Description

【0001】
【発明の属する技術分野】
本発明は、空調機器制御装置に関する。
【0002】
【従来の技術】
室内機および室外機を備えた空調機を起動する場合、一時的に過電流が流れるため、空調機を複数台有する空調システムにおいては、すべての空調機を同時に起動するのではなく、各室外機の起動時期をずらすようにしている(特開昭62−147253号公報)。
【0003】
【発明が解決しようとする課題】
ところが、各空調機のコンプレッサーを駆動する駆動源がガスエンジンの場合、定常運転に至るまでの時間が長くなるので、最初の空調機の起動開始と最後の空調機の起動開始との間の間隔が余りに長くなりすぎ、実用上、採用できないという不具合があった。
【0004】
それ故に、本発明は、かような不具合を除去した空調機器制御装置を提供することを、その技術的課題とするものである。
【0005】
【課題を解決するための手段】
上記技術的課題を解決するために、本発明の請求項1において講じた技術的手段は、複数の室内機、前記室内機に対応し、ガスエンジンで駆動されるコンプレッサーを内蔵する複数の室外機と、前記室外機および前記室内機を制御するとともに同時起動可能な室外機の最大数を設定する監視装置を備え、前記最大数の範囲内において、前記室外機が同時起動するようにしてなる、空調機器制御装置を構成したことである。
また、請求項2において講じた技術的手段は、請求項1記載の空調機器制御装置において、前記室外機の同時起動可能最大数は、前記ガスエンジン水温及び外気温度の相関により決定される環境条件に応じて設定される、構成としたことである。
【0006】
【作用および効果】
上記技術的手段による作用・効果は、以下の通りである。即ち、室外機は制限された数(最大数)だけ同時起動するので、室外機を順次間隔をおいて起動させる場合に比べて、全ての室外機を起動させる時間は、大幅に短縮される。
また、同時起動できる室外機の最大数は固定ではなく、ガスエンジン水温及び外気温度の相関により決定される環境条件に基づき設定されるので、きめ細かな制御ができて実用的である。
【0007】
【実施の態様】
以下、本発明の実施の態様を添付図面に基づいて説明する。
【0008】
図1において、空調システムは、48台のGHPエアコン(ガスヒートポンプエアコン)室外機1〜48およびこの室外機1〜48に対応する48台の室内機101〜148を備える。室外機1〜48および室内機101〜148は、共通の通信線201を介して集中監視装置202に接続されている。
【0009】
通信線201を流れる信号には、室内機・室外機間通信信号、集中監視装置・室内機/室外機間通信信号、特定の室外機から他の室外機および集中監視装置202への「起動中」信号がある。
【0010】
室外機1〜48の各々は制御装置(図示略)を備える。図2に示すフローチャートから明らかなように、例えば室外機は、他の室外機2〜48から発せられている「起動中」信号の個数が同時起動最大数未満である旨を確認した後、「起動中」信号ないし起動信号を送信し、起動を開始する。そして、起動後、つまりコンプレッサー(図示略)の駆動源たるガスエンジンが定常運転に達した後、起動解除信号を送信して、「起動中」信号ないし起動信号の送信を停止する。
【0011】
しかして、同時起動最大数は、ガスエンジン水温と外気温との相関をもとにマップ形式で事前に設定されており、これにより、同時起動時の起動電流制限するようになっている。また、かような環境条件により設定される同時起動最大数は、固定値ではなく、変動するものである。したがって、例えば、一時停止した後、再度、全ての空調機を稼働させる場合、同時起動最大数は、最初のそれよりも、大きくなる。
【0012】
図3に示すフローチャートから明らかなように、集中監視装置202は、室外機1〜48からから発せられている「起動中」信号の個数が同時起動最大数未満である限り、新たな室外機の起動を順次許可するようになっている。そして、図4に示すフローチャートから明らかなように、室外機の起動が失敗した場合、当該室外機からの「起動中」信号ないし起動信号の送信が停止され、他の室外機の起動が開始されることになる。これにより、他の室外機の起動が遅延するようなことはない。なお、起動が失敗した室外機の再起動は、所定の時間(待ち時間)経過後になされるようになっている。
【0013】
以上述べたように、室外機は制限された数(最大数)だけ同時起動するので、室外機を順次間隔をおいて起動させる場合に比べて、全ての室外機を起動させる時間は、大幅に短縮される。このメリットは、特に、各空調機のコンプレッサーを駆動する駆動源が、定常運転に至るまでの時間が長いガスエンジンの場合に顕著に現れる。
【0014】
また、同時起動できる室外機の最大数は固定ではなく、環境条件により可変ならしめたので、実用上、多大な効果を奏する。

BACKGROUND OF THE INVENTION
The present invention relates to an air conditioner control device.
[0002]
[Prior art]
When starting an air conditioner equipped with an indoor unit and an outdoor unit, an overcurrent temporarily flows. Therefore, in an air conditioning system having a plurality of air conditioners, not all the air conditioners are started simultaneously. The start-up time is shifted (Japanese Patent Laid-Open No. 62-147253).
[0003]
[Problems to be solved by the invention]
However, if the drive source that drives the compressor of each air conditioner is a gas engine, the time until steady operation becomes longer, so the interval between the start of starting the first air conditioner and the start of starting the last air conditioner However, there was a problem that it was too long to be used practically.
[0004]
Therefore, this invention makes it the technical subject to provide the air-conditioning equipment control apparatus which removed such a malfunction.
[0005]
[Means for Solving the Problems]
In order to solve the above technical problem, the technical means taken in claim 1 of the present invention includes a plurality of indoor units and a plurality of outdoor units corresponding to the indoor units and incorporating a compressor driven by a gas engine. comprising a machine and a monitoring device for setting the maximum number of concurrent bootable outdoor unit controls the front outdoor unit and the indoor unit, within the scope of the maximum number, the outdoor unit so as to simultaneously start That is, the air conditioner control device is configured.
The technical means taken in claim 2 is the air conditioner control apparatus according to claim 1, wherein the maximum number of the outdoor units that can be activated simultaneously is an environmental condition determined by the correlation between the gas engine water temperature and the outside air temperature. It is set as the structure set according to.
[0006]
[Action and effect]
The operations and effects of the above technical means are as follows. In other words, since a limited number (maximum number) of outdoor units are simultaneously activated, the time for starting all the outdoor units is greatly reduced as compared with the case where the outdoor units are activated sequentially at intervals.
In addition, the maximum number of outdoor units that can be started simultaneously is not fixed, but is set based on environmental conditions determined by the correlation between the gas engine water temperature and the outside air temperature, so that fine control is possible and practical.
[0007]
Embodiment
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
[0008]
In FIG. 1, the air conditioning system includes 48 GHP air conditioner (gas heat pump air conditioner) outdoor units 1 to 48 and 48 indoor units 101 to 148 corresponding to the outdoor units 1 to 48. The outdoor units 1 to 48 and the indoor units 101 to 148 are connected to the centralized monitoring device 202 via a common communication line 201.
[0009]
The signal flowing through the communication line 201 includes an indoor unit / outdoor unit communication signal, a centralized monitoring device / indoor unit / outdoor unit communication signal, a “starting” signal from a specific outdoor unit to another outdoor unit and the centralized monitoring unit 202. There is a signal.
[0010]
Each of the outdoor units 1 to 48 includes a control device (not shown). As apparent from the flowchart shown in FIG. 2, for example, the outdoor unit 1 confirms that the number of “active” signals emitted from the other outdoor units 2 to 48 is less than the maximum number of simultaneous activations. The “starting” signal or start signal is transmitted to start the start. Then, after the start-up, that is, after the gas engine that is the drive source of the compressor (not shown) reaches a steady operation, the start-release signal is transmitted to stop the transmission of the “starting” signal or the start-up signal.
[0011]
Thus, simultaneous starting maximum number, the correlation between the gas engine water temperature and outside air temperature are set in advance in a map format to the original, thereby, adapted to limit the starting current during simultaneous startup. Further, the maximum number of simultaneous activations set according to such environmental conditions is not a fixed value but varies. Therefore, for example, when all the air conditioners are operated again after being temporarily stopped, the maximum number of simultaneous activations becomes larger than the initial number.
[0012]
As is clear from the flowchart shown in FIG. 3, the centralized monitoring device 202 is configured so that the number of “starting” signals emitted from the outdoor units 1 to 48 is less than the maximum number of simultaneous activations. Starting is allowed sequentially. As is apparent from the flowchart shown in FIG. 4, when the outdoor unit fails to start, transmission of the “starting” signal or start signal from the outdoor unit is stopped, and the start of other outdoor units is started. Will be. As a result, the activation of other outdoor units is not delayed. The outdoor unit that has failed to start is restarted after a predetermined time (waiting time) has elapsed.
[0013]
As described above, since a limited number (maximum number) of outdoor units are activated at the same time, the time required to activate all the outdoor units is significantly longer than when the outdoor units are activated at sequential intervals. Shortened. This merit is particularly noticeable when the drive source that drives the compressor of each air conditioner is a gas engine that takes a long time to reach steady operation.
[0014]
In addition, the maximum number of outdoor units that can be activated simultaneously is not fixed, but is variable according to environmental conditions, so that there is a great practical effect.
