Description

本発明は、流体搬送設備に関し、さらに詳細には、例えばファンユニットのような流体送出装置から送り出された空気を複数の空気吹出部へ分配し、これら空気吹出部から各対象室に吐出させる際、所定流量に調整された空気を対象室に吹き出させる流体搬送設備に関する。   The present invention relates to a fluid conveyance facility, and more specifically, when air sent from a fluid delivery device such as a fan unit is distributed to a plurality of air blowing units and discharged from the air blowing units to respective target chambers. The present invention relates to a fluid transfer facility that blows out air adjusted to a predetermined flow rate into a target chamber.

流体搬送設備の代表例としては、建造物の各室内などに清浄および/又は温度調整された空気を供給する清浄空気搬送設備や空調設備が知られている。例えば、清浄空気搬送設備では、ファンユニット(流体送出装置)から送給された清浄な空気が主ダクトやこれから分かれた分岐ダクトからなる搬送流路を通り、該搬送流路に設置した可変空気流量調整部(ヴォリュームダンパー)で流量が調整されて吹出口から各対象室に供給される。   As typical examples of the fluid conveyance facility, there are known a clean air conveyance facility and an air conditioning facility that supply clean and / or temperature-adjusted air to each room of a building. For example, in a clean air transfer facility, the clean air supplied from a fan unit (fluid delivery device) passes through a transfer channel consisting of a main duct and a branch duct separated from the main air, and the variable air flow rate installed in the transfer channel The flow rate is adjusted by the adjustment unit (volume damper) and supplied to each target chamber from the blowout port.

従来の流体搬送設備において各ヴォリュームダンパーを通る搬送流体の流量は、直管部やベント部など該流体搬送設備を構成する部材による抵抗、ポンプやファンなどの搬送装置による搬送動力などの要因により大きく変化する。しかし、一般的には、流体送出装置に近いヴォリュームダンパーを通過するときの風量が流体送出装置から遠いヴォリュームダンパーを通過するときの風量より多くなる。そのため、従来の流体搬送設備では、人手により各ヴォリュームダンパーを通過する風量を予め設定された値に近くなるように各ヴォリュームダンパーのダンパー開度を調整している。   The flow rate of the transport fluid passing through each volume damper in a conventional fluid transport facility is large due to factors such as resistance due to members constituting the fluid transport facility such as straight pipes and vents, and transport power by transport devices such as pumps and fans. Change. However, generally, the air volume when passing through a volume damper close to the fluid delivery device is larger than the air volume when passing through a volume damper far from the fluid delivery device. Therefore, in the conventional fluid conveyance equipment, the damper opening of each volume damper is adjusted so that the air volume passing through each volume damper is close to a preset value.

このような制御方法としては、例えば特開平10−63341号公報(特許文献1)に開示されたHIVAC分配システムにおけるブランチ流量の自動較正装置および方法が知られている。前記特許文献1に開示の自動較正装置および方法では、ファンの吹出し口付近のダクトにシステム総流量を検出する流量センサーが設けられ、また各端末ユニットにつながる各ダクトには速度圧センサーが設けられている。この自動較正装置および方法では、オペレータが暖房、換気および空調(HVAC)用流体分配システムの較正を要求すると、各速度圧センサーの較正用データがネットワークを介して遠隔的に集められ、較正計数が算出されてローカルコントローラに送られ、このローカルコントローラによって各端末ユニットが制御され、このプロセス全体がすべて自動的に行われるようにしたものである。   As such a control method, for example, an apparatus and method for automatically calibrating a branch flow rate in a HIVAC distribution system disclosed in JP-A-10-63341 (Patent Document 1) is known. In the automatic calibration apparatus and method disclosed in Patent Document 1, a flow sensor for detecting the total system flow rate is provided in a duct near the fan outlet, and a speed pressure sensor is provided in each duct connected to each terminal unit. ing. In this automatic calibration device and method, when an operator requests calibration of a fluid distribution system for heating, ventilation and air conditioning (HVAC), calibration data for each velocity pressure sensor is collected remotely over the network and a calibration count is obtained. It is calculated and sent to a local controller, and each terminal unit is controlled by the local controller so that the entire process is automatically performed.

特開平10−63341号公報Japanese Patent Laid-Open No. 10-63341

しかし、前記特許文献1に開示された自動較正装置は、流体搬送設備の一部として恒久的に組み込まれているもので、流体搬送設備の作動中はいつでも或いは必要に応じて各ヴォリュームダンパーを通過する風量を制御するものである。そのため、この自動較正装置は、これを組み込んだ流体搬送設備の価格を高めていると共にその設置コストも高価となる。   However, the automatic calibration apparatus disclosed in Patent Document 1 is permanently incorporated as a part of the fluid conveyance facility, and passes through each volume damper whenever the fluid conveyance facility is in operation or as necessary. It controls the amount of air flow. For this reason, the automatic calibration apparatus increases the price of the fluid conveyance equipment incorporating the automatic calibration apparatus and increases the installation cost.

また、通常、新たに建築された建造物に流体搬送設備を設置(施工)したときには、各ヴォリュームダンパーを通過する流体の流量を所定流量に調整するための初期設定が必要となる。しかし、前記特許文献1の自動較正装置では、新たに建築された建造物に設置(施工)した直後に、自動較正装置を働かせない状態で、ある設定条件を満足するように人手により予め高精度に測定を行って流量係数を算出し、その流量係数に基づいて風量の調整を行っておき、その後に条件の変化に応じて較正するようにしたものである。したがって、自動較正装置の有無にかかわらず、施工直後に調整作業が必要となり、この調整作業は手動で行われることになる。   In general, when a fluid transport facility is installed (constructed) in a newly constructed building, initial setting for adjusting the flow rate of the fluid passing through each volume damper to a predetermined flow rate is required. However, in the automatic calibration apparatus of the above-mentioned Patent Document 1, immediately after installation (construction) in a newly constructed building, the automatic calibration apparatus is manually operated in advance so as to satisfy certain setting conditions without operating the automatic calibration apparatus. The flow rate coefficient is calculated by measuring the flow rate, the air volume is adjusted based on the flow rate coefficient, and then calibrated according to the change in the conditions. Therefore, regardless of the presence or absence of the automatic calibration device, adjustment work is required immediately after the construction, and this adjustment work is performed manually.

本発明の目的は、搬送流路に取り外し可能な流量調整装置を仮設し、該流量調整装置により搬送流路を流れる流体の流量を目標流量に自動的に調整することができる流体搬送設備を提供することにある。   An object of the present invention is to provide a fluid conveyance facility in which a removable flow rate adjustment device is temporarily installed in a conveyance channel, and the flow rate of fluid flowing through the conveyance channel can be automatically adjusted to a target flow rate by the flow rate adjustment device.

A flow rate detection device having a sensor, an operation device that is detachably connectable to the operation portion of the flow rate adjusting member, and operates the operation portion, and is installed in the operation device to detect an operation force of the operation portion. An operation force detection device, a storage unit and a calculation unit, and electrically connected to the operation force detection device and the operation device, and inputs the operation force of the operation unit detected by the operation force detection device as a signal. And a control device for outputting an opening / closing amount change value of the opening / closing portion to the operating device, and changing or adjusting the flow rate flowing through the fluid conveyance facility, An adjustment device is attached to the fluid conveyance facility to adjust the flow rate passing through the opening / closing part of each flow rate adjustment member to the target flow rate, and after the adjustment is completed, the flow rate device is removed from the fluid conveyance facility. ,It is in.

本発明の実施態様の一例としては、流量調整ユニットの制御装置における記憶部が、流量調整部材により調整される目標流量、操作部の操作力、及び流量調整部材の流量特性値を記憶する。   As an example of an embodiment of the present invention, the storage unit in the control device of the flow rate adjustment unit stores the target flow rate adjusted by the flow rate adjustment member, the operation force of the operation unit, and the flow rate characteristic value of the flow rate adjustment member.

本発明の実施態様の他の一例としては、演算部が、操作部、操作力検知装置、流量検知装置および記憶部に電気的につながり、開閉部を動かす操作部のための操作要求量を算出する。   As another example of the embodiment of the present invention, the calculation unit is electrically connected to the operation unit, the operation force detection device, the flow rate detection device, and the storage unit, and calculates an operation request amount for the operation unit that moves the opening / closing unit. To do.

本発明における実施態様の他の一例としては、情報処理装置が、流量調整ユニットそれぞれの制御装置から情報を入力し、各流量調整ユニットそれぞれの制御装置に動作指令を出力して、各流量調整部材の開閉部を操作して流量調整部材を通過する流量を目標流量に調整する。   As another example of the embodiment of the present invention, the information processing device inputs information from the control device of each flow rate adjustment unit, outputs an operation command to each control device of each flow rate adjustment unit, and each flow rate adjustment member The flow rate passing through the flow rate adjusting member is adjusted to the target flow rate by operating the opening / closing part.

本発明に係る流体搬送設備によれば、各流量調整部材における目標流量を、この流体搬送設備に対応させた流量調整方法により自動的に調整することができる。すなわち、本発明の流体搬送設備によれば、1つの流量調整部材の流量を、該流量調整部材の開閉部における開度を調整することにより目標流量、即ち所定流量値若しくはその前後の許容範囲内に調整し、かかる調整を順次他の流量調整部材でも行い、全ての前記流量調整部材の流量調整が終った後に検知流量が前記目標流量から外れている前記流量調整部材の有無を判別し、いずれかの前記流量調整部材の流量が前記目標流量から外れている場合には全ての前記流量調整部材の流量調整を規定回数だけ繰り返す、という流量調整方法を実施することにより調整作業が短時間で行え、調整時間の短縮化と調整作業労力の軽減化を図ることができる。   According to the fluid transfer facility according to the present invention, the target flow rate in each flow rate adjusting member can be automatically adjusted by a flow rate adjusting method corresponding to the fluid transfer facility. That is, according to the fluid conveyance facility of the present invention, the flow rate of one flow rate adjustment member is adjusted to the target flow rate, that is, within a predetermined flow rate value or an allowable range before and after the flow rate by adjusting the opening of the flow rate adjustment member. To the other flow rate adjusting member, and after the flow rate adjustment of all the flow rate adjusting members is completed, it is determined whether or not there is the flow rate adjusting member whose detected flow rate is out of the target flow rate.

In addition, it is possible to adjust the opening degree of the opening / closing part in the flow rate adjusting member with high accuracy.

さらに、本発明の流体搬送設備では、情報処理装置が、各流量調整ユニットそれぞれの制御装置から入力された情報を一カ所で管理し、各流量調整ユニットそれぞれの制御装置に動作指令を出力でき、各流量調整ユニットの流量調整部材における開閉部の開度調整操作を情報処理装置により制御できる。そのため流体搬送設備の施工直後に行う各流量調整部材の目標流量調整に多くの作業者がかかわる必要がなくなることから労力の軽減を図ることができると共に、人件費なども大幅に節約できるので調整コストが一層安価となる。   Furthermore, in the fluid conveyance facility of the present invention, the information processing device can manage information input from the control device of each flow rate adjustment unit in one place, and can output an operation command to the control device of each flow rate adjustment unit, The opening / closing adjustment operation of the opening / closing part in the flow rate adjusting member of each flow rate adjusting unit can be controlled by the information processing device. This eliminates the need for many workers to adjust the target flow rate of each flow rate adjustment member that is performed immediately after the construction of the fluid transfer equipment, thus reducing labor and reducing labor costs. Is even cheaper.

As shown in FIG. 4, a flow rate detection device 23 that receives a signal from a flow rate sensor 23a that is detachably installed in the main duct 3 on the downstream side of the first flow rate adjustment member 4A is provided.

また、第1流量調整ユニット21は、第1流量調整部材4Aの操作部13に着脱自在に連結可能な作動装置24を備えている。この作動装置24は、電動モータ(図示せず)、該電動モータの回転力を減速するギヤ機構、該ギヤ機構で減速された回転力を出力する出力軸など(いずれも図示せず)から構成されている。作動装置24は、その出力軸を第1流量調整部材4Aの操作部13における操作軸に着脱可能に連結され、出力軸と操作軸とが連結されているときには電動モータの回転力が減速ギヤ機構から出力軸を介して操作軸に伝達される。したがって、作動装置24が作動されると、操作部13を介して2つの風量調整羽根11a,11bが回転し、それら風量調整羽根11a,11bの開度が調整される。   The first flow rate adjusting unit 21 includes an operating device 24 that can be detachably connected to the operation unit 13 of the first flow rate adjusting member 4A. The actuating device 24 includes an electric motor (not shown), a gear mechanism that reduces the rotational force of the electric motor, an output shaft that outputs the rotational force reduced by the gear mechanism, and the like (all not shown). Has been. The actuating device 24 is detachably connected to the output shaft of the operation unit 13 of the first flow rate adjusting member 4A, and the rotational force of the electric motor reduces the reduction gear mechanism when the output shaft and the operation shaft are connected. To the operation shaft via the output shaft. Therefore, when the operating device 24 is operated, the two air volume adjusting blades 11a and 11b are rotated via the operation unit 13, and the opening degree of the air volume adjusting blades 11a and 11b is adjusted.

作動装置24には、操作部13の操作力と操作量を検知する操作力検知装置25が設置されている。これら作動装置24と操作力検知装置25とは、信号線26a,26bにより制御装置27に電気的に接続されており、該制御装置27は、操作力検知装置25で検知された操作部13の操作力を信号として入力し、かつ作動装置24に対して2つの風量調整羽根11a,11bの開閉量変更値を出力する。   The operation device 24 is provided with an operation force detection device 25 that detects the operation force and the operation amount of the operation unit 13. The actuating device 24 and the operating force detection device 25 are electrically connected to the control device 27 by signal lines 26 a and 26 b, and the control device 27 is connected to the operation unit 13 detected by the operating force detection device 25. The operating force is input as a signal, and the opening / closing amount change values of the two air volume adjusting blades 11a and 11b are output to the actuator 24.

第1流量調整ユニット21の制御装置27は、記憶部(図示せず)と演算部(図示せず)とを備え、記憶部は第1流量調整部材4Aにより調整される目標流量(所定流量値およびその許容範囲)、操作部13の操作量、第1流量調整部材4Aの流量特性、操作部13の操作力と該操作力から割り出した操作量とを記憶する。また、制御装置27に設けられた演算部は、記憶部に電気的につながっており、記憶部に入力されたデータに基づいて風量調整羽根11a,11bを作動させる操作部13に対して操作要求量を算出する。ここで、目標流量即ち「所定流量値およびその許容範囲」とは、所定流量値の前後10%の範囲、好ましくは所定流量値の前後5%の範囲にある状態を言う。例えば、風量調整羽根11a,11bが全開のときに流れる流量を100%とし、ある流量調整部材の所定流量値がその60%であったとすると、測定流量値が50〜70%の範囲にあればよく、更に好ましくは測定流量値が55〜65%の範囲であればよい。   The control device 27 of the first flow rate adjustment unit 21 includes a storage unit (not shown) and a calculation unit (not shown), and the storage unit has a target flow rate (predetermined flow rate value) adjusted by the first flow rate adjustment member 4A. And the allowable range), the operation amount of the operation unit 13, the flow rate characteristics of the first flow rate adjusting member 4A, the operation force of the operation unit 13, and the operation amount calculated from the operation force are stored. Further, the calculation unit provided in the control device 27 is electrically connected to the storage unit, and an operation request is made to the operation unit 13 that operates the air volume adjusting blades 11a and 11b based on the data input to the storage unit. Calculate the amount. Here, the target flow rate, that is, the “predetermined flow rate value and its allowable range” refers to a state that is in the range of 10% before and after the predetermined flow rate value, preferably in the range of 5% before and after the predetermined flow rate value. For example, assuming that the flow rate flowing when the air volume adjustment blades 11a and 11b are fully opened is 100% and the predetermined flow rate value of a certain flow rate adjustment member is 60%, the measured flow rate value is in the range of 50 to 70%. More preferably, the measured flow rate value may be in the range of 55 to 65%.

第1流量調整部材4Aの流量特性とは、図6に示されるように横軸を風量調整羽根11a,11bの開閉値(開度)とし、第1流量調整部材4Aを流れる流量を縦軸としたときのグラフ(特性曲線28)で示されるそれらの相関関係を言う。すなわち、図6の流量特性を示すグラフから明らかなように、風量調整羽根11a,11bの開度がゼロ(全閉)のときには第1流量調整部材4Aを通過する流量はゼロであり、風量調整羽根11a,11bを開きはじめると緩やかに流量が増加する(特性線28の直線部28a)。   As shown in FIG. 6, the flow characteristics of the first flow rate adjusting member 4A are as follows: the horizontal axis is the open / close value (opening) of the air volume adjusting blades 11a and 11b, and the flow rate flowing through the first flow rate adjusting member 4A is the vertical axis. These correlations are shown in the graph (characteristic curve 28). That is, as is apparent from the graph showing the flow rate characteristics of FIG. 6, when the airflow adjustment blades 11a and 11b are open (fully closed), the flow rate passing through the first flow rate adjustment member 4A is zero, and the airflow rate adjustment is performed. When the blades 11a and 11b start to open, the flow rate gradually increases (the straight portion 28a of the characteristic line 28).

開きはじめからある開度になると特性線28は曲線28bを画いて流量が急激に増加し、その後、風量調整羽根11a,11bの開度増加に対応して流量が増加する。このような特性線28において、符号28cで示される範囲が有効制御範囲である。この有効制御範囲を過ぎて、風量調整羽根11a,11bの開度が全開位置に近づくと、特性線28は曲線28dを画いて流量の増加量が急激に減少しはじめ、それを過ぎると緩やかに流量の増加量が減少し(特性線28の直線部28e)、やがて全開位置になって流量は最大となる。   When the opening degree reaches a certain degree of opening, the characteristic line 28 draws a curve 28b, and the flow rate increases rapidly. Thereafter, the flow rate increases corresponding to the opening degree of the air volume adjusting blades 11a, 11b. In such a characteristic line 28, a range indicated by reference numeral 28c is an effective control range. When the opening of the air volume adjusting blades 11a and 11b approaches the fully open position after passing this effective control range, the characteristic line 28 draws a curve 28d, and the increase amount of the flow rate starts to decrease rapidly. The amount of increase in the flow rate decreases (the straight line portion 28e of the characteristic line 28), and eventually the full flow position is reached and the flow rate becomes maximum.

図6に示される流量特性において、直線部28cの範囲が有効制御範囲である、と説明したが、基本的には、風量調整羽根11a,11bの全閉位置と全開位置を除いた範囲でもよい。しかし、全開状態のときの開度を100%としたとき、20%〜80%の範囲を有効制御範囲とすることが好ましい。   In the flow rate characteristics shown in FIG. 6, it has been described that the range of the straight portion 28c is the effective control range, but basically the range except the fully closed position and the fully opened position of the air volume adjusting blades 11a and 11b may be used. . However, it is preferable that the effective control range is 20% to 80% when the opening degree in the fully open state is 100%.

このように構成される流量調整装置20を用いて流体搬送設備1における流量調整方法について以下説明する。流体搬送設備1の各流量調整部材4A〜4Fを通過する流体の流量を流量調整装置20により調整する方法は、図7および図8の各フローチャート図に示す初期設定モードと調整モードとによって構成される。最初に、初期設定モードについて説明すると、該初期設定モードでは、流量調整部材の台数と位置情報を情報処理装置22に入力する(ステップ101)。この実施形態では、流量調整部材は参照符号4A〜4Fで示すように6台である。各流量調整部材4A〜4Fの位置情報としては、流体送出装置2から各流量調整部材4A〜4Fまでの主ダクト又は、主ダクトと分岐ダクトに沿った長さ(道のり)を情報処理装置22に入力する。   A flow rate adjustment method in the fluid conveyance facility 1 using the flow rate adjustment device 20 configured as described above will be described below. The method of adjusting the flow rate of the fluid passing through the flow rate adjusting members 4A to 4F of the fluid transfer facility 1 by the flow rate adjusting device 20 is constituted by the initial setting mode and the adjustment mode shown in the flowcharts of FIGS. The First, the initial setting mode will be described. In the initial setting mode, the number and position information of the flow rate adjusting members are input to the information processing apparatus 22 (step 101). In this embodiment, there are six flow rate adjusting members as indicated by reference numerals 4A to 4F. As the positional information of each flow rate adjusting member 4A to 4F, the length (distance) along the main duct or the main duct and the branch duct from the fluid delivery device 2 to each flow rate adjusting member 4A to 4F is indicated to the information processing device 22. input.

次に、流体送出装置2を停止させるか又は停止状態にあることを確認する(ステップ102)。その後、情報処理装置22からの指示により第1〜6流量調整ユニット21それぞれの作動装置24を作動させ、第1〜第6流量調整部材4A〜4Fそれぞれの操作部13を介して風量調整羽根11a,11bを回転して操作部13の操作力を操作力検知装置25で検知する(ステップ103)。次いで、検知した操作力が著しく高くなる位置についてその操作力を限界操作力とし、その位置をそれぞれ全閉位置と全開位置として認識する(ステップ104)。そして、操作部13の限界操作力と、全閉位置および全開位置から割り出された全閉全開位置間の操作量とが操作特性として制御装置27の記憶部に入力されて保存される(ステップ105)。操作力の検知としては操作部13が風量調整羽根11a,11bを回転させるときの回転トルク値を検出することが望ましい。   Next, it is confirmed that the fluid delivery device 2 is stopped or in a stopped state (step 102). Thereafter, the operating device 24 of each of the first to sixth flow rate adjusting units 21 is operated according to an instruction from the information processing device 22, and the air volume adjusting blade 11a is operated via the operation unit 13 of each of the first to sixth flow rate adjusting members 4A to 4F. , 11b are rotated and the operation force of the operation unit 13 is detected by the operation force detection device 25 (step 103). Next, for the position where the detected operation force becomes extremely high, the operation force is set as the limit operation force, and the positions are recognized as the fully closed position and the fully open position, respectively (step 104). Then, the limit operation force of the operation unit 13 and the operation amount between the fully closed position and the fully open position calculated from the fully closed position and the fully open position are input and stored as operation characteristics in the storage unit of the control device 27 (step). 105). As detection of the operating force, it is desirable to detect the rotational torque value when the operating unit 13 rotates the air volume adjusting blades 11a and 11b.

具体的には、風量調整羽根11a,11bは、全開位置から回転して全閉位置になるとケーシング9の内壁面適所に取り付けられたストッパー15によりそれ以上の回転が阻止されるようになっている。これは、全閉位置から回転して全開位置になったときも同じである。したがって、風量調整羽根11a,11bが全閉位置から回転して全開位置に来たとき、あるいはその逆のときには、風量調整羽根11a,11bはそれ以上回転することができないため操作部13の回転トルク値が増大する。操作力検知装置25は、作動装置24を介して操作部13の回転トルク値を常時検知しており、この回転トルク値が所定値より増大したとき、流量調整部材4A〜4Fの下流側における流量計測値を参考にして全閉位置または全開位置に来たことを判断する。   Specifically, when the air volume adjusting blades 11a and 11b are rotated from the fully opened position to the fully closed position, the air flow adjusting blades 11a and 11b are prevented from further rotation by the stopper 15 attached to a proper position on the inner wall surface of the casing 9. . This is the same when rotating from the fully closed position to the fully open position. Therefore, when the air volume adjusting blades 11a and 11b rotate from the fully closed position to the fully opened position, or vice versa, the air volume adjusting blades 11a and 11b cannot rotate any more, and therefore the rotational torque of the operation unit 13 The value increases. The operating force detection device 25 constantly detects the rotational torque value of the operation unit 13 via the actuating device 24, and when this rotational torque value increases from a predetermined value, the flow rate on the downstream side of the flow rate adjusting members 4A to 4F. Referring to the measured value, it is determined that the fully closed position or fully opened position has been reached.

次に、流量調整部材4A〜4Fのすべてについてステップ103〜105を実施したか否かが判別(ステップ106)され、すべての流量調整部材4A〜4Fについて実施していない場合(NO)にはステップ103の前に戻り、実施されていない流量調整部材について操作特性値を取得する。   Next, it is determined whether or not Steps 103 to 105 have been performed for all of the flow rate adjusting members 4A to 4F (Step 106). If not performed for all of the flow rate adjusting members 4A to 4F (NO), Steps are performed. Returning to 103, an operation characteristic value is acquired for a flow rate adjusting member that is not implemented.

流量調整部材4A〜4Fのすべてについてステップ103〜105を実施している場合(YES)には、ステップ107に移り、情報処理装置22からの指示により、1つの流量調整ユニット21、例えば第1流量調整ユニット21を除く他のすべての流量調整ユニット21において作動装置24により操作部13を動かして流量調整部材4B〜4Fの風量調整羽根11a,11bをほぼ半開(開度約50%)位置にする。次いで、情報処理装置22は、第1流量調整部材4Aの流量特性を測定するため、この流量調整部材4Aに対応する第1流量調整ユニット21の作動装置24により操作部13を動かして風量調整羽根11a,11bを全開位置にする(ステップ108)ように指示をする。その後、流体送出装置2を作動させる(ステップ109)。   When Steps 103 to 105 are performed for all of the flow rate adjusting members 4A to 4F (YES), the process proceeds to Step 107, and one flow rate adjusting unit 21, for example, the first flow rate is received according to an instruction from the information processing device 22. In all other flow rate adjustment units 21 except the adjustment unit 21, the operation unit 13 is moved by the operating device 24 so that the air volume adjustment blades 11a and 11b of the flow rate adjustment members 4B to 4F are substantially half-open (opening degree: about 50%). . Next, in order to measure the flow rate characteristic of the first flow rate adjustment member 4A, the information processing device 22 moves the operation unit 13 by the operating device 24 of the first flow rate adjustment unit 21 corresponding to the flow rate adjustment member 4A, thereby adjusting the air volume adjustment blade. An instruction is made to set 11a and 11b to the fully open position (step 108). Thereafter, the fluid delivery device 2 is operated (step 109).

情報処理装置22は、風量調整羽根11a,11bを全開位置にした第1流量調整部材4Aの操作部13を作動装置24により動かし、風量調整羽根11a,11bを全開位置から全閉位置に回転させ(ステップ110)、これによる第1流量調整部材4Aの下流側での流量変化を流量検知装置23で得て、第1流量調整部材4Aの開度と流量との関係をデータ化し、制御装置27の記憶部に入力する(ステップ111)。制御装置27の記憶部に入力されたこれらデータに基づいて、制御装置27の演算部では、流量変化量/調整羽根開度変化量、の式から第1流量調整部材4Aの流量特性を計算する。すなわち、流量変化量と調整羽根開度変化量とデータに基づき演算部で流量変化特性値(図6の特性線28)が計算され、記憶部に入力されて保存されると共にこの特性値における有効制御範囲(図6参照)が認識されて記憶部に入力される(ステップ112)。   The information processing apparatus 22 moves the operation unit 13 of the first flow rate adjusting member 4A with the air volume adjusting blades 11a and 11b in the fully opened position by the operating device 24, and rotates the air volume adjusting blades 11a and 11b from the fully opened position to the fully closed position. (Step 110), the flow rate change on the downstream side of the first flow rate adjusting member 4A is obtained by the flow rate detecting device 23, and the relationship between the opening degree and the flow rate of the first flow rate adjusting member 4A is converted into data. (Step 111). Based on these data input to the storage unit of the control device 27, the calculation unit of the control device 27 calculates the flow rate characteristic of the first flow rate adjustment member 4A from the equation of flow rate change amount / adjustment blade opening change amount. . That is, the flow rate change characteristic value (characteristic line 28 in FIG. 6) is calculated by the calculation unit based on the flow rate change amount, the adjustment blade opening change amount, and the data, and is input to the storage unit and stored, and is effective in this characteristic value. The control range (see FIG. 6) is recognized and input to the storage unit (step 112).

残るすべての第2〜6流量調整部材4B〜4Fそれぞれについて順次に、第1流量調整部材4Aの流量特性値を得たと同じ方法を繰り返し、即ちステップ110〜ステップ112までの操作を行い、すべての流量調整部材4A〜4Fについて風量調整羽根11a,11bの開度変化量と流量変化量とのデータをそれぞれの制御装置27の記憶部に入力し、そのデータに基づいて流量変化特性値を演算部で計算し、それぞれの特性値における有効制御範囲(図6参照)が認識されて記憶部に入力されて保存される(ステップ113)。その後、すべての流量調整部材4A〜4Fについて流量変化特性値を得たか否かが判別され(ステップ114)、未だ流量変化特性値を得ていない場合(NO)には、流量変化特性値を得ていない流量調整部材についてステップ110〜112を繰り返す。すべての流量調整部材4A〜4Fについて流量特性値を得ている場合(YES)には、これらすべての流量調整部材4A〜4Fについて風量調整羽根11a,11bを回転させてほぼ半開位置にする(ステップ115)。   For each of the remaining second to sixth flow rate adjusting members 4B to 4F, the same method as that for obtaining the flow rate characteristic value of the first flow rate adjusting member 4A is repeated in sequence, that is, the operations from step 110 to step 112 are performed. The flow rate adjustment members 4A to 4F are inputted with data of the opening change amount and the flow rate change amount of the air volume adjusting blades 11a and 11b to the storage units of the respective control devices 27, and the flow rate change characteristic value is calculated based on the data. The effective control range (see FIG. 6) in each characteristic value is recognized, input to the storage unit, and stored (step 113). Thereafter, it is determined whether or not the flow rate change characteristic values have been obtained for all the flow rate adjusting members 4A to 4F (step 114). If the flow rate change characteristic values have not been obtained yet (NO), the flow rate change characteristic values are obtained. Steps 110 to 112 are repeated for the flow rate adjusting member that is not. When the flow rate characteristic values are obtained for all the flow rate adjusting members 4A to 4F (YES), the air flow rate adjusting blades 11a and 11b are rotated for all the flow rate adjusting members 4A to 4F to almost the half open position (step) 115).

以上のようにして空調設備の流体搬送設備1における第1〜6流量調整部材4A〜4Fについて流量変化特性値など必要なデータがそれぞれ対応する流量調整ユニット21により得られたところで、この初期設定モ−ドが終了する。   As described above, when necessary data such as flow rate change characteristic values are obtained by the corresponding flow rate adjustment units 21 for the first to sixth flow rate adjustment members 4A to 4F in the fluid transfer facility 1 of the air conditioning facility, this initial setting mode is set. -The process ends.

流量調整装置20の初期設定モ−ドが終了すると、各ダクトから第1〜4対象室5A〜5Dに吐出される流体の流量や、主ダクト3及び分岐ダクト6内の流量を目標流量に調整する調整モ−ドが実行される。この調整モードは、以下に説明する手順で行われる。この調整モードを示すフローチャート図は、図8と図9とに分けて示されており、図9のフローチャート図は図8に示されるフローチャート図の続きである。これらフローチャート図に示されるように、情報処理装置22からの指示によりすべての流量調整ユニット21における作動装置24が動かされ、操作部13を介して各流量調整部材4A〜4Fの風量調整羽根11a,11bを同じ開度にする(ステップ201)。   When the initial setting mode of the flow rate adjusting device 20 is completed, the flow rate of the fluid discharged from each duct to the first to fourth target chambers 5A to 5D and the flow rates in the main duct 3 and the branch duct 6 are adjusted to the target flow rate. The adjustment mode to be executed is executed. This adjustment mode is performed according to the procedure described below. The flowchart showing this adjustment mode is divided into FIG. 8 and FIG. 9, and the flowchart of FIG. 9 is a continuation of the flowchart shown in FIG. As shown in these flowcharts, the operation devices 24 in all the flow rate adjustment units 21 are moved by an instruction from the information processing device 22, and the air volume adjustment blades 11 a of the flow rate adjustment members 4 </ b> A to 4 </ b> F are operated via the operation unit 13. 11b is set to the same opening degree (step 201).

次に、流体送出装置2の電源を入れて作動させ(ステップ202)、各流量調整ユニット21の流量検知装置23でそれぞれ流量調整部材4A〜4Fの下流側の流量を検知し、その計測データを制御装置27に入力する(ステップ203)。各流量調整ユニット21の制御装置27には、それぞれ対応する流量調整部材4A〜4Fを通過すべき流体の流量値が目標流量として予め入力されている。それぞれの流量調整ユニット21の制御装置27は、対応する流量調整部材4A〜4Fについての目標流量とステップ203で得た計測流量値(検知流量)とを比較し、その差を情報処理装置22に入力する(ステップ204)。   Next, the fluid delivery device 2 is turned on and operated (step 202), the flow rate detection device 23 of each flow rate adjustment unit 21 detects the flow rate downstream of the flow rate adjustment members 4A to 4F, and the measurement data is obtained. Input to the control device 27 (step 203). The flow rate value of the fluid that should pass through the corresponding flow rate adjusting members 4A to 4F is input in advance to the control device 27 of each flow rate adjusting unit 21 as the target flow rate. The control device 27 of each flow rate adjusting unit 21 compares the target flow rate for the corresponding flow rate adjusting members 4A to 4F with the measured flow rate value (detected flow rate) obtained in step 203, and the difference is transferred to the information processing device 22. Input (step 204).

次いで、流体送出装置2に最も近い第1流量調整部材4Aの開度を調整するため情報処理装置22から第1流量調整ユニット21の制御装置27に指示が出力される。制御装置27はこの指示を受けて作動装置24を動かし、操作部13を介して第1流量調整部材4Aの風量調整羽根11a,11bを回転させる。その際、風量調整羽根11a,11bの開度調整は、図6の特性線28における有効制御範囲(線部分28cの範囲)内でなされる。風量調整羽根11a,11bの開度が変化している間の流量変化値は、制御装置27により目標流量と比較される(ステップ205)。   Next, an instruction is output from the information processing device 22 to the control device 27 of the first flow rate adjustment unit 21 in order to adjust the opening degree of the first flow rate adjustment member 4A closest to the fluid delivery device 2. In response to this instruction, the control device 27 moves the operating device 24 to rotate the air volume adjusting blades 11a and 11b of the first flow rate adjusting member 4A via the operation unit 13. At that time, the opening adjustment of the air volume adjusting blades 11a and 11b is performed within the effective control range (the range of the line portion 28c) in the characteristic line 28 of FIG. The flow rate change value while the opening degree of the air volume adjusting blades 11a and 11b is changed is compared with the target flow rate by the control device 27 (step 205).

制御装置27が風量調整羽根11a,11bの開度変化に伴う流量の変化値と目標流量とを比較しながら、計測流量が目標流量になるかならないか、即ち所定流量値か又はその許容範囲に入るか否かを判別し(ステップ206)、計測流量が目標流量にならない限りステップ205の直前に戻って風量調整羽根11a,11bの開度が変化され続ける。計測流量が目標流量になると、制御装置27は作動装置24を停止して風量調整羽根11a,11bの回転を停止する。これにより、とりあえず第1流量調整部材4Aの開度調整が終了する。   While the control device 27 compares the change value of the flow rate according to the change in the opening of the air volume adjusting blades 11a and 11b with the target flow rate, whether the measured flow rate becomes the target flow rate, that is, the predetermined flow rate value or its allowable range. Whether or not the air flow enters is determined (step 206), and unless the measured flow rate reaches the target flow rate, the flow returns to immediately before step 205 and the openings of the air volume adjusting blades 11a and 11b are continuously changed. When the measured flow rate reaches the target flow rate, the control device 27 stops the operation device 24 and stops the rotation of the air volume adjusting blades 11a and 11b. Thereby, the opening degree adjustment of the first flow rate adjusting member 4A is ended for the time being.

その後、流体送出装置2に次に近い第2流量調整部材4Bの開度を調整するため情報処理装置22から第2流量調整ユニット21の制御装置27に指示が出力される。制御装置27がこの指示を受けると、先に説明した第1流量調整部材4Aの開度調整の場合と同様なステップで第1流量調整部材4Aの開度を調整する。この時も、風量調整羽根11a,11bの開度が変化している間の流量変化値は、制御装置27により第2流量調整部材4Bにおける目標流量と比較される(ステップ207)。   Thereafter, an instruction is output from the information processing device 22 to the control device 27 of the second flow rate adjustment unit 21 in order to adjust the opening degree of the second flow rate adjustment member 4B next to the fluid delivery device 2. When the control device 27 receives this instruction, the opening degree of the first flow rate adjusting member 4A is adjusted in the same steps as the opening degree adjustment of the first flow rate adjusting member 4A described above. Also at this time, the flow rate change value while the opening degree of the air volume adjusting blades 11a and 11b is changed is compared with the target flow rate in the second flow rate adjusting member 4B by the control device 27 (step 207).

制御装置27は風量調整羽根11a,11bの開度変化に伴う流量の変化値と目標流量とを比較しながら、計測流量が目標流量なったか否かを判別し(ステップ208)、計測流量が目標流量にならない限りステップ207の直前に戻って風量調整羽根11a,11bの開度が変化され続ける。計測流量が目標流量になると、制御装置27は作動装置24を停止して風量調整羽根11a,11bの回転を停止する。これにより、とりあえず第2流量調整部材4Bの開度調整が終了する。しかし、第2流量調整部材4Bの流量を目標流量に調整したとき、既に調整した第1流量調整部材4Aの流量値に影響を及ぼして、その流量値が目標流量から外れてしまうことがある。   The control device 27 determines whether or not the measured flow rate becomes the target flow rate while comparing the change value of the flow rate associated with the change in the opening of the air volume adjusting blades 11a and 11b with the target flow rate (step 208), and the measured flow rate is the target flow rate. As long as the flow rate is not reached, the flow returns to immediately before step 207 and the opening degree of the air volume adjusting blades 11a and 11b is continuously changed. When the measured flow rate reaches the target flow rate, the control device 27 stops the operation device 24 and stops the rotation of the air volume adjusting blades 11a and 11b. Thereby, the opening degree adjustment of the second flow rate adjusting member 4B is ended for the time being. However, when the flow rate of the second flow rate adjustment member 4B is adjusted to the target flow rate, the flow rate value of the first flow rate adjustment member 4A that has already been adjusted is affected, and the flow rate value may deviate from the target flow rate.

そこで、風量調整羽根11a,11bの開度調整により第2流量調整部材4Bを通る流体の流量を目標流量に調整し終わったときには、既に調整済の第1流量調整部材4Aを通る流体の流量(目標流量)に変化がないかを判別する(ステップ209)。このステップ209で、第1流量調整部材4Aの流量が目標流量から外れている(変化がある)、と判別(NO)された場合には、ステップ205の直前に戻って第1流量調整部材4Aの流量を再調整し、引き続き第2流量調整部材4Bの流量を再調整する。ステップ209で、第1流量調整部材4Aの流量が目標流量から外れていない(変化がない)、と判別(YES)された場合には、次に流体送出装置2に近い第5流量調整部材4Eの流量を調整するステップ210に移行する。   Therefore, when the flow rate of the fluid passing through the second flow rate adjusting member 4B is adjusted to the target flow rate by adjusting the opening of the air volume adjusting blades 11a and 11b, the flow rate of the fluid passing through the already adjusted first flow rate adjusting member 4A ( It is determined whether there is any change in the target flow rate (step 209). In this step 209, if it is determined (NO) that the flow rate of the first flow rate adjusting member 4A is deviated from the target flow rate (there is a change), the process returns to step 205 and returns to the first flow rate adjusting member 4A. The flow rate of the second flow rate adjustment member 4B is readjusted. If it is determined in step 209 that the flow rate of the first flow rate adjustment member 4A is not deviated from the target flow rate (no change) (YES), the fifth flow rate adjustment member 4E next to the fluid delivery device 2 is determined. The process proceeds to step 210 for adjusting the flow rate of.

このステップ210では、ステップ207と同じように第5流量調整部材4Eの流量を調整しながら、該第5流量調整部材4Eの流量が目標流量になったか否かを判別し(ステップ211)、目標流量にならない(NO)場合にはステップ210の直前に戻って第5流量調整部材4Eの流量調整を繰り返し、目標流量になった(YES)場合には、既に調整済の第1,2流量調整部材4A,4Bの流量値に変化がないかを判別する(ステップ212)。   In step 210, the flow rate of the fifth flow rate adjusting member 4E is adjusted in the same manner as in step 207, and it is determined whether or not the flow rate of the fifth flow rate adjusting member 4E has reached the target flow rate (step 211). If the flow rate does not reach (NO), the flow returns to immediately before step 210 and the flow rate adjustment of the fifth flow rate adjusting member 4E is repeated. If the target flow rate is reached (YES), the already adjusted first and second flow rate adjustments are performed. It is determined whether there is any change in the flow rate values of the members 4A and 4B (step 212).

ステップ212で、第1,2流量調整部材4A,4Bの流量がそれぞれの目標流量から外れている(変化がある)、と判別(NO)された場合には、ステップ205の直前に戻って第1流量調整部材4Aの流量を再調整し、引き続き第2流量調整部材4Bおよび第5流量調整部材4Eの流量を再調整する。また、ステップ212で第2流量調整部材4Bの流量だけが目標流量から外れている(変化がある)、と判別(NO)された場合には、ステップ207の直前に戻って第2流量調整部材4Bの流量を再調整する。ステップ212で、第1,2流量調整部材4A,4Bいずれの流量もそれぞれの目標流量から外れていない(変化がない)、と判別(YES)された場合には、次に流体送給装置2に近い第6流量調整部材4Fの流量を調整するためステップ213に移行する。   If it is determined in step 212 that the flow rates of the first and second flow rate adjusting members 4A and 4B are out of the target flow rates (there is a change) (NO), the process returns to step 205 and returns to the first. The flow rate of the first flow rate adjustment member 4A is readjusted, and then the flow rates of the second flow rate adjustment member 4B and the fifth flow rate adjustment member 4E are readjusted. If it is determined in step 212 that only the flow rate of the second flow rate adjusting member 4B is out of the target flow rate (changed) (NO), the process returns to step 207 and returns to the second flow rate adjusting member. Readjust the flow rate of 4B. If it is determined in step 212 that the flow rates of the first and second flow rate adjusting members 4A and 4B are not deviated from the respective target flow rates (no change) (YES), the fluid feeder 2 is next moved. In order to adjust the flow rate of the sixth flow rate adjusting member 4F close to, the process proceeds to step 213.

ステップ213では、先に説明した第1流量調整部材4Aの開度調整の場合と同様なステップで第6流量調整部材4Fの開度が調整され、風量調整羽根11a,11bの開度が変化している間の流量変化値は、制御装置27により第6流量調整部材4Fの目標流量と比較される。制御装置27は風量調整羽根11a,11bの開度変化に伴う流量の変化値と目標流量とを比較しながら、計測流量が目標流量になるか否かを判別し(ステップ214)、計測流量が目標流量にならない限りステップ213の直前に戻って風量調整羽根11a,11bの開度が変化され続ける。計測流量が目標流量になると、とりあえず第6流量調整部材4Fの開度調整が終了する。しかし、第6流量調整部材4Fの流量を目標流量に調整したとき、既に調整した第1、2,5流量調整部材4A,4B,4Eの流量値に影響を及ぼして、それらの流量値がそれぞれの目標流量から外れてしまうことがある。その場合は、そのうちの最先に調整された流量調整部材の調整ステップの直前に戻り、それ以降の流量調整部材について再調整される。   In step 213, the opening degree of the sixth flow rate adjustment member 4F is adjusted in the same step as the opening degree adjustment of the first flow rate adjustment member 4A described above, and the opening degree of the air volume adjustment blades 11a and 11b changes. During this time, the flow rate change value is compared with the target flow rate of the sixth flow rate adjusting member 4F by the control device 27. The control device 27 determines whether or not the measured flow rate becomes the target flow rate while comparing the change value of the flow rate associated with the change in opening of the air volume adjusting blades 11a and 11b with the target flow rate (step 214). As long as the target flow rate is not reached, the opening of the air volume adjusting blades 11a and 11b continues to change immediately before step 213. When the measured flow rate becomes the target flow rate, the opening degree adjustment of the sixth flow rate adjusting member 4F is ended for the time being. However, when the flow rate of the sixth flow rate adjustment member 4F is adjusted to the target flow rate, the flow rate values of the first, second, and fifth flow rate adjustment members 4A, 4B, and 4E that have already been adjusted are affected. May be out of the target flow rate. In this case, the flow returns to the step immediately before the adjustment step of the flow rate adjustment member adjusted first, and the flow rate adjustment members thereafter are readjusted.

すなわち、風量調整羽根11a,11bの開度調整により該第6流量調整部材4Fを通る流体の流量を目標流量に調整し終わったときには、既に調整済の第1,2,5流量調整部材4A,4B,4Eを通る流体の流量(目標流量)に変化がないかを判別する(ステップ215)。このステップ215で、第1、2,5流量調整部材4A,4B,4Eの流量がそれぞれの目標流量から外れている(変化がある)、と判別(NO)された場合には、ステップ205の直前に戻って第1,2,5,6流量調整部材4A,4B,4E,4Fにおける流量の再調整が順次実行される。   That is, when the flow rate of the fluid passing through the sixth flow rate adjusting member 4F is adjusted to the target flow rate by adjusting the opening degree of the air volume adjusting blades 11a, 11b, the already adjusted first, second, fifth flow rate adjusting members 4A, It is determined whether there is any change in the flow rate (target flow rate) of the fluid passing through 4B and 4E (step 215). If it is determined (NO) in step 215 that the flow rates of the first, second, and fifth flow rate adjusting members 4A, 4B, and 4E are out of the target flow rates (changes exist), step 205 Returning immediately before, the readjustment of the flow rate in the first, second, fifth, and sixth flow rate adjusting members 4A, 4B, 4E, and 4F is sequentially executed.

また、これら第1、2,5流量調整部材4A,4B,4Eのいずれか1つ或いは2つの流量調整部材における流量がそれぞれの目標流量から外れている(変化がある)、と判別された場合には、そのうちの最先に調整された流量調整部材の調整ステップの直前に戻り、それ以降の流量調整部材について再調整される。ステップ215で、これら第1,2,5流量調整部材4A,4B,4Eの流量がそれぞれの目標流量から外れていない(変化がない)、と判別(YES)された場合には、次に流体送出装置2に近い第3流量調整部材4Cの流量を調整するステップ216に移行する。   Further, when it is determined that the flow rate in any one or two of the first, second, fifth flow rate adjusting members 4A, 4B, 4E deviates (changes) from the respective target flow rate. In this case, the flow returns to the position immediately before the adjustment step of the flow rate adjustment member adjusted first, and the flow rate adjustment members thereafter are readjusted. If it is determined in step 215 that the flow rates of the first, second, and fifth flow rate adjusting members 4A, 4B, and 4E do not deviate from each target flow rate (no change) (YES), then the fluid The process proceeds to step 216 for adjusting the flow rate of the third flow rate adjusting member 4C close to the delivery device 2.

ステップ216では、先に説明した第1流量調整部材4Aの開度調整の場合と同様なステップで第3流量調整部材4Cの開度が調整され、風量調整羽根11a,11bの開度が変化している間の流量変化値は、制御装置27により第3流量調整部材4Cの目標流量と比較される。制御装置27は風量調整羽根11a,11bの開度変化に伴う流量の変化値と目標流量とを比較しながら、計測流量が目標流量になるか否かを判別し(ステップ217)、計測流量が目標流量にならない限りステップ216の直前に戻って風量調整羽根11a,11bの開度が変化され続ける。計測流量が目標流量になると、とりあえず第3流量調整部材4Cの開度調整が終了する。しかし、第3流量調整部材4Cの流量を目標流量に調整したとき、既に調整した第1,2,5,6流量調整部材4A,4B,4E,4Fの流量値に影響を及ぼして、それらの流量値がそれぞれの目標流量から外れてしまうことがある。その場合は、そのうちの最先に調整された流量調整部材の調整ステップの直前に戻り、それ以降の流量調整部材について再調整される。   In step 216, the opening degree of the third flow rate adjusting member 4C is adjusted in the same step as the opening degree adjustment of the first flow rate adjusting member 4A described above, and the opening degree of the air volume adjusting blades 11a and 11b is changed. During this time, the flow rate change value is compared with the target flow rate of the third flow rate adjusting member 4C by the control device 27. The control device 27 determines whether or not the measured flow rate becomes the target flow rate while comparing the change value of the flow rate accompanying the change in opening of the air volume adjusting blades 11a and 11b with the target flow rate (step 217). As long as the target flow rate is not reached, the opening degree of the air volume adjusting blades 11a and 11b continues to change immediately before step 216. When the measured flow rate becomes the target flow rate, the opening degree adjustment of the third flow rate adjusting member 4C is ended for the time being. However, when the flow rate of the third flow rate adjustment member 4C is adjusted to the target flow rate, the flow rate values of the already adjusted first, second, fifth, and sixth flow rate adjustment members 4A, 4B, 4E, and 4F are affected. The flow rate value may deviate from the respective target flow rate. In this case, the flow returns to the step immediately before the adjustment step of the flow rate adjustment member adjusted first, and the flow rate adjustment members thereafter are readjusted.

すなわち、風量調整羽根11a,11bの開度調整により第3流量調整部材4Cを通る流体の流量を目標流量に調整し終わったときには、既に調整済の第1,2,5,6流量調整部材4A,4B,4E,4Fそれぞれの流量(目標流量)に変化がないかを判別する(ステップ218)。このステップ218で、第1、2,5,6流量調整部材4A,4B,4E,4Fの流量がそれぞれの目標流量から外れている(変化がある)、と判別(NO)された場合には、ステップ205の直前に戻って第1,2,5,6,3流量調整部材4A,4B,4E,4F,4Cにおける流量の再調整が順次実行される。   That is, when the flow rate of the fluid passing through the third flow rate adjusting member 4C is adjusted to the target flow rate by adjusting the opening of the air volume adjusting blades 11a and 11b, the already adjusted first, second, fifth, and sixth flow rate adjusting members 4A. , 4B, 4E, 4F is determined whether there is any change in the flow rate (target flow rate) (step 218). If it is determined in step 218 that the flow rates of the first, second, fifth, and sixth flow rate adjusting members 4A, 4B, 4E, and 4F are out of their target flow rates (there is a change) (NO) , The flow rate adjustment in the first, second, fifth, sixth, and third flow rate adjusting members 4A, 4B, 4E, 4F, and 4C is sequentially executed immediately before step 205.

また、これら第1、2,5,6流量調整部材4A,4B,4E,4Fのいずれか1つ或いは3つの流量調整部材における流量が、対応する目標流量から外れている(変化がある)、と判別された場合には、そのうちの最先に調整された流量調整部材の調整ステップの直前に戻り、それ以降の流量調整部材について再調整される。ステップ218で、これら第1,2,5,6流量調整部材4A,4B,4E,4Fの流量が目標流量から外れていない(変化がない)、と判別(YES)された場合には、流体送出装置2から最も遠い位置にある第4流量調整部材4Dの流量を調整するステップ219に移行する。   Further, the flow rate in any one or three of the first, second, fifth, sixth flow rate adjusting members 4A, 4B, 4E, 4F is out of the corresponding target flow rate (there is a change), Is determined, the flow returns to the position immediately before the adjustment step of the flow adjustment member adjusted first, and the flow adjustment members thereafter are readjusted. If it is determined in step 218 that the flow rates of the first, second, fifth, and sixth flow rate adjusting members 4A, 4B, 4E, and 4F are not deviated from the target flow rate (no change) (YES) The process proceeds to step 219 in which the flow rate of the fourth flow rate adjusting member 4D located farthest from the delivery device 2 is adjusted.

ステップ219では、先に説明した第1流量調整部材4Aの開度調整の場合と同様なステップで最後の第4流量調整部材4Dの開度が調整され、制御装置27により第4流量調整部材4Dの目標流量と計測流量値とが比較される。制御装置27は風量調整羽根11a,11bの開度変化に伴う流量の変化値と目標流量とを比較しながら、計測流量が目標流量になっているか否かを判別し(ステップ220)、計測流量値が目標流量にならない限りステップ220の直前に戻って風量調整羽根11a,11bの開度が変化され続ける。計測流量値が目標流量になると、とりあえず第4流量調整部材4Dの開度調整が終了する。しかし、第4流量調整部材4Dの流量を目標流量に調整したとき、既に調整した第1,2,5,6,3流量調整部材4A,4B,4E,4F,4Cの流量値に影響を及ぼして、それらの流量値がそれぞれの目標流量から外れてしまうことがある。その場合は、そのうちの最先に調整された流量調整部材の調整ステップの直前に戻り、それ以降の流量調整部材について再調整される。   In step 219, the opening degree of the last fourth flow rate adjusting member 4D is adjusted in the same step as the opening degree adjustment of the first flow rate adjusting member 4A described above, and the fourth flow rate adjusting member 4D is controlled by the control device 27. The target flow rate and the measured flow rate value are compared. The control device 27 determines whether or not the measured flow rate is the target flow rate by comparing the change value of the flow rate associated with the change in the opening of the air volume adjusting blades 11a and 11b with the target flow rate (step 220). As long as the value does not reach the target flow rate, the flow returns to immediately before step 220 and the opening degree of the air volume adjusting blades 11a and 11b is continuously changed. When the measured flow rate value becomes the target flow rate, the opening degree adjustment of the fourth flow rate adjusting member 4D is ended for the time being. However, when the flow rate of the fourth flow rate adjustment member 4D is adjusted to the target flow rate, the flow rate values of the already adjusted first, second, fifth, sixth, and third flow rate adjustment members 4A, 4B, 4E, 4F, and 4C are affected. As a result, these flow rates may deviate from their respective target flow rates. In this case, the flow returns to the step immediately before the adjustment step of the flow rate adjustment member adjusted first, and the flow rate adjustment members thereafter are readjusted.

すなわち、風量調整羽根11a,11bの開度調整により第4流量調整部材4Dを通る流体の流量を目標流量に調整し終わったときには、既に調整済の第1,2,5,6,3流量調整部材4A,4B,4E,4F,4Cそれぞれの流量(目標流量)に変化がないかを判別する(ステップ221)。このステップ221で、第1、2,5,6,3流量調整部材4A,4B,4E,4F,4Cの流量がそれぞれの目標流量から外れている(変化がある)、と判別(NO)された場合には、ステップ205の直前に戻って第1,2,5,6,3,4流量調整部材4A,4B,4E,4F,4C,4Dにおける流量の再調整が順次実行される。   That is, when the flow rate of the fluid passing through the fourth flow rate adjusting member 4D is adjusted to the target flow rate by adjusting the opening of the air volume adjusting blades 11a and 11b, the already adjusted first, second, fifth, sixth, and third flow rate adjustments are performed. It is determined whether or not the flow rate (target flow rate) of each of the members 4A, 4B, 4E, 4F, and 4C has changed (step 221). In this step 221, it is determined (NO) that the flow rates of the first, second, fifth, sixth, and third flow rate adjusting members 4A, 4B, 4E, 4F, and 4C are deviated (changed) from the respective target flow rates. In this case, the flow returns to immediately before step 205, and the readjustment of the flow rate in the first, second, fifth, sixth, third, and fourth flow rate adjustment members 4A, 4B, 4E, 4F, 4C, and 4D is sequentially executed.

また、これら第1、2,5,6,3流量調整部材4A,4B,4E,4F,4Cのいずれか1つ或いは4つの流量調整部材における流量が、対応する目標流量から外れている(変化がある)、と判別された場合には、そのうちの最先に調整された流量調整部材の調整ステップの直前に戻り、それ以降の流量調整部材について再調整される。ステップ221で、これら第1,2,5,6,3流量調整部材4A,4B,4E,4F,4Cの流量がそれぞれの目標流量から外れていない(変化がない)、と判別(YES)された場合には、この調整モードが終了する。   In addition, the flow rate in any one or four of the first, second, fifth, sixth, and third flow rate adjusting members 4A, 4B, 4E, 4F, and 4C deviates from the corresponding target flow rate (changes). ), The flow returns to immediately before the adjustment step of the flow adjustment member adjusted first, and the flow adjustment members thereafter are readjusted. In step 221, it is determined (YES) that the flow rates of the first, second, fifth, sixth, and third flow rate adjusting members 4A, 4B, 4E, 4F, and 4C are not deviated from the respective target flow rates (no change). If this happens, this adjustment mode ends.

このモードの終了により、すべての流量調整部材4A〜4Fが流量制御装置20によって目標流量に調整されると、情報処理装置22におけるディスプレイなどに、第1〜6流量調整部材4A〜4Fについて設計条件が満たされた旨の表示が出て、ユーザー又は管理者に知らせる。調整モ−ドが終了して第1〜6流量調整部材4A〜4Fについて設計条件が満たされた場合、情報処理装置22のディスプレイにそのことが表示されるだけではなく音声などによって操作者に知らせるようにすることもできる。   When all of the flow rate adjustment members 4A to 4F are adjusted to the target flow rate by the flow rate control device 20 by the end of this mode, the design conditions for the first to sixth flow rate adjustment members 4A to 4F are displayed on the display or the like in the information processing device 22. A message to the effect that the above is satisfied is displayed to inform the user or administrator. When the adjustment mode is completed and the design conditions for the first to sixth flow rate adjusting members 4A to 4F are satisfied, the fact is not only displayed on the display of the information processing apparatus 22, but the operator is notified by voice or the like. It can also be done.

ところで、図8及び図9に示されるフローチャート図に基づく一連の流量調整を流量調整装置20によって行っているときに、第1〜6流量調整部材4A〜6Fいずれかの流量が所定回数だけ実行しても設計条件を満足しない(目標流量にならない)場合には、設計条件が満足されない流量調整部材を情報処理装置22のディスプレイに表示させ、その調整を一時的に保留し、他の流量調整部材について流量調整を行う。   Incidentally, when a series of flow rate adjustments based on the flowcharts shown in FIGS. 8 and 9 are performed by the flow rate adjustment device 20, the flow rate of any of the first to sixth flow rate adjustment members 4A to 6F is executed a predetermined number of times. However, if the design condition is not satisfied (the target flow rate is not reached), the flow rate adjusting member that does not satisfy the design condition is displayed on the display of the information processing apparatus 22, the adjustment is temporarily suspended, and another flow rate adjusting member is displayed. Adjust the flow rate for.

設計条件が満足されずに一時的に保留された流量調整部材については、それ以外の流量調整部材の流量調整が終了した後に再度調整が実行される。しかし、再度の調整でも目標流量にならない場合には、風量調整羽根11a,11bを全開に設定するか、或いはこの流体搬送設備のユーザー又は管理者が望む任意の開度に手動で設定する。その際、既にそれぞれの目標流量に調整されている他の流量調整部材の流量に影響を及ぼしてその流量値がそれぞれの目標流量から外れてしまう場合には、目標流量から外れた流量調整部材の流量調整を再度行う。その時、目標流量から外れた流量調整部材の流量が目標流量になればそれで終了し、もし、目標流量にならなければ目標流量に最も近い流量値に設定して終了する。   For the flow rate adjustment member that is temporarily suspended without satisfying the design condition, the adjustment is performed again after the flow rate adjustment of the other flow rate adjustment members is completed. However, if the target flow rate is not reached even after re-adjustment, the air volume adjusting blades 11a and 11b are set to fully open, or manually set to an arbitrary opening desired by the user or administrator of the fluid conveyance equipment. At this time, if the flow rate value of other flow rate adjustment members already adjusted to the respective target flow rates is affected and the flow rate values deviate from the respective target flow rates, the flow rate adjustment members that are out of the target flow rate Adjust the flow rate again. At this time, if the flow rate of the flow rate adjusting member deviating from the target flow rate reaches the target flow rate, the flow ends. If not, the flow rate value closest to the target flow rate is set and the flow ends.

図8及び図9に示したフローチャート図による調整モードは、各流量調整部材4A〜4Fを通過する流体の流量を流体送出装置2に近い順からそれぞれ目標流量に設定する調整方法であったが、この調整モードでは、後から調整した流量調整部材によって既に調整が終了した流量調整部材に影響を与える場合、既に調整が終了した流量調整部材を再調整する必要があり、この再調整が繰り返し起こることから調整に時間が掛かる、という問題がある。   The adjustment mode according to the flowcharts shown in FIGS. 8 and 9 is an adjustment method in which the flow rate of the fluid passing through each of the flow rate adjustment members 4A to 4F is set to the target flow rate from the order close to the fluid delivery device 2, respectively. In this adjustment mode, if the flow adjustment member that has already been adjusted is affected by the flow adjustment member that has been adjusted later, it is necessary to readjust the flow adjustment member that has already been adjusted, and this readjustment will occur repeatedly. There is a problem that it takes time to adjust.

図10は、本発明の流体搬送設備1を構成している流量調整装置20の他の流量調整方法における調整モードを示すフローチャート図である。図10のフローチャート図に示されている調整モードによると、各流量調整部材4A〜4Fの流量調整を短時間で行うことができる。以下、図10のフローチャート図に沿ってこの調整モードを説明する。この流量調整方法における初期設定モードは、図7のフローチャート図と同じであるので、その説明を省略する。   FIG. 10 is a flowchart showing an adjustment mode in another flow rate adjustment method of the flow rate adjustment device 20 constituting the fluid conveyance facility 1 of the present invention. According to the adjustment mode shown in the flowchart of FIG. 10, the flow rate adjustment of each of the flow rate adjustment members 4A to 4F can be performed in a short time. Hereinafter, this adjustment mode will be described with reference to the flowchart of FIG. Since the initial setting mode in this flow rate adjustment method is the same as that in the flowchart of FIG. 7, the description thereof is omitted.

図10のフローチャート図に示す調整モードでは、最初に、すべての流量調整部材4A〜4Fの風量調整羽根11a,11bを回転させて半開にする。風量調整羽根11a,11bの開度を半開にする理由は、調整前の風量調整羽根11a,11bを半開にしておくと、その後の調整で風量調整羽根11a,11bを大きく回転する必要がないからである。この利点を考慮しなければ、風量調整羽根11a,11bの開度は全閉以外の任意の開度でよい(ステップ301)。図7のフローチャート図に示す初期設定モードでは、ステップ115で各流量調整部材4A〜4Fにおける風量調整羽根11a,11bの開度をほぼ半開にして終了しているので、このステップ301では、すべての流量調整部材4A〜4Fにおける風量調整羽根11a,11bの開度がほぼ半開に設定されているか否かの確認と、ユーザー又は管理者が流量調整部材4A〜4Fにおける風量調整羽根11a,11bの開度を指定している場合にその開度への設定とを行うことになる。   In the adjustment mode shown in the flowchart of FIG. 10, first, the air volume adjusting blades 11a and 11b of all the flow rate adjusting members 4A to 4F are rotated to be half open. The reason why the airflow adjustment blades 11a and 11b are opened halfway is that if the airflow adjustment blades 11a and 11b before adjustment are half-opened, it is not necessary to rotate the airflow adjustment blades 11a and 11b greatly in the subsequent adjustment. It is. If this advantage is not taken into account, the opening degree of the air volume adjusting blades 11a and 11b may be an arbitrary opening degree other than full closing (step 301). In the initial setting mode shown in the flowchart of FIG. 7, since the opening of the air volume adjusting blades 11a and 11b in the flow rate adjusting members 4A to 4F is almost half open in step 115, the process is finished in step 301. Confirming whether or not the opening degree of the air volume adjusting blades 11a and 11b in the flow rate adjusting members 4A to 4F is set to almost half open, and the user or the administrator opening the air volume adjusting blades 11a and 11b in the flow rate adjusting members 4A to 4F. When the degree is specified, the opening degree is set.

引き続いて、流体送出装置2の電源を入れて作動させ(ステップ302)、その後、各流量調整部材4A〜4Fの流量を測定(検知)し、それら流量調整部材4A〜4Fを流れる流体の流量とそれぞれの目標流量(所定流量値およびその許容範囲)とが比較される(ステップ303)。次いで、1つでも流量調整部材の測定流量値が、目標流量になっていないものが有るか否かが判別(ステップ304)される。各流量調整部材4A〜4Fそれぞれの測定流量値が目標流量になっていれば、目標流量に設定されている(NO)、と判断され、この調整モードは終了する。   Subsequently, the fluid delivery device 2 is turned on and operated (step 302). Thereafter, the flow rate of each of the flow rate adjusting members 4A to 4F is measured (detected), and the flow rate of the fluid flowing through these flow rate adjusting members 4A to 4F Each target flow rate (predetermined flow rate value and its allowable range) is compared (step 303). Next, it is determined whether there is any measured flow rate value of the flow rate adjusting member that does not reach the target flow rate (step 304). If the measured flow rate value of each of the flow rate adjusting members 4A to 4F is the target flow rate, it is determined that the target flow rate is set (NO), and this adjustment mode ends.

1つでも流量調整部材の測定流量値が、目標流量になっていなければ(YES)、すべての流量調整部材4A〜4Fについて流量の再調整が実行される。ところで、ステップ303において各流量調整部材4A〜4Fの測定流量と目標流量とが比較され、測定流量値が目標流量になっていない流量調整部材が1つでも有るか否かがステップ304で判別されるとき、後に行う調整作業では調整しきれない程の著しい差異が生じている流量調整部材が存在することも考えられる。そのような場合には、その流量調整部材を「見直し候補調整部材」として情報処理装置22に入力して記憶する。   If at least one of the measured flow rate values of the flow rate adjusting member does not reach the target flow rate (YES), readjustment of the flow rate is executed for all the flow rate adjusting members 4A to 4F. Incidentally, in step 303, the measured flow rate of each of the flow rate adjusting members 4A to 4F is compared with the target flow rate, and it is determined in step 304 whether or not there is any flow rate adjusting member whose measured flow rate value is not the target flow rate. It is also conceivable that there is a flow rate adjusting member that has a significant difference that cannot be adjusted by the adjustment work performed later. In such a case, the flow rate adjusting member is input and stored in the information processing apparatus 22 as a “review candidate adjusting member”.

ステップ304において測定流量が目標流量になっていない流量調整部材が1つでも有ると判別(YES)されると、すべての流量調整部材4A〜4Fの調整を行うための順番が決定される(ステップ305)。この順番は、通常、上流側(流体送給装置2に近い側)からとするが、ユーザー又は管理者の希望があれば、それに従った順番で行ってもよい。ただし、下流側に位置する流量調整部材の流量を最初に調整すると、その後に上流側の流量調整部材の流量を調整したとき、既に調整した下流側の流量調整部材に狂いが生じることが多いので、調整作業の回数が多くなり好ましくはない。   If it is determined in step 304 that there is at least one flow rate adjusting member whose measured flow rate is not the target flow rate (YES), the order for adjusting all the flow rate adjusting members 4A to 4F is determined (step). 305). This order is usually from the upstream side (side closer to the fluid feeding device 2), but if desired by the user or administrator, the order may be followed. However, if the flow rate of the flow rate adjustment member located on the downstream side is adjusted first, then when the flow rate of the flow rate adjustment member on the upstream side is adjusted thereafter, the flow rate adjustment member on the downstream side that has already been adjusted often becomes distorted. This is not preferable because the number of adjustment operations increases.

その後、決められた順番で全ての流量調整部材4A〜4Fの風量調整羽根11a,11bを図6に示される有効制御範囲内で回転し、それぞれの流量調整部材4A〜4Fの流量をそれぞれの目標流量に調整する(ステップ306)。次いで、全ての流量調整部材4A〜4Fの測定流量が目標流量に達したか否かが判別(ステップ307)され、目標流量に達した(YES)と判別されればこの調整モードは終了する。しかし、流量調整部材4A〜4Fの1つでもその測定流量値が目標流量に達していない場合(NO)には、全ての流量調整部材4A〜4Fについて規定回数だけステップ306を実施したか否かが判別され(ステップ308)、規定回数だけ流量調整が行われていなければ、ステップ304の前に戻って全ての流量調整部材4A〜4Fについて有効制御範囲内で微調整を含む再調整が実施される。   Thereafter, the air volume adjusting blades 11a and 11b of all the flow rate adjusting members 4A to 4F are rotated within the effective control range shown in FIG. 6 in the determined order, and the flow rates of the respective flow rate adjusting members 4A to 4F are set to the respective target values. The flow rate is adjusted (step 306). Next, it is determined whether or not the measured flow rates of all the flow rate adjusting members 4A to 4F have reached the target flow rate (step 307), and if it is determined that the target flow rate has been reached (YES), this adjustment mode ends. However, if the measured flow rate value of one of the flow rate adjusting members 4A to 4F does not reach the target flow rate (NO), whether or not step 306 has been performed a specified number of times for all the flow rate adjusting members 4A to 4F. Is determined (step 308), and if the flow rate adjustment has not been performed a predetermined number of times, the flow returns to the step before step 304, and readjustment including fine adjustment is performed within the effective control range for all the flow rate adjustment members 4A to 4F. The

つまり、全ての流量調整部材4A〜4Fについて定められた順番で流量調整が実施されたとき、例えば最後に実施した流量調整部材の調整で、既に調整した流量調整部材の流量に狂いが生じた場合には、ステップ307でNOの判別結果が出てステップ308に移行する。そこで、全ての流量調整部材4A〜4Fについて規定回数だけ流量調整作業が行われていなければ、再びステップ306の前に戻って最初から調整がやり直され、狂いの生じた流量調整部材について流量が再調整され、また他の流量調整部材についても再調整されることになる。   That is, when the flow rate adjustment is performed in the order determined for all of the flow rate adjustment members 4A to 4F, for example, when the flow rate of the flow rate adjustment member that has already been adjusted is out of order due to the adjustment of the flow rate adjustment member that was last performed. In step 307, a NO determination result is output, and the process proceeds to step 308. Therefore, if the flow rate adjustment work has not been performed the specified number of times for all the flow rate adjustment members 4A to 4F, the flow returns to step 306 and the adjustment is performed again from the beginning. It is adjusted and the other flow rate adjusting members are readjusted.

このようにして、すべての流量調整部材4A〜4Fが、規定回数に亘りそれぞれの目標流量になるまで調整が繰り返される。その間、すべての流量調整部材4A〜4Fの測定流量が目標流量になればその調整モードは終了し、規定回数実施しても測定流量が目標流量にならない流量調整部材があれば、その流量調整部材の流量調整を中止し、その流量調整部材の風量調整羽根11a,11bを全開にするか、或いはユーザー又は管理者が指定する任意の開度に設定(ステップ309)して調整モードを終了する。   In this way, the adjustment is repeated until all the flow rate adjusting members 4A to 4F reach their respective target flow rates for a specified number of times. In the meantime, if the measured flow rate of all the flow rate adjusting members 4A to 4F reaches the target flow rate, the adjustment mode is completed. The flow rate adjustment is stopped, and the air volume adjustment blades 11a and 11b of the flow rate adjustment member are fully opened, or set to an arbitrary opening degree designated by the user or administrator (step 309), and the adjustment mode is terminated.

なお、ステップ303〜304における流量検知、流量比較及び判別で、「見直し候補調整部材」があって、それが情報処理装置22に記憶されている場合には、ステップ309においてその旨がディスプレイなどに表示され、ユーザー又は管理者に対して知らせる。   If there is a “reviewed candidate adjustment member” in the flow rate detection, flow rate comparison, and determination in steps 303 to 304 and is stored in the information processing device 22, that fact is displayed on the display or the like in step 309. Display and inform user or administrator.

以上の説明から明らかなように、図10のフローチャート図に示される調整モードは、要するに、各流量調整部材を1つ1つ正確に目標流量に設定して行くのではなく、ある流量調整部材の流量を目標流量に設定することにより他の流量調整部材の流量に狂いが生じても、決定された調整順に従って全ての流量調整部材4A〜4Fを調整し、次のステップで、目標流量にならない流量調整部材があるかを調べ、あればそれを含めたすべての流量調整部材を再調整する、という方法である。その結果、調整作業が短時間で行え、しかも所定流量に対して前後数パーセントの許容範囲を持たせていることから一層調整時間の短縮化と調整作業労力の軽減化を図ることができる。   As is apparent from the above description, the adjustment mode shown in the flowchart of FIG. 10 is not to set each flow rate adjustment member to the target flow rate one by one. Even if the flow rate of the other flow rate adjustment members becomes distorted by setting the flow rate to the target flow rate, all the flow rate adjustment members 4A to 4F are adjusted according to the determined adjustment order, and the target flow rate is not reached in the next step. This is a method in which it is checked whether there is a flow rate adjusting member, and if there is, the flow rate adjusting members including it are readjusted. As a result, the adjustment work can be performed in a short time, and an allowable range of several percent before and after the predetermined flow rate is provided, so that the adjustment time can be further shortened and the adjustment work labor can be further reduced.

図8,図9のフローチャート図に示す調整モード及び図10のフローチャート図に示す調整モードのいずれの場合でも、該調整モードが終了すると、流量調整装置20は流体搬送設備から撤去される。すなわち、該流量調整装置20を構成する作動装置24および操作力検知装置25がそれぞれの流量調整部材4A〜4Fから取り外され、また流量検知装置23の流量センサー23aが各ダクト内から取り外され、各制御装置27、流量検知装置23、情報処理装置22と共に流体搬送設備の搬送系統1から撤去される。撤去された流量調整装置20は、別な流体搬送設備において施工直後の流量調整に用いられる。   In both cases of the adjustment mode shown in the flowcharts of FIGS. 8 and 9 and the adjustment mode shown in the flowchart of FIG. 10, when the adjustment mode ends, the flow rate adjusting device 20 is removed from the fluid conveyance facility. That is, the operation device 24 and the operating force detection device 25 constituting the flow rate adjustment device 20 are removed from the respective flow rate adjustment members 4A to 4F, and the flow rate sensor 23a of the flow rate detection device 23 is removed from each duct. The control device 27, the flow rate detection device 23, and the information processing device 22 are removed from the transport system 1 of the fluid transport facility. The removed flow rate adjustment device 20 is used for flow rate adjustment immediately after construction in another fluid conveyance facility.

前述した本発明の好適な実施形態では、情報処理装置22と第1〜6流量調整ユニット21の各制御装置27とは有線LANや無線LANなどで電気的に接続することができる。また、各流量調整ユニット21において制御装置27と、操作力検知装置25および流量検知装置23との電気的な接続は有線や無線を用いることができる。   In the above-described preferred embodiment of the present invention, the information processing device 22 and the control devices 27 of the first to sixth flow rate adjustment units 21 can be electrically connected by a wired LAN, a wireless LAN, or the like. Further, in each flow rate adjustment unit 21, electrical connection between the control device 27, the operating force detection device 25 and the flow rate detection device 23 can be wired or wireless.

なお、前述した本発明の実施形態では、説明の便宜上、同一構成の流量調整部材4A〜4Fを用いた例であったが、それぞれの流量調整部材4A〜4Fの構成が同一である必要はまったくない。したがって、第1流量調整部材4Aが3枚の風量調整羽根から構成され、第2流量調整部材4Bが図3に示されるように2枚の風量調整羽根から構成されたものであっても本発明の効果に何ら影響を与えるものではない。   In the above-described embodiment of the present invention, the flow rate adjusting members 4A to 4F having the same configuration are used for convenience of explanation. However, it is absolutely necessary that the configurations of the flow rate adjusting members 4A to 4F are the same. Absent. Therefore, even if the first flow rate adjusting member 4A is composed of three air volume adjusting blades and the second flow rate adjusting member 4B is composed of two air volume adjusting blades as shown in FIG. It has no effect on the effect.
