*c-Ejector utilizes the expansion work present in the refrigerant to suck in a different partial flow and convey it to a higher pressure level.
The CO2 exiting the gas cooler at high pressure is accelerated in the jet nozzle. As a result, the static pressure decreases. The flow emerging from the nozzle has a lower pressure than the suction pressure of the NK stage.
Optionally, gas or liquid can be drawn off from the suction side of the NK compressors.
Both partial flows mix in the mixing chamber.
In the diffuser, the flow is decelerated again, which causes a pressure increase to medium pressure level. After the diffuser, the mixture is fed into the medium pressure separator.
