System and method for map-interpolation based control of ejectors in an ejector refrigeration circuit

A system for map-interpolation based control of a plurality of ejectors in an ejector refrigeration circuit, the system comprising:

• a plurality of ejectors, each of the plurality of ejectors having a primary high pressure input port, a secondary low pressure input port, and an output port;
• and
• a controller coupled to each of the plurality of ejectors, the controller adapted to:
• generate a plurality of maps based on a set of predefined conditions, each of the plurality of maps associated with a corresponding temperature of a heat rejecting heat exchanger;
• identify a first map from the plurality of maps associated with a first temperature of the heat rejecting heat exchanger and an input signal indicative of a flow rate of a refrigerant fluid through the first ejector;
• identify a second map from the plurality of maps associated with a second temperature of the heat rejecting heat exchanger;
• predict an opening percentage of the first ejector from at least one of a plurality of opening percentages indicated in the first map and a plurality of opening percentages indicated in the second map;
• and
• adjust the opening percentage of the first ejector based on the predicted opening percentage.
