System and method for controlling a plurality of ejectors in an ejector refrigeration circuit

Abstract

A system for controlling a plurality of ejectors in an ejector refrigeration circuit includes the plurality of ejectors and a controller. Each of the plurality of ejectors include a primary high pressure input port, a secondary low pressure input port, and an output port. The controller is coupled to each of the plurality of ejectors and adapted to generate a plurality of maps based on a set of predefined conditions. Each of the plurality of maps is associated with a corresponding temperature of a heat rejecting heat exchanger. The controller identifies a first map from the plurality of maps associated with a first temperature of the heat rejecting heat exchanger and an input signal from a first ejector indicative of a flow rate of a refrigerant fluid through the first ejector. Finally, the controller adjusts opening percentages of the plurality of ejectors based on the identified first map.
