<p>A system (170) has a compressor (22). A heat rejection heat exchanger (30) is coupled to the compressor to receive refrigerant compressed by the compressor. A non - controlled ejector (38) has a primary inlet coupled to the heat rejection exchanger to receive refrigerant, a secondary inlet, and an outlet. The system includes means (172, e.g., a nozzle) for causing a supercritical-to-subcritical transition upstream of the ejector.</p> |
