In addition, the heating capacity + defrosting capacity shared by the heat source unit 1a performing the defrosting operation is distributed to the other heat source units 1b or 1c. Specifically, when there are the heat source units 1b and 1c whose operation mode in the heat source side information is the heating operation and the heat source unit 1a whose operation mode is the defrosting operation, the control information generation unit 85 calculates the total operation capacity. Then, the operation capability for control is obtained by apportioning to the heat source devices 1b and 1c whose operation mode is the heating operation.
　なお、制御用運転能力の算出方法は、上記に限定されるものではない。例えば、合計運転能力を、複数の熱源機１ａ～１ｃに均等に配分してもよい。また、各熱源機１ａ～１ｃの熱交換容量などに応じた比率で、合計運転能力を按分してもよい。また、各熱源機１ａ～１ｃの圧縮機１０の運転時間に応じて、合計運転能力を按分してもよい。この場合、圧縮機１０の運転時間が長い熱源機の配分を少なくする、または運転を停止すればよい。また、任意に設定した重み付け係数などに応じて、合計運転能力を按分してもよい。制御情報生成部８５によって生成された熱源機１ａ～１ｃ毎の制御用運転能力は、制御情報として通信部８１を介して各熱源機１ａ～１ｃの熱源側制御装置５０に送信される。 In addition, the calculation method of the driving ability for control is not limited to the above. For example, the total operating capacity may be evenly distributed to the plurality of heat source units 1a to 1c. Further, the total operation capacity may be prorated according to the ratio according to the heat exchange capacity of each of the heat source units 1a to 1c. Further, the total operation capacity may be prorated according to the operation time of the compressor 10 of each of the heat source units 1a to 1c. In this case, the distribution of the heat source unit having a long operation time of the compressor 10 may be reduced or the operation may be stopped. Further, the total driving ability may be prorated according to an arbitrarily set weighting coefficient or the like. The control operation capacity for each heat source unit 1a to 1c generated by the control information generation unit 85 is transmitted as control information to the heat source side control device 50 of each heat source unit 1a to 1c via the communication unit 81.

FIG. 6 is a flowchart for explaining the operation of the usage-side unit 3a. The other usage side units 3b to 3f perform the same operation as the usage side unit 3a. First, the communication unit 61 determines whether instruction information has been received from the remote controller 7a (S11). Here, when the instruction information is not received from the remote controller 7a (S11: NO), it waits until it is received. On the other hand, when the instruction information is received from the remote controller 7a (S11: YES), the instruction information is transmitted to the control unit 62. Then, the control unit 62 performs air volume control of the blower 31 and opening / closing control of the on-off valve 4a according to the instruction information (S12). Then, the usage side information of the current usage side unit 3a is acquired by the information acquisition unit 63 and transmitted to the integrated management apparatus 8 via the communication unit 61 (S13).
［統合管理装置８］
　図７は、統合管理装置８の動作を説明するフローチャートである。まず、通信部８１にて、熱源機１ａ～１ｃの熱源側制御装置５０から熱源側情報を受信したか否かが判断される（Ｓ２１）。ここで、熱源機１ａ～１ｃの熱源側制御装置５０から熱源側情報を受信していない場合は（Ｓ２１：ＮＯ）、ステップＳ２３へ進む。一方、熱源機１ａ～１ｃの熱源側制御装置５０から熱源側情報を受信した場合は（Ｓ２１：ＹＥＳ）、更新部８３によって、記憶部８２に記憶される熱源機１ａ～１ｃの熱源側情報のうち、送信元の熱源機の熱源側情報が更新される（Ｓ２２）。 [Integrated management device 8]
FIG. 7 is a flowchart for explaining the operation of the integrated management apparatus 8. First, the communication unit 81 determines whether or not heat source side information has been received from the heat source side control device 50 of the heat source machines 1a to 1c (S21). Here, when the heat source side information is not received from the heat source side control device 50 of the heat source units 1a to 1c (S21: NO), the process proceeds to step S23. On the other hand, when the heat source side information is received from the heat source side control device 50 of the heat source units 1a to 1c (S21: YES), the update unit 83 stores the heat source side information of the heat source units 1a to 1c stored in the storage unit 82. Among them, the heat source side information of the transmission source heat source machine is updated (S22).
　続いて、通信部８１にて、利用側ユニット３ａ～３ｆの利用側制御装置６０から利用側情報を受信したか否かが判断される（Ｓ２３）。ここで、利用側ユニット３ａ～３ｆの利用側制御装置６０から利用側情報を受信していない場合は（Ｓ２３：ＮＯ）、ステップＳ２１に戻る。一方、利用側ユニット３ａ～３ｆの利用側制御装置６０から利用側情報を受信した場合は（Ｓ２３：ＹＥＳ）、更新部８３によって、記憶部８２に記憶される利用側ユニット３ａ～３ｆの利用側情報のうち、送信元の利用側ユニットの利用側情報が更新される（Ｓ２４）。 Subsequently, the communication unit 81 determines whether or not usage side information has been received from the usage side control device 60 of the usage side units 3a to 3f (S23). Here, when the usage side information is not received from the usage side control device 60 of the usage side units 3a to 3f (S23: NO), the process returns to step S21. On the other hand, when the usage side information is received from the usage side control device 60 of the usage side units 3a to 3f (S23: YES), the usage side of the usage side units 3a to 3f stored in the storage unit 82 by the updating unit 83 is used. Of the information, the usage-side information of the transmission-side usage-side unit is updated (S24).
　次に、能力算出部８４によって、記憶部８２に記憶される複数の利用側ユニット３ａ～３ｆの利用側情報に基づき、複数の利用側ユニット３ａ～３ｆのうち、動作状態が運転状態である利用側ユニットの運転能力の合計値である合計運転能力が算出される（Ｓ２５）。そして、制御情報生成部８５によって、合計運転能力および記憶部８２に記憶される複数の熱源機１ａ～１ｃの熱源側情報に基づき、制御情報として、各熱源機１ａ～１ｃの制御用運転能力が算出される（Ｓ２６）。そして、通信部８１から各熱源機１ａ～１ｃの熱源側制御装置５０に対して制御情報が送信され（Ｓ２７）、ステップＳ２１に戻る。 Next, based on the use side information of the plurality of use side units 3a to 3f stored in the storage unit 82 by the ability calculation unit 84, the use state in which the operation state is the driving state among the plurality of use side units 3a to 3f. A total driving ability which is a total value of the driving ability of the side unit is calculated (S25). Then, based on the total operating capacity and the heat source side information of the plurality of heat source apparatuses 1a to 1c stored in the storage unit 82 by the control information generation unit 85, the control operating capacity of each heat source apparatus 1a to 1c is determined as control information. Calculated (S26). Then, control information is transmitted from the communication unit 81 to the heat source side control devices 50 of the heat source devices 1a to 1c (S27), and the process returns to step S21.
　［熱源機１ａ～１ｃ］
　図８は、熱源機１ａの動作を説明するフローチャートである。その他の熱源機１ｂおよび１ｃは、熱源機１ａと同様の動作を行う。まず、通信部５１にて、統合管理装置８から制御情報を受信したか否かが判断される（Ｓ３１）。ここで、統合管理装置８から制御情報を受信していない場合は（Ｓ３１：ＮＯ）、受信するまで待機する。一方、統合管理装置８から制御情報を受信した場合は（Ｓ３１：ＹＥＳ）、制御部５２によって、制御情報に応じて、圧縮機１０の運転容量制御、送風機１５の送風量制御、およびポンプ２ａの回転数制御などが実施され（Ｓ３２）、ステップＳ３１へ戻る。 [Heat source machines 1a to 1c]
FIG. 8 is a flowchart for explaining the operation of the heat source device 1a. The other heat source units 1b and 1c perform the same operation as the heat source unit 1a. First, the communication unit 51 determines whether control information has been received from the integrated management device 8 (S31). Here, when control information is not received from the integrated management apparatus 8 (S31: NO), it waits until it receives. On the other hand, when the control information is received from the integrated management device 8 (S31: YES), the control unit 52 controls the operation capacity of the compressor 10, the air flow control of the blower 15, and the pump 2a according to the control information. The rotational speed control and the like are performed (S32), and the process returns to step S31.
　また、上記処理と並行して、情報取得部５３によって、熱源機１ａの熱源側情報が取得され、通信部５１を介して統合管理装置８に送信される（Ｓ３３）。そして、予め設定された時間だけ休止を行い（Ｓ３４）、ステップＳ３３に戻る。なお、ここでは、定期的に熱源側情報を送信する流れとなっているが、熱源機１ａの動作状態が変化した場合にのみ熱源側情報を送信してもよい。 In parallel with the above processing, the information acquisition unit 53 acquires the heat source side information of the heat source device 1a and transmits it to the integrated management apparatus 8 via the communication unit 51 (S33). Then, a pause is performed for a preset time (S34), and the process returns to step S33. In addition, although it is the flow which transmits heat source side information regularly here, you may transmit heat source side information only when the operation state of the heat source machine 1a changes.
　以上のように、本実施の形態の空気調和装置１００では、熱源機１ａ～１ｃおよび利用側ユニット３ａ～３ｆにそれぞれ熱源側制御装置５０および利用側制御装置６０を設置し、各部の制御を行うとともに、統合管理装置８で、複数の利用側ユニット３ａ～３ｆの動作状態に応じて、自動的に熱源機１ａ～１ｃの運転制御を行う構成となっている。また、複数の熱源機１ａ～１ｃおよび利用側ユニット３ａ～３ｆは、それぞれ同一の一対の２次側熱媒体配管５に並列に接続される構成となっている。これにより、空気調和装置１００の熱源機１ａ～１ｃおよび利用側ユニット３ａ～３ｆの接続台数にかかわらず、リモートコントローラー７ａ～７ｆ、熱源側制御装置５０、利用側制御装置６０および統合管理装置８において同じ制御を行うことができ、空気調和装置の構成に応じて統合管理装置８の制御プログラムを個別に変更するといった煩雑な設定を行う必要がない。また、複数の熱源機１ａ～１ｃと複数の利用側ユニット３ａ～３ｆとを対応付ける必要もないため、各機器のアドレス設定にも制約を設ける必要がない。 As described above, in the air conditioner 100 of the present embodiment, the heat source side control device 50 and the use side control device 60 are installed in the heat source units 1a to 1c and the use side units 3a to 3f, respectively, and control of each part is performed. At the same time, the integrated management device 8 is configured to automatically control the operation of the heat source units 1a to 1c in accordance with the operating states of the plurality of use side units 3a to 3f. The plurality of heat source units 1a to 1c and the use side units 3a to 3f are connected in parallel to the same pair of secondary side heat medium pipes 5, respectively. Accordingly, in the remote controllers 7a to 7f, the heat source side control device 50, the usage side control device 60, and the integrated management device 8, regardless of the number of connected heat source devices 1a to 1c and usage side units 3a to 3f of the air conditioner 100. The same control can be performed, and there is no need to perform complicated settings such as individually changing the control program of the integrated management device 8 according to the configuration of the air conditioner. In addition, since it is not necessary to associate the plurality of heat source units 1a to 1c with the plurality of use side units 3a to 3f, it is not necessary to set restrictions on the address setting of each device.
　また、熱源側制御装置５０および利用側制御装置６０において熱源機１ａ～１ｃおよび利用側ユニット３ａ～３ｆの制御をそれぞれ行うことで、従来の直膨式の空気調和装置と同様のシステム設計が容易に実現できる。また、直膨式の空気調和装置に対応するよう開発されたリモートコントローラーおよび集中管理装置などの部材の共用化および有効利用も可能になり、さらにファンコイル方式と直膨方式の混在システムの構築も容易になる。また、熱源側制御装置５０および利用側制御装置６０を活用することにより、熱源機および利用側ユニットの選定の自由度が向上し、物件に合わせた特殊な形状また能力の機器を組み合わせることも容易となる。 In addition, by controlling the heat source units 1a to 1c and the use side units 3a to 3f in the heat source side control device 50 and the use side control device 60, respectively, it is easy to design a system similar to a conventional direct expansion type air conditioner. Can be realized. It is also possible to share and effectively use components such as remote controllers and centralized control devices that have been developed to support direct expansion type air conditioners, and to construct a mixed system of fan coil type and direct expansion type. It becomes easy. Further, by utilizing the heat source side control device 50 and the use side control device 60, the degree of freedom of selection of the heat source unit and the use side unit is improved, and it is easy to combine a device having a special shape or ability according to the property. It becomes.
　また、従来の複数の熱源機および複数の利用側ユニットを備えた空気調和装置においては、複数の利用側ユニットの動作状態によって、熱源機に必要となる運転能力が変化する場合がある。このような場合、複数の熱源機の運転能力にアンバランスが生じ、システム全体としてのシステム効率が低下する、という問題点があった。これに対し、本実施の形態の空気調和装置１００では、統合管理装置８によって複数の熱源機１ａ～１ｃを連携制御することで効率良く熱源機１ａ～１ｃを運転することができる。さらに、熱源機１ａ～１ｃの熱源側情報に基づいて制御情報を生成することで、除霜運転などの空調能力が変動する運転における利用側ユニット３ａ～３ｆへの影響を抑制することもできる。 Also, in an air conditioner equipped with a plurality of conventional heat source units and a plurality of usage side units, the operating capacity required for the heat source unit may vary depending on the operating state of the plurality of usage side units. In such a case, there has been a problem that the operation efficiency of the plurality of heat source units is unbalanced, and the system efficiency of the entire system is lowered. On the other hand, in the air conditioning apparatus 100 of the present embodiment, the heat source apparatuses 1a to 1c can be efficiently operated by cooperatively controlling the plurality of heat source apparatuses 1a to 1c by the integrated management apparatus 8. Furthermore, by generating the control information based on the heat source side information of the heat source units 1a to 1c, it is possible to suppress the influence on the use side units 3a to 3f in the operation in which the air conditioning capability fluctuates such as the defrosting operation.

The control information generation unit 505 that generates control information of the heat source units 1a to 1c from the total operating capacity, the control unit 506 that controls each unit of the heat source unit 1a, and the information acquisition unit 507 that acquires the heat source side information of the heat source unit 1a And having. Each of the above units is realized by executing a program by a CPU constituting the heat source side control device 500 as a functional unit realized by software, or realized by an electronic circuit such as a DSP, ASIC, or PLD.
　通信部５０１は、熱源機１ｂおよび１ｃの熱源側情報、ならびに利用側ユニット３ａ～３ｆの利用側情報を受信する。記憶部５０２は、例えば不揮発性メモリであり、情報取得部５０７によって取得された熱源機１ａの熱源側情報、通信部５０１を介して受信した熱源機１ｂおよび１ｃの熱源側情報ならびに利用側ユニット３ａ～３ｆの利用側情報を、送信元の熱源機１ａ～１ｃおよび利用側ユニット３ａ～３ｆとそれぞれ関連付けて記憶する。更新部５０３は、熱源機１ａ～１ｃおよび利用側ユニット３ａ～３ｆから熱源側情報および利用側情報を新たに受信した場合、記憶部５０２に記憶される熱源側情報および利用側情報を更新する。 The communication unit 501 receives the heat source side information of the heat source devices 1b and 1c and the usage side information of the usage side units 3a to 3f. The storage unit 502 is, for example, a nonvolatile memory, the heat source side information of the heat source unit 1a acquired by the information acquisition unit 507, the heat source side information of the heat source units 1b and 1c received via the communication unit 501, and the usage side unit 3a. ˜3f usage side information is stored in association with the transmission source heat source units 1a to 1c and the usage side units 3a to 3f, respectively. The update unit 503 updates the heat source side information and the use side information stored in the storage unit 502 when newly receiving the heat source side information and the use side information from the heat source devices 1a to 1c and the use side units 3a to 3f.
　能力算出部５０４は、記憶部５０２に記憶される複数の利用側ユニット３ａ～３ｆの利用側情報に基づき、複数の利用側ユニット３ａ～３ｆのうち、動作状態が運転状態である利用側ユニットの運転能力の合計値である合計運転能力を算出する。制御情報生成部５０５は、能力算出部５０４にて算出された合計運転能力および記憶部５０２に記憶される複数の熱源機１ａ～１ｃの熱源側情報に基づき、制御情報として、各熱源機１ａ～１ｃの制御用運転能力を算出する。本実施の形態において、空気調和装置１００Ａを構成する全ての熱源機１ａ～１ｃは、同じアルゴリズムで制御情報（制御用運転能力）を生成する。制御情報生成部５０５における制御用運転能力の算出方法は、実施の形態１の制御情報生成部８５と同様である。 Based on the usage side information of the plurality of usage side units 3a to 3f stored in the storage unit 502, the capability calculation unit 504 selects the usage side unit of the usage side unit 3a to 3f whose operating state is the operating state. The total driving ability, which is the total value of the driving ability, is calculated. The control information generation unit 505 uses the total operating capacity calculated by the capacity calculation unit 504 and the heat source side information of the plurality of heat source units 1a to 1c stored in the storage unit 502 as control information. The control driving ability of 1c is calculated. In the present embodiment, all of the heat source units 1a to 1c constituting the air conditioning apparatus 100A generate control information (control driving capability) using the same algorithm.

The heat source side information includes the operation or stop state of the heat source unit 1a, the operation mode (heating, cooling or defrosting), the heat exchange capacity, the operation time of the compressor 10, and the like. The heat source side information acquired by the information acquisition unit 507 is stored in the storage unit 502 and transmitted from the communication unit 501 to addresses indicating all devices that are constituent elements of the air conditioning apparatus 100A. Here, the purpose of transmitting to the addresses indicating all devices is to transmit the heat source side information to the heat source side control devices 500 of the other heat source machines 1b and 1c. Therefore, it is not limited to transmitting to addresses indicating all devices, and may be transmitted by a method that can be received by the heat source side control devices 500 of the heat source devices 1b and 1c. For example, you may transmit with respect to the address which shows all the heat source side control apparatuses 500 defined beforehand. Further, instead of defining addresses indicating all devices or all heat source side control devices 500 in advance, they may be individually transmitted to all devices or individually transmitted to all heat source side control devices 500. May be. Further, the transmission destination may not be an address indicating the heat source side control device 500 as long as the heat source side control device 500 can acquire data addressed to other devices flowing through the communication line.

[Remote controllers 7a-7f]
The operations of the remote controllers 7a to 7f of the present embodiment are the same as the operations of the first embodiment shown in FIG.
［利用側ユニット３ａ～３ｆ］
　本実施の形態の利用側ユニット３ａ～３ｆの動作は、以下の点を除いて図６に示す実施の形態２の動作と同様である。実施の形態１では、図６のステップＳ１３において、現在の利用側ユニットの利用側情報が統合管理装置８に送信されるが、本実施の形態では、予め定義されている空気調和装置１００Ａの構成要素である全ての機器を示すアドレスに対して送信される。ここで、全ての機器を示すアドレスに対して送信する目的は、全ての熱源機１ａ～１ｃの熱源側制御装置５００へ動作状態情報を送信するためである。そのため、全ての機器を示すアドレスに対して送信することに限定されず、熱源機１ａ～１ｃの熱源側制御装置５００が受信できる方式で送信されればよい。具体的な方法は、熱源側情報の送信について述べた通りである。 [Use side units 3a to 3f]
The operations of the use side units 3a to 3f of the present embodiment are the same as those of the second embodiment shown in FIG. 6 except for the following points. In the first embodiment, in step S13 of FIG. 6, the usage side information of the current usage side unit is transmitted to the integrated management device 8, but in this embodiment, the configuration of the air conditioner 100A defined in advance Sent to an address indicating all devices as elements. Here, the purpose of transmitting to the addresses indicating all devices is to transmit the operation state information to the heat source side control devices 500 of all the heat source machines 1a to 1c. Therefore, the transmission is not limited to the address indicating all devices, and may be transmitted by a method that can be received by the heat source side control device 500 of the heat source devices 1a to 1c. The specific method is as described for the transmission of the heat source side information.
［熱源機１ａ～１ｃ］
　図１０は、本実施の形態における熱源機１ａの動作を説明するフローチャートである。その他の熱源機１ｂおよび１ｃは、熱源機１ａと同様の動作を行う。まず、通信部５０１にて、自身を含む熱源機１ａ～１ｃの熱源側制御装置５００から熱源側情報を受信したか否かが判断される（Ｓ４１）。ここで、熱源機１ａ～１ｃから熱源側情報を受信していない場合は（Ｓ４１：ＮＯ）、ステップＳ４３へ進む。一方、熱源機１ａ～１ｃから熱源側情報を受信した場合は（Ｓ４１：ＹＥＳ）、更新部５０３によって、記憶部５０２に記憶される熱源機１ａ～１ｃの熱源側情報のうち、送信元の熱源機の熱源側情報が更新される（Ｓ４２）。 [Heat source machines 1a to 1c]
FIG. 10 is a flowchart for explaining the operation of the heat source device 1a in the present embodiment. The other heat source units 1b and 1c perform the same operation as the heat source unit 1a. First, the communication unit 501 determines whether or not heat source side information has been received from the heat source side control device 500 of the heat source machines 1a to 1c including itself (S41). Here, when the heat source side information is not received from the heat source machines 1a to 1c (S41: NO), the process proceeds to step S43. On the other hand, when the heat source side information is received from the heat source units 1a to 1c (S41: YES), the update unit 503 among the heat source side information of the heat source units 1a to 1c stored in the storage unit 502 is the source heat source The heat source side information of the machine is updated (S42).
　続いて、通信部５０１にて、利用側ユニット３ａ～３ｆの利用側制御装置６０から利用側情報を受信したか否かが判断される（Ｓ４３）。ここで、利用側ユニット３ａ～３ｆの利用側制御装置６０から利用側情報を受信していない場合は（Ｓ４３：ＮＯ）、ステップＳ４１に戻る。一方、利用側ユニット３ａ～３ｆの利用側制御装置６０から利用側情報を受信した場合は（Ｓ４３：ＹＥＳ）、更新部５０３によって、記憶部５０２に記憶される利用側ユニット３ａ～３ｆの利用側情報のうち、送信元の利用側ユニットの利用側情報が更新される（Ｓ４４）。 Subsequently, the communication unit 501 determines whether usage side information has been received from the usage side control device 60 of the usage side units 3a to 3f (S43). Here, when the usage side information is not received from the usage side control device 60 of the usage side units 3a to 3f (S43: NO), the process returns to step S41. On the other hand, when the usage side information is received from the usage side control device 60 of the usage side units 3a to 3f (S43: YES), the usage side of the usage side units 3a to 3f stored in the storage unit 502 by the updating unit 503 is used. Of the information, the usage-side information of the transmission-side usage-side unit is updated (S44).
　次に、能力算出部５０４によって、記憶部５０２に記憶される複数の利用側ユニット３ａ～３ｆの利用側情報に基づき、複数の利用側ユニット３ａ～３ｆのうち、動作状態が運転状態である利用側ユニットの運転能力の合計値である合計運転能力が算出される（Ｓ４５）。そして、制御情報生成部５０５によって、合計運転能力および記憶部５０２に記憶される複数の熱源機１ａ～１ｃの熱源側情報に基づき、制御情報として、熱源機１ａ～１ｃ毎の制御用運転能力が算出される（Ｓ４６）。そして、制御部５０６によって、生成された制御情報に基づいて、圧縮機１０の運転容量制御、送風機１５の送風量制御、およびポンプ２ａの回転数制御などが実施され（Ｓ４７）、ステップＳ４１に戻る。 Next, based on the usage side information of the plurality of usage side units 3a to 3f stored in the storage unit 502 by the capability calculation unit 504, the usage state in which the operation state is the operating state among the plurality of usage side units 3a to 3f. A total driving ability which is a total value of the driving ability of the side unit is calculated (S45). Based on the total operating capacity and the heat source side information of the plurality of heat source units 1a to 1c stored in the storage unit 502 by the control information generation unit 505, the control operating capacity for each of the heat source units 1a to 1c is obtained as control information. Calculated (S46). Then, based on the generated control information, the control unit 506 performs the operation capacity control of the compressor 10, the air volume control of the blower 15, the rotational speed control of the pump 2a, and the like (S47), and returns to step S41. .
　また、上記の処理と並行して、情報取得部５０７によって、熱源機１ａの熱源側情報が取得され、通信部５０１を介して送信される（Ｓ４８）。そして、予め設定された時間だけ休止を行い（Ｓ４９）、ステップＳ４８に戻る。なお、ここでは、定期的に熱源側情報を送信する流れとなっているが、熱源機１ａの動作状態が変化した場合にのみ熱源側情報を送信してもよい。 In parallel with the above processing, the information acquisition unit 507 acquires the heat source side information of the heat source unit 1a and transmits the information via the communication unit 501 (S48). Then, a pause is performed for a preset time (S49), and the process returns to step S48. In addition, although it is the flow which transmits heat source side information regularly here, you may transmit heat source side information only when the operation state of the heat source machine 1a changes.
　以上のように、本実施の形態においては、各熱源機１ａ～１ｃには、全ての利用側制御装置６０および熱源側制御装置５００から、算出に必要な熱源側情報および利用側情報が送信されるため、各熱源機１ａ～１ｃに対する制御用能力の算出結果は同じになる。そのため、実施の形態１とは異なり、算出結果を他の熱源機１ｂおよび１ｃに送信する必要はなく、自身の制御対象である熱源機１ａを制御するだけで目的を達成できる。さらに、各熱源機１ａ～１ｃに統合管理装置の機能を分散しているため、いずれかの熱源機が故障した場合も、空気調和装置１００Ａとして継続動作が可能である。また、本実施の形態における動作の説明では、各装置が自発的に熱源側制御装置５００に情報を送信する場合のフローを示したが、熱源側制御装置５００が必要に応じて各装置に情報を要求してもよい。 As described above, in the present embodiment, the heat source side information and the usage side information necessary for the calculation are transmitted from all the usage side control devices 60 and the heat source side control devices 500 to the respective heat source units 1a to 1c. Therefore, the calculation results of the control ability for the heat source devices 1a to 1c are the same. Therefore, unlike Embodiment 1, it is not necessary to transmit the calculation result to the other heat source devices 1b and 1c, and the object can be achieved only by controlling the heat source device 1a that is the control target. Furthermore, since the function of the integrated management device is distributed to each of the heat source units 1a to 1c, even if any one of the heat source units breaks down, the air conditioner 100A can be continuously operated. Further, in the description of the operation in the present embodiment, the flow in the case where each device spontaneously transmits information to the heat source side control device 500 is shown, but the heat source side control device 500 transmits information to each device as necessary. May be requested.
　また、本実施の形態の空気調和装置１００Ａにおいては、熱源機１ａ～１ｃの熱源側制御装置５００において、複数の利用側ユニット３ａ～３ｆの動作状態に応じて、自動的に熱源機１ａ～１ｃの運転制御を行う構成となっている。また、複数の熱源機１ａ～１ｃおよび利用側ユニット３ａ～３ｆは、それぞれ同一の一対の２次側熱媒体配管５に並列に接続される。これにより、上記実施の形態１と同様の効果を得ることができる。さらに、本実施の形態では統合管理装置８を備える必要がないため、部品点数および製品コストの削減が可能となる。 Further, in the air conditioner 100A of the present embodiment, the heat source devices 1a to 1c are automatically selected in the heat source side control device 500 of the heat source devices 1a to 1c according to the operating states of the plurality of usage side units 3a to 3f. The operation control is performed. The plurality of heat source devices 1a to 1c and the use side units 3a to 3f are connected in parallel to the same pair of secondary heat medium pipes 5, respectively. Thereby, the same effect as the first embodiment can be obtained. Furthermore, since it is not necessary to provide the integrated management device 8 in the present embodiment, the number of parts and the product cost can be reduced.
　実施の形態３．
　続いて、本発明の実施の形態３について説明する。実施の形態２の空気調和装置１００Ａにおいて、例えば、熱源機１ａが通信異常等により、一時的に他の熱源機１ｂおよび１ｃの熱源側情報ならびに利用側ユニット３ａ～３ｆの利用側情報を受信できないことがある。その場合、他の熱源機１ｂおよび１ｃと、算出した制御用運転能力が異なることで、空気調和装置１００として期待された制御が行われない可能性がある。そこで、実施の形態３では、複数の熱源機１ａ～１ｃの間で状態を共有する構成を備える点において実施の形態２と相違する。その他の空気調和装置１００Ａの構成については、実施の形態２と同様である。 Embodiment 3 FIG.
Subsequently, Embodiment 3 of the present invention will be described. In the air conditioner 100A of the second embodiment, for example, the heat source unit 1a cannot temporarily receive the heat source side information of the other heat source units 1b and 1c and the usage side information of the usage side units 3a to 3f due to a communication abnormality or the like. Sometimes. In this case, the control expected for the air conditioner 100 may not be performed because the calculated control driving ability is different from those of the other heat source devices 1b and 1c. Therefore, the third embodiment is different from the second embodiment in that a configuration is provided in which a state is shared among the plurality of heat source units 1a to 1c. Other configurations of the air conditioner 100A are the same as those in the second embodiment.
　本実施の形態における制御構成は、図９に示す実施の形態２と同様である。また、リモートコントローラー７ａ～７ｆおよび利用側ユニット３ａ～３ｆの動作も実施の形態２と同様である。 The control configuration in the present embodiment is the same as that in the second embodiment shown in FIG. The operations of the remote controllers 7a to 7f and the use side units 3a to 3f are the same as those in the second embodiment.
［熱源機１ａ～１ｃ］
　図１１は、本実施の形態における熱源機１ａの動作を示すフローチャートである。その他の熱源機１ｂおよび１ｃは、熱源機１ａと同様の動作を行う。本実施の形態では、情報取得部５０７によって、熱源機１ａの熱源側情報に変更があったか否かが判断される（Ｓ５０）。熱源機１ａの熱源側情報に変更がない場合は（Ｓ５０：ＮＯ）、変更があるまで待機する。一方、熱源機１ａの熱源側情報に変更があった場合は（Ｓ５０：ＹＥＳ）、変更後の熱源側情報が取得され、通信部５０１を介して送信され（Ｓ５１）、ステップＳ５０に戻る。 [Heat source machines 1a to 1c]
FIG. 11 is a flowchart showing the operation of the heat source unit 1a in the present embodiment. The other heat source units 1b and 1c perform the same operation as the heat source unit 1a. In the present embodiment, the information acquisition unit 507 determines whether or not the heat source side information of the heat source device 1a has been changed (S50). When there is no change in the heat source side information of the heat source device 1a (S50: NO), the process waits until there is a change. On the other hand, when there is a change in the heat source side information of the heat source unit 1a (S50: YES), the changed heat source side information is acquired and transmitted via the communication unit 501 (S51), and the process returns to step S50.
　また、上記の処理と並行して、図１０に示す実施の形態２と同様に、ステップＳ４１からステップＳ４６が実施される。そして、ステップＳ４６にて制御情報が生成されると、状態共有処理が実行される（Ｓ５２）。図１２は、状態共有処理の流れを示すフローチャートである。本処理では、ステップＳ４６で生成された制御情報が、熱源側情報と同様に他の熱源機１ｂおよび１ｃが受信できる方式で通信部５０１から送信される（Ｓ５３）。そして、通信部５０１にて、他の熱源機１ｂまたは１ｃから制御情報を受信したか否かが判断される（Ｓ５４）。そして、他の熱源機１ｂまたは１ｃから制御情報を受信した場合（Ｓ５４：ＹＥＳ）、制御情報生成部５０５によって、自身で生成した制御情報と受信した制御情報とが一致するか否かが判断される（Ｓ５５）。そして、受信した制御情報と、自身で生成した制御情報とが一致する場合は（Ｓ５５：ＹＥＳ）、ステップＳ６１に進む。 In parallel with the above processing, steps S41 to S46 are performed as in the second embodiment shown in FIG. And if control information is produced | generated in step S46, a state sharing process will be performed (S52). FIG. 12 is a flowchart showing the flow of the state sharing process. In this process, the control information generated in step S46 is transmitted from the communication unit 501 in a manner that can be received by the other heat source devices 1b and 1c, similarly to the heat source side information (S53). And it is judged in the communication part 501 whether the control information was received from the other heat-source equipment 1b or 1c (S54). And when control information is received from other heat-source equipment 1b or 1c (S54: YES), it is judged by the control information generation part 505 whether the control information produced | generated and the received control information correspond. (S55). If the received control information matches the control information generated by itself (S55: YES), the process proceeds to step S61.
　一方、受信した制御情報と自身で生成した制御情報とが一致しない場合（Ｓ５５：ＮＯ）、通信部５０１を介して送信元である熱源機１ｂまたは１ｃに対し、制御情報の生成に使用した各機器の熱源側情報および利用側情報が要求される（Ｓ５６）。そして、更新部５０３によって、他の熱源機１ｂまたは１ｃから受信した熱源側情報および利用側情報と、記憶部５０２に記憶される熱源側情報および利用側情報とが比較され、記憶部５０２に記憶される熱源側情報および利用側情報が最新であるか否かが判断される（Ｓ５７）。 On the other hand, when the received control information and the control information generated by itself do not match (S55: NO), each of the heat source machines 1b or 1c that is a transmission source via the communication unit 501 is used to generate control information. The heat source side information and the use side information of the device are requested (S56). Then, the update unit 503 compares the heat source side information and the use side information received from the other heat source device 1 b or 1 c with the heat source side information and the use side information stored in the storage unit 502 and stores them in the storage unit 502. It is determined whether the heat source side information and the use side information to be updated are the latest (S57).
　ここで、本実施の形態においては、熱源機１ａ～１ｃおよび利用側ユニット３ａ～３ｆが、熱源側情報および利用側情報を送信する際、機器毎に連番の識別番号が一緒に送信される。そして、更新部５０３は、記憶部５０２に記憶される熱源側情報および利用側情報の識別番号と、他の熱源機１ｂまたは１ｃから受信した熱源側情報および利用側情報の識別番号とを比較し、記憶部５０２に記憶される熱源側情報および利用側情報の識別番号が受信した熱源側情報および利用側情報の識別番号よりも新しい場合、記憶部５０２に記憶される熱源側情報および利用側情報が最新であると判断する。そして、記憶部５０２に記憶される熱源側情報および利用側情報が最新である場合（Ｓ５７：ＹＥＳ）、ステップＳ６１に進む。 Here, in the present embodiment, when the heat source devices 1a to 1c and the use side units 3a to 3f transmit the heat source side information and the use side information, serial number identification numbers are transmitted together for each device. . Then, the updating unit 503 compares the identification number of the heat source side information and the usage side information stored in the storage unit 502 with the identification number of the heat source side information and the usage side information received from the other heat source unit 1b or 1c. When the identification number of the heat source side information and the usage side information stored in the storage unit 502 is newer than the received identification number of the heat source side information and the usage side information, the heat source side information and the usage side information stored in the storage unit 502 Is determined to be up-to-date. And when the heat-source side information and utilization side information which are memorize | stored in the memory | storage part 502 are the newest (S57: YES), it progresses to step S61.
　一方、記憶部５０２に記憶される熱源側情報および利用側情報が最新でない場合（Ｓ５７：ＮＯ）、通信異常等により、一時的に他の熱源機１ｂまたは１ｃ、もしくは利用側ユニット３ａ～３ｆからの熱源側情報および利用側情報を受信できなかったと判断される。そして、更新部５０３によって、記憶部５０２に記憶される熱源側情報および利用側情報が、他の熱源機１ｂまたは１ｃから受信した熱源側情報および利用側情報に更新される（Ｓ５８）。そして、ステップＳ４５およびＳ４６と同様に、更新された熱源側情報および利用側情報に基づいて、合計運転能力が算出され（Ｓ５９）、算出された合計運転能力から制御情報が生成される（Ｓ６０）。ステップＳ５９およびＳ６０で算出および生成された合計運転能力および制御情報によって、ステップＳ４５およびＳ４６で算出および生成された合計運転能力および制御情報が更新される。 On the other hand, when the heat source side information and the use side information stored in the storage unit 502 are not the latest (S57: NO), due to a communication abnormality or the like, temporarily from another heat source machine 1b or 1c or the use side units 3a to 3f. It is determined that the heat source side information and the use side information of the user could not be received. Then, the update unit 503 updates the heat source side information and the use side information stored in the storage unit 502 to the heat source side information and the use side information received from the other heat source machine 1b or 1c (S58). Then, similarly to steps S45 and S46, the total operating capacity is calculated based on the updated heat source side information and usage side information (S59), and control information is generated from the calculated total operating capacity (S60). . The total driving ability and control information calculated and generated in steps S45 and S46 are updated with the total driving ability and control information calculated and generated in steps S59 and S60.
　そして、ステップＳ６１では、熱源機１ａに接続される全ての熱源機１ｂおよび１ｃから制御情報を受信したか否かが判断される（Ｓ６１）。そして、全ての熱源機１ｂおよび１ｃから制御情報を受信していない場合は、ステップＳ５４に戻る。そして、以降のステップを繰り返し、全ての熱源機１ｂおよび１ｃの制御情報との比較および状態の共有化を行う。そして、全ての熱源機１ｂおよび１ｃから制御情報を受信した場合（Ｓ６１：ＹＥＳ）、本処理を終了し、図１１のステップＳ４７に進む。 In step S61, it is determined whether control information has been received from all the heat source devices 1b and 1c connected to the heat source device 1a (S61). And when control information is not received from all the heat source machines 1b and 1c, it returns to step S54. Then, the subsequent steps are repeated to compare with the control information of all the heat source devices 1b and 1c and share the state. And when control information is received from all the heat source machines 1b and 1c (S61: YES), this process is complete | finished and it progresses to step S47 of FIG.
　一方、ステップＳ５４にて制御情報を受信していない場合は（Ｓ５４：ＮＯ）、所定の時間が経過したか否かが判断され（Ｓ６２）、所定の時間が経過するまで（Ｓ６２：ＮＯ）、制御情報の受信を待機する。なお、このとき、熱源機１ａが制御情報の受信に失敗した可能性があるため、制御情報を受信していない熱源機１ｂまたは１ｃに対して制御情報の送信を要求してもよい。そして、所定の時間が経過した場合（Ｓ６２：ＹＥＳ）は、本処理を終了し、図１１のステップＳ４７に進む。この場合は、制御情報が受信されなかった熱源機が故障している可能性があるため、制御情報が受信されなかった熱源機を除く熱源機の制御情報を対象に比較と共有化が行われる（Ｓ５５～Ｓ６０）。なお、別の実施の形態では、図１１のステップＳ４７に進む替りに、通信異常を通知する警告を行い、処理を中断してもよい。 On the other hand, if control information has not been received in step S54 (S54: NO), it is determined whether or not a predetermined time has elapsed (S62), and until a predetermined time has elapsed (S62: NO), Wait for reception of control information. At this time, since the heat source unit 1a may have failed to receive the control information, the heat source unit 1b or 1c that has not received the control information may be requested to transmit the control information. If the predetermined time has elapsed (S62: YES), this process is terminated, and the process proceeds to step S47 in FIG. In this case, there is a possibility that the heat source unit that has not received the control information may be out of order. Therefore, the control information of the heat source units other than the heat source unit that has not received the control information is compared and shared. (S55 to S60). In another embodiment, instead of proceeding to step S47 in FIG. 11, a warning for notifying a communication abnormality may be given and the process interrupted.
　そして、図１１に戻って、ステップＳ４７では、ステップＳ４６にて生成された制御情報またはステップＳ６０で生成（更新）された制御情報に基づいて、熱源機１ａの各部が制御される（Ｓ４７）。 Returning to FIG. 11, in step S47, each part of the heat source unit 1a is controlled based on the control information generated in step S46 or the control information generated (updated) in step S60 (S47).
　なお、ステップＳ５７にて、記憶部５０２に記憶される熱源側情報および利用側情報が最新であると判断された場合（Ｓ５７：ＹＥＳ）、またはステップＳ６２にて、制御情報が受信されないまま所定の時間が経過した場合（Ｓ６２：ＹＥＳ）、熱源側情報および利用側情報の送信元である熱源機１ｂまたは１ｃに通信異常が発生し、利用側情報の受信に失敗した可能性があると判断し、熱源機１ｂまたは１ｃに自身（熱源機１ａ）の熱源側情報および利用側情報を送信し、制御情報の再生成を行わせてもよい。 In step S57, when it is determined that the heat source side information and the use side information stored in the storage unit 502 are the latest (S57: YES), or in step S62, the control information is not received and the predetermined information is received. When the time has elapsed (S62: YES), it is determined that there is a possibility that communication error has occurred in the heat source machine 1b or 1c, which is the transmission source of the heat source side information and the usage side information, and reception of the usage side information may have failed. The heat source device 1b or 1c may transmit the heat source side information and the use side information of itself (the heat source device 1a) to regenerate the control information.
　以上のように、本実施の形態においては、通信異常等により、一時的に他の熱源機１ｂおよび１ｃならびに利用側ユニット３ａ～３ｆからの熱源側情報および利用側情報を受信することができなかった場合にも、複数の熱源機１ａ～１ｃで同じ制御情報（制御用運転能力）を生成することができ、空気調和装置１００Ａとして期待された制御を行うことができる。また、空気調和装置１００Ａの対故障性の向上も図ることができる。 As described above, in the present embodiment, the heat source side information and the use side information from the other heat source units 1b and 1c and the use side units 3a to 3f cannot be temporarily received due to a communication abnormality or the like. In this case, the same control information (control operation capability) can be generated by the plurality of heat source devices 1a to 1c, and the control expected as the air conditioner 100A can be performed. Further, the fault tolerance of the air conditioner 100A can be improved.
　以上、本発明の実施の形態について図面に基づいて説明したが、具体的な構成は、これに限られるものでなく、発明の要旨を逸脱しない範囲で変更可能である。例えば、熱源側制御装置５０、利用側制御装置６０および統合管理装置８は、伝送線６を介して接続される構成としたが、これに限定されるものではなく、無線通信を行う構成としてもよい。また、上記実施の形態１の説明では、熱源機１ａ～１ｃが空冷式のヒートポンプチラーの場合を説明したが、熱源機１ａ～１ｃの構成はこれに限定されない。例えば、熱源機１ａ～１ｃが水冷式のヒートポンプチラーまたは吸収式冷凍機などの場合にも本発明を適用することが可能である。また、利用側ユニット３ａ～３ｆにおいて、２管式だけでなく４管式の場合でも本発明の適用が可能である。 The embodiment of the present invention has been described above with reference to the drawings. However, the specific configuration is not limited to this, and can be changed without departing from the gist of the invention. For example, the heat source side control device 50, the use side control device 60, and the integrated management device 8 are configured to be connected via the transmission line 6, but are not limited thereto, and may be configured to perform wireless communication. Good. In the description of the first embodiment, the case where the heat source units 1a to 1c are air-cooled heat pump chillers has been described. However, the configuration of the heat source units 1a to 1c is not limited to this. For example, the present invention can also be applied when the heat source devices 1a to 1c are water-cooled heat pump chillers or absorption refrigerators. In addition, in the use side units 3a to 3f, the present invention can be applied to not only the 2-tube type but also the 4-pipe type.
　また、上記実施の形態３は、熱源機１ａ～１ｃが送信対象の動作状態が変化した場合に熱源側情報および利用側情報を送信する場合の例であるが、これに限定されるものではない。例えば、実施の形態１および実施の形態２のように、熱源機１ａ～１ｃおよび利用側ユニット３ａ～３ｆが定期的に熱源側情報を送信する構成の場合、期間内に熱源側情報を受信できなかった場合に、通信異常が発生したと判断してもよい。この場合は、熱源側情報および利用側情報を受信できなかった熱源機１ａ～１ｃまたは利用側ユニット３ａ～３ｆの何れかに問い合わせを行い、問い合わせに対する応答がなかった場合は該当機器の故障と判断される。一方、応答があった場合は熱源側情報および利用側情報の要求を行い、最新の熱源側情報および利用側情報に基づいて制御情報が生成される。 The third embodiment is an example in which the heat source devices 1a to 1c transmit the heat source side information and the usage side information when the operation state of the transmission target changes, but the present invention is not limited to this. . For example, in the case where the heat source devices 1a to 1c and the use side units 3a to 3f regularly transmit the heat source side information as in the first embodiment and the second embodiment, the heat source side information can be received within the period. If not, it may be determined that a communication error has occurred. In this case, an inquiry is made to any of the heat source devices 1a to 1c or the use side units 3a to 3f that have failed to receive the heat source side information and the use side information, and if there is no response to the inquiry, it is determined that the corresponding device has failed. Is done. On the other hand, when there is a response, a request for heat source side information and user side information is made, and control information is generated based on the latest heat source side information and user side information.
　さらに、上記実施の形態３の状態共有処理において、ステップＳ５３で他の熱源機１ｂおよび１ｃに制御情報を送信する構成としたが、ステップＳ４５で算出された合計運転能力を送信する構成としてもよい。この場合は、ステップＳ５５で、他の熱源機１ｂまたは１ｃの合計運転能力と比較を行い、状態の共有化が行われる。 Furthermore, in the state sharing process of the third embodiment, the control information is transmitted to the other heat source devices 1b and 1c in step S53.
