次に動作について説明する。  Next, the operation will be described.
室外機 14ならびに室内機 2a, 2bには商用電源が電力量計 3を経由し電源線 4を 通じて給電されている。そこで、電力量計 3は室外機 1ならびに室内機 2a, 2bの全て に供給される合計電力量を計測し、合計電力量に係るパルス信号を室外機 14へ発 信する。室外機 14の電力量計接続回路 10 (全室内機用信号受信手段の例）は電力 量計 3からのパルス信号を受信し制御部 15へ送信する。制御部 15の中央制御装置 16 (全室内機電力量積算手段の例）は、電力量計接続回路 10から送信されたノ ル ス信号に基づいて室外機 14ならびに室内機 2a, 2b全ての合計電力量を積算しメモ リ 19に格納する。また、中央制御装置 16 (室内機運転情報収集手段の例）は、伝送 線 7および通信回路部 17を通じて室内機 2a, 2bの運転情報を個別に収集しメモリ 1 9に格納する。そこで、中央制御装置 16 (電力量按分手段の例）は、いずれもメモリ 1 9に記憶されている室内機 2a, 2b個別の運転情報をもとに、積算された室外機 14な らびに室内機 2a, 2b全ての合計電力量を各室内機 2a, 2bごとの積算電力量に按分 する。  Commercial power is supplied to the outdoor unit 14 and the indoor units 2a and 2b through the watt-hour meter 3 through the power line 4. Therefore, the watt-hour meter 3 measures the total power supplied to all of the outdoor unit 1 and the indoor units 2a and 2b, and transmits a pulse signal related to the total power to the outdoor unit 14. The watt-hour meter connection circuit 10 of the outdoor unit 14 (an example of signal reception means for all indoor units) receives the pulse signal from the watt-hour meter 3 and transmits it to the control unit 15. The central controller 16 of the control unit 15 (an example of total indoor unit energy accumulation means) is based on the noise signal transmitted from the watt-hour meter connection circuit 10 and the total power of all of the outdoor units 14 and the indoor units 2a and 2b. Accumulate the amount and store in memory 19. The central controller 16 (an example of indoor unit operation information collecting means) individually collects the operation information of the indoor units 2a and 2b through the transmission line 7 and the communication circuit unit 17 and stores them in the memory 19. Therefore, the central controller 16 (an example of the electric energy apportioning means) is based on the individual operation information stored in the memory 19 for each of the indoor units 2a and 2b. The total electric energy of all units 2a and 2b is apportioned to the integrated electric energy for each indoor unit 2a and 2b.
例えば、室内機 2aの単位時間当たりの消費電力が 2. 8kW、室内機 2bの単位時間 当たりの消費電力が 5. 6kWで同時運転がなされ、その時間に電力量計 3から取り込 んだ消費電力が 3kWであったとする。この場合、 3kWは、室内機 2a, 2bの消費電力 比 1 : 2で比例按分して、室内機 2a、ならびに室内機 2a分の室外機 14の消費電力を lkWとし、室内機 2b、ならびに室内機 2b分の室外機 14の消費電力を 2kWとするよ うに按分される。 For example, the power consumption per unit time of indoor unit 2a is 2.8 kW, and the power consumption per unit time of indoor unit 2b is 5.6 kW. Assume that the power is 3kW. In this case, 3kW is proportionally proportional to the power consumption ratio 1: 2 of indoor units 2a and 2b, and the power consumption of outdoor unit 14 for indoor unit 2a and indoor unit 2a is lkW. The power consumption of the outdoor unit 14 for the unit 2b is 2kW. It is apportioned.
[0024] 以上のように、室外機 14ならびに室内機 2a, 2bは、電力量計 3を経由して配線さ れた電源線 4を使用して給電されているとともに伝送線 7を介して通信接続されてい るので、室外機 14が室内機 2a, 2bの運転情報を収集し、室内機 2a, 2bの機種ゃ収 集した運転情報などに応じて消費電力量を按分することができる。  [0024] As described above, the outdoor unit 14 and the indoor units 2a and 2b are fed using the power line 4 wired via the watt hour meter 3 and communicate via the transmission line 7. Since they are connected, the outdoor unit 14 can collect the operation information of the indoor units 2a and 2b, and can apportion the power consumption according to the operation information collected by the types of the indoor units 2a and 2b.
上記の説明は、室内機 2a, 2bの単位時間当たりの消費電力と ONZOFF状態の みを運転情報として電力量を按分する例について説明して 、る力 例えば冷媒の流 量を検出し、この検出流量を運転情報にして電力量を按分する t 、う態様であつても 、本実施の形態にて同様に対応できることは言うまでもない。  The above explanation describes an example in which the electric energy is apportioned using only the power consumption per unit time of the indoor units 2a and 2b and the ONZOFF state as the operation information. It goes without saying that the present embodiment can be similarly applied even if the power amount is apportioned using the flow rate as operating information.

The watt-hour meter 3 and the outdoor unit 14 are communicatively connected via a control wiring 5. The outdoor unit 14 and the indoor units 2a and 2b are connected to the centralized controller 6 through a transmission line 7 (transmission path). The centralized controller 6 (an example of the centralized control device) controls the operation of the outdoor unit 14 and the indoor units 2a and 2b, and displays the operation status of the outdoor unit 1 and the indoor units 2a and 2b on the display unit. . Furthermore, as described in the first embodiment, the outdoor unit 14 includes the refrigerant circuit unit 8, the inverter unit 9, the watt-hour meter connection circuit 10 connected via the watt-hour meter 3 and the control wiring 5, and The refrigerant circuit unit 8, the inverter unit 9, and the control unit 15 connected to the watt-hour meter connection circuit 10 are configured. The control unit 15 exchanges control with the central control device 16 composed of a microcomputer, the communication circuit unit 17 for communication, the watt-hour connection unit 10, the inverter unit 9, and the refrigerant circuit unit 8. It comprises an input / output circuit 18 for performing control and a memory 19 for storing a control state and the like. Next, the operation will be described.
室外機 14ならびに室内機 2a, 2bには、商用電源が電力量計 3を経由し電源線 4を 通じて給電されている。そこで、電力量計 3で計測された電力量に係るパルス信号は 制御配線 5を経由して、室外機 14の電力量計接続回路 10にて取り込まれ、室外機 1 4の制御部 15の中央制御装置 16により電力量が積算される。さらに、中央制御装置 16 (単位電力量算出手段の例）は、積算した電力量およびタイマ計時力 単位時間 ごとの電力量を算出する。通信回路部 17 (送信手段の例）は、算出された単位時間 ごとの電力量を伝送線 7を介して集中コントローラ 6に送信する。集中コントローラ 6は 、受信した単位時間ごとの電力量をコントローラ表示部 (不図示）に表示する。  Commercial power is supplied to the outdoor unit 14 and the indoor units 2a and 2b through the watt-hour meter 3 through the power line 4. Therefore, the pulse signal related to the electric energy measured by the watt-hour meter 3 is captured by the watt-hour meter connection circuit 10 of the outdoor unit 14 via the control wiring 5 and is sent to the center of the control unit 15 of the outdoor unit 14. The amount of electric power is integrated by the control device 16. Further, the central control device 16 (an example of unit power amount calculation means) calculates the integrated power amount and the power amount per unit of the timer timing force unit time. The communication circuit unit 17 (an example of a transmission unit) transmits the calculated amount of power per unit time to the centralized controller 6 via the transmission line 7. The centralized controller 6 displays the received power amount per unit time on a controller display unit (not shown).
[0027] 以上のように、室外機 14の制御部 15は通信回路部 17および伝送線 7を介して集 中コントローラ 6と接続されているので、室外機 14が算出した単位時間当たりの電力 量を集中コントローラ 6に送信して表示させたり電力料金に換算したりすることができ る。  [0027] As described above, since the control unit 15 of the outdoor unit 14 is connected to the centralized controller 6 via the communication circuit unit 17 and the transmission line 7, the electric energy per unit time calculated by the outdoor unit 14 Can be sent to the centralized controller 6 for display or converted into electricity charges.

The circuit unit 8, the inverter unit 9, and the control unit 21 connected to the watt-hour meter connection circuit 10 are configured. The control unit 21 performs control with the central control device 22 composed of a microcomputer, the communication circuit unit 17 for performing communication, the watt-hour meter connection unit 10, the inverter unit 9, and the refrigerant circuit unit 8. Take The input / output circuit 18 is configured to include a memory 19 that stores a control state, and a clock circuit unit 23 that measures time.
[0029] 次に動作について説明する。 Next, the operation will be described.
たとえば、午後 1時力 午後 3時までの時間帯で単位時間あたりの消費電力を最大 6kW (単位時間ごとの消費電力の制限値の例）として運転したい場合、かかる設定内 容は集中コントローラ 6の操作ボタンなど（図に表示せず)から予め設定入力され、伝 送線 7を介して室外機 20に送信される。そこで、室外機 20の制御部 21は、集中コン トローラ 6から送信された設定内容を通信回路部 17を経由して中央制御装置 22に取 り込む。力かる設定内容 (午後 1時力 午後 3時までは 1時間あたりの消費電力が最 大 6kW)はメモリ 19 (制限値記憶手段の例）に記憶される。また、室外機 20の制御部 21は、電力量計 3が計測した室外機 20および室内機 2a, 2bの消費電力量に係るパ ルス信号を電力量計接続回路 10を経由して受信している。そこで、制御部 21 (制御 手段の例）は、電力量計 3で計測された消費電力が近々制限値を上回りそうであると 判断した場合に、電力量計 3で計測された消費電力と、メモリ 19に保存されている消 費電力量の制限値 (6kW)と、時計回路部 23で計時されて 、る時刻とに基づ 、て、 インバータ部 9などを制御して消費電力を減らす。  For example, if you want to operate with a maximum power consumption per unit time of 6 kW (an example of the power consumption limit value per unit time) in the time zone from 1 pm to 3 pm, the settings are as follows: Settings are input in advance from operation buttons (not shown in the figure) and sent to the outdoor unit 20 via the transmission line 7. Therefore, the control unit 21 of the outdoor unit 20 takes in the setting content transmitted from the centralized controller 6 to the central control device 22 via the communication circuit unit 17. Powerful settings (power consumption at 1 pm, power consumption per hour up to 3 pm is 6 kW maximum) are stored in memory 19 (example of limit value storage means). The control unit 21 of the outdoor unit 20 receives a pulse signal related to the power consumption of the outdoor unit 20 and the indoor units 2a and 2b measured by the watt-hour meter 3 via the watt-hour connection circuit 10. Yes. Therefore, when the control unit 21 (an example of the control means) determines that the power consumption measured by the watt hour meter 3 is likely to exceed the limit value in the near future, the power consumption measured by the watt hour meter 3 Based on the power consumption limit value (6kW) stored in the memory 19 and the time measured by the clock circuit unit 23, the inverter unit 9 is controlled to reduce power consumption.
すなわち、上記の一例として、午後 1時から午後 3時までの時間帯は、 10分単位で消 費電力を lkW以下とするように、制御部 21は計測された消費電力量が lkWの 80% を上回った時点で、残りの時間はインバータ部 9の能力を 50%に抑えて運転すると V、つた制御を行 、、単位時間当たりの消費電力を抑えるのである。  In other words, as an example of the above, the control unit 21 has a measured power consumption of 80% of lkW so that the power consumption is less than lkW in units of 10 minutes during the time period from 1 pm to 3 pm When the time exceeds the value, the remaining time is V with the capacity of the inverter unit 9 kept at 50%, and the control is performed to reduce the power consumption per unit time.
[0030] 以上のように、室外機 20が、単位時間当たりの消費電力の制限値を記憶するととも に時計回路部 23による計時機能を有することで、単位時間当たりの消費電力量が制 限値を上回らないように室外機 20および室内機 2a, 2bを制御することができる。  [0030] As described above, the outdoor unit 20 stores the limit value of power consumption per unit time and has a clocking function by the clock circuit unit 23, so that the power consumption amount per unit time is the limit value. The outdoor unit 20 and the indoor units 2a and 2b can be controlled so as not to exceed.
[0031] 実施の形態 6.  [0031] Embodiment 6.
以上の実施の形態 1, 2, 3, 4, 5では、消費電力を計測、按分するとともに集中コ ントローラにて表示するもの、あるいは消費電力をもとに空気調和装置を制御するも のであつたが、次には、停電時に電力量計測を行なう実施の形態 6を説明する。 図 9はこの発明の実施の形態 6に係る室外機の構成を示すブロック構成図である。 室外機 24は、実施の形態 1でそれぞれ述べた、冷媒回路部 8と、インバータ部 9と、 発信装置付きの電力量計 3と制御配線 5を介して接続された電力量計接続回路 25と 、冷媒回路部 8、インバータ部 9、および電力量計接続回路 10に通信接続された制 御部 21とから構成されている。前記の電力量計接続部 25は、電力量計 3から発信さ れた電力量に係るパルス信号を取り込む入力部 26と、入力されたパルス信号に係る 電力量値を記憶する記憶部 27と、記憶された電力量値を制御部 21に出力する出力 部 28と、電力量計接続回路 25を動作させるために商用電源力も動作用電源を供給 する ACZDC変換回路 29 (交流直流変換回路の例）、および停電時に動作用電源 を供給するための 2次電池 30 (自己保持用電池の例）を内蔵した電源部 31とから構 成されている。 In the above embodiments 1, 2, 3, 4, and 5, the power consumption is measured and apportioned and displayed on a centralized controller, or the air conditioner is controlled based on the power consumption. However, a sixth embodiment in which power consumption is measured at the time of a power failure will be described next. FIG. 9 is a block configuration diagram showing the configuration of the outdoor unit according to Embodiment 6 of the present invention. The outdoor unit 24 includes the refrigerant circuit unit 8, the inverter unit 9, the watt-hour meter 3 with a transmission device, and the watt-hour meter connection circuit 25 connected via the control wiring 5, as described in the first embodiment. The refrigerant circuit unit 8, the inverter unit 9, and the control unit 21 communicatively connected to the watt-hour meter connection circuit 10. The watt hour meter connection unit 25 includes an input unit 26 that captures a pulse signal related to the electric energy transmitted from the watt hour meter 3, a storage unit 27 that stores an electric energy value related to the input pulse signal, and An output unit 28 that outputs the stored energy value to the control unit 21 and an ACZDC conversion circuit 29 that supplies power for operation as well as commercial power to operate the watt-hour meter connection circuit 25 (example of AC to DC conversion circuit) , And a power supply unit 31 having a built-in secondary battery 30 (an example of a self-holding battery) for supplying operating power in the event of a power failure.
[0032] 次に動作について説明する。 Next, the operation will be described.
電力量計 3が計測した電力量はパルス信号として制御配線 5を経由し室外機 24の電 力量計接続回路 25に送られる。このとき、室外機 24が停電していない場合、電力量 計接続回路 25の電源部 31は ACZDC変換回路 29にて電力量計接続回路 25に動 作用電源を供給している。そして、電力量計接続回路 25は、入力部 26で電力量計 3 力ものパルス信号を取り込み、そのパルス信号を記憶部 27に送る。記憶部 27は、送 られたパルス信号を出力部 28を経由して制御部 21に送る。  The electric energy measured by the watt hour meter 3 is sent as a pulse signal to the watt hour meter connection circuit 25 of the outdoor unit 24 via the control wiring 5. At this time, when the outdoor unit 24 is not out of power, the power supply 31 of the watt-hour connection circuit 25 supplies the operation power to the watt-hour connection circuit 25 by the ACZDC conversion circuit 29. Then, the watt-hour meter connection circuit 25 takes in a pulse signal of three watt-hour meters at the input unit 26 and sends the pulse signal to the storage unit 27. The storage unit 27 sends the transmitted pulse signal to the control unit 21 via the output unit 28.
一方で、室外機 24に供給される電源の遮断を電源部 31 (電源遮断検知手段の例） が検知すると、電源部 31 (電源切換手段の例）は電力量計接続回路 25用の動作用 電源を ACZDC変換回路 29から 2次電池 30に切り換える。そこで、電力量計接続 回路 25は、入力部 26で電力量計 3からのパルス信号を取り込み、このパルス信号に 係る電力量値を記憶部 27で記憶させる。記憶部 27に記憶されて 、る電力量値は、 電源が復電したのちに出力部 28を経由して制御部 21に送られる。  On the other hand, when the power source 31 (example of power cutoff detection means) detects the cutoff of the power supplied to the outdoor unit 24, the power source 31 (example of power switching means) is used for operation for the watt-hour connection circuit 25. Switch the power supply from the ACZDC converter circuit 29 to the secondary battery 30. Therefore, the watt-hour meter connection circuit 25 takes in the pulse signal from the watt-hour meter 3 at the input unit 26 and causes the storage unit 27 to store the watt-hour value related to this pulse signal. The electric energy value stored in the storage unit 27 is sent to the control unit 21 via the output unit 28 after the power is restored.
[0033] 以上のように、室外機 24の電力量計接続回路 25に、記憶部 27と 2次電池 30を備 える電源部 31を有していることで、停電などにより室外機 24が電源遮断された場合 でも電力量計 3の計測データを取りこぼす恐れがなくなる。 [0033] As described above, the watt-hour meter connection circuit 25 of the outdoor unit 24 includes the power supply unit 31 including the storage unit 27 and the secondary battery 30, so that the outdoor unit 24 is powered by a power failure or the like. Even if it is shut off, there is no risk of losing the measurement data of the electricity meter 3.
