Description

Air conditioner management device and air conditioner management method

This disclosure relates to the management of air conditioners.

There is a convection air conditioner method as one of the air conditioner methods. In the convection air conditioning method, the air conditioner sucks air from indoors or outdoors and controls the temperature of the sucked air. Then, the air conditioner blows out the temperature-controlled air into the indoor space to adjust the temperature and humidity of the air in the indoor space.

In the case of the convection air conditioning method, if the temperature-controlled air (cold air or hot air) directly hits a person located in the indoor space, the person will have discomfort due to cold air or warm air, and comfort will be reduced. ..

On the other hand, there is a technique for setting restrictions on the lower limit value and the upper limit value for the temperature of the air blown out by the air conditioner (for example, Patent Document 1).

Japanese Patent No. 504935

In the technique of Patent Document 1, when the temperature of the blown air falls below the lower limit value during the cooling / dehumidifying operation, the cooling capacity of the air conditioner is limited regardless of whether or not a person is exposed to cold air. As a result, the air temperature and humidity of the entire indoor space rise. Further, in the technique of Patent Document 1, when the temperature of the blown air exceeds the upper limit value during the heating / humidifying operation, the heating capacity of the air conditioner is limited regardless of whether or not the person is exposed to warm air. As a result, the air temperature and humidity of the entire indoor space are reduced.

As described above, the technique of Patent Document 1 limits the air conditioning ability of the air conditioner regardless of whether or not an object (for example, a person) for air conditioning exists at the destination of the blown air from the air conditioner. .. Therefore, in the technique of Patent Document 1, since the air-conditioning object does not exist at the blow-out destination of the blown air, the air-conditioning ability is limited even when it is not necessary to limit the air-conditioning ability, and the overall comfort of the indoor space is limited. There is a problem that sex is impaired.

The main purpose of this disclosure is to solve such problems. More specifically, the main object of the present disclosure is to achieve both the comfort of an air-conditioned object existing at the destination of the blown air and the overall comfort of the indoor space.

The air conditioner management device according to the present disclosure is
A temperature determination unit that determines whether or not the temperature of the blown air, which is the temperature of the blown air from the air conditioner, exceeds the threshold value, and
An object determination unit that determines whether or not an air-conditioned object exists at the outlet of the blown air, and an object determination unit.
It has an ability control unit that limits the air conditioning ability of the air conditioner when the temperature of the blown air exceeds the threshold value and the object of the air conditioning is present at the blowing destination of the blowing air.

According to the present disclosure, it is possible to achieve both the comfort of an air-conditioned object existing at the destination of the blown air and the overall comfort of the indoor space.

FIG. 3 shows a hardware configuration example of the air conditioner management device 100 according to the present embodiment.

The air conditioner management device 100 according to the present embodiment is a computer.
The air conditioner management device 100 includes a processor 901, a main storage device 902, an auxiliary storage device 903, and a communication device 904 as hardware.
Further, as will be described later, the air conditioner management device 100 has a function configuration of a blown air temperature acquisition unit 101, a temperature limit value acquisition unit 102, a temperature determination unit 103, an object detection result acquisition unit 104, an object determination unit 105, and the like. The capacity control unit 106 is provided.

Then, the processor 901 executes these programs to operate the blown air temperature acquisition unit 101, the temperature limit value acquisition unit 102, the temperature determination unit 103, the object detection result acquisition unit 104, the object determination unit 105, and the capacity control unit 106. conduct.
In FIG. 3, the processor 901 executes a program that realizes the functions of the blown air temperature acquisition unit 101, the temperature limit value acquisition unit 102, the temperature determination unit 103, the object detection result acquisition unit 104, the object determination unit 105, and the capacity control unit 106. It schematically shows the state of being in the state.

FIG. 4 shows an example of the functional configuration of the air conditioner management device 100.

The blown air temperature acquisition unit 101 acquires the blown air temperature measured by the indoor air humidity measuring device 51 from the indoor air humidity measuring device 51. Then, the blown air temperature acquisition unit 101 notifies the temperature determination unit 103 of the acquired blown air temperature.

The temperature limit value acquisition unit 102 acquires the blown air temperature limit value. The blown air temperature limit value is a limit value of the blown air temperature and is a threshold value. When the outside air processing unit 20 is performing the cooling / dehumidifying operation, the blown air temperature limit value is the lower limit value of the blown air temperature. Hereinafter, the lower limit of the blown air temperature is referred to as a lower temperature lower limit. When the outside air processing unit 20 is performing the heating / humidifying operation, the blown air temperature limit value is the upper limit value of the blown air temperature. Hereinafter, the upper limit value of the blown air temperature is referred to as a temperature upper limit value.
The temperature limit value acquisition unit 102 notifies the temperature determination unit 103 of the acquired blown air temperature limit value.

The temperature determination unit 103 determines whether or not the blown air temperature exceeds the blown air temperature limit value. That is, when the outside air processing unit 20 is performing the cooling / dehumidifying operation, the temperature determination unit 103 determines whether or not the temperature of the blown air is below the lower limit of the temperature. On the other hand, when the outside air processing unit 20 is performing the heating / humidifying operation, the temperature determination unit 103 determines whether or not the temperature of the blown air exceeds the upper limit of the temperature.
Then, the temperature determination unit 103 notifies the object determination unit 105 and the ability control unit 106 of the determination result.

The object detection result acquisition unit 104 acquires the detection result of the position of the person from the person position detection device 60 as the object detection result. In the present embodiment, since the air-conditioned object is a person, the temperature determination unit 103 acquires the detection result of the position of the person from the person position detection device 60 as the object detection result. When the object of air conditioning is an animal, the temperature determination unit 103 acquires the detection result of the position of the animal from the human position detection device 60 or another sensor. In the following, an example in which the object of air conditioning is a person will be described.
The object detection result acquisition unit 104 notifies the object determination unit 105 of the object detection result.

The object determination unit 105 determines whether or not there is a person at the destination of the blown air based on the object detection result notified from the object detection result acquisition unit 104.
It is assumed that the object determination unit 105 stores the blowout destination area (hereinafter, referred to as the blowout destination area) for each outside air processing unit 20. The object determination unit 105 determines that there is a person at the outlet of the blown air when the position of the person shown in the object detection result matches the blowout area.
The object determination unit 105 notifies the ability control unit 106 of the determination result.

When the temperature determination unit 103 determines that the blown air temperature exceeds the blown air temperature limit value, and the object determination unit 105 determines that there is a person at the blown air destination, the capacity control unit 106 determines that the air is blown out. Limit the air conditioning capacity of the harmonizer. Specifically, the capacity control unit 106 outputs a control signal for limiting the air conditioning capacity to the outside air processing unit 20.

When the air conditioner is performing cooling and dehumidifying operation, if the temperature of the blown air is lower than the lower limit of the temperature and there is a person at the destination of the blown air, the blown air (cold air) that is colder than the lower limit of the temperature hits the person. .. In this case, the person is likely to be uncomfortable with the cold air. Therefore, the capacity control unit 106 limits the cooling / dehumidifying capacity of the air conditioner so that the temperature of the blown air does not exceed the lower limit of the temperature, and reduces the discomfort caused by the cold air.
In addition, when the air conditioner is performing heating and humidification operation, the temperature of the blown air is higher than the upper limit of the temperature, and if there is a person at the destination of the blown air, the blown air (warm air) warmer than the upper limit of the temperature is used. Is a person. In this case, the person is likely to be uncomfortable with the warm air. Therefore, the capacity control unit 106 limits the heating / humidifying capacity of the air conditioner so that the temperature of the blown air does not exceed the upper limit of the temperature, and reduces the discomfort caused by the warm air.

If the object determination unit 105 determines that there is no person at the outlet of the blown air, the capacity control unit 106 does not limit the air conditioning capacity of the air conditioner. At this time, if the air conditioning capacity of the air conditioner is already limited, the capacity control unit 106 releases the restriction on the air conditioning capacity of the air conditioner. If the temperature determination unit 103 determines that the blown air temperature does not exceed the blown air temperature limit value and the air conditioning capacity of the air conditioner is already limited, the capacity control unit 106 will perform air. Remove the restriction on the air conditioning capacity of the air conditioner.

FIG. 5 shows a configuration example of the refrigerant circuit according to the present embodiment.
As shown in FIG. 5, the outdoor unit 10 includes a compressor 11, a four-way valve 12, an outdoor heat exchanger 13, and an outdoor unit fan 14. Further, the outside air processing unit 20 has an expansion valve 21 and an outside air processing heat exchanger 22.

A refrigerant circuit is configured by connecting the compressor 11, the four-way valve 12, the outdoor heat exchanger 13, the expansion valve 21, and the outside air processing heat exchanger 22 in an annular shape by the refrigerant pipe 30.

The compressor 11 compresses the low-temperature and low-pressure refrigerants and converts them into high-temperature and high-pressure refrigerants. The compressor 11 is driven by, for example, an inverter, and the capacity (the amount of refrigerant discharged per unit time) is controlled.
The four-way valve 12 switches the flow of the refrigerant according to the operation mode of the air conditioner, for example, the cooling / dehumidifying operation or the heating / humidifying operation.
The outdoor heat exchanger 13 exchanges heat between the refrigerant flowing through the refrigerant circuit and the outdoor air.
An outdoor unit fan 14 is adjacent to the outdoor heat exchanger 13. The outdoor unit fan 14 blows air to the outdoor heat exchanger 13. The amount of air blown can be adjusted by controlling the rotation speed of the outdoor unit fan 14.
The expansion valve 21 is composed of a valve whose opening degree can be variably controlled, for example, an electronic expansion valve. By controlling the opening degree of the expansion valve 21, the amount of decompression of the refrigerant is controlled.
The outside air processing heat exchanger 22 exchanges heat between the refrigerant flowing through the refrigerant circuit and the air taken in from the outside.
By controlling the rotation speed of the fan of the air supply air blowing means 24 shown in FIG. 6, the amount of air blown to the outside air processing heat exchanger 22 can be adjusted.

FIG. 6 shows a configuration example of the outside air processing unit 20.
The outside air processing unit 20 includes an outside air processing heat exchanger 22, a total heat exchanger 23, an air supply air blowing means 24 for supplying outdoor air to the indoor space, and an exhaust air blowing means for discharging indoor air to the outside. 25, a humidifying device 26, a blown air temperature measuring device 50, and an indoor air humidity measuring device 51 are mounted.

During the cooling / dehumidifying operation, the outside air taken into the outside air processing unit 20 is heat-exchanged with the indoor air taken in by the total heat exchanger 23. Then, the air after heat exchange is temperature-controlled by the outside air processing heat exchanger 22 and then blown out into the indoor space (solid arrow). During the heating / humidifying operation, the air is humidified by the humidifying device 26 and blown out into the indoor space. The taken-in indoor air is heat-exchanged with the outside air by the total heat exchanger 23, and the air after the heat exchange is blown out to the outdoor space (broken arrow).

*** Explanation of operation ***
Hereinafter, an operation example of the air conditioner management device 100 according to the present embodiment will be described.

As a premise, it is assumed that the outlet area is set for each outside air processing unit 20 shown in FIG. For example, as shown by the broken line in FIG. 7, the indoor space may be evenly divided according to the number and position of the air outlets 41, and the air outlet area may be set.
Alternatively, the range hit by the blown air from the outlet 41 is measured in advance using a wind speed sensor or the like, or is estimated by simulation or the like, and the range obtained by the measurement or estimation is the blowout destination area. May be set to. In this case, as the outlet area, for example, the range shown by the rectangle of FIG. 8 can be obtained.
The outlet area is also simply referred to as an area.

The object determination unit 105 shall hold, for example, the outlet area management table shown in FIG.
The object determination unit 105 manages the position coordinates of the blowout destination area for each outside air processing unit 20 in the blowout destination area management table of FIG. In the outlet area management table of FIG. 11, the X and Y coordinates of the four points of the outlet area (rectangle) are shown.

Further, it is assumed that the lower limit of the temperature is set in advance in each outside air processing unit 20 or each outlet 41.
The same lower temperature lower limit value may be uniformly set for all the outside air processing units 20, or different temperature lower limit values may be set for each outside air processing unit 20. Further, the lower limit of the temperature can be changed by the user of the air conditioner management device 100. For example, the user of the air conditioner management device 100 can change the temperature lower limit value during the operation of the air conditioner management device 100.

Similarly, it is assumed that the upper limit of the temperature is set in advance in each outside air processing unit 20 or each outlet 41.
The same temperature upper limit value may be uniformly set for all the outside air processing units 20, or different temperature upper limit values may be set for each outside air processing unit 20. Further, the upper limit of the temperature can be changed by the user of the air conditioner management device 100. For example, the user of the air conditioner management device 100 can change the temperature upper limit value during the operation of the air conditioner management device 100.

When the temperature lower limit value and the temperature upper limit value are different for each outside air processing unit 20, the temperature limit value acquisition unit 102 acquires the temperature lower limit value or the temperature upper limit value from each outside air processing unit 20.
The temperature determination unit 103 manages the temperature lower limit value or the temperature upper limit value for each outside air processing unit 20 acquired by the temperature limit value acquisition unit 102, for example, in the temperature control table shown in FIG.
In the temperature control table of FIG. 12, the lower limit of temperature is managed for each outside air processing unit 20. When the heating / humidifying operation is performed, a temperature control table in which the upper limit of the temperature is described is used.

Further, the capacity control unit 106 shall hold, for example, the air conditioning capacity management table shown in FIG.
Based on the air conditioning capacity management table of FIG. 13, the capacity control unit 106 manages whether or not there is a limit on the air conditioning capacity for each outside air processing unit 20.

On the premise of the above, an operation example of the air conditioner management device 100 according to the present embodiment will be described with reference to FIGS. 9 and 10.
FIG. 9 shows an operation example of the air conditioner management device 100 when the air conditioner performs the cooling / dehumidifying operation.
FIG. 10 shows an operation example of the air conditioner management device 100 when the air conditioner performs a heating / humidifying operation.

First, an operation example of the air conditioner management device 100 when the air conditioner performs the cooling / dehumidifying operation will be described with reference to FIG.
Note that FIG. 9 shows an operation example of the air conditioner management device 100 for one set of the outside air processing unit 20 and the air outlet 41. As shown in FIG. 2, when there are a plurality of pairs of the outside air treatment unit 20 and the air outlet 41, the air conditioner management device 100 performs the flow shown in FIG. 9 for each pair of the outside air treatment unit 20 and the air outlet 41. To carry out.

First, in step S901, the temperature limit value acquisition unit 102 acquires the temperature lower limit value from the outside air processing unit 20. The temperature limit value acquisition unit 102 notifies the temperature determination unit 103 of the acquired temperature lower limit value. The temperature determination unit 103 sets the notified lower limit of the temperature in the temperature control table of FIG.

Next, in step S902, the blown air temperature acquisition unit 101 acquires the blown air temperature of the outside air processing unit 20 from the blown air temperature measuring device 50. The blown air temperature acquisition unit 101 notifies the temperature determination unit 103 of the acquired blown air temperature.

Next, in step S903, the temperature determination unit 103 determines whether or not the temperature of the blown air is below the lower limit of the temperature. More specifically, the temperature determination unit 103 compares the temperature of the blown air notified from the blown air temperature acquisition unit 101 with the lower limit of the temperature of the corresponding outside air processing unit 20 in the temperature control table of FIG.
Then, the temperature determination unit 103 notifies the object determination unit 105 and the ability control unit 106 of the determination result.

When the temperature determination unit 103 determines that the temperature of the blown air is below the lower limit of the temperature (YES in step S903), in step S904, the object determination unit 105 puts a person in the blow destination area of the outside air processing unit 20. Determine if there is any.
Specifically, in the object determination unit 105, the location of the person shown in the object detection result acquired by the object detection result acquisition unit 104 is the corresponding outside air processing unit 20 in the blowout area management table of FIG. Determine whether or not it is included in the coordinate range of the blowout area. It is assumed that the object detection result acquisition unit 104 periodically acquires the object detection result from the human position detection device 60 independently of the flow of FIG. 9, and notifies the object determination unit 105 of the object detection result.
The object determination unit 105 notifies the ability control unit 106 of the determination result.

On the other hand, when the temperature determination unit 103 determines that the temperature of the blown air is not lower than the lower limit of the temperature (NO in step S903), the process proceeds to step S906.

When the object determination unit 105 determines that there is a person in the blow-out area of the outside air processing unit 20 (YES in step S904), in step S905, the capacity control unit 106 causes the blow-out air temperature to be equal to or higher than the lower temperature limit value. The air conditioning capacity of the outside air processing unit 20 is limited. For example, the capacity control unit 106 limits the air conditioning capacity of the outside air processing unit 20 by adjusting the opening degree of the expansion valve, adjusting the compressor frequency, adjusting the air volume of the fan, and the like. More specifically, the capacity control unit 106 limits the air conditioning capacity by lowering the opening degree of the expansion valve, lowering the frequency of the compressor, increasing the air volume of the fan, or a combination thereof. The capacity control unit 106 outputs a control signal for the opening degree of the expansion valve, a control signal for the compressor frequency, and a control signal for the air volume of the fan to the outside air processing unit 20.
The method of limiting the air conditioning capacity by the capacity control unit 106 is not limited to these methods.

On the other hand, when the object determination unit 105 determines that there is no person in the outlet area of the outside air processing unit 20 (NO in step S904), or the temperature determination unit 103 determines that the temperature of the blown air is not lower than the lower limit of the temperature. If so (NO in step S903), in step S906, the capacity control unit 106 determines whether or not the air conditioning capacity of the outside air processing unit 20 has already been limited. Specifically, the capacity control unit 106 determines whether or not the air conditioning capacity of the outside air processing unit 20 has already been limited by referring to the air conditioning capacity management table of FIG.
If the air conditioning capacity of the outside air processing unit 20 has already been limited (YES in step S906), the capacity control unit 106 releases the restriction on the air conditioning capacity of the outside air processing unit 20 in step S907. For example, the capacity control unit 106 returns the air conditioning capacity of the outside air processing unit 20 to the level before the limit by readjusting the opening degree of the expansion valve, readjusting the compressor frequency, readjusting the air volume of the fan, and the like. The capacity control unit 106 outputs a control signal for the opening degree of the expansion valve, a control signal for the compressor frequency, and a control signal for the air volume of the fan to the outside air processing unit 20.

If the air conditioning capacity of the outside air processing unit 20 is not limited (NO in step S906), the processing returns to step S902.

When the operation of the outside air processing unit 20 is completed (YES in step S908), the air conditioner management device 100 ends the processing of the outside air processing unit 20.
On the other hand, when the operation of the outside air processing unit 20 continues (NO in step S908), the processing returns to step S902.

The operation of the air conditioner management device 100 during the heating / humidifying operation shown in FIG. 10 is basically the same as the operation of FIG.
The operation of FIG. 10 and the operation of FIG. 9 are the same except that the temperature upper limit value is acquired in step S1001 and the blown air temperature and the temperature upper limit value are compared in step S1003. That is, steps S1002 and S1004 to S1008 are the same as steps S902 and S904 to S908 of FIG.

*** Explanation of the effect of the embodiment ***
In the present embodiment, when the temperature of the blown air exceeds the temperature limit value of the blown air and an air-conditioning object exists at the blow-out destination of the blown air, the air-conditioning ability of the air conditioner is limited. Therefore, when there is a person at the destination of the cold air or the hot air, it is possible to avoid the discomfort caused by the cold air or the hot air hitting the person. Further, when there is no person at the destination of the cold air or the hot air, the air conditioning ability is maintained, so that the comfort of the entire indoor space can be maintained. As described above, according to the present embodiment, it is possible to achieve both the comfort of the person at the destination of the blown air and the overall comfort of the indoor space.

Embodiment 2.
In this embodiment, the difference from the first embodiment will be mainly described.
The matters not explained below are the same as those in the first embodiment.

In the present embodiment, the capacity control unit 106 is an air conditioner that limits the air conditioner capacity when the air conditioner capacity of any one of the plurality of air conditioners is limited. Increase the air conditioning capacity of air conditioners other than certain restricted air conditioners. That is, in the present embodiment, the capacity control unit 106 increases the air conditioning capacity of the air conditioner other than the limiting air conditioner to complement the limited air conditioning capacity of the limiting air conditioner.

For example, when the temperature of the blown air from the blowout port 41A shown in FIG. 8 is below the lower limit of the temperature and there is a person in the blowout destination area A, the capacity control unit 106 limits the air conditioning capacity of the outside air processing unit 20A. .. In this case, the outside air processing unit 20A corresponds to the limiting air conditioner. Due to the limitation of the air conditioning capacity of the outside air processing unit 20A, the temperature of the outlet area A and its surroundings rises. In order to suppress this temperature rise, the capacity control unit 106 increases the air conditioning capacity of the outside air processing unit 20 near the outside air processing unit 20A if there is no person in the blowing destination area near the blowing destination area A. For example, suppose that there are no people in the outlet areas B, D, and E, which are the outlet areas in the vicinity of the outlet area A. In this case, the capacity control unit 106 increases the air conditioning capacity of the outside air processing units 20B, D, and E. As a result, the temperature of the outlet area A and its surroundings can be set to the same level as the temperature of other parts of the indoor space.
For example, the capacity control unit 106 acquires the temperatures of the blowout destination areas A, B, D, and E. Then, the capacity control unit 106 increases the air conditioning capacity of the outside air processing units 20B, D, and E so that the temperature of the outlet area A becomes the same as the temperature of the outlet areas B, D, and E.
Further, the capacity control unit 106 may increase the air conditioning capacity of the outside air processing units 20B, D and E in order to adjust the humidity in and around the blowout area A. That is, the capacity control unit 106 acquires the humidity of the blowout destination areas A, B, D, and E. Then, the capacity control unit 106 increases the air conditioning capacity of the outside air processing units 20B, D, and E so that the humidity of the outlet area A becomes the same as the humidity of the outlet areas B, D, and E.

Hereinafter, an example in which the air conditioner management device 100 processes the outside air processing unit 20B will be described.

In FIG. 14, steps S901 to S908 are the same as those shown in FIG. 9, and thus the description thereof will be omitted.
If the air conditioning capacity of the outside air processing unit 20B is not limited in step S906, is the capacity control unit 106 limited in the air conditioning capacity of the outside air processing unit 20 in the vicinity of the outside air processing unit 20B in step S909? Judge whether or not. Specifically, the capacity control unit 106 determines whether or not the air conditioning capacity of the outside air processing unit 20 in the vicinity of the outside air processing unit 20B is limited by referring to the air conditioning capacity management table of FIG. In the example of FIG. 13, the air conditioning capacity of the outside air processing unit 20A in the vicinity of the outside air processing unit 20B is limited.
Therefore, the capacity control unit 106 increases the air conditioning capacity of the outside air processing unit 20B in step S910.
For example, the capacity control unit 106 increases the air conditioning capacity of the outside air processing unit 20B by increasing the opening degree of the expansion valve, increasing the frequency of the compressor, decreasing the air volume of the fan, or a combination thereof.

By performing the same processing on the outside air processing unit 20D and the outside air processing unit 20E by the capacity control unit 106, the temperature and humidity of the outlet area A are improved by increasing the air conditioning capacity of the outside air processing units 20B, D and E. can do.

Therefore, according to the present embodiment, even when the air conditioning capacity of the air conditioner is limited, the temperature and humidity of the blowout area can be kept comfortable by enhancing the air conditioning capacity of the other air conditioners. can.

Embodiment 3.
In this embodiment, the difference from the first embodiment will be mainly described.
The matters not explained below are the same as those in the first embodiment.

In the present embodiment, the air outlet 41 is provided with a mechanism capable of adjusting the wind direction. Further, in the present embodiment, the outside air processing unit 20 can change the blowing direction of the blown air in response to an instruction from the air conditioner management device 100. Other configurations are the same as those in the first embodiment.

In the present embodiment, as shown in FIGS. 15 and 16, the outlet 41A is provided with three outlet directions, and therefore the outlet 41A has three outlet areas. Specifically, the outlet 41A has a outlet area 501, an outlet area 502, and an outlet area 503. Note that FIG. 15 shows a state in which the outlet 41A and the outlet areas 501 to 503 are viewed from the horizontal direction. FIG. 16 shows a state in which the outlet 41A and the outlet areas 501 to 503 are viewed from the vertical direction.
In addition, the range in which the blown air from the blowout port 41A hits by switching the blowout direction is measured in advance using a wind speed sensor or the like, or estimated by simulation or the like, and obtained by measurement or estimation. The range may be set to the outlet area 501 to 503.
15 and 16 show an example of the outlet area of the outlet 41A, but other outlets 41 have the same outlet area configuration.

15 and 16 show an example of a blowout destination area obtained when the blowout direction is switched up and down. Instead of this, the blow-out destination area obtained when the blow-out direction is switched to the left-right direction may be used. Further, in the examples of FIGS. 15 and 16, three outlet areas corresponding to the three outlet directions are shown, but more outlet areas may be provided by providing more outlet directions. Further, in FIGS. 15 and 16, there is no overlap between the outlet areas 501 to 503, but there may be overlap between the outlet areas.

FIG. 17 shows an operation example of the air conditioner management device 100 according to the present embodiment during the cooling / dehumidifying operation. Hereinafter, an example in which the air conditioner management device 100 processes the outside air processing unit 20A and the air outlet 41A will be described.

In FIG. 17, since steps S901 to S903 are the same as those shown in FIG. 9, the description thereof will be omitted.

In the present embodiment, in step S904, the object determination unit 105 determines whether or not there is a person in any of the outlet areas 501 to 503 of the outlet 41A.
In the present embodiment, it is assumed that the object determination unit 105 holds the outlet area management table shown in FIG. In the object determination unit 105, the location of the person shown in the object detection result acquired by the object detection result acquisition unit 104 is the coordinates of any of the outlet areas 501 to 503 shown in the outlet area management table of FIG. Determine if it is included in the range. Further, when the object determination unit 105 determines that a person exists in any of the outlet areas 501 to 503 of the outlet 41A, in step S911, the outlet area where no person exists (hereinafter referred to as an unmanned area) is determined. Determine if it exists. If there is an unmanned area, the object determination unit 105 notifies the ability control unit 106 of the unmanned area. For example, if there are people in the outlet area 501 and the outlet area 502, but there are no people in the outlet area 503, the object determination unit 105 has people in the outlet area 501 and the outlet area 502. However, the ability control unit 106 is notified that there are no people in the blowout area 503.

If there is no unmanned area in step S911, the process proceeds to step S905. That is, in the present embodiment, the capacity control unit 106 changes the blowing direction of the blowing air to a direction in which the blowing air temperature is below the lower limit of the temperature, there is a person in one of the blowing destination areas, and there is no person. If this is not possible, the air conditioning capacity of the outside air processing unit 20A is limited.
Since the process itself of step S905 is the same as that shown in FIG. 9, the description thereof will be omitted.
Further, since the processing after step S906 is the same as that shown in FIG. 9, the description thereof will be omitted.

On the other hand, if there is an unmanned area in step S911, the ability control unit 106 determines in step S912 to change the blowing direction to the direction of the unmanned area. That is, in the capacity control unit 106, when the temperature of the blown air is below the lower limit of the temperature and there is a person in any of the blowout destination areas, but the blowing direction of the blown air can be changed to a direction in which there is no person. , The blowing direction of the blown air is changed to a direction in which no one is present without limiting the air conditioning capacity of the outside air processing unit 20A.
In the above example, since the blowout destination area 503 is an unmanned area, the capacity control unit 106 decides to switch the blowout destination of the blown air from the blowout port 41A to the blowout destination area 503. Then, the capacity control unit 106 outputs a control signal for switching the blowout destination to the blowout destination area 503 to the outside air processing unit 20A.
If the outlet of the outlet 41A is already in the outlet area 503, the capacity control unit 106 does not output the control signal.
After that, the processes after step S906 are performed.

The operation of the air conditioner management device 100 during heating and humidification can be realized by adding step S911 and step S912 to FIG.

As described above, in the present embodiment, when it is possible to avoid hitting a person with cold air or hot air by switching the blowing direction of the blowing air, only the blowing direction is switched and the air conditioning ability is not limited. Therefore, according to the present embodiment, the opportunity to limit the air conditioning ability can be reduced, and the temperature and humidity of the indoor space can be kept comfortable.
