Patent document 1: japanese laid-open patent publication No. 2009-299933

However, the air conditioning control device disclosed in patent document 1 determines the number of users present in each area based on the difference between the area image when the user is not present and the current area image. Therefore, it is unclear whether or not the person in the area needs air conditioning. Therefore, in the air conditioning system to which the air conditioning control device disclosed in patent document 1 is applied, the air conditioner is operated even if the person in the area does not need air conditioning. Therefore, patent document 1 may consume electric power in vain.

According to the present invention, the control unit controls the plurality of air conditioners that perform air conditioning corresponding to each of the plurality of zones, based on the setting information communicated via the wireless communication module. Therefore, each air conditioner operates according to setting information arbitrarily input to the information communication terminal by a user or the like, for example. Therefore, the air conditioning system performs only a necessary amount of air conditioning, and is therefore advantageous for energy saving.

Embodiment mode 1

The air conditioning system 1 according to embodiment 1 will be described below with reference to the drawings. Fig. 1 is a schematic diagram showing an air conditioning system 1 according to embodiment 1. Fig. 2 is a schematic diagram showing the room to be air-conditioned 11 according to embodiment 1. As shown in fig. 1, the air conditioning system 1 is installed in an air conditioning target room 11, and includes: a plurality of air conditioners 41, an information communication terminal 42, a wireless communication module 43, an infrared sensor module 44, a control unit 45, and a storage unit 46.

(air Conditioning object Chamber 11)

The air-conditioning target room 11 is a room formed by a floor 21, wall surfaces 22, and a ceiling 23. An internal space of the air-conditioning target room 11 enclosed by the floor 21, the wall 22, and the ceiling 23 is referred to as an indoor space 30. As shown in fig. 2, for example, a table 24, a chair 25, and a shelf 26 are disposed above the floor 21 of the air-conditioning object room 11.

(air conditioner 41)

Fig. 3 is a plan view showing the room to be air-conditioned 11 according to embodiment 1. The air conditioner 41 includes an outdoor unit 51 and an indoor unit 52. The outdoor unit 51 circulates the refrigerant, which has exchanged heat with outdoor air, to the indoor units 52. As shown in fig. 3, a plurality of indoor units 52 are disposed on the ceiling 23, the wall surface 22, or the like of the air-conditioning target room 11, and air-conditioning is performed in the indoor space 30. With the arrangement of the plurality of indoor units 52 in the air-conditioning target room 11, the indoor space 30 is partitioned into a plurality of air-conditioning areas 31 in which the respective air conditioners 41 perform air-conditioning. That is, each air conditioner 41 performs air conditioning in the indoor space 30 partitioned into the plurality of air-conditioning areas 31, in correspondence with each of the plurality of air-conditioning areas 31. Each air conditioner 41 has a remote controller 29. The remote controller 29 receives an operation mode of the air conditioner 41, a set temperature, and the like. In fig. 3, 4 indoor units 52 are shown, but 2, 3, or 5 or more indoor units may be used. In addition, one indoor unit 52 may not be connected to one outdoor unit 51, and for example, a plurality of indoor units 52 may be connected to one outdoor unit 51. The air conditioner 41 may be a cooling fan, a heater, or the like.

(information communication terminal 42)

The information communication terminal 42 is, for example, a smartphone or a tablet terminal held by a user of the air-conditioned room 11. The information communication terminal 42 communicates with the wireless communication module 43 using a wireless communication function, and instructs the air conditioner 41 of the operation contents. The wireless communication function is, for example, a wireless LAN such as Bluetooth (registered trademark, the same hereinafter), WiFi (registered trademark, the same hereinafter), ZigBee (registered trademark, the same hereinafter), or the like. Furthermore, Bluetooth includes BLE (Bluetooth Low Energy).

Setting information that is set for each air conditioner 41 and indicates the operation content of each air conditioner 41 is input to the information communication terminal 42. Here, the setting information includes automatic operation start condition information, automatic operation start setting information, manual operation setting information, and the like. The automatic operation start condition information is a condition for determining whether or not to start the operation of the air conditioner 41 when the air conditioner 41 is stopped. The automatic operation start condition information is, for example, an air temperature, a period, a time zone, or the like. The automatic operation start setting information is a setting of an operation method of the air conditioner 41 when the automatic operation start condition information is satisfied and the air conditioner 41 starts to operate. The automatic operation start setting information is, for example, an operation mode, a set temperature, a wind direction, or the like of the indoor unit 52. The manual operation setting information indicates an operation method for operating the air conditioner 41 when an input is made by the information communication terminal 42. The manual operation setting information is, for example, the operation mode, the set temperature, the wind direction, or the like of the indoor unit 52, similar to the automatic operation start setting information. The information communication terminal 42 includes an operation unit 61 and a display 62.

(operation section 61)

Fig. 4 is a functional block diagram showing the operation unit 61 according to embodiment 1. The operation unit 61 is, for example, an application installed in the information communication terminal 42. The operation unit 61 includes a region setting means 63, an automatic operation setting means 64, an automatic operation start means 65, and a manual operation instruction means 66. The region setting means 63, the automatic operation setting means 64, the automatic operation starting means 65, and the manual operation instructing means 66 are constituted by algorithms. The area setting means 63, the automatic operation setting means 64, the automatic operation starting means 65, and the manual operation instructing means 66 are executed independently in each information communication terminal 42 owned by the user.

(area setting unit 63)

Fig. 5 is a plan view showing the control area 32 according to embodiment 1. Fig. 6 is a schematic diagram showing the information communication terminal 42 according to embodiment 1. Fig. 7 is a plan view showing the detection region 33 according to embodiment 1. Fig. 8 is a plan view showing the detection region 33 according to embodiment 1. The area setting unit 63 sets the detection area 33 for each air conditioner 41. The detection area 33 is an area to be detected by room temperature, human body, and the like used for controlling each air conditioner 41. Here, the operation of the area setting section 63 will be described with reference to fig. 5 to 8.

First, the control area 32 is allocated to each air conditioner 41. The control area 32 is an area automatically set based on the arrangement position of the indoor units 52 of each air conditioner 41. As shown in fig. 5, when 4 indoor units 52 are set at substantially equal intervals on four sides of the indoor space 30, each control area 32 is an area obtained by equally dividing the indoor space 30 into four. Next, the detection area 33 is obtained by selecting an arbitrary area from a screen of an application program that displays the indoor space 30 in a simulated manner as shown in fig. 6. The detection area 33 may be set by detecting, by the infrared sensor module 44, an area surrounded by a plurality of beacons (not shown) that irradiate infrared rays, such as the floor 21 disposed in the air-conditioned room 11. Thus, as shown in fig. 7, the detection area 33 is set to an area obtained by removing an area such as the rack 26, which a person cannot enter, from the control area 32.

The detection area 33 may be set to be wider than the air-conditioning area 31. The detection regions 33 may be overlapped regions or may not be in contact with each other. As shown in fig. 8, the control area 32 may be used as it is in the detection area 33.

(automatic operation setting unit 64)

The automatic operation setting means 64 stores the automatic operation start condition information and the automatic operation start setting information input in correspondence with the respective air conditioners 41 in a storage unit (not shown) of the information communication terminal 42. The number of the automatic operation start condition information may be 1 or more. In addition, the automatic operation start setting information may not be input.

(automatic operation start unit 65)

The automatic operation start unit 65 transmits an operation start instruction to the air conditioner 41 via the wireless communication module 43 when the information acquired from the wireless communication module 43 satisfies the automatic operation start condition information set by the automatic operation setting unit 64.

(Manual operation instruction unit 66)

The manual operation instructing unit 66 instructs the control unit 45 via the wireless communication module 43 to operate any air conditioner 41 based on the manual operation setting information. That is, the manual operation instruction unit 66 performs the same operation as the remote controller 29 of the air conditioner 41.

(display 62)

The display 62 is a display device that displays a screen or the like for operating an application of the information communication terminal 42, as shown in fig. 6. The display 62 may display, for example, automatic operation start condition information and automatic operation start setting information, and information such as the temperature and the wind direction acquired from the wireless communication module 43.

(Wireless communication module 43)

Fig. 9 is a plan view showing the detection area 33 and the communication-capable area 34 according to embodiment 1. The wireless communication module 43 communicates with the information communication terminal 42. As shown in fig. 1, the wireless communication module 43 is provided integrally with the control section 45. The wireless communication module 43 may be separate from the controller 45, connected to the controller 45 through the communication line 27, and communicate with the controller 45. The wireless communication module 43 is connected to each air conditioner 41 via the communication line 27.

The wireless communication module 43 is provided with a communicable area 34. The communication-capable area 34 is an area to which radio waves of an intensity that can be received by the information communication terminal 42 reach. For example, as shown in fig. 9, the communicable area 34 is set to be wider than each detection area 33. Thereby, the wireless communication module 43 performs wireless communication with the information communication terminal 42 existing inside the detection area 33, the information communication terminal 42 in proximity to the detection area 33, or the like.

(Infrared sensor module 44)

Fig. 10 is a schematic diagram showing the control unit 45 and the infrared sensor module 44 according to embodiment 1. For example, as shown in fig. 5, the infrared sensor module 44 is provided with 1 in the center of the ceiling 23 of the air-conditioning target room 11, measures the temperature of all the detection areas 33, and includes a sensor unit 71 (see fig. 11), a motor 73, and an infrared sensor 72. As shown in fig. 10, the infrared sensor module 44 and the control unit 45 are separate bodies and are connected by a communication line 27. The infrared sensor module 44 may be provided integrally with the control unit 45. The infrared sensor module 44 is attached to the ceiling 23 via the leaf spring 28.

The sensor unit 71 controls the operation of the motor 73. The infrared sensor 72 detects the temperature of the floor 21 of the detection area 33, the surface temperature of the human body existing in the detection area 33, the number of persons existing, and the position of the human body by the reaction of internal elements (not shown) to infrared rays. The element used in the infrared sensor 72 is constituted by a single element. Infrared sensor 72 is attached to motor 73 in a state of being inclined with respect to a direction perpendicular to ceiling 23. The motor 73 rotates the infrared sensor 72 by 360 ° using a line perpendicular to the ceiling 23 passing through a base (not shown) to which the infrared sensor 72 is attached as a rotation axis, and detects the temperature of all the detection regions 33. In addition, each time the motor 73 rotates the infrared sensor 72 by several degrees, the infrared sensor 72 detects infrared rays. The range in which the infrared sensor 72 detects infrared rays at a time is narrower than the size of a human body, for example.

In this way, since the infrared sensor module 44 rotates the infrared sensor 72 by the motor 73, it is possible to detect all the detection regions 33 and improve the resolution. Since the infrared sensor 72 is formed of a single element, temperature correction between a plurality of elements is not necessary. The infrared sensor 72 may not be constituted by a single element. Even in this case, since 1 infrared sensor module 44 is provided in the central portion of the ceiling 23 of the air-conditioning target room 11, temperature correction is easier than in the case where a plurality of infrared sensor modules 44 are provided.

The controller 45 controls the operation of each air conditioner 41. The control Unit 45 is configured by dedicated hardware or a CPU (also referred to as a Central Processing Unit, a Processing Unit, an arithmetic Unit, a microprocessor, a microcomputer, or a processor) that executes a program stored in the storage Unit 46 (see fig. 11). When the control unit 45 is dedicated hardware, the control unit 45 corresponds to, for example, a single circuit, a composite circuit, an asic (application Specific Integrated circuit), an FPGA (Field-Programmable Gate Array), or a combination thereof. Each of the functional units realized by the control unit 45 may be realized by separate hardware, or each of the functional units may be realized by 1 piece of hardware.

When the control unit 45 is a CPU, each function executed by the control unit 45 is realized by software, firmware, or a combination of software and firmware. The software and firmware are described as programs and are stored in the storage unit 46 (not shown). The CPU reads and executes the program stored in the storage unit 46 to realize each function. Here, the storage unit 46 is a nonvolatile or volatile semiconductor memory such as a RAM, a ROM, a flash memory, an EPROM, and an EEPROM. Further, a part of the function of the control unit 45 may be realized by dedicated hardware, and a part may be realized by software or firmware.

Fig. 11 is a functional block diagram showing the control unit 45 according to embodiment 1. As shown in fig. 11, the control unit 45 includes an environment recognition unit 81, a wireless communication unit 82, a control information calculation unit 83, and an output unit 84. The environment recognition unit 81, the wireless communication unit 82, the control information calculation unit 83, and the output unit 84 are configured by an algorithm.

(Environment recognizing unit 81)

The environment recognition unit 81 is for recognizing environment information, and is configured by an environment information acquisition unit 91 and an environment information storage unit 92. The environmental information is, for example, the room temperature or the human body position of the detection area 33 and the operating state of the air conditioner 41. The environmental information acquisition unit 91 acquires environmental information such as the room temperature or the position of the human body in the detection area 33 detected by the infrared sensor 72 from the sensor unit 71. The environmental information acquisition unit 91 may acquire environmental information such as the room temperature of the room 11 to be air-conditioned, using a temperature sensor (not shown) provided in the air conditioner 41 or a temperature sensor (not shown) provided in the remote controller 29. The environmental information acquisition unit 91 may obtain an average value from the plurality of room temperatures. The environmental information acquisition unit 91 acquires environmental information such as an operation mode, a set temperature, and an air volume of each air conditioner 41 from each air conditioner 41. The environment information storage unit 92 stores the environment information acquired by the environment information acquisition unit 91 in the storage unit 46.

(Wireless communication unit 82)

The wireless communication unit 82 is used for receiving the setting information from the wireless communication module 43, and includes a setting information acquisition unit 93 and a setting information storage unit 94. The setting information acquisition unit 93 acquires the automatic operation start setting information and the manual operation setting information set in the information communication terminal 42 via the wireless communication module 43. The setting information storage unit 94 stores the automatic operation start setting information and the manual operation setting information acquired by the setting information acquisition unit 93 in the storage portion 46.

(control information arithmetic unit 83)

The control information arithmetic unit 83 is for performing arithmetic operation on the control information outputted by the output unit 84, and is composed of an arithmetic unit 95 and a result storage unit 96. The control information is, for example, air conditioning control information indicating the operation amount of each device of the air conditioner 41 when adjusting the operation mode, the set temperature, the air volume, or the like of the air conditioner 41. The control information is, for example, sensor control information indicating an operation amount of the motor 73 to drive the infrared sensor 72 toward the specific detection region 33. The arithmetic unit 95 calculates the control information using the environment information and the setting information stored in the storage unit 46. The calculation unit 95 calculates the air conditioning control information so that the sensible temperature obtained by correcting the suction temperature of the air conditioner 41 based on the temperature of the floor 21 and the setting information of the room temperature become equal to each other, for example. The calculation unit 95 may calculate the air conditioning control information so that the wind direction and the air volume are adjusted according to the position of the human body. The result storage unit 96 stores the control information calculated by the calculation unit 95 in the storage unit 46.

(output unit 84)

The output unit 84 is used for outputting environment information, setting information, and control information to each device included in the air conditioning system 1, and is configured by a display unit 97, a sensor control unit 98, and an air conditioning control unit 99. The display unit 97 displays the environment information and the setting information stored in the storage unit 46 on the display 62 of the information communication terminal 42 via the wireless communication module 43. The sensor control unit 98 communicates the sensor control information stored in the storage unit 46 to the sensor unit 71 of the infrared sensor module 44. The air-conditioning control unit 99 transmits the air-conditioning control information stored in the storage unit 46 to each air conditioner 41. The air conditioning control unit 99 may cause the air conditioner 41 to perform an air blowing operation before the infrared sensor 72 or a temperature sensor provided in the air conditioner 41 or the remote controller 29 detects the temperature.

The control unit 45 may communicate with an external server provided outside the air conditioning system 1 to transfer information stored in the storage unit 46.

(storage section 46)

The storage unit 46 stores environment information recognized by the environment recognition unit 81, setting information received from the wireless communication module 43, control information calculated by the control information calculation unit 83, and the like.

(automatic operation instruction by information communication terminal 42)

Fig. 12 is a flowchart showing the operation of the information communication terminal 42 according to embodiment 1. Here, a description will be given of a procedure in which the information communication terminal 42 transmits an operation instruction to the air conditioner 41. As shown in fig. 12, as a premise, the information communication terminal 42 enables wireless communication with the wireless communication module 43. Here, the state in which the wireless communication with the wireless communication module 43 is enabled in the information communication terminal 42 is, for example: the application started in the background is in a standby state in which the setting for automatically operating the air conditioner 41 is effective.

At this time, first, the automatic operation start means 65 determines whether or not a predetermined time of 30 minutes has elapsed from the time of the previous attempt to connect to the wireless communication module 43 (step S1). The predetermined time may be less than 30 minutes or more than 30 minutes. Next, when the predetermined time has elapsed (yes at step S1), the automatic operation start unit 65 determines whether or not the time during which the information communication terminal 42 receives the radio wave transmitted from the wireless communication module 43 at the intensity of the threshold value of-70 dBm or more has continued for the threshold time of 2 seconds (step S2). That is, automatic operation starting section 65 determines whether or not information communication terminal 42 is present in communication-capable area 34. The threshold value of the radio wave intensity may be set to less than-70 dBm or more than-70 dBm. The threshold time may be set to less than 2 seconds or more than 2 seconds.

When the time during which the information communication terminal 42 receives the radio wave transmitted from the wireless communication module 43 with the intensity equal to or higher than the threshold continues for the threshold time (yes at step S2), the automatic operation start means 65 displays the application program of the information communication terminal 42 on the display 62. The automatic operation start means 65 connects the information communication terminal 42 to the wireless communication module 43 (step S3). Finally, when the automatic operation start condition information set in the automatic operation setting unit 64 is satisfied (yes in step S4), the automatic operation start unit 65 transmits an operation instruction to the air conditioner 41 set in the automatic operation start setting information via the wireless communication module 43 (step S5). In addition, as described above, when a plurality of pieces of automatic operation start condition information are set, any one of the pieces of automatic operation start condition information may be satisfied.

When the predetermined time has not elapsed since the time of the previous attempt to connect to the wireless communication module 43 (no at step S1), the automatic operation start unit 65 repeatedly determines whether or not the predetermined time has elapsed (step S1). That is, the information communication terminal 42 cannot transmit the operation instruction to the air conditioner 41 for a predetermined time. When the time during which the information communication terminal 42 receives the radio wave transmitted from the wireless communication module 43 at the intensity equal to or higher than the threshold does not continue for the threshold time (no at step S2), the automatic operation start unit 65 determines again whether or not the predetermined time has elapsed (step S1). When the automatic operation start condition information set in the automatic operation setting means 64 is not satisfied (no in step S4), the automatic operation start means 65 determines again whether or not the predetermined time has elapsed (step S1).

(operation of the control section 45)

Fig. 13 is a flowchart showing the operation of the control unit 45 according to embodiment 1. The operation of the control unit 45 that receives the operation instruction from the information communication terminal 42 will be described in detail with reference to fig. 13. First, when the setting information acquisition unit 93 acquires the setting information (step S11), the arithmetic unit 95 calculates the air conditioning control information (step S12). Next, the air conditioning control unit 99 transmits air conditioning control information to the air conditioner 41 (step S13). Thereby, the air conditioner 41 starts operation based on the air conditioning control information received from the air conditioning control unit 99. At this time, if the automatic operation start setting information is not set, the air conditioner 41 starts operation according to the operation contents in the previous operation. In this way, the information communication terminal 42 that is enabled by wireless communication exists in the communication-capable area 34, and the air conditioner 41 automatically starts operating.

The air conditioner 41 that has started operation does not receive execution of the automatic operation starting means 65 by the information communication terminal 42. Therefore, the information communication terminal 42 instructs the air conditioner 41, which has started to operate, to the operation mode, the set temperature, the wind direction, and other operation methods using the manual operation instruction means 66. When the environment information acquisition unit 91 does not detect a human body and the state in which the setting information is not received from the wireless communication unit 82 continues for 30 minutes (yes at step S14), the air conditioning control unit 99 of the control unit 45 stops the air conditioner 41 (step S15). When the environment information acquiring unit 91 detects a human body or receives setting information or the like from the wireless communication unit 82 (no at step S14), it determines again the detection of a human body and the reception state of the setting information (step S14). In this way, the control unit 45 acquires information from both the infrared sensor module 44 and the wireless communication module 43, thereby recognizing the presence or absence of the user with high accuracy.

According to embodiment 1, the control unit 45 controls the plurality of air conditioners 41 performing air conditioning corresponding to each of the plurality of air-conditioning areas 31 based on the setting information communicated via the wireless communication module 43. Therefore, each air conditioner 41 operates according to the setting information input to the information communication terminal 42. Therefore, the air conditioning system 1 performs only a necessary amount of air conditioning, and is therefore advantageous for energy saving.

Further, according to embodiment 1, the control unit 45 controls the plurality of air conditioners 41 based on manual operation setting information indicating an operation method for operating the air conditioners 41 when an input is made from the information communication terminal 42. Therefore, each air conditioner 41 operates according to the manual operation setting information input to the information communication terminal 42. Therefore, the air conditioner 41 of the air conditioning system 1 is operated using the information communication terminal 42, and thus the convenience is improved.

Further, according to embodiment 1, when the set air conditioner 41 is stopped, the control unit 45 controls the plurality of air conditioners 41 based on the automatic operation start condition information for determining whether or not to start the operation of the air conditioner 41. Therefore, each air conditioner 41 operates based on the automatic operation start condition information input to the information communication terminal 42. Therefore, the air conditioning system 1 does not operate the air conditioner 41 when air conditioning is not required, so that it is advantageous for energy saving.

In addition, according to embodiment 1, the air conditioning system 1 includes an infrared sensor module 44 that detects infrared rays. Therefore, the control unit 45 acquires information from both the infrared sensor module 44 and the wireless communication module 43, thereby identifying the presence or absence of the user with high accuracy. Therefore, the air conditioning system 1 stops the air conditioner 41 without requiring the air conditioner 41, which is more advantageous for energy saving.

Further, according to embodiment 1, the air conditioning system 1 includes a single infrared sensor module 44 that detects infrared rays in all the detection regions 33. Therefore, errors are less likely to occur in the temperatures detected in the respective regions. Therefore, the air conditioner 41 of the air conditioning system 1 performs air conditioning based on accurate measurement of the indoor temperature distribution, and thus can improve the comfort of the user.

Further, according to embodiment 1, the infrared sensor module 44 is attached to the ceiling 23 using the plate spring 28. In general, since the ceiling 23 to which the infrared sensor module 44 is attached is narrow, it is difficult to secure a sufficient space for attaching the infrared sensor module 44. Generally, the leaf spring 28 is thinner and lighter in construction than the infrared sensor module 44. Therefore, as in embodiment 1, the plate spring 28 is less likely to interfere with the work even when used for mounting the infrared sensor module 44, and a reduction in workability when mounting the infrared sensor module 44 can be suppressed.

Further, according to embodiment 1, the infrared sensor module 44 and the control unit 45 are separate bodies. In general, since the ceiling 23 to which the infrared sensor module 44 is attached is narrow, it is difficult to secure a sufficient space for attaching the infrared sensor module 44. The control unit 45 is connected to the respective air conditioners 41, a power supply, an external input/output terminal, and the like. That is, when the infrared sensor module 44 is integrated with the control unit 45 and needs to be mounted at the same time, the space for mounting the infrared sensor module 44 is further limited, and thus the workability is lowered. Therefore, as in embodiment 1, by providing the infrared sensor module 44 and the control unit 45 separately, it is possible to suppress a reduction in workability.

According to embodiment 1, the control unit 45 may be connected to an external server. The control unit 45 transmits the operation information of the air conditioner 41, the information obtained from the information communication terminal 42, and the information obtained from the infrared sensor module 44 to an external server. Thus, by using the air conditioning system 1, the control unit 45 stores information such as the presence or absence of a user in each time zone in the air-conditioning target room 11 and information such as the setting of the operation of the air conditioner 41 in the external server. Therefore, by connecting the control unit 45 to the external server, the operation of other devices using the information of the external server can be made efficient.

Embodiment mode 2

Fig. 14 is a schematic diagram showing an air conditioning system 101 according to embodiment 2. Embodiment 2 is different from embodiment 1 in that the air conditioning system 101 does not include the infrared sensor module 44. In embodiment 2, the same portions as those in embodiment 1 are denoted by the same reference numerals, and description thereof is omitted, and differences from embodiment 1 will be described.

As shown in fig. 13, the air conditioning system 101 does not have the infrared sensor module 44. Even in this case, the control unit 45 controls the plurality of air conditioners 41 that perform air conditioning corresponding to each of the plurality of air-conditioning areas 31, based on the setting information communicated via the wireless communication module 43.

According to embodiment 2, the control unit 45 controls the plurality of air conditioners 41 that perform air conditioning corresponding to each of the plurality of air-conditioning areas 31, based on the setting information communicated via the wireless communication module 43. Therefore, each air conditioner 41 operates according to the setting information input to the information communication terminal 42. Therefore, the air conditioning system 101 performs only a necessary amount of air conditioning, and is therefore advantageous for energy saving.

Embodiment 3

Fig. 15 is a schematic diagram showing an air conditioning system 201 according to embodiment 3. The present embodiment 3 is different from embodiment 1 in that the air conditioning system 201 does not include the wireless communication module 43. In embodiment 3, the same portions as those in embodiment 1 are denoted by the same reference numerals, and description thereof is omitted, and differences from embodiment 1 will be described.

As shown in fig. 15, the air conditioning system 201 does not have the wireless communication module 43. Even in this case, the control unit 45 controls the plurality of air conditioners 41 that perform air conditioning corresponding to each of the plurality of air-conditioning areas 31, based on only the detection result of the infrared sensor module 44 having the single infrared sensor 72 that detects the temperature.

(operation of the control section 45)

Next, the operation of the control unit 45 that receives the operation instruction from the information communication terminal 42 will be described in detail, which is different from embodiment 1. When the state in which the environment information acquisition unit 91 does not detect the position of the human body continues for 1 hour, the control unit 45 stops the air conditioner 41 by the air conditioning control unit 99 of the control unit 45. The duration of the state in which the position of the human body is not detected may also be set to less than 1 hour or more than 1 hour.

According to embodiment 3, the control unit 45 includes the single infrared sensor module 44 that detects infrared rays in all the detection regions 33. Therefore, an error is less likely to occur in the temperature detected in each detection region 33. Therefore, the air conditioner 41 of the air conditioning system 201 performs air conditioning based on accurate measurement of the indoor temperature distribution, and thus the comfort of the user can be improved.
