Description

Air conditioning system

Technical Field

The present disclosure relates to an air conditioning system having an air blowing device provided in an indoor space.

Background

In the case where an air conditioning system is to be controlled in a wide indoor space such as an office, it is difficult to eliminate temperature unevenness in the indoor space.

In a conventional air conditioning system, a temperature sensor is mounted on each personal computer on a desk used by a householder (see, for example, patent document 1). The temperature sensor detects the temperature of the face or the temperature of the fingertips of a person in the room. In addition, a separate fan for blowing air to each person in the room is attached to the personal computer. In a control unit of an air conditioning system, a face temperature or a fingertip temperature, which is comfortable for a person in a room, is stored in advance as a neutral temperature. The control unit controls the operation of the individual fan based on the deviation between the temperature detection value of each temperature sensor and the neutral temperature sensing temperature.

However, in the conventional air conditioning system described in patent document 1, the control unit blows air to each occupant by a separate fan based on the face temperature or the fingertip temperature that each occupant feels comfortable. Therefore, comfort can be provided to each occupant, but there is a problem that temperature unevenness in the entire indoor space cannot be eliminated.

Detailed Description

Hereinafter, embodiments of the air conditioning system according to the present disclosure will be described with reference to the drawings. The present disclosure is not limited to the following embodiments, and various modifications can be made without departing from the scope of the present disclosure. The present disclosure includes all combinations of combinable configurations among the configurations shown in the following embodiments and modifications thereof. Note that, in the drawings, the same or corresponding portions are denoted by the same reference numerals, and this is common throughout the specification. In addition, the relative dimensional relationship, shapes, and the like of the respective constituent members may be different from actual ones in each drawing.

Embodiment 1.

Fig. 1 is a schematic block diagram showing the configuration of an air conditioning system according to embodiment 1. As shown in fig. 1, the air conditioning system includes: a remote controller 1, a temperature detection device 2, an air blowing device 3, an indoor unit 4, and an outdoor unit 5. An air conditioning system performs air conditioning of a target indoor space. The indoor space is, for example, a restaurant.

The remote controller 1 is electrically connected to the indoor unit 4 via a communication wiring 7a. The user inputs setting information such as a set temperature, a wind direction, a wind speed, and an operation mode for the indoor space to the remote controller 1. The user is here, for example, a clerk of a restaurant. The operation modes include at least an operation mode of a cooling operation and an operation mode of a heating operation. The remote controller 1 generates a first control signal based on the setting information and transmits the first control signal to the indoor unit 4 via the communication wiring 7a. The communication between the remote controller 1 and the indoor unit 4 is wired communication using the communication wiring 7a. Further, the indoor unit 4 is electrically connected to the outdoor unit 5 via a communication wiring 7b. At least a part of the first control signal input to the remote controller 1 is transmitted to the outdoor unit 5 via the indoor unit 4 and the communication wiring 7b. The communication between the indoor unit 4 and the outdoor unit 5 is wired communication using the communication wiring 7b. The communication between the indoor unit 4 and the outdoor unit 5 is not limited to this case, and may be wireless communication.

The temperature detection device 2 detects the temperature of the air of the indoor space. As shown in fig. 4 described later, the indoor space includes a plurality of regions A, B and C. The temperature detection device 2 detects the temperature of each of the plurality of regions A, B and C. The temperature detection device 2 may be any temperature sensor capable of detecting the room temperature of each region of the indoor space, and is, for example, a digital temperature sensor. When the temperature detection device 2 is a digital temperature sensor, the temperature detection devices 2 are provided in the plurality of regions A, B and C, respectively. Therefore, the number of the temperature detection devices 2 is plural. As the temperature detection device 2, an infrared sensor such as a thermopile sensor may be used. In this case, since the temperature detection device 2 can monitor the entire indoor space, the temperatures of the plurality of regions A, B and C can be detected by one temperature detection device 2. In this case, the remote controller 1 detects the temperatures of the plurality of areas A, B and C based on the colors in the two-dimensional image data captured by the infrared sensor. In this way, the number of the temperature detection devices 2 may be one or plural. The plurality of regions A, B and C are not partitioned by a wall or the like, but communicate with each other. The plurality of regions A, B and C are set in advance based on, for example, the range in which the temperature detection device 2 can detect the temperature. The number of regions in which the temperature detection device 2 detects temperature may be 2 or more. That is, the number of the regions may be appropriately determined according to the size, structure, and the like of the indoor space. The temperature detection device 2 transmits the detected temperatures of the respective areas A, B and C to the remote controller 1 via the wireless communication line 6a. The communication between the temperature detection device 2 and the remote controller 1 is wireless communication. Examples of the communication method of the wireless communication include BlueTooth (registered trademark), BLE (registered trademark), and Wi-Fi.

The air blowing device 3 blows air to each of the plurality of regions A, B and C. The blower 3 is, for example, an axial fan including a propeller fan and a motor. The blower 3 sends air in a direction parallel to the axial direction. The blower 3 may be provided inside or outside each of the regions A, B and C. The blower 3 may be a wall-mounted type installed on a wall surface of the indoor space, or a floor-mounted type installed on a floor surface of the indoor space. The air blowing device 3 is controlled by the remote controller 1. The second control signal is transmitted from the remote controller to the air blowing device 3 via the wireless communication line 6b. The blower 3 is switched between operation and stop in response to the second control signal. The blower 3 may control the wind direction, the air volume, and the like based on the second control signal. The communication between the air blowing device 3 and the remote controller 1 is wireless communication. The communication method of the wireless communication is, for example, BlueTooth (registered trademark), BLE, or Wi-Fi.

The indoor unit 4 is provided in an indoor space. The outdoor unit 5 is installed outdoors. Fig. 2 is a refrigerant circuit diagram showing the configurations of the indoor unit 4 and the outdoor unit 5 of the air conditioning system according to embodiment 1. As shown in fig. 2, the indoor unit 4 is connected to the outdoor unit 5 by a refrigerant pipe 60.

As shown in fig. 2, the indoor unit 4 includes an indoor-side heat exchanger 41. The indoor-side heat exchanger 41 performs heat exchange between the refrigerant flowing through the inside and the air in the indoor space. The indoor-side heat exchanger 41 is, for example, a fin-tube heat exchanger. The indoor-side heat exchanger 41 functions as a condenser when the air conditioning system is in a heating operation, and functions as an evaporator when the air conditioning system is in a cooling operation.

As shown in fig. 2, the outdoor unit 5 includes an outdoor heat exchanger 51, a compressor 52, a flow path switching device 53, an expansion valve 54, and a controller 55. The outdoor unit 5 may further include other components such as an accumulator.

The outdoor heat exchanger 51 performs heat exchange between the refrigerant flowing through the inside and outdoor air. The outdoor heat exchanger 51 is, for example, a fin-tube heat exchanger. The outdoor heat exchanger 51 functions as a condenser when the air conditioning system is in the cooling operation, and functions as an evaporator when the air conditioning system is in the heating operation.

The compressor 52 sucks and compresses a low-pressure gas refrigerant, and discharges the refrigerant as a high-pressure gas refrigerant. As the compressor 52, for example, an inverter compressor that can change the amount of refrigerant sent per unit time by control of an inverter circuit or the like can be used. In this case, the inverter circuit is mounted on the control unit 55, for example, or is communicably connected to the control unit 55 and controlled by the control unit 55.

The expansion valve 54 reduces the pressure of the liquid refrigerant flowing in by a throttling action and flows out, so that the refrigerant liquefied in the condenser is easily evaporated in the evaporator. In addition, the expansion valve 54 adjusts the amount of refrigerant so as to maintain an appropriate amount of refrigerant corresponding to the load of the evaporator. The expansion valve 54 is constituted by an electronic expansion valve, for example. The opening degree of the expansion valve 54 is controlled by the controller 55. As shown in fig. 2, the expansion valve 54 is connected between the outdoor heat exchanger 51 and the indoor heat exchanger 41 by a refrigerant pipe 60.

The flow path switching device 53 is a valve for switching the direction of the flow of the refrigerant. The flow path switching device 53 is constituted by a four-way valve, for example. The flow path switching device 53 switches between the case where the air conditioning system is in the cooling operation and the case where the air conditioning system is in the heating operation under the control of the control unit 55. When the air conditioning system is in the cooling operation, the flow switching device 53 is in the state shown by the solid line in fig. 2, and the refrigerant discharged from the compressor 52 flows into the outdoor heat exchanger 51. During the heating operation, the flow switching device 53 is in a state shown by a broken line in fig. 2, and the refrigerant discharged from the compressor 52 flows into the indoor-side heat exchanger 41 of the indoor unit 4.

As shown in fig. 2, the refrigerant pipe 60 connects the compressor 52, the flow switching device 53, the outdoor heat exchanger 51, the expansion valve 54, and the indoor heat exchanger 41 to constitute a refrigerant circuit.

The first wireless communication unit 12 receives the temperature detected by the temperature detection device 2 from the temperature detection device 2 via the wireless communication line 6a. The first wireless communication unit 12 transmits a second control signal, which will be described later, generated by the first control unit 11 to the air blower 3 via the wireless communication line 6b. The first wireless communication unit 12 is configured by, for example, a transmission/reception antenna and a signal processing circuit that processes a transmission signal and a reception signal.

The first operation unit 15 is operated by a user to input setting information such as a set temperature, a wind direction, an air volume, and an operation mode for an indoor space. The first operation unit 15 is constituted by, for example, a plurality of mechanical buttons and switches provided on the surface of the remote controller 1. The first operation unit 15 is not limited to this case, and any user interface may be applied as long as it can receive an instruction from a user.

The first display unit 16 displays setting information input to the first operation unit 15. The first display unit 16 may display the temperature of each region detected by the temperature detection device 2. The first display unit 16 is constituted by a liquid crystal screen, for example. The plurality of buttons and switches constituting the first operation unit 15 may be constituted by virtual buttons displayed on the screen of the first display unit 16. In this case, the first operation unit 15 and the first display unit 16 are integrated, and are formed of, for example, a touch panel.

The first control unit 11 controls the operation of the entire remote controller 1. The first control unit 11 generates a first control signal for controlling the indoor unit 4 and the outdoor unit 5 based on the setting information input to the first operation unit 15. Alternatively, the first control unit 11 generates the first control signal based on the temperature received by the first wireless communication unit 12 from the temperature detection device 2. The first control unit 11 generates a second control signal for controlling the air blowing device 3 based on the temperature received by the first wireless communication unit 12 from the temperature detection device 2.

The processing Circuit is configured by dedicated hardware such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array), or an arithmetic device such as a processor that executes a program stored in a memory constituting the first storage unit 14, or both.

The first wired communication unit 13 transmits the first control signal generated by the first control unit 11 to the indoor unit 4 via the communication wiring 7a. Further, a part of the first control signal is transmitted from the indoor unit 4 to the outdoor unit 5 via the communication wiring 7b. The first wired communication unit 13 is configured by, for example, a signal processing circuit that processes a transmission signal and an interface circuit connected to the communication wiring 7a. The first wired communication unit 13 may have a function of receiving various signals such as failure information and outdoor air temperature from the indoor unit 4 and the outdoor unit 5.

The first storage unit 14 stores the calculation result of the first control unit 11. The operation result includes control information such as a first control signal and a second control signal. The first storage unit 14 stores the temperature of each area received by the first wireless communication unit 12 from the temperature detection device 2. The stored temperature may be time-series data or may be only the latest temperature. The first storage unit 14 stores setting information input to the first operation unit 15. The first storage unit 14 is formed of a memory. The Memory is constituted by a nonvolatile or volatile semiconductor Memory such as a RAM (Random Access Memory), a ROM (Read Only Memory), a flash Memory, a magnetic disk, a flexible disk, or the like.

As shown in fig. 1, the temperature detection device 2 includes a second control unit 21, a temperature detection unit 22, and a second wireless communication unit 23.

The second control unit 21 controls the operation of the entire temperature detection device 2. The second control unit 21 controls the operations of the temperature detection unit 22 and the second wireless communication unit 23.

The temperature detection unit 22 detects the temperature of each region of the indoor space. When the temperature detection device 2 is an infrared sensor, the temperature detection unit 22 includes a sensor element such as an infrared light receiving element that contactlessly measures the temperature of the object. However, the temperature detection unit 22 is not limited to this case. For example, when the temperature detection device 2 is a digital thermometer, the temperature detection unit 22 may include a semiconductor element such as a thermistor whose resistance value changes in accordance with a temperature change, or a thermoelectric element whose electromotive force changes in accordance with a temperature change.

The second wireless communication unit 23 transmits the temperature detected by the temperature detection unit 22 to the first wireless communication unit 12 of the remote controller 1 via the wireless communication line 6a. The second wireless communication unit 23 is configured by, for example, a transmission/reception antenna and a signal processing circuit that processes a transmission signal and a reception signal.

As shown in fig. 1, the air blowing device 3 includes a third control unit 31, an air blowing unit 32, and a third wireless communication unit 33.

The third wireless communication unit 33 receives the second control signal from the first wireless communication unit 12 of the remote controller 1. The third wireless communication section 33 transmits the received second control signal to the third control section 31. The third wireless communication unit 33 is configured by, for example, a transmission/reception antenna and a signal processing circuit that processes a transmission signal and a reception signal.

The third control unit 31 controls the rotational speed of the motor of the blowing unit 32 based on the second control signal received from the remote controller 1.

Fig. 3 is a configuration diagram showing the overall configuration of the air conditioning system according to embodiment 1. Fig. 4 is a diagram schematically showing an example of the state of an indoor space in which the air conditioning system according to embodiment 1 is installed. Fig. 4 is a side view of the indoor space.

As shown in fig. 3, the air conditioning system includes a plurality of air blowing devices 3 and a plurality of temperature detection devices 2. In order to distinguish each of the plurality of air blowing devices 3, the plurality of air blowing devices 3 are respectively referred to as an air blowing device 3a, an air blowing device 3b, and an air blowing device 3c in fig. 3 and 4. In order to distinguish the plurality of temperature detection devices from each other, the plurality of temperature detection devices 2 are respectively referred to as a temperature detection device 2a, a temperature detection device 2b, and a temperature detection device 2c in fig. 3 and 4.

As shown in fig. 3, the temperature detection device 2a, the temperature detection device 2b, and the temperature detection device 2c are each wirelessly communicated with the remote controller 1 via a wireless communication line 6a. The air blowing devices 3a, 3b, and 3c wirelessly communicate with the remote controller 1 via wireless communication lines 6b, respectively.

As shown in fig. 4, when the indoor space is box-shaped, the indoor space is a space defined by a ceiling, a floor, and 4 wall surfaces arranged between the ceiling and the floor. As described above, a plurality of regions A, B and C are set in advance in the indoor space.

As shown in fig. 4, the remote controller 1 is disposed in the indoor space. In fig. 4, the remote controller 1 is disposed on a wall surface of an indoor space. The communication between the remote controller 1 and the indoor unit 4 may be wireless communication, and the remote controller 1 may be detachable from the wall surface in the room. In addition, an indoor unit 4 is mounted on the ceiling of the indoor space.

In addition, a plurality of tables 8a, 8b, and 8c are provided on the floor of the indoor space. The area where the table 8a is provided is an area a. The area where the table 8B is provided is an area B. The area where the table 8C is provided is an area C.

In the example of fig. 4, person 9a is present on table 8a, and person 9c is present on table 8c. The persons 9a and 9c are customers of the restaurant.

Further, the temperature detection device 2a is disposed in the area a, the temperature detection device 2B is disposed in the area B, and the temperature detection device 2C is disposed in the area C. The temperature detection devices 2a, 2b, and 2c may be disposed on the respective tables 8a, 8b, and 8c. Alternatively, the temperature detection devices 2a, 2b, and 2c may be disposed on the respective side surfaces of the tables 8a, 8b, and 8c. The temperature detection means 2a detects the temperature of the air of the area a, the temperature detection means 2B detects the temperature of the air of the area B, and the temperature detection means 2C detects the temperature of the air of the area C.

Air blowing devices 3a, 3B, and 3C are disposed in the area a, the area B, and the area C, respectively. The air blowing devices 3a, 3b, and 3c may be disposed on the tables 8a, 8b, and 8c, or may be disposed so as to face a part of the outer peripheries of the tables 8a, 8b, and 8c. Air blowing device 3a blows air to area a, air blowing device 3B blows air to area B, and air blowing device 3C blows air to area C.

Next, the operation of the air conditioning system according to embodiment 1 will be described. The air conditioning system configured as described above operates based on the setting information input by the user to the remote controller 1 during normal operation.

For example, a case will be described in which at least one of the 3 temperature detection devices 2a, 2b, and 2c detects a temperature exceeding a first threshold value set in advance in the indoor space shown in fig. 4.

In the following description, the temperature detection means that detects a temperature exceeding the first threshold value is referred to as "exceeding threshold value temperature detection means". Here, the first threshold is a fixed value, for example, 26 ℃. The first threshold is not limited to this value, and may be changed as appropriate depending on the season, outdoor temperature, and the like.

The first threshold value may be variable. Specifically, the first threshold value may be updated based on the set temperature of the indoor unit 4. In this case, for example, a value higher than the set temperature of the indoor unit 4 by a certain temperature is set as the first threshold value. If the set temperature is 24 ℃ and the constant temperature is 2 ℃, the first threshold value becomes 26 ℃. In this case, when the temperature detected by the temperature detection device 2 is not lower than a predetermined temperature (2 ℃) from the set temperature, the first control unit 11 drives the air blowing device 3.

Fig. 5 is a side view showing a case where at least one of the 3 temperature detection devices 2a, 2b, and 2c detects a temperature exceeding a first threshold value in the air conditioning system according to embodiment 1. In the example of fig. 5, a case is shown where the temperature of the air in the area C detected by the temperature detection device 2C exceeds the first threshold value. That is, the temperature detection device 2c is an "over-threshold temperature detection device". On the other hand, the temperatures of the air in the areas a and B detected by the temperature detection devices 2a and 2B are equal to or lower than the first threshold value. Therefore, the temperature detection devices 2a and 2b are not "over threshold temperature detection devices". At this time, the first control unit 11 of the remote controller 1 acquires the temperatures detected by the temperature detection devices 2a, 2b, and 2c, and determines the presence or absence of the "exceeding threshold temperature detection device" based on these temperatures. Here, the temperature detection device 2c is an "over-threshold temperature detection device". The first control unit 11 generates the second control signal for the air blowing device 3c corresponding to the temperature detection device 2c with reference to the relational table 100 shown in fig. 6. Thereby, the blower 3c starts operating. Fig. 6 is a diagram showing an example of a relationship table 100 defining a correspondence relationship between temperature detection devices and air blowing devices in the air conditioning system according to embodiment 1. As shown in fig. 6, the relationship table 100 registers in advance the correspondence relationship between the first identification information of the temperature detection devices 2a, 2b, and 2C and the second identification information of the air blowing devices 3a, 3b, and 3C for each of the regions A, B and C. The relationship table 100 is stored in advance in the first storage unit 14 of the remote controller 1. The first identification information is unique identification information for identifying each of the temperature detection devices 2a, 2b, and 2c, and the second identification information is unique identification information for identifying each of the air blowing devices 3a, 3b, and 3c.

The first control unit 11 of the remote controller 1 counts the time from the start of the operation of the air blowing device 3c corresponding to the "exceeding threshold temperature detection device". The first control unit 11 generates the second control signal for stopping the operation of the air blower 3c when all the temperatures detected by the temperature detection devices 2a, 2b, and 2c are equal to or lower than the first threshold value continuously for the first time period. Thereby, the blower 3c stops operating. The first time is, for example, 5 minutes. However, the first time is not limited to 5 minutes, and may be appropriately determined. In the following description, for the sake of simplicity of description, a case where the first time is set to 5 minutes will be described as an example.

Fig. 7 is a flowchart showing a flow of processing of the remote controller 1 of the air conditioning system according to embodiment 1.

As shown in fig. 7, in step S1, the first control unit 11 of the remote controller 1 acquires the temperatures detected by the temperature detection devices 2a, 2b, and 2c, respectively.

Next, in step S2, the first control unit 11 determines whether or not there is "excess threshold temperature detection means" based on the temperatures detected by the temperature detection devices 2a, 2b, and 2c, respectively. If "exceeding threshold temperature detecting means" is present, the process proceeds to step S3. Here, it is assumed that the bit temperature detection means 2c is "excess threshold temperature detection means". On the other hand, if there is no "exceeding threshold temperature detection means", the flow proceeds to step S4.

In step S3, the first control unit 11 extracts the blower device 3c corresponding to the temperature detection device 2c from the relationship table 100 shown in fig. 6. The first control unit 11 transmits a second control signal to the air blowing device 3c to operate the air blowing device 3c. Then, the process returns to step S1.

In step S4, it is determined whether or not there is an operating air blower among the air blowers 3a, 3b, and 3c. If there is no air blower in operation, the process proceeds to step S7. On the other hand, if there is an air blower in operation, the process proceeds to step S5.

In step S5, the first control unit 11 determines whether or not 5 minutes has elapsed from the start of the operation of the air blowing device 3c in step S3. When 5 minutes have elapsed, the process proceeds to step S6. On the other hand, if 5 minutes have not elapsed, the process returns to step S1.

In step S6, the first control unit 11 stops the air blowing device 3c in operation. Then, the process proceeds to step S7.

In step S7, the first control unit 11 changes the state of the air conditioning system and shifts to a normal operation.

As described above, in embodiment 1, the first control unit 11 of the remote controller 1 determines whether or not there is a region in which the detected temperature exceeds the first threshold value, based on the temperatures detected by the temperature detection devices 2a, 2b, and 2c. As a result of the determination, when the temperature of the area C exceeds the first threshold value, the first control unit 11 drives the air blowing device 3C provided in the area C. Then, the first control unit 11 acquires the temperatures detected by the temperature detection devices 2a, 2b, and 2c again. When the state in which the temperatures of all the regions A, B and C are equal to or lower than the first threshold value continues for 5 minutes, the first control unit 11 sets all the air blowing devices 3a, 3b, and 3C to the stopped state. This eliminates the temperature unevenness in the indoor space. As a result, since there is no locally hot area or locally cold area, comfort can be provided to all occupants in the indoor space.

In embodiment 1, the blower 3c can be automatically operated under the control of the first control unit 11. Therefore, the occupants 9a and 9C in the respective areas A, B and C can blow air to the area C without operating the remote controller 1 and the air blowing devices 3a, 3b, and 3C. Therefore, there is no workload on the persons 9a and 9c.

As described above, in embodiment 1, when there is at least one excess threshold temperature detection device whose temperature exceeds the first threshold, the air blowing device blows air to the area corresponding to the excess threshold temperature detection device. Thereby, the temperature of the region is decreased. As a result, the temperature of all the regions can be set to the first threshold value or less. Therefore, temperature unevenness in the indoor space is eliminated.

Further, convection is generated in the indoor space by blowing air to the region corresponding to the excess threshold temperature detection device by the air blowing device. Thus, since the air having a high temperature and the air having a low temperature are forcibly mixed, the temperature unevenness in the indoor space is promptly eliminated. As a result, the temperature of the indoor space quickly reaches the set temperature, and thus cooling or heating can be efficiently performed. Therefore, the power consumed by the air conditioning system can be reduced, and an energy saving effect can be obtained.

Embodiment 2.

In embodiment 1, the description has been given of an embodiment in which the first control unit 11 operates the air blowing devices 3a, 3b, and 3c corresponding to the "excess threshold temperature detection device" when the "excess threshold temperature detection device" is present. Hereinafter, the process flow of embodiment 1 shown in fig. 7 will be referred to as "blower operation process flow". In embodiment 2, when there is the "exceeding threshold temperature detecting device", the first control unit 11 operates the air blowing devices 3a, 3b, and 3c and also controls the indoor unit 4. Hereinafter, the processing flow of embodiment 2 shown in fig. 9 to be described later will be referred to as "blower + indoor-unit operation processing flow".

Fig. 8 is a side view showing a case where at least one of the 3 temperature detection devices 2a, 2b, and 2c detects a temperature exceeding a first threshold value in the air conditioning system according to embodiment 2. In the example of fig. 8, the case where the temperatures of the air in the area a and the area C detected by the temperature detection devices 2a and 2C exceed the first threshold value is shown.

That is, in the example of fig. 8, the temperature detection devices 2a and 2c are "over-threshold temperature detection devices" in the indoor space. In this case, the first control unit 11 of the remote controller 1 operates the air blowing devices 3a and 3c corresponding to the temperature detection devices 2a and 2c with reference to the relational table 100 of fig. 6.

In embodiment 2, when the rate of "exceeding the threshold temperature detection device" is 50% or more of the total, the first control unit 11 of the remote controller 1 controls the indoor unit 4. Specifically, the first control unit 11 of the remote controller 1 generates, as the first control signal, a command for lowering the set temperature of the indoor unit 4 by a predetermined constant value. The indoor unit 4 lowers the set temperature of the indoor unit 4 by a predetermined value in accordance with the first control signal. The predetermined value is set to 0.5 ℃ or 1 ℃ in advance, for example, and is set in advance in either the indoor unit 4 or the remote controller 1.

In the example of fig. 8, the temperature detection devices 2a and 2c are "over-threshold temperature detection devices". That is, the number of "exceeding threshold temperature detecting means" is 2. The number of the entire temperature detection devices 2 is 3. Therefore, the percentage of the number of "over threshold temperature detection devices" is currently 50% or more of the total. Therefore, the first control unit 11 of the remote controller 1 generates the first control signal for lowering the set temperature of the indoor unit 4 by a predetermined value.

Then, when the temperature detected by the temperature detection devices 2a, 2b, and 2c is lower than the first threshold value for 5 minutes, the first control unit 11 of the remote controller 1 restores the set temperature of the indoor unit 4. The first control unit 11 of the remote controller 1 stops the air blowing devices 3a and 3c.

Fig. 9 is a flowchart showing a flow of processing of the remote controller 1 of the air conditioning system according to embodiment 2.

As shown in fig. 9, in step S10, the first control unit 11 of the remote controller 1 acquires the temperatures detected by the temperature detection devices 2a, 2b, and 2c, respectively.

Next, in step S11, the first control unit 11 determines whether or not there is an "over threshold temperature detection means" among the temperature detection means 2a, 2b, and 2c. If "exceeding threshold temperature detecting means" is present, the process proceeds to step S12. Here, the temperature detection devices 2a and 2c are assumed to be "over-threshold temperature detection devices". On the other hand, if there is no "exceeding threshold temperature detection means", the flow proceeds to step S16.

In step S12, the first control unit 11 extracts the air blowing devices 3a and 3c corresponding to the temperature detection devices 2a and 2c from the relationship table 100 shown in fig. 6. The first control unit 11 transmits a second control signal to the air blowing devices 3a and 3c to operate the air blowing devices 3a and 3c. Then, the process proceeds to step S13.

In step S13, the first control unit 11 determines whether or not the percentage of the number of "exceeding threshold temperature detection devices" is 50% or more of the total. If the ratio is 50% or more, the process proceeds to step S14. On the other hand, if the ratio is less than 50%, the process proceeds to step S15.

In step S14, the first control unit 11 lowers the set temperature of the indoor unit 4 by a predetermined value. Then, the process returns to step S10.

In step S15, the first control unit 11 changes the state of the air conditioning system, and the flow proceeds to the blower operation flow shown in fig. 7 in embodiment 1. At this time, when the set temperature of the indoor unit 4 is lowered in step S14, the first control unit 11 restores the set temperature of the indoor unit 4.

In step S16, it is determined whether or not there is an active air blowing device 3 among the air blowing devices 3a, 3b, and 3c. If there is no air blower 3 in operation, the process proceeds to step S20. On the other hand, if there is an air blower 3 in operation, the process proceeds to step S17.

In step S17, the first control unit 11 determines whether or not 5 minutes have elapsed from the time when the operation of the air blowing device 3 was started in step S12. When 5 minutes have elapsed, the process proceeds to step S18. On the other hand, if 5 minutes have not elapsed, the process returns to step S10.

In step S18, the first control unit 11 restores the set temperature of the indoor unit 4. Then, the process proceeds to step S19.

In step S19, the first control unit 11 stops the air blowing device 3c in operation. Then, the process proceeds to step S20.

In step S20, the first control unit 11 changes the state of the air conditioning system and shifts to a normal operation.

As described above, in embodiment 2, similarly to embodiment 1, when there is the "excess threshold temperature detection device", the first control unit 11 operates the air blowing devices 3a, 3b, and 3c corresponding to the "excess threshold temperature detection device". Therefore, the same effect as embodiment 1 is obtained.

In embodiment 2, when the ratio of the number of "exceeding threshold temperature detection devices" is 50% or more of the total, the first control unit 11 controls the set temperature of the indoor unit 4 in addition to operating the air blowing devices 3a, 3b, and 3c. Therefore, the temperature of the indoor space can be quickly set to the set temperature desired by the user while eliminating the temperature unevenness of the indoor space.

Embodiment 3.

In embodiment 3, an embodiment in which the above-described embodiments 1 and 2 are combined will be described. Fig. 10 is a state transition diagram showing state transition of the air conditioning system according to embodiment 3.

As shown in fig. 10, the air conditioning system has 3 states, namely, a normal operation state 70, an air blowing device operation state 71, and an air blowing device + indoor unit operation state 72, and transitions between these states.

The normal operation state 70 is a state in which the air conditioning system is normally operated. In the normal operation state 70, the air conditioning system operates based on the setting information input by the user to the remote controller 1.

The blower operation state 71 is a state in which the air conditioning system operates according to the blower operation flow shown in embodiment 1 shown in fig. 7.

The blower + indoor unit operation state 72 is a state in which the air conditioning system operates according to the blower + indoor unit operation flow shown in embodiment 2 shown in fig. 9.

The air conditioning system is in a normal operating state 70.

When the proportion of the number of "exceeding threshold temperature detection devices" is 50% or more of the total number in the normal operation state 70 of the air conditioning system, the air conditioning system shifts to the blower + indoor unit operation state 72.

If the air conditioning system is in the normal operation state 70 and has at least one "excess threshold temperature detection device" and the ratio of the number of "excess threshold temperature detection devices" is less than 50% of the total, the air conditioning system transitions to the blower operation state 71.

When the percentage of the number of "exceeding threshold temperature detection devices" is 50% or more of the total number when the air conditioning system is in the blower operation state 71, the air conditioning system transitions to the blower + indoor unit operation state 72.

If there is no "over-threshold-temperature detection device" in the air-conditioning system in the blower operating state 71, the air-conditioning system transitions to the normal operating state 70.

If there is no "exceeding threshold temperature detection device" in the case where the air conditioning system is in the blower + indoor unit operating state 72, the air conditioning system transitions to the normal operating state 70.

Fig. 11 is a flowchart showing a flow of processing of the remote controller 1 of the air conditioning system according to embodiment 3. Hereinafter, the process flow of embodiment 3 shown in fig. 11 is referred to as a "normal operation process flow".

As shown in fig. 11, in step S21, the first control unit 11 of the remote controller 1 acquires the temperatures detected by the temperature detection devices 2a, 2b, and 2c, respectively.

Next, in step S22, the first control unit 11 determines whether or not there is an "over-threshold temperature detection means" among the temperature detection means 2a, 2b, and 2c. If "exceeding threshold temperature detecting means" is present, the process proceeds to step S23. It is assumed here that the detected temperature of the temperature detection device 2a exceeds the first threshold value. On the other hand, if there is no "exceeding threshold temperature detection means", the flow proceeds to step S28.

In step S23, the first control unit 11 extracts the blower 3a corresponding to the temperature detection device 2a from the relational table 100 shown in fig. 6. The first control unit 11 transmits a second control signal to the air blowing device 3a to operate the air blowing device 3a. Then, the process proceeds to step S24.

In step S24, the first control unit 11 determines whether or not the percentage of the number of "exceeding threshold temperature detection devices" is 50% or more. If the ratio is 50% or more, the process proceeds to step S25. On the other hand, if the ratio is less than 50%, the process proceeds to step S27.

In step S25, the first control unit 11 lowers the set temperature of the indoor unit 4 by a predetermined constant value. Then, the process proceeds to step S26.

In step S26, the first control unit 11 changes the state of the air conditioning system, and the flow proceeds to the blower + indoor unit operation process flow shown in fig. 9. However, when the process flow in fig. 9 is shifted to, the set temperature of the indoor unit 4 has already been lowered in step S25, and therefore the process of step S14 may not be performed for the first time.

In step S27, the first control unit 11 changes the state of the air conditioning system, and the flow proceeds to the blower operation processing flow of fig. 7.

In step S28, the first control unit 11 changes the state of the air conditioning system and controls the air conditioning system to perform a normal operation. During normal operation, the air conditioning system operates based on setting information input by the user to the remote controller 1.

As described above, in embodiment 3, as shown in fig. 10, the air conditioning system transitions to any one of the normal operation state 70, the blower operation state 71, and the blower + indoor unit operation state 72 depending on the situation. Thus, the first control unit 11 can control only the air blowing device 3, or can control both the air blowing device 3 and the indoor unit 4. Therefore, only necessary processing can be performed, and thus it is possible to quickly eliminate temperature unevenness in the indoor space while suppressing energy consumption.

In embodiment 3, the blower operation processing flow shown in embodiment 1 and shown in fig. 7 and the blower + indoor unit operation processing flow shown in embodiment 2 and shown in fig. 9 are performed. Therefore, the effects of embodiment 1 and the effects of embodiment 2 can also be obtained.

Embodiment 4.

Fig. 12 is a side view schematically showing an example of the indoor state in which the air conditioning system according to embodiment 4 is installed.

In embodiments 1 to 3, the presence or absence of the persons 9a and 9c is not considered, but in embodiment 4, the first control unit 11 of the remote controller 1 also considers the presence or absence of the persons 9a and 9c. That is, in embodiment 4, the first control unit 11 shifts the state of the air conditioning system based on the detected temperatures of the temperature detection devices 2a, 2b, and 2c, the ratio of the number of "exceeding threshold temperature detection devices", and the presence or absence of a person in the room. The states include a normal operation state 70, a blower operation state 71, and a blower + indoor unit operation state 72.

In embodiment 4, as shown in fig. 12, the human detection device 10 is provided for each of the regions A, B and C. The human detection device 10 detects the presence of each of the plurality of areas A, B and C. The human detection device 10 is, for example, a human sensor. In order to distinguish the plurality of human detection devices 10, in fig. 12, the plurality of human detection devices 10 are respectively referred to as a human detection device 10a, a human detection device 10b, and a human detection device 10c. The human detection device 10a detects a person present in the area a. The human detection device 10B detects a person present in the area B. The human detection device 10C detects a person present in the room in the area C. The human detection devices 10a, 10b, and 10c may be formed of infrared sensors such as thermopile sensors, for example. In this case, the first control unit 11 performs image processing on the two-dimensional image captured by the infrared sensor, and determines the presence or absence of a person in the room based on the color, size, shape, feature, and the like of the object in the image. In this case, since one infrared sensor can monitor the entire indoor space, the individual detection device 10 can detect the individual persons in the plurality of areas A, B and C. Therefore, the number of the human detection devices 10 may be one or more. The human detection devices 10a, 10b, and 10c are not limited to this case, and may be image sensors such as a CCD (Charge Coupled Device) or a CMOS (Complementary Metal-Oxide Semiconductor). In this case, the first control unit 11 performs image processing on the two-dimensional image captured by the image sensor, and determines the presence or absence of a person in the room based on the size, shape, feature, and the like of the object in the image. In this case, since one image sensor can monitor the entire indoor space, the individual detection device 10 can detect the persons present in each of the plurality of areas A, B and C. Therefore, the number of the human detection devices 10 may be one or plural.

Fig. 13 is a diagram showing an example of a second relationship table 100A defining the correspondence relationship among the temperature detection device 2, the air blowing device 3, and the human detection device 10 in the air conditioning system according to embodiment 4. As shown in fig. 13, the second relation table 100A registers the first identification information of the temperature detection devices 2a, 2b, and 2c and the second identification information of the air blowing devices 3a, 3b, and 3c in advance in association with each other for each area. As shown in fig. 13, the second relationship table 100A registers the first identification information of the temperature detection devices 2a, 2b, and 2c and the third identification information of the human detection devices 10A, 10b, and 10c in advance in association with each other for each area. The second relation table 100A is stored in advance in the first storage unit 14 of the remote controller 1. The first identification information is identification information for identifying the temperature detection devices 2a, 2b, and 2c, and the second identification information is identification information for identifying the air blowing devices 3a, 3b, and 3c. The third identification information is identification information for identifying each of the personal detection devices 10a, 10b, and 10c.

Embodiment 4 will be described below by referring to specific examples. For example, in the indoor space shown in fig. 12, all of the 3 temperature detection devices 2a, 2b, and 2c are "over-threshold temperature detection devices". Further, person detection device 10a detects person 9a in room a, and person detection device 10C detects person 9C in room C.

In this case, the first control unit 11 first acquires the detection results of the human detection devices 10a, 10b, and 10c corresponding to the "exceeding threshold temperature detection device". The first control unit 11 determines that the human detection devices 10a and 10c detect the persons 9a and 9c in the room based on the detection result. The first control unit 11 refers to the second relational table 100A, and operates the air blowing devices 3a and 3c corresponding to the human detection devices 10A and 10c.

The first control unit 11 determines whether or not the ratio of the number of "exceeding threshold temperature detection devices" is 50% or more of the total. When the proportion of the number of "exceeding threshold temperature detection devices" is 50% or more, the first control unit 11 generates a command for lowering the set temperature of the indoor unit 4 by a predetermined value, and transmits the command as a first control signal to the indoor unit 4.

Thereafter, when the detected temperature of the temperature detection devices 2a, 2b, and 2c is lower than the first threshold value for 5 consecutive minutes, the first control unit 11 restores the set temperature of the indoor unit 4. The first control unit 11 stops the air blowing devices 3a and 3c.

Fig. 14 is a state transition diagram showing state transition of the air conditioning system according to embodiment 4.

As shown in fig. 14, the air conditioning system has 3 states, namely, a normal operation state 70, an air blowing device operation state 71, and an air blowing device + indoor unit operation state 72, and transitions between these states. Since these states are described in embodiment 3, the description thereof will be omitted here.

In embodiment 4, as in embodiments 1 to 3, the air conditioning system is in the normal operation state 70 in the normal state.

When the number of "excess threshold temperature detection devices" is 50% or more of the total number and there are room users 9a and 9c in the area corresponding to the "excess threshold temperature detection device" in the normal operation state 70 of the air conditioning system, the air conditioning system shifts to the blower + indoor unit operation state 72.

In the normal operation state 70 of the air conditioning system, at least one of the temperature detection devices 2a, 2b, and 2c is the "over-threshold temperature detection device", and the percentage of the number of "over-threshold temperature detection devices" is less than 50%. At this time, if there are persons 9a and 9c in the area corresponding to the "exceeding threshold temperature detection device", the air conditioning system shifts to the blower operation state 71.

When the number of "excess threshold temperature detection devices" is 50% or more of the total number and the persons 9a and 9c exist in the area corresponding to the "excess threshold temperature detection device" in the blower device operating state 71, the air conditioning system transitions to the blower device + indoor unit operating state 72.

When the "over-threshold temperature detection means" is not present in the case where the air conditioning system is in the blower operation state 71, the air conditioning system transitions to the normal operation state 70.

In addition, when the air conditioning system is in the blower + indoor unit operating state 72, if there is no "exceeding threshold temperature detection device", the air conditioning system transitions to the normal operating state 70.

Fig. 15 is a flowchart showing a flow of processing of the remote controller 1 of the air conditioning system according to embodiment 4. Hereinafter, the process flow of embodiment 4 shown in fig. 15 is referred to as a "second normal operation process flow".

As shown in fig. 15, in step S30, the first control unit 11 of the remote controller 1 acquires the temperatures detected by the temperature detection devices 2a, 2b, and 2c, respectively.

Next, in step S31, the first control unit 11 determines whether or not there is an "exceeding threshold temperature detection device" among the temperature detection devices 2a, 2b, and 2c. If "exceeding threshold temperature detecting means" is present, the process proceeds to step S32. Here, it is assumed that the detected temperatures of the temperature detection devices 2a, 2b, and 2c exceed the first threshold value. On the other hand, if there is no "exceeding threshold temperature detection means", the flow proceeds to step S39.

In step S32, the first control unit 11 extracts the human detection devices 10A, 10b, and 10c corresponding to the temperature detection devices 2a, 2b, and 2c from the second relationship table 100A shown in fig. 13. The first control unit 11 acquires the detection results of the human detection devices 10a, 10b, and 10c. Then, the process proceeds to step S33.

In step S33, the first control unit 11 selects the human detection devices 10a and 10 that have detected the persons in the room 9a and 9c from among the human detection devices 10a, 10b, and 10c based on the detection results of the human detection devices 10a, 10b, and 10c.

In step S34, the first control unit 11 refers to the second relationship table 100A shown in fig. 13, and operates the air blowing devices 3a and 3c corresponding to the selected human detection devices 10A and 10c. Then, the process proceeds to step S35.

In step S35, the first control unit 11 determines whether or not the percentage of the number of "exceeding threshold temperature detection devices" is 50% or more. If the ratio is 50% or more, the process proceeds to step S36. On the other hand, if the ratio is less than 50%, the process proceeds to step S38.

In step S36, the first control unit 11 lowers the set temperature of the indoor unit 4 by a predetermined value. Then, the process proceeds to step S37.

In step S37, the first control unit 11 changes the state of the air conditioning system, and the flow proceeds to the blower + indoor unit operation processing flow shown in fig. 9. However, in the case of shifting to the processing flow of fig. 9, since the set temperature of the indoor unit 4 has already been lowered in step S36, the processing of step S14 may not be performed for the first time.

In step S38, the first control unit 11 changes the state of the air conditioning system, and the flow proceeds to the blower operation processing flow of fig. 7.

In step S39, the first control unit 11 changes the state of the air conditioning system and controls the air conditioning system to perform a normal operation. During the normal operation, the air conditioning system operates based on the setting information input by the user to the remote controller 1.

As described above, also in embodiment 4, as in embodiments 1 to 3, when there is the "excess threshold temperature detecting means", the blower 3 corresponding to the "excess threshold temperature detecting means" is operated. Therefore, the same effects as those of embodiments 1 to 3 are obtained.

When the ratio of the number of "exceeding threshold temperature detection devices" is 50% or more of the total, the blower device 3 is operated and the set temperature of the indoor unit 4 is lowered by a fixed value. Thus, the temperature of the indoor space can be quickly brought to the set temperature desired by the user while eliminating the temperature unevenness of the indoor space.

In embodiment 4, the human detection devices 10a, 10b, and 10C are provided in the respective regions A, B and C. The first control unit 11 saves energy because it does not operate the blower 3 when it is determined that there are no persons 9a and 9c based on the detection results of the person detection devices 10a, 10b, and 10c.

In the above description of embodiments 1 to 4, the indoor space is taken as an example of a store in a restaurant, but the present invention is not limited to this. The indoor space may be, for example, an office, a production line of a factory, a classroom, a conference room, a hall, or the like, and the air conditioning systems according to embodiments 1 to 4 described above can be used in other environments as a matter of course.

In the above description of embodiments 1 to 4, the case where the blower 3 is a propeller fan is exemplified. However, the present invention is not limited to this case, and the air blowing device 3 may be constituted by a centrifugal fan. The blower 3 may be a ceiling-mounted circulator or a floor-mounted circulator.

In embodiments 1 to 4, the wind direction of the blowing device 3 is fixed. However, the present invention is not limited to this case, and the wind direction of the air blowing device 3 may be changed. In this case, for example, the wind direction of the air blowing device 3 may be changed based on the detection results of the human detection devices 10a, 10b, and 10c. Specifically, if there are occupants 9a and 9c, air blowing devices 3a and 3c blow air toward occupants 9a and 9c. In the case where there are no persons 9a and 9C, the wind directions of the air blowing devices 3a, 3b, and 3C may be swung left and right so that the air blowing devices 3a, 3b, and 3C can blow air toward the entire regions A, B and C, respectively. Alternatively, the wind direction of the air blowing devices 3a, 3b, and 3c may be swung up and down. In this case, the vertical direction means, for example, the vertical direction, and the horizontal direction means, for example, the horizontal direction perpendicular to the vertical direction.

In embodiments 1 to 4, a plurality of levels may be further provided for the difference between the temperature detected by the temperature detection device 2 and the set temperature of the indoor unit 4. In this case, the blowing mode and the air volume of the blower 3 may be changed according to the level. The air supply mode comprises air blowing, wind shielding and the like. The wind blowing mode is a mode in which the wind direction is adjusted so that the wind is blown to the person in the room, and the wind shielding mode is a mode in which the wind direction is adjusted so that the wind is not directly blown to the person in the room.

An example in which the above-described plurality of levels are provided will be described. For example, when the level is 5, the level is 5 when the difference between the temperature detected by the temperature detection device 2 and the set temperature of the indoor unit 4 is 5 ℃. Note that, the value of the difference is set to level 4 when the temperature difference is 4 ℃, to level 3 when the temperature difference is 3 ℃, to level 2 when the temperature difference is 2 ℃, and to level 1 when the temperature difference is 1 ℃. When the difference between the detected temperature and the set temperature is level 5 or level 4, the first control unit 11 sets the blowing mode of the blower 3 to blowing and the air volume to a large value. On the other hand, when the difference between the detected temperature and the set temperature is level 2 or 1, the first control unit 11 sets the blowing mode of the blowing device 3 to the wind shield mode and sets the air volume to be small. When the difference between the detected temperature and the set temperature is level 3, the first control unit 11 sets the blowing mode of the blower 3 to blowing and sets the air volume to medium.

In addition, when only one temperature detection device 2 of the level 5 is provided and the other temperature detection devices 2 are of the level 1 or the level 2, the wind direction of the indoor unit 4 may be changed so that the wind can be blown only toward the area corresponding to the temperature detection device 2 of the level 5. Alternatively, in the case where a plurality of temperature detection devices 2 are class 5 among the temperature detection devices 2, the first control unit 11 may change the wind direction of the indoor unit 4 so that the wind can be blown only to the area where the occupant is present.

In embodiments 1 to 4, when the human detection device 10 detects a plurality of persons 9 in a single area, the first control unit 11 may oscillate the air blown from the air blowing device 3. This makes it possible to target all occupants 9 in the area for air blowing from air blowing device 3.

In embodiments 1 to 4, when human detection device 10 is an infrared sensor such as a thermopile sensor, human detection device 10 can detect the presence or absence of person in room 9 and also detect the surface temperature of person in room 9. In this case, the first control unit 11 may change the operation state of the air blowing device 3 based on the detected surface temperature. That is, the first control unit 11 adjusts the wind direction of the air blowing device 3 to be directed toward the occupant 9 having a high surface temperature. In addition, when the human detection device 10 can detect the sex, body type, and the like of the person 9 in the room, the first control unit 11 may reflect the information on the sex, body type, and the like in the control of the air blowing device 3 or the indoor unit 4. When the human detection device 10 can detect the sunshine condition in the indoor space, the first control unit 11 may reflect the information on the sunshine condition in the control of the air blowing device 3 or the indoor unit 4. The information on the sunshine status is information indicating whether or not the light is good.

The following modifications will be described: in embodiments 1 to 4 described above, when the outdoor temperature is higher than a certain temperature in summer and the human detection device 10 does not detect the person 9 in the room for a certain period of time, the human detection device 10 newly detects a modification in the case of the person 9 in the room. In this case, the first control unit 11 recognizes that the detected person 9 is a person outside the house. The first control unit 11 sets the blowing mode of the blower 3 to blow air and the air volume to be large, and blows air to the person in the room 9. Further, the air blowing is continuously performed for a certain period of time. This lowers the surface temperature of the chamber occupant 9. In this case, the first control unit 11 may perform the air blowing regardless of a difference between the temperature detected by the temperature detection device 2 and the set temperature of the indoor unit 4. Alternatively, a level dedicated for summer may be set in addition to the setting of the above-described level. In this case, even if the difference between the temperature detected by the temperature detection device 2 and the set temperature of the indoor unit 4 is small, the first control unit 11 sets the blowing mode of the blower 3 to blowing air and sets the air volume to be large, and blows air to the person 9 in the room. That is, for example, when the level is 5, the level dedicated for summer is 5 when the difference between the temperature detected by the temperature detection device 2 and the set temperature of the indoor unit 4 is 2 ℃. The value of 4 is set when the difference is 1.5 ℃, the value of 3 is set when the difference is 1 ℃, the value of 2 is set when the difference is 0.5 ℃, and the value of 1 is set when the difference is 0 ℃. In addition, this modification can also be applied to a case where the outdoor temperature is higher than a certain temperature in summer and the surface temperature of the person in the room detected by the person detection device 10 is higher than a certain value.

In embodiments 1 to 4, the case where the air conditioning system performs the cooling operation is described. However, the air conditioning systems according to embodiments 1 to 4 can also be applied to the case where the heating operation is performed. In this case, in step S2 of fig. 7, the first control unit 11 determines whether or not there is a temperature detection device whose detected temperature is lower than the first threshold value. The same applies to step S11 in fig. 9, step S22 in fig. 11, and step S31 in fig. 15. Therefore, with reference to the descriptions of embodiments 1 to 4, the "temperature detection device exceeding the threshold value" is replaced with the "temperature detection device falling below the threshold value". When the air conditioning systems according to embodiments 1 to 4 are applied to a heating operation, a heater is incorporated in the blower device 3. When air is blown from the air blowing device 3, the first control unit 11 turns on the heater to send warm air from the air blowing device 3 to the areas A, B and C. The air blowing device 3 may be constituted by a fan heater for supplying warm air. Since other configurations and operations are the same as those in the cooling, the description thereof is omitted.

Further, the following modifications will be explained: in embodiments 1 to 4 described above, in the winter, when the outdoor temperature is lower than a certain temperature and the human detection device 10 does not detect the person 9 in the room within a certain period of time, the human detection device 10 is modified to detect the person 9 in the room again. In this case, the first control unit 11 recognizes that the detected person 9 is a person outside the house. The first control unit 11 turns on the heater of the blower 3, sets the blowing mode to blowing, and sets the air volume to a large value, and blows warm air to the occupant 9. Further, the air blowing is continuously performed for a certain period of time. This increases the surface temperature of the chamber occupant 9. In this case, the first control unit 11 may perform the air blowing regardless of a difference between the temperature detected by the temperature detection device 2 and the set temperature of the indoor unit 4. Alternatively, in addition to the setting of the above-described level, a winter-dedicated level may be set. In this case, even if the difference between the temperature detected by the temperature detection device 2 and the set temperature of the indoor unit 4 is small, the first control unit 11 sets the blowing mode of the blowing device 3 to blowing air and sets the air volume to be large, and blows warm air to the person 9 in the room. That is, for example, when the level is set to 5, the level dedicated for winter is set to 5 when the difference between the temperature detected by the temperature detection device 2 and the set temperature of the indoor unit 4 is 2 ℃. Note that, the value of the difference is set to level 4 when the difference is 1.5 ℃, to level 3 when the difference is 1 ℃, to level 2 when the difference is 0.5 ℃, and to level 1 when the difference is 0 ℃. In addition, this modification can also be applied to a case where the outdoor temperature is lower than a certain temperature in winter and the surface temperature of the occupant 9 detected by the human detection device 10 is lower than a certain value.

In the case where the indoor space is a restaurant, if the first control unit 11 suddenly starts blowing air from the air blowing device 3 immediately after the person 9 sits on the tables 8a, 8b, and 8c, the person 9 in the room may feel uncomfortable or the person 9 in the room may be warned. Therefore, as shown in fig. 16, the tables 8a, 8b, and 8c may be provided with flat plates 80a, 80b, and 80c, respectively, to display messages. Fig. 16 is a side view schematically showing an example of an indoor state in which the air conditioning systems according to the modifications of embodiments 1 to 4 are installed. As an example of this message, in the case of summer, for example, "since the temperature is high, cool air is sent. And if the temperature is reduced, the operation is automatically stopped. "in the case of winter, for example," warm air is delivered because the temperature is low. And if the temperature is reduced, the operation is automatically stopped. ".

Further, when the first control unit 11 performs air blowing from the air blowing device 3, operation menus such as "hot", "cold", "blowing", "wind shielding", and "stop" may be displayed on the screens of the flat plates 80a, 80b, and 80c. In this case, the person 9 in the room can use the operation menu to finely adjust the driving method of the air blowing device 3. In this case, the first control unit 11 controls the air blowing device 3 or the indoor unit 4 based on information input to the flat panels 80a, 80b, and 80c by the room occupant 9 using the operation menu.

Instead of providing the flat plates 80a, 80b, and 80c, buttons or switches such as "hot", "cold", "blowing", "wind shielding", and "stop" may be provided on the tables 8a, 8b, and 8c. In this case, the first control unit 11 controls the air blowing device 3 or the indoor unit 4 based on information input by the person in the room 9 using the button or the switch.

The respective tables 8a, 8b, and 8c may be provided with microphones 81a, 81b, and 81c shown in fig. 16. In this case, the first control unit 11 controls the operation of the air blowing device 3 based on information of the sounds collected by the microphones 81a, 81b, and 81c by using voice recognition or the like. This operation includes switching between operation and stop of the blower 3, the wind direction, the air volume, and the like. When the first control unit 11 performs voice recognition, the first control unit 11 causes the first storage unit 14 to store a voice pattern in advance. The first control unit 11 analyzes the sounds collected by the microphones 81a, 81b, and 81c using this mode, and for example, when the microphones 81a, 81b, and 81c collect the sound emitted when the occupant 9 feels cold at room temperature, the first control unit 11 raises the set temperature of the indoor unit 4, sets the blowing mode of the blowing device 3 to the wind shield, or reduces the air volume of the blowing device 3. Examples of the sound emitted when the occupant 9 feels cold at room temperature include a sound of rubbing the body of the occupant 9, a sound of inhaling the nose, and a sound of "cold". When the microphones 81a, 81b, and 81c detect a sound generated when the occupant 9 feels heat at room temperature, the first control unit 11 lowers the set temperature of the indoor unit 4, sets the blowing mode of the blower 3 to blowing air, or increases the air volume of the blower 3. Examples of the sound emitted when the person 9 feels hot at room temperature include a sound of the person 9 drinking water in a cup, a sound of "hot", and the like. In fig. 16, both a flat board 80 and a microphone 81 are provided on each of the tables 8a, 8b, and 8c. However, this is not limitative, and either the flat plate 80 or the microphone 81 may be provided.

In addition, in the above embodiments 1 to 4, the case where the air blowing device 3 is stopped when the first time has elapsed from the start of the operation of the air blowing device 3 has been described. However, the present invention is not limited to this case, and the air blowing device 3 may be stopped based on the temperature detected by the temperature detection device 2. In this case, for example, when all the temperature detection devices 2 detect temperatures lower than the first threshold value and there is an active air blowing device 3, the second control unit 11 stops the air blowing device 3. The specific flow of processing is the processing flow from which step S5 of the processing flow of fig. 7 is deleted, and similarly the processing flow from which step S17 of the processing flow of fig. 9 is deleted.
