    摘要: A method and apparatus for refrigeration system control are provided. The refrigeration system includes a plurality of circuits (26) with each circuit having at least one refrigeration case (22). An electronic evaporator pressure regulator (28) 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 (18). A pressure sensor (36) 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 (30) controls each electronic evaporator pressure regulator and the suction pressure based upon the measured parameters from each circuit.

    摘要: A system and method for controlling refrigeration including a temperature sensor (50) operable to measure a temperature from a refrigeration case (22) and a transceiver (82) in communication with the temperature sensor and operable to wirelessly transmit data. A repeater receives the wirelessly transmitted data and further wirelessly transmits the data to a receiver (94). A controller (30) in communication with the receiver controls the refrigeration system based upon the wirelessly transmitted data from the refrigeration case. The refrigeration case also includes a mode switch for suspending temperature reading and control for a period of time. For example, the mode switch can be used by an operator during cleaning or maintenance of the refrigerator case.; Temperature control algorithms are used by the controller, and include: dead-band range (DB), proportional/integral (PI), proportional/integral/differentiation (PID) and fuzzy-logic (FL).
