The air conditioning system 1 is a system that performs air conditioning of a room (hereinafter, referred to as an air conditioning target area) in a building (here, in a residence in a general household).
　空調システム１は、空調機２（室内機２ａ、室外機２ｂ）と、リモコン３と、ベースダクト４と、第１吹出ダクト５と、第２吹出ダクト６と、第１吸込ダクト７と、第２吸込ダクト８と、ダンパ９と、を含んで構成される。 The air conditioning system 1 includes an air conditioner 2 (indoor unit 2a, outdoor unit 2b), a remote controller 3, a base duct 4, a first blowing duct 5, a second blowing duct 6, a first suction duct 7, A two-suction duct 8 and a damper 9 are included.
　リモコン３は、ユーザからの入力操作を受け付け、受け付けた入力操作に応じた制御信号を通信線１０を介して室内機２ａに送信する。なお、リモコン３は、無線通信により制御信号を室内機２ａに送信してもよい。リモコン３がユーザから受け付ける入力操作には、例えば、運転の開始／停止の切り替え、冷房，暖房，除湿，送風等の運転モードの切り替え、目標温度、風量等の変更等が含まれる。 The remote controller 3 receives an input operation from the user and transmits a control signal corresponding to the received input operation to the indoor unit 2a via the communication line 10.

Specifically, the temperature of the air in the air-conditioning target area sucked through at least one of the first suction duct 7 and the second suction duct 8 is adjusted. Then, the indoor unit 2a sends the adjusted air to the base duct 4. The air sent out to the base duct 4 is sent out to the air-conditioning target area through at least one of the first blowing duct 5 and the second blowing duct 6.

　データ記憶部２２は、例えば、フラッシュメモリ等の読み書き可能な不揮発性の半導体メモリ等で構成され、室内機２ａを制御するためのプログラム（空調制御プログラム）を含む各種のプログラムやこれらのプログラムの実行時に使用されるデータ等を記憶する。データ記憶部２２は、空調制御プログラムの実行時に使用される、本発明特有のデータの１つとして、目標配分テーブル２２０を記憶する。 The data storage unit 22 is composed of, for example, a readable / writable nonvolatile semiconductor memory such as a flash memory, and various programs including a program (air conditioning control program) for controlling the indoor unit 2a and the execution of these programs. Stores data used at times. The data storage unit 22 stores a target distribution table 220 as one of the data unique to the present invention that is used when the air conditioning control program is executed.
　目標配分テーブル２２０は、図３に示すように、運転モードの種別と、第１吹出ダクト５及び第２吹出ダクト６への空気流量の目標配分比（％）とが対応付けられて設定されたデータテーブルである。本実施形態では、運転モードが冷房モードに設定されている場合、第１吹出ダクト５への空気流量の目標配分比は９０％であり、第２吹出ダクト６への空気流量の目標配分比は１０％である。つまり、冷房時では、室内機２ａにより調整された空気の大半を、天井吹出口、即ち、空気対象エリアの上方から吹き出させることが求められている。 As shown in FIG. 3, the target distribution table 220 is set in association with the type of operation mode and the target distribution ratio (%) of the air flow rate to the first blowing duct 5 and the second blowing duct 6. It is a data table. In this embodiment, when the operation mode is set to the cooling mode, the target distribution ratio of the air flow rate to the first blowing duct 5 is 90%, and the target distribution ratio of the air flow rate to the second blowing duct 6 is 10%. That is, at the time of cooling, it is required to blow out most of the air adjusted by the indoor unit 2a from the ceiling outlet, that is, from above the air target area.
　一方、運転モードが暖房モードに設定されている場合、図３では、第１吹出ダクト５への空気流量の目標配分比は１０％であり、第２吹出ダクト６への空気流量の目標配分比は９０％であることが示されている。つまり、暖房時では、室内機２ａにより調整された空気の大半を、床吹出口、即ち、空気対象エリアの下方から吹き出させることが求められている。 On the other hand, when the operation mode is set to the heating mode, in FIG. 3, the target distribution ratio of the air flow rate to the first blowing duct 5 is 10%, and the target distribution ratio of the air flow rate to the second blowing duct 6 is set. Is shown to be 90%. That is, at the time of heating, it is required to blow out most of the air adjusted by the indoor unit 2a from the floor outlet, that is, from below the air target area.
　また、運転モードが送風モードに設定されている場合、図３では、第１吹出ダクト５への空気流量の目標配分比は５０％であり、第２吹出ダクト６への空気流量の目標配分比は５０％であることが示されている。つまり、送風時では、天井吹出口及び床吹出口、即ち、空気対象エリアの上方及び下方から吹き出させる空気の流量は同一になることが求められている。 When the operation mode is set to the air blowing mode, in FIG. 3, the target distribution ratio of the air flow rate to the first blowing duct 5 is 50%, and the target distribution ratio of the air flow rate to the second blowing duct 6 is set. Is shown to be 50%. That is, at the time of ventilation, the flow rate of air blown from the ceiling outlet and the floor outlet, that is, from above and below the air target area, is required to be the same.
　図２に戻り、制御部２３は、ＣＰＵ（Central Processing Unit）、ＲＯＭ（Read Only Memory）、ＲＡＭ（Random Access Memory）等（何れも図示せず）を含んで構成され、室内機２ａを統括制御する。制御部２３は、本発明特有の機能として、配分制御部２３０を備える。 Returning to FIG. 2, the control unit 23 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like (none of which are shown), and controls the indoor unit 2a. To do. The control unit 23 includes a distribution control unit 230 as a function unique to the present invention.
　配分制御部２３０は、現在設定されている運転モードに応じて、第１吹出ダクト５及び第２吹出ダクト６への空気流量の配分比を制御する。図４は、配分制御部２３０により実行される配分制御処理の手順を示すフローチャートである。配分制御部２３０は、室内機２ａの運転が開始されると、配分制御処理の実行を開始し、室内機２ａの運転が停止されると、配分制御処理の実行を停止する。 The distribution control unit 230 controls the distribution ratio of the air flow rate to the first blowing duct 5 and the second blowing duct 6 according to the currently set operation mode. FIG. 4 is a flowchart showing a procedure of distribution control processing executed by the distribution control unit 230. The distribution control unit 230 starts executing the distribution control process when the operation of the indoor unit 2a is started, and stops the execution of the distribution control process when the operation of the indoor unit 2a is stopped.
　配分制御部２３０は、運転モードの設定が変更されたか否かを判別する（ステップＳ１０１）。運転モードの設定が変更された場合（ステップＳ１０１；ＹＥＳ）、配分制御部２３０は、データ記憶部２２に記憶されている目標配分テーブル２２０を参照して、変更された運転モードの種別に対応する目標配分比を取得する（ステップＳ１０２）。 The distribution control unit 230 determines whether or not the operation mode setting has been changed (step S101). When the setting of the operation mode is changed (step S101; YES), the distribution control unit 230 refers to the target distribution table 220 stored in the data storage unit 22 and corresponds to the changed type of operation mode. A target distribution ratio is acquired (step S102).
　配分制御部２３０は、取得した目標配分比に基づいて、ダンパ９の開度を決定する（ステップＳ１０３）。目標配分比とダンパ９の開度との対応関係を示すテーブル（配分比－開度対応テーブル）は、予めデータ記憶部２２に記憶されているものとする。 The distribution control unit 230 determines the opening degree of the damper 9 based on the acquired target distribution ratio (step S103). It is assumed that a table (distribution ratio-opening correspondence table) indicating the correspondence between the target distribution ratio and the opening degree of the damper 9 is stored in the data storage unit 22 in advance.
　なお、当該室内機２ａの出荷段階では、この配分比－開度対応テーブルには、予め想定した設置モデルケースに基づいて決められたデフォルトデータが設定されている。設置業者等の作業者は、当該室内機２ａを購入者宅等に設置する際、実際の設置状況を示す調整パラメータ（例えば、室内機２ａの設置位置と天井面及び床面それぞれとの間の距離や、第１吹出ダクト５及び第２吹出ダクト６それぞれの長さ等）を用いて、配分比－開度対応テーブルの設定内容をカスタマイズするものとする。 Note that at the shipment stage of the indoor unit 2a, default data determined based on an assumed installation model case is set in the distribution ratio-opening correspondence table. When an operator such as an installer installs the indoor unit 2a in a purchaser's house or the like, an adjustment parameter indicating an actual installation state (for example, between the installation position of the indoor unit 2a and the ceiling surface and the floor surface) The setting contents of the distribution ratio-opening correspondence table are customized using the distance, the length of each of the first blowout duct 5 and the second blowout duct 6, and the like.
　配分制御部２３０は、決定したダンパ９の開度を示す制御信号を生成し、生成した制御信号を無線通信によりダンパ９に送信する（ステップＳ１０４）。その後、配分制御部２３０は、再度、ステップＳ１０１の処理を行う。 The distribution control unit 230 generates a control signal indicating the determined opening degree of the damper 9, and transmits the generated control signal to the damper 9 by wireless communication (step S104). Thereafter, the distribution control unit 230 performs the process of step S101 again.
　以上のように、本発明の実施形態に係る空調システム１では、室内機２ａから供給された調整空気を空調対象エリアの上方及び下方の何れからも吹き出せるように構成され、さらに、運転モードに応じて、空調対象エリアの上方から吹き出させる空気の流量と下方から吹き出させる空気の流量の配分比を変更することができる。 As described above, the air conditioning system 1 according to the embodiment of the present invention is configured so that the regulated air supplied from the indoor unit 2a can be blown out from above and below the air conditioning target area, and further, in the operation mode. Accordingly, the distribution ratio between the flow rate of air blown from above the air-conditioning target area and the flow rate of air blown from below can be changed.
　このため、冷たい空気が下降し、暖かい空気が上昇するという気流の特性を利用して、例えば、冷房時ならば、室内機２ａにより調整された空気の大半を、空気対象エリアの上方から吹き出させることができ、暖房時ならば、室内機２ａにより調整された空気の大半を、空気対象エリアの下方から吹き出させることができる。このようにすることで、ユーザの快適性を向上させることが可能となり、結果として省エネルギー性の向上も図れ、ランニングコストを抑えることができる。さらに、上記の空調を１台の空調機２（室内機２ａ，室外機２ｂ）で実現するめ、イニシャルコストも抑えることがきる。 For this reason, utilizing the characteristic of the air flow that cool air descends and warm air rises, for example, during cooling, most of the air adjusted by the indoor unit 2a is blown out from above the air target area. In the case of heating, most of the air adjusted by the indoor unit 2a can be blown out from below the air target area. By doing in this way, it becomes possible to improve a user's comfort, and as a result, an energy-saving property can also be improved and a running cost can be suppressed. Furthermore, since the above air conditioning is realized by one air conditioner 2 (indoor unit 2a, outdoor unit 2b), the initial cost can be suppressed.
　なお、本発明は、上記実施形態に限定されず、本発明の要旨を逸脱しない範囲での種々の変更は勿論可能である。 In addition, this invention is not limited to the said embodiment, Of course, the various change in the range which does not deviate from the summary of this invention is possible.
　例えば、目標配分テーブル２２０の設定内容は任意の設計事項であり、運転モードの種別に応じて、任意の目標配分比を設定してもよいことは勿論である。例えば、何れか一方の目標配分比を１００％に、他方の目標配分比を０％に設定してもよく、その場合、目標配分比が０％に設定された吹出ダクトを介して空調対象エリアに空気が吹き出されることはなく、室内機２ａから供給された空気は、全て他方の吹出ダクトを介して空調対象エリアに送り出されることになる。 For example, the setting contents of the target distribution table 220 are arbitrary design matters, and it is needless to say that an arbitrary target distribution ratio may be set according to the type of operation mode. For example, one of the target distribution ratios may be set to 100%, and the other target distribution ratio may be set to 0%. In this case, the air-conditioning target area is set via the blowout duct having the target distribution ratio set to 0%. No air is blown out, and all the air supplied from the indoor unit 2a is sent to the air-conditioning target area through the other blowing duct.
　また、室内機２ａは、第１吸込温度センサにより計測された温度と第２吸込温度センサにより計測された温度とを現在の目標配分比に基づいて加重平均することで空調対象エリアの代表空気温度を導出してもよい。 Further, the indoor unit 2a performs a weighted average of the temperature measured by the first suction temperature sensor and the temperature measured by the second suction temperature sensor based on the current target distribution ratio, thereby representing the representative air temperature in the air-conditioning target area. May be derived.
　あるいは、室内機２ａは、第１吸込温度センサにより計測された温度と第２吸込温度センサにより計測された温度との何れか一方を予め定めた条件により選択し、選択した温度を空調対象エリアの代表空気温度として空調動作を行ってもよい。この場合、冷房時ならば、第１吸込温度センサにより計測された温度を代表空気温度とし、暖房時ならば、第２吸込温度センサにより計測された温度を代表空気温度としてもよい。 Alternatively, the indoor unit 2a selects either the temperature measured by the first suction temperature sensor or the temperature measured by the second suction temperature sensor according to a predetermined condition, and selects the selected temperature in the air conditioning target area. An air conditioning operation may be performed as the representative air temperature. In this case, the temperature measured by the first suction temperature sensor may be used as the representative air temperature during cooling, and the temperature measured by the second suction temperature sensor may be used as the representative air temperature during heating.
　また、室内機２ａに、吹出ダクトと連結可能な２つの空気吹出口（第１空気吹出口、第２空気吹出口）を設け、図５に示すように、室内機２ａと第１吹出ダクト５及び第２吹出ダクト６のそれぞれとをベースダクト４を介さずに直接に連結する構成にしてもよい。この場合、図１のダンパ９に相当するダンパを室内機２ａの内部に設け、配分制御部２３０は、運転モードに応じて、かかるダンパを制御することで、第１空気吹出口（即ち、第１吹出ダクト５）及び第２空気吹出口（即ち、第２吹出ダクト６）への空気流量の配分比を調整すればよい。 Further, the indoor unit 2a is provided with two air outlets (first air outlet and second air outlet) that can be connected to the outlet duct, and as shown in FIG. 5, the indoor unit 2a and the first outlet duct 5 are provided. In addition, each of the second outlet ducts 6 may be directly connected without the base duct 4 interposed therebetween. In this case, a damper corresponding to the damper 9 in FIG. 1 is provided inside the indoor unit 2a, and the distribution control unit 230 controls the damper according to the operation mode, thereby enabling the first air outlet (that is, the first air outlet). The distribution ratio of the air flow rate to the first outlet duct 5) and the second air outlet (that is, the second outlet duct 6) may be adjusted.
　また、図６に示すように、室内機２ａを天井裏に設置してもよい。図６の例では、室内機２ａには、図５に示す室内機２ａと同様、２つの空気吹出口（第１空気吹出口、第２空気吹出口）が設けられているものの、第１空気吹出口には、第１吹出ダクト５が連結されておらず、また、第１空気吸込口にも第１吸込ダクト７が連結されていない。つまり、図６に示す室内機２ａは、第１空気吸込口から直接に空調対象エリアの空気を吸い込み、第１空気吹出口から直接に空調対象エリアへ空気を送り出す。このような場合においても、上述したように、図１のダンパ９に相当するダンパを室内機２ａの内部に設け、配分制御部２３０は、運転モードに応じて、かかるダンパを制御することで、第１空気吹出口及び第２空気吹出口への空気流量の配分比を調整すればよい。 Further, as shown in FIG. 6, the indoor unit 2a may be installed behind the ceiling. In the example of FIG. 6, the indoor unit 2a is provided with two air outlets (a first air outlet and a second air outlet) as in the indoor unit 2a shown in FIG. The first outlet duct 5 is not connected to the outlet, and the first inlet duct 7 is not connected to the first air inlet. That is, the indoor unit 2a shown in FIG. 6 sucks air in the air-conditioning target area directly from the first air suction port, and sends out air directly from the first air outlet to the air-conditioning target area. Even in such a case, as described above, a damper corresponding to the damper 9 of FIG. 1 is provided inside the indoor unit 2a, and the distribution control unit 230 controls the damper according to the operation mode, The distribution ratio of the air flow rate to the first air outlet and the second air outlet may be adjusted.
　上記と同様に、図７に示すように、室内機２ａを床下に設置してもよい。なお、図５に示す構成の室内機２ａを天井裏や床下に設置することも勿論可能である。 As described above, the indoor unit 2a may be installed under the floor as shown in FIG. Of course, the indoor unit 2a having the configuration shown in FIG. 5 can be installed behind the ceiling or under the floor.
　また、上述した配分制御部２３０によって実行される配分制御処理をリモコン３によって実行されるようにしてもよい。この場合、リモコン３は、室内機２ａを介してダンパ９の開度を調整してもよいし、あるいは、リモコン３とダンパ９とを有線又は無線にて通信可能な構成にして、リモコン３からの制御信号が直接にダンパ９へ送信されるようにしてもよい。 Further, the distribution control process executed by the above-described distribution control unit 230 may be executed by the remote controller 3. In this case, the remote controller 3 may adjust the opening degree of the damper 9 via the indoor unit 2a, or the remote controller 3 and the damper 9 may be configured to communicate with each other by wire or wirelessly. The control signal may be transmitted directly to the damper 9.
　また、上記実施形態では、ダンパ９によって室内機２ａから供給された空気を第１吹出ダクト５と第２吹出ダクト６とに分配していたが、これに換えて、第１吹出ダクト５と第２吹出ダクト６とにそれぞれ別個のダンパ（第１ダンパ、第２ダンパ）を設けるようにしてもよい。この場合においても、第１ダンパ及び第２ダンパは、室内機２ａからの制御信号に従って調整される。また、目標配分比と第１ダンパ及び第２ダンパそれぞれの開度との対応関係を示すテーブルが、予め室内機２ａのデータ記憶部２２に記憶されているものとする。室内機２ａの配分制御部２３０は、かかるテーブルを参照して、現在の目標配分比に対応する第１ダンパ及び第２ダンパそれぞれの開度を決定し、決定した各開度を示す制御信号を第１ダンパ及び第２ダンパそれぞれに送信する。 Moreover, in the said embodiment, although the air supplied from the indoor unit 2a by the damper 9 was distributed to the 1st blowing duct 5 and the 2nd blowing duct 6, it replaces with this and the 1st blowing duct 5 and the 1st blowing duct 5 are distributed. You may make it provide a separate damper (a 1st damper, a 2nd damper) in the 2 blowing duct 6, respectively. Also in this case, the first damper and the second damper are adjusted according to the control signal from the indoor unit 2a. In addition, it is assumed that a table indicating a correspondence relationship between the target distribution ratio and the opening amounts of the first damper and the second damper is stored in advance in the data storage unit 22 of the indoor unit 2a. The distribution control unit 230 of the indoor unit 2a refers to such a table, determines the opening degree of each of the first damper and the second damper corresponding to the current target distribution ratio, and generates a control signal indicating each determined opening degree. It transmits to each of the first damper and the second damper.
　また、上記実施形態に係る空調システム１は、一般家庭における住居のみならず、オフィスビル、商業ビル等の各種のビルや工場等の空調にも適用可能である。 Further, the air conditioning system 1 according to the above embodiment is applicable not only to residences in ordinary households but also to air conditioning of various buildings and factories such as office buildings and commercial buildings.
　本発明は、本発明の広義の精神と範囲を逸脱することなく、様々な実施形態及び変形が可能とされるものである。また、上述した実施形態は、本発明を説明するためのものであり、本発明の範囲を限定するものではない。つまり、本発明の範囲は、実施形態ではなく、請求の範囲によって示される。そして、請求の範囲内及びそれと同等の発明の意義の範囲内で施される様々な変形が、本発明の範囲内とみなされる。 The present invention is capable of various embodiments and modifications without departing from the broad spirit and scope of the present invention.
