FIG. 3 is a diagram showing an example of facility information 38A recorded in the facility information/air conditioning control information DB 38. As shown in FIG.

As shown in FIG. 3, information for each air conditioning area 6 (rooms 1, 2, . . . ) is recorded in the facility information 38A.

For example, for one air-conditioned area 6 (room), the facility information 38A includes objects existing in the air-conditioned area 6 included in the facility information input by the information input processing unit 30C, such as furniture such as cabinets and partitions. Information (number, position, height, direction, etc.), information about the equipment provided in the air conditioning area 6, and the like are recorded.

In addition, the facility information 38A includes air conditioner information on the air conditioners 10 provided in the air conditioning area 6 (such as the position and operating state of the outlet for each air conditioner 10), and vent information on the vent 7 (for each vent 7). position, open/closed state, etc.), exhaust port information on the structure 8 (exhaust port) that can be exhausted (position of each exhaust port, open/closed state, etc.), door/window information on doors/windows (position of each door/window, open/closed state, etc.) open/closed state, etc.), and if an air purifier with an air purifying function is installed in the air-conditioned area 6, air purifier information regarding the air purifier (position of the suction port, operating state, etc.).

The operating state, opening/closing state, and the like recorded in the facility information 38A are detected by image processing performed by the image processing unit 30B on the image captured by the imaging device 11, and are also collected from the air conditioning control device 3 or the facility exhaust control device 5. It will be updated as appropriate based on the information available.

FIG. 4 is a diagram showing an example of air conditioning control information 38B recorded in the facility information/air conditioning control information DB 38. As shown in FIG.

As shown in FIG. 4, information for each air conditioning area 6 (rooms 1, 2, . . . ) is recorded in the air conditioning control information 38B.

For example, the air-conditioning control information 38B includes visitor information (number of people, position, direction, etc.) and facility information regarding the guests staying in the room as the next story necessary for air-conditioning management for one air-conditioning area 6 (room). Obstacle information (number, position, height, orientation, etc.) is recorded for obstacles such as portable partitions, presentation screens and displays, chairs, tables, etc. that are not provided and arbitrarily brought into the room.

The visitor information and obstacle information recorded in the air-conditioning control information 38B are detected, for example, by image processing performed by the image processing unit 30B on images captured by the imaging device 11, and are updated as appropriate.

Further, ventilation control information for controlling ventilation in the air-conditioned area 6 is recorded in the air-conditioning control information 38B based on the facility information 38A and the resident information and obstacle information in the air-conditioning control information 38B.

The ventilation control information includes, for example, an interval (ventilation interval time) at which a ventilation operation is performed instead of the normal air conditioning control that is performed when there is a resident in the air conditioning area 6 (indoor), and the air conditioning area 6 installed. Control information for performing ventilation operations (wind direction, air volume (intensity), ventilation operation time, etc.) is included for each air conditioner 10 .

Next, the operation of the air conditioning control system according to this embodiment will be described.

FIG. 5 is a flowchart showing the operation for ventilation control of the air conditioning management device 200 in this embodiment. When there is a resident in the air-conditioned area 6, the air-conditioning management device 200 performs a ventilation operation for ventilation in the air-conditioned area 6 at predetermined time intervals while the normal air-conditioning operation is performed by the air conditioner 10. It is executed by the air conditioner 10 based on the existing obstacles, the state of the vent 7, and the structure 8 capable of exhausting air (first ventilation control). In addition, when the resident leaves the air-conditioned area 6, the air-conditioning management device 200 causes the air conditioner 10 to perform a ventilation operation in which the ventilation of the air-conditioned area 6 is completed in a short time, which is different from the first ventilation control (second ventilation control). 2 ventilation control)
FIG. 6 is a diagram showing an example of the layout of air conditioners 10, vents 7, and structures 8 (including windows and doors) capable of exhausting air in an air-conditioned area 6 (indoor). The air conditioning area 6 shown in FIG. 6 is provided with a plurality of doors 41A and 41B serving as exhaust ports for ventilation, exhaust ports 42A and 42B, and windows 43A and 44A. In addition, cabinets 45 and partitions 46 are installed in the air-conditioned area 6 as obstacles that affect the airflow of the air-conditioned area. It also shows that there are a plurality of visitors 50A, 50B, and 50C. Also, in the air conditioning area 6, for example, three air conditioners 60A, 60B, and 60C are installed.

When performing ventilation efficiently, it is desirable to send the airflow for ventilation sent out from the outlet of the air conditioners 60A, 60B, 60C in a substantially straight line toward the outlet. For example, when the door 41A is open, the airflow WB is sent out from the outlet of the air conditioner 60B toward the door 41A.

On the other hand, for example, when the window 43A is in an open state, when a substantially linear airflow is sent out from the outlet of the air conditioner 60A toward the window 43A, the cabinet 45 shields the airflow. inadequate ventilation. In such a case, the direction, strength, or delivery time of the air flow WA delivered from the outlet of the air conditioner 60A depends on the installation position, height, direction, etc. of the cabinet 45 and the status of other outlets. Control. This avoids obstruction of the air flow by the cabinet 45 and enables efficient ventilation.

When the processing based on the air conditioning management program is started, the cooperative control device 30 of the air conditioning management device 200 executes initial setting processing for air conditioning management (step S1). In the initial setting process, for example, facility information relating to the air conditioning area 6 (target area such as a conference room) to be managed is input and recorded in the facility information/air conditioning control information DB 38 . The information input processing unit 30C receives, for example, facility information input by an operator through an input operation on the operation unit 35, facility information based on facility drawing information collected from the management system 42, or facility information captured by the imaging device 11. Facility information and the like regarding structures detected by the image processing unit 30B based on the obtained image is input and recorded in the facility information/air conditioning control information DB 38 .

On the other hand, the image processing section 30B performs image processing for detecting a visitor on the image captured by the imaging device 11 collected through the imaging control device 4 and the imaging device communication section 32 .

When the image processing unit 30B cannot detect the visitor from the image captured by the imaging device 11 (step S11, NO), the imaging device 11 similarly captures an image after ΔT time has elapsed (step S10). Image processing is performed to detect visitors from the captured image.

When the image processing unit 30B detects a sojourner, the control shifts to the first ventilation control when there is a sojourner.

The cooperative control device 30 determines whether or not a predetermined time for performing the ventilation operation has passed. That is, when there is a resident, the air conditioner 10 performs a normal air conditioning operation. In a normal air conditioning operation, the air conditioner 10 sends out conditioned air according to the set temperature (cooling, heating)/air volume set for the air conditioner 10 . When a predetermined time has passed in this state, the air conditioner 10 is caused to perform an operation for ventilation.

After a predetermined time (ventilation interval time) has passed (step S12, YES), the air-conditioning control information setting unit 30E collects various kinds of information to generate air-conditioning control information for the first ventilation control. That is, the air-conditioning control information setting unit 30E collects visitor information including the position of the visitor detected by image processing by the image processing unit 30B and obstacle information including the size/position of the obstacle (step S13). . In addition, the air conditioning control information setting unit 30E collects information on objects (such as fixtures) existing in the air conditioning area 6 indicated by the facility information.

Further, the air conditioning control information setting unit 30E collects air conditioner information indicated by the facility information, vent information regarding the vent 7, and exhaust vent information regarding the structure 8 (exhaust vent) capable of exhausting air (step S14).

If the resident information, obstacle information, and facility information are set in advance, they do not have to be collected at this point.

Based on the collected information, the air-conditioning control information setting unit 30E adjusts the air-conditioning control information from the outlet of the air conditioner 10 to the air outlet formed in a substantially straight line in the direction of the air outlet 7 or the structure 8 that can exhaust air. If the object detected by the image processing unit 30B becomes an obstacle to the airflow, control at least one of the direction, intensity, and delivery time of the airflow from the outlet according to the position of the object. Generate ventilation control information for

An example of generating ventilation control information will be described below.

In the present embodiment, it is determined whether or not the object detected by the image processing unit 30B obstructs ventilation with respect to the air flow from the outlet by calculating the shielding rate.

7 and 8 are diagrams for explaining an example of simple calculation of the shielding rate. FIG. 7 is an example of shielding in the height direction when it is assumed that the airflow for ventilation is sent out from the air conditioner 60C shown in FIG. 6 and exhausted from the window 44A provided on the front side of the air conditioner 60C. indicates FIG. 8 shows an example of shielding in the width direction when it is assumed that the airflow for ventilation is sent out from the air conditioner 60A shown in FIG. 6 and exhausted from the window 43A provided on the front side of the air conditioner 60A. show.

In FIG. 7, the height from the floor surface of the outlet center point P of the air conditioner 60C: Hairc. [m], the height from the floor of the center point Q of the window 44A serving as the discharge port: Hexit. [m], the height of the zenith point O of the partition 46 (obstacle) from the floor: Hobst. [m], and the length of point C and point O where the line segment PQ intersects the obstacle: h [m].

As shown in FIG. 7, a line segment connecting point P and point Q and height Hobst. By geometrically calculating whether or not the obstacle (partition 46) intersects with the obstacle (partition 46), it is possible to determine the range in which the obstacle (partition 46) is an obstacle in the height direction.

In FIG. 8, the apparent width of the outlet of the air conditioner 60A in the horizontal plane direction: Wairc. [m], horizontal apparent width of the window 43A used as the discharge port: Hexit. [m], the apparent width of the cabinet 45 (obstacle) blocking the air flow (W2) from the outlet: w [m], the width of the air flow (W1) passing through without being blocked by the cabinet 45 (obstacle) Apparent width: Wpass [m].

As shown in FIG. 8, it is determined to what extent the obstacle (cabinet 45) is an obstacle in the width direction with respect to the range connecting the outlet of the air conditioner 60A and the outlet (window 43A). can do.

Based on the position of the outlet of the air conditioner 10, the position of the outlet used for exhausting air, and the position of obstacles, the air conditioning control information setting unit 30E controls the height direction and the width direction as shown in FIGS. The shielding rate η is calculated according to the condition of the obstacle.

Shielding rate η
= (passage area when shielded by a shield) / (passage area when there is no shield) * 100
= (w*h)/(w+Wpass)*1*100 [%]
7 and 8 show examples of different air conditioners 60A and 60C, exhaust ports (window 44A and window 43A), and obstacles (partition 46 and cabinet 45) in the description of the height direction and width direction. However, in calculating the shielding rate η, common information about air conditioners, air outlets, and obstacles is used for the height direction and the width direction.

As a result of calculating the shielding rate η, the air conditioning control information setting unit 30E determines that when the shielding rate η is lower than a preset reference value, that is, for an air flow formed in a substantially straight line from the outlet to the exhaust port, If the obstructions do not greatly affect ventilation and sufficient ventilation is possible, the air outlet should be arranged so that the air flow is approximately straight from the outlet to the exhaust port for efficient ventilation. Determine the direction of airflow from

On the other hand, when the shielding rate η is equal to or higher than the preset reference value, the air conditioning control information setting unit 30E directs the air flow from the outlet in the direction to avoid the obstacle so that the shielding rate η is lower than the reference value. Determine direction.

As a result, according to the position of obstacles such as cabinets, partitions, curtains, etc., it is possible to create airflow in the appropriate direction from the air outlet to the structure (exhaust outlet) that can be exhausted, and to perform quick and efficient ventilation. make it

When determining the direction of the air flow from the outlet, it may be determined based on not only the position of the obstacle but also the position of the resident. For example, the direction is determined so that the air flow from the outlet passes around the resident. That is, by causing the air flow for ventilation to flow around the resident, it is possible to efficiently ventilate the air around the resident, including the exhalation of the resident.

In addition, when ventilating airflow around the resident, increasing the airflow may cause discomfort to the resident, so the airflow shall be determined at a predetermined standard or less. . In addition, in order to prioritize ventilation efficiency, the direction of the air flow is determined to avoid not only obstacles but also the occupants instead of flowing air for ventilation around the occupants, exceeding the standard. You may make it determine by an air volume.

Further, in the above description, the direction of the air flow from the outlet is determined for the outlet that can deliver a substantially linear air flow from the outlet to the outlet. Determine the direction of the air flow from the outlet by selecting the vent 7 and the structure 8 that can be used as an exhaust outlet, or the exhaust outlet that can be efficiently ventilated by targeting the window or door. .

That is, effective ventilation can be performed according to the current state of the exhaust port ascertained based on the image captured by the imaging device 11 .

In addition, if it is not possible to send out a substantially straight air flow from the outlet to the exhaust port, increase the strength (air volume) when sending out the air flow, or lengthen the time for sending out the air flow. , to allow for efficient ventilation.

In addition, it is also possible to determine the intensity of the air flow from the outlet or the delivery time according to the number of visitors indicated by the visitor information. For example, the greater the number of occupants, the greater the need for ventilation, increasing the intensity of the airflow or increasing the delivery time.

It should be noted that the above-described method for determining the direction, intensity, or delivery time of the airflow to be delivered from the outlet is an example, and other determination methods can be used.

As described above, the air-conditioning control information setting unit 30E determines the direction, strength, or delivery time of the airflow based on the facility information, the resident information, and the obstacle information indicating the current state of the air-conditioned area 6 ( Step S<b>16 , YES), ventilation control information for controlling the air conditioner is generated based on the determined content, and recorded in the facility information/air conditioning control information DB 38 . The air conditioning control unit 30</b>F transmits the ventilation control information generated by the air conditioning control information setting unit 30</b>E to the air conditioning control device 3 through the air conditioning communication unit 31 . The air conditioning control device 3 controls the air conditioner 10 based on the ventilation control information to send out an air flow for ventilation (step S17). When the air conditioning control unit 30F can directly control the air conditioner 10, the air conditioning control unit 30F controls the air conditioner 10 based on the ventilation control information, and causes an airflow for ventilation to be sent out from the air outlet of the air conditioner 10.

On the other hand, if the ventilation conditions are not satisfied (step S16, NO), the air conditioning control information setting unit 30E, based on the facility information indicating the current state of the air conditioning area 6, the resident information, and the obstacle information, If it is not possible to determine the direction, intensity, or delivery time of the airflow at which ventilation can be performed, no ventilation control information is generated.

For example, there are no vents that can be exhausted (all closed), or the opening area of the vents (vent 7, structure 8 that can be vented, windows and doors) is smaller than a predetermined value, or it exists in the air-conditioned area 6 If the obstacle cannot be avoided by changing the delivery direction of the airflow and the airflow does not provide the desired ventilation volume, the ventilation condition is not satisfied.

In such a case, the notification unit 30H notifies the electronic device 41 used by the administrator or the management system 42 that the ventilation state is not ready through the notification control communication unit 34 and the network 40 (step S19).

In this way, when it is determined that the ventilation state is not in order based on the current situation of the air-conditioned area 6, the manager or the like is notified so that the manager can quickly adjust the ventilation state. becomes possible.

Subsequently, if there is a resident in the air-conditioned area 6 (step S18, NO), the air-conditioning control information setting unit 30E, in the same manner as described above, after the predetermined time has elapsed (step S12, YES), for the first ventilation control Collect various information to generate air conditioning control information.

It should be noted that the predetermined time (ventilation interval time) can also be varied according to the number of visitors present in the air-conditioned area 6 indicated by the visitor information. For example, when the number of people staying is large, the need for ventilation increases, so the predetermined time (ventilation interval time) is shortened according to the increase in the number of people staying, for example.

Accordingly, it is possible to generate the air conditioning control information for the first ventilation control at appropriate time intervals and appropriately perform ventilation according to the conditions of the air conditioning area 6 .

On the other hand, if it is determined that there is no resident in the air-conditioned area 6 (step S18, YES), the air-conditioning control information setting unit 30E stores various information to generate air-conditioning control information for the second ventilation control. collect. That is, the same processing as the above-described processing for the first ventilation control (steps S13 to S15) is executed (steps S20, S21, S22). Here, detailed description is omitted assuming that the same processing as described above is executed.

However, since the processing is performed when there is no resident in the air-conditioned area 6, the processing related to the resident is not included. In addition, in the second ventilation control, ventilation control information that completes the ventilation of the air-conditioned area 6 in a short period of time, which is different from the first ventilation control, is set. For example, the air volume may be set to be stronger than the air volume when there is a resident in the first ventilation control, or the number of air conditioners 10 to be operated for ventilation may be increased.

When the air conditioning control information setting unit 30E sets the ventilation control information for when there is no resident, the air conditioning control unit 30F causes the air conditioner 10 to perform an operation for ventilation based on this ventilation control information. (Step S25).

The air conditioning control unit 30F causes the air conditioner 10 to perform the ventilation operation until it is determined that the ventilation is completed. In determining whether ventilation is completed, the ventilation time may be determined by the air conditioning control information setting unit 30E. set temperature for the room temperature) to the ambient temperature (the temperature that is not cooled/heated) (a state in which the entire air in the air-conditioned area 6 is replaced).

Note that when a resident is detected in the air-conditioned area 6 (when a person enters the room) during execution of ventilation by the second ventilation control (step S27, YES), the process returns to step S13, and the first Move to processing for ventilation control.

Also, when setting the air conditioning control information for the second ventilation control by the air conditioning control information setting unit 30E, in the same way as in the case of the first ventilation control, if the ventilation conditions are not satisfied (step S23, NO), notification The unit 30H notifies the electronic device 41 used by the administrator or the management system 42 that the ventilation state is not ready through the notification control communication unit 34 and the network 40 (step S24).

In this way, the air-conditioning management device 200 in the present embodiment can perform airflow according to the position of the airflow outlet, the position of the structure capable of exhausting air, and the state of objects (obstacles, occupants, etc.) existing in the facility. , it is possible to deliver an airflow suitable for ventilation in the facility.
