Abstract: The method involves measuring two parameters from two circuits, where the circuits include two refrigeration cases (22). Two valve positions are determined for two electronic evaporator pressure regulators associated with the circuits based upon the parameters. The regulators are electronically controlled to control temperature in the circuits. A high pressure liquid refrigerant is delivered to the cases by way of piping. An independent claim is also included for an apparatus of controlling a refrigeration system.

Abstract: 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).
