How Multi ejectors work - working principle CO2 refrigeration

The video discusses the transition from traditional HFC refrigerants to CO2 (R744) due to environmental concerns. It explains the efficiency of CO2 in cooler climates and the challenges in warmer regions. The video details the evolution of CO2 refrigeration systems from first to third generation, highlighting the introduction of parallel compressors and the multi ejector. The multi ejector's operation is explained, showing how it improves system efficiency by mixing refrigerants at different pressures.
