次に、本実施の形態１の動作を図５乃至図８に基づいて説明する。図５は設定器の動作を示すフローチャート、図６は試運転時の室外機−１、−２の動作を示すフローチャート、図７は試運転時の全ての室内機の動作を示すフローチャート、図８は空気調和システム上の各機器のシーケンスを示す図である。なお、室外機−１のＩＤを室外ＩＤ＝１とし、室外機−２のＩＤを室外ＩＤ＝２として説明する。 Next, the operation of the first embodiment will be described with reference to FIGS. FIG. 5 is a flowchart showing the operation of the setting device, FIG. 6 is a flowchart showing the operations of the outdoor units-1 and -2 during the trial operation, FIG. 7 is a flowchart showing the operations of all the indoor units during the trial operation, and FIG. It is a figure which shows the sequence of each apparatus on a harmony system. In the following description, it is assumed that the ID of the outdoor unit-1 is the outdoor ID = 1 and the ID of the outdoor unit-2 is the outdoor ID = 2.

まず、設定器８の操作表示部８ａにより各室内機３のＩＤを入力して試験開始の操作を行い（Ｓ１）、次いで、室外機−１の室外ＩＤ＝１を入力して試験開始の操作を行うと（Ｓ２）、設定器８の機器状態統合部８ｂは、室内機３のＩＤ毎に試運転開始指示を通信管理部８ｃを通じて通信網９上に配信し（図８（ａ）参照）、その後、室外ＩＤ＝１と共に試運転開始指示を通信網９上に配信する（図８（ｂ）参照）。そして、室外機−１の試運転開始から所定時間（例えば５分）経過したかどうかを判定し（Ｓ３）、その時間を経過していないと判断したときは、その判定動作を所定時間経過するまで繰り返し行う。 First, the operation display unit 8a of the setting device 8 inputs the ID of each indoor unit 3 to perform a test start operation (S1), and then inputs the outdoor ID = 1 of the outdoor unit-1 to start the test. (S2), the device state integration unit 8b of the setting device 8 distributes a test run start instruction to the communication network 9 through the communication management unit 8c for each ID of the indoor unit 3 (see FIG. 8A). Thereafter, the test run start instruction is distributed on the communication network 9 together with the outdoor ID = 1 (see FIG. 8B). Then, it is determined whether or not a predetermined time (for example, 5 minutes) has elapsed since the start of the trial operation of the outdoor unit-1 (S3), and when it is determined that the time has not elapsed, the determination operation is continued until the predetermined time elapses. Repeat.

その所定時間が経過すると、機器状態統合部８ｂは、室外ＩＤ＝１を含ませた試験終了指示を通信網９上に配信して室外機−１に受信させ（図８（ｅ）参照）、試験を終了する（Ｓ４）。その後、操作表示部８ａの操作による室外ＩＤ＝２の入力及び試験開始の指示を検知すると、室外機−２への試験開始と判断して（Ｓ５）、試運転開始指示を室外ＩＤ＝２と共に通信網９上に配信する（図８（ｇ）参照）。そして、図５には図示していないが、室外機−２の試運転開始から所定時間（例えば５分）経過したかどうかを判定し、その時間を経過していないと判断したときは、その判定動作を所定時間経過するまで繰り返し、その時間が経過したときに、試験終了指示を室外ＩＤ＝２と共に通信網９上に配信して室外機−２に受信させ（図８（ｊ）参照）、試験を終了する。 When the predetermined time elapses, the device state integration unit 8b distributes the test end instruction including the outdoor ID = 1 to the communication network 9 to be received by the outdoor unit-1 (see FIG. 8E). The test is terminated (S4). Thereafter, when an input of outdoor ID = 2 and an instruction to start a test are detected by operation of the operation display unit 8a, it is determined that the test to the outdoor unit-2 is started (S5), and a test operation start instruction is communicated together with the outdoor ID = 2. Distribution is made on the network 9 (see FIG. 8G). Then, although not shown in FIG. 5, it is determined whether a predetermined time (for example, 5 minutes) has elapsed since the start of the trial operation of the outdoor unit-2, and when it is determined that the time has not elapsed, the determination The operation is repeated until a predetermined time elapses, and when the time elapses, the test end instruction is distributed to the communication network 9 together with the outdoor ID = 2 and received by the outdoor unit-2 (see FIG. 8 (j)). End the test.

一方、各室外機−１、−２の室外機制御部６ｂは、通信管理部６ｃに試験開始指示が受信されると（Ｓ１１）、その指示を取り込んで自己のＩＤ（室外ＩＤ＝１）が含まれているかどうかを判別する（Ｓ１２）。試験開始指示に自己のＩＤがないと判断したときは、Ｓ１１→Ｓ１２の動作を繰り返して待機状態となり、試験開始指示に自己のＩＤがあると試運転を開始する（Ｓ１３）。この場合は、室外機−１への試験開始指示であるため、室外機−１の室外機制御部６ｂは、本機を駆動して試運転を開始すると共に、自己のＩＤ（室外ＩＤ＝１）を通信管理部６ｃを通じて通信網９上に配信し（Ｓ１４）、試験終了指示が受信されたかどうかを判別する（Ｓ１５）。その指示が受信されていないときは、ここで待機状態となり、受信されたときはその指示に自己のＩＤが含まれているかどうかを判別する（Ｓ１６）。自己のＩＤが含まれていないときはＳ１５に戻って待機状態となる。この時、本機の試運転により冷媒が冷媒配管４を介して３台の室内機３に流れて循環し冷媒温度が低下していく（図８（ｃ）参照）。この試運転状態のときに、設定器８から送信された試験終了指示が室外ＩＤ＝１と共に受信されると（Ｓ１５，Ｓ１６）、室外機−１の室外機制御部６ｂは、本機の試運転を停止して（Ｓ１７）、冷媒の循環を停止させて元の状態にし（図８（ｆ）参照）、待機状態となる。 On the other hand, when the test start instruction is received by the communication management unit 6c (S11), the outdoor unit control unit 6b of each of the outdoor units-1 and -2 takes in the instruction and has its own ID (outdoor ID = 1). It is determined whether it is included (S12). When it is determined that the test start instruction does not have its own ID, the operation of S11 → S12 is repeated to enter a standby state, and when the test start instruction has its own ID, a test run is started (S13). In this case, since it is a test start instruction to the outdoor unit-1, the outdoor unit control unit 6b of the outdoor unit-1 drives this unit to start a test operation and also has its own ID (outdoor ID = 1). Is distributed over the communication network 9 through the communication manager 6c (S14), and it is determined whether or not a test end instruction has been received (S15). When the instruction has not been received, the process enters a standby state. When the instruction has been received, it is determined whether or not the instruction includes its own ID (S16). When the self ID is not included, the process returns to S15 and enters a standby state. At this time, the refrigerant flows through the three indoor units 3 through the refrigerant pipe 4 and circulates through the trial operation of this unit, and the refrigerant temperature decreases (see FIG. 8C). When the test end instruction transmitted from the setting device 8 is received together with the outdoor ID = 1 in this trial operation state (S15, S16), the outdoor unit control unit 6b of the outdoor unit-1 performs the trial operation of the unit. It stops (S17), stops the circulation of the refrigerant and returns to the original state (see FIG. 8 (f)), and enters a standby state.

その後に、設定器８から試験開始指示が室外ＩＤ＝２と共に配信されると、室外機−２の室外機制御部６ｂは、室外機−１と同様に、そのＩＤから自己への試運転開始と判断して（Ｓ１１〜Ｓ１２）、本機を駆動して試運転を開始し（Ｓ１３）、冷媒を冷媒配管５を介して３台の室内機３に流し循環させる（図８（ｈ）参照）。そして、自己のＩＤ（室外ＩＤ＝２）を通信網９上に配信して全ての室内機３に受信させる。その後、設定器８から送信された試験終了指示が室外ＩＤ＝２と共に受信されると（Ｓ１５，１６）、本機の試運転を停止して（Ｓ１７）、冷媒の循環を停止させて元の状態にし（図８（ｋ）参照）、待機状態となる。 After that, when the test start instruction is distributed from the setting device 8 together with the outdoor ID = 2, the outdoor unit control unit 6b of the outdoor unit-2 starts the trial operation from the ID to itself as in the outdoor unit-1. After judging (S11 to S12), the apparatus is driven to start a trial operation (S13), and the refrigerant is circulated through the refrigerant pipe 5 to the three indoor units 3 (see FIG. 8 (h)). Then, its own ID (outdoor ID = 2) is distributed on the communication network 9 and is received by all the indoor units 3. Thereafter, when the test end instruction transmitted from the setting device 8 is received together with the outdoor ID = 2 (S15, 16), the test operation of the machine is stopped (S17), and the circulation of the refrigerant is stopped to return to the original state. (See FIG. 8 (k)), a standby state is entered.

一方、各室内機３の室内機制御部７ｂは、通信管理部７ｄに試験開始指示が受信されると（Ｓ２１）、その指示を取り込んで自己のＩＤが含まれているかどうかを判別する（Ｓ２２）。試験開始指示に自己のＩＤがないと判断したときは、Ｓ２１→Ｓ２２の動作を繰り返して待機状態となり、試験開始指示に自己のＩＤがあると試運転を開始する（Ｓ２３）。この場合、全室内機３への試験開始指示であるため、それぞれの室内機制御部７ｂは、通信管理部７ｄを通じて室外機−１、−２からのＩＤが受信されたかどうかを判定し（Ｓ２４）、室外ＩＤ＝１が受信されたときは、そのＩＤを取り込んで一旦、対応室外機記憶部７ｃに格納（仮記憶）する（Ｓ２５）。 On the other hand, when the test start instruction is received by the communication management unit 7d (S21), the indoor unit control unit 7b of each indoor unit 3 takes in the instruction and determines whether or not its own ID is included (S22). ). When it is determined that the test start instruction does not have its own ID, the operation of S21 → S22 is repeated to enter a standby state, and when the test start instruction has its own ID, a test run is started (S23). In this case, since it is a test start instruction to all the indoor units 3, each indoor unit control unit 7b determines whether or not the IDs from the outdoor units -1 and -2 are received through the communication management unit 7d (S24). When the outdoor ID = 1 is received, the ID is fetched and temporarily stored (temporarily stored) in the corresponding outdoor unit storage unit 7c (S25).

そして、各室内機３の室内機制御部７ｂは、それぞれ本機内の温度センサを通じて冷媒配管４を循環する入力冷媒の温度が冷えたかどうかを判定し（Ｓ２６）、冷媒温度が冷えたことを感知したときは（図８（ｄ）参照）、仮記憶したＩＤから室外機−１と関連すると判断してその室外機−１の室外ＩＤ＝１を保持して（Ｓ２７）、本機内に設定されている自己のＩＤと室外ＩＤ＝１とを通信網９上に配信し（Ｓ２８）、設定器８に受信させる。この設定器８へのＩＤ配信は、室外機−１に連結されている３台の室内機３で、室外機−１に近い方から順に行われる。また、残りの３台の室内機３は、待機状態となる。 And the indoor unit control part 7b of each indoor unit 3 determines whether the temperature of the input refrigerant | coolant which circulates through the refrigerant | coolant piping 4 through the temperature sensor in this machine was respectively cooled (S26), and senses that the refrigerant temperature cooled. When it is done (see FIG. 8D), it is determined that it is related to the outdoor unit-1 from the temporarily stored ID, and the outdoor ID-1 of the outdoor unit-1 is held (S27) and set in the unit. The self ID and the outdoor ID = 1 are distributed on the communication network 9 (S28), and the setting device 8 receives them. The ID distribution to the setting device 8 is performed in order from the side closer to the outdoor unit-1 by the three indoor units 3 connected to the outdoor unit-1. The remaining three indoor units 3 are in a standby state.

室外機−１に連結されている３台の室内機３の室内機制御部７ｂは、その後、自己のＩＤが含まれた試験終了指示が受信されるまで待機状態となる（Ｓ２９，Ｓ３０）。この待機中に、図７のフローチャートには図示していないが、設定器８によって設定されたグループＩＤ及びアドレスが受信されると、対応室外機記憶部７ｃに保持している室外ＩＤ＝１と関連付けてその記憶部７ｃに記憶する。そして、自己のＩＤが含まれた試験終了指示が受信されると（Ｓ２９，Ｓ３０）、試運転を終了し（Ｓ３１）、Ｓ２１に戻って待機状態となる。なお、冷媒の冷えを感知しなかった他の室内機３は、仮記憶した室外機−１のＩＤを５分後に消去するようになっている。 Thereafter, the indoor unit control units 7b of the three indoor units 3 connected to the outdoor unit 1 are in a standby state until a test end instruction including their own IDs is received (S29, S30). Although not shown in the flowchart of FIG. 7 during this standby, when the group ID and address set by the setting unit 8 are received, the outdoor ID held in the corresponding outdoor unit storage unit 7c = 1. The data are stored in the storage unit 7c in association with each other. When a test end instruction including its own ID is received (S29, S30), the trial run is ended (S31), and the process returns to S21 and enters a standby state. The other indoor units 3 that have not sensed the cooling of the refrigerant are configured to erase the temporarily stored ID of the outdoor unit 1 after 5 minutes.

また、冷媒配管５に連結されている３台の室内機３においては、室外機−２のＩＤ（室外ＩＤ＝２）受信後に、図８（ｉ）に示すように冷媒の冷えを感知すると（Ｓ２１〜Ｓ２６）、前記と同様に、仮記憶したＩＤから室外機−２と関連すると判断してその室外機−２の室外ＩＤ＝２を保持して（Ｓ２７）、本機内に設定されている自己のＩＤと室外ＩＤ＝２とを通信網９上に配信し（Ｓ２８）、設定器８に受信させる。この設定器８へのＩＤ配信は、室外機−２に連結されている３台の室内機３で、室外機−２に近い方から順に行われる。 Further, in the three indoor units 3 connected to the refrigerant pipe 5, when the cooling of the refrigerant is detected as shown in FIG. 8 (i) after receiving the ID of the outdoor unit-2 (outdoor ID = 2) ( S21 to S26), similarly to the above, it is determined that the outdoor unit-2 is related from the temporarily stored ID, and the outdoor unit ID = 2 of the outdoor unit-2 is held (S27) and set in the unit. The self ID and the outdoor ID = 2 are distributed on the communication network 9 (S28), and the setting device 8 receives them. The ID distribution to the setting device 8 is performed in order from the side closer to the outdoor unit-2 by the three indoor units 3 connected to the outdoor unit-2.

室外機−２に連結されている３台の室内機３の室内機制御部７ｂは、前記と同様に、自己のＩＤが含まれた試験終了指示が受信されるまで待機状態となる（Ｓ２９，Ｓ３０）。この待機中に、図７のフローチャートには図示していないが、設定器８によって設定されたグループＩＤ及びアドレスが受信されると、対応室外機記憶部７ｃに保持している室外ＩＤ＝２と関連付けてその記憶部７ｃに記憶する。そして、自己のＩＤが含まれた試験終了指示が受信されると（Ｓ２９，Ｓ３０）、試運転を終了し（Ｓ３１）、Ｓ２１に戻って待機状態となる。なお、室外機−１と連結されている３台の室内機３は、仮記憶した室外機−２のＩＤを５分後に消去するようになっている。 Similarly to the above, the indoor unit control units 7b of the three indoor units 3 connected to the outdoor unit-2 are in a standby state until a test end instruction including their own ID is received (S29, S30). Although not shown in the flowchart of FIG. 7 during this standby, when the group ID and address set by the setting device 8 are received, the outdoor ID held in the corresponding outdoor unit storage unit 7c is set to 2. The data are stored in the storage unit 7c in association with each other. When a test end instruction including its own ID is received (S29, S30), the trial run is ended (S31), and the process returns to S21 and enters a standby state. Note that the three indoor units 3 connected to the outdoor unit-1 delete the temporarily stored ID of the outdoor unit-2 after 5 minutes.

一方、設定器８の機器状態統合部８ｂは、図５には図示していないが、室外機−１に連結されている３台の室内機３から順に送信されたそれぞれの自己のＩＤと室外ＩＤ＝１とが受信されると、受信の順にアドレスを割り当て、そして、室外ＩＤ＝１から同一グループと判断してグループＩＤを割り当てて、そのグループＩＤと各アドレスをそれぞれ組として該当する室内機３に受信させる。この後に、室外機−２に連結されている３台の室内機３から順に送信されたそれぞれの自己のＩＤと室外ＩＤ＝１とが受信されたときは、前記と同様に、アドレスを割り当て、室外ＩＤ＝２から同一グループと判断してグループＩＤを割り当てて、そのグループＩＤと各アドレスをそれぞれ組として室外機２側の３台の室内機３に受信させる。 On the other hand, although not shown in FIG. 5, the device state integration unit 8b of the setting device 8 has its own ID and outdoor transmitted sequentially from the three indoor units 3 connected to the outdoor unit-1. When ID = 1 is received, addresses are assigned in the order of reception, and from outdoor ID = 1, the same group is determined and a group ID is assigned. 3 to receive. Thereafter, when the respective IDs and outdoor ID = 1 transmitted in order from the three indoor units 3 connected to the outdoor unit-2 are assigned, the addresses are assigned in the same manner as described above. The outdoor ID = 2 is determined to be the same group and a group ID is assigned, and the group ID and each address are received as a set by the three indoor units 3 on the outdoor unit 2 side.

以上のように本実施の形態１によれば、試運転時に、システム上の全ての室内機３を運転状態にし、各室外機−１、−２を所定間隔で順次に運転させ、室外機−１（室外機−２）は、試運転が開始されると、自己の室外ＩＤ＝１（室外ＩＤ＝２）を全ての室内機３に送信し、全ての室内機３は、その室外ＩＤ＝１（室外ＩＤ＝２）を取り込んで記憶し、室外機から送られたきた循環冷媒の温度が冷えたとき、自己のＩＤと共に室外機−１の室外ＩＤ＝１（室外ＩＤ＝２）を設定器８に送信し、設定器８は、室内機３から順に送信された室内機のＩＤ及び室外機−１の室外ＩＤ＝１（室外ＩＤ＝２）が受信されると、受信の順にアドレスを割り当て、そして、室外ＩＤ＝１から同一グループと判断してグループＩＤを割り当てて、グループＩＤと各ＩＤをそれぞれ該当する室内機３に送信するようにしたので、室外機−１（室外機−２）とこれに連結された複数の室内機３との対応関係が自動的にわかり、複数の室内機３に自動的にアドレスを割り当てることができ、作業者の作業負担を軽減できるという効果がある。 As described above, according to the first embodiment, during the trial operation, all the indoor units 3 on the system are put into an operating state, and each of the outdoor units-1 and -2 are sequentially operated at a predetermined interval, so that the outdoor unit-1 When the trial operation is started, the (outdoor unit-2) transmits its own outdoor ID = 1 (outdoor ID = 2) to all the indoor units 3, and all the indoor units 3 have their outdoor ID = 1 ( Outdoor ID = 2) is taken in and stored, and when the temperature of the circulating refrigerant sent from the outdoor unit cools, the outdoor unit ID = 1 (outdoor ID = 2) of the outdoor unit-1 is set together with its own ID. When the setting unit 8 receives the indoor unit ID and the outdoor unit-1 outdoor ID = 1 (outdoor ID = 2) sequentially transmitted from the indoor unit 3, the setting unit 8 assigns addresses in the order of reception. Then, from outdoor ID = 1, it is determined that the group is the same, and a group ID is assigned. Since each ID is transmitted to the corresponding indoor unit 3, the correspondence relationship between the outdoor unit-1 (outdoor unit-2) and the plurality of indoor units 3 connected thereto is automatically known. An address can be automatically assigned to the indoor unit 3, and the work burden on the worker can be reduced.

なお、前記の実施の形態１では、室外機と対応関係のある複数の室内機３に対しグループＩＤと個々のアドレスとを割り当てるようにしたが、設定器８の操作表示部８ａにグループ毎のアドレスを室内機３の配置に応じて表示し、その操作表示部８ａの操作に基づいてそのアドレスを変更できるようにしてもよい。このようにアドレスを変更できるようにした場合、作業者に多少の負担をかけるものの、室内機３の配列に応じて任意にアドレスを設定でき、運転時の冷暖房を効率よく行うことが可能になる。 In the first embodiment, the group IDs and individual addresses are assigned to the plurality of indoor units 3 having a corresponding relationship with the outdoor unit. However, each group is assigned to the operation display unit 8a of the setting unit 8. The address may be displayed according to the arrangement of the indoor units 3 and the address may be changed based on the operation of the operation display unit 8a. When the address can be changed in this way, although it puts some burden on the operator, the address can be arbitrarily set according to the arrangement of the indoor units 3, and it becomes possible to efficiently perform air conditioning during operation. .

また、冷えた冷媒を感知した順にアドレスを付与するようにしたが、グループ毎の各室内機３にアドレスを割り当てる際、各室内機３に予め設定された位置情報（２次元座標系における位置座標）に基づいて連番のアドレスを割り当てるようにしてもよい。例えば、各室内機３の位置座標からＸ軸方向に並んでいる室内機３を判別して、それぞれに通し番号のアドレスを割り当て、次の列のＸ軸方向の室内機３にアドレスを割り当てる。これにより、アドレスを把握しやすく、アドレスの変更も容易になる。 In addition, addresses are assigned in the order in which the cooled refrigerant is sensed. However, when assigning addresses to the indoor units 3 for each group, position information (position coordinates in the two-dimensional coordinate system) set in advance for each indoor unit 3 is assigned. ) May be assigned serial number addresses. For example, the indoor units 3 arranged in the X-axis direction are discriminated from the position coordinates of each indoor unit 3, and an address of a serial number is assigned to each, and an address is assigned to the indoor unit 3 in the X-axis direction of the next row. As a result, it is easy to grasp the address, and the address can be easily changed.

実施の形態２．
実施の形態１では、室外機と対応関係にある複数の室内機に、設定器がアドレスを割り当てるようにしたが、本実施の形態２は、複数の室外機と、各室外機にそれぞれ連結された複数の室内機と、試運転時に、複数の室内機を運転状態にし、かつ各室外機を所定間隔で順次に運転させる室内機のコントローラとからなり、室外機と対応関係にある室内機相互がアドレスを設定するようにしたものである。実施の形態２の空気調和システムは、設定器８を除いて図１と同じであり、設定器８を室内機３のコントローラ８として説明する、また、室外機−１、−２の室外制御装置６と室内機３の室内制御装置７のブロック構成が基本的に同じであるため、図３及び図４を用いて説明する。 Embodiment 2. FIG.
In the first embodiment, the setting device assigns addresses to a plurality of indoor units corresponding to the outdoor unit. However, the second embodiment is connected to each of the plurality of outdoor units and each outdoor unit. A plurality of indoor units and a controller of the indoor unit that puts the plurality of indoor units into an operating state at the time of a test operation and sequentially operates each outdoor unit at a predetermined interval. An address is set. The air conditioning system of the second embodiment is the same as that shown in FIG. 1 except for the setting device 8, and the setting device 8 will be described as the controller 8 of the indoor unit 3. Also, the outdoor control devices of the outdoor units -1 and -2 6 and the indoor controller 7 of the indoor unit 3 are basically the same in block configuration, and will be described with reference to FIGS.

室内機３の室内制御装置７は、試運転時に室外機−１、−２からのＩＤ（室外ＩＤ＝１、室外ＩＤ＝２）が受信されるとそのＩＤを一時的に対応室外機記憶部７ｃに格納し、循環冷媒の温度変化、例えば冷媒の温度が冷えたことを温度センサ（図示せず）を通じて感知すると、他の室内機３によりアドレスが使用されているかどうかを判別し、アドレスが使用されているときは、例えば、そのアドレスの最後尾に続くアドレスを自己のアドレスとし、同一の室外機−１（室外機−２）のＩＤをグループＩＤとして個々に設定するアドレス判別手段と、アドレス判別手段により判別されたアドレス及びグループＩＤと対応室外機記憶部７ｃに格納した室外機−１（室外機−２）のＩＤとをコントローラ８に送信する送信手段とを備えている。コントローラ８は、室内機３のアドレス及びグループＩＤと室外機−１（室外機−２）のＩＤとを関連付けて保持する保持手段を備えている。 When the indoor control device 7 of the indoor unit 3 receives IDs (outdoor ID = 1, outdoor ID = 2) from the outdoor units-1 and -2 during the trial operation, the ID is temporarily associated with the outdoor unit storage unit 7c. When the temperature of the circulating refrigerant is sensed through a temperature sensor (not shown), for example, it is determined whether the address is used by another indoor unit 3, and the address is used. For example, an address discriminating unit that individually sets the address following the end of the address as its own address and sets the ID of the same outdoor unit-1 (outdoor unit-2) as a group ID, Transmitting means for transmitting the address and group ID determined by the determining means and the ID of the outdoor unit-1 (outdoor unit-2) stored in the corresponding outdoor unit storage unit 7c to the controller 8 is provided. The controller 8 includes holding means that holds the address and group ID of the indoor unit 3 and the ID of the outdoor unit-1 (outdoor unit-2) in association with each other.

次に、実施の形態２の動作を説明するが、コントローラ８の動作は、図５に示すフローチャートと同じであるため割愛し、また、室外機−１、−２の動作は、図６に示すフローチャートと同じであるため割愛して、室内機３の動作を図９に示すフローチャートを参照して説明する。
図９は実施の形態２における室内機の動作を示すフローチャートである。なお、図中に示すステップ番号のうち図７のフローチャートに示すステップ番号と同じ箇所は、実施の形態１の室内機の動作と同じであるため、その箇所については動作説明を省略する。 Next, the operation of the second embodiment will be described. Since the operation of the controller 8 is the same as the flowchart shown in FIG. 5, it is omitted, and the operations of the outdoor units 1 and -2 are shown in FIG. 6. Since this is the same as the flowchart, the operation of the indoor unit 3 will be described with reference to the flowchart shown in FIG.
FIG. 9 is a flowchart showing the operation of the indoor unit in the second embodiment. In addition, since the same location as the step number shown to the flowchart of FIG. 7 among the step numbers shown in the figure is the same as the operation | movement of the indoor unit of Embodiment 1, description of operation | movement is abbreviate | omitted about the location.

各室内機３の室内機制御部７ｂは、コントローラ８からの試験開始指示に基づいて試運転に入ると（Ｓ２１〜Ｓ２３）、室外機−１（室外機−２）からの室外ＩＤ＝１（室外ＩＤ＝２）を一時的に対応室外機記憶部７ｃに格納し（Ｓ２４，Ｓ２５）、本機内の温度センサを通じて冷媒配管４を循環する入力冷媒の温度が冷えたかどうかを判定し（Ｓ２６）、冷媒温度が冷えたことを感知したときは、仮記憶したＩＤから室外機−１（室外機−２）と関連すると判断してその室外機−１（室外機−２）の室外ＩＤ＝１（室外ＩＤ＝２）を保持する（Ｓ２７）。その後は、他の室内機３によりアドレスが使用されているかどうかを判別し（Ｓ２７１）、アドレスが使用されていないときは、例えば予め設定された先頭番号を自己のアドレスとし（Ｓ２７２）、また、アドレスが使用されているときは、そのアドレスの最後尾に続くアドレスを自己のアドレスとし（Ｓ２７３）、室外機−１（−２）のＩＤをグループＩＤとする（Ｓ２７４）。 When the indoor unit control unit 7b of each indoor unit 3 enters a test operation based on the test start instruction from the controller 8 (S21 to S23), the outdoor ID from the outdoor unit-1 (outdoor unit-2) = 1 (outdoor ID = 2) is temporarily stored in the corresponding outdoor unit storage unit 7c (S24, S25), and it is determined whether the temperature of the input refrigerant circulating through the refrigerant pipe 4 through the temperature sensor in the unit has cooled (S26). When it is sensed that the refrigerant temperature has cooled, it is determined that it is related to the outdoor unit-1 (outdoor unit-2) from the temporarily stored ID, and the outdoor ID of the outdoor unit-1 (outdoor unit-2) = 1 ( The outdoor ID = 2) is held (S27). Thereafter, it is determined whether or not the address is used by another indoor unit 3 (S271). When the address is not used, for example, a preset head number is set as its own address (S272). When the address is used, the address following the end of the address is set as its own address (S273), and the ID of the outdoor unit-1 (-2) is set as the group ID (S274).

そして、自己のアドレスとグループＩＤとを対応室外機記憶部７ｃに格納した室外機−１（室外機−２）のＩＤと関連付けて保持する。その後は、設定した自己のアドレス及びグループＩＤと対応室外機記憶部７ｃに格納した室外機−１（室外機−２）のＩＤとをコントローラ８に送信する。この一連の動作は、冷媒の温度変化（冷えた冷媒）を感知した室内機３がそれぞれ行う。一方、コントローラ８は、各室内機３から送信されるアドレス及びグループＩＤと室外機−１（室外機−２）のＩＤとを関連付けて保持する。 Then, the self address and the group ID are stored in association with the ID of the outdoor unit-1 (outdoor unit-2) stored in the corresponding outdoor unit storage unit 7c. Thereafter, the set self address and group ID and the ID of the outdoor unit-1 (outdoor unit-2) stored in the corresponding outdoor unit storage unit 7c are transmitted to the controller 8. This series of operations is performed by each of the indoor units 3 that senses the temperature change of the refrigerant (cooled refrigerant). On the other hand, the controller 8 associates and holds the address and group ID transmitted from each indoor unit 3 and the ID of the outdoor unit-1 (outdoor unit-2).

以上のように実施の形態２によれば、各室内機３は、冷媒の温度が冷えたことを感知すると、他の室内機３によりアドレスが使用されているかどうかを判別し、アドレスが使用されているときは、そのアドレスの最後尾に続くアドレスを自己のアドレスとし、同一の室外機−１（室外機−２）のＩＤをグループＩＤとして個々に設定して、対応室外機記憶部７ｃに格納した室外機−１（室外機−２）のＩＤと共にコントローラ８に送信して保持させるようにしたので、室外機−１（室外機−２）とこれに連結された複数の室内機３との対応関係が自動的にわかり、複数の室内機３に自動的にアドレスを割り当てることができ、作業者の作業負担を軽減できるという効果がある。 As described above, according to the second embodiment, when each indoor unit 3 senses that the temperature of the refrigerant has cooled, it determines whether the address is used by another indoor unit 3, and the address is used. If this is the case, the address following the end of the address is set as its own address, and the ID of the same outdoor unit-1 (outdoor unit-2) is individually set as a group ID and stored in the corresponding outdoor unit storage unit 7c. Since it was transmitted to the controller 8 and held together with the ID of the stored outdoor unit-1 (outdoor unit-2), the outdoor unit-1 (outdoor unit-2) and a plurality of indoor units 3 connected thereto Can be automatically identified, addresses can be automatically assigned to the plurality of indoor units 3, and the burden on the operator can be reduced.

なお、前記の実施の形態２では、室内機３側で自己のアドレスとグループＩＤとを設定するようにしたが、コントローラ８の操作表示部８ａにグループ毎のアドレスを室内機３の配置に応じて表示し、その操作表示部８ａの操作に基づいてそのアドレスを変更できるようにしてもよい。このようにアドレスを変更できるようにした場合、作業者に多少の負担をかけるものの、室内機３の配列に応じて任意にアドレスを設定でき、運転時の冷暖房を効率よく行うことが可能になる。 In the second embodiment, the address and the group ID are set on the indoor unit 3 side. However, the address for each group is set in the operation display unit 8a of the controller 8 according to the arrangement of the indoor unit 3. And the address may be changed based on the operation of the operation display unit 8a. When the address can be changed in this way, although it puts some burden on the operator, the address can be arbitrarily set according to the arrangement of the indoor units 3, and it becomes possible to efficiently perform air conditioning during operation. .

また、冷えた冷媒を感知した順にアドレスを設定するようにしたが、各室内機３に予め設定された位置情報（２次元座標系における位置座標）に基づいて連番のアドレスを割り当てるようにしてもよい。例えば、各室内機３の位置座標からＸ軸方向に並んでいる室内機３を判別して、それぞれに通し番号のアドレスを割り当て、次の列のＸ軸方向の室内機３にアドレスを割り当てる。これにより、アドレスを把握しやすく、アドレスの変更も容易になる。 In addition, the addresses are set in the order in which the cooled refrigerant is detected. However, sequential addresses are assigned based on position information (position coordinates in the two-dimensional coordinate system) set in advance in each indoor unit 3. Also good. For example, the indoor units 3 arranged in the X-axis direction are discriminated from the position coordinates of each indoor unit 3, and an address of a serial number is assigned to each, and an address is assigned to the indoor unit 3 in the X-axis direction of the next row. As a result, it is easy to grasp the address, and the address can be easily changed.
