<p>ENERGY MANAGEMENT SYSTEM FOR REFRIGERATION SYSTEMS A system and method for managing energy in large refrigeration systems and the like by continuously monitoring operating parameters and controlling to optimize the refrigeration system elements. A multiplicity of remote sensors is disposed at the appropriate points in the refrigeration system to produce electrical signals representative of various temperatures and various pressures in the system. A signal processor is provided to receive signals from the sensors and to calculate the instantaneous system operating parameters from the signals, to compare these parameters to the design parameters, to operate controls to maintain optimum system pressures, to energize and deenergize fans and pumps in accordance with the system requirements, and to produce alarms when problems are indicated in the refrigeration system.</p> |
