図２は図１に示すダクト式空気調和システムにおいて吹出口数を変更した例を示す図である。被空調空間１０−１には、ダクト分岐部７−１の端部に３つの吹出口８−１が配置され、被空調空間１０−２には、ダクト分岐部７−２の端部に２つの吹出口８−２が配置され、被空調空間１０−３には、ダクト分岐部７−３の端部に１つの吹出口８−３が配置されている。図２ではダンパ９−１が開状態であり、ダンパ９−２，９−３が閉状態であると仮定する。この場合、室内機２から供給される調和空気は、ダクト分岐部７−１を通流して３つの吹出口８−１から被空調空間１０−１に供給されるが、被空調空間１０−２，１０−３には供給されない。このとき、被空調空間１０−１，１０−２，１０−３に供給される調和空気の度合を表す開口比は、例えば複数の吹出口８−１，８−２，８−３の吹出口数総和と、開状態のダンパ９−１を有するダクト分岐部７−１に設けられた開口吹出口である３つの吹出口８−１の開口吹出口数総和とを用いて求められる。すなわち、図２の例では、吹出口数総和に対する開口吹出口数総和の比率である開口比が５０％となる。また図２の例では、サーミスタ１１で検出される室温が２９℃であり、目標温度が２７℃であり、室内機２が冷房運転中であり、風量段数が５段であると仮定する。以下、図２に示すダクト式空気調和システム１の例を用いて室内機２の制御風量を算出する機能を具体的に説明する。   FIG. 2 is a diagram showing an example in which the number of outlets is changed in the duct type air conditioning system shown in FIG. In the air-conditioned space 10-1, three outlets 8-1 are arranged at the end of the duct branch 7-1, and in the air-conditioned space 10-2, 2 at the end of the duct branch 7-2. One air outlet 8-2 is arranged, and one air outlet 8-3 is arranged at the end of the duct branching portion 7-3 in the air-conditioned space 10-3. In FIG. 2, it is assumed that the damper 9-1 is open and the dampers 9-2 and 9-3 are closed.

At this time, the opening ratio representing the degree of conditioned air supplied to the air-conditioned spaces 10-1, 10-2, 10-3 is, for example, the outlets of the plurality of outlets 8-1, 8-2, 8-3. It is obtained by using the sum of numbers and the sum of the numbers of the opening air outlets of the three air outlets 8-1 which are the opening air outlets provided in the duct branching portion 7-1 having the damper 9-1 in the open state. That is, in the example of FIG. 2, the opening ratio, which is the ratio of the total number of opening outlets to the total number of outlets, is 50%. In the example of FIG. 2, it is assumed that the room temperature detected by the thermistor 11 is 29 ° C., the target temperature is 27 ° C., the indoor unit 2 is in cooling operation, and the number of airflow stages is five. Hereinafter, the function of calculating the control air volume of the indoor unit 2 will be described in detail using the example of the duct type air conditioning system 1 shown in FIG.

Further, the thermistor 11 is not limited to the one built in the controller 6, and may be arranged at any location in the air-conditioned space.

Calculate the sum of the open outlets Opening outlet total sum calculating section 44, opening ratio calculating section 45, temperature difference calculating section 46 for calculating a temperature difference between the target temperature and room temperature based on target temperature information b and room temperature information d, and air volume automatic manual The air volume setting determination unit 42 that determines whether the air volume adjustment is automatically performed or manually performed based on the setting information c, and the air volume stage number, the aperture ratio, the temperature difference, and the control air volume are associated with each other. When it is determined that the control air volume table 47 and the air volume adjustment are automatic, the temperature difference calculated by the temperature difference calculating section 46, the opening ratio calculated by the opening ratio calculating section 45, and the air volume stored in the storage section 41 A control air volume determining unit 48 that compares the number of stages with the control air volume table 47 to determine and output the control air volume 48a.

開口比算出部４５は、吹出口数総和算出部４３で算出された吹出口数総和と開口吹出口数総和算出部４４で算出された開口吹出口数総和とを用いて、被空調空間１０−１，１０−２，１０−３に供給される調和空気の度合い、すなわち吹出口数総和に対する開口吹出口数総和の比率である開口比を算出する。図２の例では開口比が５０％である。   The opening ratio calculating unit 45 uses the total number of outlets calculated by the total number of outlets calculating unit 43 and the total number of outlets calculated by the total number of opening outlets 44 by using the total number of opening outlets 10−. The degree of the conditioned air supplied to 1, 10-2, 10-3, that is, the opening ratio that is the ratio of the total number of opening outlets to the total number of outlets is calculated. In the example of FIG. 2, the aperture ratio is 50%.

温度差算出部４６では、室内機２が冷房運転中であるか暖房運転中であるかを考慮して温度差が算出される。例えば冷房運転中の場合、温度差算出部４６は（１）式で温度差を算出し、暖房運転中の場合、温度差算出部４６は（２）式で温度差を算出する。
（１）温度差＝室温−目標温度
（２）温度差＝目標温度−室温In the temperature difference calculation unit 46, the temperature difference is calculated in consideration of whether the indoor unit 2 is in a cooling operation or a heating operation. For example, when the cooling operation is being performed, the temperature difference calculation unit 46 calculates the temperature difference using Equation (1), and when the heating operation is being performed, the temperature difference calculation unit 46 calculates the temperature difference using Equation (2).
(1) Temperature difference = room temperature-target temperature (2) Temperature difference = target temperature-room temperature

図４は図３に示す制御風量テーブルの例を示す図である。制御風量テーブル４７には、１段から５段までの風量段数と、風量段数の値に対応付けられた１または複数の開口比を表す開口比ステージＲ１１からＲ５５と、温度差の値に対応付けられた複数の温度差ステージＳ１からＳ７と、室内機２の調和空気の排出風量を制御するための複数の制御風量とが対応付けられている。制御風量は、開口比が高いほど風量を強める傾向の制御量、または温度差が大きいほど風量を強める傾向の制御量である。「超強」、「強」、「弱」、「静」、「超静」、および「前回維持」で示されるものが制御風量の度合いを表す。図４では説明を簡単化するために制御風量を文字で表しているが、実際には制御風量に対応した値が設定されているものとする。制御風量テーブル４７の内容は、例えばコントローラ６が設置される環境に合わせて風量の強弱を部分的に変更することができるものとする。   FIG. 4 is a diagram showing an example of the control air volume table shown in FIG. In the control air volume table 47, the air flow stage number from 1 to 5 and the opening ratio stages R11 to R55 representing one or more opening ratios associated with the air flow stage value and the temperature difference value are associated. The plurality of temperature difference stages S <b> 1 to S <b> 7 and the plurality of control airflows for controlling the exhaust airflow of the conditioned air of the indoor unit 2 are associated with each other. The control air volume is a control quantity that tends to increase the air volume as the aperture ratio is high, or a control quantity that tends to increase the air volume as the temperature difference increases. What is indicated by “super strong”, “strong”, “weak”, “static”, “super quiet”, and “previous maintenance” represents the degree of control airflow. In FIG. 4, the control air volume is represented by letters for the sake of simplicity, but it is assumed that a value corresponding to the control air volume is actually set. It is assumed that the contents of the control air volume table 47 can partially change the intensity of the air volume according to the environment in which the controller 6 is installed, for example.

例えば、風量段数情報ｅで得られた風量段数が５段、開口比算出部４５で算出された開口比が４０％以上６０％未満、温度差算出部４６で算出された温度差が６℃以上である場合、制御風量決定部４８では、図中（１）で示す「超強」に対応する制御風量４８ａを決定する。同様にして風量段数が５段、開口比が２０％未満、温度差が１℃未満の場合、制御風量決定部４８では、図中（２）で示す「超静」に対応する制御風量４８ａを決定する。   For example, the airflow stage number obtained from the airflow stage number information e is 5, the opening ratio calculated by the opening ratio calculation unit 45 is 40% or more and less than 60%, and the temperature difference calculated by the temperature difference calculation unit 46 is 6 ° C. or more. If so, the control air volume determining unit 48 determines the control air volume 48a corresponding to “super strong” indicated by (1) in the figure. Similarly, when the number of air flow stages is 5, the opening ratio is less than 20%, and the temperature difference is less than 1 ° C., the control air volume determining unit 48 sets the control air volume 48a corresponding to “super-quiet” shown in FIG. decide.

以下動作を説明する。図５は図１に示す制御装置の動作を示すフローチャートである。制御装置４の風量設定判定部４２において風量調整が自動で行われる設定であると判定された場合（ステップＳ１，Ｙｅｓ）、吹出口数総和算出部４３では吹出口数総和が算出され、開口吹出口数総和算出部４４では開口吹出口数総和が算出され、温度差算出部４６では室内機２が冷房運転中であるか暖房運転中であるかを判断して温度差が算出される（ステップＳ２）。図２の例では吹出口数総和が６であり、開口吹出口数総和が３であり、温度差が２℃である。開口比算出部４５では開口比が算出され（ステップＳ３）、図２の例では開口比が５０％となる。制御風量決定部４８では、制御風量テーブル４７が参照され、制御風量４８ａが決定される（ステップＳ４）。具体的には、風量段数が５段、開口比が５０％、および温度差が２℃であるため、制御風量決定部４８では、制御風量テーブル４７の開口比ステージＲ５３と温度差ステージＳ３とに対応する「弱」の制御風量４８ａが決定される。決定された制御風量４８ａは室内機２へ送信される（ステップＳ５）。   The operation will be described below. FIG. 5 is a flowchart showing the operation of the control device shown in FIG. When it is determined in the air volume setting determination unit 42 of the control device 4 that the air volume adjustment is automatically performed (step S1, Yes), the air outlet number total calculation unit 43 calculates the air outlet number total, The total outlet number calculating unit 44 calculates the total number of open outlets, and the temperature difference calculating unit 46 determines whether the indoor unit 2 is in cooling operation or heating operation, and calculates the temperature difference (step) S2). In the example of FIG. 2, the total number of outlets is 6, the total number of open outlets is 3, and the temperature difference is 2 ° C. The aperture ratio calculation unit 45 calculates the aperture ratio (step S3), and the aperture ratio is 50% in the example of FIG. The control air volume determination unit 48 refers to the control air volume table 47 and determines the control air volume 48a (step S4). Specifically, since the number of airflow stages is 5, the opening ratio is 50%, and the temperature difference is 2 ° C., the control airflow determination unit 48 sets the opening ratio stage R53 of the control airflow table 47 and the temperature difference stage S3. The corresponding “weak” control air volume 48a is determined. The determined control air volume 48a is transmitted to the indoor unit 2 (step S5).

風量調整が自動で行われる設定ではないと判定された場合（ステップＳ１，Ｎｏ）、コントローラ６においてユーザが設定した風量を室内機２に送信する（ステップＳ６）。   When it is determined that the air volume adjustment is not automatically performed (step S1, No), the air volume set by the user in the controller 6 is transmitted to the indoor unit 2 (step S6).

実施の形態１のダクト式空気調和システム１では、ダンパの開閉状態および吹出口の数に着目することで、開状態または閉状態に制御されるダンパを使用しながらも、吹出口の開口数が多いときまたは温度差が大きい場合、風量を強め、吹出口の開口数が少なくまたは温度差が小さい場合、風量を弱めるという制御を実現することができる。従って、開度を細かく制御可能なダンパと静圧過不足情報およびダンパ開度を取得するためのＶＡＶコンロールユニットとを用いる必要がなく、ユーザはダクト式空気調和システムを低コストで構築することが可能となる。   In the duct type air conditioning system 1 of the first embodiment, by focusing on the damper open / closed state and the number of outlets, the numerical aperture of the outlet is reduced while using the damper controlled to be in the open state or the closed state. When it is large or when the temperature difference is large, it is possible to realize a control in which the air volume is increased, and when the numerical aperture of the air outlet is small or the temperature difference is small, the air volume is decreased. Therefore, it is not necessary to use a damper capable of finely controlling the opening degree and a VAV control unit for acquiring the static pressure excess / deficiency information and the damper opening degree, and the user can construct a duct type air conditioning system at a low cost. It becomes possible.

実施の形態２．
図６は本発明の実施の形態２に係るダクト式空気調和システムの構成図である。実施の形態１のダクト式空気調和システム１との違いは以下の通りである。ダクト式空気調和システム１Ａでは、コントローラ６にサーミスタ１１−１が設けられ、被空調空間１０−１以外の複数の被空調空間１０−２・・・１０−ｎの内、被空調空間１０−２にはサーミスタ１１−２が設けられ、被空調空間１０−ｎにはサーミスタ１１−ｎが設けられている。ｎは１以上の整数である。サーミスタ１１−２・・・１１−ｎで各々検出された室温情報１１ａは、制御線１２で制御装置４へ送信される。以下、実施の形態１と同一部分には同一符号を付してその説明を省略し、ここでは異なる部分についてのみ述べる。Embodiment 2. FIG.
FIG. 6 is a configuration diagram of a duct-type air conditioning system according to Embodiment 2 of the present invention. The difference from the duct type air conditioning system 1 of Embodiment 1 is as follows. In the duct type air conditioning system 1A, the thermistor 11-1 is provided in the controller 6, and the air-conditioned space 10-2 among the plural air-conditioned spaces 10-2 to 10-n other than the air-conditioned space 10-1. Is provided with a thermistor 11-2, and the to-be-conditioned space 10-n is provided with a thermistor 11-n. n is an integer of 1 or more. The room temperature information 11a detected by the thermistors 11-2... 11-n is transmitted to the control device 4 through the control line 12. Hereinafter, the same reference numerals are given to the same parts as those in the first embodiment, and the description thereof is omitted, and only different parts will be described here.

図７は図６に示す制御装置内の制御風量算出部の第１の構成例を表す図である。制御風量算出部４１０は、コントローラ出力情報６ａと室内機出力情報２ａとサーミスタ１１−１，１１−２・・・１１−ｎで各々検出された室温情報１１ａとを受信する情報受信部４０Ａと、吹出口数情報ａ、目標温度情報ｂ、風量自動手動設定情報ｃ、室温情報ｄ、風量段数情報ｅ、ダンパ開閉状態情報ｆ、および室温情報１１ａを記憶する記憶部４１Ａと、風量設定判定部４２と、吹出口数総和算出部４３と、開口吹出口数総和算出部４４と、開口比算出部４５と、室温情報ｄ、ダンパ開閉状態情報ｆ、および室温情報１１ａに基づいてダンパが開口状態の吹出口が配置された複数の被空調空間の温度を平均化した温度を算出する平均温度算出部４９と、平均温度算出部４９で算出された平均温度と目標温度との温度差を算出する温度差算出部４６Ａと、開口比算出部４５と、制御風量テーブル４７と、制御風量決定部４８とを有する。   FIG. 7 is a diagram illustrating a first configuration example of the control air volume calculation unit in the control device illustrated in FIG. 6. The control air volume calculation unit 410 receives the controller output information 6a, the indoor unit output information 2a, and the room temperature information 11a detected by the thermistors 11-1, 11-2,. A storage unit 41A for storing outlet number information a, target temperature information b, air volume automatic manual setting information c, room temperature information d, air volume stage number information e, damper open / close state information f, and room temperature information 11a, and air volume setting determination unit 42 The opening number sum calculating unit 43, the opening number calculating unit 44, the opening ratio calculating unit 45, the room temperature information d, the damper opening / closing state information f, and the room temperature information 11a. An average temperature calculation unit 49 that calculates a temperature obtained by averaging the temperatures of a plurality of air-conditioned spaces in which the air outlets are arranged, and a temperature that calculates a temperature difference between the average temperature calculated by the average temperature calculation unit 49 and the target temperature It has a calculating unit 46A, and the opening ratio calculation unit 45, a control air volume table 47, and a control air amount determining unit 48.

実施の形態１のダクト式空気調和システム１では、サーミスタ１１からの室温情報ｄを用いて制御風量４８ａが決定されたが、ダクト式空気調和システム１Ａでは、ダンパの状態が開になっている複数の被空調空間で検出された複数の温度を用いて制御風量４８ａが決定される。例えば図６に示す被空調空間１０−１，１０−２のダンパ９−１，９−２のみが開状態である場合、平均温度算出部４９は、ダンパ開閉状態情報ｆによりダンパが開口状態の吹出口が配置された被空調空間１０−１，１０−２を特定し、被空調空間１０−１に配置されたサーミスタ１１−１で検出された室温と被空調空間１０−２のサーミスタ１１−２で検出された室温との平均値を算出する。温度差算出部４６Ａは、平均温度算出部４９で算出された平均値を、温度差を算出するための室温として使用する。これにより被空調空間１０−１と被空調空間１０−２の温度むらを軽減することができる。   In the duct type air conditioning system 1 of the first embodiment, the control air volume 48a is determined using the room temperature information d from the thermistor 11, but in the duct type air conditioning system 1A, a plurality of dampers are open. The control air volume 48a is determined using a plurality of temperatures detected in the air-conditioned space. For example, when only the dampers 9-1 and 9-2 of the air-conditioned spaces 10-1 and 10-2 shown in FIG. 6 are in the open state, the average temperature calculation unit 49 indicates that the damper is in the open state based on the damper open / close state information f. The air-conditioned spaces 10-1 and 10-2 in which the air outlets are arranged are specified, the room temperature detected by the thermistor 11-1 arranged in the air-conditioned space 10-1 and the thermistor 11- in the air-conditioned space 10-2. The average value with the room temperature detected by 2 is calculated. The temperature difference calculation unit 46A uses the average value calculated by the average temperature calculation unit 49 as the room temperature for calculating the temperature difference. Thereby, the temperature nonuniformity of the air-conditioned space 10-1 and the air-conditioned space 10-2 can be reduced.

図８は図６に示す制御装置内の制御風量算出部の第２の構成例を表す図である。制御風量算出部４２０は、情報受信部４０Ａと、記憶部４１Ａと、風量設定判定部４２と、吹出口数総和算出部４３と、開口吹出口数総和算出部４４と、開口比算出部４５と、吹出口数情報ａ、室温情報ｄ、ダンパ開閉状態情報ｆ、および室温情報１１ａに基づいてダンパが開口状態の吹出口が配置された複数の被空調空間の温度を加重平均化した温度を算出する加重平均温度算出部５０と、加重平均温度算出部５０で算出された加重平均温度と目標温度との温度差を算出する温度差算出部４６Ｂと、開口比算出部４５と、制御風量テーブル４７と、制御風量決定部４８とを有する。   FIG. 8 is a diagram illustrating a second configuration example of the control air volume calculation unit in the control device illustrated in FIG. 6. The control air volume calculation unit 420 includes an information reception unit 40A, a storage unit 41A, an air volume setting determination unit 42, an outlet number total calculation unit 43, an opening outlet number total calculation unit 44, and an opening ratio calculation unit 45. Based on the air outlet number information a, the room temperature information d, the damper open / close state information f, and the room temperature information 11a, a temperature obtained by weighted averaging the temperatures of the plurality of air-conditioned spaces in which the air outlets with the dampers opened is calculated. A weighted average temperature calculating unit 50, a temperature difference calculating unit 46B for calculating a temperature difference between the weighted average temperature calculated by the weighted average temperature calculating unit 50 and the target temperature, an opening ratio calculating unit 45, and a control air volume table 47. And a control air volume determination unit 48.

吹出口数が多い被空調空間は面積が広く、空調され難いことが想定される。ダクト式空気調和システム１Ｂでは、ダンパの状態が開になっている複数の被空調空間で検出された複数の温度を用いて、複数の被空調空間の吹出口数に基づく温度の重みづけを行う。重みづけの方法としては吹出口数と室温の加重平均を用いる。例えば図６のダクト式空気調和システム１Ａにおいて、被空調空間１０−１，１０−２のダンパ９−１，９−２が開状態であり、被空調空間１０−１の室温が３０℃で吹出口が５つであり、被空調空間１０−２の室温が２５℃で吹出口が１つである場合、加重平均温度算出部５０は、吹出口数情報ａとダンパ開閉状態情報ｆにより、ダンパが開口状態の吹出口が配置された被空調空間１０−１，１０−２の開口吹出口の数を求め、（３）式で加重平均温度を求める。
（３）加重平均温度＝（３０×５＋２５×１）／６＝２９．２℃It is assumed that the air-conditioned space with a large number of outlets has a large area and is difficult to be air-conditioned. In the duct type air conditioning system 1B, the temperature is weighted based on the number of outlets of the plurality of air-conditioned spaces using the plurality of temperatures detected in the plurality of air-conditioned spaces whose dampers are open. . As a weighting method, a weighted average of the number of outlets and room temperature is used. For example, in the duct type air conditioning system 1A of FIG. 6, the dampers 9-1 and 9-2 of the air-conditioned spaces 10-1 and 10-2 are in the open state, and the room temperature of the air-conditioned space 10-1 is blown at 30 ° C. When the number of outlets is five, the room temperature of the air-conditioned space 10-2 is 25 ° C., and there is one outlet, the weighted average temperature calculation unit 50 calculates the damper based on the outlet number information a and the damper open / close state information f. The number of opening air outlets of the air-conditioned spaces 10-1 and 10-2 in which the air outlets in the open state are arranged is obtained, and the weighted average temperature is obtained by equation (3).
(3) Weighted average temperature = (30 × 5 + 25 × 1) /6=29.2° C.

例えば風量段数が５段、開口比が５０％、目標温度が２５℃、また室内機２が冷房運転中であると仮定した場合、図７に示す制御風量算出部４１０の平均温度算出部４９で算出される温度は２７．５であり、温度差算出部４６Ａで算出される温度差は２．５℃となる。これに対して図８に示す制御風量算出部４２０の加重平均温度算出部５０で算出される温度は２９．２℃であるため、温度差算出部４６Ｂで算出される温度差は４．２℃になる。温度差が２．５℃である場合、制御風量決定部４８では図４に示す「弱」の制御風量４８ａが決定されるが、温度差が４．２℃である場合、制御風量決定部４８では図４に示す「強」の制御風量４８ａが決定される。このように空調され難い被空調空間１０−１を考慮した風量の決定を行うことができ、被空調空間１０−１の室温を目標温度へより早く近づけることができる。   For example, when it is assumed that the number of airflow stages is 5, the opening ratio is 50%, the target temperature is 25 ° C., and the indoor unit 2 is in the cooling operation, the average temperature calculation unit 49 of the control airflow calculation unit 410 shown in FIG. The calculated temperature is 27.5, and the temperature difference calculated by the temperature difference calculation unit 46A is 2.5 ° C. On the other hand, since the temperature calculated by the weighted average temperature calculation unit 50 of the control air volume calculation unit 420 shown in FIG. 8 is 29.2 ° C., the temperature difference calculated by the temperature difference calculation unit 46B is 4.2 ° C. become. When the temperature difference is 2.5 ° C., the control air volume determining unit 48 determines the “weak” control air volume 48a shown in FIG. 4, but when the temperature difference is 4.2 ° C., the control air volume determining unit 48 is. Then, the “strong” control air volume 48a shown in FIG. 4 is determined. Thus, the air volume can be determined in consideration of the air-conditioned space 10-1 that is difficult to be air-conditioned, and the room temperature of the air-conditioned space 10-1 can be brought closer to the target temperature sooner.

なお実施の形態１，２では、吹出口数総和と開口吹出口数総和とを用いて開口比を算出する例を説明したが、複数の吹出口の各々の断面積が異なる場合を考慮して開口比は吹出口面積総和と開口吹出口面積総和とを用いて求めてもよい。   In the first and second embodiments, the example in which the opening ratio is calculated using the total number of outlets and the total number of opening outlets has been described. However, in consideration of the case where the cross-sectional areas of the plurality of outlets are different. The opening ratio may be obtained using the total outlet area and the total opening area.

以上に説明したように実施の形態１，２のダクト式空気調和システム１，１Ａは、空気調和機と、前記空気調和機の調和空気が供給される複数の被空調空間に対応して配置された複数のダクト内に各々設けられ、個々のダクト内の風路を開または閉の状態にする複数のダンパと、前記複数のダクトの端部に各々配置される複数の吹出口と、前記空気調和機および前記複数のダンパを制御する制御装置と、を備え、前記制御装置は、前記空気調和機が自動で風量調整を行うとき、前記複数の被空調空間に各々設けられた前記複数の吹出口の数または面積の総和に対する開状態のダンパを有するダクトに設けられた開口吹出口の数または面積の総和の比率である開口比と、前記開口吹出口が存在する被空調空間で測定された温度と前記被空調空間の目標温度との温度差と、に基づいて、前記空気調和機を構成する室内機の風量を制御する制御風量を決定する制御風量算出部４００を有する。この構成により、開度を細かく制御可能なダンパと、静圧過不足情報およびダンパ開度を取得するためのＶＡＶコンロールユニットとを用いることなく風量制御を行うことができ、ユーザはダクト式空気調和システムを低コストで構築することができる。またダクト式空気調和システム１，１ＡによればＶＡＶコンロールユニットを用いる必要がないため構成部品の減容化を図ることができる。またダンパは開または閉の動作のみ行うものでよく装置構成が簡素化されることから長寿命化を図ることができる。   As described above, the duct-type air conditioning systems 1 and 1A according to the first and second embodiments are arranged corresponding to the air conditioner and a plurality of air-conditioned spaces to which the conditioned air of the air conditioner is supplied. A plurality of dampers provided in each of the plurality of ducts to open or close the air passages in the individual ducts, a plurality of air outlets respectively disposed at ends of the plurality of ducts, and the air A control device that controls the conditioner and the plurality of dampers, and the control device, when the air conditioner automatically adjusts the air flow, the plurality of blowers respectively provided in the plurality of air-conditioned spaces. Measured in the air-conditioned space in which the opening ratio, which is the ratio of the number or area of the total number of opening outlets provided in the duct having the damper in the open state to the total number or area of outlets, and the opening outlet Temperature and the air-conditioned space It has a temperature difference between the target temperature, based on the control air quantity calculation section 400 which determines the control air volume for controlling the air volume of the indoor units constituting the air conditioner. With this configuration, it is possible to perform air volume control without using a damper capable of finely controlling the opening degree and a VAV control unit for acquiring static pressure excess / deficiency information and damper opening degree. A system can be constructed at low cost. Moreover, according to the duct type air conditioning systems 1 and 1A, it is not necessary to use a VAV control unit, so that the volume of components can be reduced. Further, the damper may only perform an opening or closing operation, and the apparatus configuration is simplified, so that the life can be extended.

また実施の形態２の制御風量算出部４１０は、前記開口吹出口が存在する複数の被空調空間で測定された複数の温度の平均値と前記目標温度との温度差を用いる。この構成により、複数の被空調空間の温度むらを軽減することができる。   Moreover, the control air volume calculation part 410 of Embodiment 2 uses the temperature difference of the average value of several temperature measured in several air-conditioned space where the said opening blower outlet exists, and the said target temperature. With this configuration, temperature unevenness in a plurality of air-conditioned spaces can be reduced.

また実施の形態２の制御風量算出部４２０は、前記開口吹出口が存在する複数の被空調空間で測定された複数の温度を前記開口吹出口の数で加重平均した加重平均温度と前記目標温度との温度差を用いる。この構成により、空調され難い被空調空間の室温を目標温度へより早く近づけることができる。   In addition, the control air volume calculation unit 420 according to the second embodiment includes a weighted average temperature obtained by weighted averaging a plurality of temperatures measured in a plurality of air-conditioned spaces in which the opening air outlets exist, and the target temperature. The difference in temperature is used. With this configuration, the room temperature of the air-conditioned space that is difficult to be air-conditioned can be brought closer to the target temperature sooner.
