(2-2) Air-conditioning control apparatus Next, the structure of the air-conditioning control apparatus 3 is demonstrated using FIGS. As illustrated in FIG. 6, the air conditioning control device 3 includes a communication unit 31, an operation panel 32 (corresponding to a display unit and a reception unit), a storage unit 33, and a control unit 35.

[Communication Department]
The communication unit 31 is a communication interface for communicating with the indoor units 2a to 2d. For example, the communication unit 31 can receive the indoor temperature detected by the indoor temperature sensor 25 of the indoor units 2a to 2d from the indoor units 2a to 2d. Moreover, the communication part 31 can transmit the operation instruction | indication of each indoor unit 2a-2d, the instruction | indication for controlling a wind direction, etc. to each indoor unit 2a-2d.

〔control panel〕
The operation panel 32 is a touch panel including, for example, a liquid crystal display and a matrix switch, and can display various screens and can receive various instructions.

  Here, the screen displayed by the operation panel 32 includes a layout screen p1 in the building RA including the air-conditioning target zones zo11 to zo44 as shown in FIG. On the layout screen p1, air-conditioning target zones zo11 to zo44 are displayed so as to be selectable. More specifically, in the layout screen p1 of FIG. 7, in addition to the air-conditioning target zones zo11 to zo44, the conditioned air supplied from the indoor units 2a to 2d together with the installation positions of the indoor units 2a to 2d in the building RA. Are displayed as airflow images im1, im2, im3,... Here, in the airflow images im1, im2, im3,..., The wind direction is indicated by the direction of the arrow extending from each outlet 21a-21d of each of the indoor units 2a-2d, and the air volume is indicated by the thickness of the arrow. Yes. For example, in the airflow image im1, since a relatively thick arrow is displayed upward from the air outlet 21a of the indoor unit 2a, conditioned air having a high air volume is blown in the direction of the air-conditioning target zones zo11 and zo21. I understand. In the layout screen p1 in FIG. 7, a table located in the air-conditioning target zone to which the air-conditioned air is to be applied so that the air-conditioning target zone that requires the supply of air-conditioned air and the air-conditioning target zone that does not require the supply of air-conditioned air can be distinguished. Are indicated by diagonal lines, and the tables located in the air-conditioning target zone where the air-conditioning air is not applied are indicated in white. Further, in the layout screen p1 of FIG. 7, the absent table is filled and displayed so that it can be distinguished whether or not it is the absent table. Furthermore, in the layout screen p1 of FIG. 7, the indoor units 2a to 2c that are in operation are shaded to indicate the indoor units 2a to 2c that are in operation and the indoor unit 2d that is in operation are stopped. The machine 2d is displayed in white.

  In the present embodiment, the installation positions of the air conditioning target zones zo11 to zo44 and the indoor units 2a to 2d on the layout screen p1 (that is, information on the layout screen p1 excluding the airflow images im1, im2, im3,...). For example, the case where the air-conditioning system 1 is registered in advance before the air-conditioning system 1 is actually used by a contractor of the air-conditioning system 1 is taken as an example. Specifically, when the air-conditioning system 1 is installed, the contractor designs coordinate data representing the positions of the indoor units 2a to 2d, the positions of the tables Ta11 to Ta44, the positions of the chairs, and the like in the building RA. It is created based on a drawing or the like, and the created coordinate data is input to the air conditioning control device 3 via a flash memory or a communication network (not shown). In addition to the above-described coordinate data, the contractor sets the height from the floor in the building RA to the lower surfaces of the indoor units 2a to 2d (that is, the height from the floor to the ceiling), and the tables Ta11 to Ta44 to the indoor units 2a to 2a. The height to the lower surface of 2d is also input to the air conditioning control device 3 in advance together with the coordinate data. Information in the layout screen p1 excluding the airflow images im1, im2, im3,... (Specifically, the air conditioning target zones zo11 to zo44 and the indoor units 2a to 2d) based on various data input by the contractor in this way. Is installed in the air conditioning control device 3 as data that can be displayed on the air conditioning operation panel 32 from the start of use of the air conditioning system 1. The airflow images im1, im2, im3,... Are in addition to the information already input at the start of operation of the indoor units 2a to 2d, and the wind direction and air volume set in the indoor units 2a to 2d. And is displayed on the layout screen p1 together with the above information.

  Further, when any of the air-conditioning target zones zo11 to zo44 is selected by contacting the pen-type pointing device de on the air-conditioning target zones zo11 to zo44 on the layout screen p1, a setting screen p2 as shown in FIG. 8 is displayed. Further displayed. The setting screen p2 according to FIG. 8 includes a “normal airflow mode” button b1, a “swirl airflow mode” button b2, an “absence” button b3, an “apply airflow” selection button b4, and an “apply no airflow” selection. A button b5, a “no smoking” button b6, and a “smoking” button b7 are all displayed so as to be selectable. Here, the “normal airflow mode” button b1 does not perform the swirling airflow for the air-conditioning target zone selected in the layout screen p1 (the air-conditioning target zone zo12 is selected in FIG. 8). This is a button for setting the “airflow mode”. The “swirl airflow mode” button b2 is a button for setting a “swirl airflow mode” for performing a swirl airflow for the selected air-conditioning target zone zo12. The “absence” button b3 is a button for setting that no person is present in the selected air-conditioning target zone zo12. The “apply airflow” selection button b4 is a button for setting airflow to the selected air-conditioning target zone zo12. In other words, “the selected air-conditioning target zone zo12 requires a supply of conditioned air” It is a button for setting “is”. The “do not apply airflow” selection button b5 is a button for performing a setting not to apply airflow to the selected air-conditioning target zone zo12. In other words, “the selected air-conditioning target zone zo12 supplies the conditioned air. This is a button for setting “It is a zone that is not required”. The “smoking” button b6 is a button for setting the selected air-conditioning target zone zo12 as a non-smoking area, and the “smoking” button b7 is a button for setting the selected air-conditioning target zone zo12 as a smoking area. It is.

  In the setting screen p2, a plurality of buttons b1 to b7 can be selected at the same time. However, in one air-conditioning target zone zo11 to zo44, an “apply airflow” selection button b4, an “not apply airflow” selection button b5, an “apply airflow” selection button b4, an “absence” button b3, “ Since the “no smoking” button b6 and the “smoking” button b7 are both mutually exclusive, it is impossible to select these combinations at the same time.

  Further, the “swirl airflow mode” button b2 can be selected when the selected air-conditioning target zones zo11 to zo44 are rectangular or square areas including all four indoor units 2a to 2d. For example, when all the zones zo11 to zo44 in the building RA are selected, the “swirl airflow mode” button b2 is in an active state. Therefore, for example, even if two zones zo11 and zo21 adjacent to each other are selected, it is impossible to realize a swirling airflow in the indoor unit 2a that mainly performs air conditioning of the zones zo11 and zo21. The airflow mode “b2” is not in an active state. That is, the “swirl airflow mode” b2 is activated only when the zones zo11 to zo44 are selected until the swirl airflow can be realized.

  According to the setting screen p2 described above, the user of the air conditioning system 1 selects the various buttons b1 to b7 on the setting screen p2 with the pointing device de, thereby setting the mode for the air conditioning target zones zo11 to zo44 selected on the layout screen p1. And absence setting, setting whether to apply airflow, setting such as non-smoking area or smoking area. Various types of information selected and set from the layout screen p1 and the setting screen p2 are received by the operation panel 32 and output to the control unit 35. That is, the operation panel 32 accepts selection of an air-conditioning target zone that requires supply of conditioned air by the indoor units 2a to 2d or an air-conditioning target zone that does not require supply of conditioned air from the layout screen p1 and the setting screen p2. It is possible to accept an air-conditioning target zone where no person is present. In particular, when the “absent” button b3 is selected on the setting screen p2, the operation panel 32 receives the air-conditioning target zone zo12 as a zone that does not require supply of conditioned air. Further, the operation panel 32 is configured to set whether or not to make a swirling airflow for the air-conditioning target zones zo11 to zo44 from the layout screen p1 and the setting screen p2, and to set the air-conditioning target zones zo11 to zo44 as a non-smoking area or a smoking area. Settings such as whether to do can be accepted.

  In the layout screen p1, the indoor units 2a to 2d themselves are also displayed so as to be selectable. Further, in the air conditioning system 1 according to the present embodiment, as will be described later in “[Determining unit]”, the air flow and the wind direction corresponding to the air flow images im1, im2, im3,... Displayed on the layout screen p1. Is basically automatically determined by a control unit 35 (described later) functioning as the determination unit 35a. However, in the operation panel 32 of the air-conditioning control apparatus 3 according to the present embodiment, the air volume among the indoor units 2a to 2d on the layout screen p1 so that the air volume and the air direction can be finely adjusted according to the user's preference. When the pointing device de touches the vicinity of the air outlets 21a to 21d where the wind direction should be finely adjusted, a screen p3 as shown in FIG. 9 is displayed on the operation panel 32. The screen p3 is a setting screen for finely adjusting the air volume with respect to the air outlet 21c of the indoor unit 2a, and is a screen used when the user adjusts the default value of the air volume according to preference. On the screen p3, an air volume setting button b8 capable of selecting four levels of air volume “strong”, “medium”, “weak”, and “stop” can be selected. Further, on the screen p3, the vertical wind direction (b9) and the horizontal wind direction (b10) of the indoor units 2a to 2d can be selected, and in particular, the vertical wind direction b9 and the horizontal wind direction according to the present embodiment. All b10 can be selected from discrete angles. As described above, the operation panel 32 receives the setting of the air volume and the air direction at the outlets 21a to 21d of the indoor units 2a to 2d from the setting screen p3, so that the air-conditioning target zones zo11 to zo44 that require supply of conditioned air are received. The user's preference for the air volume and direction of the conditioned air can be received. The set air volume and direction of the conditioned air are used as data for performing fine adjustment on the result automatically determined by the determination unit 35a described later.

The storage unit 33 is configured by, for example, an HDD or a flash memory. The storage unit 33 stores a wind direction pattern table 34 including a plurality of wind direction patterns determined by a control unit 35 (described later) functioning as the determination unit 35a.

  Here, the wind direction pattern table 34 will be described. First, the wind direction pattern is information that determines the wind direction and the like of the conditioned air blown out from each of the air outlets 21a to 21d of the indoor units 2a to 2d. As shown in FIG. 10, the wind direction pattern table 34 includes a plurality of wind direction patterns, one record of wind direction pattern ID, air conditioning target zone ID, indoor unit ID, outlet ID, flap position, louver position, wind speed, and wind temperature. It is expressed as The wind direction pattern ID is information for identifying a plurality of wind direction patterns, and different wind direction pattern IDs 101, 201, 202,... Are assigned to each wind direction pattern. In the present embodiment, the wind direction of the conditioned air is represented by the positions of the upper and lower flaps 22a to 22d (that is, the flap positions) and the positions of the left and right louvers 23a to 23d (that is, the louver positions) at the outlets 21a to 21d. Yes.

  Specifically, in the wind direction pattern table 34 of FIG. 10, the wind direction pattern corresponding to the wind direction pattern ID 101 is an example of the wind direction pattern generated when “swirl airflow mode” is selected on the setting screen p2 of FIG. ing. In particular, this wind direction pattern indicates a wind direction pattern when the swirl airflow is set for the entire building RA, and the wind direction, wind speed, and wind temperature of each of the outlets 21a to 21d in all the indoor units 2a to 2d. Etc. are included. The wind direction patterns corresponding to the wind direction pattern IDs 201, 202,... Are generated when “normal airflow mode”, “apply / do not apply airflow”, or “no smoking / smoking” is selected on the setting screen p2 of FIG. It is an example of a pattern, Comprising: The individual wind direction etc. are shown for every air-conditioning object zone zo11-zo44.

  In addition, the storage unit 33 stores the coordinate data representing the positions of the indoor units 2a to 2d in the building RA, the positions of the tables Ta11 to Ta44, the positions of the chairs, and the like input by the contractor, and the floor unit in the building RA to the indoor unit 2a. In a storage area separate from the wind direction pattern table 34, the height from the bottom surface of the ˜2d (ie, the height from the floor to the ceiling), the height from the table Ta11 to Ta44 to the bottom surface of the indoor units 2a to 2d, etc. Remember.

(Control part)
The control unit 35 is a microcomputer including a CPU and a RAM, and is connected to the communication unit 31, the operation panel 32, and the storage unit 33 as shown in FIG. The control unit 35 controls each of these connected devices. For example, the control unit 35 performs communication control of the communication unit 31 and display operation control of the operation panel 32.

  In particular, the control unit 35 according to the present embodiment performs determination of the wind direction pattern and air conditioning control of the indoor units 2a to 2d. In order to perform such an operation, the control unit 35 functions as a determination unit 35a and an air conditioning control unit 35b.

[Decision part]
The determination unit 35a determines the wind direction pattern based on the selection result of the air-conditioning target zones zo11 to zo44 received by the operation panel 32. Specifically, when an air-conditioning target zone that requires supply of conditioned air is selected via the operation panel 32, the determination unit 35a performs air-conditioning on the selected zone based on the position information of the selected air-conditioning target zone. The indoor units 2a to 2d capable of supplying air are determined. That is, the determination unit 35a specifies the nearest outlets 21a to 21d from the information (that is, the coordinate data) indicating the position in the building RA where the selected air-conditioning target zone is located, and specifies the specified outlet 21a. The indoor units 2a to 2d having ~ 21d are determined. Next, the determining unit 35a performs various types such as the height from the determined indoor units 2a to 2d to the tables Ta11 to Ta44 installed in the air conditioning target zone, the height from the floor to the ceiling in the building RA, and the like. Using the data, the positions of the upper and lower flaps 22a to 22d and the positions of the left and right louvers 23a to 23d are determined. Furthermore, the determination part 35a determines the air volume which blows off from each blowing outlet 21a-21d using the default value of air volume.

  In addition, when the air volume of the conditioned air is set from the screen p3 of FIG. 9 or the like, that is, when the air volume is finely adjusted, the determining unit 35a determines the corresponding air outlet based on the content of the finely adjusted air volume. The default value of the air volume blown out from 21a to 21d is changed. The changed airflow value is updated as a default value.

  In addition, when an air-conditioning target zone that does not require the supply of conditioned air is selected via the operation panel 32, the determination unit 35a enters and leaves the conditioned air between the zone and the air-conditioning target zone that requires the supply of conditioned air. A wind direction pattern including a so-called air curtain airflow is determined. Specifically, it is assumed that zo11, zo12, zo21, and zo22 are selected as air-conditioning target zones that do not require supply of conditioned air. In this case, as shown in FIG. 11, the determining unit 35a blows out cold air almost directly from the outlets 21c and 21d of the indoor unit 2a located in the selected air conditioning target zones zo11, zo12, zo21, and zo22. Air curtain airflow), the airflow direction pattern is determined so that airflow of “weak” airflow is blown out from the air outlet 21b of the indoor unit 2b and the air outlet 21a of the indoor unit 2c. That is, the deciding unit 35a sets the mutual flap angle so that the airflow in the downward direction is generated by colliding the cooling airflow blown out from the indoor unit 2a and the airflow of the adjacent indoor units 2b and 2c. The wind direction pattern that pushes the dust inside is determined. As described above, when the air-conditioning target zone that does not require the supply of conditioned air is selected, when the “do not apply airflow” selection button b5 is selected on the setting screen p2 in FIG. 8, the absence button For example, when b3 is selected.

  Further, when the swirling airflow mode is set for the air-conditioning target zones zo11 to zo44 from the layout screen p1 of FIG. 7 and the setting screen p2 of FIG. 8, the determining unit 35a forms the swirling airflow for all the air-conditioning target zones zo11 to zo44. Determine the wind direction pattern. That is, when the “swirl airflow mode” button b2 is selected on the setting screen p2, the determination unit 35a determines a wind direction pattern as indicated by the wind direction pattern ID 101 in the wind direction pattern table 34 of FIG. With this wind direction pattern, a swirling airflow as shown in FIG. 12 is formed in the building RA from the indoor units 2a to 2d. However, as described above, the control in the swirl airflow mode is performed when the selected air-conditioning target zones zo11 to zo44 are rectangular or square areas including all the four indoor units 2a to 2d. .

  When the normal airflow mode is set for the air-conditioning target zones zo11 to zo44 from the layout screen p1 in FIG. 7 and the setting screen p2 in FIG. 8 (that is, the “normal airflow mode” button b1 on the setting screen p2 is selected. ), The determination unit 35a makes other settings (specifically, the “apply airflow” selection button b4, the “do not apply airflow” selection button b5, etc. on the other selected setting screen p2). To determine the wind direction pattern. For example, if the “normal airflow mode” button b1 and the “apply airflow” selection button b4 are simultaneously selected on the setting screen p2 of FIG. 8, the determination unit 35a first selects the air-conditioning target zone selected. A wind direction pattern in which conditioned air is supplied to zo11 to zo44 is determined, and normal conditioned air that is not a swirling airflow or the like is supplied after a certain period of time has elapsed since the start of airflow control based on this wind direction pattern. Determine the wind direction pattern. That is, the determination unit 35a first determines a wind direction pattern corresponding to the “apply airflow” selection button b4, and then determines a wind direction pattern corresponding to the “normal airflow mode” button b1. When only the “normal air flow mode” button b1 is selected, the determination unit 35a determines the wind direction pattern so that PID control is performed for the selected air-conditioning target zones zo11 to zo44.

  Further, when the air-conditioning target zone to be set as the non-smoking area or the air-conditioning target zone to be set as the smoking area is set from the layout screen p1 and the setting screen p2 in FIG. 8 (that is, the “no-smoking” button b6 on the setting screen p2). Or, when the smoking button b7 is selected), the determination unit 35a determines a wind direction pattern that makes it difficult for smoke from the air-conditioning target zone to be the smoking area to flow into the air-conditioning target zone to be the non-smoking area. . For example, when the smoking button b7 is selected for the air-conditioning target zones zo11, zo12, zo21, and zo22 via the operation panel 32, the determination unit 35a is the same as the case where the “do not apply airflow” setting is made. The wind direction pattern as shown in FIG. 11 is determined. That is, the determination unit 35a enters the air-conditioning target zones zo11, zo12, zo21, and zo22, which should be designated as non-smoking areas, with the conditioned air from the air-conditioning target zones zo13, zo14, zo23, zo24, and zo31 to zo44 that are smoking areas In order to avoid this, a wind direction pattern is determined such that the air-conditioning target zones zo11, zo12, zo21, zo22 and the air-conditioning target zones zo13, zo14, zo23, zo24, zo31 to zo44 are blocked by cold air.

  The wind direction pattern determined as described above is written into the wind direction pattern table 34 of FIG. 10 by the determination unit 35a.

  In the present embodiment, as described above, among the buttons b1 to b7 on the setting screen p2, the “apply airflow” selection button b4, the “do not apply airflow” selection button b5, and the “apply airflow” The combination of the “selection button b4 and“ absence ”button b3, the“ no smoking ”button b6 and the“ smoking ”button b7 are mutually exclusive controls, and therefore the same air-conditioning target zones zo11 to zo44. It is impossible to select at the same time. However, when the buttons b1 to b7 are selected in a combination other than the above, the determination unit 13a determines the wind direction pattern based on the priority table shown in FIG. For example, the swirl airflow mode button b2 is selected for all the air-conditioning target zones zo11 to zo44, and at the same time, the “do not apply airflow” selection button b4 is selected for a predetermined zone (for example, the air-conditioning target zone zo14). If it is determined that the air flow is not supplied to the air-conditioning target zone zo14 based on the priority table shown in FIG. Determine the pattern. This is because, according to the priority order table shown in FIG. 13, the priority is higher for the “do not apply airflow” selection button b4 for each zone than for the “swirl airflow mode” button b2.

  Here, in the priority order table of FIG. 13, the types of the buttons b1 to b7 on the setting screen p2 are associated with the priority order of each button. In particular, the control corresponding to the “apply airflow / do not apply airflow” selection buttons b4 and b5 sends the wind to the user who feels hot at present and does not send the wind to the user who feels cold. Therefore, priority is set higher than other controls such as the swirl airflow mode. Among the controls, the control corresponding to the “apply airflow” selection button b4 is intended to be performed for a short time of about 10 minutes, for example. Further, the control corresponding to the “swirl airflow mode” button b2 is control for agitating the air in the zone to eliminate the temperature unevenness, and the priority is second. The control corresponding to the first priority and the second priority is canceled when, for example, the user presses the buttons b2, b4, and b5 again or presses the other buttons b3, b5 to b7. Further, in the control corresponding to the “apply airflow” selection button b4 in the first priority control and the control corresponding to the “swirl airflow mode” button b2 in the second priority, a predetermined time has elapsed. In such a case, the control is automatically canceled. For example, in the control corresponding to the “apply airflow” selection button b4, the predetermined time is set to 10 minutes. In this way, after the control is released, for the zones zo11 to zo44 for which the released control was performed until then, other buttons (for example, “absence” button b3 etc.) set at the same time are used. Corresponding control is performed. The other buttons b3, b6 to b7 are also released when the user presses the buttons b3, b6 to b7 again or presses other buttons.

  In the following, it is assumed that the “normal airflow mode” according to the present embodiment is set as a default regardless of whether or not the “normal airflow mode” button b1 is pressed.

[Air conditioning control unit]
The air conditioning control unit 35b controls the indoor units 2a to 2d based on the wind direction pattern determined by the determination unit 35a.

  For example, when the wind direction pattern ID 101 in the wind direction pattern table 34 of FIG. 10 is determined by the determination unit 35a, the air conditioning control unit 35b controls the indoor units 2a to 2d to perform a swirling airflow. When the wind direction pattern ID 201 is determined, the air conditioning control unit 35b receives the airflow “strong” from the air outlet 21a of the indoor unit 2a for the air conditioning target zone zo11 corresponding to the air conditioning target zone ID “1”. Control to blow out.

(3) Operation Next, the operation performed by the air conditioning control device 3 will be described with reference to FIGS. In the following, it is assumed that the “normal airflow mode” is set as default as already described.

  Steps S1 and S2: When the air conditioning control device 3 is turned on by the administrator of the air conditioning control device 3 (Yes in S1), the layout screen p1 is displayed on the operation panel 32 (S2). Although not shown, the air conditioning control device 3 is connected to a plurality of sensor nodes arranged in the building RA in order to detect the presence / absence of a person and the floor temperature distribution. Start monitoring results. A plurality of sensor nodes are arranged in each of the zones zo11 to zo44.

  Steps S3 to S4: At least one of the air-conditioning target zones zo11 to zo44 is selected from the layout screen p1 by the administrator or the like, and then various settings are made for the zones zo11 to zo44 selected from the displayed setting screens p2 and p3. If it is (Yes in S3), the air conditioning control device 3 performs the operations after Step S3. When the air-conditioning target zones zo11 to zo44 are not selected (No in S3), since only the “normal airflow mode” is currently set as a default, the air-conditioning control unit 35b performs PID control. Based on this, airflow control of each indoor unit 2a-2d is performed (S4). Here, the PID control is control for reducing temperature unevenness in the building RA so as to approach the set temperature. That is, in step S4, conventional air conditioning (or uniform air conditioning) is performed in the building RA by performing airflow control of the indoor units 2a to 2d based on PID control. For example, when the temperature in the building RA approaches the set temperature, for an air conditioner that performs inverter control, the inverter frequency is decreased, and if the difference between the set temperature and the temperature in the building RA is equal to or lower than a predetermined temperature, the thermo-off is performed. Control is performed. Further, if the air conditioner is a non-inverter machine, the set temperature is compared with the temperature in the building RA, and if the difference between these temperatures is equal to or less than a predetermined temperature, the thermo-off control is performed.

  Steps S5 to S6: When the setting is made for each of the selected zones zo11 to zo44 in Step S3 (Yes in S3, that is, when one or more buttons b1 to b7 are pressed), the selection is made. If the control activation conditions corresponding to the respective buttons b1 to b7 are satisfied (Yes in S5), the control unit 35 performs the control corresponding to the buttons b1 to b7 having the highest priority shown in FIG. It performs about the blowout ports 21a-21d of the indoor units 2a-2d used as object (S6). On the other hand, in step S5, when the control activation conditions corresponding to the selected buttons b1 to b7 are not satisfied (No in S5), the operation in step S3 is repeated. Here, as the activation condition, for example, when a plurality of buttons b1 to b7 are selected in duplicate for one zone, these buttons b1 to b7 are not mutually exclusive and can be selected together. And the condition that the detection result by the sensor node monitored by the air conditioning control device 3 is in a state where the control corresponding to the button can be executed. When the activation condition as described above is satisfied, the determination unit 35a determines the wind direction pattern so as to prioritize the control with the highest priority among the controls corresponding to the selected buttons b1 to b7. To do. The air conditioning control unit 35b performs airflow control based on the wind direction pattern. For example, if the “swirl airflow mode” button b2 and the “apply airflow” selection button b4 are selected in addition to the default “normal airflow mode” for the zones zo11 to zo24, these buttons b2, The control content corresponding to b4 is not mutually exclusive. Therefore, the control unit 35 first performs the airflow control based on the high priority “apply airflow” selection button b4 for the outlets 21a to 21d of the indoor units 2a to 2d that send the conditioned air to the zones zo11 to zo24. Do.

  Step S7: The control unit 35 performs airflow control according to the set priority order for the other outlets 21a to 21d that do not affect the control of Step S6. That is, airflow control that is a lower order than the priority order of step S6 is performed for the other outlets 21a to 21d that do not affect the control of step S6.

  Steps S8 to S9: When a predetermined condition such as a predetermined time has elapsed since the current air flow control is started (Yes in S8), the control unit 35 determines whether the predetermined condition is satisfied. For 21d, control corresponding to the priority order (that is, control different from the previous control) is performed (S9). For example, for the zones zo11 to zo24, in addition to the default “normal airflow mode”, the “swirl airflow mode” button b2 and the “apply airflow” selection button b4 are selected. The air flow control based on the “apply air flow” selection button b4 is performed, but when a predetermined time has elapsed since the start of the air flow control, the control unit 35 selects the selected zone. Airflow control is performed in the swirl airflow control mode, which has a lower priority than “applying airflow”, to the outlets 21a to 21d of the indoor units 2a to 2d that have applied airflow to zo11 to zo24. In addition, as another example of the predetermined condition in step S8, the detection result by the sensor node monitored by the air conditioning control device 3 can execute control corresponding to the selected buttons b1 to b7 as in the case of the activation condition. The condition which became a state is mentioned.

  Steps S10 to S11: The zone and the setting related to Step S3 are selected by selecting a different zone from the zone selected in Step S3 or selecting a button different from the button selected in Step S3. Unless changed (No in S10), the air-conditioning control device 3 repeats the operations after step S8. Even after step S4, and even when the zone and setting are changed (Yes in S10), the air conditioning control device 3 repeats the operation after step S5 until the power is turned off (No in S11). When the power is turned off (Yes in S11), the air conditioning control device 3 ends the series of operations.

(4) Specific Examples of Airflow Control Specific examples A to C of airflow control according to the air conditioning system 1 will be described below.

(4-1) Specific example A
FIG. 16 shows an example in which the air conditioning system 1 according to the present embodiment is used for airflow control in a sushi restaurant. 16 (a) to 16 (c) show, in order, a time zone in which the seating rate is about 25%, a time zone from 10:30 to 11:30 and 15:00 to 16:00 on weekdays (attention rate of about 50%), It represents the state in the store on the weekends and holidays (specifically, Friday, Saturday, Sunday) from 12:00 to 13:00 and from 17:00 to 19:00 (at a seating rate of about 100%). In addition, in Fig.16 (a)-(c), the indoor units 2a-2d in operation shall be performing air_conditionaing | cooling operation. In this store, it is assumed that customers who visit the store are guided in order from the upper left area in the building RA.

  First, as shown in FIG. 16 (a), when the customer is present only in the upper left area in the store, the store clerk displays the layout screen p1 displayed on the operation panel 32 of the air conditioning control device 3 and Using the setting screen p <b> 2, “absent” is set for other areas where there are no customers. Then, the air-conditioning control device 3 determines the wind direction pattern so that the conditioned air is supplied to the upper left area where the customer is present but the conditioned air is not supplied to other areas where the customer is not present. The air conditioning operation as shown in Fig. 2 is performed by each of the indoor units 2a to 2d. That is, the indoor unit 2a blows out conditioned air in four directions, but the indoor units 2b and 2c blow out an air curtain airflow from a blowout port located on the indoor unit 2a side. Thereby, compared with the case where all the indoor units 2a-2d perform weak cooling, the energy consumed by the indoor units 2a-2d can be suppressed, for example, by about 20%.

Next, as shown in FIG. 16 (b), when the customer is present in the left area of the store, the store clerk of the store displays the layout screen p <b> 1 displayed on the operation panel 32 of the air conditioning control device 3 and the setting. Using the screen p2, “absent” is set for the right area where there is no customer. Then, the air conditioning control device 3 determines the wind direction pattern so that the conditioned air is supplied to the left area where the customer is present but the conditioned air is not supplied to the right area where there is no customer. The air conditioning operation as shown is performed by each of the indoor units 2a to 2d. That is, the indoor units 2a and 2c blow out the conditioned air in four directions, but the indoor units 2b and 2d blow out an air curtain airflow from the respective outlets located on the indoor units 2a and 2c side. Thereby, compared with the case where all the indoor units 2a-2d perform weak cooling, the energy consumed by the indoor units 2a-2d can be suppressed by about 10%, for example.

  Next, as illustrated in FIG. 16C, when the customer is present throughout the store, the store clerk displays the layout screen p <b> 1 and the setting screen p <b> 2 displayed on the operation panel 32 of the air conditioning control device 3. Is used to set the “swirl airflow mode” for all areas in the store. Then, the air-conditioning control apparatus 3 and the wind direction pattern in which PID control is performed in all the indoor units 2a to 2d (FIG. 16 (c-1), that is, the wind direction pattern corresponding to the default “normal air flow mode”). , A wind direction pattern (FIG. 16 (c-2), that is, a wind direction pattern corresponding to the set “swirl air flow mode”) that swirls the air flow by changing the air outlets 21 a to 21 d that blow out the conditioned air over time; At the same time, control is performed so that these are switched appropriately. More specifically, after the air flow control of the indoor units 2a to 2d based on the PID control is performed for 1 hour, the swirling air flow control is performed for about 10 minutes, and then the air flow control based on the PID control is performed again. The switching is repeated. As a result, even if cold air accumulation occurs due to the conventional airflow control based on PID control (FIG. 16 (c-1)), and as a result, temperature unevenness occurs in the store, the temperature is controlled by the swirling airflow that is appropriately implemented. Unevenness is eliminated. That is, by rotating the air flow as shown in FIG. 16 (c-2), the temperature of the entire room is periodically agitated, so that the temperature unevenness is eliminated. Moreover, the energy consumed by the indoor units 2a to 2d can also be suppressed.

  Thus, according to the air conditioning system 1 according to the present embodiment, the store clerk and the like can be used to appropriately switch the wind direction pattern according to the congestion of the store that changes over time. Thereby, while being able to maintain the comfortable seat of the customer who visited the store, the maximum energy-saving driving | operation corresponding to a store can be performed.

(4-2) Specific example B
FIG. 17 shows an example when the air conditioning system 1 according to the present embodiment is used for airflow control in a family restaurant store. In FIGS. 17 (a) and 17 (b), it is assumed that the indoor units 2a to 2d that are in operation are performing a cooling operation as in FIGS. 16 (a) to 16 (c).

  By the way, generally, in a restaurant of a family restaurant, a smoking area and a non-smoking area are often fixed. Therefore, for example, when the attendance rate in the smoking area and the non-smoking area is 50% and 100%, respectively, and the customer who visited the store is a non-smoking person, there is a vacant table in the smoking area. Because there is no vacant table, the customer cannot be guided immediately.

  On the other hand, when the air conditioning system 1 according to the present embodiment is used, the areas of the smoking area and the non-smoking area can be changed according to the customers who visit the store from time to time. For example, as shown in FIG. 17A, when a customer who is a non-smoking person visits a store in a state where the attendance rate in the non-smoking area is 100%, the store clerk operates the air-conditioning control device 3. Using the layout screen p1 and the setting screen p2 displayed on the panel 32, “no smoking” is set for the zone including the vacant seat tables TaA and TaB in the smoking area. Then, the air-conditioning control device 3 determines the wind direction pattern so that the conditioned air from the smoking area does not easily flow into the zone including the selected tables TaA and TaB and the non-smoking area until then, as shown in FIG. The air conditioning operation as shown in b) is performed by each of the indoor units 2a to 2d. That is, the indoor unit 2b blows out an air curtain airflow from the air outlet near the non-smoking area side, that is, the indoor unit 2a side, toward the non-smoking area side. The indoor unit 2d stops the air curtain airflow toward the zone including the tables TaA and TaB, and supplies conditioned air having a high air volume to the zone including the tables TaA and TaB. The indoor units 2a and 2c continuously perform the air conditioning operation similar to that in FIG. As a result, the zone including the tables TaA and TaB that were previously included in the smoking area has been changed from the “smoking” setting to the “no smoking” setting. It becomes difficult to leak. Therefore, if the store side has a vacant seat, it can guide smoothly without waiting for the customer, so the turnover rate of the customer in the store is improved.

(4-3) Example C
FIG. 18 shows an example in which the air conditioning system 1 according to the present embodiment is used for airflow control in a business office. 18 (a) and 18 (b), as in FIGS. 16 (a) to 16 (c) and FIGS. 17 (a) and 17 (b), the indoor units 2a to 2d being operated are performing a cooling operation. To do.

  For example, as shown in FIG. 18A, when the attendance rate in the sales office is close to 100%, a hot employee or a cold employee may be mixed. In this case, each employee confirms the wind direction and the air volume by the air flow images im1, im2,... On the layout screen p1 displayed on the operation panel 32 of the air conditioning control device 3. When each employee wants to set the desired conditioned air, he selects the air-conditioning target zone including his / her seat from the air-conditioning target zones zo11 to zo44 on the layout screen p1, and then sets the setting screen p2. , P3 are used to change the setting of “do not apply airflow” or “apply airflow”, and the wind direction and air volume. Then, the air-conditioning control device 3 generates a wind direction pattern that supplies airflow of “strong” air volume to the selected air-conditioning target zone, or a wind direction pattern that prevents airflow from being applied to the selected air-conditioning target zone. decide. For this reason, for example, the air conditioning operation as shown in FIG. 18A is performed by each of the indoor units 2a to 2d. In FIG. 18A, the conditioned air is not supplied to the air-conditioning target zone including the seat of the employee shA, and the airflow of “strong” is blown in four directions to the other air-conditioning target zones. An example is shown. As a result, conditioned air is supplied to each zone as set for each zone, so that everyone in the business office can spend comfortably.

  Next, as shown in FIG. 18 (b), when many employees leave their seats, the area is 25%, and the seating rate is less than about 33%, From the layout screen p1 and the setting screens p2 and p3 displayed on the operation panel 32 of FIG. 3, “absent” is set for the zone where the employee is absent, and each area in the area sq where the employee is present is set. For the zone, set the air volume “weak”. Here, the “absent” setting includes, for example, a setting in which the set temperature is increased by 1 ° C. in the area sq to which the conditioned air of “low” air volume is supplied. Then, the air-conditioning control device 3 is supplied with airflow of “weak” air volume to the area sq where the employee is present and the set temperature is set to 1 ° C. higher, but is set for other areas where no employee is present. Indoor unit 2c-2d will be in a thermo-off state, without temperature changing. Therefore, the air conditioning operation as shown in FIG. 18B is performed by each of the indoor units 2a to 2d. In other words, the indoor unit 2a blows out the conditioned air with the air volume “weak” in four directions, but the indoor units 2b and 2c blow out the air curtain airflow from the outlet located on the area sq side. As a result, the conditioned air from the indoor unit 2a is distributed in the area sq. Therefore, even if the set temperature of the indoor unit 2a is high, the air-conditioned air can be supplied to the area sq where the employee is present, so that the comfort of the employee in the area sq is ensured. . In addition, since air conditioning can be performed according to the number of employees present at that time, the energy consumed by the indoor units 2a to 2d is less than when all of the indoor units 2a to 2d perform weak cooling. For example, it can be suppressed by about 20%.

(5) Effect (A)
According to the air conditioning system 1 according to the present embodiment, on the operation panel 32, for example, a plurality of air conditioning target zones zo11 to zo44 defined based on the arrangement of tables Ta11 to Ta44 and chairs in the building RA can be selected. A layout screen p1 is displayed. And the air-conditioning object zone which should supply conditioned air by the user of the air-conditioning system 1 and / or the air-conditioning object zone which should not supply conditioned air are selected, and, thereby, each direction of the indoor unit 2a-2d The air direction of the conditioned air blown from the ports 21a to 21d is determined. Thereby, the user can easily instruct fine airflow control according to the environment in the building RA from the layout screen p1. Therefore, the operability in setting the wind direction and the like of each air conditioning unit is improved.

(B)
Moreover, according to the air conditioning system 1 which concerns on this embodiment, while displaying the position of indoor unit 2a-2d installed in building RA on the layout screen p1, it is supplied from each indoor unit 2a-2d. An airflow image im1, im2,... Indicating the wind direction and air volume of the conditioned air is displayed. Accordingly, the user can know from the layout screen p1 what position the indoor units 2a to 2d are arranged in the building RA and what direction the conditioned air is blown in which direction.

(C)
Further, according to the air conditioning system 1 according to the present embodiment, the layout screen p1 displays the air-conditioning target zone that does not require the supply of conditioned air and the air-conditioning target zone that requires the supply of conditioned air in a distinguishable manner. Therefore, the user can easily know the air-conditioning target zone that does not require the supply of conditioned air and the air-conditioning target that requires the supply of conditioned air.

(D)
Moreover, according to the air conditioning system 1 which concerns on this embodiment, the air-conditioning control apparatus 3 can accept the air-conditioning object zone where a person is absent as an air-conditioning object zone which does not require supply of conditioned air. When the user selects an air-conditioning target zone in which no person is present, the indoor units 2a to 2d can stop the supply of conditioned air to the air-conditioning target zone in which no person is present. The energy consumed by can be suppressed.

(E)
Further, in the air conditioning system 1 according to the present embodiment, the user can set one of the swirling airflow mode for forming the swirling airflow and the normal airflow mode not forming the swirling airflow for the air conditioning target zones zo11 to zo44. Therefore, temperature unevenness in the building RA can be eliminated.

(F)
Moreover, according to the air conditioning system 1 according to the present embodiment, when an air-conditioning target zone that does not require the supply of conditioned air is selected, the conditioned air does not enter and exit between this zone and the zone that requires the supply of conditioned air. In addition, the indoor units 2a to 2d are controlled. Specifically, the indoor units 2a to 2d installed in the air-conditioning target zone that requires the supply of conditioned air, and the indoor units 2a to 2d installed in the air-conditioning target zone that do not require the conditioned air adjacent to the zone. Both sides can cooperate to generate an airflow that hardly discharges the cold air. Thereby, for example, it is possible to prevent the cold air from the cooling operation from leaking into a zone that does not require the supply of conditioned air.

(G)
Moreover, according to the air conditioning system 1 which concerns on this embodiment, the user can select the air-conditioning object zone which should be made into a non-smoking area, or the air-conditioning object zone which should be made into a smoking area. Thereby, for example, airflow control is performed such that the entry and exit of conditioned air between the smoking area and the non-smoking area is blocked. Therefore, the building RA can be easily made into a non-smoking area or a smoking area according to the person in the building RA.

(H)
Further, according to the air conditioning system 1 according to the present embodiment, the user can set the air volume of the conditioned air to the air-conditioning target zone that needs to be supplied with conditioned air, for example, “weak” or “strong”. Therefore, the air-conditioning air of the air volume according to the user's preference is sent to each of the air-conditioning target zones zo11 to zo44.

(I)
Further, in the air conditioning system 1 according to the present embodiment, when an air-conditioning target zone that requires supply of conditioned air is selected, an indoor space that can supply conditioned air to this zone based on the position information of the selected air-conditioning target zone Units 2a to 2d are determined, and wind direction patterns for the determined indoor units 2a to 2d are determined. That is, conditioned air is supplied from the indoor units 2a to 2d disposed in or near the zone to be conditioned that requires supply of conditioned air. Accordingly, the conditioned air is sent from the outlets 21a to 21d at the optimum positions to the air-conditioning target zone that is selected as requiring the supply of conditioned air.

<Other embodiments>
(A)
In the above embodiment, as shown in FIG. 3, the case where the air-conditioning target zones zo11 to zo44 are defined in a range surrounding a table and four chairs installed around the table has been described. However, the definition of the air-conditioning target zones zo11 to zo44 is not limited to this. For example, the air-conditioning target zone is defined by the position of the chair installed in the building RA, or the building RA is simply divided into a plurality of sections regardless of the position of the chair or table, and each section is divided into one air-conditioning target zone. Or may be defined as In addition, the air conditioning target zone may be defined within a predetermined range based on one indoor unit.

(B)
Moreover, in the said embodiment, when the whirling airflow mode is selected, as shown by the wind direction pattern ID101 in the wind direction pattern table 34 of FIG. 10, when all the indoor units 2a-2d perform a whirling airflow (that is, a building) A description has been given of the case where the swirling airflow is performed in the entire RA, that is, in all air-conditioning target zones zo11 to zo44. However, in the swirl airflow mode, in addition to the swirl airflow being performed for all the air-conditioning target zones zo11 to zo44, the swirl airflow may be partially performed for the plurality of selected air conditioning target zones zo11 to zo44. However, the partial swirling airflow is also performed when the condition that a plurality of air-conditioning target zones zo11 to zo44 capable of executing the swirling airflow are selected is satisfied, as in the above embodiment.

  In the above embodiment, when the selected air-conditioning target zones zo11 to zo44 are rectangular or square areas including all four indoor units 2a to 2d, the “swirl airflow mode” button b2 is selected. I explained that it would be possible. However, the condition that enables the “swirl airflow mode” button b2 to be selected is not limited to this. For example, if the indoor units 2a to 2d can be directly selected from the layout screen p1 displayed on the operation panel 32, there are four selected indoor units 2a to 2d and all the selected indoor units. When the air-conditioning target area formed by 2a to 2d is a rectangle or a square, the “swirl airflow mode” button b2 may be selectable.

  Thus, in view of the setting conditions of the swirling airflow mode, the above-described method (that is, the method of selecting the indoor units 2a to 2d) is compared to the method of selecting the air-conditioning target zones zo11 to zo44 as in the above embodiment. Thus, the swirl airflow mode can be easily set. In the method of selecting the air-conditioning target zones zo11 to zo44, the smaller the range of one air-conditioning target zone, the larger the number of zones that should be selected to activate the “swirl airflow mode” button b2. Because.

(C)
Moreover, in the said embodiment, when the "swirl air current mode" was set via the operation panel 32 of the air-conditioning control apparatus 3, the case where a swirl air current was performed was described. However, the swirl airflow control may be performed automatically.

  In this case, for example, an infrared sensor for detecting the temperature near the person or the floor is arranged in each air-conditioning target zone zo11 to zo44 of the building RA. The air conditioning control device 3 obtains the difference between the detection result for each air conditioning target zone zo11 to zo44 by the infrared sensor and the suction temperature of each of the indoor units 2a to 2d corresponding to each zone zo11 to zo44 every predetermined time. If the location where the obtained difference is, for example, 4 degrees or more is about 50% or more of the total, the air conditioning control device 3 may cause the indoor units 2a to 2d to perform a swirling airflow.

  A wireless sensor may be used instead of the infrared sensor.

(D)
In the above-described embodiment, the case where the absent air-conditioning target zone is selected by the user from the layout screen p1 displayed on the operation panel 32 has been described. However, the method of setting the air conditioning target zone that is absent may be other than this.

  For example, a sensor for detecting a person is arranged in each air conditioning target zone zo11 to zo44 of the building RA in consideration of the detectable range of the sensor. The air-conditioning control device 3 grasps the number of people in each air-conditioning target zone zo11 to zo44 every predetermined time, for example, 10 minutes from the detection result of the sensor, and determines whether or not there is an air-conditioning target zone without people. to decide. When the air conditioning control device 3 determines that there is an air conditioning target zone without a person, the air conditioning control unit 3 stops air conditioning to the air conditioning target zone for the indoor unit that air-conditions the air conditioning target zone and is adjacent to the air conditioning target zone. The wind direction pattern is determined so that the conditioned air is supplied to the zone. As described above, it is possible to eliminate the useless indoor unit by performing the air conditioning operation by determining whether or not there is an air conditioning target zone without a person using the sensor.

  Further, instead of arranging the sensors in the respective air-conditioning target zones zo11 to zo44, the air-conditioning control device 3 obtains, for example, login information from a plurality of PCs arranged in the respective zones zo11 to zo44, so It may be determined whether or not there is a zone.

(E)
The air-conditioning system 1 according to the above embodiment may automatically perform air-conditioning control according to the preference of each person in the building RA, in addition to air-conditioning control for each of the air-conditioning target zones zo11 to zo44. Good. In this case, a sensor node for detecting the temperature and / or humidity in the vicinity of the chair is arranged near the chair where the person is seated, and a chair ID is assigned to each chair for convenience of control. . When the air conditioning control device 3 acquires the detection result of the sensor node, the position of the chair near the installation position of the sensor node, the chair ID corresponding to the chair, and the detection result of the sensor node (that is, the temperature near the chair and / or Or, the wind direction patterns 301 and 302 including the wind direction and the air volume are determined from the pre-stored preference information of the seated person (see FIG. 19). That is, the wind direction patterns corresponding to the wind direction pattern IDs 301, 302,... In FIG. 19 indicate so-called personal air conditioning patterns, such as whether to provide conditioned air to each individual seated on the chair. In this case, the wind direction pattern table 34 ′ stored in the storage unit 33 of the air conditioning control device 3 has one record of the chair ID in addition to the wind direction pattern ID, the zone ID, the indoor unit ID, etc. in the wind direction pattern table 34 of FIG. It is expressed as Thereby, the air-conditioning system 1 can automatically provide conditioned air according to each individual's preference.

  Note that the air conditioning control device 3 uses the login information of the PC operated when a person sits on the chair, not on the detection result by the sensor node, for determining whether or not a person is seated on the chair. You may go. Further, the air conditioning control device 3 reads RFID tag information held by a person with a tag reader provided in the building RA, and determines whether or not a person is seated based on the read information. Also good.

(F)
In the above embodiment, the case where the four indoor units 2a to 2d are arranged in the building RA as shown in FIG. 2 has been described. However, the number of indoor units arranged in the building RA is not limited to four, and the installation position is not limited to FIG. 2 and may be arranged in any manner.

(G)
In the above embodiment, the case where the indoor units 2a to 2d are ceiling embedded type indoor units has been described as an example. However, the indoor unit according to the present invention is not limited to the ceiling-embedded type, and may be a ceiling-suspended type, a duct type (ceiling blowout, floor blowout) type, or the like as long as the wind direction and wind speed can be controlled for each blowout opening. Any type of indoor unit may be used.

(H)
In the above embodiment, before the air conditioning system 1 is actually used, the installation positions of the air conditioning target zones zo11 to zo44 and the indoor units 2a to 2d on the layout screen p1, that is, the airflow images im1, im2, and so on. Information on the layout screen p1 excluding im3... is input to the air conditioning control device 3, and the airflow images im1, im2, im3... are determined each time when the indoor units 2a to 2d are operated. It has been described that the information is displayed on the layout screen p1 together with the information. However, the installation positions of the air-conditioning target zones zo11 to zo44 and the indoor units 2a to 2d on the layout screen p1 are not input to the air conditioning control device 3 in advance as usable data, but airflow images im1, im2, and im3. .. May be determined each time the layout screen p1 is displayed.

(I)
In the above embodiment, the wind direction pattern is calculated each time the indoor units 2a to 2d are operated, and the air flow images im1, im2, im3,... Based on the wind direction pattern are displayed on the layout screen p1. explained. However, in the air conditioning system according to the present invention, the wind direction pattern may not be calculated each time. A plurality of wind direction patterns calculated in advance by a trial operation tool or the like are stored in the wind direction pattern table, and according to various contents set via the operation panel 32 and various information (such as temperature in the building RA) at that time. Thus, a method of selecting a wind direction pattern from the table may be employed. Further, the wind direction pattern may be created by combining a plurality of existing wind direction patterns in the table and used for airflow control.

  In addition, the wind direction pattern table is similar to the coordinate data according to the above-described embodiment, etc. by the air conditioning system contractor before the air conditioning system is actually used, via the flash memory or the communication network (not shown). It is input in the storage unit.

(J)
In the above embodiment, the air volume and direction corresponding to the airflow images im1, im2, im3,... In the layout screen p1 are basically automatically determined by the air conditioning control device 3, and the user uses FIG. He explained that the air volume and direction can be fine-tuned according to his / her preference. However, in the air conditioning system 1 according to the present invention, the air volume and the wind direction are automatically determined only by the air conditioning control device 3, and the fine adjustment function by the user may not be provided.

(K)
In the said embodiment, the indoor unit 2a-2d which can control a wind direction to both the vertical direction and a horizontal direction was demonstrated and demonstrated to the example. However, in the present invention, an indoor unit without lateral wind direction control may be used. In this case, when the swirling airflow is performed, the conditioned air is not supplied in an oblique direction as shown in FIG. 12, but is supplied as shown in FIG. That is, conditioned air is supplied toward adjacent indoor units, but in any indoor unit, conditioned air is supplied to different zones without overlapping zones for supplying conditioned air. FIG. 20 shows an example in which conditioned air is supplied in the counterclockwise direction.

(L)
In the above embodiment, as shown in the wind direction pattern table 34 in FIG. 10 and the wind direction pattern table 34 ′ in FIG. 19, the case where the air conditioning control device 3 can control not only the wind direction but also the wind temperature has been described. However, the air conditioning system according to the present invention only needs to execute at least wind direction control, and does not need to perform air temperature control.

(M)
In the above embodiment, when one or more buttons b1 to b7 are selected on the setting screen p2 in FIG. 8, the operations corresponding to the selected buttons are prioritized as shown in FIGS. 13) and the like. However, in the air conditioning system 1 according to the present invention, when one button is selected on the setting screen p2 in FIG. 8, all modes are selected such that no other button can be selected until the control corresponding to the button is completed. A mutual exclusion method may be adopted. 21 and 22 show the flow of operations performed by the air conditioning control device 3 when the all-mode mutual exclusion method is adopted.

  Steps S103 to S104: When any one of the air-conditioning target zones zo11 to zo44 is selected from the layout screen p1 by the administrator or the like and then various settings are made from the displayed setting screens p2 and p3 (Yes in S103) ), The air conditioning control device 3 performs the operations after step S103. When the air conditioning target zones zo11 to zo44 are not selected (No in S103), the air conditioning control unit 35b performs airflow control of the indoor units 2a to 2d based on PID control (S104).

  Steps S105 to S106: When the setting made in Step S103 is the “swirl airflow mode” setting (Yes in S105), the determination unit 35a turns the swirl airflow in the building RA as indicated by the wind direction pattern ID101 of FIG. The wind direction pattern is determined so that is formed. The air conditioning control unit 35b performs the swirl airflow control for each of the indoor units 2a to 2d based on the wind direction pattern (S106). As a result, a swirling airflow as shown in FIG. 12 is supplied to the building RA.

  Steps S107 to S108: When the setting made in Step S103 is the “absent” setting (Yes in S107), the determination unit 35a does not supply conditioned air to the air-conditioning target zone selected from the layout screen p1. A wind direction pattern for controlling the absent airflow is determined. The air conditioning control unit 35b performs absent airflow control on the corresponding indoor units 2a to 2d based on the wind direction pattern (S108). Thereby, for example, an air flow as shown in FIG. 11 is supplied to the building RA.

  Steps S109 to S110: When the setting made in step S103 is the “apply airflow” setting (Yes in S109), the determination unit 35a supplies the conditioned air to the air-conditioning target zone selected from the layout screen p1. Determine the wind direction pattern. Specifically, the determination unit 35a determines a wind direction pattern as indicated by the wind direction pattern IDs 201 and 202 in FIG. The air conditioning control unit 35b performs airflow control on the corresponding indoor units 2a to 2d based on the wind direction pattern (S110).

  Steps S111 to S112: When the setting made in step S103 is “do not apply airflow” (Yes in S111), the determination unit 35a determines the conditioned air for the air-conditioning target zone selected on the layout screen p1. The wind direction pattern is determined so that is not supplied. That is, the determination unit 35a determines a wind direction pattern in the same manner as the wind direction pattern for absent airflow control in step S108. The air conditioning control unit 35b performs airflow control on the corresponding indoor units 2a to 2d based on the wind direction pattern (S112). Thereby, for example, an air flow as shown in FIG. 11 is supplied to the building RA.

  Steps S113 to S114: When the setting made in Step S103 is the “no smoking” setting (Yes in S113), the determination unit 35a includes the air conditioning target zone that is not set to be non-smoking in the air conditioning target zone selected on the layout screen p1. Determine the wind direction pattern for smoking cessation so that conditioned air does not flow in. The air conditioning control unit 35b performs airflow control on the corresponding indoor units 2a to 2d based on the wind direction pattern (S114).

  Steps S115 to S116: When the setting made in Step S103 is the “smoking” setting (Yes in S115), the determination unit 35a determines that the air-conditioning target zone that is not the smoking setting is selected from the air-conditioning target zone selected on the layout screen p1. Determine the wind direction pattern for smoking so that conditioned air does not flow out. The air conditioning control unit 35b performs airflow control on the corresponding indoor units 2a to 2d based on the wind direction pattern (S116).

  Step S117: When the administrator or the like has changed the setting to be different from the current setting using the layout screen p1 and the setting screens p2 and p3 on the operation panel 32 (Yes in S117), the air conditioning control device 3 , The operation after step S105 is repeated.

  Step S118: The air conditioning control device 3 repeats the operation of step S117 until the power is turned off (No in S118). When the power is turned off (Yes in S118), the air conditioning control device 3 ends the series of operations.

  21 and 22, as an example, in the order of “swirl airflow mode” setting, “absence” setting, “apply airflow” setting, “do not apply airflow” setting, “no smoking” setting, “smoking” setting. The case where the setting is confirmed has been described. However, the order in which the settings are accepted is not limited to this and can be arbitrarily changed. For example, based on the priority of the operation corresponding to each button described in FIG. 13, “apply airflow” / “do not apply airflow” setting, “swirl airflow mode” setting, “absence” setting, “no smoking” / The setting may be confirmed in the order of “smoking” setting.

  Further, the priority order of the operation corresponding to each selected button is not limited to the order shown in FIG. For example, the priority order of the operation corresponding to each button is customized for each user according to the situation used by the user, or the so-called learning function in which the priority order changes according to the state actually used by the user. It may be changed as appropriate.
