企业简介
图01 — Compact Enjector
01 概览
In conjunction with a high-pressure valve, three different types of gas and two types of liquid ejectors can be combined as desired.
01
Features
- Efficiency increases of 15-30% possible (compare with a booster system with flash gas bypass)
- Lower compressor capacity required (smaller or fewer number of compressors)
- Can be individually tailored to each application and each performance level
- Air conditioning and/or heat pump evaporator can be integrated
- Extended running time of the parallel compressor even at lower outside temperatures
- High reliability (no moving or rotating components)
- Short payback period (depending on system size)
Function – Principle of operation
* c -Ejector uses the expansion work present in the refrigerant to suck in another partial flow and transport it to a higher pressure level.
The CO₂ emerging from the gas cooler at high pressure is accelerated in the motive nozzle. As a result, the static pressure drops. The flow emerging from the motive nozzle has a lower pressure than the suction pressure of the NK stage.
02
Either gas or liquid can be extracted from the suction side of the NK compressors.
Both partial streams mix in the mixing chamber.
03
In the diffuser, the flow is slowed down again, which causes a pressure increase to medium pressure level. After the diffuser, the mixture is fed into the medium pressure separator.
