  According to the air conditioning control system of the present invention, a plurality of airflows having different wind directions of horizontal components are generated by airflow control of a plurality of blowers, and a comfortable environment is provided to a resident by an airflow that is closer to natural wind. The resident can freely set the wind direction, and when setting the wind direction, it is easy to confirm which wind direction is set while feeling the changing air flow and recognizing the display and notification sound. be able to. Therefore, convenience and operability can be significantly improved as compared with the conventional case.

  Hereinafter, the best mode for carrying out an air conditioning control system according to the present invention will be described with reference to the drawings. In addition, this invention is not limited by this embodiment.

  FIG. 1 is a control block diagram showing an air conditioning control system according to the present invention, and FIG. 2 is a schematic plan view showing a room to which the air conditioning control system of the present invention is applied.

  The air conditioning control system of the present invention includes a plurality of blowers 4... 4 and a blower control means 5 for controlling the blown amount of these blowers. The blower control means 5 includes a control pattern setting means 6 for setting a control pattern for controlling the air flow rate of each blower in time series according to the number of wind directions of the horizontal component of the airflow sent from the blowers 4. The wind direction having the highest occurrence frequency among the horizontal component wind directions is set as the main wind direction, and is connected to the main wind direction setting means 7 for setting the main wind direction so that transmission and reception are possible.

  In the main wind direction setting means 7, for example, a communication means such as the controller 3 that can transmit a signal to the blower control means 5 is selected so that the resident can select the wind direction that the resident wants to feel the most air current and set the wind direction. Comes with. With such a system configuration, each of the fans 4... 4 generates a plurality of airflows having different horizontal component wind directions, and the airflow is controlled in time series so that the horizontal component wind direction changes over time. It is designed to generate an airflow close to the wind.

  In the room 1 to which the air conditioning control system is applied, for example, as shown in FIG. 2, three blowers 4 (a), 4 (b), and 4 (c) are installed in the vicinity of the ceiling of three wall surfaces. . The airflow generated by these blowers 4 is directed toward the resident 2.

  Specifically, the blower 4 (a) is an air flow in the front direction of the resident 2, the blower 4 (b) is an air flow in the back direction of the resident 2, and the blower 4 (c) is the right side direction of the resident 2. It is comprised so that the airflow to each may be produced | generated.

  Each of these blowers 4 is coupled to the blower control means 5 by a signal line and a power supply line (not shown), and the blower amount of each blower 4 is in accordance with a time-series control pattern stored in advance in the control pattern setting means 6. It is controlled. In addition, the resident 2 transmits a signal to the blower control means 5 using the controller 3 to select a wind direction to be operated or stopped, or to select a wind direction as a main wind direction among the three directions of air flow sent out by the blower 4. You can change the settings.

  The operation and action of the air conditioning control system having such a configuration will be described below. FIG. 3 shows each of the fans 4 (a) to 4 (4) when the setting of the wind direction as the main wind direction is changed among the three directions of air flow sent out by the three fans 4 (a) to 4 (c). It is explanatory drawing which shows the control pattern of the ventilation volume of c).

  As illustrated, in each of the fans 4 (a) to 4 (c), the amount of air sent out during operation can be controlled in four stages: “strong wind”, “medium wind”, “weak wind”, and “light wind”. It is said that. Then, until the elapsed time 0 to T4, the air blowers 4 (a) to 4 (c) are sent so that the air blowing frequency from the blower 4 (a) becomes the highest among the three wind directions with respect to the resident 2. An air volume control pattern is set and controlled.

  And in the elapsed time T4, the case where the resident 2 in the room 1 is replaced, for example, feels that the air blowing frequency from the blower 4 (b) is desired to be the highest, and the resident 2 tells the controller 3 The main wind direction setting means 7 provided is used to change and set the main wind direction to the blower 4 (b). Thereby, after elapsed time T4, the ventilation frequency from the air blower 4 (b) becomes the highest, exceeding the ventilation frequency from the air blower 4 (a) and the air blower 4 (c). At the same time, the control pattern setting means 6 newly sets and changes the control patterns of the fans 4 (a) to 4 (c), and controls the air flow rates of the fans 4 (a) to 4 (c) according to the control pattern. Will be.

  In this way, when the occupant 2 in the room 1 changes or when the occupant 2's sitting direction changes, the preferred wind direction can be changed according to the resident 2's request. It can be done.

  Further, the resident 2 changes the main wind direction with the controller 3 to the wind direction from the blower 4 (b) for a predetermined time from the time T4 to T5, the blower 4 (a) and the blower 4 (c) that do not send the main wind direction. ) Is set to “slight wind” which is the minimum air volume, and the air volume from the blower 4 (b) is set to “strong wind” which is the maximum air volume and is controlled instantaneously. Thereby, the resident 2 can easily confirm the change of the main wind direction while realizing which wind direction the airflow has become the main wind direction.

  Next, a description will be given of a case where the blower 4 that is the main wind direction is operated in such a manner that the blower 4 (a) → the blower 4 (b) → the blower 4 (c) is changed instantaneously.

  Each blower 4 is not completely stopped even when the main wind direction is not sent out. For example, as shown in FIG. 3, the blower 4 always blows air with a flow rate equal to or less than the maximum flow rate in the range of “light wind” to “medium wind”. Driving. That is, when such a continuous change operation is performed and the blower 4 that does not send out the main wind direction is newly set as the blower 4 that sends out the main wind direction, the blower 4 is stopped at the time of the change operation. Rather than sending a breeze. Therefore, the blower 4 can immediately shift the air volume in the main wind direction to the “strong wind” having the maximum air volume. Thereby, even if the resident 2 performs a continuous instantaneous change operation, the resident 2 can easily check the change setting of the blower 4 while feeling the airflow sent from the blower 4.

  In such a case, in the illustrated embodiment, the controller 3 is shown to distinguish the fans 4 (a) to 4 (c) by adding the configuration described below. It is possible to eliminate the need for the resident 2 to memorize the correspondence between each symbol of the blower and the blowers 4 (a) to 4 (c) installed in the room 1.

  In the present invention, the blower 4 is preferably provided with a display unit 41 that can display that the main wind direction has been selected. FIG. 4 is an explanatory diagram showing an operation example of the display unit 41 of each blower 4 when the main wind direction is changed in the air conditioning control system of the present invention.

  When the blower 4 (a) to 4 (c) having the display unit 41 is selected as a blower that sends out the main wind direction (elapsed time T4), the resident 2 can It shows that the blower 4 is set as the main wind direction. Further, in the blower 4 that has sent the main wind direction, the display unit 41 is turned off when the main wind direction is switched (elapsed time T4).

  With such a configuration, the resident 2 can confirm which blower 4 is set to the main wind direction while viewing the display unit 41, and the resident 2 can select from among a plurality of wind direction settings. It is possible to easily realize a comfortable and comfortable wind direction change without being confused about selection.

  The air blower 4 may be provided with a sound generation unit 42 that can notify that the main wind direction has been selected. FIG. 5 is an explanatory diagram showing an operation example of the sound generation unit 42 of each blower 4 when the main wind direction is changed in the air conditioning control system of the present invention.

  When the blower 4 (a) to 4 (c) having the sound generation unit 42 is selected as a blower that sends out the main wind direction (elapsed time T <b> 4), the sound generation unit 42 generates a notification sound such as “Bee”, for example. This indicates to the resident 2 that the blower 4 has been set as the main wind direction. Thereby, the resident 2 can confirm the setting while listening to the sound from the blower 4 (b) that is set as the main wind direction, and can easily and comfortably select from a plurality of wind direction settings. It can be changed in the wind direction.

  The method of indicating that the main wind direction is selected on the display unit 41 is not limited to lighting / extinguishing, and any display means may be used, such as some graphic display. The sound generation unit 42 may also indicate that the main wind direction has been selected by issuing some voice guidance. By providing such a display unit 41 or sound generation unit 42 in the blower 4, it is possible to reduce the burden of operation on the resident 2.

  As described above, in the air conditioning control system according to the present invention, the occupant 2 can change the airflow environment to the direction of the wind in the direction in which he / she wants to feel the airflow at any time, depending on the resident's preference, physical condition, etc. It is possible to provide an airflow environment that brings about a more comfortable wind direction change. At this time, when the setting of the main wind direction of the blower 4 is changed by the main wind direction setting means 7, the air flow from the changed main wind direction can be easily controlled to the maximum air volume, and the other delivery Since the airflow of the machine 4 is operated with the minimum airflow, it is possible to cope with an instantaneous change operation without causing a time lag.

  In addition, the resident 2 can confirm which wind direction the main wind direction has been set while actually feeling the airflow, or can confirm by the operation of the display unit 41 and the sound generation unit 42, and a plurality of wind direction settings You can easily change the wind direction to your liking without losing your choice.

  As described above, the air conditioning control system according to the present invention forms a more natural airflow environment in the room, and moreover, it is possible to form a more comfortable airflow environment according to the preference of the resident and the state of the body, It can be applied not only to residential air conditioning systems but also to air conditioning systems in offices and stores.
