Hereinafter, embodiments of the present invention will be described with reference to the drawings.
This air conditioning control system includes a plurality of opening and closing devices 10 that open and close an opening that is an indoor / outdoor boundary, and an air conditioning device 20 that air-conditions a space partitioned by the opening and closing device 10.
The opening / closing device 10 may be any device that partitions or opens a space by an opening / closing operation of an opening / closing body, such as a window, a door, a sliding door, or a shutter device. The opening / closing apparatus 10 includes an opening / closing state signal output means (not shown) for outputting the opening / closing state of the opening / closing body.

The open / close status signal output means detects, for example, an open / close body when fully closed by a contact or non-contact type sensor (for example, a proximity switch or a limit switch), and outputs the detection signal as an open / close status signal. And
This open / close status signal output means is wired to a control unit 22 of the air conditioner 20 described later. As another example, a mode in which the detection signal of the open / close state signal means is wirelessly output and the wireless signal is received by the control unit 22 can be employed.

  The air conditioner 20 is an air conditioner that performs air conditioning using a refrigeration cycle. The compressor 21 compresses and circulates refrigerant in the refrigeration cycle, the control unit 22 that controls the compressor 21, and the air conditioner 20. A display unit 23 for displaying the operating status of the vehicle and the switching status of the switchgear 10, an indoor heat exchanger (not shown), an outdoor heat exchanger (not shown), a blower (not shown), etc. Yes.

  In the illustrated example, a single air conditioner 20 is provided, but an embodiment having a plurality of air conditioners 20 is also possible.

  The compressor 21 includes a compression unit including a mechanism (for example, a piston and cylinder mechanism, a rotary mechanism, or a scroll mechanism) that compresses the refrigerant, and a motor that serves as a power source for driving the compression unit. The number of revolutions of the motor is controlled by an inverter power supply device provided in the control unit 22.

The control unit 22 includes a so-called microcomputer circuit including a CPU, a storage device, and the like, an inverter power supply device, and the like, and serves as a power saving control unit that sets the air conditioner 20 in a power saving state in accordance with an opening / closing status signal from the switching device 10. Function.
In addition, the control unit 22 uses the display unit 23 to display the opening and closing of the opening / closing device 10 by voice and / or visual display, means for displaying the opening / closing status of the opening / closing device 10, and other controls shown in the flowcharts described later. It functions as a means for performing an operation.

The display unit 23 is a well-known display device including a liquid crystal panel, a speaker, and the like, and displays the operation status of the air conditioner 20 and opens / closes by voice display and / or visual display according to a display signal from the control unit 22. The closing alert of the device 10 and the display of the opening / closing status of the opening / closing device 10 are performed.
The display unit 23 is separate from the other parts of the air conditioner 20 and is installed at an easily viewable location in the building.

Next, the control operation by the control unit 22 will be described in detail with reference to the flowchart shown in FIG.
First, the control unit 22 starts the operation of the air conditioner 20 in response to a signal from an operation unit (such as a controller) (not shown) (step 1). Specifically, power is supplied to the compressor 21 and a blower (not shown).

  Next, in step 2, the open state of each switchgear 10 is left unattended. More specifically, the control unit 22 displays the open / close status of each open / close device 10 on the display unit 23 in accordance with the open / close status signal output from the open / close status signal output means of the open / close device 10.

  Next, in step 3, it is determined from the opening / closing status signal whether or not all of the plurality of opening / closing devices 10 are fully closed. The process is repeated, and if it is determined that there is an opening / closing device 10 that is not fully closed, the process proceeds to the next step 4.

  In step 4, the air conditioner 20 is put into a power saving state. If it demonstrates in detail, the control part 22 will reduce the rotation speed of the compressor 21 by reducing the output of an inverter power supply device. Therefore, the air conditioner 20 as a whole is operated in a power saving state.

  In step 5, based on the open / close status signal, it is determined whether or not the open state of the switchgear 10 has continued for a predetermined time or more. If it is determined that the open state has continued for a predetermined time or longer, the process proceeds to step 6. If not, the process jumps to Step 7.

Here, whether or not the open state of the opening / closing device 10 has continued for a predetermined time or more is determined by determining whether the opening / closing device 10 of the plurality of opening / closing devices 10 is not fully closed. Whether or not the state has continued for a predetermined time or more may be determined based on the open / close status signal.
As another example, it is also possible to determine whether or not the open state of the switchgear 10 has continued for a predetermined time or more for each of the switchgears 10.

  In addition, the predetermined time in Step 5 may be set, for example, based on a time generally required for people to enter and exit at an entrance, a time for taking in laundry that has been dried out from a window, and the like.

  In step 6, the display unit 23 displays a sound for closing the opening / closing device 10 by voice and / or visual display. Specifically, for example, audio display and / or visual display such as “Please close window” is performed.

  In step 7, based on the open / close status signal, it is determined whether or not all of the plurality of open / close devices 10 are fully closed. If all the open / close devices 10 are fully closed, the process proceeds to the next step 8; Return the processing to 5.

In step 8, the power saving state of the air conditioner 20 is canceled. If it demonstrates in detail, the control part 22 will raise the rotation speed of the compressor 21 to the original state by raising the output of an inverter power supply device. Therefore, the air conditioner 20 returns to a normal operation state in which power is not saved.
Then, after step 8, the process by the control unit 22 is returned to step 3.

  In addition, when there is a command to turn off the air conditioner 20 by a user's operation, the air conditioner 20 can be turned off in any of the above steps.

Thus, according to the air conditioning control system of the present embodiment, when there is an opening / closing device 10 that is not fully closed, the air conditioning device 20 can be automatically put into a power saving state. Therefore, it is possible to prevent the power of the air conditioner 20 from being wasted.
Moreover, the resident or the like can recognize which opening / closing device 10 is in the open state by the display content of the display unit 23.
In addition, when there is an opening / closing device 10 that is open for a long time, the closing of the opening / closing device 10 can be automatically activated.

Next, another embodiment whose control example is shown in FIG. 3 will be described.
In this embodiment, the opening / closing device 10 is configured to automatically close the opening / closing body in response to a closing command (for example, an electric shutter device), and the closing command for the opening / closing device 10 and the start of operation of the air conditioner 20 are used. And are linked.

  Since the flowchart of FIG. 3 is obtained by changing Step 1 of the flowchart of FIG. 2 to Steps 1a, 1b, and 1c, only the changed portion will be described.

  First, in step 1a, the control unit 22 issues a closing command to the opening / closing device 10 in accordance with a signal from an operation unit (controller or the like) (not shown). Therefore, the opening / closing device 10 starts a closing operation in response to the closing command.

  Next, in step 1b, the operation of the air conditioner 20 is started.

Next, in step 1c, the process waits for the predetermined time t1 to elapse, and proceeds to step 2 after the predetermined time t1 elapses.
The predetermined time t1 is set to a time slightly longer than the time from when the opening / closing device 10 starts the closing operation until it fully closes.

  Step 2 and subsequent steps are the same as those in the embodiment described above.

  Thus, according to the other embodiment, the closing operation of the switchgear 10 and the start of operation of the air conditioner 20 can be linked. As a result, it can be prevented that only the air conditioner 20 is operated before the opening / closing device 10 is closed, and the air conditioning energy of the air conditioner 20 is wasted.

Next, another embodiment whose control example is shown in FIG. 4 will be described.
Also in this embodiment, the opening / closing device 10 is configured to be automatically closed upon receipt of a closing command (for example, an electric shutter device or an electric sliding door device).

  Since the flowchart of FIG. 4 is obtained by changing Step 4 of the flowchart of FIG. 2 to Steps 4a, 4b, 4c, 4d, and 4e, only the changed portion will be described.

  In step 4a, the air conditioner 20 is put into a power saving state in the same manner as in the embodiment described above.

In step 4b, the process waits for the predetermined time t2 to elapse, and proceeds to step 4c after the predetermined time t2 elapses.
The predetermined time t <b> 2 is appropriately set so as to secure time for people to enter and exit the space delimited by the air conditioner 20.

  In step 4c, based on the opening / closing status signal input from the opening / closing device 10, it is determined whether there is an opening / closing device 10 in an open state. If there is an opening / closing device 10 in an open state, the process proceeds to the next step 4d. Otherwise, return to step 3.

  In step 4d, a closing command is issued to the opening / closing device 10. Therefore, the opening / closing device 10 performs a closing operation. When there is an obstacle in the closing path of the opening / closing body and the opening / closing device 10 is stopped by the operation of the obstacle sensing device, the opening / closing device 10 is not closed again.

In step 4e, the process waits for the predetermined time t1 to elapse, and proceeds to step 5 after the predetermined time t1 elapses.
The predetermined time t1 is set to a time slightly longer than the time from when the opening / closing device 10 starts the closing operation until it fully closes.

  Step 5 and subsequent steps are the same as in the above-described embodiment.

  Thus, according to this embodiment, when the air conditioner 20 is operating in the power saving state and the open / close device 10 is open, the open / close device 10 can be automatically closed. As a result, it can prevent more effectively that the air-conditioning energy of the air conditioner 20 is wasted.

  In addition, according to the said embodiment, as the means for putting the air conditioner 20 into the power saving state, the output of the inverter power supply device is lowered to reduce the rotation speed of the compressor 21, but as another example, the air conditioner It is good also as a mode which turns off all 20 power supplies or a part of power supplies, a mode which operates an unloader device of a compressor, and performs unloading.

  Further, as another example, a mode in which the power saving amount of the air conditioner 20 is changed according to the number of the switching devices 10 that are not fully closed, that is, a mode in which the power saving amount of the air conditioning device 20 is increased as the number of the switching devices 10 that are not fully closed increases. It is also possible to do.

  Further, as another example, a mode in which the opening amount of the switching device 10 is detected and the power saving amount of the air conditioning device 20 is changed according to the opening amount, that is, the power saving amount of the air conditioning device 20 is larger as the opening amount of the switching device 10 is larger. It is also possible to adopt an embodiment in which

Further, when a usage mode in which the opening / closing device 10 is not connected to the air conditioner 20, that is, a usage mode in which the air conditioner 20 is used alone, is connected to the air conditioner 20 in the usage mode. The processing by the control unit 22 may be executed assuming that all the opening / closing devices 10 (open / close devices 10 that are not actually connected) are closed.
Specifically, with respect to the terminal connecting the switchgear 10 in the air conditioner 20, the electrical state of the terminal when the switchgear 10 is not connected and the terminal when the connected switchgear 10 is closed The open / close state signal of the open / close state signal output means may be set so that the electrical state of the open / close state signal is the same (for example, the terminal is open in any case).

  Further, in the other embodiment shown in FIG. 3, the air conditioner 20 is controlled according to the open / close status of the plurality of switchgears 10. Among them, for some of the opening / closing devices 10, the operation control of the air conditioner 20 according to the opening / closing status of the opening / closing device 10 may be canceled based on a manual operation or an automatic operation. (In this case, for example, the part of the opening / closing devices 10 may be regarded as a closed state and the air conditioner 20 may be controlled.) As a usage mode of this configuration, for example, rooms that have been subjected to similar air conditioning are used. It is useful to cancel the opening / closing device for opening / closing the communicating opening as described above when it is desired to keep the opening / closing device open.

  Further, in the other embodiment shown in the control example in FIG. 3, when the configuration having a plurality of opening / closing devices 10 in one room is used, the air conditioner 20 is operated according to the opening / closing states of all the opening / closing devices 10. You may make it control, and you may make it carry out operation control of the air conditioner 20 according to the opening / closing condition of some opening / closing apparatuses 10. FIG. According to the latter mode, for example, only a part of the opening / closing devices 10 that open and close the opening portion where the temperature difference is likely to occur before and after the opening portion, the closing operation is interlocked with the start of the operation of the air conditioner 20, and the other opening / closing devices. It can be used that 10 is not linked.
