Next, the display on the centralized management device 10 will be described. In the first embodiment, grouping setting is performed for each of the indoor units 30A to 30F. The grouping setting is to set the indoor unit among the indoor units 30A to 30F to be simultaneously operated by the common setting. Specifically, the grouping setting is performed so that the indoor units connected to one remote controller by the remote control transmission line simultaneously operate.
　グルーピング設定を行う場合、１つのグループに対して、同時運転させたい室内ユニットの識別コードが割り当てられる。識別コードとして、例えば、それぞれの室内ユニット３０Ａ～３０Ｆに固有のＭＡＣ（Ｍｅｄｉａ　Ａｃｃｅｓｓ　Ｃｏｎｔｒｏｌ）アドレスまたは論理アドレスが用いられる。 When performing grouping settings, the identification code of the indoor unit you want to operate simultaneously is assigned to one group. As the identification code, for example, a MAC (Media Access Control) address or a logical address unique to each indoor unit 30A to 30F is used.
　図８は、集中管理装置１０の管理側表示部１１のグループ表示例を示す概略図である。図８に示すように、管理側表示部１１には、室内ユニットのグルーピング設定を示すグループ表示領域１１０が設けられている。グループ表示領域１１０には、設定されたグループと、各グループに対して割り当てられた室内ユニットの識別コードが表示される。なお、図８では、説明を容易とするため、識別コードに代えて各室内ユニット３０Ａ～３０Ｆの参照符号が示されている。 FIG. 8 is a schematic diagram showing a group display example of the management-side display unit 11 of the centralized management device 10. As shown in FIG. 8, the management-side display unit 11 is provided with a group display area 110 that indicates grouping settings for indoor units.

［集中管理装置１０における設定表示］
　次に、集中管理装置１０における設定表示について説明する。図９は、集中管理装置１０の管理側表示部１１の設定表示例を示す概略図である。図９に示すように、管理側表示部１１には、グループ毎の各種の設定項目とその設定内容が表示される。この例では、管理側表示部１１には、設定項目を表示する領域として運転状態表示領域１１１、運転モード表示領域１１２、設定温度表示領域１１３および風量表示領域１１４が設けられている。また、この例では、グループ＃１に対応する各種の設定領域が表示されている。 [Setting display in centralized management device 10]
Next, the setting display in the centralized management device 10 will be described. FIG. 9 is a schematic diagram showing a setting display example of the management-side display unit 11 of the centralized management device 10. As shown in FIG. 9, the management-side display unit 11 displays various setting items for each group and their setting contents. In this example, the management-side display unit 11 is provided with an operation state display area 111, an operation mode display area 112, a set temperature display area 113, and an air volume display area 114 as areas for displaying setting items. Further, in this example, various setting areas corresponding to the group #1 are displayed.
　運転状態表示領域１１１は、送信先のグループに対応する室内ユニットの運転状態を表示するために設けられている。運転状態表示領域１１１には、例えば、室内ユニットが運転している状態を示す「ＯＮ」、または運転が停止している状態を示す「ＯＦＦ」が表示される。 The operation status display area 111 is provided to display the operation status of the indoor unit corresponding to the destination group. In the operating state display area 111, for example, "ON" indicating that the indoor unit is operating or "OFF" indicating that the indoor unit is stopped is displayed.
　運転モード表示領域１１２は、送信先のグループに対応する室内ユニットの運転モードを表示するために設けられている。運転モード表示領域１１２には、例えば、暖房運転を示す「暖房」、または冷房運転を示す「冷房」が表示される。 The operation mode display area 112 is provided to display the operation mode of the indoor unit corresponding to the destination group. In the operation mode display area 112, for example, "heating" indicating heating operation or "cooling" indicating cooling operation is displayed.
　設定温度表示領域１１３は、送信先のグループに対応する室内ユニットの設定温度を表示するために設けられている。設定温度表示領域１１３には、例えば、設定温度が２５℃であることを示す「２５℃」が表示される。 The set temperature display area 113 is provided to display the set temperature of the indoor unit corresponding to the destination group. In the set temperature display area 113, for example, “25° C.” indicating that the set temperature is 25° C. is displayed.
　風量表示領域１１４は、送信先のグループに対応する室内ユニットの風量を表示するために設けられている。風量表示領域１１４には、例えば、風量が相対的に強いことを示す「強」、中程度を示す「中」、または相対的に弱いことを示す「弱」が表示される。 The air volume display area 114 is provided to display the air volume of the indoor unit corresponding to the destination group.

（手元リモコン４０Ａ～４０Ｄによる室内ユニット３０Ａ～３０Ｆの設定変更）
　手元リモコン４０Ａ～４０Ｄを操作して室内ユニット３０Ａ～３０Ｆの設定を変更する場合について説明する。ここでは、手元リモコン４０Ａを操作して室内ユニット３０Ａおよび３０Ｂの設定を変更する場合を例にとって説明するが、手元リモコン４０Ｂ～４０Ｄを用いて室内ユニット３０Ｃ～３０Ｆの設定を変更する場合も同様である。 (Change settings of indoor units 30A to 30F by hand remote controllers 40A to 40D)
A case where the local remote controllers 40A to 40D are operated to change the settings of the indoor units 30A to 30F will be described. Here, the case where the local remote controller 40A is operated to change the settings of the indoor units 30A and 30B will be described as an example, but the same applies to the case where the local remote controllers 40B to 40D are used to change the settings of the indoor units 30C to 30F. is there.
　手元リモコン４０Ａを操作して室内ユニット３０Ａおよび３０Ｂの設定を変更する場合、手元リモコン４０Ａの操作者は、リモコン側操作部４２Ａを操作する。リモコン側操作部４２Ａが独立したキー等である場合、操作者は、それぞれの表示領域に対応するキーを操作することにより、キーに対応する設定を変更することができる。また、リモコン側操作部４２Ａがタッチパネルである場合、操作者は、それぞれの表示領域を選択することにより、対応する設定を変更することができる。 When operating the local remote controller 40A to change the settings of the indoor units 30A and 30B, the operator of the local remote controller 40A operates the remote controller side operation unit 42A. When the remote controller side operation unit 42A is an independent key or the like, the operator can change the setting corresponding to the key by operating the key corresponding to each display area. When the remote controller side operation unit 42A is a touch panel, the operator can change the corresponding setting by selecting each display area.
　リモコン側操作部４２Ａが操作された場合、操作に応じた操作信号がリモコン側制御部４５Ａに供給される。リモコン側制御部４５Ａは、受け取った操作信号に基づいて設定を変更するための制御信号を生成する。生成された制御信号は、リモコン側通信部４３Ａおよびリモコン用伝送線４Ａを介して室内ユニット３０Ａおよび３０Ｂに伝送される。そして、制御信号を受信した室内ユニット３０Ａおよび３０Ｂでは、制御信号に含まれる操作者による設定内容に応じて各部が制御される。 When the remote control side operation unit 42A is operated, an operation signal corresponding to the operation is supplied to the remote control side control unit 45A. The remote-control-side control unit 45A generates a control signal for changing the setting based on the received operation signal. The generated control signal is transmitted to the indoor units 30A and 30B via the remote controller side communication unit 43A and the remote controller transmission line 4A. Then, in the indoor units 30A and 30B that have received the control signal, each unit is controlled according to the setting content by the operator included in the control signal.
（集中管理装置１０による室内ユニット３０Ａ～３０Ｆの設定変更）
　集中管理装置１０を操作して室内ユニット３０Ａ～３０Ｆの設定を変更する場合について説明する。ここでは、集中管理装置１０を操作して室内ユニット３０Ａおよび３０Ｂの設定を変更する場合を例にとって説明するが、室内ユニット３０Ｃ～３０Ｆの設定を変更する場合も同様である。 (Changing the settings of the indoor units 30A to 30F by the central control device 10)
A case where the centralized management device 10 is operated to change the settings of the indoor units 30A to 30F will be described. Here, the case where the central management apparatus 10 is operated to change the settings of the indoor units 30A and 30B will be described as an example, but the same applies to the case of changing the settings of the indoor units 30C to 30F.
　集中管理装置１０を操作してグループ＃１に対応する室内ユニット３０Ａおよび３０Ｂの設定を変更する場合、集中管理装置１０の操作者は、管理側操作部１２を操作する。管理側操作部１２が独立したキー等である場合、操作者は、それぞれの表示領域に対応するキーを操作することにより、キーに対応する設定を変更することができる。また、管理側操作部１２がタッチパネルである場合、操作者は、それぞれの表示領域を選択することにより、対応する設定を変更することができる。 When the centralized management device 10 is operated to change the settings of the indoor units 30A and 30B corresponding to the group #1, the operator of the centralized management device 10 operates the management-side operation unit 12. When the management side operation unit 12 is an independent key or the like, the operator can change the setting corresponding to the key by operating the key corresponding to each display area. When the management-side operation unit 12 is a touch panel, the operator can change the corresponding setting by selecting each display area.
　管理側操作部１２が操作された場合、操作に応じた操作信号が管理側制御部１５に供給される。管理側制御部１５は、受け取った操作信号に基づいて設定を変更するための制御信号を生成する。このとき、管理側制御部１５は、管理側記憶部１４に記憶されたグルーピング情報に基づき、制御信号のヘッダー部５１に、グループ＃１にグルーピングされた室内ユニット３０Ａおよび３０Ｂのアドレスを送信先アドレスとして設定する。 When the management side operation unit 12 is operated, an operation signal corresponding to the operation is supplied to the management side control unit 15. The management-side control unit 15 generates a control signal for changing the setting based on the received operation signal. At this time, the management-side control unit 15 sends the addresses of the indoor units 30A and 30B grouped into the group #1 to the destination address in the header section 51 of the control signal based on the grouping information stored in the management-side storage unit 14. Set as.
　生成された制御信号は、管理側通信部１３および伝送線３を介してすべての室内ユニット３０Ａ～３０Ｆに伝送される。制御信号を受信した室内ユニット３０Ａ～３０Ｆは、制御信号のヘッダー部５１に設定された送信先アドレスが自身のアドレスと合致するか否かを判断する。 The generated control signal is transmitted to all the indoor units 30A to 30F via the management-side communication unit 13 and the transmission line 3. Upon receiving the control signal, the indoor units 30A to 30F determine whether the destination address set in the header section 51 of the control signal matches its own address.
　この場合、送信先アドレスとして室内ユニット３０Ａおよび３０Ｂのアドレスが設定されている。室内ユニット３０Ａおよび３０Ｂは、ヘッダー部５１の送信先アドレスが自身のアドレスと合致するため、制御信号に含まれる設定内容に応じて各部を制御する。一方、室内ユニット３０Ｃ～３０Ｆは、送信先アドレスが自身のアドレスと合致しないため、制御信号に含まれる設定内容による制御を行わない。 In this case, the addresses of the indoor units 30A and 30B are set as the destination addresses. The indoor units 30A and 30B control each unit according to the setting content included in the control signal because the destination address of the header unit 51 matches its own address. On the other hand, the indoor units 30C to 30F do not perform control according to the setting content included in the control signal because the destination address does not match their own address.
［グルーピング設定処理］
　空気調和システム１における室内ユニット３０Ａ～３０Ｆのグルーピング設定処理について説明する。図１０は、本実施の形態１に係る空気調和システム１によるグルーピング設定処理の流れの一例を示すフローチャートである。空気調和システム１では、図１０に示すステップＳ１～ステップＳ４の処理が行われることにより、室内ユニット３０Ａ～３０Ｆのグルーピング設定が行われる。 [Grouping setting process]
Grouping setting processing of the indoor units 30A to 30F in the air conditioning system 1 will be described. FIG. 10 is a flowchart showing an example of the flow of grouping setting processing by the air conditioning system 1 according to the first embodiment. In the air conditioning system 1, the grouping setting of the indoor units 30A to 30F is performed by performing the processing of steps S1 to S4 shown in FIG.
（集中管理装置１０による室内ユニット３０Ａ～３０Ｆの設定処理）
　まず、図１０のステップＳ１において、集中管理装置１０は、室内ユニット３０Ａ～３０Ｆの設定処理を行う。ここでは、集中管理装置１０は、空気調和システム１に設けられたすべての室内ユニット３０Ａ～３０Ｆに対して、互いに異なる設定温度を設定する。 (Setting processing of the indoor units 30A to 30F by the central control device 10)
First, in step S1 of FIG. 10, the centralized management device 10 performs setting processing of the indoor units 30A to 30F. Here, the centralized management device 10 sets different set temperatures for all the indoor units 30A to 30F provided in the air conditioning system 1.
　図１１は、図１０のステップＳ１に示す室内ユニット設定処理の流れの一例を示すシーケンス図である。なお、ここでは、説明が容易となるように、空気調和装置２Ａに設けられた室内ユニット３０Ａ～３０Ｃに対する設定処理について説明するが、空気調和装置２Ｂに設けられた室内ユニット３０Ｄ～３０Ｆに対する設定処理についても同様である。また、以下で説明する各処理についても同様とする。 FIG. 11 is a sequence diagram showing an example of the flow of the indoor unit setting process shown in step S1 of FIG. Here, for ease of explanation, the setting process for the indoor units 30A to 30C provided in the air conditioner 2A will be described, but the setting process for the indoor units 30D to 30F provided in the air conditioner 2B will be described. Is also the same. The same applies to each processing described below.
　この設定処理において、集中管理装置１０の管理側制御部１５は、空気調和システム１に設けられた室内ユニット３０Ａ～３０Ｃに対して、互いに異なる設定温度を設定するための制御信号を送信する。具体的には、管理側制御部１５は、シーケンスＳＥＱ１１において、設定温度を２０℃に設定するための制御信号を室内ユニット３０Ａに対して送信する。また、管理側制御部１５は、シーケンスＳＥＱ１２において、設定温度を２１℃に設定するための制御信号を室内ユニット３０Ｂに対して送信する。さらに、管理側制御部１５は、シーケンスＳＥＱ１３において、設定温度を２２℃に設定するための制御信号を室内ユニット３０Ｃに対して送信する。これにより、室内ユニット３０Ａ、３０Ｂおよび３０Ｃでは、それぞれ設定温度が２０℃、２１℃および２２℃に設定される。 In this setting process, the management-side control unit 15 of the centralized management device 10 sends control signals for setting different set temperatures to the indoor units 30A to 30C provided in the air conditioning system 1. Specifically, the management-side control unit 15 transmits a control signal for setting the set temperature to 20° C. to the indoor unit 30A in sequence SEQ11. In addition, the management-side control unit 15 transmits a control signal for setting the set temperature to 21° C. to the indoor unit 30B in sequence SEQ12. Furthermore, the management-side control unit 15 transmits a control signal for setting the set temperature to 22° C. to the indoor unit 30C in sequence SEQ13. As a result, the set temperatures of the indoor units 30A, 30B and 30C are set to 20°C, 21°C and 22°C, respectively.
（手元リモコン４０Ａ～４０Ｄによる室内ユニット３０Ａ～３０Ｆの設定監視および操作処理）
　次に、図１０のステップＳ２において、手元リモコン４０Ａ～４０Ｄは、室内ユニット３０Ａ～３０Ｆの設定監視および操作処理を行う。ここでは、手元リモコン４０Ａ～４０Ｄは、それぞれに接続された室内ユニット３０Ａ～３０Ｆの設定温度を監視し、監視結果に基づき、各手元リモコン４０Ａ～４０Ｄのそれぞれに接続された室内ユニットの設定温度を同一温度に設定する。 (Setting monitoring and operation processing of the indoor units 30A to 30F by the local remote controllers 40A to 40D)
Next, in step S2 of FIG. 10, the local remote controllers 40A to 40D perform setting monitoring and operation processing of the indoor units 30A to 30F. Here, the local remote controllers 40A to 40D monitor the set temperatures of the indoor units 30A to 30F connected to them, and based on the monitoring results, set the temperature of the indoor units connected to the local remote controllers 40A to 40D, respectively. Set to the same temperature.
　図１２は、図１０のステップＳ２に示す室内ユニット３０Ａ～３０Ｃの設定監視および操作処理の流れの一例を示すシーケンス図である。まず、手元リモコン４０Ａは、シーケンスＳＥＱ２１およびシーケンスＳＥＱ２２において、設定温度を要求するための制御信号を、リモコン用伝送線４Ａで接続された室内ユニット３０Ａおよび３０Ｂに対して送信する。 FIG. 12 is a sequence diagram showing an example of the flow of setting monitoring and operation processing of the indoor units 30A to 30C shown in step S2 of FIG. First, the local remote controller 40A transmits a control signal for requesting a set temperature to the indoor units 30A and 30B connected by the remote controller transmission line 4A in sequence SEQ21 and sequence SEQ22.
　室内ユニット３０Ａは、シーケンスＳＥＱ２３において、手元リモコン４０Ａからの要求に対して、設定温度が２０℃であることを示す信号を応答する。また、室内ユニット３０Ｂは、シーケンスＳＥＱ２４において、手元リモコン４０Ａからの要求に対して、設定温度が２１℃であることを示す信号を応答する。 In the sequence SEQ23, the indoor unit 30A responds to the request from the local remote controller 40A with a signal indicating that the set temperature is 20°C. In the sequence SEQ24, the indoor unit 30B responds to the request from the local remote controller 40A with a signal indicating that the set temperature is 21°C.
　次に、手元リモコン４０Ａは、室内ユニット３０Ａおよび３０Ｂからの応答に基づき、２つの設定温度のうちいずれかの設定温度を選択する。この例において、手元リモコン４０Ａは、室内ユニット３０Ｂから受け取った設定温度（２１℃）を選択する。なお、これに限られず、手元リモコン４０Ａは、室内ユニット３０Ａから受け取った設定温度（２０℃）を選択してもよい。 Next, the local remote controller 40A selects one of the two set temperatures based on the responses from the indoor units 30A and 30B. In this example, the local remote controller 40A selects the set temperature (21° C.) received from the indoor unit 30B. Note that the remote controller 40A is not limited to this, and may select the set temperature (20° C.) received from the indoor unit 30A.
　そして、シーケンスＳＥＱ２５およびシーケンスＳＥＱ２６において、手元リモコン４０Ａは、設定温度を２１℃に設定するための制御信号を室内ユニット３０Ａおよび３０Ｂに対して送信する。これにより、室内ユニット３０Ａおよび３０Ｂでは、設定温度が２１℃に設定される。 Then, in sequence SEQ25 and sequence SEQ26, the local remote controller 40A transmits a control signal for setting the set temperature to 21° C. to the indoor units 30A and 30B. As a result, in the indoor units 30A and 30B, the set temperature is set to 21°C.
　一方、手元リモコン４０Ｂは、シーケンスＳＥＱ２７において、設定温度を要求するための制御信号を、リモコン用伝送線４Ｂで接続された室内ユニット３０Ｃに対して送信する。室内ユニット３０Ｃは、シーケンスＳＥＱ２８において、手元リモコン４０Ｂからの要求に対して、設定温度が２２℃であることを示す信号を応答する。 On the other hand, the local remote controller 40B transmits a control signal for requesting the set temperature to the indoor unit 30C connected by the remote controller transmission line 4B in sequence SEQ27. In sequence SEQ28, indoor unit 30C responds to the request from local remote controller 40B with a signal indicating that the set temperature is 22°C.
　次に、手元リモコン４０Ｂは、室内ユニット３０Ｃからの応答に基づき、設定温度を選択する。この場合、手元リモコン４０Ｂには、室内ユニット３０Ｃのみが接続されているため、手元リモコン４０Ｂは、室内ユニット３０Ｃから受け取った設定温度（２２℃）を選択する。 Next, the local remote controller 40B selects the set temperature based on the response from the indoor unit 30C. In this case, since only the indoor unit 30C is connected to the local remote controller 40B, the local remote controller 40B selects the set temperature (22° C.) received from the indoor unit 30C.
　そして、シーケンスＳＥＱ２９において、手元リモコン４０Ｂは、設定温度を２２℃に設定するための制御信号を室内ユニット３０Ｃに対して送信する。これにより、室内ユニット３０Ｃでは、設定温度が２２℃に設定される。 Then, in sequence SEQ29, the local remote controller 40B transmits a control signal for setting the set temperature to 22° C. to the indoor unit 30C. As a result, in the indoor unit 30C, the set temperature is set to 22°C.
　なお、手元リモコン４０Ａ～４０Ｄは、通常、室内ユニット３０Ａ～３０Ｆが設定通りに動作しているか否かの確認を行うために、現在の設定状態を定期的に設定するモードが設けられている。そのため、集中管理装置１０と手元リモコン４０Ａ～４０Ｄとは、伝送線３等で直接接続されていないが、このモードを利用することにより、手元リモコン４０Ａ～４０Ｄは、図１２に示す処理を行うことができる。 Note that the remote controllers 40A to 40D are usually provided with a mode for periodically setting the current setting state in order to confirm whether or not the indoor units 30A to 30F are operating as set. Therefore, the centralized management device 10 and the local remote controllers 40A to 40D are not directly connected by the transmission line 3 or the like, but by using this mode, the local remote controllers 40A to 40D perform the processing shown in FIG.

　具体的には、例えば、図１０のステップＳ１の処理が行われた後、手元リモコン４０Ａ～４０Ｄにおいて上記のモードによる設定確認のタイミングに到達した場合に、手元リモコン４０Ａ～４０Ｄは、各室内ユニット３０Ａ～３０Ｆの設定温度を、図１２のシーケンスＳＥＱ２１～シーケンスＳＥＱ２４で得られた設定温度のうち任意の設定温度に設定し直す。これにより、手元リモコン４０Ａ～４０Ｄは、図１２の処理を行うことができる。 Specifically, for example, after the processing of step S1 of FIG. 10 is performed, when the timing of setting confirmation in the above-mentioned modes is reached in the local remote controllers 40A to 40D, the local remote controllers 40A to 40D are The preset temperatures of 30A to 30F are reset to arbitrary preset temperatures among the preset temperatures obtained in sequence SEQ21 to sequence SEQ24 of FIG. As a result, the local remote controllers 40A to 40D can perform the processing of FIG.
（集中管理装置１０による室内ユニット３０Ａ～３０Ｆの設定監視処理）
　次に、図１０のステップＳ３において、集中管理装置１０は、室内ユニット３０Ａ～３０Ｆの設定監視処理を行う。ここでは、集中管理装置１０は、すべての室内ユニット３０Ａ～３０Ｆの設定温度を監視する。 (Setting monitoring processing of the indoor units 30A to 30F by the central control device 10)
Next, in step S3 of FIG. 10, the centralized management device 10 performs a setting monitoring process for the indoor units 30A to 30F. Here, the centralized management device 10 monitors the set temperatures of all the indoor units 30A to 30F.
　図１３は、図１０のステップＳ３に示す室内ユニット３０Ａ～３０Ｃの設定監視処理の流れの一例を示すシーケンス図である。まず、集中管理装置１０は、シーケンスＳＥＱ３１において、設定温度を要求するための制御信号を、伝送線３で接続された室内ユニット３０Ａに対して送信する。室内ユニット３０Ａは、シーケンスＳＥＱ３２において、集中管理装置１０からの要求に対して、設定温度が２１℃であることを示す信号を応答する。 FIG. 13 is a sequence diagram showing an example of the flow of the setting monitoring process of the indoor units 30A to 30C shown in step S3 of FIG. First, in the sequence SEQ31, the centralized management device 10 transmits a control signal for requesting the set temperature to the indoor unit 30A connected by the transmission line 3. In the sequence SEQ32, the indoor unit 30A responds to the request from the central control device 10 with a signal indicating that the set temperature is 21°C.
　次に、集中管理装置１０は、シーケンスＳＥＱ３３において、設定温度を要求するための制御信号を、伝送線３で接続された室内ユニット３０Ｂに対して送信する。室内ユニット３０Ｂは、シーケンスＳＥＱ３４において、集中管理装置１０からの要求に対して、設定温度が２１℃であることを示す信号を応答する。 Next, in the sequence SEQ33, the central control device 10 transmits a control signal for requesting the set temperature to the indoor unit 30B connected by the transmission line 3. In sequence SEQ34, the indoor unit 30B responds to the request from the central control device 10 with a signal indicating that the set temperature is 21°C.
　次に、集中管理装置１０は、シーケンスＳＥＱ３５において、設定温度を要求するための制御信号を、伝送線３で接続された室内ユニット３０Ｃに対して送信する。室内ユニット３０Ｃは、シーケンスＳＥＱ３６において、集中管理装置１０からの要求に対して、設定温度が２２℃であることを示す信号を応答する。 Next, in the sequence SEQ35, the central control device 10 transmits a control signal for requesting the set temperature to the indoor unit 30C connected by the transmission line 3. In the sequence SEQ36, the indoor unit 30C responds to the request from the central control device 10 with a signal indicating that the set temperature is 22°C.
（集中管理装置１０による室内ユニット３０Ａ～３０Ｆのグルーピング処理）
　次に、図１０のステップＳ４において、集中管理装置１０は、室内ユニット３０Ａ～３０Ｆのグルーピング処理を行う。ここでは、集中管理装置１０は、それぞれの室内ユニット３０Ａ～３０Ｆから受け取った設定温度に基づき、同一の設定温度に設定された室内ユニットを同一グループとするグルーピング処理を行う。 (Grouping processing of the indoor units 30A to 30F by the central control device 10)
Next, in step S4 of FIG. 10, the centralized management device 10 performs a grouping process of the indoor units 30A to 30F. Here, the centralized management device 10 performs a grouping process in which the indoor units set to the same set temperature are set to the same group based on the set temperatures received from the respective indoor units 30A to 30F.
　図１４は、図１０のステップＳ４に示す室内ユニット３０Ａ～３０Ｆのグルーピング処理について説明するための概略図である。集中管理装置１０は、図１３に示す処理により受け取ったそれぞれの室内ユニット３０Ａ～３０Ｆの設定温度を、例えば表形式で管理側記憶部１４に保存する。そして、集中管理装置１０は、保存した設定温度に基づき、同一の設定温度に設定された室内ユニットが、同一のリモコン用伝送線で接続されていると判断し、同一のグループに設定する。 FIG. 14 is a schematic diagram for explaining the grouping processing of the indoor units 30A to 30F shown in step S4 of FIG. The centralized management device 10 stores the set temperatures of the respective indoor units 30A to 30F received by the processing shown in FIG. 13 in the management-side storage unit 14 in, for example, a table format. Then, the central control device 10 determines that the indoor units set to the same set temperature are connected by the same remote control transmission line based on the stored set temperature, and sets them in the same group.
　この例において、室内ユニット３０Ａおよび３０Ｂは、同一の設定温度（２１℃）に設定されているため、同一グループ＃１としてグルーピングされる。また、室内ユニット３０Ｃは、単一の設定温度（２２℃）に設定されているため、グループ＃２としてグルーピングされる。 In this example, since the indoor units 30A and 30B are set to the same set temperature (21°C), they are grouped as the same group #1. Further, the indoor unit 30C is set to a single set temperature (22° C.), and thus is grouped as a group #2.
　室内ユニット３０Ｄおよび３０Ｅは、同一の設定温度（２３℃）に設定されているため、同一グループ＃３としてグルーピングされる。室内ユニット３０Ｆは、単一の設定温度（２５℃）に設定されているため、グループ＃４としてグルーピングされる。 Since the indoor units 30D and 30E are set to the same set temperature (23°C), they are grouped as the same group #3. Since the indoor unit 30F is set to a single set temperature (25° C.), it is grouped as a group #4.
　このように、図１０に示すステップＳ１～ステップＳ４のグルーピング設定処理により、集中管理装置１０は、室内ユニット３０Ａ～３０Ｆと手元リモコン４０Ａ～４０Ｄとの接続関係が不明である場合でも、接続関係を自動的に判断してグルーピング設定を行うことができる。 In this way, by the grouping setting process of steps S1 to S4 shown in FIG. 10, the centralized management device 10 establishes the connection relationship even if the connection relationship between the indoor units 30A to 30F and the local remote controllers 40A to 40D is unknown. It is possible to automatically judge and set the grouping.
　なお、操作者が手元リモコン４０Ａ～４０Ｄを操作し、それぞれの手元リモコン４０Ａ～４０Ｄに対応する室内ユニット３０Ａ～３０Ｆの設定温度を設定する場合には、図１１に示す処理を省略してもよい。 When the operator operates the local remote controllers 40A to 40D and sets the set temperatures of the indoor units 30A to 30F corresponding to the local remote controllers 40A to 40D, the process shown in FIG. 11 may be omitted. ..
　また、室内ユニットの台数が多く、それぞれの室内ユニットに対して異なる設定温度を設定することが困難である場合には、設定温度、設定風量、運転モードおよび運転状態等の２種類以上のパラメータを組み合わせて設定してもよい。 In addition, when the number of indoor units is large and it is difficult to set different set temperatures for each indoor unit, set two or more types of parameters such as set temperature, set air volume, operation mode, and operation state. You may set up in combination.
　図１５は、図１０のステップＳ１に示す室内ユニット設定処理の流れの他の例を示すシーケンス図である。この例では、それぞれの室内ユニット３０Ａ～３０Ｃに対して、設定温度に加えて風量が設定される。また、この場合には、設定温度と設定風量との組み合わせが、それぞれの室内ユニット３０Ａ～３０Ｃに対して異なるように設定される。 FIG. 15 is a sequence diagram showing another example of the flow of the indoor unit setting process shown in step S1 of FIG. In this example, in addition to the set temperature, the air volume is set for each of the indoor units 30A to 30C. Further, in this case, the combination of the set temperature and the set air volume is set to be different for each indoor unit 30A to 30C.
　集中管理装置１０の管理側制御部１５は、空気調和システム１に設けられた室内ユニット３０Ａ～３０Ｃに対して、互いに異なる設定温度および設定風量の組み合わせを設定するための制御信号を送信する。具体的には、管理側制御部１５は、シーケンスＳＥＱ１０１において、設定温度を２０℃に設定するための制御信号を室内ユニット３０Ａに対して送信する。また、管理側制御部１５は、シーケンスＳＥＱ１０２において、設定風量を「強」に設定するための制御信号を室内ユニット３０Ａに対して送信する。 The management-side control unit 15 of the centralized management device 10 transmits control signals for setting different combinations of set temperatures and set air volumes to the indoor units 30A to 30C provided in the air conditioning system 1. Specifically, the management-side control unit 15 transmits a control signal for setting the set temperature to 20° C. to the indoor unit 30A in sequence SEQ101. Further, the management-side control unit 15 transmits a control signal for setting the set air volume to "strong" to the indoor unit 30A in sequence SEQ102.
　次に、管理側制御部１５は、シーケンスＳＥＱ１０３において、設定温度を２０℃に設定するための制御信号を室内ユニット３０Ｂに対して送信する。また、管理側制御部１５は、シーケンスＳＥＱ１０４において、設定風量を「弱」に設定するための制御信号を室内ユニット３０Ｂに対して送信する。 Next, the management-side control unit 15 transmits a control signal for setting the set temperature to 20° C. to the indoor unit 30B in sequence SEQ103. In addition, the management-side control unit 15 transmits a control signal for setting the set air volume to "weak" to the indoor unit 30B in sequence SEQ104.
　さらに、管理側制御部１５は、シーケンスＳＥＱ１０５において、設定温度を２１℃に設定するための制御信号を室内ユニット３０Ｃに対して送信する。また、管理側制御部１５は、シーケンスＳＥＱ１０６において、設定風量を「強」に設定するための制御信号を室内ユニット３０Ｃに対して送信する。 Furthermore, the management-side control unit 15 transmits a control signal for setting the set temperature to 21° C. to the indoor unit 30C in sequence SEQ105. In addition, the management-side control unit 15 transmits a control signal for setting the set air volume to “strong” to the indoor unit 30C in sequence SEQ106.
　これにより、室内ユニット３０Ａでは、設定温度が２０℃に設定されるとともに、設定風量が「強」に設定される。室内ユニット３０Ｂでは、設定温度が２０℃に設定されるとともに、設定風量が「弱」に設定される。室内ユニット３０Ｃでは、設定温度が２１℃に設定されるとともに、設定風量が「強」に設定される。 With this, in the indoor unit 30A, the set temperature is set to 20° C. and the set air volume is set to “strong”. In the indoor unit 30B, the set temperature is set to 20°C and the set air volume is set to "weak". In the indoor unit 30C, the set temperature is set to 21° C. and the set air volume is set to “strong”.
　以上のように、本実施の形態１に係る空気調和システムでは、手元リモコンに接続された室内ユニットに対して同一値の設定項目が設定され、集中管理装置は、同一値の設定項目が設定された室内ユニットが同一の手元リモコンに接続されていると判断する。そして、集中管理装置は、同一の手元リモコンに接続された室内ユニットを同一のグループに設定する。これにより、電気配線図を用いることなく、集中管理装置でリモコンと複数の室内ユニットとの接続関係を判断し、連動する複数の室内ユニットを設定することができる。 As described above, in the air conditioning system according to the first embodiment, the setting items having the same value are set for the indoor unit connected to the local remote controller, and the setting items having the same value are set for the central control device. It is determined that the indoor units are connected to the same local remote controller. Then, the central control device sets the indoor units connected to the same remote controller in the same group. Thus, the central management device can determine the connection relationship between the remote controller and the plurality of indoor units and set a plurality of interlocking indoor units without using the electrical wiring diagram.
　本実施の形態１に係る空気調和システムにおいて、集中管理装置は、すべての室内ユニットに対して異なる設定項目の値を設定する。また、手元リモコンは、接続された室内ユニットに対して設定された設定項目の値から任意の値を選択し、接続された室内ユニットのすべてに対して選択した値を設定する。これにより、手元リモコンによる設定項目の設定が自動的になされるため、連動する複数の室内ユニットをより容易に設定することができる。 In the air conditioning system according to Embodiment 1, the central control device sets different setting item values for all indoor units. Further, the local remote controller selects an arbitrary value from the values of the setting items set for the connected indoor units, and sets the selected value for all the connected indoor units. As a result, since the setting items are automatically set by the remote controller at hand, a plurality of interlocking indoor units can be set more easily.
　本実施の形態１に係る空気調和システムにおいて、設定項目は、室内ユニットに対する設定温度とする。これにより、空気調和システムに多数の室内ユニットが設けられた場合でも、異なる温度を設定することができる。 In the air conditioning system according to the first embodiment, the setting item is the set temperature for the indoor unit. Thereby, even when a large number of indoor units are provided in the air conditioning system, different temperatures can be set.
