EJECTOR REFRIGERATION CIRCUIT Russian patent published in 2019 - IPC F25B1/10 

FIELD: refrigerating equipment.

SUBSTANCE: invention relates to a method for controlling ejector refrigeration circuit (1) with at least two controlled ejectors (6, 7) connected in parallel and containing, respectively, controllable working nozzle (100), primary inlet port (6a, 7a) of high pressure, which forms the inlet of working nozzle (100), secondary inlet port (6b, 7b) of low pressure and outlet port (6c, 7c). Method includes the operation of first ejector (6) by controlling the degree of opening of its primary inlet port (6a) of high pressure to achieve maximum efficiency of specified first ejector (6) or meeting the actual cooling demand and the operation of at least one additional ejector (7) by gradually opening its primary inlet port (6a, 7a) of high pressure to increase the cooling capacity of ejector refrigeration circuit (1) in case the real need for cooling is not satisfied when only first ejector (6) is operating.

EFFECT: technical result is to increase the reliability and optimize the efficiency of the refrigerant circuit in a wide range of operating conditions.
