AN APPLICATION OF MICROPROCESSOR TECHNOLOGY TO SUPERMARKET REFRIGERATION.

Author(s) : MCGUIRE R. G., RADFORD P. E.

Type of article: Periodical article

Summary

THE PAPER LISTS THE NORMAL ELECTRO-MECHANICAL CONTROLS USED FOR A SPECIFIC SUPERMARKET REFRIGERATION SYSTEM WITH MULTIPLE LOADS AND A CENTRAL COMPRESSOR AND CONDENSER SYSTEM. THE CHANGE IS DESCRIBED TO AN ELECTRONIC SYSTEM USING MICROPROCESSORS BASED ON SIMPLE ALGORITHMS FOR THE VARIOUS CONTROL REQUIREMENTS. THE ONLY ALTERATIONS TO THE REFRIGERATION PLANT ARE THE REPLACEMENT OF EXPANSION VALVES AND BACK-PRESSURE VALVES BY ELECTRICALLY DRIVEN DEVICES. THE ADVANTAGES OF THE NEW TECHNOLOGY ARE IN ITS ABILITY TO MEASURE AND ACT UPON MORE VARIABLES INDICATING EXACT COOLING REQUIREMENTS, ETC. ALSO COMPRESSOR RUNNING CAN BE OPTIMISED BY MODIFYING THE ORDER OF OPERATION ON MEASUREMENT OF RUNNING TIME AND AVAILABILITY. IN GENERAL A MORE EXACT AND ENERGY EFFICIENT SYSTEM CAN BE PRODUCED WITH BETTER POTENTIAL FOR ACCURATE FAULT ANALYSIS. D.W.H.
