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、インバータ駆動手段の温度による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。   SUMMARY OF THE INVENTION 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 depending on the temperature of an inverter driving means.

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インバータ駆動手段温度検出手段で検出したインバータ駆動手段の温度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 adjusts the advance angle based on the temperature of the inverter drive means detected by the inverter drive means temperature detection means and the rotation speed detected by the compressor rotation speed detection means. To decide.

これによって、圧縮機の負荷条件が変動したときに前記インバータ駆動手段温度検出手段で検出したインバータ駆動手段の温度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。   Thereby, when the load condition of the compressor fluctuates, the advance angle is determined based on the temperature of the inverter drive means detected by the inverter drive means temperature detection means and the rotation speed detected by the compressor rotation speed detection means, The compressor can be controlled with an optimum advance angle under the load condition of the compressor.

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インバータ駆動手段温度検出手段で検出したインバータ駆動手段の温度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 of the present invention proceeds based on the temperature of the inverter driving means detected by the inverter driving means temperature detecting means when the load on the compressor fluctuates and the rotational speed detected by the compressor rotational speed detecting means. Since the angle can be determined and the compressor can be controlled with the optimum advance angle, the compressor can be controlled with high efficiency without stepping out even if the load fluctuates.

It can be, for each rotational speed of the compressor, it is possible to control the compressor optimally with high efficiency more load conditions.

第２の発明は、前記圧縮機の所定の回転数毎に上限進角、及び下限進角を前記圧縮機進角決定手段に記憶させたことを特徴とした請求項１記載の圧縮機制御装置とすることで、進角の決定範囲を限定することができ、より細かな進角の設定が可能となる。   2.

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. Note that the present invention is not limited to the embodiments.

（実施の形態１）
図１は、本発明の実施の形態１における圧縮機制御装置を示す図である。圧縮機１を駆動するインバータ駆動手段２と、前記インバータ駆動手段２の温度を検出するインバータ駆動手段温度検出手段３と、電源電圧８を整流して前記インバータ駆動手段２に供給される電圧を供給するダイオードブリッジ４と、前記圧縮機１の回転数を検出する圧縮機回転数検出手段５と、前記圧縮機１の進角を決定する圧縮機進角決定手段６と、前記圧縮機進角決定手段６で決定した進角で前記圧縮機１を制御する圧縮機制御手段７を備える。 (Embodiment 1)
FIG. 1 is a diagram showing a compressor control apparatus according to Embodiment 1 of the present invention. Inverter driving means 2 for driving the compressor 1, inverter driving means temperature detecting means 3 for detecting the temperature of the inverter driving means 2, and a voltage supplied to the inverter driving means 2 by rectifying the power supply voltage 8 A diode bridge 4 that performs this operation, a compressor rotation speed detection means 5 that detects the rotation speed of the compressor 1, a compressor advance angle determination means 6 that determines an advance angle of the compressor 1, and the compressor advance angle determination. Compressor control means 7 for controlling the compressor 1 with the advance angle determined by the means 6 is provided.

このように構成された圧縮機制御装置について、以下その動作、作用を、図２を用いて説明する。   The operation and action of the compressor control apparatus configured as described above will be described below with reference to FIG.

前記インバータ駆動手段温度検出手段３でインバータ駆動手段２の温度を検出し、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。前記インバータ駆動手段温度検出手段３で検出したインバータ駆動手段２の温度が所定の温度より低いときには圧縮機の負荷条件が軽いため、進角を小さく設定して高効率に圧縮機１を制御できる。前記インバータ駆動手段温度検出手段３で検出したインバータ駆動手段２の温度が所定の温度より高いときには負荷条件が重いため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。   The inverter drive means temperature detection means 3 detects the temperature of the inverter drive means 2, and the advance angle is determined based on the rotation speed detected by the compressor rotation speed detection means 5. Since the load condition of the compressor is light when the temperature of the inverter driving means 2 detected by the inverter driving means temperature detecting means 3 is lower than a predetermined temperature, the advance angle is set small and the compressor 1 can be controlled with high efficiency. When the temperature of the inverter drive means 2 detected by the inverter drive means temperature detection means 3 is higher than a predetermined temperature, the load condition is heavy, so that the advance angle can be set large to increase the step-out tolerance of the compressor 1.

これによって、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とすることができる。   As a result, the compressor can be controlled with an optimum advance angle under the load condition of the compressor.

（実施の形態２）
本実施の形態では、前記圧縮機１の所定の回転数毎に上限進角、及び下限進角を前記圧縮機進角決定手段６に記憶させたことを特徴とした圧縮機制御装置である。 (Embodiment 2)
In the present embodiment, the compressor control apparatus is characterized in that an upper limit advance angle and a lower limit advance angle are stored in the compressor advance angle determining means 6 for each predetermined number of revolutions of the compressor 1.

これによって、進角の決定範囲を限定することで、同一回転数内で負荷により上下限内で進角調整ができるので、より細かな進角の設定が可能となる。   Thus, by limiting the advance angle determination range, the advance angle can be adjusted within the upper and lower limits by the load within the same number of revolutions, so that a more advanced advance angle can be set.

以上のように、本発明にかかる制御装置は、負荷条件が変動したときでも最適な進角で圧縮機を制御することが可能となるので、より負荷条件に適した高効率な圧縮機駆動制御をする制御装置に適用できる。   As described above, the control device according to the present invention can control the compressor with the optimum advance angle even when the load condition fluctuates. Therefore, highly efficient compressor drive control more suitable for the load condition. It can be applied to a control device that
