Thus the increase of the cost of the entire air conditioning system can be limited. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

本発明は、空気調和システムに係り、特に、複数台の空気調和機が通信線で接続されている空気調和システム全体のエネルギー使用量を抑制する手段に関する。   The present invention relates to an air conditioning system, and more particularly, to a means for suppressing energy consumption of the entire air conditioning system in which a plurality of air conditioners are connected by communication lines.

従来、エネルギー使用量を抑制する手段としては、エネルギー使用量を抑制する装置(例えばデマンド装置など)を別途設置し、その装置から各空気調和機に対してエネルギー使用量を抑制する指令を出力し、上限エネルギー使用量以下となるよう抑制している。   Conventionally, as a means for suppressing energy consumption, a device for suppressing energy consumption (for example, a demand device) is separately installed, and a command for suppressing energy consumption is output from the device to each air conditioner. , The upper limit energy consumption is suppressed to be below.

特定空間利用者を指定する特定空間利用者指定手段と、複数の空間全体のエネルギー使用量が複数の空間全体の目標エネルギー量を超過しそうになった場合に、特定空間利用者が利用している特定空間に対する空気調和機の空調能力を省エネルギー契約に従って制限する省エネルギー制御システムが提案されている(例えば、特許文献１参照)。   Specific space user designation means to specify a specific space user, and the specific space user uses when the energy usage amount of the entire space is likely to exceed the target energy amount of the entire space An energy saving control system that restricts the air conditioning capability of an air conditioner for a specific space in accordance with an energy saving contract has been proposed (see, for example, Patent Document 1).

一元化された集中計算センターが、コントローラにピークカット指令を送信し、各コントローラに接続された空気調和機を省電力化する電気機器のデマンド制御システムも提案されている(例えば、特許文献２参照)。   There has also been proposed a demand control system for electrical equipment in which a centralized calculation center transmits a peak cut command to a controller to save power in an air conditioner connected to each controller (for example, see Patent Document 2). .

空調監視盤が、外部からのデマンド要求に応じて空調機の消費電流を下げる必要が生じた際、例えば空調負荷の小さい室内機から順に空調能力を低下させる指令を送信する空気調和機が提案されている(例えば、特許文献３参照)。   When an air conditioning monitoring panel needs to reduce the current consumption of an air conditioner in response to an external demand, for example, an air conditioner that sends a command to reduce the air conditioning capacity in order from an indoor unit with a smaller air conditioning load is proposed. (For example, refer to Patent Document 3).

既設の空気調和機システムの操作部と同等の操作入力可能な同等操作部と、デマンド監視ユニットからのデマンド制御信号を受けるとともに、同等操作部への設定入力を受けて既設の空気調和システムを制御する負荷制御部とからなるデマンド監視システムも提案されている(例えば、特許文献４参照)。   Equivalent operation unit capable of operation input equivalent to the operation unit of the existing air conditioner system and a demand control signal from the demand monitoring unit, and control of the existing air conditioning system by receiving setting input to the equivalent operation unit A demand monitoring system including a load control unit is also proposed (see, for example, Patent Document 4).

設定温度と室温との温度差の変化割合が大きい空気調和機の停止優先を高くし、デマンド制御装置が空気調和機全体のエネルギー使用量を抑制する空気調和機の電力デマンド制御装置が提案されている(例えば、特許文献５参照)。   A power demand control device for an air conditioner has been proposed in which the stop priority of an air conditioner with a large change rate of the temperature difference between the set temperature and room temperature is made higher, and the demand control device suppresses the energy consumption of the entire air conditioner. (See, for example, Patent Document 5).

特開２００４−１１６９７２号公報 (第６〜９頁 図１〜図６)JP 2004-116972 A (Pages 6-9, FIGS. 1-6) 特開２００２−０１０５３２号公報 (第８頁 図３，図４)Japanese Patent Laid-Open No. 2002-010532 (page 8, FIGS. 3 and 4) 特開２００１−３１７７９１号公報 (第３〜４頁 図１)Japanese Patent Laying-Open No. 2001-317791 (pages 3-4) 特開２０００−１４６２５６号公報 (第３〜５頁 図１，図６)Japanese Patent Laid-Open No. 2000-146256 (Pages 3 to 5 FIGS. 1 and 6) 特開平０６−３０３７２２号公報 (第３〜４頁 図１，図２)Japanese Patent Laid-Open No. 06-303722 (pages 3 to 4 and FIGS. 1 and 2)

上記従来技術では、いずれも、エネルギー使用量を抑制するために空気調和機とは別にエネルギー使用量を抑制する新たな装置が必要となり、新たに室内に増設されるこれらいずれかの装置と各室外機との間にそのための専用配線も引き回さなければならないので、機器増設および専用配線引き回しの手間などがコストアップ要因となる。   In each of the above prior arts, in order to reduce the energy consumption, a new device for reducing the energy consumption is required in addition to the air conditioner. Since dedicated wiring for this purpose must be routed between the machines, the labor required for equipment expansion and dedicated wiring routing becomes a factor of cost increase.

また、集中計算センターなどで、一元管理すると、例えば空調負荷の小さい室内機から順に空調能力を低下させる指令を送信する方式では、空調機使用者が知らないところで設定内容が勝手に変更されたり、リモコンを操作しても設定温度を調節できないなど、例えばホテルの隣室間で、設備の不備を疑ったり空調の効き目に不公平感を持たれたりするような不具合があった。   In addition, when centralized management is performed at a centralized calculation center or the like, for example, in a method of sending a command to reduce the air conditioning capacity in order from an indoor unit with a small air conditioning load, the setting contents can be changed without permission by the air conditioner user, For example, the temperature setting cannot be adjusted by operating the remote control. For example, there were problems such as doubting inadequate facilities or feeling of unfairness in the effectiveness of air conditioning between adjacent rooms in a hotel.

本発明の課題は、エネルギー使用量を抑制するデマンド装置などを増設しないで、複数台の空気調和機全体のエネルギー使用量を空気調和機全体で使用可能な上限エネルギー使用量以下に抑制する空気調和システムを提供することである。   An object of the present invention is to provide an air conditioner that suppresses the energy use amount of a plurality of air conditioners to a level that is less than or equal to the upper limit energy use amount that can be used by the whole air conditioner without adding a demand device that suppresses the energy use amount. Is to provide a system.

本発明は、上記課題を解決するために、室外機制御装置を搭載した室外機と室内機制御装置を搭載した室内機とを冷媒配管で接続した空気調和機ユニットを複数含み、すべての室外機制御装置と室内機制御装置と通信線で接続した空気調和システムにおいて、それぞれの室外機制御装置が、空気調和機全体の上限エネルギー使用量を記憶する手段と、通信線から他の空気調和機の通信データを傍受する手段と、傍受した通信データに基づいて空気調和機全体のエネルギー使用量を把握する手段と、エネルギー使用量が上限エネルギー使用量以上となった場合に連続運転時間が長い空気調和機ユニットから順に所定時間停止させその後に運転を再開させる手段とを含む空気調和システムを提案する。   In order to solve the above problems, the present invention includes a plurality of air conditioner units in which an outdoor unit equipped with an outdoor unit control device and an indoor unit equipped with an indoor unit control device are connected by refrigerant piping, and all the outdoor units In the air conditioning system connected to the control device and the indoor unit control device via the communication line, each outdoor unit control device stores means for storing the upper limit energy usage of the entire air conditioner, and other air conditioners from the communication line. Means for intercepting communication data, means for grasping the energy consumption of the entire air conditioner based on the intercepted communication data, and air conditioning with long continuous operation time when the energy consumption exceeds the upper limit energy consumption An air conditioning system including means for stopping for a predetermined time in order from the machine unit and then restarting operation is proposed.

本発明は、また、室外機制御装置を搭載した室外機と室内機制御装置を搭載した室内機とを冷媒配管で接続した空気調和機ユニットを複数含み、すべての室外機制御装置と室内機制御装置と通信線で接続した空気調和システムにおいて、それぞれの室内機制御装置が、空気調和機全体の上限エネルギー使用量を記憶する手段と、通信線から他の空気調和機の通信データを傍受する手段と、傍受した通信データに基づいて空気調和機全体のエネルギー使用量を把握する手段と、エネルギー使用量が上限エネルギー使用量以上となった場合に連続運転時間が長い空気調和機から順に所定時間停止させその後に運転を再開させる手段とを含む空気調和システムを提案する。   The present invention also includes a plurality of air conditioner units in which an outdoor unit equipped with the outdoor unit control device and an indoor unit equipped with the indoor unit control device are connected by refrigerant piping, and all the outdoor unit control devices and the indoor unit control are included. In the air conditioning system connected to the apparatus via a communication line, each indoor unit control device stores means for storing the upper limit energy usage of the entire air conditioner, and means for intercepting communication data of other air conditioners from the communication line And a means of grasping the energy usage of the entire air conditioner based on the intercepted communication data, and when the energy usage exceeds the upper limit energy usage, stop for a predetermined time in order from the air conditioner with long continuous operation time And an air conditioning system including means for resuming operation thereafter.

本発明によれば、室外機は、他の空気調和機の通信を傍受し空気調和機の総エネルギー使用量を取得し、エネルギー使用量が上限エネルギー使用量となるタイミングを検知した場合に、連続運転時間の長い空気調和機から強制停止させるので、空調の効き目に不公平感を持たせず、エネルギー使用量を抑制できる。   According to the present invention, the outdoor unit intercepts communication of another air conditioner, acquires the total energy usage of the air conditioner, and continuously detects when the timing at which the energy usage reaches the upper limit energy usage is detected. Since the air conditioner with a long operation time is forcibly stopped, the amount of energy used can be suppressed without giving an unfair feeling to the effectiveness of air conditioning.

また、本発明によれば、室内機は、他の空気調和機の通信を傍受し空気調和機の総エネルギー使用量を取得し、エネルギー使用量が上限エネルギー使用量以上となるタイミングを検知した場合に、連続運転時間の長い空気調和機から強制停止させるので、空調の効き目に不公平感を持たせず、エネルギー使用量を抑制できる。   Moreover, according to the present invention, when the indoor unit intercepts communication of another air conditioner, acquires the total energy usage amount of the air conditioner, and detects a timing when the energy usage amount is equal to or higher than the upper limit energy usage amount Moreover, since the air conditioner having a long continuous operation time is forcibly stopped, the amount of energy used can be suppressed without giving an unfair feeling to the effectiveness of air conditioning.

次に、図１〜図６を参照して、本発明による空気調和システムの実施例を説明する。   Next, with reference to FIGS. 1-6, the Example of the air conditioning system by this invention is described.

本実施例の空気調和機０(ａ，ｂ，ｃ)は、冷媒配管７(ａ，ｂ，ｃ)で接続されている室外機１(ａ，ｂ，ｃ)と室内機３(ａ，ｂ，ｃ)とからなる。   The air conditioner 0 (a, b, c) of the present embodiment includes an outdoor unit 1 (a, b, c) and an indoor unit 3 (a, b) connected by a refrigerant pipe 7 (a, b, c). , C).

室外機１(ａ，ｂ，ｃ)には、室外機制御装置２(ａ，ｂ，ｃ)が搭載され、室内機３(ａ，ｂ，ｃ)には、室内機制御装置４(ａ，ｂ，ｃ)が搭載され、通信線６xで接続されている。   The outdoor unit 1 (a, b, c) is equipped with an outdoor unit control device 2 (a, b, c), and the indoor unit 3 (a, b, c) has an indoor unit control unit 4 (a, b, c). b, c) are mounted and connected by a communication line 6x.

室外機１(ａ，ｂ，ｃ)および室内機３(ａ，ｂ，ｃ)は、主電源スイッチ１１から、電源線１２yと各空気調和機専用の電源スイッチ１０(ａ，ｂ，ｃ)とを介し、電源線１２x(ａ，ｂ，ｃ)により給電される。   The outdoor unit 1 (a, b, c) and the indoor unit 3 (a, b, c) are connected from the main power switch 11 to a power line 12y and a power switch 10 (a, b, c) dedicated to each air conditioner. The power is supplied by the power line 12x (a, b, c).

上限エネルギー使用量を室外機制御装置２(ａ，ｂ，ｃ)に設定する場合のみ、通信線６yにより、書込み装置８を室外機制御装置２(ａ，ｂ，ｃ)に接続する。書込み装置８は、通信インターフェースを備えた一般的なコンピュータである。   The writing device 8 is connected to the outdoor unit control device 2 (a, b, c) through the communication line 6y only when the upper limit energy usage is set in the outdoor unit control unit 2 (a, b, c). The writing device 8 is a general computer provided with a communication interface.

図２は、室外機制御装置２(ａ，ｂ，ｃ)の内部構成の一例を示すブロック図である。   FIG. 2 is a block diagram showing an example of the internal configuration of the outdoor unit control device 2 (a, b, c).

室外機制御装置２(ａ，ｂ，ｃ)は、ＲＯＭ，ＲＡＭ，Ａ／Ｄ変換器，入出力ポートなどの各種周辺回路を内蔵しているマイコン２０と、各種データを保存する記録媒体であるＥＥＰＲＯＭ２１と、室内機制御装置４(ａ，ｂ，ｃ)，他室外機制御装置２(ａ，ｂ，ｃ)，データ書込み装置８と通信する通信回路２２と、各種入力，各種出力を処理する入出力回路２４とからなり、これらの回路は、互いにシステムデバイス２５で接続されている。   The outdoor unit control device 2 (a, b, c) is a microcomputer 20 incorporating various peripheral circuits such as a ROM, a RAM, an A / D converter, an input / output port, and a recording medium for storing various data.

The input / output circuit 24 is connected to each other via a system device 25.

図３は、室外機制御装置２(ａ，ｂ，ｃ)における処理手順を示すフローチャートである。   FIG. 3 is a flowchart showing a processing procedure in the outdoor unit control device 2 (a, b, c).

室外機制御装置２(ａ，ｂ，ｃ)は、通信線６xを介して、他の空気調和機の通信データを傍受する。   The outdoor unit control device 2 (a, b, c) intercepts communication data of other air conditioners via the communication line 6x.

室外機制御装置２(ａ，ｂ，ｃ)は、傍受したデータから制御に必要となるエネルギー使用量，連続運転時間，連続停止時間，運転温度条件を取得する。   The outdoor unit control device 2 (a, b, c) acquires energy usage, continuous operation time, continuous stop time, and operation temperature conditions necessary for control from the intercepted data.

室外機制御装置２(ａ，ｂ，ｃ)は、データ取得後、主電源スイッチ１１から電源供給されるすべての空気調和機のエネルギー使用量を加算し、加算したエネルギー使用量を主電源スイッチ１１以下の契約電力である上限エネルギー使用量と比較する。   After the data acquisition, the outdoor unit control device 2 (a, b, c) adds the energy usage amounts of all the air conditioners that are supplied with power from the main power switch 11, and uses the added energy usage amounts for the main power switch 11. Compared with the maximum energy consumption, which is the contract power below.

室外機制御装置２(ａ，ｂ，ｃ)は、エネルギー使用量が上限エネルギー使用量以上となったら、自身の空気調和機の連続運転時間と他の空気調和機の連続運転時間とを比較し、自身の連続運転時間が一番長ければ、強制停止するとともに、再運転を所定時間防止するためにタイマカウントを開始する。   The outdoor unit control device 2 (a, b, c) compares the continuous operation time of its own air conditioner with the continuous operation time of other air conditioners when the energy use amount exceeds the upper limit energy use amount. If the continuous operation time is the longest, it is forcibly stopped and timer count is started in order to prevent re-operation for a predetermined time.
