  In FIG. 1, the whole block diagram of the air-conditioning control system 1 which concerns on embodiment of this invention is shown.

<Configuration of air conditioning control system>
As shown in FIG. 1, the air conditioning control system 1 includes an air conditioning control device 10, an air conditioner including an outdoor unit 20 and an indoor unit 30 that can communicate with the air conditioning control device 10 via a communication line, and the indoor unit 30. The remote controller 40 which transmits the command signal from a user, and the electric power demand control apparatus 50 are provided.

  The air conditioning control device 10 performs air conditioning control including airflow control in the air conditioning target space SP as will be described later. A plurality of indoor units 30 are arranged on the ceiling of the air conditioning target space SP. Each indoor unit 30 has outlets 30a at a plurality of locations (four locations in the illustrated example). The remote controller 40 transmits a command signal to each indoor unit 30 by the user's operation in the air conditioning target space SP. The electric demand control device 50 manages and controls the electric power demand of air conditioning equipment and other equipment.

<Configuration of air conditioning control device>
FIG. 2 schematically shows the configuration of the air conditioning control device 10. The air conditioning control device 10 includes a communication unit 11 for transmitting and receiving information, a blown air flow setting unit 12, a blown air flow changing unit 13, a thermo switching unit 14, an indoor unit operation switching unit 15, and a mode switching unit 16. And a setting pattern storage unit 17. The blown air flow setting unit 12, the blown air flow changing unit 13, the thermo switching unit 14, the indoor unit operation switching unit 15, and the mode switching unit 16 are arranged in a control unit of the air conditioning control device 10 including a CPU or the like. . The setting pattern storage unit 17 is arranged in an internal memory such as a RAM or a ROM or an external memory such as a hard disk.

  The communication unit 11 transmits and receives data and information necessary for air conditioning control to and from a management device (not shown) such as an air conditioner or a server. Moreover, the request | requirement command of the user who exists in air-conditioning object space SP is received via the remote controller 40, and it transmits to the said control part.

  The blown air flow setting unit 12 sets the blown air flow of each indoor unit 30. The setting of the blown airflow is, for example, the setting of the direction of the blown airflow, the air volume and the air temperature of the blown airflow. Details of these settings will be described later.

  The setting of the blowout airflow is performed for each outlet 30a of the indoor unit 30, and a setting pattern for forming an overall airflow in the air conditioning target space SP is stored in the setting pattern storage unit 17. A plurality of setting patterns are stored. The setting input of the blown airflow may be performed by the air conditioning manager or the user via the display unit 19 from the input unit 18 of the air conditioning control device 10. Alternatively, a user may access a server of a management company remotely via a mobile phone or a terminal, and input via an input screen provided from the server.

  The blowing airflow changing unit 13 switches and changes a plurality of setting patterns set by the blowing airflow setting unit 12. This switching may be performed automatically every predetermined time, or may be switched in accordance with a request command from the user. For example, if the direction of the blown airflow is automatically switched every predetermined time, the user is prevented from getting used to the airflow and comfort is improved.

  The thermo switching unit 14 switches between the thermo on and the thermo off for each indoor unit 30. This switching may be performed automatically every predetermined time, or may be performed in association with the operation state of the other indoor unit 30. Moreover, you may switch according to the request | requirement instruction | command from a user. By this switching, cold air or warm air is sometimes given, preventing the user from getting used to the temperature and improving comfort. In addition, as a setting pattern, only some of the indoor units 30 are always thermo-ON during cooling, thereby preventing a decrease in the dehumidifying capacity that occurs when the thermo-off and the thermo-on are repeated in a short period of time. It is possible to prevent overcooling due to thermo-ON of 30 simultaneously. For example, only the indoor unit 30 positioned on the diagonal line of the air conditioning target space SP may be always thermo-ON and stirred by a swirling airflow so that the dehumidifying effect is spread over the entire air conditioning target space SP.

  The indoor unit operation switching unit 15 performs switching between the operation for each indoor unit 30 and the operation stop. This switching may be performed automatically every predetermined time, or may be performed in association with the operation state of the other indoor unit 30. Moreover, you may switch according to the request | requirement instruction | command from a user. By performing this switching, the indoor units for the excess capacity are stopped and the power consumption is reduced. For example, every other indoor unit 30 aligned with the ceiling of the air conditioning target space SP is stopped. Thereby, the fan power etc. in the indoor unit 30 can be reduced. Moreover, even if the operation of some of the indoor units 30 is stopped, comfort is ensured by the swirling airflow.

  The mode switching unit 16 switches between a swirl airflow mode that forms a swirl airflow and a normal airflow mode that does not form a swirl airflow.

  The setting pattern storage unit 17 stores a plurality of setting patterns of the blown airflow of the entire air conditioning target space SP. As the setting pattern, for example, a pattern such as a clockwise airflow, a counterclockwise airflow, and a swing is set as the setting of the direction of the blown airflow.

<Setting of airflow>
As described above, the setting of the blown airflow includes the setting of the angle of the blown airflow, the air volume and the air temperature of the blown airflow.

  For example, the direction of the blown airflow is set by changing the angle of a plurality of flaps (not shown) provided inside the blowout port 30a. The direction of the blown airflow can be set for each blowout port 30a of each indoor unit, and is set in association with the setting of the direction of the blown airflow for other indoor units. Specifically, as shown in FIG. 3, when the direction of the blown airflow of the blower outlet 30 a-1 of the indoor unit 30 </ b> A is set, the blower outlet 30 a of the adjacent indoor unit 30 </ b> B according to the same direction as the blown airflow. The direction of the -1 blowing airflow is set. Next, the airflow of the air outlet 30a-3 of the indoor unit 30C is turned so that the airflow turns along the wall of the air conditioning target space SP with respect to the direction of the airflow of the air outlet 30a-2 of the indoor unit 30B. Direction is set. Similarly, the direction of the air flow from the air outlet 30a-4 of the indoor unit 30D, the air outlet 30a-5 of the indoor unit 30E, and the air outlet 30a-6 of the indoor unit 30F is set.

  The air volume of the blown airflow is adjusted, for example, by providing a known air volume adjusting mechanism that is provided inside the indoor unit 30 and expands / reduces the opening area of the blowout flow path. The blown airflow is set by setting the air volume adjusting mechanism. The air temperature of the blown airflow is set by the set temperature. The air temperature of the blown airflow is also set by changing the evaporation target temperature of the refrigerant. When the air temperature is set to a setting pattern in which the air temperature is first lowered and raised repeatedly during cooling, and is first raised and lowered repeatedly during heating, more comfort can be obtained.

<Processing operation of air conditioning control device>
FIG. 4 is a flowchart showing the flow of processing by the air conditioning control device 1 of the present embodiment.

  First, the operation of the air conditioner is started (step S101), and the blowing airflow is set or the stored setting pattern is read according to a request command from the user (step S102).

  Next, the indoor unit 30 is operated under airflow control along the set pattern (step S103). When the predetermined time has elapsed (step S104), the setting pattern is changed by reading a new setting or setting pattern (step S105). If there is an operation stop command (step S106), the operation is stopped (step S107), and the process ends.

<Characteristics of the air conditioning control system according to the embodiment>
(1)
In the air conditioning control system 1 according to the above embodiment, the blown air flow setting unit 12 of the air conditioning control device 10 sets the setting of the blown air flow from the blower outlet 30a of one indoor unit 30 to the setting of the blown air flow of the other indoor units 30. By performing in association with each other, it is possible to form an entire airflow such as a swirling airflow in the entire air-conditioning target space SP, and the blowing airflow changing unit 13 can switch the setting pattern that forms the entire airflow every predetermined time. it can. Therefore, uncomfortable feeling due to monotonous airflow, temperature unevenness and the like can be eliminated in the entire air-conditioning target space where a plurality of indoor units are arranged, and comfortable air conditioning can be realized.

(2)
In the air conditioning control system 1 according to the above embodiment, since the thermo switching unit 14 of the air conditioning control device 10 switches between the thermo-on and the thermo-off for each indoor unit 30, both the cooling of the entire air-conditioning target space SP and the reduction of the dehumidifying capacity are both performed. Preventing and combining with the formation of the entire air flow can more effectively eliminate discomfort due to temperature unevenness.

(3)
In the air conditioning control system 1 according to the above-described embodiment, the indoor unit operation switching unit 15 of the air conditioning control device 10 stops the indoor units for excessive capacity in order to perform switching between operation and stoppage for each indoor unit 30. Thus, the power consumption can be reduced, and by combining with the formation of the entire airflow, the discomfort due to temperature unevenness can be more effectively eliminated.

(4)
In the air conditioning control system 1 according to the above-described embodiment, the mode switching unit 16 of the air conditioning control device 10 switches between the swirling airflow mode that forms the swirling airflow as the entire airflow and the normal airflow mode that does not form the swirling airflow, and changes the blown airflow. Since the unit 13 switches the setting pattern of the blown airflow according to the mode switching command from the mode switching unit 16, the air conditioning control according to the situation in the air conditioning target space SP is possible, and various air conditioning modes can be realized.

<Modification>
(A)
When the air-conditioning control device 10 receives a command from the demand control device 50, for example, when the demand exceeds a predetermined value, the time during which the air temperature of some of the indoor units 30 is increased or decreased is shortened. Alternatively, control such as stopping the operation of some of the indoor units 30 may be performed. Thereby, the demand of demand control can be met, and the unpleasant feeling due to temperature unevenness can be more effectively eliminated by combining with the formation of the entire airflow.

(B)
When there is a request command for changing the set temperature or the like from the user via the remote controller 40 or the like, it may be possible to determine which indoor unit 30 to select in consideration of the position of the user. In this case, the position information of the user grasps the relative position of the user with respect to each indoor unit 30, and may be set corresponding to the ID information of the remote controller 40 or the like, or fixed. You may recognize by reading the one-dimensional barcode and the two-dimensional barcode containing the specific positional information stuck on the desk or the chair. Alternatively, it may be performed via a means for inputting the user's position information (such as accessing the management apparatus and inputting it via an input screen). From the position information of the user, the indoor unit 30 immediately before or immediately after the position of the user is selected along the direction of the blowing airflow. Thereby, in addition to the formation of the entire airflow, it is possible to meet the demand for local air conditioning.

(C)
When there is an absent area where there is no user in the air-conditioning target space SP, the air flow in that direction may not be emitted. In this case, known detection means (infrared sensor or the like) may be provided to detect the presence or absence of the user in the air-conditioning target space SP, or the operation may be stopped by the user via the remote controller 40 or the like. The absence area may be specified upon receipt. Thereby, power consumption can be reduced by stopping the indoor unit for excessive capacity, and uncomfortable feeling due to temperature unevenness can be more effectively eliminated by combining with the formation of the entire airflow.
