Abstract
A system for detection and correction of reverse flow in an ejector refrigeration circuit, includes ejectors, first sensors for measuring an ejector suction superheat of a refrigerant at a secondary low pressure input port of each of the ejectors, and a second sensor for measuring a superheat of the refrigerant upstream relative to the secondary low pressure input port. A controller receives the ejector suction superheats and the refrigerant superheat and determines whether a superheat difference between each of the ejector suction superheats and the refrigerant superheat falls below a threshold superheat difference. The controller identifies a first ejector as a reverse flow affected ejector based on the determined superheat difference. The controller compares opening percentages of the ejectors to determine a second ejector having the largest opening percentage and controls the first ejector and the second ejector to increase a refrigerant flow rate of the first ejector.
