Abstract
A method for evacuating a process space by initially evacuating the process space to a pressure limit value using two compressors operated in parallel, and on reaching or undershooting the pressure limit value, the process space is subsequently evacuated using the two compressors operated in series.
Claims10
A system configured to evacuate a fully enclosed and sealed process space having a fixed volume, comprising:
- a first inflow line;
- a first compressor configured to be coupled to the sealed process space via the first inflow line;
- a first outflow line configured to discharge medium extracted from the enclosed and sealed process space by the first compressor into a surroundings;
- a second inflow line;
- a second compressor configured to be coupled to the enclosed and sealed process space via the second inflow line;
- a second outflow line configured to discharge the medium extracted from the enclosed and sealed process space by the second compressor into the surroundings;
- a connecting line connected between the first outflow line and the second inflow line;
- a first inflow line valve integrated in the first inflow line;
- a second inflow line valve integrated in the second inflow line;
- a first outflow line valve integrated in the first outflow line;
- and
- a connecting line valve integrated in the connecting line,
- wherein when the first inflow line valve, the second inflow line valve, and the first outflow line valve are all opened and the connecting line valve is closed, the first compressor and the second compressor are operable in parallel, and
- wherein when the first inflow line valve and the connecting line valve are both opened and the second inflow line valve and the first outflow line valve are both closed, the first compressor and the second compressor are operable in series,
- wherein the first compressor and the second compressor evacuate the medium from the fully enclosed and sealed process space to create a vacuum in the fixed volume of the fully enclosed and sealed process space.
