Abstract

Um einen Schraubenverdichter umfassend zwei in einem Verdichtergehäuse in Schraubenläuferbohrungen angeordnete Schraubenläufer, welche ein an einem Kältemitteleinlaß eintretendes Kältemittel verdichten und an einem Kältemittelauslaß austreten lassen, und einen in dem Verdichtergehäuse vorgesehenen Einlaß für aus einem Unterkühlungskreislauf kommendes, in einem Leitungssystem zum Einlaß geführtes Kältemittel, wobei der Einlaß derart angeordnet ist, daß er in von den Schraubenläufern und den Schraubenläuferbohrungen umschlossene Verdichtungsräume mündet, zu schaffen, bei welchem die am Einlaß auftretende Druckschwingungen oder Pulsationen sich in möglichst geringem Maße auf das Rohrleitungssystem des Unterkühlungskreislaufs außerhalb des Verdichtergehäuses fortpflanzen, wird vorgeschlagen, daß dem Einlaß ein dem Leitungssystem zugeordneter Dämpferkanal vorgeschaltet ist, in welchem Kältemittel aus dem Unterkühlungskreislauf vorliegt.

Figure 00000001
To a screw compressor comprising two in a compressor housing in Schraubenläuferbohrungen arranged screw rotors which compress a refrigerant inlet at a refrigerant inlet and leak at a refrigerant outlet, and provided in the compressor housing inlet for coming from a subcooling circuit, fed in a conduit system to the inlet refrigerant the inlet is arranged to open into compression spaces enclosed by the screw and screw rotor bores, in which the pressure oscillations or pulsations occurring at the inlet propagate as little as possible to the piping system of the subcooling circuit outside the compressor housing, it is proposed that the intake is preceded by a damper channel assigned to the line system, in which refrigerant is present from the subcooling circuit.
