Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem that a compressor cannot be controlled by a more optimum lead angle under a load condition of the compressor since the lead angle is decided irrespective of load fluctuation of the compressor as the lead angle decided at every revolution of the compressor is stored in a compressor lead angle deciding means and the compressor is controlled in a compressor controller. <P>SOLUTION: The lead angle is decided based on a compressor current detected by a compressor current detecting means 3 and a revolution detected by a compressor revolution detecting means 5. Thus, the compressor can be controlled with the optimum lead angle. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

本発明は圧縮機制御装置に関するものである。   The present invention relates to a compressor control device.

従来は図３に示すように、圧縮機の回転数毎に定められた進角だけを前記圧縮機進角決定手段に記憶させて圧縮機を制御している（例えば、特許文献１参照）。
特開２００６−２０４０５０号公報 Conventionally, as shown in FIG. 3, only the advance angle determined for each rotation speed of the compressor is stored in the compressor advance angle determining means to control the compressor (see, for example, Patent Document 1).
JP 2006-204050 A

しかしながら、前記従来の圧縮機制御装置では、圧縮機の回転数毎に定められた進角を前記圧縮機進角決定手段に記憶させて圧縮機を制御しているため、圧縮機の負荷変動に関係なく進角が決定されるので、高効率に圧縮機を制御するために進角を小さく設定すると負荷が大きいとき圧縮機の脱調耐量が下がるという課題を有していた。   However, in the conventional compressor control apparatus, since the advance angle determined for each rotation speed of the compressor is stored in the compressor advance angle determining means and the compressor is controlled, the load fluctuation of the compressor is caused. Since the advance angle is determined irrespectively, there has been a problem that if the advance angle is set small in order to control the compressor with high efficiency, the step-out tolerance of the compressor decreases when the load is large.

また、脱調耐量を上げるために進角を大きく設定すると負荷が小さいとき圧縮機の効率が悪くなるという課題を有していた。   In addition, if the advance angle is set large in order to increase the step-out tolerance, the efficiency of the compressor deteriorates when the load is small.

本発明は、前記従来の課題を解決するもので、圧縮機の負荷条件において最適な進角で圧縮機制御を可能にすることを目的とする。   The present invention solves the above-described conventional problems, and an object thereof is to enable compressor control at an optimum advance angle under a load condition of the compressor.

前記従来の課題を解決するために、本発明の圧縮機制御装置は圧縮機に供給される電流を検出する圧縮機電流検出手段で検出した圧縮機電流と圧縮機回転数検出手段で検出した回転数に基づいて進角を決定するものである。   In order to solve the above-mentioned conventional problems, the compressor control device of the present invention is a compressor current detected by a compressor current detecting means for detecting a current supplied to the compressor and a rotation detected by the compressor rotational speed detecting means. The advance angle is determined based on the number.

これによって、圧縮機の負荷条件が変動したときに前記圧縮機電流検出手段で検出した圧縮機電流と前記圧縮機回転数検出手段で検出した回転数に基づいて進角を決定し、圧縮機の負荷条件において最適な進角で圧縮機制御を可能にすることができる。   Thus, the advance angle is determined based on the compressor current detected by the compressor current detection means and the rotation speed detected by the compressor rotation speed detection means when the load condition of the compressor fluctuates. The compressor can be controlled with an optimum advance angle under load conditions.

本発明の圧縮機制御装置は、圧縮機の負荷が変動したときに前記圧縮機電流検出手段で検出した圧縮機電流と前記圧縮機回転数検出手段で検出した回転数に基づいて進角を決定し、最適な進角で圧縮機制御を可能にすることができるため、負荷変動しても圧縮機が脱調することなく高効率で制御できる。   The compressor control device according to the present invention determines an advance angle based on the compressor current detected by the compressor current detection means and the rotation speed detected by the compressor rotation speed detection means when the load of the compressor fluctuates. In addition, since the compressor can be controlled with an optimum advance angle, the compressor can be controlled with high efficiency without stepping out even if the load fluctuates.

Each time, more load conditions It is possible to control the compressor optimally at high efficiency.

The compressor control device according to claim 1, wherein an upper limit advance angle and a lower limit advance angle are stored in the compressor advance angle determination means for each predetermined rotation speed of the compressor. By doing so, the advance angle determination range can be limited, and a finer advance angle can be set.

以下、本発明の実施の形態について、図面を参照しながら説明する。なお、この実施の形態によって本発明が限定されるものではない。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, this invention is not limited by this embodiment.

本発明は、図２に示すように、前記圧縮機電流検出手段３で圧縮機電流を検出し、前記圧縮機回転数検出手段５で検出した回転数に基づいて進角を決定することができる。前記圧縮機電流検出手段３で検出した圧縮機電流が小さいときには進角を小さく設定して高効率に圧縮機１を制御できる。前記圧縮機電流検出手段３で検出した圧縮機電流が大きいときには進角を大きく設定して圧縮機１の脱調耐量を上げることができる。   In the present invention, as shown in FIG. 2, the compressor current detection means 3 detects the compressor current, and the advance angle can be determined based on the rotation speed detected by the compressor rotation speed detection means 5. . When the compressor current detected by the compressor current detecting means 3 is small, the advance angle is set small and the compressor 1 can be controlled with high efficiency.

In the present embodiment, the compressor control device is characterized in that an upper limit advance angle and a lower limit advance angle are stored in the compressor advance angle determination means 6 for each predetermined rotation speed of the compressor 1.

Therefore, highly efficient compressor drive control more suitable for the load condition. It is applicable to a control device that performs
