BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, ventilation systems according to embodiments of the present invention will be described in detail with reference to the drawings. The embodiments shown below are examples of embodiments of the present invention, and the present invention should not be construed as being limited to these embodiments. In addition, in the drawings referred to in this embodiment, the same parts or parts having similar functions are denoted by the same reference numerals or similar reference numerals, and repeated description thereof will be omitted. Also, the dimensional ratios in the drawings may differ from the actual ratios for convenience of explanation, and some configurations may be omitted from the drawings.

FIG. 1 is a block diagram showing a ventilation system 1 according to this embodiment. As shown in FIG. 1, the ventilation system 1 includes a ventilation unit 11, an opening amount acquiring unit 12, a target value acquiring unit 17, an ventilation amount changing unit 18, and an ventilation amount control unit 13 which is an example of a control unit. Prepare.

The ventilation part 11 ventilates between the closed space partitioned by the door and the outside of the closed section. The vent 11 may be, for example, a door 11a as shown in FIG. 2A or a ventilation fan 11c as shown in FIG. 2B.

The opening amount acquisition unit 12 obtains the opening amount (output) of the door 11a by communication from the automatic door controller 11b (automatic door control unit) that opens and closes the door 11a as an input used to control the ventilation amount (output) of the ventilation unit 11. hereinafter also referred to as door opening amount). Note that the automatic door controller 11 b may be configured as part of the ventilation system 1 . Further, the opening amount acquiring unit 12 acquires the door opening amount from the degree of opening of the door 11a by a sensor such as a contact or an encoder (not shown) provided on the door 11a without communication with the automatic door controller 11b. Also good. Furthermore, the opening amount acquisition unit 12 may be configured as part of a program or hardware in the automatic door controller 11b.

The target value acquiring unit 17 acquires a target value of ventilation between the closed space partitioned by the door 11a and the outside of the closed section (hereinafter also referred to as a target ventilation volume) from a host system (not shown) through communication. In this case, the host system may, for example, acquire the door opening amount by communication from the automatic door controller 11b, and determine the ventilation amount target value to be smaller as the acquired door opening amount increases. It should be noted that the target value acquisition unit 17 may acquire the ventilation amount target value from switches such as a rotary switch without using communication. Furthermore, the target value acquisition unit 17 may be configured as part of the program or hardware in the automatic door controller 11b.

The ventilation amount changing unit 18 increases or decreases the ventilation amount between the closed space partitioned by the door 11a and the outside of the closed section by controlling the opening/closing speed, opening time, closing position, etc. of the door 11a. . In the example of FIG. 1, the ventilation amount changer 18 increases the ventilation amount. The ventilation amount changer 18 may be configured as part of the program or hardware in the automatic door controller 11b.

When the ventilation amount control unit 13 determines that the ventilation amount calculated based on the door opening amount acquired by the opening amount acquiring unit 12 is insufficient compared to the ventilation amount target value acquired by the target value acquiring unit 17. First, as shown in FIG. 1, the ventilation amount changer 18 is controlled so as to increase the ventilation amount (that is, the output) of ventilation by the ventilation section 11 . The ventilation amount control unit 13 may be configured, for example, as part of a program or hardware in the controller b of the automatic door. In addition, when the ventilation amount control unit 13 determines that the ventilation amount calculated based on the door opening amount is excessive compared to the ventilation amount target value, the ventilation amount of ventilation by the ventilation unit 11 (that is, the output) The ventilation amount changing unit 18 may be controlled so as to decrease the . Furthermore, when the ventilation amount control unit 13 determines that the ventilation amount target value and the ventilation amount calculated based on the door opening amount substantially match, the ventilation amount of ventilation by the ventilation unit 11 (that is, the output ) may be controlled to maintain the ventilation amount changer 18 .

Here, the door 11a may be either automatic or manual. Further, the door 11a may be any of a sliding door, hinged door, glide door, folding door and revolving door. Also, the door may be singular, as illustrated in FIGS. 2A and 2B, or may be plural.

The door opening amount may be the number of times the door 11a is opened and closed per unit time, or the opening time of the door 11a per unit time. Further, the door opening amount may be corrected based on the opening width, height, pressure difference between inside and outside, temperature difference, wind direction, and wind speed. Further, when there are a plurality of doors 11a, the door opening amount may be the sum total, the median value, the average value, or the maximum/minimum value of the opening amounts of the doors 11a. Further, the opening amount when there are a plurality of doors 11a may be an opening amount determined by weighting according to the installation position of each door 11a. Further, the door opening amount may be calculated by integrating the position of the door 11a and the time spent at that position. Further, the height of the door 11a may be taken into consideration when calculating the door opening amount.

The closed space and the outside of the closed space are spaces that communicate with each other through the opening of the door 11a when the door 11a is opened. The closed space and the outside of the closed space may be, for example, a conference room, a waiting room, an office, a store, or inside or outside a tenant. Also, outside the enclosed space may be either indoors (ie, another enclosed space) or outdoors.

The ventilation rate is the amount of fluid that passes between the closed space and the outside of the closed space per unit time. A fluid is, for example, a gas such as air. Fluids may include liquids such as water, and may include solids such as dust, pollen and yellow sand.

In controlling the ventilation amount based on the ventilation amount target value and the door opening amount, the ventilation amount control unit 13 changes the ventilation amount when the ventilation amount calculated based on the door opening amount is larger than the ventilation amount target value. The ventilation amount is decreased by the unit 18, and when the ventilation amount calculated based on the door opening amount is smaller than the ventilation amount target value, the ventilation amount changing unit 18 may be used to increase the ventilation amount.

Further, when the ventilation amount calculated based on the amount of door opening is equal to or greater than a value preset as the ventilation amount target value, the ventilation amount control section 13 sets the ventilation amount to be changed by the ventilation amount changing section 18 to zero. When the ventilation amount calculated based on the amount of door opening is less than the value preset as the ventilation amount target value, the ventilation amount changing unit 18 is controlled so as to achieve a predetermined ventilation amount. may In this case, unlike the above example, the target value of ventilation is not dynamically changed, and the target value of ventilation is fixed and preset, so the target value acquisition unit 17 is not required.

The ventilation amount control unit 13 controls the pressure difference between the inside and outside of the closed space, the temperature difference from the appropriate temperature, the height and opening width of the door, the environment outside the closed space (for example, wind direction, wind speed, dust, chemical substances, pollen, PM2 .5, yellow dust, etc.), the ventilation amount to be increased or decreased by the ventilation amount changing unit 18 may be corrected.

In the process of increasing the ventilation amount, the ventilation amount control unit 13 may increase the ventilation amount in multiple stages, steplessly, or exponentially. In addition, the ventilation amount control unit 13 may reduce the ventilation amount in a multi-stage, stepless, or exponential manner during the process of decreasing the ventilation amount. Note that these can also be performed by the ventilation amount changing unit 18 .

The increase in airflow may be by increasing the number of rotations of the ventilation fan 11c from normal or by increasing the pitch of the ventilation fan 11c (to increase the ventilation at the same number of rotations). In addition, the increase in the amount of airflow can be achieved by providing a gap on the edge side of the door 11a when the door 11a whose opening amount is being monitored or a door 11a different from the door 11a is closed, and increasing the width of the opening when the door is fully opened. the open state holding time (hereinafter also referred to as an open timer) longer than normal, the opening speed of the door 11a faster than normal, or the closing speed of the door 11a faster than normal It can be slow. Also, the increase in ventilation may be an increase in the gap width of the window.

Decreasing the ventilation amount may be reducing the number of rotations of the ventilation fan 11c from the normal time or reducing the pitch of the ventilation fan 11c from the normal time (reducing the ventilation amount with the same number of rotations). In addition, the decrease in the ventilation amount is achieved by narrowing the gap provided in the door 11a when the door 11a whose opening amount is being monitored or a door 11a different from the door 11a is closed (if the gap is provided), The width of the opening when fully open is narrower than normal, the holding time of the open state is shorter than normal, the opening speed of the door 11a is slower than normal, or the closing speed of the door 11a is slower than normal. It can be faster.

As shown in FIG. 3, first, the target value acquisition unit 17 acquires the target value of ventilation (step S1). Next, the opening amount acquisition unit 12 acquires the door opening amount (step S2).

After the door opening amount is acquired, the ventilation amount control unit 13 calculates the current ventilation amount based on the acquired door opening amount (step S3). Next, the ventilation amount control unit 13 compares the acquired target ventilation amount with the calculated ventilation amount (step S4). When it is determined that it is (step S4: ventilation amount<ventilation amount target value), it is decided to increase the ventilation amount by the ventilation amount changing unit 18 (step S5). On the other hand, when the ventilation amount control unit 13 determines that the calculated ventilation amount is excessive compared to the ventilation amount target value (step S4: ventilation amount > ventilation amount target value), the ventilation amount changing unit 18 decreases the ventilation amount. may be determined (step S6). Furthermore, when the ventilation amount control unit 13 determines that the calculated ventilation amount substantially matches the target value (step S4: ventilation amount = ventilation amount target value), the ventilation amount is maintained by the ventilation amount changing unit 18. (step S7) (the same applies to the following modified examples).

After determining the mode of increasing, decreasing, or maintaining the ventilation volume, the ventilation volume control section 13 causes the ventilation volume changing section 18 to increase, decrease, or maintain the ventilation volume of the ventilation section 11 according to the determined mode. (Step S8).

According to this embodiment, it is possible to increase the ventilation amount by the ventilation amount changer 18 based on the ventilation amount target value and the door opening amount, so that ventilation can be performed in consideration of the usage situation of the door. .

(First modification)
Next, a first modification will be described in which the door opening amount is the number of times the door opens and closes per unit time.

FIG. 4 is a flow chart showing an operation example of the ventilation system 1 according to the first modified example of the present embodiment. The flow chart of FIG. 4 is repeated as necessary.

As shown in FIG. 4, after the target value acquisition unit 17 acquires the ventilation amount target value (step S1), the opening amount acquiring unit 12 acquires the number of times the door is opened and closed per unit time as the door opening amount ( step S21).

After the number of times the door has been opened and closed has been acquired, the ventilation amount control unit 13 calculates the current amount of ventilation based on the acquired number of times the door has been opened and closed (step S3). Thereafter, steps S4 to S8 are executed in the same manner as in the flowchart of FIG.

According to the first modification, in addition to the effects of the configuration shown in FIG. 1, by monitoring the number of times the door is opened and closed per unit time as the door opening amount, the door opening amount can be easily monitored. can be done.

(Second modification)
Next, a second modification in which the door opening amount is the door opening time per unit time will be described.

FIG. 5 is a flow chart showing an operation example of the ventilation system 1 according to the second modified example of this embodiment. The flow chart of FIG. 5 is repeated as necessary.

As shown in FIG. 5, after the target value acquisition unit 17 acquires the ventilation amount target value (step S1), the opening amount acquisition unit 12 acquires the door opening time per unit time as the door opening amount ( step S22).

After the door opening time is obtained, the ventilation amount control unit 13 calculates the current ventilation amount based on the obtained door opening time (step S3). Thereafter, steps S4 to S8 are executed in the same manner as in the flowchart of FIG.

According to the second modification, in addition to the effects of the configuration of FIG. 1, the accuracy of the door opening amount can be improved by monitoring the door opening/closing time per unit time as the door opening amount. can.

(Third modification)
Next, a third modified example for correcting the door opening amount will be described. FIG. 6 is a block diagram showing a ventilation system 1 according to a third modified example of this embodiment.

As shown in FIG. 6, the ventilation system 1 according to the third modification further includes an opening amount correction information acquisition section 14 in addition to the configuration of FIG.

The opening amount correction information acquisition unit 14 acquires opening amount correction information for correcting the door opening amount acquired by the opening amount acquisition unit 12 .

The opening amount correction information is, for example, at least one of the door opening width, the door height, the pressure difference between inside and outside the closed space, the temperature difference between inside and outside the closed space, the wind direction outside the closed space, and the wind speed outside the closed space. is.

The opening amount correction information acquisition unit 14 is composed of, for example, at least one of a storage unit of an automatic door controller, a pressure sensor, a temperature sensor, and a wind sensor. At least part of the opening amount correction information acquisition unit 14 may be configured by software.

The door opening amount acquired by the opening amount acquisition unit 12 is corrected based on the opening amount correction information acquired by the opening amount acquisition unit 12 . That is, the door opening amount is determined by at least one of the width of the door opening, the height of the door, the air pressure difference between inside and outside the closed space, the temperature difference between inside and outside the closed space, the wind direction outside the closed space, and the wind speed outside the closed space. corrected based on

For example, when it is desired to suppress ventilation due to a temperature difference such that the outside of the closed space is hotter than the inside of the closed space, the ventilation amount control unit 13 is made to determine that the amount of door opening is large, and ventilation is performed. The door opening amount may be corrected upward to reduce the amount. On the other hand, when it is desired to promote ventilation due to a temperature difference such that the outside of the closed space is lower in temperature than the inside of the closed space, the ventilation amount control unit 13 is made to determine that the amount of door opening is small, and ventilation is performed. The amount of opening may be downwardly corrected to increase the amount.

In the example of FIG. 6, the ventilation amount control unit 13 corrects the door opening amount input from the opening amount acquisition unit 12 using the opening amount correction information input from the opening amount correction information acquisition unit 14. there is Correction of the door opening amount may be performed by the opening amount acquisition unit 12 by acquiring the opening amount correction information from the opening amount correction information acquisition unit 14 .

The ventilation amount control unit 13 determines that the ventilation amount calculated based on the door opening amount corrected based on the opening amount correction information is insufficient compared to the ventilation amount target value acquired by the target value acquisition unit 17. At times, as shown in FIG. 1, the ventilation amount changing unit 18 is controlled so as to increase the ventilation amount of the ventilation unit 11 . Incidentally, when the ventilation amount control unit 13 determines that the ventilation amount calculated based on the corrected door opening amount is excessive compared to the ventilation amount target value, the ventilation amount of the ventilation unit 11 is reduced. The ventilation amount changing unit 18 may be controlled as follows. Further, the ventilation amount control unit 13 maintains the ventilation amount of the ventilation unit 11 when it is determined that the ventilation amount target value and the ventilation amount calculated based on the corrected door opening amount substantially match. The ventilation amount changing unit 18 may be controlled so as to allow

Next, an operation example of the ventilation system 1 according to the third modification will be described. FIG. 7 is a flowchart showing an operation example of the ventilation system 1 according to the third modified example of this embodiment. The flow chart of FIG. 7 is repeated as necessary.

As shown in FIG. 7, the opening amount obtaining unit 12 obtains the door opening amount (step S2) after obtaining the ventilation amount target value by the target value obtaining unit 17 (step S1).

Further, the opening amount acquisition unit 12 acquires opening amount correction information for acquiring the door opening amount (step S9). Acquisition of the opening amount correction information may be switched before and after acquisition of the door opening amount, or acquisition of the door opening amount may be performed at the same time.

After the opening amount correction information is obtained, the ventilation amount control unit 13 corrects the door opening amount obtained by the opening amount obtaining unit 12 based on the obtained opening amount correction information (step S10).

After the door opening amount is corrected, the ventilation amount control unit 13 calculates the current ventilation amount based on the corrected door opening amount (step S3). Thereafter, steps S4 to S8 are executed in the same manner as in the flowchart of FIG.

According to the third modification, in addition to the effects of the configuration shown in FIG. 1, by further correcting the door opening amount, it is possible to more appropriately increase the ventilation amount based on the door opening amount. can.

(Fourth modification)
Next, a fourth modification will be described in which the door opening amount is obtained based on the weighting of the opening amounts of a plurality of doors. FIG. 8 is a flow chart showing an operation example of the ventilation system 1 according to the fourth modified example of this embodiment. The flowchart of FIG. 8 is repeated as necessary.

In the ventilation system 1 according to the fourth modification, the opening amount acquisition unit 12 acquires the door opening amount according to the flowchart of FIG.

Specifically, as shown in FIG. 8, first, the opening amount acquisition unit 12 acquires the door opening amounts of a plurality of doors (step S201).

After acquiring the door opening amounts of the plurality of doors, the opening amount acquiring unit 12 acquires installation position information of each door (step S202). The installation position information is, for example, information about the installation position of the door, such as between indoors and outdoors, between indoors, and in the north, south, east, and west of a building.

After acquiring the installation position information of each door, the opening amount acquisition unit 12 weights the door opening amount of each door based on the acquired installation position information (step S203).

In the weighting, for example, the weighting factor of the opening amount of the door that separates the indoors and the outdoors may be made larger than the weighting factor of the opening amount of the door that separates the indoors. Alternatively, by interlocking with a wind sensor, the weighting factor of the opening amount of the door with strong wind speed toward the interior may be made larger than the weighting factor of the opening amount of the door with weak wind speed. By performing such weighting, the door opening amount of the door, which greatly affects the ventilation state of the closed space, can be largely reflected in the determination of the ventilation amount.

After weighting the door opening amount of each door, the opening amount acquisition unit 12 determines the sum of the weighted door opening amounts of each door as the final door opening amount (step S204). The ventilation amount is determined based on the determined final door opening amount.

According to the fourth modification, in addition to the effects of the configuration of FIG. 1, it is possible to obtain the door opening amount in consideration of the relationship with the outside of the closed space.

(Fifth Modification)
Next, a fifth modification will be described in which the door opening amount is acquired in consideration of the length of stay and the height of the door. FIG. 9 is a flowchart showing an operation example of the ventilation system 1 according to the fifth modified example of this embodiment. The flowchart of FIG. 9 is repeated as necessary. The basic configuration of the ventilation system 1 according to the fifth modification is the same as that of FIG. 6, and the flowchart of FIG. 9 is implemented with the configuration of FIG.

As shown in FIG. 9, after the target value acquisition unit 17 acquires the ventilation amount target value (step S1), the opening amount acquisition unit 12 integrates the door position and the dwell time of the door at the door position. By doing so, the door opening amount is obtained (step S23).

Further, the opening amount correction information acquisition unit 14 acquires door height information as the opening amount correction information (step S91).

After the door height information is acquired, the ventilation amount control unit 13 makes the door opening amount acquired by the opening amount acquisition unit 12 proportional to the door height information acquired by the opening amount correction information acquisition unit 14. The amount of door opening is corrected by multiplying by a coefficient to correct (step S101).

After correcting the door opening amount, the ventilation amount control unit 13 calculates the current ventilation amount based on the corrected door opening amount (step S3). Thereafter, steps S4 to S8 are executed in the same manner as in the flowchart of FIG.

According to the fifth modified example, in addition to the effects of the configuration of FIG. Accuracy can be improved.

(Sixth modification)
Next, a sixth modified example for correcting the ventilation amount will be described. FIG. 10 is a block diagram showing a ventilation system 1 according to a sixth modification of this embodiment.

As shown in FIG. 10, the ventilation system 1 according to the sixth modification further includes a ventilation amount correction information acquisition section 15 in addition to the configuration shown in FIG. The ventilation amount correction information acquisition unit 15 acquires ventilation amount correction information for correcting the ventilation amount.

The ventilation amount correction information includes, for example, the air pressure difference between the inside and outside of the closed space, the temperature difference from the appropriate temperature of the closed space, the door height, the opening width of the door, the environment outside the closed space, the ventilation amount, and the ventilation amount target value. may be the difference of

The ventilation amount correction information acquisition unit 15 may be, for example, a storage unit of an automatic door controller, a pressure sensor, a temperature sensor, a wind sensor, or the like. At least part of the ventilation amount correction information acquisition unit 15 may be configured by software.

The ventilation amount control unit 13 corrects the ventilation amount when increasing the ventilation amount (that is, the amount of increase in the ventilation amount) based on the ventilation amount correction information acquired by the ventilation amount correction information acquisition unit 15 . Then, the ventilation amount control section 13 increases the ventilation amount of the ventilation section 11 with the corrected ventilation amount.

For example, when it is desired to suppress ventilation due to a temperature difference in which the temperature outside the closed space is higher than the appropriate temperature inside the closed space, the ventilation amount control unit 13 corrects the ventilation amount downward. By doing so, the amount of increase in ventilation may be decreased with respect to a predetermined reference amount of increase. On the other hand, if there is a temperature difference such that the temperature outside the closed space is lower than the appropriate temperature inside the closed space and it is desired to promote ventilation, the ventilation amount control unit 13 corrects the ventilation amount to increase. By doing so, the increase amount of the ventilation amount may be increased with respect to the reference increase amount.

Note that the ventilation amount control unit 13 may correct the ventilation amount when decreasing the ventilation amount based on the ventilation amount correction information acquired by the ventilation amount correction information acquisition unit 15 . That is, the ventilation amount control unit 13 may increase or decrease the decrease amount of the ventilation amount with respect to a predetermined reference decrease amount based on the ventilation amount correction information. Then, the ventilation amount control section 13 may decrease the ventilation amount by the ventilation section 11 with the corrected ventilation amount.

Next, an operation example of the ventilation system 1 according to the sixth modification will be described. FIG. 11 is a flow chart showing an operation example of the ventilation system 1 according to the sixth modification of the present embodiment. The flowchart of FIG. 11 is repeated as necessary.

As shown in FIG. 11, when it is determined to increase or decrease the ventilation amount (steps S5 and S6), the ventilation amount correction information acquisition unit 15 acquires ventilation amount correction information (step S11). On the other hand, when it is decided to maintain the ventilation amount (step S7), the ventilation amount control section 13 causes the ventilation amount changing section 18 to maintain the ventilation amount of the ventilation section 11 according to the determination (step S8).
