11.4 SPECIFIC FUNCTIONS COMPARED WITH A TRADITIONAL TRANSCRITICAL SYSTEM:
11.4.1 Ejector :
The ejector as a component works using a high pressure and high density fluid (here downstream the gas cooler) as motive flow and sucks from a
secondary fluid (or the same one) from the suction port to compress the resulting mixture. This ejector has three parts. The first part, the motive
nozzle, converts the high inlet pressure into low pressure with high velocity. The motive flow then enters the second part of the ejector, the mixer
chamber, while the velocity is still high and the pressure is lower than suction pressure. Suction flow enters the mixer chamber and is accelerated
by the motive flow in the mixer section. These mixed streams enter the diffuser, the third part of the ejector, and convert their velocity back
into pressure, with the exit pressure being higher than the suction inlet. In essence, in the CO2OLtec EVO system, the ejector uses the high-
pressure energy to pre-compress the full suction mass flow from suction pressure to a higher pressure.
The ejector recovers the energy that is usually lost during the high pressure expansion process.
