Abstract
A method and apparatus for refrigeration system control is provided. The refrigeration system includes a plurality of circuits with each circuit having at least one refrigeration case. An electronic evaporator pressure regulator is in communication with each circuit and is operable to control the temperature of the corresponding circuit. A plurality of compressors are also provided with each compressor forming a part of a compressor rack. A pressure sensor is used for measuring the suction pressure of the compressor rack. A sensor is in communication with each circuit and is operable to measure a parameter from each circuit. A controller controls each electronic evaporator pressure regulator and the suction pressure based upon the measured parameters from each circuit.
