Description
Die Erfindung betrifft eine Kälteerzeugungsmaschine, bei welcher das Kältemittel mittels eines Kreiselverdichters verdichtet wird.The invention relates to a refrigeration machine in which the refrigerant means a centrifugal compressor is compressed.
Bei den bekannten Kreiselverdichtern, die zur Verdichtung von Luft dienen, wird Wasser als Kühlmittel in die zu verdichtende Luft eingespritzt. Diese Art der Kühlung mit Wasser ist aber bei Kälteerzeugungsmaschinen nicht anwendbar, weil die nachträgliche Trennung ίο des Wassers von dem Kältemittel schwierig ist und die erforderliche tiefe Temperatur wegen der Eisbildung noch besondere Gefahren mit sich bringt.In the known centrifugal compressors, which are used to compress air, water injected as a coolant into the air to be compressed. This type of cooling with water but cannot be used for refrigeration machines because of the subsequent separation ίο the water from the refrigerant is difficult and the required low temperature because of the ice formation still brings with it special dangers.
Gemäß der Erfindung wird zur Kühlung des Verdichters ein Teil des verflüssigten Kältemittels durch Einspritzen in den Verdichter dem zu verdichtenden Kältemittel beigemengt.According to the invention, part of the liquefied refrigerant is used to cool the compressor added to the refrigerant to be compressed by injection into the compressor.
Es ist zwar schon bekannt, das Kältemittel im flüssigen Zustande bei Kolbenkompressoren in das dampfförmige zu verdichtende Kältemittel behufs Kühlung einzuführen. Jedoch ist bei Kolbenkompressoren eine gleichmäßige Kühlung deshalb nicht möglich, weil sich die Flüssigkeit im Zylinder an der tiefsten Stelle ansammelt und die übrigen Stellen der Zylinderoberfläche unbenetzt läßt. Beim Kreiselverdichter wird hingegen das flüssige Kältemittel gemäß der Erfindung durch die Zentrifugalkraft auf den Kreiselflächen ausgebreitet und das Kühlmittel vermöge der Zentrifugalkraft gezwungen, sich in allen Schaufelräumen, die im Gegensatz zum Kolbenkompressor verhältnismäßig enge Kanäle bilden, mit dem zu verdichtenden Gas innig zu mischen, wodurch eine weitere Erhöhung der Kühlwirkung erreicht wird.It is already known that the refrigerant is in the liquid state in reciprocating compressors to be introduced into the vaporous refrigerant to be compressed for cooling. However Even cooling is not possible with reciprocating compressors because the Liquid accumulates in the cylinder at the deepest point and the remaining points on the cylinder surface leaves unwetted. In the case of the centrifugal compressor, however, the liquid refrigerant according to the invention is released by centrifugal force Spread out on the surfaces of the gyroscope and the coolant by means of centrifugal force forced to form in all vane spaces, which in contrast to the piston compressor, form relatively narrow channels, to mix intimately with the gas to be compressed, thereby further increasing the cooling effect is achieved.
