JP-A-7-18946

By the way, in the opening/closing control device described above, the opening/closing portion such as an automatic door is operated to open/close, which causes a reduction in the air-conditioning effect of the air-conditioning equipment. Therefore, there is a demand for an opening/closing control device capable of suppressing the operating amount of the air conditioning equipment. Note that the opening/closing unit is not limited to an automatic door, and includes a window or the like that allows air to flow between the inside and the outside of the space at the opening.

SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and an object of the present invention is to provide an opening/closing control device capable of suppressing the operating amount of an air conditioner.

The opening/closing control device for solving the above problems includes a setting information acquisition unit for acquiring setting information related to the air conditioning of an air conditioning facility for air conditioning a space; an in-space information acquisition unit that acquires information; and an opening by an opening/closing unit that opens and closes an opening provided in the space when a difference between the value of the setting information and the value of the in-space information is greater than a predetermined value. and a limiting portion that limits the opening amount of the portion.

According to the above configuration, by limiting the amount of opening of the opening by the opening and closing part, the inflow and outflow of air in the opening is suppressed, the fluctuation of the environmental state in the space is suppressed, and the value of the setting information of the air conditioning equipment It is possible to shorten the time until the value of the spatial information reaches. Therefore, the operating amount of the air conditioner can be suppressed.

The opening/closing control device includes an outside-space information acquisition unit that acquires outside-space information that indicates an environmental state outside the space and that can be compared with the setting information. It is preferable that the opening amount by the opening/closing section is increased when the value is between the value of the information and the value of the information in the space.

According to the above configuration, the value of the information outside the space is closer to the value of the setting information than the value of the information inside the space. The value of the space information becomes more likely to approach the value of the setting information, and the time required for the value of the space information to reach the value of the setting information of the air conditioner can be shortened.

In the opening/closing control device, the limiting unit does not limit the amount of opening by the opening/closing unit for a predetermined period of time, and after the predetermined period of time elapses, the difference between the value of the setting information and the value of the information in the space increases. It is preferable to limit the amount of opening by the opening/closing section when the opening amount is larger than the predetermined value. According to the above configuration, since the amount of opening of the opening by the opening/closing unit is not limited as usual for the predetermined time, it is possible to suppress deterioration of convenience.

In the opening/closing control device, it is preferable that the limiting section limits the amount of opening by the opening/closing section when the difference is larger than the predetermined value and the air conditioning load of the air conditioner is large.

According to the above configuration, when the air conditioning load is large, that is, when the air conditioning equipment is greatly affected, the amount of opening of the opening by the opening and closing part is limited, so the impact on the air conditioning equipment is suppressed and the decrease in convenience is suppressed. can do.

In the opening/closing control device, it is preferable that the opening amount by the opening/closing portion is restricted by narrowing a detection range in which a sensor for opening the opening/closing portion detects a person or an object. According to the above configuration, when the detection range of the sensor for opening the opening/closing part is reduced, the detection by the sensor is reduced, so that the amount of opening of the opening by the opening/closing part can be limited.

In the opening/closing control device described above, it is preferable that the opening amount of the opening/closing portion is restricted by shortening the open state time of the opening/closing portion.
According to the above configuration, the opening amount of the opening by the opening/closing part can be limited because the opening/closing period of the opening/closing part is reduced.

In the opening/closing control device, it is preferable that the opening amount of the opening/closing portion is restricted by enabling the opening operation of the opening/closing portion only manually.
According to the above configuration, since the opening/closing portion does not open automatically, the open state time is reduced, and the amount of opening of the opening portion by the opening/closing portion can be restricted.

It is preferable that the opening/closing control device further includes a notification section that notifies that the opening amount is limited by the opening/closing section.
According to the above configuration, the notifying section notifies that the opening amount of the opening is limited by the opening/closing section, so that the user of the opening/closing section can understand the situation of the opening/closing section and respond accordingly.

(First embodiment)
A first embodiment of the opening/closing control device will be described below with reference to FIGS. 1 to 8. FIG. An opening/closing control device is provided in an automatic door that opens and closes an opening provided in a space included in a building.

As shown in FIG. 1, in a space 2 included in a building 1, an air conditioner 10 for air conditioning the space 2 is installed on the left side of the drawing. An opening 20 through which a person enters and exits the space 2 is provided on the right side of the drawing. The opening 20 is provided with an automatic door 21 as an opening/closing unit for opening and closing the opening 20 . The automatic door 21 opens and closes the opening 20 by moving the two doors 21A and 21B in the horizontal direction (vertical direction in the drawing). The door 21A on the upper side in the figure opens the opening 20 by moving to the upper side in the drawing, and closes the opening 20 by moving to the lower side in the drawing. The door 21B on the lower side of the drawing opens the opening 20 by moving to the lower side of the drawing, and closes the opening 20 by moving to the upper side of the drawing. The positions of the air conditioner 10 and the opening 20 (automatic door 21) can be arbitrarily set according to the building 1 and the space 2. FIG.

As shown in FIG. 2, the air conditioner 10 includes an air conditioner unit 11 that performs air conditioning, and a communication unit 12 that communicates setting information related to air conditioning of the air conditioner 10 with the outside. The air conditioning unit 11 adjusts the environment in the space 2 by adjusting the air to be blown in accordance with setting information such as set temperature and set humidity. The communication unit 12 transmits setting information such as operation information and setting temperature TP to the outside.

The automatic door 21 includes doors 21A and 21B, a driving device 22 that drives the doors 21A and 21B, and an opening/closing control device 30 that controls opening and closing of the doors 21A and 21B. The driving device 22 drives the doors 21A and 21B via a transmission mechanism (not shown).

The opening/closing control device 30 includes a determination unit 31 for determining whether or not to open/close the doors 21A and 21B, an opening/closing control unit 32 for instructing opening/closing of the doors 21A and 21B, and a driving device according to the instructions of the opening/closing control unit 32. 22, and a drive unit 33 for driving . The determination unit 31 and the opening/closing control unit 32 are electrically connected. In addition, the opening/closing control section 32 and the drive section 33 are electrically connected. The driving section 33 and the driving device 22 are electrically connected.

The drive unit 33 drives the drive device 22 to open when the opening/closing control unit 32 outputs an open command to the drive unit 33 . The drive unit 33 drives the drive device 22 to close when the open/close control unit 32 outputs a close command to the drive unit 33 . The driving unit 33 drives and controls the driving device 22 according to the command from the opening/closing control unit 32 so that the doors 21A and 21B are in each state such as a fully open state, a fully closed state, and a stopped state.

The opening/closing control device 30 includes a communication unit 34 that acquires a set temperature TP as setting information related to air conditioning of the air conditioner 10, and a space temperature measurement unit 35 that acquires a space temperature TR, which is the temperature indicating the environmental state in the space 2. and a notification unit 36 for notifying the operating state of the automatic door 21 . The determination unit 31 is electrically connected to the communication unit 34 , the space temperature measurement unit 35 and the notification unit 36 . The space temperature measurement unit 35 outputs the space temperature TR to the determination unit 31 . The communication unit 34 functions as a setting information acquisition unit, receives setting information by communicating with the communication unit 12 of the air conditioner 10 , and outputs operation information and setting information to the determination unit 31 . Note that the set temperature TP and the space internal temperature TR can be compared.

The opening/closing control device 30 limits the opening amount of the opening 20 by the automatic door 21 that opens and closes the opening 20 when the difference between the value of the setting information and the value of the space information is larger than a predetermined value. That is, the determination unit 31 determines whether or not the temperature difference TD between the set temperature TP of the air conditioner 10 and the internal air temperature TR is greater than the predetermined value VS. The determination unit 31 instructs the opening/closing control unit 32 to perform an opening/closing operation to limit the opening amount of the opening 20 by the automatic door 21 when the temperature difference TD between the set temperature TP and the space inside temperature TR is larger than a predetermined value VS. do.

Here, the "opening amount of the opening 20" is the opening area per unit time. The longer the length, the greater the opening amount.

Therefore, the wider the detection range of the detection sensor for opening the doors 21A and 21B, the earlier the timing at which the doors 21A and 21B are opened by the automatic door 21, and the longer the opening time of the opening 20, the greater the amount of opening. do. Conversely, the narrower the detection range, the later the timing at which the doors 21A and 21B are opened by the automatic door 21, and the shorter the opening time of the opening 20, the opening amount is reduced.

In addition, even after passing through the opening 20, the wider the detection range, the longer the time during which the doors 21A and 21B are kept open by the automatic door 21, and the longer the opening time of the opening 20 becomes. increases. Conversely, the narrower the detection range, the shorter the time during which the doors 21A and 21B are kept open by the automatic door 21, and the shorter the open time of the opening 20, so the amount of opening decreases.

Furthermore, by making the opening speed of the doors 21A and 21B higher than a predetermined value or closing speed lower than a predetermined value, the opening time of the opening 20 is lengthened, so the amount of opening is increased. Conversely, by making the opening speed lower than the predetermined value or the closing speed higher than the predetermined value, the opening time of the opening 20 is shortened, so the amount of opening is reduced.

Furthermore, when the opening 20 is forcibly maintained for a predetermined time regardless of the detection state of the detection range, increasing the predetermined time increases the amount of opening or shortening the predetermined time. The amount of opening can be decreased.

In addition, the setting value of the automatic door 21 related to the adjustment of the opening area of the opening 20 per unit time is not limited to the above.
The opening/closing control device 30 does not limit the opening amount of the opening 20 by the automatic door 21 during the predetermined time TH, and after the predetermined time TH elapses, the temperature difference TD between the set temperature TP and the space internal temperature TR reaches a predetermined value VS. Determines whether it is greater than

The opening/closing control unit 32 sets the operation mode of the automatic door 21 to the "normal mode" when the temperature difference TD between the set temperature TP and the internal air temperature TR is equal to or less than a predetermined value VS. That is, when determining that the temperature difference TD is equal to or less than the predetermined value VS, the determination unit 31 causes the switching control unit 32 to set the operation mode to the "normal mode". Then, the opening/closing control unit 32 controls opening/closing of the automatic door 21 in the “normal mode” according to the setting of the determination unit 31 . The "normal mode" is set as an operation mode in a normal state, and is an operation mode in which the opening amount of the opening 20 by the automatic door 21 is not restricted. Here, "the opening amount of the opening 20 is not limited" means a setting including the width of the detection range of the detection sensor for opening the doors 21A and 21B, which is preset in the automatic door 21. It means that various set values such as values, opening/closing speeds of the doors 21A and 21B, time in the open state, etc. are the same as those set in the normal state.

The opening/closing control unit 32 sets the operation mode of the automatic door 21 to the "closed mode" when the temperature difference TD between the set temperature TP and the space internal temperature TR is greater than a predetermined value VS. That is, when determining that the temperature difference TD is greater than the predetermined value VS, the determination unit 31 causes the switching control unit 32 to set the operation mode to the "closed mode". Then, the opening/closing control unit 32 controls opening/closing of the automatic door 21 in the “closed mode” according to the setting of the determination unit 31 . The “closed mode” is an operation mode in which the opening amount of the opening 20 by the automatic door 21 is restricted.

For example, the opening amount of the opening 20 is limited by narrowing the detection range of the detection sensor for opening the doors 21A and 21B closer to the doors 21A and 21B than normal, thereby adjusting the opening timing of the doors 21A and 21B relative to the position of the person. is slower than usual, and useless opening operations when passing in front of the doors 21A and 21B are suppressed. In addition, by narrowing the detection range of the detection sensor provided on the opposite side of the opening 20 from the detection sensor, closer to the doors 21A and 21B than usual, the doors 21A and 21B start to close relative to the position of the person. The opening amount of the opening 20 may be restricted by making the timing earlier than usual.

Further, the opening amount of the opening 20 is restricted by shortening the open state time of the doors 21A and 21B. For example, the speed at which the doors 21A and 21B open is made higher than normal, or the start timing of closing the doors 21A and 21B is made earlier than usual. Also, the time during which the doors 21A and 21B are fully open is shortened, and the closing speed of the doors 21A and 21B is made higher than usual. Further, the opening amount of the opening 20 is restricted by reducing the opening width of the opening 20 when the doors 21A and 21B are in the open state.

The determination unit 31 causes the open/close control unit 32 to end the "closed mode" of the operation mode of the automatic door 21 when the temperature TR in the space reaches the set temperature TP or the temperature difference TD becomes equal to or less than a predetermined value VS. , to set the operation mode of the automatic door 21 to the "normal mode".

The notification unit 36 notifies that the opening amount of the opening 20 is limited when the operation mode of the automatic door 21 is set to the "closed mode". The notification unit 36 may be a speaker that emits voice or sound, or a display device that displays the contents of notification. The installation positions of the speaker, display device, etc. of the notification unit 36 can be arbitrarily set to the blinds, the doors 21A, 21B, the door cases, the fixtures, etc. in which the opening/closing control device 30 is provided.

Next, the operation of the opening/closing control device 30 will be described with reference to FIGS. 3 and 4. FIG. In addition, in "Situation A" and "Situation B" in FIG. The operation mode of FIG. 3 is the operation mode determined by the flow chart of FIG.

First, the case of "situation A" shown in FIG. 3 will be described with reference to FIG.
As shown in FIG. 4, the opening/closing control device 30 determines whether the air conditioning is in operation (step S11). That is, the determination unit 31 determines that the air conditioning equipment 10 is in an operating state (step S11: YES) because there is operation information indicating that it is in operation obtained via the communication unit 34, and the air conditioning equipment 10 is acquired (step S12). That is, the determination unit 31 acquires “18° C.” as the set temperature TP via the communication unit 34 .

When there is no operation information obtained via the communication unit 12 indicating that the air conditioner 10 is operating, the determination unit 31 determines that the air conditioner 10 is not in operation (step S11: NO). Then, the operation mode of the automatic door 21 is set to "normal mode" (step S19), and the process proceeds to step S11. In step S19, the opening/closing control unit 32 opens the doors 21A and 21B when a person enters the detection range of the opening 20, and closes the doors 21A and 21B when the normal open keeping time elapses.

Subsequently, the opening/closing control device 30 acquires the space internal temperature TR (step S13). That is, the determination unit 31 acquires “17° C.” as the space temperature TR from the space temperature measurement unit 35 .

Subsequently, the switching control device 30 calculates the temperature difference TD (step S14). That is, the determination unit 31 calculates the temperature difference TD (18° C.−17° C.=1° C.) between the set temperature TP (18° C.) and the space internal temperature TR (17° C.).

Subsequently, the switching controller 30 determines whether or not the temperature difference TD is greater than the predetermined value VS (step S15). That is, determination unit 31 determines whether or not temperature difference TD is greater than predetermined value VS. When determining that the temperature difference TD (1° C.) is equal to or less than the predetermined value VS (5° C.) (step S15: NO), the determination unit 31 instructs the opening/closing control unit 32 to set the operation mode of the automatic door 21 to the "normal mode." ” (step S19), and the process proceeds to step S11.

Next, the case of "situation B" shown in FIG. 3 will be described with reference to FIG.
As shown in FIG. 4, the opening/closing control device 30 acquires the space temperature TR (step S13). That is, the determination unit 31 acquires “10° C.” from the space temperature measurement unit 35 as the space temperature TR.

Subsequently, the switching control device 30 calculates the temperature difference TD (step S14). That is, the determination unit 31 calculates the temperature difference TD (18° C.-10° C.=8° C.) between the set temperature TP (18° C.) and the space inside temperature TR (10° C.).

Subsequently, the switching controller 30 determines whether or not the temperature difference TD is greater than the predetermined value VS (step S15). That is, when the determination unit 31 determines that the temperature difference TD (8° C.) is greater than the predetermined value VS (5° C.) (step S15: YES), the opening/closing control unit 32 sets the operation mode of the automatic door 21 to the “closed mode. ” (step S16). In step S<b>16 , the opening/closing control unit 32 limits the amount of opening of the opening 20 by performing control such that the time during which the doors 21</b>A and 21</b>B are open is shortened.

Subsequently, the opening/closing control device 30 notifies the "closed mode" (step S17). That is, the notification unit 36 notifies that the opening amount of the opening 20 is restricted by the automatic door 21 .

Subsequently, the opening/closing control device 30 determines whether or not a predetermined time has passed (step S18). That is, if the time elapsed since the operation mode of the automatic door 21 changed from the "normal mode" to the "closed mode" is less than the predetermined time (10 minutes), the determination unit 31 determines that the predetermined time (10 minutes) has not elapsed (step S18: NO), and waits until the predetermined time (10 minutes) has elapsed.

On the other hand, if the time elapsed since the operation mode of the automatic door 21 changed from the "normal mode" to the "closed mode" is equal to or longer than the predetermined time (10 minutes), the determination unit 31 determines that the predetermined time (10 minutes) has passed (step S18: YES), and the process proceeds to step S11.

Next, the effects of this embodiment will be described.
(1) By limiting the opening amount of the opening 20 by the automatic door 21, the inflow and outflow of air in the opening 20 is suppressed, the fluctuation of the environmental state in the space 2 is suppressed, and the setting information of the air conditioner 10 It is possible to shorten the time until the value of the spatial information reaches the value. Therefore, the operating amount of the air conditioner 10 can be suppressed.

(2) Since the opening amount of the opening 20 by the automatic door 21 is not limited as usual during the predetermined time TH, it is possible to suppress a decrease in convenience.
(3) If the detection range of the detection sensor for opening the automatic door 21 becomes narrower, the amount of detection by the sensor decreases, so the opening amount of the opening 20 by the automatic door 21 can be limited.

(4) Since the time during which the automatic door 21 is open is reduced, the opening amount of the opening 20 by the automatic door 21 can be limited.
(5) Since the automatic door 21 does not open automatically, the time of the open state is reduced, and the opening amount of the opening 20 by the automatic door 21 can be restricted.

(6) Since the notification unit 36 notifies that the opening amount of the opening 20 is restricted by the automatic door 21, the user of the opening 20 can understand the situation of the automatic door 21 and respond accordingly. .

That is, when the determination unit 31 determines that the temperature difference TD (8° C.) is greater than the predetermined value VS (5° C.) (step S15: YES), the process proceeds to step S20.

Subsequently, the switching control device 30 determines whether or not the air conditioning load is large (step S20). That is, when the determination unit 31 determines that the air-conditioning air volume is "weak" and thus the air-conditioning load is small (step S20: NO), the opening/closing control unit 32 sets the operation mode of the automatic door 21 to the "normal mode" (step S19), and the process proceeds to step S11.

Next, the case of "situation E" shown in FIG. 5 will be described with reference to FIG.

Then, the opening/closing control section 32 controls opening and closing of the automatic door 21 in the “manual mode” according to the setting of the judgment section 31 . The "manual mode" is an operation mode in which the amount of opening of the opening 20 is limited by manually operating the doors 21A and 21B. For example, both the opening operation and the closing operation of the automatic door 21 may be manually enabled, or only the opening operation of the automatic door 21 may be manually enabled. The notification unit 36 notifies that the automatic door 21 is operated manually when the operation mode of the automatic door 21 is set to the "manual mode".
