Abstract (en)
Refrigeration system using CO<sub>2</sub> as the refrigerant is disclosed. The system (20) comprises a plurality of ejectors (2, 2', 2", 2‴) are arranged in parallel. Each of the ejectors (2, 2', 2", 2‴) comprises a motive port (8) and a suction port (20). Each of the ejectors (2, 2', 2", 2‴) has a fixed geometry. A first actuated ball valve (4, 4', 4", 4‴) is arranged in front of the motive port (8). A second actuated ball valve (6, 6', 6", 6‴) is arranged in front of the suction port (10). The system (20) comprises a control unit (12) arranged and configured to control the activity of the ball valves (4, 4', 4", 4‴, 6, 6', 6", 6‴) on the basis of one or more predefined criteria.
