 62, and the communication unit 62 receives the closed response from the switchgear 51. The user has turned off the air conditioning and heating in the second space 22, so the operation is complete.

[0058] Figure 6 shows an example of the air conditioning on the control panel 71 during step C10, which represents Embodiment 1. When the user operates the "Off" button 81 for the second space, the second space air conditioning is turned OFF, and steps C9 to C10 are executed, causing the opening / closing device 51 to close. As a result, the opening / closing device 51 is in a closed state. Therefore, the background color indicating the opening / closing device 51 is changed to black.

[0059] If the user does not turn off the cooling or heating in the second space 22, steps C1 to C9 are repeated, and eventually the first threshold in step C4 is met and the second threshold in step C5 is not met. In other words, the process proceeds to step C7, and the cooling or heating in the second space 22 is temporarily terminated.

[0060] In the example of cooling the second space 22, when the set temperature is 26°C and the first measured temperature is 27°C, the absolute value of the spatial temperature difference is 1°C, which is below the first threshold of 1°C, so the process proceeds from step C4 to step C5. When the first measured temperature is 27°C and the second measured temperature is 27°C, the absolute value of the spatial temperature difference is 0°C, which does not exceed the second threshold of 1°C, so the process proceeds from step C5 to step C7, and the cooling of the second space 22 is temporarily terminated.

[0061] In the example of heating the second space 22, when the set temperature is 18°C ​​and the first measured temperature is 18°C, the absolute value of the spatial temperature difference is 0°C, which is less than or equal to the first threshold of 1°C, so the process proceeds from step 4 to step C5. When the first measured temperature is 18°C ​​and the second measured temperature is 17°C, the absolute value of the spatial temperature difference is 1°C, which does not exceed the second threshold of 1°C, so the process proceeds from step C5 to step C7, and the heating of the second space 22 is temporarily terminated.

[0062] Furthermore, even after the cooling or heating of the second space 22 has been temporarily stopped, the control unit 63 continues to operate repeatedly from step C1 to step C9 based on changes in the first and second measured temperatures.

[0063] As described above, the air conditioner 11 and the first temperature sensor 31 are installed in the first space 21, and the second temperature sensor 32 is installed in the second space 22. Furthermore, an opening / closing device 51 is installed in a connecting section 41 that connects the lower part of the first space 21 and the lower part of the second space 22. The communication unit 62 acquires the set temperature of the air conditioner 11, the first measured temperature of the first temperature sensor 31, and the second measured temperature of the second temperature sensor 32. When the control unit 63 calculates the absolute value of the difference between the set temperature and the first measured temperature and determines that it is within the range of the first threshold, and also calculates the absolute value of the difference between the first measured temperature and the second measured temperature and determines that it exceeds the second threshold, the opening / closing device 51 is opened to send warm or cool air from the first space 21 to the second space 22, thereby improving the comfort of the user.

[0064] Embodiment 2. Figure 7 is a diagram showing the configuration of the air conditioning system 1 in Embodiment 2. Embodiment 2 omits details similar to those in Embodiment 1 and describes a different configuration.

[0065] The second connecting section 42 connects the first space 21 and the second space 22, which are separated by the partition 12. While the connecting section 41 is located at the bottom of the partition 12, the second connecting section 42 is located at the top of the partition 12. For example, the type of the second connecting section 42 may be a hole in the partition 12, a duct, a sleeve, etc. The type of the second connecting section 42 may be different from the type of connecting section 41.

[0066] The second switchgear 52 is installed in the second communication section 42. The type of the second switchgear 52 may be an electric shutter, an electric valve, etc. The type of the second switchgear 52 may be different from the type of switchgear 51. The operation between the second switchgear 52 and the communication section 62 is the same as the operation between the switchgear 51 and the communication section 62.

[0067] The first fan 53 is installed in the communication unit 41. For example, the first fan 53 can be an axial fan, a duct fan, a centrifugal fan, a bidirectional fan, etc. The operation between the first fan 53 and the communication unit 62 is as follows: For example, the communication unit 62 sends a request to the first fan 53 to blow air into the second space 22. When the first fan 53 receives the request to blow air into the second space 22, it starts blowing air from the first space 21 to the second space 22. After starting to blow air into the second space 22, the first fan 53 sends a response to the communication unit 62 indicating that it is turning on the airflow to the second space 22. The communication unit 62 receives the response from the first fan 53 indicating that it is turning on the airflow to the second space 22.

[0068] The second control panel 72 is installed in the second space 22. Control panel 71 is installed in the first space 21. The functions of the second control panel 72 are the same as those of control panel 71.

[0069] Figure 8 is an operation diagram of the air conditioning system 1 shown in Embodiment 2. Here, we will explain the differences between Figure 8 and Figure 3.

[0070] In Figure 8, steps C6, C7, and C10 in Figure 3 correspond to steps C6a, C7a, and C10a, respectively. The steps other than C6a, C7a, and C10a are the same as in Figure 3.

[0071] In step C6a, the communication unit 62 sends an open request to the switchgear 51, and the switchgear 51 receives the open request. The communication unit 62 also sends an open request to the second switchgear 52, and the second switchgear 52 receives the open request. Then, the communication unit 62 sends a request to the first fan 53 to blow air into the second space 22, and the first fan 53 receives the request to blow air into the second space 22. If the received switchgear 51 is already open, the state is maintained and the process is completed. Similarly, if the received second switchgear 52 is already open, the state is maintained and the process is completed. And if the received first fan 53 is already in the ON state for blowing air into the second space 22, the state is maintained and the process is completed. If the receiving switchgear 51 is not open, it performs an opening operation and completes the opening operation. Similarly, if the receiving second switchgear 52 is not open, it performs an opening operation and completes the opening operation. Then, if the receiving first fan 53 is not blowing air into the second space 22, it starts blowing air and completes the process by turning on the airflow to the second space 22. Subsequently, the switchgear 51 transmits an open response to the communication unit 62, and the communication unit 62 receives the response that the switchgear 51 has been opened. The second switchgear 52 also transmits an open response to the communication unit 62, and the communication unit 62 receives the response that the second switchgear 52 has been opened. Then, the first fan 53 transmits a response to the communication unit 62 indicating that it is turning on the airflow to the second space 22, and the communication unit 62 receives the response from the first fan 53 indicating that it is turning on the airflow to the second space 22. When the opening / closing device 51 opens, the cold or warm air from the first space 21 is sent to the second space 22 by the first fan 53. The sent cold or warm air mixes due to thermal equilibrium and airflow, and the temperature of the second space 22 approaches the temperature of the first space 21. In particular, if the communication section 41 is along the floor surface, the temperature of the first space 21 can easily enter the floor of the second space 22, i.e., the area around the feet.

[0072] Figure 9 shows an example of cooling of control panel 71 and second control panel 72 during step C6a of Embodiment 2. The opening / closing devices 51 and 52 are in the open state, and the background color showing the opening / closing devices 51 and 52 is displayed in white. The first fan 53 blows cool air from the first space 21 to the second space 22. The cool air is blown from the first space 21 to the second space 22, and the air in the second space 22 is pushed out into the first space 21 from the top of the partition 12 by the blown cool air, as shown by arrow 92. Note that the arrow 92, which shows the air being sent from the first space 21 by the first fan 53 and exhausted from the second space 22, is not limited to the one shown, and any shape of arrow indicating airflow is acceptable.

[0073] In step C7a, the communication unit 62 sends a closing request to the switchgear 51, and the switchgear 51 receives the closing request. The communication unit 62 also sends a closing request to the second switchgear 52, and the second switchgear 52 receives the closing request. Then, the communication unit 62 sends a stop request to the first fan 53, and the first fan 53 receives the stop request. If the receiving switchgear 51 is not closed, it performs the closing operation and completes the closing operation. Similarly, if the receiving second switchgear 52 is not closed, it performs the closing operation and completes the closing operation. Finally, if the receiving first fan 53 has not stopped blowing air into the second space 22, it stops blowing air and turns the fan OFF, completing the process. Subsequently, the switchgear 51 sends a closed response to the communication unit 62, and the communication unit 62 receives the response that the switchgear 51 has been closed. The second switchgear 52 also sends a closed response to the communication unit 62, and the communication unit 62 receives the response that the second switchgear 52 has been closed. Then, the first fan 53 sends a fan-off response to the communication unit 62, and the communication unit 62 receives the fan-off response from the first fan 53. After step C7a is performed, the control unit 63 performs the next operation (step C8).

[0074] In step C10a, the communication unit 62 sends a closing request to the switchgear 51, and the switchgear 51 receives the closing request. The communication unit 62 also sends a closing request to the second switchgear 52, and the second switchgear 52 receives the closing request. Then, the communication unit 62 sends a stop request to the first fan 53, and the first fan 53 receives the stop request. If the receiving switchgear 51 is not closed, it performs the closing operation and completes the closing operation. Similarly, if the receiving second switchgear 52 is not closed, it performs the closing operation and completes the closing operation. Finally, if the receiving first fan 53 has not stopped blowing air into the second space 22, it stops blowing air and turns the fan OFF, completing the process. Subsequently, the switchgear 51 sends a closed response to the communication unit 62, and the communication unit 62 receives the response that the switchgear 51 has been closed. The second switchgear 52 also sends a closed response to the communication unit 62, and the communication unit 62 receives the response that the second switchgear 52 has been closed. Then, the first fan 53 sends a fan-off response to the communication unit 62, and the communication unit 62 receives the fan-off response from the first fan 53. The user has turned off the air conditioning and heating in the second space 22, so the operation is complete.

[0075] Thus, in addition to Embodiment 1, a first fan 53 is provided in the communication section 41, and a second opening / closing device 52 is provided in the second communication section 42 that connects the upper part of the first space 21 and the upper part of the second space 22, thereby accelerating the delivery of cool or warm air from the first space 21 to the second space 22. Consequently, user comfort can be further improved.

[0076] Figure 10 is an operation diagram of the air conditioning system 1 showing a modified example of Embodiment 2.

[0077] The configuration in Figure 7 remains unchanged, but the first fan 53 is replaced with a bidirectional fan 54.

[0078] When the second space 22 is being cooled or heated, the bidirectional fan 54 sends cool or warm air to the user's feet. Some users may dislike having air blown to their feet. If the user operates the "from above" button 83 on the second control panel 72 instead of from the feet, the bidirectional fan 54 changes its operation from blowing air to exhausting air, and cool or warm air enters from the second switchgear 52.

[0079] Let's explain the specific differences in steps between Figure 10 and Figure 8.

[0080] In step C6b, the operation of the switchgear 51 and the second switchgear 52 is the same. The operation between the communication unit 62 and the bidirectional fan 54 is different.

[0081] In step C6b, the user operates the "Top" button 83 on the UI (User Interface) of the second control panel 72. The second control panel 72 remembers that the state of the bidirectional fan 54 is exhausting rather than blowing air as a result of the operation of the "Top" button 83. The communication unit 62 sends a request to the second control panel 72 for the state of the bidirectional fan 54 (blowing or exhausting air), and the second control panel 72 receives the request for the state of the bidirectional fan 54 (blowing or exhausting air). The second control panel 72 reads the exhaust state of the bidirectional fan 54 and sends a response to the communication unit 62 indicating that the bidirectional fan 54 is exhausting air from the second space 22. The communication unit 62 receives the response indicating that the bidirectional fan 54 is exhausting air from the second space 22. As a result, the control unit 63 starts the operation to change the state of the bidirectional fan 54 from "blowing air to the second space 22" to "exhausting air from the second space 22". Next, the communication unit 62 sends a request for exhaust from the second space 22 using the bidirectional fan 54, and the bidirectional fan 54 receives the request to exhaust from the second space 22. The bidirectional fan 54 changes its operation from "blowing air to the second space 22" to "exhausting from the second space 22". In other words, the bidirectional fan 54 starts the operation of exhausting from the second space 22 and continues the operation. If it is already exhausting from the second space 22, it maintains that state. Subsequently, the bidirectional fan 54 sends an exhaust ON response from the second space 22 to the communication unit 62, and the communication unit 62 receives the exhaust ON response from the bidirectional fan 54 from the second space 22.

[0082] Figure 11 shows an example of cooling of control panel 71 and second control panel 72 during step C6b, which illustrates a modified example of Embodiment 2. The opening / closing devices 51 and 52 are in the open state, and the background color showing the opening / closing devices 51 and 52 is displayed in white. The bidirectional fan 54 exhausts the air from the second space 22 to the first space 21. The arrow 93 shows how the air from the second space 22 is exhausted to the first space 21, and how the cold air in the first space 21 enters the second space 22 from the top of the partition 12. Note that the arrow 93, which shows the air being exhausted from the second space 22 by the bidirectional fan 54 and entering from the first space 21, is not limited to the one shown, and any shape of arrow indicating airflow is acceptable.

[0083] In this way, by changing the first fan 53 to a bidirectional fan 54, the cool or warm air from the first space 21 enters from above the partition 12, thereby further improving comfort according to the preference of users who dislike having air blown towards their feet.

[0084] Embodiment 3. Figure 12 is a diagram showing the configuration of the air conditioning system 1 inside a building, representing Embodiment 3. Embodiment 3 omits details similar to those in Embodiment 2 and describes a different configuration.

[0085] The first humidity sensor 33 measures the humidity of the first space 21. The humidity measured in the first space 21 is called the first measured humidity. In the operation between the first humidity sensor 33 and the communication unit 62, for example, the communication unit 62 sends a request for the first measured humidity to the first humidity sensor 33. Next, the first humidity sensor 33 receives the request. After that, the first humidity sensor 33 sends a response of the measured first measured humidity to the communication unit 62. The communication unit 62 receives the response of the first measured humidity sent from the first humidity sensor 33.

[0086] The second humidity sensor 34 measures the humidity of the second space 22. The operation between the second humidity sensor 34 and the communication unit 62 is similar to the operation between the first humidity sensor 33 and the communication unit 62.

[0087] Examples of the types of first humidity sensors 33 and second humidity sensors 34 include capacitive humidity sensors, electrical resistance humidity sensors, wet-bulb / dry-bulb sensors, and telescopic sensors. The first humidity sensor 33 and the second humidity sensor 34 may be different types of humidity sensors. The first humidity sensor 33 may be built into the air conditioner 11.

[0088] The second fan 55 is installed in the second communication section 42. The type of the second fan 55 is the same as that of the first fan 53. The airflow direction of the second fan 55 is to exhaust air from the second space 22. Conversely, the airflow direction of the first fan 53 is to blow air into the second space 22. In this way, air from the first space 21 is sent from below the partition 12, and air from the second space 22 is exhausted from above the partition 12.

[0089] The operation between the second fan 55 and the communication unit 62 is as follows: The communication unit 62 sends a request for the second fan 55 to exhaust air from the second space 22. Upon receiving the request for the second fan 55 to exhaust air from the second space 22, the second fan 55 begins to exhaust air from the second space 22 to the first space 21. After starting to exhaust air from the second space 22, the second fan 55 sends a response to the communication unit 62 indicating that exhaust air from the second space 22 is ON. The communication unit 62 receives the response from the second fan 55 indicating that exhaust air from the second space 22 is ON.

[0090] Figure 13 is an operation diagram of the air conditioning system 1 shown in Embodiment 3. Here, we will explain the differences between Figure 13 and Figure 8.

[0091] In Figure 13, steps C2, C3, C4, C5, and C9 in Figure 3 correspond to C12, C13, C14, C15, and C19, respectively. Also, steps C6a, C7a, and C10a in Figure 8 correspond to C16, C17, and C20, respectively. Steps other than C12, C13, C14, C15, C16, C17, C19, and C20 are the same as in Figure 3.

[0092] In step C12, the communication unit 62 sends a request to read the humidity control status of the air conditioner 11 and receives a response regarding the humidity control status of the air conditioner 11. The control unit 63 determines whether the humidity control status is ON. Note that the humidity control status refers to the state in which humidity control is ON or OFF. When the humidity control status is not ON, the control unit 63 performs the following operation (step C17). When the humidity control status is ON, the control unit 63 performs the following operation (step C13).

[0093] In step C13, the humidity set in the air conditioner 11 is called the set humidity. The communication unit 62 sends a request for this set humidity to the air conditioner 11. When the air conditioner 11 receives the request for the set humidity, it reads the set humidity. The air conditioner 11 sends a response of the read set humidity to the communication unit 62. The communication unit 62 receives the response of the set humidity sent from the air conditioner 11. Similarly, the humidity measured by the first humidity sensor 33 is called the first measured humidity. The communication unit 62 sends a request for this first measured humidity to the first humidity sensor 33. When the first humidity sensor 33 receives the request for the first measured humidity, the first humidity sensor 33 measures the humidity. When the first humidity sensor 33 has finished measuring the humidity, the first humidity sensor 33 sends a response of the measured first measured humidity to the communication unit 62. The communication unit 62 receives the response of the first measured humidity sent from the first humidity sensor 33. Similarly, the humidity measured by the second humidity sensor 34 is called the second measured humidity. The communication unit 62 sends a request for this second measured humidity to the second humidity sensor 34. When the second humidity sensor 34 receives the request for the second measured humidity, it measures the humidity. Once the second humidity sensor 34 has finished measuring the humidity, it sends a response of the measured second measured humidity to the communication unit 62. The communication unit 62 receives the response of the second measured humidity sent from the second humidity sensor 34. In this way, the control unit 63 acquires the set humidity of the air conditioner 11, the first measured humidity of the first humidity sensor 33, and the second measured humidity of the second humidity sensor 34. Hereafter, an example of humidity control in Embodiment 3 will be shown step by step.

[0094] As a prerequisite for controlling step C13, the memory 100b of the control unit 63 has pre-stored the third threshold and the fourth threshold. The third threshold is the value at which it is determined that the first measured humidity is approaching the set humidity. The fourth threshold is the value at which it is determined that the first measured humidity and the second measured humidity are far apart.

[0095] In the humidity control example in step C13, the humidity set by the user for air conditioning is 60%, the humidity measured by the first humidity sensor 33 is 90%, the humidity measured by the second humidity sensor 34 is 95%, the predetermined third threshold is 5%, and the predetermined fourth threshold is 5%.

[0096] In step C14, the difference between the set humidity and the first measured humidity is called the set humidity difference. The control unit 63 calculates the absolute value of the set humidity difference. It then determines whether the calculated absolute value of the set humidity difference is less than or equal to the third threshold. If the value is not below the third threshold, the control unit 63 performs the following operation (step C17). When the value is below the third threshold, the control unit 63 proceeds to the next determination (step C15).

[0097] In the humidity control example in step C14, when the set humidity is 60% and the first measured humidity is 85%, step C17 is executed. On the other hand, when the set humidity is 60% and the first measured humidity is 65%, the absolute value of the difference in set humidity is 5%, which satisfies the third threshold of 5% or less, so the process proceeds to step C15.

[0098] In step C15, the difference between the first measured humidity and the second measured humidity is called the ambient humidity difference. The control unit 63 calculates the absolute value of the ambient humidity difference. It then determines whether the calculated absolute value of the ambient humidity difference exceeds the fourth threshold. If the fourth threshold is not exceeded, the control unit 63 performs the following operation (step C17). When the fourth threshold is exceeded, the control unit 63 performs the following operation (step C16).

[0099] In the humidity control example in step C15, when the first measured humidity is 60% and the second measured humidity is 60%, the absolute value of the spatial humidity difference is 0%, which does not exceed the fourth threshold of 5%, so step C17 is executed. On the other hand, when the first measured humidity is 60% and the second measured humidity is 95%, the absolute value of the difference is 35%, which exceeds the fourth threshold of 5%, so step C16 is executed.

[0100] In step C16, the operation of the switchgear 51, the second switchgear 52, and the first fan 53 is the same as in step C6a. The operation of the second fan 55 will be described below. The communication unit 62 sends a request to the second fan 55 to exhaust air from the second space 22, and the second fan 55 receives the request to exhaust air from the second space 22. If the second fan 55 is already exhausting air from the second space 22, it maintains that state and completes the process. If the second fan 55 is not exhausting air from the second space 22, it starts exhausting air and completes the process by turning on the exhaust from the second space 22. After that, the second fan 55 sends a response to the communication unit 62 indicating that it is exhausting air from the second space 22, and the communication unit 62 receives the response from the second fan 55 indicating that it is exhausting air from the second space 22. A first fan 53 blows air from the bottom of the partition 12, sending the humidity-controlled air from the first space 21 to the bottom of the second space 22. At the same time, a second fan 55 exhausts the unhumidified air from the second space 22 from the top of the partition 12. In this way, the humidity of the second space 22 is controlled. After performing step C16, the control unit 63 performs the next operation (step C8).

[0101] In step C17, the operation of the switchgear 51, the second switchgear 52, and the first fan 53 is the same as in step C7a. The operation of the second fan 55 will be described below. The communication unit 62 sends a stop request to the second fan 55, and the second fan 55 receives the stop request. If the second fan 55 has not stopped exhausting, it stops exhausting and completes the process by setting the exhaust to OFF state. After that, the second fan 55 sends an exhaust OFF response to the communication unit 62, and the communication unit 62 receives the exhaust OFF response from the second fan 55. After performing step C17, the control unit 63 performs the next operation (step C8).

[0102] In step C19, the state in which the user has turned OFF the humidity control for the second space 22 is referred to as the second space air conditioning OFF state. The communication unit 62 sends a request for the second space air conditioning OFF state to the control panel 71, and the control panel 71 receives the request for the second space air conditioning OFF state. The control panel 71 reads the second space air conditioning OFF state and sends a response of the second space air conditioning OFF state to the communication unit 62. The same procedure is followed between the communication unit 62 and the second control panel 72. The control unit 63 determines whether the second space air conditioning is in the OFF state. If the second space air conditioning is not in the OFF state, the control unit 63 proceeds to the next determination (step C1). When the second space air conditioning is OFF, the control unit 63 performs the following operation (step C20).

[0103] In step C20, the operation of the switchgear 51, the second switchgear 52, and the first fan 53 is the same as in step C10a. The operation of the second fan 55 will be described below. The communication unit 62 sends a stop request to the second fan 55, and the second fan 55 receives the stop request. If the second fan 55 has not stopped exhausting, it stops exhausting and completes the process by setting the exhaust to OFF state. After that, the second fan 55 sends an exhaust OFF response to the communication unit 62, and the communication unit 62 receives the exhaust OFF response from the second fan 55. The user has turned OFF the humidity control for the second space 22, so the operation is complete.

[0104] Thus, in addition to the second embodiment, a first humidity sensor 33 is installed in the first space 21, and a second humidity sensor 34 is installed in the second space 22. Furthermore, a switch 51 and a first fan 53 are installed in a connecting section 41 that connects the lower part of the first space 21 and the lower part of the second space 22. A second switch 52 and a second fan 55 are installed in a second connecting section 42 that connects the upper part of the first space 21 and the upper part of the second space 22. The communication unit 62 acquires the set humidity of the air conditioner 11, the first measured humidity of the first humidity sensor 33, and the second measured humidity of the second humidity sensor 34. When the control unit 63 calculates the absolute value of the difference between the set humidity and the first measured humidity and determines that it is within the range of the third threshold, and when the control unit 63 calculates the absolute value of the difference between the first measured humidity and the second measured humidity and determines that it exceeds the fourth threshold, the switchgear 51 and the second switchgear 52 are opened, the first fan 53 blows air, and the second fan 55 exhausts air, thereby sending the humidity-controlled air from the first space 21 to the second space 22, and improving the comfort of users in the second space 22.

[0105] Figure 14 is an operation diagram of the air conditioning system 1 showing a modified example of Embodiment 3.

[0106] The configuration in Figure 12 remains unchanged, but the forced timer operation, specifically the timer time display 85 (for example, 60 minutes) using the "Timer" button 82, and the air conditioning OFF for the second space 22 using the "Off" button 81, are both pressed and held simultaneously for a certain period of time, for example, 5 seconds. In this way, unlike the waiting time T in step C8, even if humidity control is not complete, the humidity control for the second space 22 is forcibly turned OFF by the 60-minute timer. Note that in the modified example of this embodiment 3, the forced timer is shown as 60 minutes remaining in the display in Figure 15, but the forced timer could be, for example, from D1 day H1 hour M1 minute to D2 day H2 hour M2 minute, as long as a period of time is defined.

[0107] Let's explain the specific differences in steps between Figure 14 and Figure 8.

[0108] Steps C51, C52, and C53 are added. These are steps controlled by the forced timer Ta.

[0109] In step C51, for example, the user operates the forced timer Ta on the second control panel 72. Upon receiving the operation, the second control panel 72 stores that the forced timer Ta is ON and the value of the forced timer Ta. The communication unit 62 sends a request to the second control panel 72 that the forced timer Ta is ON, and the second control panel 72 receives the request that the forced timer Ta is ON. Upon receiving the request, the second control panel 72 reads that the forced timer Ta is ON and sends a response to the communication unit 62 that the forced timer Ta is ON. The control unit 63 determines whether the state of the forced timer Ta is ON.

[0110] Figure 15 shows an example of humidity control of control panel 71 and second control panel 72 during step C51. Switching devices 51 and 2nd switching device 52 are in the open state, and the background color indicating switching devices 51 and 2nd switching device 52 is shown as white. The first fan 53 blows the humidity-controlled air from the first space 21 to the second space 22. The second fan 55 exhausts unhumidified air from the second space 22 to the first space 21. The arrow 92 illustrates how humidity-controlled air in the first space 21 is sent to the second space 22 from the bottom of the partition 12 by the first fan 53, and how unhumidified air from the second space 22 is exhausted from the top of the partition 12 by the second fan 55. The forced timer display 85 is 60 minutes.

[0111] In step C52, the communication unit 62 sends a request for the value of the forced timer Ta to the second control panel 72, and the second control panel 72 receives the request for the value of the forced timer Ta. Upon receiving the request, the second control panel 72 reads the value of the forced timer Ta and sends a response to the communication unit 62 stating that the value of the forced timer Ta is, for example, 60 minutes. The communication unit 62 receives the response stating that the value of the forced timer Ta is, for example, 60 minutes. The control unit 63 counts down the value of the forced timer Ta. For example, if the value of the forced timer Ta is 60 minutes, it counts down 1 second at a time from 60 minutes until it reaches 0 seconds. When the countdown of the forced timer Ta reaches 0 seconds, the control unit 63 performs the following operation (step C53).

[0112] When the control unit 63 is operating at least one of cooling, heating, and humidity control, the air conditioning in the second space 22 is set to ON. When the control unit 63 stops cooling, heating, and humidity control, the air conditioning in the second space is set to OFF.

[0113] In step C53, the control unit 63 forcibly switches the second space air conditioning to the OFF state. The control unit 63 performs the following operation (step C20).

[0114] Figure 16 shows an example of humidity control on the control panel 71 and the second control panel 72 during step C53, which illustrates a modified version of Embodiment 5. The switchgear 51 and the second switchgear 52 are in the closed state, and the background color indicating the switchgear 51 and the second switchgear 52, as well as the second space "Off" button 81, are displayed in black. The arrow in the second space 22 of Figure 15 is not displayed. Also, the timer time display 85, which indicates a forced termination, is displayed as 0 seconds.

[0115] In this way, when users plan how long they will stay in the second space 22, they can operate the second control panel 72 to set the time by first operating the forced timer Ta, which causes the control unit 63 to count down and turn off the air conditioning in the second space 22, thereby further improving convenience.

[0116] Embodiment 4. Figure 17 is a diagram showing the configuration of the air conditioning system 1, including the exterior of the building, as in Embodiment 4.

[0117] Embodiment 4 omits details similar to those in Embodiment 3 and describes a different configuration. Instead of the control device 61, it is connected to a cloud 64 via the internet. The cloud 64 may be a server or the like. Inside the cloud 64 are a communication unit 62a, which has the same functions as the communication unit 62, and a control unit 63a, which has the same functions as the control unit 63. Similar to the control device 61, the communication unit 62a and the control unit 63a in the cloud 64 are connected in a way that allows them to communicate with each other. Router 65 is connected to communication unit 62a via the internet. Router 65 is also connected to the building's air conditioner 11a, motion sensor 35, switchgear 51, second switchgear 52, first fan 53, second fan 55, control panel 71, and second control panel 72 in a communicative manner.

[0118] The air conditioner 11a is installed in the first space 21. The first temperature sensor 31 and the first humidity sensor 33 are built into the air conditioner 11a. The function of the first temperature sensor 31 is the same as in Embodiment 1, and the function of the first humidity sensor 33 is the same as in Embodiment 3.

[0119] The motion sensor 35 is installed in the second space 22. The motion sensor 35 is a sensor that detects people. Examples of people-detecting sensors include, but are not limited to, infrared sensors, ultrasonic sensors, microwave sensors, and photoelectric sensors. When the motion sensor 35 is installed, it is in a state where it does not detect people (OFF). When the motion sensor 35 detects a person, it switches to a state where a person has been detected (ON). The motion sensor 35 incorporates a second temperature sensor 32 and a second humidity sensor 34. The function of the second temperature sensor 32 is the same as in Embodiment 1, and the function of the second humidity sensor 34 is the same as in Embodiment 3.

[0120] Figure 18 is an operational diagram of the air conditioning system 1, including the exterior of the building, showing Embodiment 4. Here, we will explain the differences between Figure 18 and Figure 13, and the operation in which part of Figure 10 is included in Figure 18.

[0121] Figure 18 shows that steps C12, C13, and C19 in Figure 13 are replaced with C12a, C13a, and C19a, respectively. Furthermore, Figure 18 uses the conditions for steps C4 and C5 in Figure 10 and the conditions for steps C14 and C15 in Figure 13.

[0122] In step C12a, the communication unit 62a sends a request to the control panel 71 to read the humidity control and cooling status or humidity control and heating status of the air conditioner 11a, and receives a response from the control panel 71 regarding the humidity control and cooling status or humidity control and heating status of the air conditioner 11a. Communication between the communication unit 62a and the second control panel 72 is similar. The control unit 63a determines whether the humidity control and cooling or humidity control and heating status is ON. The state of humidity control and cooling refers to the state where cooling is ON and humidity control is ON, or cooling is OFF and humidity control is OFF. The state of humidity control and heating refers to the state where heating is ON and humidity control is ON, or heating is OFF and humidity control is OFF. Furthermore, air conditioning and heating are controlled mutually. When the humidity control and cooling, or humidity control and heating, is not ON, the control unit 63a performs the following operation (step C17). When the humidity control and cooling or humidity control and heating state is ON, the control unit 63a performs the following operation (step C13a).

[0123] In step C13a, the temperature and humidity set in the air conditioner 11a are referred to as the set temperature and set humidity, respectively. The communication unit 62a sends a request for this set temperature and set humidity to the air conditioner 11a. When the air conditioner 11a receives the request for the set temperature and set humidity, the air conditioner 11a reads the set temperature and set humidity. The air conditioner 11a sends a response to the communication unit 62a with the read set temperature and set humidity. The communication unit 62a receives the response with the set temperature and set humidity sent from the air conditioner 11a. The humidity measured by the first temperature sensor 31 and the first humidity sensor 33 built into the air conditioner 11a is called the first measured temperature and the first measured humidity. The communication unit 62a transmits a request for these first measured temperature and first measured humidity to the air conditioner 11a. When the air conditioner 11a receives the request for the first measured temperature and first measured humidity, the air conditioner 11a measures the temperature and humidity of the first space 21. When the air conditioner 11a has finished measuring the temperature and humidity of the first space 21, the air conditioner 11a transmits a response of the measured first measured temperature and first measured humidity to the communication unit 62a. The communication unit 62a receives the response of the first measured temperature and first measured humidity transmitted from the air conditioner 11a. The humidity measured by the second temperature sensor 32 and the second humidity sensor 34, which are built into the human presence sensor 35, are called the second measured temperature and the second measured humidity. The communication unit 62a transmits a request for these second measured temperature and second measured humidity to the human presence sensor 35. When the human presence sensor 35 receives the request for the second measured temperature and second measured humidity, the human presence sensor 35 measures the second measured temperature and second measured humidity. When the human presence sensor 35 has finished measuring the second measured temperature and second measured humidity, the human presence sensor 35 transmits a response of the measured second measured temperature and second measured humidity to the communication unit 62a. The communication unit 62a receives the response of the second measured temperature and second measured humidity transmitted from the human presence sensor 35. In this way, the control unit 63a acquires the set temperature, set humidity, first measured temperature and first measured humidity of the air conditioner 11a, as well as the second measured temperature and second measured humidity of the human presence sensor 35.

[0124] In step C61, when the motion sensor 35 detects a person in the second space 22, the motion sensor 35 transmits a message to the communication unit 62a via the router 65 indicating that a person has been detected in the second space 22 (ON). The communication unit 62a receives the message from the motion sensor 35 indicating that a person has been detected in the second space 22 (ON). The control unit 63a stores the message indicating that a person has been detected in the second space 22 (ON). When the human detection state is not ON, the control unit 63a performs the following operation (step C17). When the human detection state is ON, the control unit 63a performs the following operation (step C16).

[0125] Figure 19 shows an example of the control panel 71 and the second control panel 72 in a state where the motion sensor 35 did not detect a person in step C61 and the process proceeded to step C17. The user has previously operated the "motion sensor" button 84, and the background color of the "motion sensor" button 84 is displayed as white. The graphic representing the radio waves in the second space 22 indicates that the system is in the process of detecting a person. Since no person has been detected, the shape of a person is not displayed.

[0126] Figure 20 shows an example of the control panel 71 and the second control panel 72 in the state where the motion sensor 35 has detected a person in step C61 and the system has proceeded to step C16. The user has previously operated the "motion sensor" button 84, and the background color of the "motion sensor" button 84 is displayed as white. The graphic representing the radio waves in the second space 22 indicates that the system is performing the action of detecting a person. Because a person has been detected, a human shape display 94 is shown. The human shape display 94 can be any shape as long as it clearly indicates that a person is in the second space 22. Furthermore, the background color of the opening / closing device 51 and the second opening / closing device 52 is displayed as white to indicate that the opening / closing device 51 and the second opening / closing device 52 are open. Also, the arrow 92 shows that the first fan 53 is blowing humidity-controlled cool air from the first space 21 to the second space 22, and the air in the second space 22 is being exhausted to the first space 21 from the top of the partition 12 by the second fan 55.

[0127] In step C19a, the state in which the user has turned OFF the humidity control and cooling, or humidity control and heating, of the second space 22 is referred to as the second space air conditioning OFF state. The communication unit 62a sends a request for the second space air conditioning OFF state to the control panel 71, and the control panel 71 receives the request for the second space air conditioning OFF state. The control panel 71 reads the second space air conditioning OFF state and sends a response of the second space air conditioning OFF state to the communication unit 62a. The same procedure is followed between the communication unit 62a and the second control panel 72. The control unit 63a determines whether the second space air conditioning is in the OFF state. When the second space 22 is in the second space air conditioning OFF state, the control unit 63a performs the following operation (step C20). If the second space 22 is not in the second space air conditioning OFF state, the control unit 63a proceeds to the next determination (step C1).

[0128] In this way, by detecting people using the motion sensor 35, the air conditioning in the second space 22 can be controlled without user intervention only when a user is present in the second space 22, thus improving convenience.
