*c-Ejector

*c-Ejector is used for efficiency increase in CO₂ booster systems. In connection with a high pressure valve, three different types of gas ejectors and two types of liquid ejectors may be combined as required.

Efficiency increases of 15 – 30% are possible (compared to a booster system with flash gas bypass)

Lower compressor capacity required (smaller/fewer compressors)

Individually adaptable to every applica¬tion and every performance parameter

Air conditioning and/or heat pump evaporator may be integrated

Extended lifetime of the parallel compressor, even at low outside temperatures

High reliability (no moving or rotating parts)

Short payback time (depending on the size of the plant)

Refrigerant: R744

Max. operating pressure: 120 bar

Tested according to AD 2000: 1.1 x 120 bar

Temperature of medium: – 50 °C … + 150 °C

Ambient temperature: – 10 °C … + 50 °C

Material: stainless steel 1.4301

Weight: 1,3 kg

*c-Ejector utilises the expansion work present in the refrigerant to draw in another partial flow and convey it to a higher pressure level.

The CO₂ leaving the gas cooler at high pressure is accelerated in the motive nozzle. As a result, the static pressure drops. The flow exiting the motive nozzle has a lower pressure than the suction pressure of the MT- stage.

Either gas or liquid can be extracted from the suction side of the MT-compressor.

Both partial flows mix in the mixing chamber.

The flow is decelerated again in the diffuser, which raises the pressure to medium pressure level. After this stage, the mixture is fed into the medium-pressure separator.
