Method and apparatus for refrigeration system control having electronic evaporator pressure regulators

摘要

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.
