Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air-conditioning facility for adjusting the temperature of an air-conditioning target area by adjusting the supply air volume by a variable air volume device, and more specifically, the deviation between the target temperature and the detected area temperature of the air-conditioning target area. With respect to the target deviation range in which the upper and lower limit deviation values are set, and the air volume adjustment range in which the upper and lower limit air volume values are set for the air volume, the air volume value corresponding to the measured value of the deviation is set as the target air volume value. Then, the present invention relates to an air conditioning equipment equipped with a variable air volume device for automatically adjusting the air supply amount to the air conditioning target region to the target air amount value by adjusting a damper opening degree in the air supply air passage to the air conditioning target region.

2. Description of the Related Art Conventionally, in a variable air volume device (so-called VAV) used in the above-mentioned air conditioning equipment, a setting operation section is provided in the main body of the variable air volume device installed in the air supply passage to the air conditioning target area. The target deviation range Ze
Upper limit air volume value qmax of the air volume adjustment range Zq corresponding to
(That is, the maximum adjustment value of the supply air volume q, see FIG. 2 (a)) has been made possible to change the setting, when delivering the air volume control device to the construction site of the air conditioning equipment, or When installing a variable air volume device in the air supply air passage at the construction site, etc.
By the operation of the setting operation section in the apparatus main body section, the upper limit air flow rate value qmax of the air flow rate adjustment range Zq is set to an appropriate value according to the cooling / heating load characteristics (maximum load value, load fluctuation steepness, etc.) of the corresponding air conditioning target area. I was trying to do it.

[0003]

However, in general, the air flow control device is installed together with the duct that forms the air supply air passage in a place that is difficult for people to access, such as in the ceiling or inside the piping shaft. When the air-conditioning load characteristics of the air conditioning target area change due to changes in the number of people or the number of people accommodated, the upper limit air volume value qmax is changed in the device body of the air volume changing device according to the change in the load characteristics, and the device characteristics of the air volume changing device are changed. It is not easy to adapt (that is, the adjustment characteristics for the supply air volume and the zone temperature) to the changed load characteristics, and in particular for ordinary residents, such setting change operation is actually impossible. Often, this point is inferior in functionality,
Consequently, there is a problem that the air-conditioning performance is deteriorated as shown in the following examples (a) to (c) because the device characteristics of the air flow rate changer become incompatible with the changed load characteristics.

(A) The maximum value of the load range becomes large due to the change of the load characteristic, so that the maximum adjustment value of the supply air amount becomes relatively small with respect to the maximum load value, and the load cannot be increased (ie, A situation occurs in which the deviation e does not converge to the target deviation range Ze). (B) Since the load change tendency becomes steep due to the change in load characteristics, the amount of adjustment of the supply air volume q with respect to the change in the deviation e per unit amount (in other words, the damper opening degree) is seen from the steep load change tendency. Even if the deviation e can be converged to the target deviation range Ze, the zone temperature change due to the load change becomes conspicuous even if the adjustment amount of θ is relatively small. (C) Contrary to (b) above, since the load fluctuation tendency becomes slower due to the change in the load characteristic, the supply air flow rate q per unit quantity change of the deviation e is seen from the slow load fluctuation tendency.
The adjustment amount (adjustment amount of the damper opening θ) is relatively large, and unstable minute fluctuations in the supply state and the zone temperature become conspicuous.

If the change in the load characteristic is already predicted at the time of facility planning, the change in the load characteristic is set in advance in setting the upper limit air flow value qmax in the main body of the apparatus by a person involved in the construction work. Expected upper limit air flow value qmax
However, in such a case, since the setting has a margin of greatest common divisor for the predicted multiple types of load characteristics, the degree of agreement of the device characteristics for each load characteristic is low as a whole. Therefore, in this respect, the same problem as above has occurred.

In view of the above situation, the basic object of the present invention is to make it possible to easily change the device characteristics of a variable air volume device according to changes in load characteristics. In addition, in order to achieve this basic objective, rationalize the air supply fan output adjustment when changing the device characteristics of the air flow rate control device, facilitate management of multiple air flow control devices, and determine the conditions within the air conditioning target area. However, it is an additional object to make it possible to easily change the device characteristics of the air flow rate changing device.

The remote control of the air flow rate control device 9 allows the air flow rate adjustment range Zq to have an upper limit air flow rate value qmax or a lower limit air flow rate value q.
It is possible to change the setting of min as appropriate.

That is, the upper limit air volume value qmax or the lower limit air volume value q of the air volume adjustment range Zq corresponding to the target deviation range Ze.
The setting of min can be changed to change the device characteristics of the air flow rate changing device 9 as appropriate by remote control.

[Operation of Second Characteristic Configuration] In the second characteristic configuration (see FIG. 2B), the upper limit air volume value qmax of the air volume adjustment range Zq is fixed with the lower limit air volume value qmin fixed in accordance with the upper limit change command. When the setting is changed, the device characteristic of the variable air volume changing device can be changed as follows with this upper limit change command.

That is, the upper limit air flow value q
In the case of changing the setting of max to the increase side, the lower limit load value of the allowable load range Zg (that is, the compatible cooling and heating load range) in which the deviation e can be adjusted within the target deviation range Ze by adjusting the supply air volume of the air flow rate changing device. gmin is the lower limit air flow value qmin
This allowable load range Zg is fixed by fixing
The upper limit load value gmax of changes with the increase of the upper limit air flow value qmax, and the allowable load range Zg expands on the upper limit side. Further, the air flow rate adjustment range Zq is expanded by the increase of the upper limit air flow rate value qmax, so that the adjustment amount of the supply air flow rate q with respect to the change of the deviation e per unit amount (in other words, the damper opening adjustment amount in the air flow rate device). Grows larger.

On the other hand, the upper limit air flow value qm
When changing the setting of ax to the decreasing side, the allowable load range Z
While the lower limit load value gmin of g is fixed by fixing the lower limit air flow value qmin, the upper limit load value gmax of the allowable load range Zg changes to the decreasing side as the upper limit air flow value qmax decreases, and the allowable load range Zg changes to the upper limit side. However, since the air volume adjustment range Zq is reduced by the decrease in the upper limit air volume value qmax, the adjustment amount (damper opening adjustment amount) of the supply air amount q with respect to the change of the deviation e per unit amount is reduced.

[Operation of Third Characteristic Configuration] In the third characteristic configuration (see FIG. 3), the upper limit air flow rate value qma is generated in response to the lower limit change command.

When changing the setting of min to the decreasing side, the lower limit load value gmin changes to the decreasing side as the lower limit air flow value qmin decreases while the upper limit load value gmax of the allowable load range Zg is fixed by fixing the upper limit air flow value qmax. However, the allowable load range Zg expands on the lower limit side. In addition, the lower limit air flow value qmi
By expanding the air volume adjustment range Zq by the decrease of n, the adjustment amount (damper opening adjustment amount) of the supply air amount q with respect to the change of the deviation e per unit amount becomes large.

On the other hand, the lower limit air flow value qm
When the setting of in is increased, the allowable load range Z
While the upper limit load value gmax of g is fixed by fixing the upper limit air flow value qmax, the lower limit load value gmin of the allowable load range Zg changes to the increasing side with the increase of the lower limit air flow value qmin, and the allowable load range Zg decreases to the lower limit side. However, since the air volume adjustment range Zq is reduced by the increase of the lower limit air volume value qmin, the adjustment amount (damper opening adjustment amount) of the supply air amount q with respect to the change of the deviation e per unit amount is reduced.

[Operation of Fourth Characteristic Configuration] In the fourth characteristic configuration, a predetermined interlocking relationship between the upper limit air flow rate value qmax and the lower limit air flow rate value qmin, such as when the change form of the load characteristic in the air conditioning target region is recognized in advance. By setting the interlocking relationship according to the change form of the load characteristics, it is only necessary to give an interlocking change command when the load characteristics change, and both the upper and lower limit airflow values in a form that conforms to the change of the load characteristics. Allows you to change settings.

In the fourth characteristic structure, the device characteristics of the variable air volume changing device can be changed as shown in the following (A) to (F) depending on what kind of relationship is adopted as the predetermined interlocking relationship. it can.

(A) As the predetermined interlocking relationship, in accordance with the interlocking change command, the change amount of the upper limit air flow value qmax is made larger than the change amount of the lower limit air flow value qmin by a set ratio, and the upper limit of the air flow rate adjustment range Zq. If the interlocking relationship is adopted such that the airflow rate value qmax and the lower limit airflow rate value qmin are set and changed in the same direction (see FIG. 4), the interlocking change command can change the apparatus characteristics of the variable air volume apparatus as follows.

That is, when both the upper and lower limit airflow values qmax and qmin are set and changed to the increasing side by the interlocking change command, like the upper and lower limit airflow values qmax and qmin.
The upper limit load value gmax rather than the change amount of the lower limit load value gmin
In the form in which the change amount of is increased by the set ratio, both the upper and lower limit load values gmax and gmin of the allowable load range Zg change to the increasing side, and the allowable load range Zg shifts to the large load side with the expansion.

By expanding the air volume adjustment range Zq by the difference in the change amount of n, the adjustment amount (damper opening adjustment amount) of the supply air amount q with respect to the change of the deviation e per unit amount becomes large.

On the other hand, the upper and lower limit air flow value q
When both max and qmin are changed to the decreasing side, the change amount of the upper limit load value gmax is larger than the change amount of the lower limit load value gmin by the set ratio, like the upper and lower limit air flow value values qmax and qmin. Both the upper and lower limit load values gmax and gmin of the allowable load range Zg change to the decreasing side, and the allowable load range Zg shifts to the small load side with a reduction. In addition, the upper and lower limit air flow values qmax, qmin
By reducing the air flow rate adjustment range Zq by the difference in the change amount, the supply air flow rate q with respect to the change Δe of the deviation e per unit amount
Adjustment amount (damper opening adjustment amount) becomes smaller.

(B) As the above-mentioned predetermined interlocking relation, in accordance with the interlocking change command, the change amount of the upper limit air flow value qmax is made larger than the change amount of the lower limit air flow value qmin by a set ratio, and the upper limit of the air flow adjustment range Zq. If the interlocking relationship is adopted such that the airflow value qmax and the lower limit airflow value qmin are set in opposite directions (see FIG. 5), the interlocking change command can change the device characteristics of the airflow rate changing device as follows.

That is, the upper limit air flow value q
In the case of changing the setting of max to the increase side and the lower limit air flow value qmin to the decrease side, these upper and lower limit air flow values qma
Similar to x and qmin, the change amount of the upper limit load value gmax is larger than the change amount of the lower limit load value gmin by the set ratio, and the upper limit load value gmax of the allowable load range Zg changes to the increasing side and the lower limit load value gmin changes to the decrease side, and the allowable load range Zg expands mainly on the upper limit side and on the upper limit side and the lower limit side, respectively. In addition, the upper and lower limit air flow value qma
By expanding the air volume adjustment range Zq by the sum of the changes of x and qmin, the adjustment amount of the supply air amount q (damper opening adjustment amount) with respect to the change of the deviation e per unit amount increases at a large change rate.

On the other hand, the upper limit air flow value qm by the interlocking change command.
When the ax is set to decrease and the lower limit air flow value qmin is changed to increase, these upper and lower limit air flow values qmax,
Similar to qmin, the change amount of the upper limit load value gmax is larger than the change amount of the lower limit load value gmin by a set ratio, and the upper limit load value gmax of the allowable load range Zg changes to the decreasing side and the lower limit load value gmin decreases. The allowable load range Zg decreases to the upper side, mainly on the upper side and the lower side, respectively, while the allowable load range Zg decreases.
By reducing the air volume adjustment range Zq by the sum of the change amounts of in, the air supply air amount q with respect to the change of the deviation e per unit amount
Adjustment amount (damper opening adjustment amount) decreases at a large rate of change.

(C) As the predetermined interlocking relation, in accordance with the interlocking change command, the change amount of the lower limit air flow value qmin is made larger than the change amount of the upper limit air flow value qmax by a set ratio, and the upper limit of the air flow rate adjustment range Zq is set. If the interlocking relationship is adopted such that the airflow value qmax and the lower limit airflow value qmin are set and changed in the same direction (see FIG. 6), the device characteristics of the air volume changing device can be changed as follows by the interlocking change command.

That is, when both the upper and lower limit airflow values qmax and qmin are changed to the decreasing side by the interlocking change command, like the upper and lower limit airflow values qmax and qmin,
Lower limit load value gmin than change amount of upper limit load value gmax
In the form in which the change amount of is increased by the set ratio, both the upper and lower limit load values gmax and gmin of the allowable load range Zg are changed to the decreasing side, and the allowable load range Zg is shifted to the small load side while being expanded. In addition, the upper and lower limit air volume values qmax, qmi
By expanding the air volume adjustment range Zq by the difference in the change amount of n, the adjustment amount (damper opening adjustment amount) of the supply air amount q with respect to the change of the deviation e per unit amount becomes large.

On the other hand, the upper and lower limit air flow value q
In the case where both max and qmin are changed to the increasing side, the change amount of the lower limit load value gmin is larger than the change amount of the upper limit load value gmax by the set ratio, like the upper and lower limit air flow value values qmax and qmin. Both the upper and lower limit load values gmax and gmin of the allowable load range Zg change to the increasing side, and the allowable load range Zg shifts to the large load side with a reduction. In addition, the upper and lower limit air flow values qmax, qmin
By reducing the air flow rate adjustment range Zq by the difference in the change amount, the adjustment amount (damper opening adjustment amount) of the supply air flow rate q with respect to the change of the deviation e per unit amount is reduced.

(D) As the predetermined interlocking relationship, in accordance with the interlocking change command, the change amount of the lower limit air flow value qmin is made larger than the change amount of the upper limit air flow value qmax by a set ratio, and the upper limit of the air flow adjustment range Zq. If an interlocking relationship is adopted in which the air flow rate value qmax and the lower limit air flow rate value qmin are changed in opposite directions (see FIG. 7), the interlocking change command can change the device characteristics of the air flow rate changing device as follows.

That is, the upper limit air flow value q
In the case of changing the setting of max to the increase side and the lower limit air flow value qmin to the decrease side, these upper and lower limit air flow values qma
Similar to x and qmin, the change amount of the lower limit load value gmin is larger than the change amount of the upper limit load value gmax by a set ratio, and the upper limit load value gmax of the allowable load range Zg changes to the increasing side and the lower limit load value gmin changes to the decrease side, and the allowable load range Zg expands mainly on the lower limit side and on the upper limit side and the lower limit side, respectively. In addition, the upper and lower limit air flow value qma
By expanding the air volume adjustment range Zq by the sum of the changes of x and qmin, the adjustment amount of the supply air amount q (damper opening adjustment amount) with respect to the change of the deviation e per unit amount increases at a large change rate.

On the other hand, the upper limit air flow value qm
When the ax is set to decrease and the lower limit air flow value qmin is changed to increase, these upper and lower limit air flow values qmax,

The allowable load range Zg changes to the increasing side, and the allowable load range Zg decreases on the lower limit side mainly on the upper limit side and the lower limit side.
By reducing the air volume adjustment range Zq by the sum of the change amounts of in, the air supply air amount q with respect to the change of the deviation e per unit amount
Adjustment amount (damper opening adjustment amount) decreases at a large rate of change.

(E) As the above-mentioned predetermined interlocking relationship, the upper limit air volume value qmax of the air volume adjusting range Zq in accordance with the interlocking change command.
If the interlocking relationship is adopted such that the lower limit air flow rate value qmin and the lower limit air flow rate value qmin are changed in the same direction by the same change amount (see FIG. 8), the device characteristic of the variable air flow rate device can be changed as follows by the interlocking change command. .

That is, when both the upper and lower limit airflow values qmax and qmin are changed to the increasing side by the interlocking change command, like the upper and lower limit airflow values qmax and qmin,
The upper and lower limit load values gmax and gmin of the allowable load range Zg both change to the increasing side by the same amount, and the allowable load range Zg shifts to the large load side while keeping the range width constant. Further, by keeping the range width of the air volume adjustment range Zq constant,
The adjustment amount (damper opening adjustment amount) of the supply air amount q with respect to the change of the deviation e per unit amount is kept constant.

On the other hand, the upper and lower limit air flow value q
When both max and qmin are changed to the decreasing side, the upper and lower limit load values gmax and gmin of the allowable load range Zg both change to the decreasing side by the same amount as the upper and lower limit air flow values qmax and qmin. The range Zg shifts to the small load side while keeping the range width constant. As in the case of the above setting change to the increasing side, by keeping the range width of the air volume adjustment range Zq constant, the adjustment amount (the damper opening adjustment amount) of the supply air amount q with respect to the change of the deviation e per unit amount. ) Is kept constant.

(F) As the predetermined interlocking relation, the upper limit air volume value qmax of the air volume adjusting range Zq in accordance with the interlocking change command.
If the interlocking relationship is adopted in which the setting and the lower limit airflow value qmin are changed in opposite directions by the same change amount (see FIG. 9), the device characteristics of the airflow rate changing device can be changed as follows by the interlocking change command. .

That is, the upper limit air flow value q

The max changes to the increasing side and the lower limit load value gmax changes to the decreasing side by the same amount, and the allowable load range Zg expands equally on the upper limit side and the lower limit side. Also, the upper and lower limit air flow value q
By expanding the air volume adjustment range Zq by the sum of the change amounts of max and qmin, the adjustment amount of the supply air amount q (damper opening adjustment amount) with respect to the change of the deviation e per unit amount increases at a large change rate.

On the other hand, the upper limit air flow rate value qm
When the ax is set to decrease and the lower limit air flow value qmin is changed to increase, these upper and lower limit air flow values qmax,
Similar to qmin, the upper limit load value gma of the allowable load range Zg
x decreases and the lower limit load value gmax increases by the same amount, and the allowable load range Zg decreases equally on the upper limit side and the lower limit side.
By reducing the air volume adjustment range Zq by the sum of the change amounts of qmin, the adjustment amount of the supply air amount q (damper opening adjustment amount) with respect to the change of the deviation e per unit amount decreases at a large change rate.

[Operation of Fifth Characteristic Configuration] In the fifth characteristic configuration, the upper limit air volume value qmax of the air volume adjustment range Zq is changed according to the upper limit change command, and the lower limit air volume of the air volume adjustment range Zq is changed according to the lower limit change command. By changing the setting of the value qmin, the device characteristics of the variable air volume control device can be changed to those of the above-described second to fourth characteristic configurations with an appropriate combination of the setting change of the upper limit air flow value qmax and the setting change of the lower limit air flow value qmin. It can be modified in any modified form including various modified forms shown in the operation.

[Operation of Sixth Characteristic Configuration] In the sixth characteristic configuration (see FIGS. 1 and 2), the output f of the air supply fan 3 is adjusted in accordance with the adjustment status of the damper opening θ in the air flow volume control device 9. By providing the fan control means 11B, the damper opening θ is adjusted within a desired suitable opening range in the adjustment of the supply air volume of the variable air volume device 9 by adjusting the damper opening.

That is, although the damper opening θ is at the maximum opening, the supply air volume q does not reach the target air volume value qs because the output f of the air supply fan 3 is insufficient. On the contrary, since the supply fan output f is excessively large,
It is prevented by the above fan output adjustment based on the adjustment status of the damper opening θ that the throttle opening of the damper opening θ required for adjusting the supply air volume q to the target air flow value qs becomes large and causes a large pressure loss. To do.

Then, such a fan control means 11B
In contrast to the above, the forced air supply fan output change that prioritizes the air supply fan output adjustment depending on the damper opening adjustment state is linked to the above-described setting change of the upper limit air flow value qmax or the lower limit air flow value qmin. By providing the fan linking means 11D to be executed by the control means 11B, the target air flow rate value qs (corresponding to the measured value of the deviation e at that time according to the change of the air flow rate adjustment range Zq by changing the setting of the upper limit air flow value qmax or the lower limit air flow value qmin). The forced air supply fan output change described above is used to quickly shift the output f of the air supply fan 3 to an output value that matches the new target air flow value qs.

That is, in the normal fan output control based on the adjustment status of the damper opening θ, the fan output f is adjusted depending on the result of the damper opening θ being too large or too small, and the fan output adjustment In order to prevent destabilization, the response speed of the fan output adjustment is also limited to an appropriate value. Therefore, the upper limit air flow value qmax or the lower limit air flow value qmin.
When there is a change in the setting of the air supply fan 3 with a considerable time delay with respect to the change in the target air flow rate value qs due to the change in the setting.
Output f is adjusted, and this delay is due to the target air flow value qs
The larger the change width of the fan speed becomes, the larger the change speed becomes due to the limitation of the response speed. Due to such a delay in the fan output adjustment, after the setting of the upper limit air flow value qmax or the lower limit air flow value qmin is changed, the power supply due to the fan output incompatibility is changed. Insufficient air volume and excessive air supply volume cause inconvenience.

On the other hand, in the sixth characteristic configuration, when the setting of the upper limit air volume value qmax or the lower limit air volume value qmin is changed,
Air supply fan 3 with the above-mentioned forced air supply fan output change
By rapidly shifting the output f from the output f to an output value that matches the new target air flow rate qs, the inconvenience due to the delay in the fan output adjustment as described above is prevented.

[Operation of Seventh Characteristic Configuration] In the seventh characteristic configuration (see FIG. 1), a change command is given to the centralized setting unit 13 so that a desired one of the plurality of air volume changing devices 9 can be operated remotely from one location. It is possible to appropriately change the upper limit air flow value qmax or the lower limit air flow value qmin of the variable air volume device.

[Operation of Eighth Characteristic Configuration] In the eighth characteristic structure, by giving a change command in the air conditioning target area, the upper limit air volume value qmax or the lower limit air volume value qmin of the air volume changing device corresponding to the air conditioning target area is appropriately changed. Allows you to change settings.

【The invention's effect】

[Effect of First Characteristic Configuration] According to the first characteristic configuration of the present invention, even if the airflow rate changing device is installed in a location that is difficult for a person to approach, the upper limit airflow rate value by remote control is applied to the characteristic change of the cooling and heating load. Alternatively, by changing the setting of the lower limit air flow rate value, it is possible to easily change the device characteristic of the air flow rate changing device to one that conforms to the changed load characteristic, whereby good air conditioning can be performed regardless of the change in the load characteristic.

[Effect of Second Characteristic Configuration] According to the second characteristic configuration of the present invention, as the device characteristic change of the air flow rate changing device by the upper limit change command, (a1) the supply air flow rate adjustment amount with respect to the change per unit amount of the deviation. While the (damper opening adjustment amount) is increased, the device characteristic is changed so that the allowable load range is expanded on the upper limit side, and (a2) On the contrary, the allowable load range is reduced on the upper limit side, while the deviation per unit amount is increased. Since the device characteristic can be changed to decrease the supply air flow rate adjustment amount (damper opening adjustment amount) with respect to the change, the load characteristic change (b1 )
On the contrary, after changing the device characteristic of the variable air volume device with a particularly high adaptability to the load characteristic change (b2) in which the load fluctuation tendency becomes slower in the form of contraction on the maximum value side of the load range, conversely. The load characteristics of can be accurately adapted.

That is, regarding the load characteristic change of the above (b1), the supply air amount adjustment amount (damper opening adjustment amount) relative to the change per unit amount of the deviation relative to the steep load change tendency is relatively small. As the air flow rate is adjusted, the temperature change due to the load change becomes conspicuous, or the load range expanded on the maximum value side deviates from the allowable load range and the deviation does not converge to the target deviation range. This can be prevented by changing the device characteristics in (a1) above.

Regarding the load characteristic change of (b2) above, the supply air volume adjustment amount (damper opening adjustment amount) relative to the change per unit amount of the deviation is relatively excessive with respect to the slowed load fluctuation tendency. If the air flow rate is adjusted and unstable minute fluctuations in the air supply state and the zone temperature become noticeable,
This can be prevented by changing the device characteristics in 2).

[Effect of Third Characteristic Configuration] According to the third characteristic configuration of the present invention, as the device characteristic change of the air flow rate changing device by the lower limit change command, (a3) the supply air flow rate adjustment amount with respect to the change per unit amount of the deviation. While the (damper opening adjustment amount) is increased, the device characteristic is changed so that the allowable load range is expanded on the lower limit side, and (a4) On the contrary, the allowable load range is decreased on the lower limit side, while the deviation per unit amount is increased. Since the device characteristic can be changed to reduce the supply air flow rate adjustment amount (damper opening adjustment amount) with respect to the change, the load characteristic change (b3 )
On the contrary, after changing the device characteristics of the variable air volume control device with a particularly high adaptability to the load characteristic change (b4) in which the load fluctuation tendency becomes slower in the form accompanied by reduction on the minimum value side of the load range, The load characteristics of can be accurately adapted.

That is, regarding the load characteristic change of the above (b3), the supply air amount adjustment amount (damper opening adjustment amount) relative to the change per unit amount of the deviation relative to the steep load change tendency is relatively small. There is a situation in which the temperature change due to load fluctuation becomes noticeable as the air flow rate is adjusted, and the load range expanded on the minimum value side deviates from the allowable load range and the deviation does not converge to the target deviation range. This can be prevented by changing the device characteristics in (a3) above.

Regarding the load characteristic change of the above (b4), the supply air flow rate adjustment amount (damper opening adjustment amount) relative to the variation per unit amount of the deviation is relatively excessive with respect to the slowed load fluctuation tendency. If the air flow rate is adjusted and unstable minute fluctuations in the air supply state and the zone temperature become noticeable,
This can be prevented by changing the device characteristics in 4).

[Effects of Fourth Characteristic Configuration] According to the fourth characteristic structure of the present invention, both the upper and lower limit airflow values can be easily changed by simply giving an interlocking change command in a form in accordance with a change in load characteristics. Therefore, the device characteristics of the air flow rate changer can be appropriately adapted to the changed load characteristics.

Then, as the predetermined interlocking relationship, the above-mentioned (A)
In the case of adopting the interlocking relationship indicated by, the change in the device characteristics of the air flow rate changing device by the interlocking change command causes (a5) increase and allowance of the supply air flow rate adjustment amount (damper opening adjustment amount) with respect to the change per unit amount of deviation. Change the device characteristics to shift the allowable load range to the large load side while enlarging the load range, and (a
6) On the contrary, the device characteristics can be changed to shift the allowable load range to the small load side while reducing the supply air volume adjustment amount (damper opening adjustment amount) and the allowable load range with respect to the deviation per unit amount of the deviation. Therefore, the load characteristic change (b5) such that the load range shifts to the large load side in a form accompanied by the steep load fluctuation tendency and the expansion of the load range, and conversely, the slower load fluctuation tendency and the reduction of the load range are performed. With such a configuration, the device characteristic of the air flow rate changing device can be accurately adapted to the changed load characteristic with a particularly high adaptability to the load characteristic change (b6) such that the load range shifts to the small load side.

That is, regarding the load characteristic change of the above (b5), the supply air amount adjustment amount (damper opening adjustment amount) relative to the change per unit amount of deviation relative to the steep load change tendency is relatively small. There is a situation in which the air temperature adjustment makes the zone temperature change due to load variation noticeable, and the load range that has shifted to the large load side due to expansion deviates from the allowable load range and the deviation does not converge to the target deviation range. This can be prevented by changing the device characteristics in (a5) above.

On the other hand, with respect to the load characteristic change of the above (b6), the supply air volume adjustment amount (damper opening adjustment amount) relative to the change per unit amount of the deviation is relatively excessive with respect to the slowed load fluctuation tendency. The air flow rate adjustment becomes noticeable and unstable minute fluctuations in the air supply state and the zone temperature become noticeable, and the load range shifted to the small load side due to reduction deviates from the allowable load range and the deviation is the target deviation range. It is possible to prevent the situation in which the above condition is not converged from occurring by changing the device characteristics in (a6) above.

In the case where the interlocking relationship shown in (B) above is adopted as the predetermined interlocking relationship, the device characteristic of the air flow rate changing device is changed by the interlocking change command, and (a7) air supply for a change in deviation per unit amount is performed. Along with an increase in the airflow adjustment amount (damper opening adjustment amount) at a large rate of change, a device characteristic change that expands the allowable load range mainly on the upper limit side and the upper limit side, respectively, and (a8) Allows conversely Device characteristics that reduce the supply air flow rate adjustment amount (damper opening adjustment amount) with respect to the change per unit amount of deviation at a large rate of change while reducing the upper limit side and the lower limit side mainly on the upper limit side of the load range Since the change can be made, the load characteristic changes such that the load range is expanded mainly on the maximum value side and the minimum value side in a form accompanied by a drastic sharpening of the load fluctuation tendency (b7).
On the contrary, for the load characteristic change (b8) in which the load fluctuation tendency is greatly slowed down in the form involving reduction on the maximum value side and the minimum value side mainly on the maximum value side of the load range, With a particularly high adaptability, it is possible to accurately adapt the device characteristics of the variable air volume device to the changed load characteristics.

That is, regarding the load characteristic change of the above (b7), the supply air volume adjustment amount (damper opening adjustment amount) relative to the change per unit amount of the deviation is relatively large with respect to the load fluctuation tendency sharply sharpened. Insufficient adjustment of the supply air volume makes the temperature change due to load fluctuation noticeable, and the load range expanded mainly on the maximum value side and the minimum value side deviates from the allowable load range. As a result, the situation where the deviation does not converge to the target deviation range occurs.
It can be prevented by changing the device characteristics.

On the other hand, regarding the load characteristic change of the above (b8), the supply air flow rate adjustment amount (damper opening adjustment amount) relative to the change per unit amount of the deviation is relatively large with respect to the load fluctuation tendency that is greatly slowed down. It is possible to prevent an excessively small adjustment of the supply air volume from causing the unstable minute fluctuations of the supply air condition or the zone temperature to become conspicuous by the above-mentioned (a8) device characteristic change.

In the case where the interlocking relationship shown in (C) above is adopted as the predetermined interlocking relationship, the device characteristic of the air flow rate changing device is changed by the interlocking change command, and (a9) the air supply for the change per unit amount of the deviation is performed. Along with the increase of the air flow adjustment amount (damper opening adjustment amount) and the expansion of the allowable load range, the device characteristic is changed to shift the allowable load range to the small load side.
0) Conversely, the device characteristics can be changed to shift the allowable load range to the large load side while reducing the supply air flow rate adjustment amount (damper opening adjustment amount) and the allowable load range with respect to the deviation per unit amount of the deviation. Therefore, the load characteristic change (b9) such that the load range shifts to the small load side in a form accompanied by the steep load fluctuation tendency and the expansion of the load range, or conversely, the slower load fluctuation tendency and the reduction of the load range. It is possible to accurately adapt the device characteristic of the variable air volume device to the changed load characteristic with a particularly high adaptability to the load characteristic change (b10) in which the load range shifts to the large load side in the accompanying form.

That is, regarding the load characteristic change of the above (b9), the supply air amount adjustment amount (damper opening adjustment amount) relative to the change per unit amount of the deviation is relatively small with respect to the steep load change tendency. There is a situation in which the air temperature adjustment becomes noticeable and the temperature change due to load fluctuation becomes noticeable, and the load range that has shifted to the small load side due to expansion deviates from the allowable load range and the deviation does not converge to the target deviation range. This can be prevented by changing the device characteristics in (a9) above.

On the other hand, regarding the load characteristic change of the above (b10), the supply air volume adjustment amount (damper opening adjustment amount) with respect to the change per unit amount of the deviation with respect to the slowed load fluctuation tendency.
Is a relatively excessive amount of air supply adjustment, and unstable minute fluctuations in the air supply state and zone temperature become noticeable, and the load range that has shifted to the large load side due to reduction deviates from the allowable load range. Then, it is possible to prevent a situation in which the deviation does not converge to the target deviation range from occurring by changing the device characteristics in (a10) above.

When the interlocking relationship shown in (D) above is adopted as the predetermined interlocking relationship, the device characteristics of the air flow rate changing device are changed by the interlocking change command, and (a11) air supply for a change in deviation per unit amount is supplied. Along with an increase in the rate of change of the air flow rate adjustment amount (damper opening adjustment amount), the allowable load range is expanded mainly on the lower limit side, mainly on the upper limit side and the lower limit side. A device characteristic that reduces the supply air flow rate adjustment amount (damper opening adjustment amount) with respect to the change per unit amount of deviation at a large rate of change while reducing the load range mainly on the lower limit side and the upper limit side. Since the change can be made, a load characteristic change (b1) in which the load range is expanded mainly on the maximum value side and the minimum value side in a form accompanied by a drastic sharpening of the load fluctuation tendency (b1
1) Or, conversely, in a load characteristic change (b12) in which the load fluctuation tendency is greatly slowed down in a form accompanied by reduction on the maximum value side and the minimum value side mainly on the minimum value side of the load range. In contrast,
With a particularly high adaptability, it is possible to accurately adapt the device characteristics of the variable air volume device to the changed load characteristics.

That is, regarding the load characteristic change of (b11) above, the supply air volume adjustment amount (damper opening adjustment amount) relative to the change per unit amount of the deviation is relatively large with respect to the load fluctuation tendency that is sharply steep. Insufficient air supply air volume adjustment will make the zone temperature change due to load fluctuation noticeable, and the load range expanded mainly on the minimum value side and the maximum value side will deviate from the allowable load range. As a result, a situation in which the deviation does not converge to the target deviation range occurs.
This can be prevented by changing the device characteristics in 1).

On the other hand, regarding the load characteristic change of the above (b12), the supply air flow rate adjustment amount (damper opening adjustment amount) relative to the change per unit amount of the deviation is relatively large with respect to the load fluctuation tendency that is greatly slowed. It is possible to prevent the unstable minute fluctuations of the air supply state and the region temperature from becoming conspicuous by the excessive adjustment of the air supply air volume by changing the device characteristics in (a12) above.

When the interlocking relationship shown in (E) above is adopted as the predetermined interlocking relationship, the device characteristics of the air flow rate changing device are changed by the interlocking change command, and (a13) air supply for a change in deviation per unit amount is performed. A device characteristic change that shifts the allowable load range to the large load side while keeping the air volume adjustment amount (damper opening adjustment amount) constant and the allowable load range range constant, and (a14) reverse deviation Change the device characteristics to shift the allowable load range to the small load side while keeping the supply air flow rate adjustment amount (damper opening adjustment amount) constant for the change per unit amount and keeping the allowable load range range constant. Therefore, the load characteristic change (b13) such that the load range shifts to the large load side with little change in the degree of load change or the range width of the load range, or conversely, the degree of load change Load range With respect to the load characteristic change (b14) in which the load range shifts to the small load side in the state where the range width does not change so much, the device characteristic of the air flow rate changing device is changed to the load characteristic after the change. It can be adapted exactly.

That is, regarding the load characteristic change of (b13) above, the load range shifted to the large load side deviates from the allowable load range and the deviation does not converge to the target deviation range while the range width does not change much. The situation can be prevented by changing the device characteristics in (a13) above, and the load characteristics change in (b14) above is shifted to the small load side with little change in the range width. The situation where the load range deviates from the permissible load range and the deviation does not converge to the target deviation range occurs (see a13) above.
It can be prevented by changing the device characteristics.

Even if any load characteristic changes,
In contrast to the fact that the degree of load fluctuations does not change much, the allowable load range is set to a large load side or a small load while maintaining a constant supply air flow rate adjustment amount (damper opening adjustment amount) for changes in deviation per unit amount. Since it is possible to shift to the side, the change in the device characteristics for the purpose of shifting to the allowable load range causes unnecessary changes in the supply air flow rate adjustment amount (damper opening adjustment amount) with respect to changes in the deviation per unit amount, resulting in load fluctuations. It is possible to avoid the inconvenience of being too small or too large with respect to the degree of slowness.

In the case where the interlocking relationship shown in (F) above is adopted as the predetermined interlocking relationship, the device characteristics of the air volume changing device are changed by the interlocking change command, and (a15) air supply for a change in deviation per unit amount is performed. Along with an increase in the air flow rate adjustment amount (damper opening adjustment amount) at a large rate of change, a device characteristic change that expands the allowable load range equally on the upper limit side and the lower limit side, and (a16) conversely the allowable load range Amount of air supply adjustment (damper opening adjustment) with respect to change per unit amount of deviation, with equal reduction on both upper and lower limits of
Can be changed with a large rate of change, the load characteristics can be changed so that the load range is equally expanded on the maximum value side and the minimum value side in a form accompanied by a large sharpening of the load fluctuation tendency ( b15) or, conversely, for a load characteristic change (b16) in which the load fluctuation tendency is greatly slowed down in the form involving reduction on the maximum value side and the minimum value side of the load range,
With a particularly high adaptability, it is possible to accurately adapt the device characteristics of the variable air volume device to the changed load characteristics.

That is, regarding the load characteristic change of the above (b15), the supply air volume adjustment amount (damper opening adjustment amount) relative to the change per unit amount of the deviation is relatively large with respect to the load fluctuation tendency sharply sharpened. Insufficient air supply air volume adjustment makes the zone temperature change due to load fluctuation noticeable, and the expanded load range on the maximum value side and minimum value side deviates from the allowable load range and the deviation is the target deviation. It is possible to prevent the situation in which the range is not converged from occurring by changing the device characteristics in (a15) above.

On the other hand, regarding the load characteristic change of the above (b16), the supply air flow rate adjustment amount (damper opening adjustment amount) is relatively relative to the change per unit amount of the deviation with respect to the load fluctuation tendency that is greatly slowed. It can be prevented by changing the device characteristics in the above (a16) that an excessively large adjustment of the supply air amount causes an unstable minute change in the supply air condition or the zone temperature to become conspicuous.

In addition, in the effects of the above-described second to fourth characteristic configurations, when the device characteristics of the variable air volume device can be adapted to the changed load characteristics with particularly high adaptability (that is,
The optimum example of load characteristic change that can be dealt with has been shown.
The device characteristic changes by these second to fourth characteristic configurations are carried out only for the purpose of changing the upper limit load value of the allowable load range in response to the change of the maximum value of the load range due to the change of the load characteristic. , If the purpose is to change only the lower limit load value of the allowable load range according to the change of the minimum value of the load range due to the change of the load characteristic, or the change of the load characteristic changes the steepness of the load fluctuation. Accordingly, it is also effective in the case where it is carried out only for the purpose of changing the supply air volume adjustment amount (damper opening adjustment amount) with respect to the change of the deviation per unit amount.

[Effect of Fifth Characteristic Configuration] According to the fifth characteristic configuration of the present invention, the device characteristics of the variable air volume control device are changed by appropriately changing the setting of the upper limit air flow rate and the setting of the lower limit air flow rate. Since it can be changed in any modified form including various modified forms according to the second to fourth characteristic configurations, even if the load characteristic changes of any form, the device characteristics of the variable air volume device are appropriately adapted to the changed load characteristics. Thus, the air conditioning performance can be maintained high.

[Effect of Sixth Characteristic Configuration] According to the sixth characteristic configuration of the present invention, normally, the damper opening of the air volume changing device is adjusted to a suitable opening degree by adjusting the output of the air supply fan based on the adjustment status of the damper opening degree. However, when changing the setting of the upper limit airflow value or the lower limit airflow value (that is, changing the device characteristics of the airflow rate changer), the fan output is changed by the forced air supply fan output change linked to the setting change. High air conditioning that prevents the situation of insufficient supply air volume or excessive supply air volume due to delay in output adjustment from being continued for a while, and that the supply air volume can be quickly adjusted to an air volume that matches the changed device characteristics. Performance can be secured.

[Effect of Seventh Characteristic Configuration] According to the seventh characteristic structure of the present invention, the upper limit air volume value or the lower limit air volume value of a desired air volume changing device among a plurality of air volume changing devices can be remotely controlled from one place. Since the setting can be changed appropriately, it is possible to simplify the management work for the plurality of air flow rate changers in the air conditioning equipment in which the plurality of air flow rate changers are dispersedly installed.

[Effect of Eighth Characteristic Configuration] According to the eighth characteristic structure of the present invention, by giving the change command in the air conditioning target area, the upper limit airflow value or the lower limit airflow value of the variable air volume device corresponding to the air conditioning target area. Since it is possible to appropriately change the above, it is possible for an insider in the air conditioning target area to easily and appropriately change the device characteristic of the corresponding variable air volume control device according to the inside area while determining the area inside the air conditioning target area.

Then, the supply air volume q to the corresponding room is adjusted to this target air volume value qs by adjusting the damper opening θ.

That is, in the variable air volume device 9, the room temperature deviation e (measurement value e ') of the corresponding room is biased to the + side (however, in the cooling mode, e = tx-txs, and in the heating mode, e = txs-).
tx) increases the supply air flow rate q to the corresponding room, and decreases the supply air flow rate q to the corresponding room as the room temperature deviation e (measurement value e ′) of the corresponding room is shifted to the − side. The room temperature deviation e of the corresponding room is adjusted within the above target deviation range Ze (in other words, the room temperature tx of the corresponding room is adjusted within a predetermined allowable change range with respect to the target room temperature txs).

The variable air volume device 9 maintains the target air volume value qs at the upper limit air volume value qmax of the air volume adjustment range Zq when the measured value e'of the deviation e is not less than the upper limit deviation value emax of the target deviation range Ze.

On the other hand, 11 is an integrated control device arranged in the airframe of the air conditioner 2 or in the vicinity thereof, 12a is an air supply temperature detector for detecting the temperature ts of the supply air SA, and 12b is a return air temperature for detecting the temperature tr of the return air RA. A detector, 13 is a remote setting device for a variable air volume device that is arranged in the airframe 2 or in the vicinity thereof together with the integrated control device 11, and the integrated control device 11 includes a supply air temperature ts detected by the supply air temperature detector 12a and Return temperature detector 12b
Switching between the cooling mode and the heating mode on the basis of the detected return air temperature tr according to, and the target air flow rate value qs of each air flow rate device 9 obtained from the air flow rate device 9 side via the signal line L. Also, the air supply temperature control unit 11A that adjusts / changes the air supply temperature ts and the damper opening at each time point of each air volume changing device 9 that also obtains information from the air volume changing device 9 side via the signal line L described above. The remote control using the signal line L according to the upper limit change command given to the fan control unit 11B that changes the output f of the air supply fan 3 and the remote setting device 13 for the variable air volume device based on the degree adjustment situation. By the setting control unit 11C for the variable air volume device that sets and changes the air volume adjustment range Zq in each variable air volume device 9, and the fan control unit 11B in association with the setting change of the air volume adjustment range Zq by the upper limit change command. Forced to It is provided with a fan linkage portion 11D to execute the air fan output changes.

The above-mentioned respective parts 11A to 11D in the integrated control device 11 are specifically configured to function as follows.

The supply air temperature control unit 11A determines that the detected return air temperature tr at the start of air conditioning when the operation of the supply air fan 3 is started is equal to or higher than the cooling determination temperature trc (eg, 25 ° C.) (tr).
≧ trc), by specifying the mode for the variable air volume devices 9 using the signal line L, the variable air volume devices 9 are brought into a state in which the air volume adjustment operation is performed in the cooling mode, and the detected supply air temperature ts
By adjusting the cooling output of the temperature control coil 5 based on
The air conditioner operation in the cooling mode for adjusting s to the target air supply temperature tss is started, and the reference air supply temperature tsc for cooling (for example, 15 ° C.) is adopted as the target air supply temperature tss.

Further, the detected return air temperature tr at the start of air conditioning when the operation of the air supply fan 3 is started is the heating determination temperature trw.
In the case of (for example, 21 ° C.) or less (tr ≦ trw), each variable air volume device 9 is set to the air volume adjusting operation in the heating mode by the mode designation using the signal line L, and based on the detected supply air temperature ts. The air conditioner operation in the heating mode in which the supply air temperature ts is adjusted to the target air supply temperature tss by adjusting the heating output of the temperature control coil 5 is started, and the reference air supply temperature tsw for heating is set as the target air supply temperature tss. (Eg 35
℃) is adopted.

It should be noted that the detected return air temperature tr at the start of air conditioning when the operation of the air supply fan 3 is started is the cooling determination temperature trc.
When the temperature is less than and is higher than the heating determination temperature trw (t
For rw <tr <trc), the cooling mode is performed by stopping the temperature control by the temperature control coil 5 and operating the air supply fan 3 only, and if the detected return air temperature tr is equal to or higher than the cooling determination temperature trc. Mode, and if the detected return air temperature tr becomes equal to or lower than the heating determination temperature trw, the above heating mode is executed.

Further, the supply air temperature control section 11A adjusts the supply air temperature ts during the cooling mode or the heating mode by changing the air supply amount device 9 (that is, the corresponding chamber) using the upper limit air flow value qmax as the target air flow value qs. Of the variable air volume device whose deviation e is greater than or equal to the upper limit deviation value emax) is the variable air volume device 9 whose lower limit air flow value qmin is the target air flow value qs (that is, the deviation e of the corresponding room is the lower limit deviation value e).
The target supply air temperature tss is decreased by 1 ° C. in the cooling mode, and the target supply air temperature tss is increased by 1 ° C. in the heating mode each time the air flow amount device becomes less than min. To raise.

Further, the lower limit air volume value qmin is set to the target air volume value q
s is the number of variable air volume devices 9 and the upper limit air flow value qma
The target air supply temperature tss is increased by 1 ° C. in the cooling mode and the target air supply temperature tss is increased by 1 in the heating mode every time the number of variable air volume devices 9 having x as the target air flow value qs is increased by a predetermined ratio or more. Decrease by ℃.

In the change of the target supply air temperature tss, in the cooling mode, when the target supply air temperature tss becomes higher than the detected return air temperature tr plus a predetermined temperature difference (for example, 2 ° C.), The operation of the air conditioner 2 and the air volume adjustment operation of each air volume changing device 9 are switched from the cooling mode to the heating mode. In the heating mode, the target supply air temperature tss subtracts a predetermined temperature difference (for example, 2 ° C.) from the detected return air temperature tr. When the temperature drops to a certain temperature, the operation of the air conditioner 2 and the air volume adjustment operation of each air volume changing device 9 are switched from the heating mode to the cooling mode.

During execution of the cooling mode or the heating mode, the fan control section 11B determines that even one of the air flow rate changing devices 9 has a damper opening increase θ of 100% and further requests the damper opening increase. Then, the output f of the air supply fan 3 is gradually increased, and conversely, the damper opening θ is set to a predetermined intermediate opening (for example, 84% opening) for all the air flow rate changing devices 9.
In the following cases, the output f of the air supply fan 3 is gradually reduced. In this example, the output f of the air supply fan 3 is adjusted to be increased or decreased by inverter control of the fan motor.

Further, when the fan control section 11B increases the fan output f, the air flow rate changing device 9 which requires a further damper opening increase when the damper opening θ is 100%.
In the case where the fan output f is increased at a higher speed as the number of units increases, and the fan output f is similarly reduced, the damper opening θ is equal to or less than a predetermined intermediate opening (for example, 84% opening). The larger the number of the variable air volume devices 9 having the damper opening reduction request among the variable air volume devices 9 of FIG.
Decrease at a great speed.

The remote setting device 13 for the variable air volume device is a centralized setting device that receives a selective upper limit change command for each variable air volume device 9 at one location. 11C, in response to a selective upper limit change command received by the remote setting device 13, the upper limit air amount value qmax of the air amount adjustment range Zq in the selected variable air volume device 9 and the lower limit air amount value qmin are fixed. The setting is changed to the increasing side or the decreasing side as shown by the broken line in (b).

That is, the remote setting device 13 for the variable air volume device,
The setting control unit 11C and the signal line L specify the variable air volume changing device 9 to be changed by a command assigner such as an equipment manager, and specify the necessary change direction and the necessary change amount of the upper limit air flow value qmax. In response to an upper limit change command to the remote setting device 13, the remote setting means for remotely changing the upper limit air volume value qmax of the air volume adjustment range Zq in the specified air volume changing device 9 in the required change direction by the required change amount. Make up K.

The setting change of the upper limit air flow value qmax as described above is performed by changing the purpose of the room or the number of persons accommodated in each room 1a-1.
Although the cooling / heating load characteristic of d changes, it is performed in order to adapt the device characteristic of the corresponding air flow rate changing device 9 to the changed load characteristic. As an example, the first chamber 1a and the second chamber 1b are used. The partition between them is removed, and these first chambers 1a are
When each of the first and second chambers 1b and 1b is used as a meeting room having a larger number of people per room than when it is used as a general living room, the air flow rate changing device 9 for the first and second chambers 1a and 1b is used.
It is possible to change the setting of the upper limit air flow rate value qmax to a larger side than when it is used as a general living room.

The fan linking section 11D includes a fan control section 11D.
B is the normal fan output adjustment, and as described above, the output f of the air supply fan 3 is changed according to the damper opening adjustment state of each air flow rate changing device 9.
On the other hand, when the setting of the upper limit air volume value qmax is changed by the above upper limit change command, in coordination with this,
Changing the output f of the air supply fan 3 by the number of the variable air volume devices 9 whose setting is to be changed, and the change direction of the upper limit air flow value qmax in the setting change and an increase / decrease amount according to the change amount is used. The fan control unit 11B is forced to execute the normal fan output adjustment based on the adjustment status in preference to the normal fan output adjustment.

That is, when the setting of the upper limit air volume value qmax is changed, the target air flow rate value qs of the air volume changing device 9 that has changed the setting changes due to the change of the air volume adjustment range Zq due to the setting change of the upper limit air volume value qmax. On the other hand, by performing the above forced air supply fan output change, the output f of the air supply fan 3 is changed as compared with the case where the normal fan output adjustment based on the damper opening adjustment state is simply continued. The output value that suits the target air flow rate value qs of each air flow rate changing device 9 later is rapidly changed.
